July 20. 2020 Important update on superspreading events.

This article from the Washington Post provides a useful update about how superspreading events account for the vast majority of infection and are driving the pandemic. 3-5 minute read.

July 5, 2020 Hopeful news on speedy SARS-COV-2 testing!

The US federal government is doing a terrible job at tracking cases compared to many other countries. But if some of the fast, low cost technologies for individual testing mentioned in this NY Times Opinion piece actually work, it will make it a lot easier for individuals, schools, firms and motivated local governments to do so.

June 17, 2020 World War I and II comparisons

 Today’s Boston Globe features the news that COVID-19 deaths in the US  – currently 119,000  –  now exceed those in World War I. Of course the US population was much lower then. During World War II there were 407,316 service men who died (0.29 percent of the US population). Think of all those flags for WWII veterans you saw on Memorial Day recently.  It will take real determination and action to keep US deaths from COVID-19 – currently about 800 per day, or 24,000 per month – below the tragic WWII levels.

June 17, 2020 Be selfish and wear a mask!

Yesterday I ate dinner outside on the main thoroughfare (Moody Street) in Waltham which has been converted into a massive pedestrian way to allow people to eat outside while more than 3 meters apart. I was sad to see dozens of people on the streets not properly wearing masks. I thought of a good selfish reason why everyone should want to do so. Just as high altitude dwellers develop stronger and larger lungs in order to get enough oxygen, securely wearing a high quality mask that cuts off the air flow a bit and results in slightly less oxygen reaching your lungs enables low altitude people to develop stronger and larger lung capacity. The extra effort it takes to breath is no different from lifting more weights or running a bit faster, and builds up your lungs at a time when you may really need them to fend of COVID-19 respiratory failure. I don’t hear weightlifters or joggers complaining about their difficulties: they want the challenge. Wear a high quality mask for your own future health!

June 11, 2020 Words from Michael Osterholm, epidemiologist

I am sharing this informative interview with a very knowledgeable person, even though I disagree with his assessment on several important points.

I have added my comments at the bottom of this summary from the article, while striking out three statements asserted there.

COVID-19: Straight Answers from Top Epidemiologist Who Predicted the Pandemic

https://www.bluezones.com/2020/06/covid-19-straight-answers-from-top-epidemiologist-who-predicted-the-pandemic/

By Dan Buettner, Blue Zones Founder [Interview conducted on May 29, 2020. Published on June 6, 2020]

Below is the summary from within that article.

In short, Dr. Osterholm is arguably one of the most dependable, non-political sources for straight answers on what COVID-19 means to us and our world in the immediate future. In his 2017 book, Deadliest Enemy, he correctly foretells a global pandemic and offers the best strategy for fighting it now and avoiding it in the future.

Here are the highlights of our conversation. But if you really want to understand this disease, read the whole interview.  This disease may be the biggest event of our lifetimes.

  • 3 months ago, COVID-19 was not even in the top 75 causes of death in this country. Much of the last month, it was the #1 cause of death in this country. This is more remarkable than the 1918 Flu pandemic.
  • There is no scientific indication Covid-19 will disappear of its own accord.
  • If you’re under age 55, obesity is the #1 risk factor. So, eating the right diet, getting physical activity, and managing stress are some of the most important things you can do to protect yourself from the disease.
  • One of the best things we can do for our aging parents is to get them out into the fresh air, while maintaining physical (not social) distancing.
  • Wearing a cloth mask does not protect you much if you’re in close contact with someone who is COVID-19 contagious. It may give you 10 minutes, instead of five, to avoid contracting the disease.
  • We can expect COVID-19 to infect 60% – 70% of Americans. That’s around 200 million Americans.
  • We can expect between 800,000 and 1.6 million Americans to die in the next 18 months if we don’t have a successful vaccine.
  • There is no guarantee of an effective vaccination and even if we find one, it may only give short term protection.
  • Speeding a vaccination into production carries its own risks.
  • The darkest days are still ahead of us. We need moral leadership, the command leadership that doesn’t minimize what’s before us but allows everyone to see that we’re going to get through it.

I strongly disagree with his statement that wearing a cloth mask does not protect you much. It is true that if I were tending a COVID-19 infected patient, it would be highly inadequate, because of the duration of the exposure. But for ordinary activities, even briefly near someone who is infected, then universal mask wearing by both the infected and the rest of the population can bring down the rate of new infections below 1.0, and largely eliminate or drastically slow down exposure in a population. This is why New Zealand has had zero deaths over an extended period, and why rates are also extremely low in Japan, Hong Kong, South Korea and certain other Asian countries. All of these countries have had nearly universal mask wearing, as well as excellent case identification and quarantining.

The research on masks shows that a simple, homemade cotton mask filters out about 70% effective at suppressing germ aerosols, particularly larger particles that can projectile the farthest from a sneeze, cough or singing. Masks also reduce touching your mouth, nose and eyes, even if they don’t eliminate any aerosol contamination. Better “surgical quality” masks can achieve over 95% protection with 99% claimed by N95 masks. (To some degree, the greater risk may be putting on and taking off high quality masks frequently to maintain their effectiveness…) There is no reason we could not all be wearing surgical quality masks when shopping or around others. This would greatly slow down transmission.

If a random COVID-19 contagious person without any PPE protection infects 3 people,  then even a 70% effective mask reduces the average number of people infected to .3*3 = .9 newly infected for each person contagious. That is less than 1! So the disease would gradually die out. With a 90% effective PPE, new infection rate would be cut to less than a third, and infections would die out even faster.

PPE is why in Japan millions of people are now commuting daily by public transport on crowded subways and buses with minor numbers of new cases: masks do work. We could do that if we all wore masks, testing was widespread, and we were willing to track cases and enforce quarantines.

I also disagree with the papers blind prediction that COVID-19 will necessarily infect 60-70 percent of the worlds population. The same experience from other countries show that careful testing quarantining, and mask wearing could keep rates below 60% of the population, particularly the at-risk population, for over a year, when hopefully a vaccine will be available for at least high risk people. Recall that until a few years ago flu vaccines were reserved only for older and higher risk segments of the population. This is what will be needed this time as well, when a COVID-19 vaccine is created, since we cannot immediately create 8 billion vaccines for the whole world.

The article starts with a really crazy statement:

“One of the things we have to understand is that this virus is operating under the laws of physics, chemistry, and biology. It doesn’t in any way, shape, or form bend itself to public policy.”

If it were true that science drives everything and public policies do not matter, then why do we even need doctors and hospitals? Or why does physical distancing matter? Clearly public policy AND PRIVATE DECISIONS matter a lot, as the article goes on to highlight.

I agree that each country needs a leader like Franklin Delano Roosevelt who is unselfish and totally committed to leading the public sentiment in a positive direction. A few countries have been blessed with this, and we should be learning from their successes.

My own wish is that more attention would focus on the following facts.

  • The death rate is not some constant for each health care system, but rather it will go up if a health care system gets overcrowded and cannot keep up. It could be that with optimal treatment in a well-endowed health care system, the death rate is only 0.5% of those infected (across the whole population). But if there are not enough hospital beds, trained doctors, staff, ICUs and ventilators, then the death rate could be 5%. This is the great value of policies to slow down rates of infection.
  • A significant part of the burden of high rates of COVID-19 is the consequences of all the avoided preventive and curative treatment of OTHER diseases. Heart conditions, cancer, vaccine preventable infections.  This is another reason to want to keep the flow rate of new infections manageable.
  • While everyone is focusing on when there will be a vaccine, of greater likelihood is that we will develop treatment strategies that can further reduce mortality and serious illness. This is what is more likely in the near term.
  • I think it is too early  to tell whether death rates by the rest of the world are much better than in Sweden, which has encouraged private actions but not shut down and mandated self-quarantines. We have so far DELAYED infections and deaths meaningfully in the US and many other countries, but whether we have prevented them over say the next year will depend on what happens this fall and winter.
  • There is far too little effort and research discussing how to better target social distancing and public polices to people at greatest risk. Shutting down all businesses is a very blunt tool for doing this.
  • The findings that high altitudes have lower rates of infection is likely not the result of the virus not finding conditions less hospitable at low air density or humidity, but rather that at high altitude people develop larger lungs and stronger lung muscles that make them better able to fight off the virus. Working out hard can do much the same thing for many of us.
  • Obesity affects heart and circulatory diseases in part because the fat clogs up arteries and veins.  For COVID, a different mechanism may be that obesity increases the weight that the lung muscles have to raise and lower with each breath, which leads to faster respiratory failure and requires the really nasty ventilators that replace muscles and cause all kinds of problems of their own. We all know that repeatedly raising your arms while holding even a one pound weight soon wears your arms out. The same must be true for breathing with extra pounds of weight on your chest and stomach. The shrotness of breath symptom of COVID-19 can force you to breath hard for hours or days at a time.
  • There is evidence in JAMA just out from China that shoes spread around germs all over the floor when people walk in areas around infected people, even if those people are not showing any symptoms. Most of us don’t touch the floors much, but infants do. While symptoms are concentrated among the old populations, US studies show that infection rates are pretty uniform across all ages. Parents should not let very young children crawl on floors in public places.
  • Teens and college age students are especially prone to large gatherings  (sports, concerts, bars,…) in which people mingle with strangers, and many infected do not display symptoms. While serious cases are rare, they are also likely to be a very strong source of new infections.

June 8, 2020 More on Race and likely futures

Covidtracking.com is an new source of raw data on COVID-19 statistics for the US, and now includes a new tracking of cases and deaths by race.

This source is the new standard being quoted by the media, including by the White House and CDC. I have not compared it to the NY Times and WorldOMeters.com sources that I have previously linked.

I am not sure I agree with the consensus, but this survey out just today of epidemiologists by the NY Times gives a very sobering overview of when we might expect to return to a wide range of normal activities.

What’s the Risk of Catching Coronavirus From a Surface?

May 21, 2020 Steps hospitals use to minimize COVID-19 and more

Excellent article by Atul Gawande in the NYTimes magazine. Probably a 20 minute read.

Health-care workers have been on the job throughout the pandemic. What can they teach us about the safest way to lift a lockdown?

Key takeaways for me:

“Is there any place that has figured out a way to open and have employees work safely, with one another and with their customers?” Yes.  Mass General Brigham,  … seventy-five thousand employees—more people than in seventy-five per cent of U.S. counties. In April, two-thirds of us were working on site. Yet we’ve had few workplace transmissions. Not zero: we’ve been on a learning curve, to be sure, and we have no way to stop our health-care workers from getting infected in the community.”

“Its elements are all familiar: hygiene measures, screening, distancing, and masks.”

“The SARS-CoV-2 virus does not last long on cloth; viral counts drop ninety-nine per cent in three hours.”

“Toughing it out is now a shameful act of disloyalty.”

“Surgical masks are made of a melt-blown polypropylene fibre fabric, which, under magnification, looks like cotton candy. Most of the filtration this material provides isn’t from direct blockage but from an electrostatic charge applied to the fibre using a machine called, aptly enough, a corona charger. The static electricity captures viral particles the same way that a blanket in the dryer catches socks. This allows the material to breathe more freely. Cloth masks feel warm and smothering by comparison, and people tend to loosen them, wear them below their noses, or take them off more frequently. The fit of improvised masks is also more variable and typically much worse. A comparison study found that surgical masks did three times better than homemade masks at blocking outward transmission of respiratory viruses.”

I also enjoyed the following link on the value of face masks. The comments on this are indicative of how a strong, well organized contingent in the US is arguing against masks.

As before, Vivian Ho’s weekly  blog is full of many great links. Including recent work by Erin Bromage.

May 16, 2020 New Favorite overview of the Dance challenges

Way back on March 29 I recommended Tomas Puyea EXCELLENT, clairvoyant article

Coronavirus: The Hammer and The Dance (29 minutes).

That article is foundational and is still be essential reading for everyone.

I have been remiss in not revisiting and following Puyea’s subsequent work, which contains an excellent Learning How to Dance series. He has just released Part 5. I recommend all of them, although there is some overlap, as there should be in any “Learning how to…” series.

Part 1: Coronavirus: Learning How to Dance (19 minutes)

Part 2: Coronavirus: The Basic Dance Steps Everybody Can Follow (18 minutes)

Part 3: Coronavirus: How to Do Testing and Contact Tracing (39 minutes)

Part 4: (not yet published)

Part 5: Coronavirus: Prevent Seeding and Spreading (31 minutes)

Key insights from all of this:

We should particularly avoid allowing very large gatherings such as sporting events, conconcerts, crowded churches, restaurants with no spacing, because these  are the worst hazards to the Dance.

Several countries have successfully quashed the infections, but will have to continue to restrict outside visitors and even regional travel.

