Here is John Cochrane, Megan McArdle, Ryan Bourne and myself on the pandemic. Lots of good material. John Cochrane was excellent on testing in a pandemic and why it’s different than medical testing, starting around 22:00. My follow-up also had some good material, our antibodies, our selves.
Ryan Bourne’s book Economics in One Virus is very good.
Many people are coming around to First Doses First, i.e delaying the second dose to ~12 weeks. Atul Gawande, for example, tweeted:
As cases and hospitalizations rise again, we can’t count on behavior alone reversing this course. Therefore, it’s time for the Biden admin to delay 2nd vax doses to 12 weeks. Getting as many people as possible a vax dose is now urgent.
Now urgent??? Yes, I am a little frustrated because the trajectory on the new variants was very clear. On January 1, for example, I wrote about The New Strain and the Need for Speed (riffing off an excellent piece by Zeynep Tufekci). Still, very happy to have Gawande’s voice added to the cause. Also joining Gawande are the power trio of Govind Persad, William F. Parker and Ezekiel J. Emanuel who in an important op-ed write:
If we temporarily delay second doses …that is our best hope of quelling the fourth wave ignited by the B.1.1.7 variant. Because we did not start this strategy earlier, it is probably too late for Michigan, New York, New Jersey and the other Northeastern states. But it might be just in time for the South and California — the next places the more infectious strain will go if historical patterns repeat.
…Drug manufacturers selected the three- or four-week interval currently used between doses to rapidly prove efficacy in clinical trials. They did not choose such short intervals based on the optimal way of using the vaccines to quell a pandemic. While a three- or four-week follow-up is safe and effective, there is no evidence it optimizes either individual benefit or population protection.
…Some complain that postponing second doses is not “following the science.” But the scientific evidence goes far beyond what was shown in the original efficacy trials. Data from the United Kingdom, Israel and now the Centers for Disease Control and Prevention shows that first doses both prevent infection and reduce transmission. In people with prior infection, experts are beginning to recognize that a second dose could provide even less benefit. Following the science means updating policies to recognize new evidence rather than stubbornly maintaining the status quo.
Emanuel is on Biden’s COVID-19 task force so consider this op-ed running the flag up the flagpole. I predict Topol will fall next.
I would be surprised, however, if the US changes course now–too many people would then ask why didn’t we do this sooner?–but dose stretching is going to be important for the rest of the world. Why aren’t we doing more to investigate fractional dosing? Even if we went to half-doses on the second dose–the full second dose appears to be strong–that would still be a significant increase in total supply.
Addendum: I have argued for sending extra doses to Michigan and other hot spots such as NJ. Flood the zone! The Biden administration says no. Why? Production is now running well ahead of distribution as more than 50 million doses have been delivered but not administered. It would be a particularly good idea to send more single-shot J&J to reach hard to reach communities–one and done.
Kibbutz is bottom‐up socialism on the scale of a small community. It thereby avoids the worst problems of state socialism: a planned economy and totalitarianism. The kibbutz, as a unit, is part of a market economy, and membership is voluntary: you can leave at any time. This is “socialism with a human face” — as good as it gets.
Being a member of a kibbutz taught me two important facts about socialism. The first is that material equality does not bring happiness. The differences in our material circumstances were indeed minimal. Apartments, for example, if not identical, were very similar. Nonetheless, a member assigned to an apartment that was a little smaller or a little older than someone else’s would be highly resentful. Partly, this was because a person’s ability to discern differences grows as the differences become smaller. But largely it was because what we received was assigned rather than earned. It turns out that how you get stuff matters no less than what you get.
The second thing I learned from my experience of socialism was that incentives matter. On a kibbutz, there is no material incentive for effort and not much incentive of any kind. There are two kinds of people who have no problem with this: deadbeats and saints. When a group joined a kibbutz, the deadbeats and saints tended to stay while the others eventually left. I left.
In retrospect, I should have known right away, from my first day, that something was wrong with utopia. On my arrival, I was struck by the fact that the pantry of the communal kitchen was locked.
Read the whole thing.
Addendum: Ilya Somin has interesting comments especially on kibbutz versus the lesser known moshavim.
NYTimes: The Centers for Disease Control and Prevention and the National Institutes of Health announced a new initiative on Wednesday to help determine whether frequent, widespread use of rapid coronavirus tests slows the spread of the virus.
The program will make rapid at-home antigen tests freely available to every resident of two communities, Pitt County, N.C., and Hamilton County, Tenn., enough for a total of 160,000 people to test themselves for the coronavirus three times a week for a month.
