When considering engaging in conflict to secure control of a resource, a group needs to predict the amount of post-conflict leakage due to infiltration by members of losing groups. We use this insight to explain why conflict often takes place along ethnic lines, why some ethnic groups are more...

A fundamental issue for economists is what determines civil conflict. One unsettled question is the relative importance of political freedoms versus economic development. This paper takes a new approach to provide an answer by using micro-data based on surveys of revolutionary preferences of...

The composer has historically been at the top of the tree in the music industry; most royalties due to artists flow back to composers/songwriters rather than performers. Over the last few decades, the enactment of stronger performers’ rights has sought to redress this historical imbalance by...

Fifteen per cent of British babies are now born to parents who are neither cohabiting nor married. Little is known about non-residential fatherhood that commences with the birth of a child. Here, we use the Millennium Cohort Study to examine a number of aspects of this form of fatherhood....

This paper emphasizes the two-way causality between the provision of unemployment insurance and the cultural transmission of work ethic. Values affect the size of the moral-hazard problem and, hence, the policy to be implemented. Conversely, when parents rationally choose how much effort to...

In countries with high levels of ethnic diversity, “nation building” has been proposed as a mechanism for integration and conflict reduction. We find no evidence of lower intensity of national sentiment in more ethnically fragmented countries or in minority groups. National feelings in a...

Existing studies of trust formation in U.S. metropolitan areas have found that trust is lower when there is more income inequality and greater racial fragmentation. I add to this literature by examining the role of income inequality between racial groups (racial income inequality). I find that...

We develop a model capturing habit formation, projection bias, and present bias in an intertemporal-choice setting, and conduct a field experiment to identify its main parameters. We elicit subjects' pre- and post-treatment predictions of post-treatment gym attendance, using a habit-formation...

While a large social-choice-theoretic literature discusses the aggregation of individual judgments into collective ones, there is relatively little formal work on the transformation of individual judgments in group deliberation. I develop a model of judgment transformation and prove a baseline...