Some countries and some US states have taken few precautions and will end up needing to get to herd immunity to stop the spread. This will take about two thirds of the population getting ill before infections quiet down, at a fatality rate of .5 to 1.5 this would kill 1 to 3 million Americans. there are many excellent figures and simulations that highlight all that can be done without totally closing down the economy

28 percent of infected people infect their spouses, 14% infect other people they live with, and 4% infect their children. Social distancing within the household is very challenging.

Opening schools while managing interactions to be only among smaller groups and having monitoring is proving successful in many countries.

South Korea never really shut down, but has extraordinary public effort, public information and intrusive quarantining.

International and even regional travel will likely have to be restricted for a very long time, such as until an effective vaccine.

There is still no guarantee that a vaccine or immunity will be effective for more than two years.

My own thoughts to add: There is very little in Puyeas work about the role of weather. Colder, drier areas do seem to have greater exposure.

I see a great need to highlight that even vacation travelers can stay in hotels and summer rental housing if they are willing to leave an interval of 3-4 days between guests.  Similarly mail, store purchases, and food, that has not been touched for a few days is inherently safe. Things stored outside in UV light including picnic tables and benches and rocks and trees are also extremely low risk because of this natural healing.

The findings discussed in Erin Bromage (see May 11 blog summary below) that only 0.3 percent of all infections have been traced back to someone getting infected outdoors speaks volumes to me.

We will have to give up not only handshaking, but also hugs, social kisses, and close encounters among family and friends. Italian and Spanish traditions, young people in clubs and others who believe in extensive close social contacting will need to change.

The latest antibody test in the city of Boston found that about ten percent of the population has been infected so far. So Boston is about 1/7th of the way to herd immunity.

COVID-19 antibody test results from Santa Clara (1.5% of population testing positive), and from Denmark (1.8%) taking antibody tests of random samples find that overall infections are approximately uniform by age. Children are just as likely be become infected as adults, but they are much less likely to show symptoms or become highly contagious.

Future costs of all the medical complications of people who recover from COVID could be very serious.

I can’t resist including an extended quote describing Taiwan’s response to COVID in March. This is taken from Part 1. All highlights were in the original article.  They have only had ~500 cases and 46 deaths so far. Population is 24 million, more than New York State (19 million). Enjoy.

“Taiwan’s level of preparedness is jaw-dropping. This is a list of over 100 measures they took before March. Here are some examples, from the list and other sources:

  • Early and strict travel bans, updated every day.
  • They centralized the management of mask production, starting at 2.4 million per day (twice their need of 1.3 million at the time).
  • They set the price to avoid profiteering, initially at USD $0.50 per mask.
  • The penalty for price gouging for masks and other key items became 1–7 years in jail and a fine up to USD $167,000.
  • The spread of fake news could be fined with USD $100,000.
  • Proactive detection of cases: They tested all people who had previously had flu symptoms but tested negative for flu, finding some coronavirus patients.

All of the above happened BEFORE Wuhan even shut down! Then, they continued:

  • Soldiers were mobilized to produce masks.
  • The official price of masks was eventually down to ~$0.20 by the end of February.
  • Eventually, they ramped up production to 10 million masks per day (for a population of 23 million) before the end of March. Masks were rationed and their export banned.
  • Travel and healthcare databases were connected, so healthcare professionals could know who was at a higher risk of being infected. The Taiwanese CDC could track what was happening on the field in real time.
  • It triaged travelers based on their risk, from free to enter the country with self-monitoring to mandated quarantines.
  • Quarantine support with food and encouragement.
  • Enforcement of the quarantine through people’s existing phone signals. If they don’t have a phone, the government provides them with one. An alert is sent to the authorities if the handset is turned off for more than 15 minutes.
  • Persons who were not compliant with home quarantine orders were turned over to law enforcement and tracked by police officers. A couple was fined USD $10,000 for breaking the 14-day home quarantine rule.

If the world was a class and each country was a student passing a coronavirus exam, Taiwan is acing the test. And it’s offering to help. If I were another student, I would take that offer.

That it for now.

May 11, 2020 Hot off the presses from U.Conn., MIT-Sloan Harvard, and collaborators

Weather Conditions and COVID-19 Transmission: Estimates and Projections

Ran Xu, Hazhir Rahmandad, Marichi Gupta, Catherine DiGennaro, Navid Ghaffarzadegan, Mohammad Jalali

The attached paper was just posted today on SSRN with coauthors from UConn, MIT-Sloan and Harvard. It has over-the-top modeling of daily data from every county in the US, plus cities, states or countries worldwide rates of COVID-19 infection based on weather, humidity, air pressure, geography, wind, sunlight, and even the phases of the moon! (This last one has to be considered the werewolf effect, which they omitted from their final model even though statistically significant.) I saw the write up about it in the Boston Globe yesterday but the actual paper was only posted on May 11.

https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3593879

They do not forecast rates of disease but only relative rates of infectiousness and how they are affected by weather. They have only a few months of data from a wide range of worldwide cities.

They have a really cool graphics generated here, including the ability to generate weekly forecasts of relative rates of infectiiousness by city, county state and country worldwide. You can play with it to look at patterns by state, simulated by week across the year.

https://projects.iq.harvard.edu/covid19/us-counties

They get that favorable weather can reduce rates of infection by about 40 percent, or worsen it by about the same. Given that the rate is about 2 overall, then this means it will slow down in many parts of the US this summer, but then come back strong next fall or winter. It is worse in cold, dry areas.

 

May 11, 2020 Best overview of COVID infectiousness

I have read a lot of articles about COVID, but this paper, by a professor of biology of U Mass Dartmouth, is  the best so far at signalling how different activities and situations vary in their riskiness. I recommend it highly to everyone.

The Risks – Know Them – Avoid Them, by Erin S. Bromage, Ph.D.,

The paper emphasizes

Successful Infection = Exposure to Virus x Time.

Shopping in an uncrowded large store for a short time is relatively safe, as is jogging and brief contact while social distancing. In contrast indoor in-person meetings, especially in small areas, parties, church gatherings, concerts or other large gatherings, or other events that last for an hour or more and include talking, singing, eating, exercising, or touching shared items are the most risky.

Here is the direct link. It is a 12 minute read. Do it now!

I especially like that this article is by an ordinary professor, who has just done an extraordinary synthesis of German case studies, epidemiology and other diverse scientific sources. It highlights that all of us can play a role in fighting this virus.

Also, I also recommend this article by the same author, which covers events in China, the origins of the virus, and descriptions of various tests and vaccines.

Where We Are Now

https://www.erinbromage.com/post/where-we-are-now

About the author:

Erin S. Bromage, Ph.D., is an Associate Professor of Biology at the University of Massachusetts Dartmouth. Dr. Bromage graduated from the School of Veterinary and Biomedical Sciences James Cook University, Australia where his research focused on the epidemiology of, and immunity to, infectious disease in animals.

May 9, 2020 Good signs.

Today (Saturday) I ventured out out to a local hardware store to get a few gardening items and to CVS to pick up a few health items. Among the many encouraging signs were:

  • Everyone I saw in either place was wearing a mask,
  • Social distancing was marked on the floor and adhered to.
  • CVS was actually selling nursing quality masks (not N95, but at least with metal strips around the nose) for $2 apiece, limit of 4
  • The hardware store was selling hand sanitizer and bulk packages of 100 gloves at a normal price.
  • Everyone was friendly and happy.

There is hope for a more pleasant existence in our future together, even if things will remain different for a while now. Keep your hopes up!

May 8, 2020 Careful statistical model of COVID-19 fatality rates

Anirban Basu, an exceptional econometrician (with 9252 Google Scholar citations) at the University of Washington who is personally known to me, published an article that just appeared in Health Affairs yesterday.

Estimating The Infection Fatality Rate Among Symptomatic COVID-19 Cases In The United States

Using daily county-level data on deaths and new cases from the US up through April 20, 2020, he estimates Bayesian models of the infection fatality rate among symptomatic cases (IFR-S) which give a point estimate of 1.3% of all people with COVID-19 symptoms dying.

The Health Affairs article is heavy reading for a non-statistician. To give you a flavor, here is the key sentence about methodology: “The mean of this Binomial model, p_jt, represents the probability of death, and is expressed as a Bayesian random-coefficients exponential decay model within a logit link framework so that the predicted rates remain within 0 and 1.”

Here are the first few sentences from the abstract.

“ABSTRACT: Knowing the infection fatality rate (IFR) of SARS-CoV andSARS-CoV-2 infections is essential for the fight against the COVID-19 pandemic. Using data through April 20, 2020, we fit a statistical model to COVID-19 case fatality rates over time at the US county level to estimate the COVID-19 IFR among symptomatic cases (IFR-S) as time goes to infinity. The IFR-S in the US was estimated to be 1.3% (95% central credible interval: 0.6% to 2.1%). County-specific rates varied from 0.5% to3.6%. The overall IFR for COVID-19 should be lower when we account for cases that remain and recover without symptoms.”

This segment was also highly informative to me.

“Results from sero-testing from the Diamond Princess outbreak suggests that about 17.9% of infected persons never developed symptoms.10 Consequently, a reasonable estimate of the overall IFR would be about 20% lower than our estimated IFR-S.”

In the conclusion:

“If we carry out a thought experiment where 35.5 million individuals would contract COVID-19 illness this year in the US (i.e., the same number as flu last year)19 then, in the absence of any mitigation strategies or social distancing behaviors and the supply of health care services under typical conditions, our IFR-S estimate predicts that there would have been nearly 500,000 COVID-19 deaths this year. To the extent that COVID-19 is more infectious than flu and does not have any protection from a vaccine or treatment, the number of infections, and hence the number of deaths, would be higher. Certainly, with mitigation strategies, the death toll will be lower.”

My interpretation: The paper is very open about biases upward and downward. One bias not discussed is the number of deaths unreported in the data, which now appears to be significant. Death rates in the US are likely to be higher than in other countries, for many of the reasons discussed in the Boston Globe article linked here. Still, these are very sobering numbers for the US.

Here are a few key sentences (with cites) from the article that resonate with me.

Ninety four percent of deaths from COVID-19 are in those with an underlying age-related chronic disease, mostly caused by excess body fat.

“Only about 12 percent of Americans are metabolically healthy, without a large waist, high blood pressure, high blood sugar, or high cholesterol.”

“The sad reality is that 75 percent of Americans are overweight, and more than 42 percent are obese. Chronic disease affects 6 out of 10 Americans. Also 20 percent of normal-weight people have prediabetes. These shocking rates of poor metabolic health — with nearly 9 out of 10 American adults unhealthy — is a major reason the COVID-19 crisis is so much greater than it needs to be.”

My interpretation: Just like a marathon race, winning against the coronavirus requires a strong immunity system, strong lungs, and a healthy heart. Americans, and particularly poor Americans, are compromised in all three with their diet, lifestyle and environment more than the rest of the world. I invite you to read the article.

Fortunately, for many of us with increased free time, the inconvenience of buying large quantities of food, and greater motivation, now is a good time to do something about it.

As May begins, stay-at-home orders end

Governors of coastal states including California and Florida have faced particular pressure as they try to balance health concerns with growing demands for beach access as the weather heats up. Here’s a map of the varying restrictions across the U.S.

Gov. Gretchen Whitmer of Michigan reinstated a state of emergency on Thursday, even as protesters, some of them legally armed, gathered at the State Capitol.

Here are the latest updates from the U.S. and around the world, as well as maps of the pandemic.

For a detailed picture of the outbreak in the U.S., we’ve also compiled data from hundreds of metro areas.

May 1, 2020. Pessimistic forecast from Yahoo Finance, and my own thoughts.

Here is an insightful interview with El Erian on the monetary and fiscal responses to COVID-19:
https://finance.yahoo.com/video/el-erian-worst-recession-since-154048623.html

His statements accord with my view. Pretty grim.

The most telling thing to me is the lack of confidence and incredibly negative consumer expectations. People are only buying necessities, and that will not fuel the economy. Even food production (meat, fresh vegetables) is now uncertain. On April 10, a poll of sports fans found that 72% would not plan to go to a sporting event even if they resume in September. (What about children in schools or universities or any public entertainment, or restaurants?) Even the workers getting government aid want to save it since they realistically fear that the worst is yet to come. The ridiculous epidemiological model from U. Washington predicting a nice bell-shaped declines in rates of infection with the shutdown are not even close to the persisting rates of new cases, and the very gradual, flat persistence. Deaths are being grossly undercounted, and we are still less than 10% of the way toward herd immunity. Reopening the economy fully will I believe likely cause many areas to overload their hospital capacity in about three weeks: the average time from new infections to death (two to three weeks) plus a week for a renewed doubling in cases because we still have high fundamental infection rates to start from.

