The last few decades witnessed a dramatic change in public opinion towards gay people. This paper studies the hypothesis that the AIDS epidemic was a shock that changed the incentive to “come out” and that the ensuing process of mobilization and endogenous political process led to cultural...

This study examines the variation in educational outcomes across and within countries using the TIMSS mathematics tests. It documents the wide cross-country variation in the level and dispersion of test scores. Countries with the highest test scores are those with the least inequality in scores,...

We explain how the decentralization of fiscal responsibility among Brazilian states between 1889 and 1930 promoted a unequal expansion in public schooling. We document how the variation in state export tax revenues, product of commodity booms, explains increases in expenditures on education,...

We overview the use of field experiments in labor economics. We showcase studies that highlight the central advantages of this methodology, which include: (i) using economic theory to design the null and alternative hypotheses; (ii) engineering exogenous variation in real world economic...

We present evidence on whether and how a household's behavior is influenced by the presence and characteristics of its extended family. Using household panel data from the Progresa program in rural Mexico, we exploit information on the paternal and maternal surnames of heads and spouses in...

We exploit a unique combination of administrative sources and survey data to study the match between firms and managers. The data includes manager characteristics, such as risk aversion and talent; firm characteristics, such as ownership; detailed measures of managerial practices relative to...

Why does illegal trade often flourish without formal enforcement, but sometimes fail? Why do illegal trade-reducing policies often fail? Why do States often appear to tolerate illegal trade? A model of trade with cops and robbers provides answers. `Safety in numbers' is a key element: the...

Weak states enable private enforcement but it does not always fade away in the presence of strong states. We develop a general equilibrium model of the market organization of enforcers (self-enforcers, competitive specialized enforcers or monopoly) who defend endowments from predators. We...

We present evidence on the labor supply of CEOs, and on whether family and professional CEOs differ on this dimension. We do so through a new survey instrument that allows us to codify CEOs' diaries in a detailed and comparable fashion, and to build a bottom-up measure of CEO labor supply. The...

We design a field experiment to study how the allocation of authority between frontline procurement officers and their monitors affects performance both directly and through the response to incentives. In collaboration with the government of Punjab, Pakistan, we shift authority from monitors to...
