This paper provides evidence that local social interactions within etnic groups may explain the puzzling variations in labour-market outcomes across individuals. Peer effects work first by creating pressure on labor-market participation, second, by conveying information about job opportunities...

Economists have a well-developed theory of value but the theory of why people hold the values they do is rudimentary at best. In spite of the fact that it is common to argue that values are important, most work on values is normative and the positive theory of values is relatively under-...

This paper examines the determinants of self-employment success for microcredit borrowers. Theories of social capital and neighbourhood effects are integrated in an attempt to account for earnings differentials amongst a unique sample of microfinance borrowers. The paper posits that social...

We present a theory of ethnic conflict in which coalitions formed along ethnic lines compete for the economy’s resources. The role of ethnicity is to enforce coalition membership: in ethnically homogeneous societies members of the losing coalition can defect to the winners at low cost, and...

There is a lot of evidence that identity matters for behavior. There is a widespread belief that societies will function better if they manage to establish a common sense of identity among the population. And there are also contemporary fears that this common identity is threatened in several...

The issue of the nature of the altruism inherent in blood donation and the perverse effects of financial rewards for blood and/or organ donation has been recently revisited in the economic literature with limited consensus.

We investigate the role of manipulation in a model of opinion formation where agents have opinions about some common question of interest. Agents repeatedly communicate with their neighbors in the social network, can exert some effort to manipulate the trust of others, and update their opinions...