I am not a macro economist, but we now have a shock where earned income has dropped about 40% (Ellis and Marcolongo, April 17, 2020, with a new draft out next week), and more in the most vulnerable occupations. Current PPP loans are not reaching the neediest, and $1200 per person will not last long. Cities and states will soon be going bankrupt and start having to lay off public workers unless the federal government acts very quickly, which they can’t. Even people who have income, like me, are perhaps spending less than half of what they would usually spend, hording food, but not spending anything on travel, transportation, other consumables or durable goods. We are just spending more on personal delivery services and internet services. Health care spending will be strong, however, given the resources spent on COVID, but offset by canceling most elective and preventive care. I can easily see a more than 50% decline in consumption spending in the economy. Something similar is happening in the rest of the world, plus trade is also collapsing. I don’t see why the stock market is still acting like we will come out of this quickly. (Remember, the Dow Jones lost 75% of its value in the Great Depression. We are a long way from that now.) The economy is so dreary that I have pretty much stopped blogging about my predictions in the last week.

I am enjoying bird photography, vegetable gardening, and baking bread. I recommend these activities highly to you. It is nice to fall asleep thinking about gardening or how to zoom about birds instead of about COVID-19.

The state of Maine started reopening as of today. Lets see what happens.

Have a good weekend!

April 23, 2020 Science article about COVID-19 effects

This Science article has an excellent overview about the complex medical challenges from COVID-19.

I recommend it to anyone interested in clinical manifestations, rather than economics or epidemiology.

How does coronavirus kill? Clinicians trace a ferocious rampage through the body, from brain to toes

April 22, 2020

The New York Times just updated their web site showing rates of reported COVID-19 cases and deaths by country, state, and city (MSA) which is updated daily. This is my go-to location for up to date rates. They are now using the most recent week of data (versus five days, previously) and recentered all their plots to start when a country or state had 200 cases (or 100 deaths) instead of ten.

There is an excellent overview of sources by Vivian Ho, Kirstin R.W. Matthews,  and Heidi Russell, from the Rice Baker Institute. I first learned about this from The Incidental Economist blog by Austin Frakt. I recommend you choose which sources you want to review for your update.

One anecdote reflecting my own experience is revealing:

Yesterday I spoke for 20 minutes with someone working closely with an estate attorney.  Several things surprised me. This person (“Jane”) said that the lawyer in the Boston area was swamped by demands for living wills and do not resuscitate (DNR) orders (covering what to do when faced with the choice of being on a ventilator, for instance), updated wills, trust tax forms (no extension granted for these) and particularly assistance to households trying to get death certificates from the state.

Jane revealed two nursing homes in the area that have not yet gone public with the surge of deaths they have experienced because of fears over negative publicity.

Jane spoke of  several people who died in nursing homes who were not yet reported to the state because when a death occurs at home or in a minimal care nursing home a death certificate requires verification by a coroner, and coroners are overwhelmed just now. The coroner must decide whether an autopsy is needed, and what samples should be taken before determining the cause of death. This is causing a serious delay.  This leads me to believe that deaths in total and deaths attributed to COVID are being understate in some places in the US, and that more reliable estimates will want to look at deaths by age this year versus over past years.

These unreported deaths are consistent with recent reports in the media about new tests of samples from deceased bodies are turning up new cases of SARS-COV-2 not previously recorded.

April 22, 2020 Nursing home rates skyrocket.

Yesterday, April 21, the Boston Globe published a site for Massachusetts nursing homes that reporting confirmed cases by named. Unfort6unately they only have three tiers: <10, 10-30, and 30 or more. The results are stunning. A total of 228 Nursing homes are reporting cases of COVID, out of 338 in the state (56%). The data is to granular to calculate

My own calculations using the Massachusetts nursing home data as of April 22, 2020 posted on the Boston Globe web site suggests that among those reporting at least one confirmed COVID case, the average rate of confirmed cases is 15% or more of all residents, much higher than the population averages reported for older age groups.

I commend the Massachusetts Department of Public Health for publicly posting its rates of testing, new cases, rate of hospitalization, and deaths each day. Rates by race and  place of death are reported. Also interesting is the detailed PPE supplied by region. Rates of N95/KN95 and other masks still seem distressingly low in the state.

I will mention that the number of COVID tests done per day has remained constant at approximately  5,000 since March 24, and that the very high positive test rate  – average of 26% over the past five days – suggests that there remains a very large number of infectious cases not being identified at existing test levels.

April 22, 2020 Humor and misinformation

I was trying to track down a legitimate post mentioned on Facebook and had reason to view a variety of Facebook sites ridiculous postings. Some of the claims so outrageous as being hilarious. Here is one of my favorites:

It will be extremely important for the truth about the events of September 11th, 2001 in New York to come out one day, including the truth about the use of a Directed Energy Weapon to “Dustify” the buildings. I hope and pray.”

I was originally going to post several more ridiculous claims. but they were gone!

When I went back to Facebook to copy them, they had been removed. Plus, in two cases, I saw notices from Facebook that they had fact checked some consumer posts, and inserted a link to discuss why certain key statements were false. Hallelujah! Great to have Facebook start actually policing postings and repostings for accuracy.

April 21, 2o20

I was forwarded an interesting article about hypoxia in the NY Times that is worth a read.

The Infection That’s Silently Killing Coronavirus Patients: This is what I learned during 10 days of treating Covid pneumonia at Bellevue Hospital. By April 20, 2020

It describes how COVID19 induces hypoxia and recommends the use of a pulse oximeter as a low-cost route to early identification of COVID pneumonia. One of the striking findings in the article is that the normal signal of breathing problems (a build-up of CO2) doesn’t happen with COVID-19, so that hypoxia can progress quite far, without the person realizing that anything is wrong – hence the value of proactive monitoring of blood oxygen levels.

Widespread pulse oximeter testing could be very significant for our ability to manage COVID-19 during the ‘dance’ phase, by changing the ratios at several important points:

  • Reduced R: Earlier detection of COVID19 cases through early identification of hypoxia, even before other symptoms have developed  has the potential to increase the ability to isolate earlier and reduce the infection rate.
  • Reduced % of cases needing ICU beds or ventilators. Earlier detection of hypoxia would allow more routine treatment and less need for oxygen or intensive care, reducing the pressure on ICU beds and on ventilators.  The NYT article suggests that better treatments alone – e.g., better positioning of the patient for better breathing could reduce ventilator need  in the first 24 hours by 75%.
  • Reduced mortality rate.  The NYT article doesn’t speak to this directly, but it is suggestive that a major reason for the high mortality rates for individuals without other underlying conditions is that the hypoxia has progressed to dangerous levels before seeking treatment.  If so, avoiding dangerous levels of hypoxia might dramatically reduce mortality rates for otherwise healthy individuals without underlying conditions.

April 20, 2020 Masks

The US continues to be woefully unprepared for the volume of personal protective equipment (PPE) needed and is still totally failing to keep up with the urgent need. Here is one telling quote from Dr Steve Corwin President and CEO of New York Presbyterian Hospital speaking to CNN on April 6, 2020:

“We can’t make that mistake again. I know the next crisis will be different than this one. But let me just give you a statistic, pre- crisis, we were using 4,000 masks a day of all sorts. Now we’re using 90,000 masks a day.

Given that there are 2650, staffed beds at NY Presbyterian, that implies 34 masks per bed per day. Official guidelines are for hospital workers to put on a new mask each time you enter a patient’s room, which is a lot of masks for each health care worker and each patient. Fortunately some areas have figured out how to sanitize and reuse some N95 masks, but the costs of doing this may exceed the costs of making a new mask, which with bulk production are fundamentally very inexpensive. The magnitude of the need is still unprecedented.

This following table calculates the magnitude of the mask problem for  New York state, Massachusetts, and the nation assuming the same rate of need as NY Presbyterian Hospital in early April, before the peak need in NYC.

NY Presbyterian hospital All New York state hospitals All Massachusetts hospitals  All US Hospitals
total staffed beds             2,650             53,000               15,193                924,107
masks per bed                  34                     34                      34                        34
masks per day         90,000      1,800,000            515,989         31,384,766
days per month                 30                  30                 30                       30
masks per month   2,700,000     54,000,000       15,479,660      941,542,981

Governor Cuomo has asked new York hospitals to add another 20,000 emergency beds, which increases the demand even more. These calculation suggest a need for more than a billion masks per month to meet the US hospital demand for masks.

Notice I am not talking about N95 masks, but “all sorts of mask”, just like Dr. Corwin. This calculation ignores the additional masks needed for dozens of other occupations (police, firefighters, public health, pubic transport, food workers, pharmacy workers, and other essential workers). Given their numbers, this easily adds another billion masks per month. Then there are ordinary citizens: if each citizen wanted to use new three masks per month, that would add another billion face masks.  These uses quickly triple the number demanded nationally: 3 billion masks per month, or 100 million masks per day.

These levels of demand would require a thousand plants each producing 3 million masks a month, just for serving the US. While a charity event like the Boston Patriots owner flying home 1 million masks from China that were shared between hospitals in NYC, Rhode Island, and Massachusetts, was helpful, achieving a day’s supply at best for the three regions, a much bigger concerted effort is needed. Masks are not expensive, this could be done for perhaps a billion dollars per month once scaled up. That is only $3 per American per month. We can do that.

Obviously a great deal of other PPE equipment is also needed. I need not make the calculations here.

We need the federal government to immediately use its emergency wartime powers to ensure that US industry is turned to producing these supplies at prodigious rates, not just rely in imports and voluntary private businesses to supply the need. After resisting the need for widespread mask wearing, it is time for the US to take this step before we consider partially reopening the economy.

THE EARLY TOLL OF COVID-19 ON JOB AND INCOME LOSSES: VULNERABILITY BY OCCUPATION

Randall P. Ellis and Giovanna Marcolongo

Key message: Early PPP funding does not target the occupations most affected by the COVID-19 shutdown

Figure 2 summarizes the key findings of a new poll of 13 labor and health economists from April 3 to April 10 conducted by the authors about rates of job and income loss of employees by occupation (including seasonal and less than full time workers).

Overall, we calculate that the two-month income losses from the pandemic are $485 billion and argue that the most impacted occupations may be least able to benefit from the PPP loan program.

April 14, 2020 Herd immunity

Jeff Howe from the Boston Globe on April 11, 2020 summarized Harvard epidemiologist Marc Lipsitch modeling in a very direct, if unpleasant way. It is worth a read if you want to know what a top epidemiologist thinks.

The only way this ends: herd immunity

“This is the simple, scary math that Harvard epidemiologists Marc Lipsitch and his colleague Yonatan Grad have tried to convey in a series of recently published papers: If each person infected with COVID-19 disease in turn infects three more, as we now think, then in order to bring the disease to heel, Grad says, two of those people must already be immune.”

Currently we are hunkering down with less than 3% of people ever infected everywhere.

The figures in the Boston Globe article are easier to interpret than the three linked academic papers. Worth a sobering read if you care to.

This opinion piece by Marc Lipsitch in the NYTimes on 4/13/2020 is on a similar vein, and also presents evidence on how well people acquire immunity from exposure. Immunity appears not to be complete but only 80 – 90%.

My own belief is that the epidemiologists are perhaps too pessimistic about the assumption and implications. My reading is that good masks (see earlier posts below on Stanford study) reduce infection rates by 70 to 95%, so if everyone wore masks routinely, and also washed hands regularly, the infection rate need not multiply as rapidly as modeled for much of the population, which they max out at a 60% reduction. This points to the importance of high quality, comfortable and hence widely worn, personal protective equipment (PPE).

The biggest short run hope is not vaccination, but PPE, physical distancing, crowd avoidance, and above all effective palliative and treatment drugs so that the infectiousness and death rates can be brought way down. As an analogy, we have never found a fully effective vaccine for malaria, and malaria is still a potential risk even in the US (and Spain and Italy), but we now have very effective prevention methods and treatments for it, so that rates of reinfection are low here and deaths and serious cases rare. The Jeff Howe 4/11 Boston Globe article mentions that 40 different drugs have been approved for clinical trials in the US. These are treatment drugs, not vaccines. If at least one of them is highly effective, then we would free up a lot of ICU beds, reduce pain and deaths, a make us all a lot less fearful of the disease.  By focusing on already existing drugs, we have a much better chance of one becoming available sooner. This give me hope, because the infection simulations and impacts on the economy do not look good without this.

Also giving me hope is that several health economists are coming out with behavioral models that may do a better job at building in feedback loops than the existing epidemiological models that I have seen.

