We study a credence goods problem - that is, a moral hazard problem with non-contractible outcome - where altruistic experts (the agents) care both about their income and the utility of consumers (the principals). Experts' preferences over income and their consumers' utility are convex, such...

We analyze individuals with heterogeneous time-inconsistent preferences that consume sin goods and make a savings decision. A government may tax the sin good and provide mandatory health insurance. Due to time-inconsistency, the individual sin good and savings choices in ict internalities. Due...

This paper examines the determinants of internal migration in a context where wages tend to be rather inflexible at a regional scale so that regional labor demand shocks have a prolonged impact on employment rates. Regional income differentials, then, reflect both regional pay and employment...

Borjas (1987, 1991 and 1994) developed the self-selection theory, applying Roy's model (1951) to migration studies. He establishes that the characteristics of migrants in terms of skills and abilities are driven by wage distribution differences between the host country and home. In this regard,...

Career progression is often associated with migration and/or industry change, but the relationship between the two, and their effect on the earnings and career satisfaction of recent graduates are not well understood. We analyse the relationship between migration and inter-industry mobility...

We develop a model of a city populated by heterogeneous agents. Agents self-select into entrepreneurship, and entrepreneurs set up firms which hire workers. We characterize the equilibrium matching between firms and workers, as well as the within-city assignment of agents to locations. We then...

About 1.4 million refugees and irregular migrants arrived in Europe in 2015 and 2016. We model how refugees and irregular migrants are self-selected. Using unique datasets from the International Organization for Migration and Gallup World Polls, we provide the first large-scale evidence on...
