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...

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...

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...

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 many countries, pension funds based on individual accounts have been affected by high operating costs. Contract theory helps to unravel the nature of such problems: managers of pension funds have strong incentives to manipulate market expectations about their capacity through wasteful...

We model a two-region country where value is created through bilateral production between masses and elites (bourgeois and landowners). Industrialization requires the elites to finance schools and the masses to attend them. Schooling raises productivity, particularly for matches between masses...

Online marketplaces for remote labor services allow workers and firms to contract with each other directly. Despite this, a large fraction of the workforce is affiliated with small, autonomous intermediary organizations that are widespread within these markets. This paper shows that...

Online markets for remote labor services allow workers and firms to contract with each other directly. Despite this, intermediaries - called outsourcing agencies - have emerged in these markets. This paper shows that agencies signal to employers that inexperienced workers are high quality....

We use a mechanism–design approach to study a team whose members choose a joint project and exert individual efforts to execute it. Members have private information about the qualities of alternative projects. Information sharing is obstructed by a trade–off between adaptation and...

This paper examines sorting into interracial friendships at selective universities. We show significant friendship segregation, particularly for blacks. Indeed, black friendships are no more diverse in college than in high school despite the colleges blacks attend having substantially smaller...
