The political economy of Swine flu vaccine allocation

by  Tyler Cowen in

Previous research has isolated the effect of “congressional dominance” in explaining bureaucracy-related outcomes. This analysis extends the concept of congressional dominance to the allocation of H1N1, or swine flu, vaccine doses. States with Democratic United States Representatives on the relevant House oversight committee received roughly 60,000 additional doses per legislator during the initial allocation period, though this political advantage dissipated after the first 3 weeks of vaccine distribution. As a result political factors played a role in determining vaccine allocation only when the vaccine was in particularly short supply. At-risk groups identified by the Centers for Disease Control (CDC), such as younger age groups and first responders, do not receive more vaccine doses, and in fact receive slightly fewer units of vaccine.

David Splinter responds to Saez and Zucman

by  Tyler Cowen in

When estimating income inequality with tax data, accounting for missing income presents many challenges. Researchers have adopted different approaches to address these challenges. Saez and Zucman (2020) discuss differences between the national income distributions of Piketty, Saez, and Zucman (PSZ, 2018) and Auten and Splinter (AS, 2019a). Saez and Zucman also make updates to their estimates for retirement income, partially responding to one of the concerns raised in AS. In this reply, I explain that SZ only partly correct this problem and do not address other issues raised by AS. For the allocation of underreported income—the most consequential difference between AS and PSZ—I show that the AS approach conforms with special audit studies in five ways, while the PSZ approach is inconsistent with them. I also provide historical background on the two projects, respond to technical points raised, and discuss estimates of tax progressivity.

Sweden Covid-19 update

by  Tyler Cowen in

Do not judge Sweden until the autumn. That was the message from its state epidemiologist Anders Tegnell in May and through the summer as he argued that Sweden’s initial high death toll from Covid-19 would be followed in the second wave by “a high level of immunity and the number of cases will probably be quite low”.

Now the autumn is here, and hospitalisations from Covid-19 are currently rising faster in Sweden than in any other country in Europe, while in Stockholm — the centre for both the first and second waves in the country — one in every five tests is positive, suggesting the virus is even more widespread than official figures suggest.

Even Sweden’s public health agency admits its earlier prediction that the country’s Nordic neighbours such as Finland and Norway would suffer more in the autumn appears wrong. Sweden is currently faring worse than Denmark, Finland and Norway on cases, hospitalisations and deaths relative to the size of their population.

…The number of patients hospitalised with Covid-19 is doubling in Sweden every eight days currently, the fastest rate for any European country for which data is available. Its cases per capita have sextupled in the past month to more than 300 new daily infections per million people, close to the UK and way ahead of its Nordic neighbours.

Here is more from Richard Milne at the FT.  To be clear, it seems that many of the Swedish deaths are due to a “dry tinder” effect, so in relative terms they are not doing as much worse than you might think. Other parts of Europe may well catch up to them, at least on a “tinder-adjusted” basis.  But if you are just asking which predictions of which model are being vindicated here, it is that the herd immunity obtained through a partial neutralization of super-spreaders is temporary rather than permanent.

Source here. And Swedish deaths seem to be 40% of the U.S. equivalent.

To be clear, I did not predict this (or its opposite), but rather for many months I have been saying we need more data from Sweden to draw a conclusion.  Now we have more data.

Paige Harden on Genetic Differences and the Left

by  Alex Tabarrok in

Paige Harden, the left-leaning behavioral geneticist, brings the fire in comments on an AEON article about her work:

In this article, Erik Parens urges me and other scientists working in the field of social genomics to “curb [our] optimism” regarding how genetic discoveries could be used to advance progressive and egalitarian social goals. In my view, however, it is Parens and other critics of social genomics who need to curb their optimism, in two ways.

First, Parens is overly optimistic that social science can ever hope to be successful without genetics. In reality, social scientists have failed, time and time again, to produce interventions that bring about lasting improvements in people’s lives. There are many reasons for that failure. But one reason is that many scientists continue to engage in what the sociologist Jeremy Freese has called a “tacit collusion” to avoid reckoning, in their research designs and in their causal inferences, with the fact that people are genetically different from one another.