“This effort is precisely what I and others have been calling for nearly a year — widespread, accessible rapid tests to help curb transmission,” said Michael Mina, an epidemiologist at Harvard University who has been a vocal proponent of rapid, at-home testing programs.
Imagine a parallel universe where Americans were tested massively, constantly, without care for cost, while those who tested negative continued more or less about their daily life.
In fact, that parallel universe exists. It’s the National Football League.
..After an October outbreak, the NFL moved to daily testing of all its players and instituted new restrictions on player behavior and stricter rules on ventilation and social distancing. The league also used electronic tracking bracelets to trace close contacts of people who tested positive. Throughout the season, the NFL spent about $100 million on more than 900,000 tests performed on more than 11,000 players and staff members. In January, the CDC published an analysis of the league that concluded, “Daily testing allowed early, albeit not immediate, identification of infection,” enabling the league to play the game safely.
You could write off the NFL’s season as the idiosyncratic achievement of a greedy sport with nearly unlimited resources. But I can think of another self-interested institution with nearly unlimited resources: It’s the government of a country with a $20 trillion economy and full control over its own currency. Unlike the NFL, though, the U.S. never made mass testing its institutional priority.
“The NFL was almost like a Korea within the United States,” Alex Tabarrok told me. “And it’s not just the NFL. Many universities have done a fabulous job, like Cornell. They have followed the Korea example, which is repeated testing of students combined with quick isolation in campus dorms. Mass testing is a policy that works in practice, and it works in theory. It’s crazy to me that we didn’t try it.” Tabarrok said we can’t be sure that a Korean or NFL-style approach to national testing would have guaranteed Korean or NFL-style outcomes. After all, that would have meant averting about 500,000 deaths. Rather, he said, comprehensive early testing was our best shot at reducing deaths and getting back to normal faster.
Superb NYTimes disquisition on a masterpiece of Indian miniature painting. The text, formatting, visuals, all beautifully done–better than any museum exhibit I can recall.
In addition to the subject matter this piece has a lot to say about online education and how news is becoming a winner take-most market. Note what Tyler and I said on endogenous fixed costs in our piece on online education in the AER and consider how many newspapers could put together a display of this quality.
Shaked and Sutton (1987) and Sutton (1998) show that when quality is primarily vertical, meaning that there is a measure of quality such that all consumers agree that higher quality is more preferred, then increased market size does not result in reduced concentration. Instead, as market size increases, firms invest more in quality, which endogenously increases economies of scale and maintains market concentration.
Along related lines, Berry and Waldfogel (2010) show that there are many more restaurants in larger than smaller cities, but even as city size increases by a factor of 10 there is no tendency for the number of newspapers to increase. Larger cities have more restaurants than smaller cities because economies of scale are limited and quality differs “horizontally,” according to taste (thus, larger cities have more diverse restaurants). Yet larger cities are served by roughly the same number of newspapers as smaller cities because quality is more vertical, most newspaper consumers want more coverage, better writers and more features.
New paper from Jeffrey E. Harris:
The decades-long effort to produce a workable HIV vaccine has hardly been a waste of public and private resources. To the contrary, the scientific know-how acquired along the way has served as the critical foundation for the development of vaccines against the novel, pandemic SARS-CoV-2 virus. We retell the real-world story of HIV vaccine research – with all its false leads and missteps – in a way that sheds light on the current state of the art of antiviral vaccines. We find that HIV-related R&D had more than a general spillover effect. In fact, the repeated failures of HIV vaccine trials have served as a critical stimulus to the development of successful vaccine technologies today. We rebut the counterargument that HIV vaccine development has been no more than a blind alley, and that recently developed vaccines against COVID-19 are really descendants of successful vaccines against Ebola, MERS, SARS-CoV-1 and human papillomavirus. These successful vaccines likewise owe much to the vicissitudes of HIV vaccine development.
Here’s a great video on FastGrants, the fast funding-institution started by Tyler and Patrick Collison to fund COVID research at a speed that could make a difference on the ground. And it did.
Lots of other people stepped in with funding including Arnold Ventures, The Audacious Project, The Chan Zuckerberg Initiative, John Collison, Crankstart, Jack Dorsey, Kim and Scott Farquhar, Paul Graham, Reid Hoffman, Fiona McKean and Tobias Lütke, Yuri and Julia Milner, Elon Musk, Chris and Crystal Sacca, Schmidt Futures, and others.
