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.