April 11, 2020 Birdwatching in Newton

Today my wife and I took our dog for a walk at Brayburn Country club and saw eighteen species of birds. Most notable were a pair of bluebirds, a pair of green-winged teal, and two magnificent male wood ducks.  Also seen today were turkey vulture, red-tailed hawk, mallard ducks, Canadian geese, chipping sparrow, house sparrow, grackle, starling, mourning dove, chickadee, robin, goldfinch, white-breasted nuthatch, red-bellied woodpecker, chestnut-sided warbler, and at our feeder pine warbler, two turkeys, (including a Tom on full display), cardinal, junco, blue jay, house finch, gray squirrel, and chipmunk.   Fun to see 20+ species on a casual day near home. Our winter viewings since COVID-19 quarantine is now 36 species.

April 10, 2020 Happy Holidays to all!

I pass along the holiday greetings of my friend Shuli Brammli of Israel

Dear Friends,

This week we are entering a period when the three religions are celebrating their spring holidays. One by one we celebrate Passover, followed by Easter and then by Ramadan Kareem of our brothers the Muslims. We don’t know much yet about the consequence of this Epidemic that we all experience. But one fact is undeniable. We all live in one small world and there is no other world for us. It is too small to be ignored. I hope that we will be smart enough to learn the lesson from this, and that we will be kinder to each other and compassionate, promote social support and mutual guarantee within our society as well as between our countries. I wish you all the best for you and your beloved ones.

Happy holidays

April 10, 2020 More on job impacts of COVID pandemic

There is an important article by Noam Levy at the LA Times that is worth a careful read.

Coronavirus already changing medical care in the U.S.

Here are a few sentences.

“Primary care doctors have seen a big uptick in telehealth visits — a move widely hailed by public health experts. However, the fees for these services are often lower than for office visits. Many physician practices have seen in-person patient visits drop 50% or even 75%. That has left physicians struggling to stay afloat and forced growing numbers to consider laying off staff or even closing their doors. Nearly 8 in 10 primary care clinicians in one recent survey reported their practice is under “severe” or “close to severe” strain due to COVID-19, the disease caused by the coronavirus.

Stunning survey results from a Seton Hall Sports Poll conducted on Thursday.

Vast majority of Americans would not attend games without coronavirus vaccine, poll says

Seventy-two percent of Americans said they would stay away from a sports event if it were held before a vaccine is developed. Even if the seating arrangements allowed for social distancing, just 12 percent would be comfortable with that setup.

Also revealing was yesterday’s Boston Globe report on tech industries in Massachusetts.

More job cuts hit Boston’s tech sector as coronavirus effects spread

A few selected quotes.

“Toast, the maker of popular software and systems used by the restaurant industry, said late Tuesday that it was laying off over 1,000 employees, reducing its workforce by about half through layoffs and furloughs. The company said that restaurant revenues have declined by 80 percent since state and local officials began shutting down businesses nationwide, and “our success is tightly coupled with the success of the restaurant industry.”

Lola.com, Zipcar, Hopper, and Wanderu have all cut back workers as travel restrictions have decimated the industry. At Logan Airport, the number of passengers fell by 93 percent between March 23 and 29, compared to the same period last year, according to the latest Massport data.”

This NY Times article on inequality also speaks to the huge inequality of burdens.

April 8, 2020 JAMA Network Open paper published!

Although tangential to this COVID blog, the big news for me on April 8 was the appearance of my first first-authored paper in JAMA. It is worth a click if you understand the importance of disease tracking over time.

JAMA Network Open  (Open means it is free to all viewers)

Answer: YES. See the paper’s figures to see how much.

It has been a long time coming, but here it is! We didn’t like the title either, but JAMA insisted. This is the first publication from our ICD10 project. We use 1.2 billion data points for the figures, which are the best thing to look at.

April 6, 2020 pets can get infected

There is now significant evidence that pets, such as dogs and cats can become infected with SARS-CoV-2, however no evidence yet over whether they can infect humans through the air. But it seems likely. Here is the evidence from the American Veterinary Medical Association (AVMA). I personally will not stop petting our dog, and will consider her part of the family who is at risk of exposure if any of us become ill. We no longer let her get close to any other dogs or people, so she is like other members of our family.

April 6, 2020. How to sanitize masks against viruses.

The link on the previous posting from Stanford includes advice for achieving medical quality sterilizatoin of N95 masks. Here is the key table.

Their key finding is don’t use bleach or alcohol to sterilize masks since it can change how well they filter or the difficulty breathing. heating anything in an oven to 160 for 30 minutes will kill the virus.

My reading is that for cloth masks, where you want adequate but not surgical safety, any of the following should work

Running them through a load of wash, where the soap will remove the germs to practical levels.

Put them in a dryer at high temperature for ten minutes.

Put in hot or boiling (not recommended for many rubber or stretchy attachments, however).

Leaving things out in the direct sun for a half hour works because of UV light.

Or leaving them unused for a five days will also kill COVID germs (but not necessarily other germs).

The other key advice is not to reuse or handle used masks. Treat them as if they are used tissues. If you have been around anyone who is infectious, and your mask has done its job and filtered/caught any bad germs, then you don’t want to be touching the germs or reattaching them to your face. best is to have several and just routinely use a different one once you have been out with one.

April 6, 2020 Sewing your own fabric mask from the NY Times

This requires having a sewing machine to make several well.You probably have a friend or neighbor happy to give or sell you one for a donation to a good cause.

In a pinch, the following simple technique could also be  effective if bulkier in areas where it is not too hot.

Find a 100% cotton T-shirt and a black binder clip. Put the whole T-shirt over your head and use the binder clip (or a safety pin) to shrink the size of the head hole to be snug around your nose and mouth, leaving the rest of the shirt just hanging around your neck. When done visiting the store, throw shirt in a plastic bag, wash your hands, and be sure to launder the t shirt before the next use.  Keep several T-shirts handy.

Any face mask will only work if you actually wear it… Half (?) of its effectiveness is probably from the reduced ability to touch your mouth and nose. Wear glasses or goggles to also reduce eye touching.

April 4, 2020

The media is full of predictions of the date on which rates of hospitalizations, and deaths will peak. Many of them are informed by the model from IHME, the Institute for Health Metrics and Evaluation, which is led by Christopher Murray, a well regarded health economist and MD, now an adjunct professor at the University of Washington. He is best known for his work calculating the burdens of disease for WHO and the World Bank. IHME are updating their predictions for COVID-19 every few days.

COVID-19 projections assuming full social distancing through May 2020

There is a research paper in draft form linked here.

I think this comment below on that paper sums up well the weaknesses of this method. Murray uses a simple parametric model, and assumes that the rate of new infections will be a symmetric Gaussian sigmoid function. There is no evidence that the decline will be symmetric with the rise, and indeed the evidence from South Korea is that it does not return to a zero rate, but rather to a low, but still growing rate of growth. So I do not place a lot of faith in the predictions other than that in the short term we are in for some very difficult times. States that started lock down earlier will face less exposure. Those that have yet to start, could be in for a much higher mortality. For reasons discussed below, I do not believe the China rates of extremely low deaths recently are entirely reliable. There is reason to believe that they have been concealing deaths.

 

 

While it is easy to be critical, no one really knows what the right hand tail will look like, and I do not know any other model that is worried about short term forecasts as much as this one.

The bottom line of their model, as of today 3/4/2020 at 12:49 pm EST is that they forecast that the US hospital bed demand will peak on April 15, 2020

Resources needed for COVID-19 patients on peak date

All beds needed: 262,092beds  implying a Bed shortage of 87,674 beds

ICU beds needed: 39,727beds implying an ICU bed shortage of 19,863beds

Invasive ventilators needed: 31,782 ventilators

He forecasts that the number of deaths will peak one day later at 2,644 per day. With eventual deaths by August 4 of 93,531.

At his last update three days ago, he raised his estimated beds needed and deaths. the web site says that it will be updating its model and predictions today, April 4.

 

April 4, 2020

It is only a newspaper report, but the 3/4/2020 Boston Globe had an interesting article about funerals in China, which has been receiving some attention. China is making it hard to attend an count deaths through this normal means. So people have been using other methods.

 

https://www.bostonglobe.com/news/world/2020/04/03/china-curtails-memorials-during-tomb-sweeping-festival/QUBuvZg0jVntNTk9SqcQGO/story.html

 

Below is the relevant text to me. Two different estimation techniques both give much higher estimates of death. Note that the current death count in China is still only 3,326. Only slightly more than Iran, another country that people question: how could they be so successful?

“Long lines have been forming at funeral homes in Wuhan over the past two weeks, as family members have been informed they may collect their loved ones’ remains ahead of Tomb-Sweeping Day. Some waited six hours to collect an urn, then the ashes.

The Hankou Funeral Parlor’s crematorium was operating 19 hours a day, with male staff enlisted to help carry bodies. In just two days, the home received 5,000 urns, the magazine Caixin reported.

Using photos posted online, social media sleuths have estimated that Wuhan funeral homes had returned 3,500 urns a day since March 23. That would imply a death toll in Wuhan of about 42,000 — or 16 times the official number. Another widely shared calculation, based on Wuhan’s 84 furnaces running nonstop and each cremation taking an hour, put the death toll at 46,800.

Wuhan residents say the activities belie the official statistics. ‘‘It can’t be right . . . because the incinerators have been working round the clock, so how can so few people have died?’’ a man, identified only by his surname of Zhang, told Radio Free Asia.

US intelligence agencies have reportedly concluded that China’s numbers are much lower than they are in reality.”

Let me note that these reports on urns and cremations might also be biased, reflecting misinformation. I won’t speculate on how or why.

I myself look at South Korea as the country most likely to have a reasonable trend. They are showing a reduction to less than new 100 cases a day, with deaths hovering around 10 per day. Even scaled up for the US, that is a level that buys us time until we get a virus. That seems credible to me.

Yesterday was a day of much bad news. First an Italian colleague and health economist stated and provided further support today, that there is evidence from Italy that health care workers who are believed to have had COVID and recovered, have become reinfected and showing new symptoms. This was also supported by news in the NY Times (source not provided) of reports coming in from Wuhan that an estimated 5-10 percent of people are becoming reinfected with the virus, after seemingly recovering.

The other bad news is that the articles in today’s papers that the current COVID test used for current infections appears to have a 30% false negative rate. This is really bad because it means that after testing and sending people home, 30% may still have COVID.

More bad news is that two people I spoke with in our summer town in Maine thought that the presidents financial stimulus would not be of any value to them, for different reasons. So as I have worried, the very lowest income citizens may not be helped meaningfully by the measures taken to date.

My own “back of the envelope” calculations using my own guesses about rates of job loss and lost income suggest that US income during the shutdown may have fallen by 40%, with an even larger drop in spending. This is unheard of in previous recessions.

John Burn-Murdock has been generating a series of excellent figures on COVID trends by country. There is a rich set in this series of Twitter feeds today. I recommend them to you.

This confirms what others have said, that there is no relation of infection rates to size of population across countries, at least for the low rates now. Ultimately population size will matter, but recall that even in the three countries with the highest rate of infections (Italy, Spain and Switzerland), the rate is only just over 150 per 100,000 which is .15%. So the saturation that slows down the rates of growth is not yet in effect. The US rate is only 39 per 100,000, which is .039%.

It is not the absolute levels that should make us scared but rather their rates of growth. If they double every 3 days, then in 30 days they will have doubled ten times and 2^10=1024. Multiply the above percentages by 1000 twice and you have everyone infected. Burn-Murdochs figures show no slowing down by population size, only by actions taken in some countries.

March 30, 2020

In case any readers are interested in doing your own empirical analysis of county rates of infectoin with COVID, the NYT might pick up if well done, they have just posted their entire dataset of county level cases and deaths from January 21 to at least March 29, 2020. Look here.

An article describing what has been posted is linked here.

Others have documented states and cities who have implemented guidelines and lockdowns. There are dozens of papers eventually to be written about all of this information.

These New York Times interactive figures and interpretation from today’s Upshot are excellent.

It is clear that Korea and China have done something critical by slowing the doubling rate to once per month or less.

The US is now the laggard. But the disease always spreads faster when entering a new area and rates are low. So what will matter is how they look in areas where there has been time to respond. In a few states there is encouraging news in that the rate of doubling has slowed down to about once every month instead of every two days in the worst cases.

I want to retract some of my enthusiasm in light of a link from a BU colleague.

https://blogs.sciencemag.org/pipeline/archives/2020/03/29/more-on-cloroquine-azithromycin-and-on-dr-raoult

While the news is on a larger sample of N-80, an article in today’s Science Magazine questions the reliability of the finding. It is still not a randomized controlled trial, and was done on a sample with a median age of 54, where a lower complication rate would be expected anyway.

My previous post is below.

