Reasons to grant immigration amnesties include the intention to reduce the weight of the informal sector and the attempt to identify employers of undocumented workers. However, it is incontestable that potential fiscal gains are important: tax revenues are crucial in all kinds of amnesties....

Natural disasters have been shown to produce effects on social capital, risk and time preferences of victims. We run experiments on altruistic preferences on a sample of Sri Lankan microfinance borrowers affected/unaffected by the tsunami shock in 2004 at a 7-year distance from the event (a...

This paper studies the optimal fiscal treatment of addictive goods (cigarettes, drugs, fatty foods, alcohol, gambling etc.). It shows that, when agents have private information about their productivity levels and their degree of rationality, the Atkinson and Stiglitz result of optimal uniform...

This paper studies how incentives are affected by intention-based reciprocity preferences when the principal hires many agents. Our results describe the agents' psychological attitudes required to sustain a given strategy profile. We also show that hiring reciprocal agents to implement a first...

We present a dynamic OLG model of educational signaling, inequality and mobility with missing credit markets. Agents are characterized by two sources of unobserved heterogeneity: ability and parental income, consistent with empirical evidence on returns to schooling. Both quantity and quality of...
