This paper develops a one sector, two-input model with endogenous human capital formation. The two inputs are two types of skilled labor: "engineering," which exerts a positive externality on total factor productivity, and "law", which does not. The paper shows that a marginal prospect of...

This paper asks whether population growth is conducive to the sustainability of cooperation. A simple model is developed in which farmers who live around a circular lake engage in trade with their adjacent neighbors. The payoffs from this activity are governed by a prisoner's dilemma "rule of...

This paper adds three dimensions to the received literature: it models migration when the individuals' preferences regarding their relative income are ordinal, it works out the resulting spatial steady-state distribution of the individuals, and it shows that the aggregate of the individuals'...

We investigate the impact of the imposition of sanctions for employing illegal migrants on the welfare of native workers. Our analysis is based on the premise that in response to such sanctions, managers in a firm may be reassigned from supervision of production to verification of the legality...

This paper studies the growth dynamics of a developing country under migration. Assuming that human capital formation is subject to a strong enough, positive intertemporal externality, the prospect of migration will increase growth in the home country in the long run. If the external effect is...

We draw a distinction between the social integration and economic assimilation of migrants, and study an interaction between the two. We define social integration as blending into the host country’s society, and economic assimilation as acquisition of human capital that is specific to the host...

We relate to others in two important ways: we care about others, and we care about how we fare in comparison to others. In some contexts, these two forms of relatedness interact. Caring about others can conveniently be labeled altruism. Caring about how we fare in comparison with others who fare...

We present a theory that systematically and causally links the well-being of native inhabitants with variation in the extent of the assimilation of migrants. Recent empirical findings are yielded as predictions of the theory.

A migration network is modeled as a mutually beneficial cooperative agreement between financially-constrained individuals who seek to finance and expedite their migration. The cooperation agreement creates a network: "established" migrants contract to support the subsequent migration of others...

We document and suggest a rationale for the durability of seasonal migration from Poland to Germany, a phenomenon persisting for more than a century. We refer to the role of the tradition of engaging in seasonal migration as a force that helped invigorate the process and contribute to its...