All interventions and policies are built on a model of how the world works: “If I change x, then y will happen.” A model of the world that pretends all people are genetically the same, or that the only thing people inherit from their parents is their environment, is a wrong model of how the world works. The more often our models of the world are wrong, the more often we will continue to fail in designing interventions and policies that do what they intend to do. The goal of integrating genetics into the social sciences is not to design boutique educational interventions tailored for children’s genotypes. It is to help rescue us from our current situation, where most educational interventions tested don’t work for anyone. This track record of failure plays directly into the hands of a right-wing that touts the ineffectiveness of intervention as evidence for its false narrative of genetic determinism.

Second, Parens and other critics are overly optimistic that their strategy of disapproval, discouragement, and disavowal of genetic research will be effective in neutralizing the pernicious ideologies of the far-right. What is the evidence that this strategy actually works? Herrnstein and Murray published “The Bell Curve” when I was 12 years old; Murray published “Human Diversity” when I was 37 years old; and in all that time, the predominant response from the political left has remained pretty much exactly the same – emphasize people’s genetic sameness, question the wisdom of doing genetic research at all, urge caution. Yet, the far-right is ascendant. In my view, the left’s response to genetic science simply preaches to its own choir. Meanwhile, this strategy of minimization allows right-wing ideologues to offer to “red-pill” people with the “forbidden knowledge” of genetic results.

What the left hasn’t done (yet) is formulate a messaging strategy that (a) reconciles the existence of human genetic differences with people’s moral and political commitments to human equality, and (b) is readily comprehensible outside the confines of the ivory tower. Reminding people that genes are a source of luck in their lives has the potential to be that message. Parens characterizes me as making a “generous hearted but large leap” to expect that portraying genes as luck will change people’s minds, but economic research suggests that reminding people of the role of luck in their lives does, in fact, make them more supportive of redistribution.

Overall, this article portrays me and others working in this space as “soft-pedaling” the dangers of social genomics being appropriated by the far right. But I am fully cognizant of the dangers. Parens is the one who is soft-pedaling. He is soft-pedaling the enormous damage done to progress in psychology, sociology, and other social sciences – fields that are tasked with improving people’s lives – by their refusal to engage with genetics. And, he is soft-pedaling the danger of simply continuing the left’s decades-old, easily-“red-pilled” rhetorical strategy at a time with right-wing ideologies are on the rise globally.

Not disappearing after November 3rd

by  Tyler Cowen in

Via Scott Gottlieb.  And how about North Dakota?  It is a low population state, but if all of the United States were putting in a comparable Covid performance we would be having about 12,500 Covid deaths a day.  That is certainly not my prediction, but it is one way to think about what could happen from a very bad policy and social norms response.  Is that the road we wish to be veering towards?

Secularization and the Tribulations of the American Working-Class

by  Tyler Cowen in

That is a work in progress by Brian Wheaton, job market candidate from Harvard University.  Here is the abstract:

Over the past several decades, working-class America has been plagued by multiple adverse trends: a sharp increase in social isolation, an even sharper increase in single parenthood, a decline in male labor force participation rates, and a decline in generational economic mobility – amongst other things.  Material economic factors have been unable to fully explain these phenomena, often yielding mixed results or – in some cases, such as that of single parenthood – lacking explanatory power altogether.  I study the decline in religiosity and, using a shift-share instrument leveraging the fact that different religious denominations are declining at different rates, I find that religious decline has a strong adverse effect on the aforementioned variables.  The effects are not weakened by including other potential explanatory factors (such as China trade shocks and variation in public assistance).  I present evidence that, to the extent reverse causality exists, it creates bias in the opposite direction of my estimates.  These findings are also robust to several alternative instruments, including the repeal of the state blue laws banning retail activity on Sundays and the Catholic church scandals of the 2000s.  Two instruments – the blue laws and the state anti-evolution laws mandating teaching of creationism in school – allow me to ascertain whether the effect proceeds through religious attendance or beliefs.  I find that, for most outcomes, the bulk of the effect is driven by religious attendance.

To be clear, that is not Brian’s job market paper, which covers “Laws, Beliefs, and Backlash.” Or you might wish to try these results on corporal punishment in schools (with Maria Petrova and Gautam Rao):

We find that the presence of corporal punishment in schools increases educational attainment, increases later-life social trust and trust in institutions, and leads to less authoritarian attitudes toward child-rearing, and greater tolerance of free speech. Additionally, exposure to corporal punishment in school decreases later-life crime. We find no effects on mental or physical health.

Here is his paper about flat tax reform in Eastern Europe:

Using static and dynamic difference-in-differences approaches, I find that the flat tax reforms increase annual GDP growth by 1.36 percentage points for a transitionary period of approximately one decade.

