Exploiting the staggered timing of homeland establishment in a cross-cohort identification strategy, we find that moving to the home-lands during childhood significantly reduces educational attainment, labor earnings, and employment rates in adulthood. The data suggest an important role for place effects. Moving to the homelands in childhood implies greater exposure to poorer neighborhoods, and it disproportionally reduces human capital attainment.

In the world’s largest fishery, the regulator attempts to reduce the harvesting of juvenile fish by temporarily closing areas where the share of juvenile catch is high. By combining administrative microdata with biologically richer data from fishing firms, I isolate variation in closures that is due to the regulator’s lower-resolution data. I estimate substantial temporal and spatial spillovers from closures. Closures increase total juvenile catch by 48 percent because closure announcements implicitly signal that fishing before, just outside, and after closures is high productivity.

Our empirical short-lived changes to renewables regulation in the Spanish market and shows that switching from full-price exposure to fixed prices caused a 2–4 percent reduction in the average price-cost markup.

Though the opportunity cost of filing falls, the fraction of meritorious claims increases—a sufficient condition for rising discrimination under plausible assumptions. Second, we repurpose data from hiring correspondence studies conducted across different cities and time periods during the recovery from the Great Recession.
