Highlights

► We investigate evidence linking teacher supply to better educational outcomes. ► Presence of a girls' secondary school (GSS) increases the supply of skilled women. ► With greater supply but limited labor mobility, these women have lower wages. ► The existence of a GSS increases the probability of private school in the village. ► Public investments in girls' secondary education crowd in private capital.

Highlights

► We provide field experimental evidence on trust discrimination at the city level. ► Trust varies substantially depending on the residential district of the trading partner. ► We identify economic status as the main determinant of trust discrimination. ► There is an in-group effect in trust discrimination: people trust more if their partner lives in the same district. ► The in-group effect is, at least partly, driven by more accurate beliefs about behavior of in-group members.

Highlights

► Many governments set aside procurement contracts for small businesses. ► We examine how much set-asides increase government procurement costs. ► We find that many small businesses would exit the procurement market without set-asides. ► The resulting lack of competition would raise government procurement costs,more than offsetting production cost inefficiency.

Highlights

► We document substantial variation in house price growth within a city. ► We develop a model that links house price growth and gentrification. ► A key ingredient in our model is individuals like to live next to richer neighbors. ► Richer neighborhoods expand at borders when positive city-wide demand shocks occur. ► We find strong empirical support for the model's predictions.

Highlights

► Using data on North Carolina teachers, I replicate previous findings. ► I find higher returns to later career teaching experience for mathematics. ► I find twice as much dispersion in initial teacher quality as previously estimated. ► I find a pattern of negative teacher selection.

Highlights

► The introduction of broadcast TV in the US led to lower political polarization. ► The expansion of radio in the US was also correlated with depolarization. ► Two possible channels: effects on political motivation, and on ideological views ► Effect of TV is consistent with the ideology effect. ► Effect of radio is consistent with motivation effect.

Highlights

► International agreements are negotiated between elected national delegates. ► Any international agreement generates distributive effects. ► An agreement may not be reached, depending on equity rules and income distribution. ► The elections of delegates depend on intra- and international income inequalities.