The list of funded people and projects is long and impressive and while the grants were fast, the payoff is going to last well beyond the pandemic.
Thanks, Tyler and Patrick!
I will be speaking with Jennifer Doleac and the Manhattan Institute’s Charles Lehman about Misdemeanor Prosecution on Clubhouse 8pm EST tonight (Wed. March 31).
Misdemeanor Prosecution (NBER) (ungated) is a new, blockbuster paper by Agan, Doleac and Harvey (ADH). Misdemeanor crimes are lesser crimes than felonies and typically carry a potential jail term of less than one year. Examples of misdemeanors include petty theft/shoplifting, prostitution, public intoxication, simple assault, disorderly conduct, trespass, vandalism, reckless driving, indecent exposure, and various drug crimes such as possession. Eighty percent of all criminal justice cases, some 13 million cases a year, are misdemeanors. ADH look at what happens to subsequent criminal behavior when misdemeanor cases are prosecuted versus non-prosecuted. Of course, the prosecuted differ from the non-prosecuted so we need to find situations where for random reasons comparable people are prosecuted and non-prosecuted. Not surprisingly some Assistant District Attorneys (ADAs) are more lenient than others when it comes to prosecuting misdemeanors. ADH use the random assignment of ADAs to a case to tease out the impact of prosecution–essentially finding two similar individuals one of whom got lucky and was assigned a lenient ADA and the other of whom got unlucky and was assigned a less lenient ADA.
We leverage the as-if random assignment of nonviolent misdemeanor cases to Assistant District Attorneys (ADAs) who decide whether a case should move forward with prosecution in the Suffolk County District Attorney’s Office in Massachusetts.These ADAs vary in the average leniency of their prosecution decisions. We find that,for the marginal defendant, nonprosecution of a nonviolent misdemeanor offense leads to large reductions in the likelihood of a new criminal complaint over the next two years.These local average treatment effects are largest for first-time defendants, suggesting that averting initial entry into the criminal justice system has the greatest benefits.
… We find that the marginal nonprosecuted misdemeanor defendant is 33 percentage points less likely to be issued a new criminal complaint within two years post-arraignment (58% less than the mean for complier” defendants who are prosecuted; p < 0.01). We find that nonprosecution reduces the likelihood of a new misdemeanor complaint by 24 percentage points (60%; p < 0.01), and reduces the likelihood of a new felony complaint by 8 percentage points (47%; not significant). Nonprosecution reduces the number of subsequent criminal complaints by 2.1 complaints (69%; p < .01); the number of subsequent misdemeanor complaints by 1.2 complaints (67%; p < .01), and the number of subsequent felony complaints by 0.7 complaints (75%; p < .05). We see significant reductions in subsequent criminal complaints for violent, disorderly conduct/theft, and motor vehicle offenses.
Did you get that? On a wide variety of margins, prosecution leads to more subsequent criminal behavior. How can this be?
We consider possible causal mechanisms that could be generating our findings. Cases that are not prosecuted by definition are closed on the day of arraignment. By contrast, the average time to disposition for prosecuted nonviolent misdemeanor cases in our sample is 185 days. This time spent in the criminal justice system may disrupt defendants’ work and family lives. Cases that are not prosecuted also by definition do not result in convictions, but 26% of prosecuted nonviolent misdemeanor cases in our sample result in a conviction. Criminal records of misdemeanor convictions may decrease defendants’ labor market prospects and increase their likelihoods of future prosecution and criminal record acquisition, conditional on future arrest. Finally, cases that are not prosecuted are at much lower risk of resulting in a criminal record of the complaint in the statewide criminal records system. We find that nonprosecution reduces the probability that a defendant will receive a criminal record of that nonviolent misdemeanor complaint by 55 percentage points (56%, p < .01). Criminal records of misdemeanor arrests may also damage defendants’ labor market prospects and increase their likelihoods of future prosecution and criminal record acquisition, conditional on future arrest. All three of these mechanisms may be contributing to the large reductions in subsequent criminal justice involvement following nonprosecution.
So should we stop prosecuting misdemeanors? Not necessarily. Even if prosecution increases crime by the prosecuted it can still lower crime overall through deterrence. In fact, since there are more people who are potentially deterred than who are prosecuted, general deterrence can swamp specific deterrence (albeit there are 13 million misdemeanors so that’s quite big). The authors, however, have gone some way towards addressing this objection because they combine their “micro” analysis with a “macro” analysis of a policy experiment.