There is also a key literature on the effects of hospital strikes on mortality. Cancelling all elective procedures and non-urgent care for COVID is a similar impact to a MD strike. This study from 2008 did a meta analysis of 156 studies of strikes from around the world, of which only 7 studies were considered high quality. These seven suggest that in every case an MD strike in the short run resulted in the same or lower overall mortality. They acknowledge that this is only the short run effect. But the cancellation of elective surgeries in the developed world tends to reduce other causes of death in the short run. Hard to build into models, but very real. Assuming zero or small negative change in the short run seems credible. More than a few weeks, who knows.

Wearing mask also helps us to dance well in the long run before we all can get effective vaccine. I’m glad to see more articles about wearing masks these days:

Everyone should be wearing masks when out of the home or around people at home who might be infected. Most of the west has been in error about not advocating their use.  Here is a good video.

The best source of up to date statistics I have found on COVID19 is WorldoMeter.info/coronavirus.

I visit it daily.

In WorldoMeter, I especially recommend the figures using the log scale on the vertical axis, so that you can quickly calculate the days before doubling or sadly the days before a ten fold increase.

As of March 27, the World is doubling every six days in terms of cases and deaths, while the US is doubling every 3.5 days. If this pattern continued for two months (60 days), then the cases and deaths from  COVID19 in the US would exceed the US’s population. If we slow down to the world rate of increase the US rate would still increase by the multiple 2^10 = 1024. If the US continued at this rate, every American would be infected in 60 days (A 32,000 multiple). If we assume the US only slows down to the current world rate then the following numbers emerge. This is not a prediction, only a calculation.

 

World USA
Doubling time (T) in last week 6 days 3.5 days
Times doubled in 60 days (50/T) 10
Multiple after 60 days (2^(60/T))                                  1,024
today 60 days Today 60 Days
cumulative cases   596,366   610,678,784        104,126      106,625,024
cumulative deaths     27,345     28,001,280             1,696           1,736,704
Calculations based on extrapolating most recent growth paths for 60 days
Source: Worldometer

In all of World War II, there were only 405,000 American deaths.

For President Trump to assert that the worst is over and that we should reopen everything on Easter would be equivalent to announcing that WW II was over two months after the US entered the war.

There has been a lot of misinformation about how seasonal COVID19 is likely to be. We have no prior information, so many are looking to the seasonality of Influenza (the flu). But more informative may be that of pneumonia, since COVID mostly causes lower respiratory infections (pneumonia), not upper respiratory ones, like the flu. Some work I am doing with a team has looked at monthly diseases rates per 10,000 people on 1.2 billion US monthly observations. These four pictures tell an important story.

flu1

flu2

If it were in our data, COVID would likely be classified into this CCS disease category and are likely to have similar seasonality.

flu3

flu4

Age patterns of prior high cost pneumonia cases also display a pattern similar to COVID, and seasonality by age would be possible with our very large datasets. The following figure is based on old data, and shows rates per 100,000 people. Something similar could be done with our newer data. It would be even more interesting with All Payer Claims data, which we hope to have available for a sample of states already. Notice that older Americans have much higher rates of treated infection, and this is much more likely to be high cost when they are infected.

Boston Bird Bingo

I took time to make the following game board because I greatly love bird-watching and also love games. I invite you to view it. School teachers or parents might enjoy it as well.

Boston Bird Bingo

I admit that our bird-watching is much better through having a bird-feeder in the back yard, which accounts for probably half of the species we have seen.

 

Each picture is of a bird or animal seen, heard or smelled in Newton  Massachusetts in March 2020.

 

Options:

  • Study it to learn the local birds and common mammals.
  • Print it out and see if you can see five in a row, column or diagonal.
  • See how many species you can see, hear or smell.
  • Click on the links to listen to the sounds, and then listen for them outside.
  • Print out the second page and see how many names you can remember.
  • Have someone tell you a name, and see if you can find it on the second page.
  • Try taking your own pictures or make your own recordings.
  • Learn the differences between male and female books. Look at the Cardinals! How different is the male and female house sparrow? Which one is shown here?
  • Use the embedded sounds to listen and learn, and then have someone else play them to see if you can identify them. How many can you guess correctly?
  • If you play all of the sounds quickly in sequence and on a recurring loop, you can turn your room into a bird sanctuary with all the sounds going at once. See if you can recognize them as they a sung.
  • These are mostly winter and year round birds just now. Soon arriving will be many migrants, including the red-wing blackbirds, kinglets, flycatchers, warblers, owls, hawks, ducks and geese. Then come the summer resident birds. See how many you can find on your own!
  • I have personally seen 15 wild mammals in Newton MA. Can you think of what they might have been?
  • Start your own life lists!

My new COVID19 mantra of March 28, 2020:

Stay at home.

If needed, send out one person every three days to buy food. Wear a mask if you go out. It need not be perfect, but any mask or scarf is better than nothing when around other people.

Maintain 2 meter distance if you do go outside. Jogging is fine.

Wash hands and things you touch compulsively. Wear gloves of any kind when you go out to stores.

Stay connected online to stay socially connected. Don’t watch too many news broadcasts.

This at home quarantine may only have to last for two months if we continue the dance well.

Low cost antibody testing kits are rapidly becoming available and will greatly help the dance.

Winter reading 2020

I started listening to Audiobooks while commuting, which lets me get in at least 45 minutes of audio listening a day during my round trip commute, which is wonderful.

My most recent favorites are

Talking to Strangers: What We Should Know About the People We Don’t Know. Malcolm Gladwell. 2019. Just as I have loved Blink, Outliers and The Tipping Point, I really like this book. Gladwell makes his discussion so vivid with lots of concrete examples. I have actually been enjoying the free Audiobook version, which is free to you if you have not yet downloaded the Audible app. The audiobook has recordings from actual police stops and court proceedings that make it incredibly interesting. Along the way you will appreciate differences by race, sex, foreigners, law officials, liars, cheaters, and above all understand people and make better decisions. 10/10

So you want to talk about race. Ijeaoma Oluo. 2018. I was inspired to read this book on systematic racism in the US by Austin Frakt’s Incidental Economist blogs about it. I was delighted with the Audiobook reading of it which was both deep and easy to follow. It will make you feel uncomfortable, particularly if like me you are a white, high-income male of privilege. I feel like I learned a lot, even if it is hard to change even a little. The image of blacks walking around and getting a constant series of “punch in the arms” from systemic racism is something that will stick with me and perhaps help me pause to try to recognize and minimize the many “mini-aggressions” that she documents so well. Low-cost paper copies are here. I rate it 9.5/10

 The Silent Patient. Alex Michaelides. This bestseller is a psychological thriller about art, psychology, and murder. It is rich in details about love, betrayal, evil, and the ills of psychiatric hospitals. You will be both happy and sad as you listen. I think the book is probably almost as good as the audiobook, although I really liked the voices and emotions of the audiobook. The audio is 8 hours long, but it flies by. I rate it 9/10, leaving me room to have other books above it.

Break Shot, James Taylor. 2019, is only available as an audible book, is an autobiography of his first 21 years of this folk/rock singer’s life, which features stories about his struggle with addictions and depression, six months in McLean psychiatric hospital, the origins and meanings of favorite songs, and how the Beatles and Apple records befriended him to give him the Break Shot of his life, giving him a wonderful opportunity after a childhood of challenges. At only 1:30, it is a quick listen. It is a wonderful audiobook with his singing and his own voice. I rate it 8/10.

Caffeine: How coffee and tea created the modern world. Michael Pollan. 2019. This fascinating overview of the history and uses of coffee and tea is light listening. I learned a lot from it, including that England was once more addicted to coffee than tea, and made the switch to tea because it was less expensive. More importantly, it highlights the role of caffeine in furthering the industrial revolution! Only on audiobook, and only 2 hours long. 7.5/10.

My reading recommendations from last summer were located here.

I also list my favorite reads on my favorites page here.

 

 

NY Times column: Men Call Their Own Research ‘Excellent’

This NY Times column 12/18/2019 summarizes a British Medical Journal article about bias in medical abstracts, but the same could be done for economics journals, I am sure. Worth the five minutes to read. Bottom line: Women should brag more, and editors and reviewers should get men to tone it down.

Men Call Their Own Research ‘Excellent’

Women do so much less often. And it’s not because their work isn’t as good.

Guidance for a Constructive Culture of Exchange, plus two addenda

This blog contains the excellent advice of Nancy Rose to MIT faculty and students, along with my own two addenda on Etiquette and Advice to Presenters. Here is a pdf version if you wish to print and post or forward it.

Subject:           Some guidance for our upcoming seminars

Date:   Tue, 22 Jan 2019 10:11:02 -0500

From: Nancy Rose <nrose@mit.edu>

To:       All faculty, visitors and graduate students

 

Dear Faculty and Student Colleagues,

Many of us have been thinking about how we can respond, individually and as a department, to concerns about the climate of the economics profession, and how best to affirm our mutual commitment to a supportive environment that empowers each of us to realize our full potential and contribute the best of our talents.

As one step in that ongoing effort, I am writing to share with you some guidance in advance of our department’s job market talks, which begin tomorrow.  These are not meant as rules written in stone.  But I hope they will prompt each of us to reflect on how we can ensure – in seminars and in our departmental interactions more generally – that MIT Economics combines intellectual vitality with an inclusive and respectful environment in which to exchange ideas and advance knowledge.

I hope that each of you will join me in making sure that our department’s seminar culture not only achieves our shared goals for job market seminars, but also serves as a role model for others.  I welcome feedback at the conclusion of our hiring season, as we continue our efforts to sustain a welcoming environment for all.

Thank you for your engagement on this important issue–

Nancy
Guidance for a Constructive Culture of Exchange in MIT Economics Seminars

Research seminars are one of the highlights of our department’s academic life.  They provide opportunities for participants to learn about and probe the boundaries of new research, for presenters to gain the benefit of constructive feedback, and for students to develop skills as participants in research discussions.  All of these are best achieved when the seminar environment is respectful and inclusive, and when all participants keep these goals in mind.

Building on recent discussions at the AEA meetings and elsewhere on the culture of seminars in our profession, and informed by a number of conversations with our faculty and students, this memo shares some guidance for “best practices” to help ensure that department seminars promote an open and vibrant exchange of ideas within a positive environment for both presenters and participants.

1)    Allow presenters time at the beginning to frame their talk without interruption.  A “10 minute rule” has been successfully implemented in several field seminars, allowing only brief clarifying questions during this initial period. And as that leaves 70 more minutes, please don’t feel you must get all your questions in at minute 11!

2)    Share the floor. Please remember seminar time is a scarce resource.  If you haven’t had a chance to read the paper, please try to determine whether the paper addresses your question before you ask it.  If you have already asked several questions, you might consider allowing a bit of time and space to see if others wish to contribute.

3)    Raise your hand to indicate that you wish to ask a question or contribute to the discussion.  This gives the presenter agency to mediate the discussion by calling on audience members, and avoids interrupting the presenter mid-thought, a courtesy that may be especially appreciated in job talks.  If the presenter doesn’t see someone’s hand, the organizer can help by pointing that out.  A question or comment often leads naturally to some back and forth exchange with the speaker.  But if you continue to be dissatisfied with a response, please don’t hold the talk hostage.  Instead, allow the presenter to move on, and follow up offline.  Please make every effort not to interrupt or talk over the presenter or another participant.

4)    Avoid sidebar conversations with other participants.  Keep whispers to no more than a short (clarifying) question or response.  Anything more should be deferred or asked publicly; please raise your hand and share your question or concern for the benefit of all.   Even quiet sidebar conversations between participants rarely are as unobtrusive as intended, and distract the speaker and others in the audience.

5)    Strive for fair and equal treatment.  Many studies suggest that women are likely to be interrupted more often than are men in settings like this.  The same may be true for softer-spoken participants regardless of gender.  Resist contributing to that disparity!

6)    Organizers: Please be prepared to intervene in real time if necessary to call attention to someone whose raised hand has been overlooked, to return the floor to the presenter, or to remind participants of our norms of courtesy and respect.

Thank you!

Addendum to Nancy Rose’s excellent email. Randy Ellis, March, 2019

 

Common Courtesies

7) Show up on time for the seminar.

8) Stay until the end of the seminar. If you must leave early, it is much more polite if you arrive early and privately tell the speaker that you have another commitment and will have to leave promptly at time X:XX.

9) Mute your cell phone. (If you are presenting, you could intentionally do this just before your talk, even if it was already mute, to signal to others that they should remember to do that as well.)

10) No answering phone calls in the seminar room. If you do answer a cell phone call (from vibrate mode!!!) never talk until you have left the seminar room. Mute or hang up and call back later, or make the caller wait ten seconds while you leave the room.

11) No email or web surfing in the front three rows. If you plan to be looking at your cellphone or laptop or read papers during a talk: a) try not to, or b) sit in the back of the room.

