Social scientists have long speculated about individuals' tendencies to misrepresent their preferences in order to affect the outcome of social choice mechanisms. The fact that preference orderings are generally unobserved, however, has made it very difficult to document strategic behavior...

Adolf Hitler's seizure of power was one of the most consequential events of the twentieth century. Yet, our understanding of which factors fueled the astonishing rise of the Nazis remains highly incomplete. This paper shows that religion played an important role in the Nazi party's electoral...

Backward induction is a cornerstone of modern game theory. Yet, laboratory experiments consistently show that subjects fail to properly backward induct. Whether these findings generalize to other, real-world settings remains an open question. This paper develops a simple model of sequential...

Social scientists have long speculated about the extent of agents' rationality, especially in the context of voting. However, existing attempts at classifying voters as (ir)rational have been hampered by the fact that preference orderings and, thus, optimal strategies are generally unobserved....

Since the 1960s both crime rates and the share of immigrants among the American population have more than doubled. Almost three quarters of Americans believe immigration increases crime, yet existing academic research has shown no such effect. Using panel data on US counties from 1980 to 2000,...

Over the past 40 years, the fraction of mixed race black-white births has increased nearly nine-fold. There is very little empirical evidence on how these children fare relative to their single-race counterparts. This paper describes basic facts about the behaviors and outcomes of black-white...

Few theories in the social sciences have gained more widespread acceptance than Max Weber’s The Protestant Ethic and the Spirit of Capitalism—despite a lack of conclusive empirical evidence. At the core of Weber’s theory lies a connection between Protestantism and attitudes toward work....

We develop a Roy model of social interactions in which individuals sort into peer groups based on comparative advantage. Two key results emerge: First, when comparative advantage is the guiding principle of peer group organization, the effect of moving a student into an environment with...

Few studies in the social sciences have spurred more controversy than Max Weber’s The Protestant Ethic and the Spirit of Capitalism. At the core of Weber’s theory lies a connection between Protestantism and attitudes toward work. Using micro-data from contemporary Germany, this paper...

Since the 1960s both crime rates and the share of immigrants among the American population have more than doubled. Almost three quarters of Americans believe immigration increases crime, yet existing academic research has shown no such effect. Using panel data on US counties from 1980 to 2000,...