During her 2018 election campaign, District Attorney Rollins pledged to establish a presumption of nonprosecution for 15 nonviolent misdemeanor offenses…After the inauguration of District Attorney Rollins, nonprosecution rates rose not only for cases involving the nonviolent misdemeanor offenses on the Rollins list, but also for those involving nonviolent misdemeanor offenses not on the Rollins list (and for all nonviolent misdemeanor cases)…. the increases in nonprosecution after the Rollins inauguration led to a 41 percentage point decrease in new criminal complaints for nonviolent misdemeanor cases on the Rollins list (not significant), a 47 percentage point decrease in new criminal complaints for nonviolent misdemeanor cases not on the Rollins list (p < .05), and a 56 percentage point decrease in new criminal complaints for all nonviolent misdemeanor cases (p < .05).
It’s unusual and impressive to see multiple sources of evidence in a single paper. (By the way, this paper is also a great model for learning all the new specification tests and techniques in the “leave-out” literature, exogeneity, relevance, exclusion restriction, monotonicity etc. all very clearly described.)
The policy study is a short-term study so we don’t know what happens if the rule is changed permanently but nevertheless this is good evidence that punishment can be criminogenic. I am uncomfortable, however, with thinking about non-prosecution as the choice variable, even on the margin. Crime should be punished. Becker wasn’t wrong about that. We need to ask more deeply, what is it about prosecution that increases subsequent criminal behavior? Could we do better by speeding up trials (a constitutional right that is often ignored!)–i.e. short, sharp punishment such as community service on the weekend? Is it time to to think about punishments that don’t require time off work? What about more diversion to programs that do not result in a criminal record? More generally, people accused and convicted of crimes ought to find help and acceptance in re-assimilating to civilized society. It’s crazy–not just wrong but counter-productive–that we make it difficult for people with a criminal record to get a job and access various medical and housing benefits.
The authors are too sophisticated to advocate for non-prosecution as a policy but it fits with the “defund the police,” and “end cash bail” movements. I worry, however, that after the tremendous gains of the 1990s we will let the pendulum swing back too far. A lot of what counts as cutting-edge crime policy today is simply the mood affiliation of a group of people who have no recollection of crime in the 1970s and 1980s. The great forgetting. It’s welcome news that we might be on the wrong side of the punishment Laffer curve and so can reduce punishment and crime at the same time. But it’s a huge mistake to think that the low levels of crime in the last two decades are a permanent features of the American landscape. We could lose it all in a mistaken fit of moralistic naivete.
1. Politico: The Biden administration is rethinking a costly system of government-run mass vaccination sites after data revealed the program is lagging well behind a much cheaper federal effort to distribute doses via retail pharmacies….The vaccination hubs, which are run by FEMA and staffed in part by National Guard troops and other Pentagon personnel, have administered…about 67,000 shots a day, according to a series of internal FEMA briefing documents and data sets obtained by POLITICO….By comparison, the federal retail pharmacy program reported March 11 it had administered nearly 1 million doses over a single day.
Using the retail pharmacies is what Scott Duke Kominers and I argued for in mid-February in our piece titled, America’s Pharmacies Can Do a Lot More Vaccinations. Good to see the Biden administration is making adjustments. Nothing wrong with the clinics, by the way, only use the pharmacies more.
2. New CDC study of health care workers in the United States shows that the first dose of the Moderna or Pfizer vaccine is 80% effective within two weeks. Big cuts in transmission as well. N.B. not an RCT.
3. One common criticism of delaying the second dose or of using the AstraZeneca vaccine or of making or not making other changes was that this would increase “vaccine hesitancy.” Frankly, in my view this was just an all-purpose rationalization for inaction. I thought that delaying the second dose could just as easily reduce vaccine hesitancy as increase it–not that I knew this would happen, I simply knew what would happen was uncertain. More generally, I thought that we should do the thing designed to save the most lives simpliciter, address vaccine hesitancy directly, and not try to do some complicated bank-shot based on ill-informed psychological speculation. Well Britain did everything that people were worried about–Britain delayed the second dose, used the AstraZeneca vaccine, used the AstraZeneca in the elderly and didn’t halt the use of the AZ vaccine and the result is the least vaccine hesitancy of 26 countries surveyed.
COVID cases are rising in New York, Michigan and New Jersey with most cases coming from the British and New York variants (B.1.1.7, B.1.526). It would be a good idea to flood these zones with vaccines. J&J production should hit 11 million doses this week. Send the J&J vaccine to pharmacies and clinics in these states that are capable of putting a lot of shots in arms quickly.