->I was at a seminar in Spain given by a woman, and every man in the room was checking their cellphone or laptop for messages, while only one of the ten women were. This was not a coincidence.

12) No napping. If you are prone to napping or had a bad night’s sleep, sit in the back of the room or don’t come.

13) Keep questions brief. Many professors think they are making brilliant comments, which others feel are bad or unnecessarily long. Err on the side of too few, and ask questions instead of giving advice.)

14) Write down your thoughts.  If you have a lot of comments or uncertainties about a presentation, write them down. Discuss or give them to the presenter at the end of the talk. Most presenters are delighted to get constructive comments after their talk.

->I have always been immensely grateful to Daniel McFadden, who instead of interrupting my job market paper presentation, gave me a page of very high-quality comments.

15) No questions during the final three minutes. Let the presenter summarize and conclude the presentation.

Advice to presenters facing inappropriate, intrusive or awkward questions, by Randy Ellis November 2019

  1. Don’t recognize any hands up or intrusions when still on your introductory few slides or five minutes. Nod them away or if rude, say “Please let me finish my overview first.” Then finish your overview while trying to anticipate questions.
  2. Never interrupt your talk in the middle of a sentence to react to a person raising their hand. Finish your sentence.
  3. Nod at someone who has their hand up to recognize them and then return later (hopefully soon) to let them ask their question.
  4. Try to give succinct answers, saving your own time.
  5. It is OK to say “I don’t know” for a factual question. Just not too often. Avoid speculation.
  6. If lots of hands go up, try to choose someone who has not already spoken. Also, take it as a signal that you have just said something confusing and try to clarify it.
  7. Learn to distinguish a comment (or suggestion) from a question.
  8. Try to have the confidence to move on with a comment rather than a question. Just say “Interesting comment” or “Thank you.” Others who agree that the comment is a tangent or of secondary importance, or rude, will respect, not disrespect, you for this.
  9. Take the comments and questions of junior faculty and people in your field more seriously than those of old farts.
  10. Restate a question if it is unclear and answer your version. Also, restate it if it was said too quietly.
  11. Be willing to repeat something you have already said, in a slightly different way, to try to improve comprehension.
  12. Try to use specific examples to motivate concepts: Pizza rather than good Q, Bart instead of Agent J.
  13. Pick on someone in the audience if it will add humor and concreteness.
  14. Feel free to say “That is a good question. I will get to that in a few more slides. Ask again if I don’t.”
  15. If the question is tangential to the point you are making in your paper, consider saying “That is an interesting point, perhaps we can discuss it after the seminar.”
  16. Writing down new ideas is a good idea, but not if the point is something obvious you should have already thought of, which makes you look foolish. Even if you already know about the idea, acknowledging the idea, such as by writing down a single word, may be good.
  17. Ask a coauthor, colleague, or friend in the audience to take notes. Tracking your time on the intro/data/ methods/results/extensions/conclusions is also helpful.
  18. Don’t say too often: “That is a really good question.” If so, you should have answered it already.
  19. If someone else is giving a very long speech, and you think others will recognize that it is inappropriate or too long, be willing to interrupt or cut it short. “I think I get what you are saying…”
  20. Don’t allow faculty sitting in the front row to ask you private questions that everyone can’t hear or understand. Interrupt them and say “Could you please speak up so that others can hear you.”
  21. If you feel that the questions have interrupted you too much to finish your talk, say “I see my time is running short. I need the next few minutes to cover XXX (my methods or results or conclusions or whatever) without interruption and get back on track.” You can do this before the final five minutes.
  22. Try not to be snarky, dismissive or rude. Strive to be gracious and open to suggestions.
  23. Assume you will have intrusions and plan a shorter talk with extra bonus slides if you have time.
  24. Assume you won’t have enough time to cover sensitivity analysis and extensions and plan accordingly.
  25. Always take your final three minutes without interruptions. Tell the audience you need to do that to finish your talk. Have a strong conclusion to use, even if you didn’t finish your results.
  26. Be sure your name is on the final slide. Don’t just show “Thank You,” but rather show your name. affiliation and paper title, as on your first slide. If you end on your conclusions, include your name. It is the single most important thing you want people to remember.
  27. Pay attention to other strong presenters (men and women) and try to imitate them.

Recognizing Mentoring

A colleague W.

Flattering, and very satisfying. Perhaps it will inspire more people to become great mentors.

Great Mentors: Randy Ellis

The full newsletter is here.

Joining ASHEcon is also a good idea. Only $40 a year for students. $95 for everyone else, and it includes a free AJHE subscription!

I hope to see you at the next ASHEcon conference in St. Louis, June 7-10.

Time to try something really different

Although I subscribe to and watch essentially every posting in The Incidental Economist, this one on value-based payment for Medicare is worth reposting and viewing. It is only 4:48  long.

Video: The Many Attempts to Improve the Value of Medicare

Upshot article by BU colleague Austin Frakt last month in the New York Times contains the cites and links for the above:

Value’ of Care Was a Big Goal. How Did It Work Out?

This video, which finds a lack of meaningful cost savings  or quality improvement, is consistent with my general view of health insurance innovations in the US:

Every 5-7 years the US health insurance industry has to come out with a new approach to address out-of-control costs and preempt true reform. These have included:

  • HMO – narrow networks
  • HMO – IPAs (Independent Physician Associations) HMOs with no teeth
  • PPOs (weaker than HMOs, but more palatable to consumers)
  • POS (Point of service) plans (combining the above two
  • CDHC – Consumer-driven health care (more choice with higher cost-sharing)
  • HDHP – High deductible plans with health savings accounts
  • Pay for performance
  • Accountable Care Organizations
  • Tiered cost-sharing
  • Value-based purchasing.

With the exception of narrow network HMOs like Kaiser (A supply-side innovation), none of these have ultimately proven to save more than 1-2 percent of costs or slow down cost growth.

The main reason for this is that all of them rely upon competition, demand-side incentives, and consumer choice driving down costs. But we have very weak competition and very poor consumer information. Plus consumers rarely change choices even when information is available.  It is true that shifting a huge financial burdens onto consumers, like high deductible strategies, can save 3-5 percent on total costs, but most people (including the wealthy) would be willing to pay this amount to avoid this level of time and financial burden. The true attraction of these approaches is as a selection tool to attract healthy people into your plan.

 

Note that CDHC and HDHP which rely on tax-exempt savings accounts are only attractive to wealthier people for whom the tax deductibility has value. Low-income people don’t benefit from these tax-favored plans, it only adds complexity to their already difficult lives.

 

All of the above strategies also increase costs by raising administrative complexity and costs for consumers, employers, health plans and providers of all types.

 

Why are new ideas adopted every five to seven years? Because that is how long it takes to try out new reforms and determine that they are not working.

 

True cost containment will take leadership and a willingness to use supply-side reforms and regulation, which is what Europe and almost other high countries use to control costs.

 

There are many challenges of dramatic restructuring and regulation such as is implied by “Medicare for All” but it is going to take something dramatic to lower cost growth to be meaningfully less than the rate of general inflation. To continue current trends will only worsen health and income inequities, worsen public burdens of government-sponsored care, and hurt US competitiveness with the rest of the world. It is easier to be critical rather than constructive, but it is time to discuss more fundamental reforms.

Congratulations on BU’s 66 presentations/coauthorships/chairs/discussants at 2020 ASSA in San Diego

Dear colleagues, students, alumni, and friends.

The preliminary program is out for the Allied Social Sciences Association (ASSA) meeting to be held in San Diego California this January 3-6, 2020, commonly known as the AEA meetings (American Economics Association). As I have done each recent year, I tabulated all of the current BU faculty, graduate students and alumni (that I recognize) who appear in the program using their name and affiliations. This count includes authors and coautors, chairs and discussants. I apologize for inevitably missing some people, particularly alumni. Let me know and I will correct on the on line versions that appear on my web blog.

This year, despite being held in just about the most remote location possible in the continental US, BU people appear 66 times, down from last year with 87 in Atlanta. This comprises 50 appearances on the program as an author or coauthor, 6 as chairs, and 10 as discussants. The winner this year with the most appearances on the program is perennial activist Pascual Restrepo with 4 appearances, followed by a three way tie between Adam Guren, Shulamit Kahn (Questrom), and Steven Terry. There were sixteen alumni I identified who presented, which is almost certainly an undercount.

This year there are 48 distinct names appearing on the program, comprising 28 faculty, 16  alumni, and four Ph.D. candidates. Of the faculty there are 16 from CAS Economics faculty (down from 21 last year), ten from Questrom School of Business, 1 from Law, and  1 from Pardee School of Global Studies.  The growth of the Questrom faculty to ten names continues its impressive recent trend, up from 8 QSB faulty last year.

End of summer reading list

Happy end of summer!

Even though the summer is winding down, it is not too late to sneak in a book or two or even keep reading them in coming weeks! Below are a few of the ones I have most enjoyed reading this summer. I recommend them all to you.

I have been relatively inactive on blogging and sending out emails this year so far, but I will have a lot more to share this fall with exciting new research and events in progress. Wishing you all well.

Maybe You Should Talk to Someone. Lori Gottlieb. 2019. I loved this book! It is written by a woman who started out as a script writer for Grey’s Anatomy, who started shadowing an MD in the emergency room to better write script, who went to medical school but then dropped out when she realized she really liked the personal interaction which is rare in our health care system, who then became a psychological therapist! The book blends her own therapy with discussions of many of her clients. I liked the insights about therapy and what it is trying to achieve. It will capture you and is a good one to recommend to and discuss at a book group.

Educated. Tara Westover. 2018. This memoire written by a lifelong Mormon growing up in Idaho under unimaginable living conditions who overcomes it to become a PhD success was voted the Amazon Editors’ #1 Pick for the Best Book of 2018. I need not say anything more.

Becoming. Michelle Obama. 2018. I am probably the last person among my book reading friends to finally read this book. Fascinating. I really like Michelle and think she is not yet done having a big impact on the US.

Interesting article and book

I just saw the abstract below to a review article by someone I know and regard highly (Rachel Kranton) in the March 2019 Journal of Economic Literature.

I took a look at the full article(14 pages) and then bought the book on line. Then I finished reading the article (15 minutes with pondering).

The Moral Economy: Why Good Incentives Are No Substitute for Good Citizens

 

(6) The Devil Is in the Details: Implications of Samuel Bowles’s The Moral Economy for Economics and Policy Research
Rachel Kranton
All economists should buy and read The Moral Economy by Samuel Bowles. The book challenges basic premises of economic theory and questions policies based on monetary incentives. Incentives not only crowd out intrinsic motivations, they erode the ethical and moral codes necessary for the workings of markets. Bowles boldly suggests that successful policies must combine incentives and moral messages, exploiting complementarities between the two. This essay argues that to achieve this objective, economists must study the local institutions and social context and engage untraditional data to uncover the interplay of incentives and identity.

The JEL article is free at the Full Text access link, or here.

 

The book came out in 2017, but I had not read a review. I am looking forward to reading the book.

Congratulations on BU’s 87 presentations/coauthorships/chairs/discussants at 2019 ASSA meetings

As I have done in previous years, I tabulated the names I could find from BU faculty, students, and alumni on the preliminary ASSA (Allied Social Science Associations) program for the Atlanta AEA (American Economics Association) meetings, the largest annual US gathering of economists.

BU set a new record for its presence at the 2019 ASSA/AEA (American Economics Association) meetings with BU faculty, students or alumni names appearing 87 times. This is up 22% from the 71 times in 2017 in Philadelphia, and surpases the count for the 2015 ASSA meetings, which were held in Boston, (83 appearances, with a home field advantage).

Of those 87 appearances there are

60 presenters or coauthors (up from 43 last year!) (ASSA does not differentiate coauthors from presenters in the ASSA program.)

21 discussants

6 session chairs.

Of those 87 appearances:

27 are by CAS Economics Department faculty (21 distinct economics faculty names are on the program– one more than last year!)

18 are by Questrom School of Business faculty (8 distinct names)

1 is from the BU SPH faculty

1 is by a PhD student who submitted a paper while still a student

1 is by a former MA student (poster presentation) who submitted while still a student

40 are by BU Ph.D. Alumni (Up from 22 last year!) These are clearly undercounted since it is hard to recognize all of their names.)

The busiest BU participant at the ASSA this year will be alumnus Kristopher Gerardi, Federal Reserve Bank of Atlanta with four roles.

Many people will be very busy at ASSA this year with three roles each Pascual Restrepo (BU Econ), Andrea Vedolin(Questrom), Evgeny Lyandres (Questrom), Keith Marzilli Ericson (Questrom),Robert Metcalfe (Questrom), Francisco Pino (U. Chile) and Jonathan Hersh (Chapman U.)

