Who gains from this? "We find considerable evidence that graduate students are excessively optimistic regarding the state of academic job market, their chances to become faculty, and their chances to publish in the very best scientific journals."

Can the effect of street lighting on public safety endure over time? In a new paper w/ @dmitre88, @tahamonster & @jd_lerner, we report results from a 3 yr follow-up of the first RCT of street lighting. Large treatment effects endure three years later! 👇

The top-line result of this study of microlending is that it helps women start businesses and earn income. But unfortunately, the businesses they are starting are often multilevel marketing businesses, where you mostly make money by signing up other people. (1/7)

It’s been more than 2 years since schools began shutting down due to COVID! In a new review, @lhmosco and I look at actual estimates (not projections) of learning loss and/or dropout rates from 27 countries.

The 12 Fed regional banks published 4,715 working papers between Jan 2006 and June 2021. NY (not surprisingly) and St. Louis (!) were the most prolific. via @cconces & @CParaSkinner papers.ssrn.com/sol3/papers.cf…

There is a very bad idea popular in the humanities, among historians, and in popular culture that trying to massively extend human lifespans is immoral hubris, & that more generally, society must be short-signed due to the urgency of our current problems. nytimes.com/2022/03/15/pod…

Anup Malani@anup_malani
Many journals in economics require exclusive submission: a submitted paper not be under consideration elsewhere.
Given the long review times at econ journals, this delays publication of research. Given fixed tenure clocks, it creates large career risk for junior economists....

Nice one, @ZachWeiner. Actually, it's standard advice for PhD students that one should not worry about getting perfect grades, because it's better to spend time on research.
