In this paper we study the finite sample and asymptotic properties of various weighting estimators of the local average treatment effect (LATE), several of which are based on Abadie (2003)’s kappa theorem. Our framework presumes a binary endogenous explanatory variable (“treatment”) and a...

This paper shows that import exposure affects voting behavior because it affects local labor markets. We develop a new framework for mediation analysis where one instrumental variable is sufficient to identify three causal effects. Using German data from 1987–2009, we find that import exposure...

Early in their formation, modern nation-states face internal conflicts that impede their economic development. This paper examines the role of national identity in helping modern states overcome such conflicts to provide public goods and grow. We develop a model in which the population can...

The consequences of successful public health interventions for social violence and conflict are largely unknown. This paper closes this gap by evaluating the effect of a major health intervention – the successful expansion of anti-retroviral therapy (ART) to combat the HIV/AIDS pandemic –...

An emerging literature on the geography of bohemians argues that a region's lifestyle and cultural amenities explain, at least partly, the unequal distribution of highly qualified people across space, which in turn, explains geographic disparities in economic growth. However, to date, there has...

We present new data documenting medieval Europe's Commercial Revolution using information on the establishment of markets in Germany. We use these data to test whether medieval universities played a causal role in expanding economic activity, examining the foundation of Germany's first...

This research explores the economic causes and consequences of language structures. It advances the hypothesis and establishes empirically that variations in pre-industrial geographical characteristics that were conducive to higher return to agricultural investment, larger gender gap in...

This paper studies the impact of Muslim rule on human capital development. Using a unique novel dataset containing yearly data on Muslim presence in the period 711-1492 and literacy rate in 1900 for about 7500 municipalities in Spain, we estimate the local impact of the length of Muslim rule in...

Do knowledge intense jobs exhibit lower gender gaps in wages? Here we use a linked employeremployee dataset of the entire Brazilian formal labor force to study the relationship between gender wage gaps and the knowledge intensity of industries and occupations. We find that employees in...
