Explaining the evolution and maintenance of cooperation among unrelated individuals is one of the fundamental problems in biology and the social sciences. Recent experimental evidence suggests that altruistic punishment is an important mechanism to maintain cooperation among humans. In this...

This paper introduces new experimental designs to enrich understanding of conditional cooperation and punishment in public good games. The key to these methods is to elicit complete contribution or punishment profiles using the strategy method. It is found that the selfish bias in conditional...

We consider rent-seeking contests between and within two equal-sized groups. Each group adopts one of three sequences: first internal then external contest, first external then internal contest, and simultaneous internal and external contests. Groups cannot unilaterally postpone a contest...

This paper analyzes whether the propensity to secede by subnational regions responds mostly to differences in income per capita or to distinct identities. We explore this question in a quantitative political economy model where people's willingness to finance a public good depends on their...

The effect of negative shifts in public opinion on the economic lives of minorities is unknown. We study the role of racial bias in the U.S. labor market by investigating sudden changes in public opinion about Asians following the anti-Chinese rhetoric that emerged with the COVID-19 pandemic,...

This paper studies unethical behavior by groups and provides systematic evidence on how lying decisions are affected by group size and group gender composition. We conduct an online experiment with 1,677 participants (477 groups) where group members can communicate with each other via a novel...

We analyze the topical question of how the compensation of elected politicians affects the set of citizens choosing to run. To this end, we develop a sparse and tractable citizen-candidate model of representative democracy with ability differences, informative campaigning and political parties....

Public opinion influences politicians, and therefore influences public policy decisions. What are the roles of self-interest, knowledge, and ideology in public opinion formation? And how do people learn about economic issues? Using a new, specially-designed survey, we find that most respondents...
