In this paper, we use a sample of almost 30,000 Swedish mono- and dizygotic twins to study the heritability of financial risk-taking. Following a major pension reform in the year 2000, virtually all Swedish adults had to simultaneously make a financial decision affecting post-retirement wealth....

"Beauty contests" are well-studied, dominance-solvable games that generate two interesting results. First, most behavior does not conform to the unique Nash equilibrium. Second, there is considerable unexplained heterogeneity in behavior. In this work, we explore the relationship between beauty...

Empirical evidence suggests that people on average overestimate their own ability in a variety of circumstances. Little is known, however, about the origins of such overconfidence. To shed some light on this issue, we use the classic twin design to estimate the genetic and environmental...

Individuals differ in how they compose their investment portfolios, yet empirical models of portfolio risk typically only account for a small portion of the cross-sectional variance. This paper asks if genetic variation can explain some of these individual differences. Following a major pension...

We test whether generosity is related to political preferences and partisanship in Canada, Sweden, the United Kingdom and the United States using incentivized dictator games. The total sample consists of more than 5,000 respondents. We document that support for social spending and redistribution...