Recall that these numbers count chairs, discussants and coauthors equally. Questrom factulty were particularly active this year at getting on the ASSA program.

I apologize for any names that I have inadvertently missed, but creating this list requires looking through about 10,000 names of authors, chairs and discussants for familiar names. If you send corrections to me, I will at least correct them on my blog posting of this email, which is linked here.

The BU reception will be Saturday, January 5, 2019 from 6 to 8pm at the Atlanta Marriott Marquis, room International C..All are welcome, even if you are not registered for the conference.

A detailed list of papers and names that may help with planning your travel, learning what your colleagues are up to or making corrections are below. They are sorted chronologically by time.

It is not too early to begin planning which papers you want to present at the ASSA 2020 (January 3-5, 2020 (Friday, Saturday, & Sunday)
San Diego).

Also note that the AEA registration and housing reservations will open on September 12th at 11 a.m. EDT. Link is here.

Congratulations to BU’s Class of 2018 Economics graduates!

I have been on sabbatical, and hence am late to do this calculation and blog. Alas my sabbatical has come to an end.

Please celebrate the BU students who earned 590 degrees in Economics at Commencement this May!

This year the program honors:

18 Ph.D. recipients

231 Master’s degree recipients (MA, MAPE, MAEP, MAGDE MA/MBA, BA/MA)

341 BA recipients (including BA/MA)

This total of 590 degrees is up from 556 (6%) since 2017, following a 12% increase in 2017.

These numbers may undercount the total for the year since they may exclude some students who graduated in January.

In 2018 there were 18 PhDs, 231 Master’s degree recipients, and 341 BA recipients

In 2017 there were 14 PhDs, 215 Master’s degree recipients, and 327 BA recipients

In 2016 there were 22 PhDs, 203 Master’s degree recipients, and 273 BA recipients

In 2015 there were 22 PhDs, 155 Master’s degree recipients, and 305 BA recipients.

In 2014 there were 17 PhDs, 207 Master’s degree recipients, and 256 BA recipients.

Altogether 19 Ph.D. students agreed to be shown as obtaining jobs on our placements web site this year (versus 13 in 2017 and 23 in 2016). Not all graduates choose to be listed.

To see the Ph.D. placements visit the web site linked here.

http://www.bu.edu/econ/gradprgms/phd/placements/

The department’s  website now lists 38 regular faculty (down one from last year) with titles of assistant, associate or full professors, a number which is 3 below the number of professors in 2014 (our peak year) as listed on the commencement programs. Here are the recent counts of faculty.

2018: 38 tenured or tenure-track faculty, of which 4 are women (10%); 12 non-TT faculty, of which 3 are women (25%); 50 total faculty, of which 7 are women (14%). Of the TT faculty, there are 11 assistant (2 women), 7 associates (1 woman), and 23 full professors (1 woman)

2017: 39 tenured or tenure-track faculty, of which 3 are women (8%); 12 non-TT faculty, of which 3 are women (25%); 51 total faculty, of which 6 are women (12%)

2016: 38 tenured or tenure-track faculty, of which 5 are women (8%);  7 non-TT faculty, of which 1 are women (14%); 47 total faculty, of which 6 are women (12%)

2015: 40 tenured or tenure-track faculty, of which 5 are women (12%); 7 non-TT faculty, of which 2 are women (29%); 47 total faculty, of which 7 are women (15%)

2014: 41 tenured or tenure-track faculty, of which 6 are women (15%); 4 non-TT faculty, of which 1 is a woman (25%); 45 total faculty, of which 7 are women (16%)

Am I finally Famous? Interview in La VANGUARDIA March 10 2018

I was interviewed and photographed for Barcelona’s major newspaper, LA VANGUARDIA, and the results appeared on Saturday, March 10 on the La Contra page, which is the most widely read part of that paper since it is on the last page and tries to be controversial. Because it is published in Catalan (a language spoken in Spain), it only paraphrases what I said. It seems to reflect what I said very well, which was mostly about healthcare in the US and Spain and Obamacare. The only error is in saying I earned my PhD from Harvard instead of MIT.

I have had more complements about this article than any of my others (in US, Australian, Colombian, Icelandic, French, German, and Danish). Perhaps because the Catalans really like their newspapers!

I especially like the picture!

Medicaid recipients are already working, fraud in SNAP is 1%, and Medicare would be cut

It is nice while on sabbatical to avoid the fray of politics, but our president’s recent attack on Medicaid, SNAP (food stamps) and Medicare makes me want to share the following three sets of links.

The bottom line of the Medicaid video (4:52) summary of two studies is that “able bodied” eligibles represent only about 3% of Medicaid recipients – about the same as the unemployment rate.

The bottom line of the September 5, 2017 press release from the US Department of Agriculture study of fraud in the SNAP program is that fraud remains at about one percent of payments, where it has been since 2006-2008. Less than most public OR private activities.

The bottom line on Trump’s own budget report is that he is lying and yes they are asking for major cuts to Medicare.

Here are the links.

Medicaid

Healthcare Triage News: But, But, Medicaid Recipients Are Already Working

Posted: 15 Feb 2018 05:24 AM PST

Recently, the Trump administration put forward plans to force all the able-bodied lazy people with Medicaid coverage to finally get jobs. The problem with this is that pretty much all the Medicaid recipients who can work already have jobs. So, how’s all this going to work?

@aaronecarroll

SNAP program fraud.

 

This is from a Press Release dated September 5, 2017 on the US Department of Agriculture web site.

 

The DOA examines and reports on fraud regularly. The latest report summarizes it as  “approximately one cent on the dollar”. This is very low compared to most public or private activities.

Here is a longer quote.
“The report indicates that the vast majority of trafficking – the illegal sale of SNAP benefits for cash or other ineligible items – occurs in smaller-sized retailers that typically stock fewer healthy foods. Over the last five fiscal years, the number of retailers authorized to participate in SNAP has grown by over 40 percent; small- and medium-sized retailers account for the vast majority of that growth. The rate of trafficking in larger grocery stores and supermarkets—where 82 percent of all benefits were redeemed—remained low at less than 0.5 percent.

While the overall trafficking rate has remained relatively steady at approximately one cent on the dollar, the report attributes the change in the rate to 1.3 percent primarily to the growth in small- and medium-sized retailers authorized to accept SNAP that may not provide sufficient healthful offerings to recipients.

 

Medicare

I looked over the Trump administration’ budget proposal. My own view is that some of it is reasonable, but much of it reflects the usual politically infeasible projects that will never be approved by Congress but will distract voters and news coverage from the more substantive problems with the budget, such as the increased defense spending, the Wall, the lack of infrastructural investment, and the ridiculous tax cuts. It will be viewed as a victory when congress agrees NOT to cut Medicare.  But it will be a hollow victory. There is no way around the fact that it cuts certain Medicare benefits as many others have noted  – take your pick (Reuters, Bloomberg, CNBC, ThinkProgress) and violates his promises in 2016. Or if you prefer fantasy you can just listen to Fox News that reports “Trump would again spare Social Security retirement benefits and Medicare as he promised during the 2016 campaign.”

 

Impact of the GOP tax reform on tax-favored donations

This extended blog will mostly be of interest to Americans thinking about end of year tax strategies. It extends a discussion among some Yale colleagues about the current tax bill as well as some calculations based on web sources. This blog focuses on the new high standard deduction and the Alternative Minimum Tax (AMT) provisions, and what it means for charitable donations. Much of it is oriented toward income earners earning $150k-500k. There are of course many, many other features of the new tax bill not examined.

My glimpse at the new tax tables, included below, are that most people in the range from $150-500k will see tax cuts of their marginal rate of about 2-6%, unless they are affected by the AMT. Those affected by the AMT will see significant lump sum gains but marginal rates that are similar to this years, at 26 or 28 percent.

This discussion will be complex for many unless you are used to thinking about the tax subsidies for donations and the implications for timing of donation. (Most people donate because it just feels good.)

My bottom line is at the bottom of this email. COMMENTS/CORRECTIONS WELCOME.

I am not a tax expert and you should get expert advice before acting on anything you read here.

The standard deduction is proposed to be raised to $24,000 for a married couple filing jointly. More important are the AMT changes for high income people.

So under the new system a married couple can claim itemized deductions (look at Sch A of your return for last year for this amount) of a minimum of $24,000, ($12k if single) even if they have no itemized deductions.

The main itemized deductions for most people are mortgage interest, state and local income and property taxes, and charitable contributions.

Base case: Assume you don’t have any mortgage interest and your 2017 itemized deductions are say $40,000 in state income and property taxes, and $5,000 in charitable contributions:

Under current law you claim itemized deductions of $45,000 which is more than the standard deduction.

Under proposed 2018 law the allowable itemized deductions will be $10,000 state income and property taxes plus $5,000 for the donations. So if a person claims the standard deduction of $24,000 – he gets this regardless of whether he makes a charitable contribution of nil or $14,000.  So the first 14k of charitable deductions doesn’t produce a tax benefit.

Wrinkle 1:

 

If you have deductible mortgage interest next year (Say $10,000) from an existing first mortgage next year, then the interest on it can be added to your $10,000 of local property taxes and the threshold for donations affecting your taxes would be only $4000. Since 10k+10k+4k=$24,000.

Wrinkle 1a: home equity line of credit mortgage interest is no longer deductible at all.

Wrinkle 1b: for any new mortgages taken out after Dec 15, 2017, only the interest on the first $750k of home mortgage will be deductible.

 

Important Wrinkle 2:

If your income is subject to the alternative  minimum  tax (AMT) for 2017 then the marginal value of a deduction this year is either 26 or 28 percent, depending on where you are in the phase out of the AMT, since these are the AMT income marginal rates. Your AMT is calculated from your income without taking most deductions but after a moderately large exemption. The AMT is based on your Alternative Minimum Taxable Income AMTI (See intuitive discussion  below).  Call this Y. Taxes are applied to Y minus the AMT standard exemption, call it Z, which is $84,500 for joint filers and $54,300 for others. The exemption starts to phase out once your income exceeds Q=$160,900 for joint filers, and $120,700 for singles. Under the proposed new tax bill, the AMT exemption (Z) is increased and the point at which the exemptions begin to be phased out are increased, but the tax rates remain the same. Z is decreased by $.25 for each dollar  of AMTI above the phase out threshold Q.

 

The following focuses on joint filers and are based on a recent article by the Tax foundation (Link below).

 

Currently, if Y your AMT income is $160,900 then the AMT tax is

AMT=.26*(Y-Z) = .26*(160,900-84,500)=$19,864

 

If your AMT income is 250k then your AMT tax would be

 

Y=250,000

Q=160,900

Z = 84,500-.25(250,000-160,900)  (reflecting the phase out of the exemption starting at 160,900)

AMT=0.28*(Y-Z) = .28*(250000-62225) = $52,577

 

If your income is 500,000 at which the exemption Z is currently fully phased out, then your AMT would be

AMT = .28*(500000 – 0) = $140k.

 

(The .26 rate applies when your Y = AMTI is less than $187,800, while the “higher rate”  of 28% applies to more than that. This step also creates modest infra-marginal changes that I have ignored. Silly complexity…)

 

The current law raises the exemption amounts, and also raises the threshold at which the exemption starts to be  phased out.

 

“Exemption amounts under the conference agreement are increased from their current level of $84,500 for joint filers and $54,300 for other filers to $109,400 and $70,300, respectively.”

 

More importantly, the AMT exemption does not begin to phase out until alternative minimum taxable income exceeds $1 million for joint filing households. So for the three households just examined the new AMT amounts would be:

 

AMT only kicks in at AMTI >= 160,900.

 

At Y = 160,900: AMT=.26*(Y-Z) = .26*(160,900-109,400)=$13,390 a reduction of $6,474 from the existing AMT tax.

At Y = $250,000 AMT = .28*(Y-Z) = .28*(250,000-109,400)=$36,556 a reduction of $16,021

At Y=$500,000: AMT = .28*(Y-Z) = 0.28*(500,000-109,400) = $109,400 a reduction of $30,632

You can interpolate pretty well between these amounts using the following figure. The slight nonlinearity results from the change from 26% to 28% at Y=187,800.tax reform fig 1 2017

 

These AMT amounts are only relevant when they are more than the taxable income calculated using the normal way (using deductions and the standard exemptions). For many, these AMT changes are the gifts of the current tax reform.

 

So the AMT, which currently affects about half of all HH  with incomes above $200k is projected to affect a smaller number of people after the reform mostly because of the higher exemption.

 

This AMT change is a big cost component of the current reform, but gets less attention since it is harder to explain.

 

“All told, the Joint Committee on Taxation estimated that these [AMT] changes would reduce federal revenues by $637.1 billion over the next decade, compared to current law.” This is 42% of the total deficit increase!