I praise the scholarship and courage of Brian N. Wheaton.

Are body cameras effective for constraining police after all?

by  Tyler Cowen in

Controversial police use of force incidents have spurred protests across the nation and calls for reform. Body-worn cameras (BWCs) have received extensive attention as a potential key solution. I conduct the first nationwide study of the effects of BWCs in more than 1,000 agencies. I identify the causal effects by using idiosyncratic variation in adoption timing attributable to administrative hurdles and the lengthy process to the eventual adoption at different agencies. This empirical strategy addresses limitations of previous studies that evaluated BWCs within a single agency; in a single-agency setting, the control group officers are also indirectly affected by BWCs because they interact with the treatment group officers (spillover), and agencies that give researchers access may fundamentally differ from other agencies (site-selection bias). Overcoming these limitations, my multi-agency study finds that BWCs have led to a substantial drop in the use of force, both among whites and minorities. Nationwide, they reduce police-involved homicides by 43%. Surprisingly, I do not find evidence that BWCs are associated with de-policing. Examining social media usage data from Twitter as well as data on the Black Lives Matter (BLM) movement, I find that after BWC adoption, public opinion toward the police improves. These findings imply that BWCs can be an important tool for improving police accountability without sacrificing policing capabilities.

The local amenities effect of Prohibition

by  Tyler Cowen in

Comparing same-state early and late adopters of county dry laws in a difference-in-differences design, we find that early Prohibition adoption increased population and farm real estate values. Moreover, we find strong effects on farm productivity consistent with increased investment due to a land price channel. In equilibrium, the amenity change disproportionately attracted immigrants and African-Americans.

Micro-hemorrhages and the importance of vaccination

by  Tyler Cowen in

Neurological manifestations are a significant complication of coronavirus infection disease-19 (COVID-19). Understanding how COVID-19 contributes to neurological disease is needed for appropriate treatment of infected patients, as well as in initiating relevant follow-up care after recovery. Investigation of autopsied brain tissue has been key to advancing our understanding of the neuropathogenesis of a large number of infectious and non-infectious diseases affecting the central nervous system (CNS). Due to the highly infectious nature of the etiologic agent of COVID-19, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), there is a paucity of tissues available for comprehensive investigation. Here, we show for the first time, microhemorrhages and neuropathology that is consistent with hypoxic injury in SARS-CoV-2 infected non-human primates (NHPs). Importantly, this was seen among infected animals that did not develop severe respiratory disease. This finding underscores the importance of vaccinating against SARS-CoV-2, even among populations that have a reduced risk for developing of severe disease, to prevent long-term or permanent neurological sequelae. Sparse virus was detected in brain endothelial cells but did not associate with the severity of CNS injury. We anticipate our findings will advance our current understanding of the neuropathogenesis of SARS-CoV-2 infection and demonstrate SARS-CoV-2 infected NHPs are a highly relevant animal model for investigating COVID-19 neuropathogenesis among human subjects.

That is from new Fast Grants supported research by Tracy Fischer, et.al. And here are some related earlier results from Kabbani and Olds.  Here are some more general recent results about brain damage.

How bad are these micro-hemorrhages anyway?  I don’t know!  You may notice I have hardly lunged at the “permanent damage” papers that have been coming out on Covid (in fact many of them already have collapsed or not replicated).  But there are genuine reasons for caution, these results do not seem to be collapsing, and Covid-19 is not just a bunch of people trying to make a mountain out of a molehill.  And “exposing the young” decisions should not be taken lightly either.  The people who are very cautious about reopening may be too risk-averse given realistic alternatives, but they are not all just statists, Trump haters, lazy teachers’ unions, and so on.  There are very genuine concerns here.

Redistribution!

by  Tyler Cowen in

Depressive symptoms increased from before to during COVID-19 and life satisfaction decreased. Individuals with higher education experienced a greater increase in depressive symptoms and a greater decrease in life satisfaction from before to during COVID-19 in comparison to those with lower education. Supplemental analysis illustrates that income had a curvilinear relationship with changes in well-being, such that individuals at the highest levels of income experienced a greater decrease in life satisfaction from before to during COVID-19 than individuals with lower levels of income.

Here is the full research paper, by Connie R. Wanberg et.al., with other interesting results including on causal mechanisms.  Via the excellent Kevin Lewis.
