Virtually all theories of economic growth predict a positive relationship between population size and productivity. In this paper I study a particular historical episode to provide direct evidence for the empirical relevance of such scale effects. In the aftermath of the Second World War about...

A significant challenge to empirically testing theories of discrimination has been the difficulty of identifying taste-based discrimination and of distinguishing it clearly from statistical discrimination. This paper addresses this problem through a two-part empirical test of taste-based...

A growing theoretical literature emphasizes the role that leaders play in shaping beliefs and social norms. We provide empirical evidence for such 'civic leadership.' We focus on the Forty-Eighters, a group of political refugees from Germany's failed 1848 revolutions, and their role in the...

We combine survey data on British and German immigrants in the US with data on natives in Britain and Germany to estimate the causal effect of migration on educational mobility through cross-national marriage. To control for selective mating, we instrument educational attainment using government...

This paper introduces the concept of "climate matching" as a driver of migration and establishes several new results. First, we show that climate strongly predicts the spatial distribution of immigrants in the US, both historically (1880) and more recently (2015), whereby movers select...

According to the widely known 'culture of honor' hypothesis from social psychology, traditional herding practices are believed to have generated a value system that is conducive to revenge-taking and violence. We test this idea at a global scale using a combination of ethnographic records,...

Folklore is the collection of traditional beliefs, customs, and stories of a community, passed through the generations by word of mouth. This vast expressive body, studied by the corresponding discipline of folklore, has evaded the attention of economists. In this study we do four things that...

Are identities fungible? How do people come to identify with specific groups? This paper proposes a revealed preference approach, using food consumption to uncover ethnic and religious identity choices in India. We first show that consumption of identity goods (e.g. beef and pork) systematically...

This paper documents that many black males experienced a change in racial classification to white in the United States, 1880 - 1940, while changes in racial classification were negligible for other races. We provide a rich set of descriptive evidence on the lives of black men "passing" for...

This paper reviews the literature on gender and culture. Gender gaps in various outcomes (competitiveness, labor force participation, and performance in mathematics, amongst many others) show remarkable differences across countries and tend to persist over time. The economics literature...