 

https://taxfoundation.org/conference-report-alternative-minimum-tax/

 

Here is a brief, non-technical discussion of the Alternative Minimum Taxable Income AMTI.

Some of these items added back into your income include personal exemptions, state and local income taxes, miscellaneous itemized deductions and mortgage interest on home equity debt. Accordingly, you’re more likely affected by AMT if you have a high number of exemptions (a larger family), high state income and property taxes and/or high miscellaneous itemized deductions like significant investment management fees.

You may also have to include certain types of income that you wouldn’t normally count in your regular taxable income, such as exercising incentive stock options or tax-exempt interest from private activity bonds. The disallowance of deductions and addition of income leads to your Alternative Minimum Taxable Income (AMTI).

For 2017, you pay a tax rate of 26% on AMTI of $187,800 or less for those filing single, married filing jointly, head of household or qualify widower. For married filing separate taxpayers, the income threshold stops at $93,900.  The tax rate grows to 28% of income over those amounts. Multiplying your AMTI minus your exemption times the corresponding tax rate gives you your tentative minimum tax.

You may have some additional tax due if you reported capital gains distributions, qualified dividends, and/or used the foreign tax credit, but your software should add those for you.

You should note that AMT is only the difference between your regular income tax and the tentative minimum tax amount calculated through AMT. For example, if you owed $30,000 in regular income tax and your tentative minimum tax amount was $33,000, AMT of $3000 will show up on line 45 of your Form 1040.

Here is another discussion from CBSNews.

 

What’s the deal with the alternative minimum tax?

For corporations, the AMT disappears.

That’s not the case for individual filers, but fewer will have to pay it, at least.

  • Exemption amounts will increase from $84,000 for joint filers under the current law level to $109,400. Single filers will see that number increase from $54,300 to $70,300.
  • The exemption currently phases out for joint filers at $160,900, and $120,700 for individuals. Under the tax bill, that phaseout would kick in at $1 million for married filers and $500,000 for those who are single. Above the threshold, filers lose 25 percent of their exemption, that is, $0.25 on every dollar in income.

What if I give to charity?

The charitable deduction will remain as it is. So, if you itemize your deductions, you may be able to deduct charitable contributions that are made to qualifying organizations. According to the IRS, you may deduct up to 50 percent of your adjusted gross income, although some filers are limited to 20 percent and 30 percent.

 

https://www.cbsnews.com/news/gop-tax-bill-how-the-new-tax-plan-will-affect-you/

 

Here are the current “final” tax rates and intervals as of 10:30 am Tuesday morning.

 

https://www.cnbc.com/2017/12/15/find-your-new-tax-brackets-under-the-final-gop-tax-plan.html

See below for a breakdown of the proposed income tax brackets for singles.

Rate Taxable Income Bracket
10% 0 to $9,525
12% $9,525 to $38,700
22% $38,700 to $82,500
24% $82,500 to $157,500
32% $157,500 to $200,000
35% $200,000 to $500,000
37% $500,000 and up

Here are the proposed rates for married couples who file jointly.

Rate Taxable Income Bracket
10% 0 to $19,050
12% $19,050 to $77,400
22% $77,400 to $165,000
24% $165,000 to $315,000
32% $315,000 to $400,000
35% $400,000 to $600,000
37% $600,000 and up

For comparison, here would be the 2018 brackets under current tax law, adjusted for inflation.

Rate Taxable Income Bracket-Single Taxable Income Bracket-Married Filing Jointly
10% 0 to $9,525 0 to $19,050
15% $9,525 to $38,700 $19,050 to $77,400
25% $38,700 to $93,700 $77,400 to $156,150
28% $93,700 to $195,450 $156,150 to $237,950
33% $195,450 to $424,950 $237,950 to $424,950
35% $424,950 to $426,700 $424,950 to $480,050
39.60% $426,700 and up $480,050 and up

 

Here it is in a graph for joint filers. This assumes everyone just takes the standard deduction of $24,000.

tax reform fig 2 2017

Of course, low income people are not likely to have deduction that exceed the $24,000 standard deduction while high income people are more likely to. Most of the changes are only visible at the higher income levels…

 

Putting together the new tax schedule with the new AMT taxes, and assuming joint filers only take the $24,000 standard deduction, the following reveals the key role that the new AMT plays.

tax reform fig 3 2017

 

For people who have lots of possible deductions under the new tax system, the AMT places a much lower minimum on tax payments than the old one.

The new AMT schedule is substantially more attractive to high income salary earners affected by the AMT. The relevant tax rate for them is 28%.

Not shown in this figure is that eventually the difference between the existing and new AMT disappears at about $1.4 million.

 

My bottom line from this is:

 

In general, under the new tax program, bunching of charitable donations and concentration of deductions into a single year will be attractive, so that you  might take the standard deduction one year and not the next.

 

The AMT makes it unclear whether bunching in 2017 is particularly worthwhile relative to 2018, since the 26% or 28% rates in the AMT may be less than the new marginal rate next year when combined with a more favorable AMT in future years. In short, a large donation this year may mean that on the margin you only get a 26-28% tax subsidy, while a donation next year may have a 33-37% deduction for large donors with moderately high incomes (<$500k).

 

For salary earners not affected by the AMT, donations this year are likely to be more favored than next year, when the lower rates and higher thresholds for tax rates will matter.

 

If you want to take a deduction for a donation THIS YEAR but decide who it goes to next year, you could open a  Donor advised fund, such as at Fidelity.

 

My bottom, bottom line is that I don’t expect large tax savings from moving around deductions between this year and next if you are affected by the AMT. A good strategy is to give what feels right.

 

Of course, all of this is based on the current tax bill, which could change or not be passed…

Three great books to read

While on sabbatical this year, I have been enjoying some extra reading. I have just added two new books and one old one to my favorites list on my web site. I recommend them all highly to you.

The Undoing Project: A Friendship That Changed Our Minds Michael Lewis Dec 6, 2016 This remarkable and easy to read book is written as a biography of two Israelis, Daniel Kahneman and Amos Tversky, but along the way covers a long list of their remarkable insights and experiments. I highly recommend it to people who tried to read the original, dense book Thinking, Fast and Slow by Kahneman and Tversky, two pioneers of behavioral economics.

Decisive: How to Make Better Choices in Life and Work. Chip Heath and Dan Heath, Mar 26, 2013. This is more of a how-to book for business managers and anyone about ways of making better decisions, but along the way it has a nice overview of the many biases and irrationalities in our thought process. First example: when asked to choose between A and B, don’t. Instead figure out how to do A+B or something else even better. Lots of anecdotes and brief research summaries.

Blink: The Power of Thinking Without Thinking Malcolm Gladwell 2007. I read this book a long time ago, but added it here since it remains a very powerful and important book. I recommend and have read almost all of Malcolm Gladwell’s work (See especially Outliers and The Tipping Point). His work gives important insights into how people actually make decisions, which are often based on simple heuristics and very little information compared to how decisions are typically modeled by economists.

Holiday cheers, congrats to BU, and a psychedelic BU alumni site from 1970-1997!

Today, the first day of Hanukah and two weeks before Christmas and Kwanza, I am writing to wish my colleagues and my BUHealth blog readers a peaceful and happy holiday, whatever your faith background. I am loving my sabbatical at Boston College this fall and looking forward to our stay in Barcelona starting in mid-January. I feel fortunate to be healthy and happy in my warm home.

In case you missed it, you may be happy to hear that BU moved up even further in the Times Higher Education ranking, to become sixth in the world for “employability”.

http://www.bu.edu/today/2017/bu-ranks-sixth-internationally-in-employability-of-graduates/

The quotes and discussion by BU president Bob Brown are excellent and emphasizes BU’s recent history. But I think another strong reason BU is so well-known internationally is our long history of training top leaders from all over the globe, particularly PhD students in economics. The following link is not up-to-date nor is it BU supported, but this web page created by BU emeritus professor Oldrich Kyn in the late 1990s shows how successful BU was at creating world leaders and scholars all over the globe back then. Check it out when you have ten+ minutes to explore your favorite countries or track down a country-mate BU alum in your own home country. It is interesting to see the remarkable achievements of BU alumni in an era when South Asian, African and Latin American PhD students outnumbered the East Asian and Europeans. Even then, Americans were a modest minority in the PhD program, as they are today. You get to decide how you like Oldrich’s psychedelic colorizing of mostly old black and white images…

US health spending and global burden of disease

I want to thank Veronica Vargas for sending me the following link from the Institute for Health Metrics and Evaluation (IHME) , which features innovative ways of displaying different cuts of US and international data from a massive data files. Viewing this site will perhaps take you fifteen minutes or more to get a feel. It is staffed by the University of Washington, but appears to be funded largely by the Gates Foundation. It has been around for a while, but they are making a big push on its features this fall.

The first link decomposes spending in the US by  disease, by broad type of service (pharmacy, IP, OP, Dentist, ER).

They document the well-known result that about half of the US increase is due to price increases, not intensity or illness, although aging and pop growth contribute.US costs are higher than the rest of the world largely because our prices paid for all types of care are much higher than elsewhere. And increasingly so.

 

Here is a direct link to the interesting interactive figures. Try the four different tabs across the top if you are curious. (Is a little slow on my wireless laptop.)

https://vizhub.healthdata.org/dex/

It allows you to drill down to questions such as how much was spent on individual disease for certain ages, on emergency department.

If you click on “visualizations“ in the upper right, you get different views that can be plotted, which are very extensive.

Or start here http://www.healthdata.org/results/data-visualizations

 

Below is a link to the article originally posted, along with a sample figure.

 

Factors associated with increases in US health care spending, 1996–2013

Here is one that lets you choose one or compare two or more countries disease burdens along multiple dimensions.

Global Burden of Disease module lets you answer questions as specific as how many people die of air pollution in India in 2013.

See which causes of death and disability are having more impact and which are waning.

This is not a site oriented toward hypothesis testing, although it does include confidence intervals on many estimates (which seem to only reflect sampling precision, not other sources of uncertainty such as the quality of the underlying data.) For me, the main use will be in writing in the introduction of a paper so as to summarize how large a problem is, or how many people have a given condition, or how it is growing etc. The international breadth is stunning. At a different level, it is a good example of how big data can be manipulated using “cubes” and different cuts of the data to show fascinating patterns (girls less than 1 year cost $11,000 each on average, which drops to $1,600 age 5-9, and it is not until age 65 in the US that female mean cost is again over $11,000. It peaks at $31,000 per year over age 85.)

 

Be forewarned: you can spend a lot of time playing around…

 

 

The quintessential challenge of our time

“…the quintessential challenge of our time: the ascendance of belief over fact, outrage over thoughtful debate, and the accessibility of an endless supply of “information” that confirms our preexisting beliefs, whatever they may be. In a sociopolitical climate in which disgust often substitutes for disagreement, many people recognize the futility of using evidence to establish common ground, but few seem to know what to do about it.”

BU to be well represented at the ASSA 2018 annual meetings

Dear BU colleagues, students, alumni, and friends,

Even though I am just beginning my sabbatical, I thought I would do this tabulation from the preliminary program of the ASSA (Allied Social Science Association) annual meetings which will be in Philadelphia January 5-7, which is linked here.  .

I apologize for any names that I have inadvertently missed, but creating this list requires looking through 11,000 names of authors, chairs and discussants for familiar names, and sometimes checking their affiliations. If you send corrections to me, I will correct them on my blog which is linked here.

BU will not quite set a record for presence at the 2018 ASSA (commonly called simply the AEA American Economics Association) meetings with BU faculty, students or alumni names appearing 71 times.  The last time I counted was for the 2015 ASSA meetings, which were held in Boston, and BU had 83 appearances, but with a home field  advantage.

 

Of those 71 appearances there are

43 presenters or coauthors (ASSA does not differentiate them in the program)

18 discussants

10 session chairs.

 

Of those 71 appearances,

34 are by CAS Economics Department faculty (20 distinct names – two more than the Boston ASSA!)

14 are by Questrom School of Business faculty (6 distinct names)

22 are by current or former BU students. (20 distinct names)

 

The busiest participant this year will be our new associate professor Tarek Hassan, with four papers presented and one session chaired. This impressive activity spearheads the remarkable ten appearances from the five new BU faculty joining us in Economics this fall. Others who will be busy with three appearances each include Kevin Lang, Robert Margo, Pascual Restrepo.

Join me in congratulating our busiest scholars who are presenting (or coauthored a presentation), chairing and discussing at the ASSA in January. There will be a BU reception on Saturday evening as usual – look for announcements in the fall for the time and room.

A detailed list of papers and names that may help with planning your travel, learning what your colleagues are up to or making corrections are below. They are sorted chronologically by time.

It is not too early to begin planning which paper you want to present at the ASSA 2019 (Atlanta).