The Mayor of Charlottesville recently tweeted.
Please explain how building more market rate housing will free up the housing market for low-income citizens. Which low-income citizens will be able to afford to buy or rent a home that’s going to sell to $450,000? New construction will not lower the selling price of older homes….
Fortunately, Bryan Caplan has an excellent explanation, the game of reverse musical chairs.
New housing is usually nice housing, because over time technology improves and capital depreciates. Since richer people are more willing to pay the upcharge for nicer housing, the future residents of new construction are usually well-to-do.
So what do casual observers miss? They miss the big picture: People who move into new construction are moving away from older construction. When they move, those older units become available for others. While those others probably won’t be drastically poorer than those they replace, they tend to be slightly poorer. Think: “one rung down.” When these slightly poorer people move, their prior dwellings will tend to be taken over by those who are a further rung down. And so on, in a great chain reaction. Allowing new construction really does help the whole income distribution.
Since this is hard to visualize, picture a game of musical chairs. With one key difference. A normal game of musical chairs starts out with one chair per person, then subtracts a chair every turn. The result: Faster, aggressive kids push out everyone else, until the fastest, most aggressive kid wins. In my variant game, we start out with fewer chairs than people, then add a chair every turn. The result: Slower and more pacific kids start getting places to sit, until there are enough chairs for everyone.
Both games feature a competitive scramble. In conventional musical chairs, however, the competition gets more and more cutthroat and in the end almost everyone loses. In my reverse musical chairs, in contrast, competition gets milder and milder and in the end everyone wins.
A significant share of vaccine hesitancy is driven by fear of needles, trypanophobia. Adults don’t like to admit a fear of needles and less so that they would avoid a vaccine for fear of a needle. But trypanophobia is common and does reduce flu immunizations:
Avoidance of influenza vaccination because of needle fear occurred in 16% of adult patients, 27% of hospital employees, 18% of workers at long‐term care facilities, and 8% of healthcare workers at hospitals. Needle fear was common when undergoing venipuncture, blood donation, and in those with chronic conditions requiring injection.
Aside from fear of the needle, I think there is also a perception that needles are “serious medicine” and thus anything that comes in needle form must be serious or dangerous. In fact, vaccines are safer than many commonly used drugs that are taken orally.
Needle hesitancy is bad for the hesitant who don’t get protection from COVID and bad for everyone else who are further subject to transmission from unvaccinated carriers.
The best way to alleviate needle hesitancy is to get rid of the needle. Operation Warp Speed made smart investments in a fairly widely range of vaccines (we advised going wider) including a pill vaccine from VaxArt. The VaxArt vaccine has completed a Phase I trial with modest results and is moving into Phase II. Nasal vaccines are in development. The RadVac open science vaccine, for example, is a nasal vaccine available to anyone with a scientific bent willing to give an unapproved vaccine a try. CodaGenix has a nasal vaccine in Phase I trials as does Altimmune.
Aside from ease of delivery, a COVID nasal or oral vaccine may also be better than intramuscular injection because it stimulates the immune system at the first point of viral attack, the mucosal tissues in the nose, mouth, lungs and digestive tract. In addition, the mucosal immune system has some unique elements so you get a potentially stronger immune response more capable of neutralizing the virus quickly.
Operation Warp Speed investments generated trillions in value for billions in cost, a few additional smart investments in accelerating nasal and oral vaccines could pay off highly in mopping up vaccine hesitancy and moving us more quickly to herd immunity. We could even do a human challenge trial with nasal vaccine v. intramusucalar injection. Oral and nasal vaccines will also be great for kids and for booster shots.
Even at this late stage we are spending trillions on stimulus/relief and not enough on investment, especially on highly successful investment in vaccines.
Addendum: I know it probably won’t help but fyi, it’s a painless shot. Nothing to fear! Get a superpower and a donut afterwards. It will be memorable.
Two weeks ago I was bitten by the equivalent of a radioactive spider and now I have superpowers! Including the power of immunity and the power to fly! Awesome. As I said earlier, the SARS-COV-2 virus killed more people this year than bullets “so virus immunity is a much better superpower than bullet immunity!”
I got the J&J vaccine–one of the first in the world to do so–which seemed appropriate as I have been calling for first doses first and the J&J vaccine is single dose. I will probably supplement with Novavax at a later date when supplies are plentiful.
Addendum: Also, I can get free donuts at Krispy Kreme.
This is great.
