We study the migration policy set by a welfare maximizing government in a model where immigrant workers differ in their skills and are imperfectly matched with heterogenous occupations. The policy fixes a minimum skill level for legal migrants, and foreign workers that fall below it can only...

We propose a theoretical framework for analyzing the problems associated to unilateral immigration policy in receiving countries and for evaluating the grounds for reform of international institutions governing immigration. We build a model with multiple destination countries and show that...

We build a simple model of self-selection into migration and immigration policy determination. We first show that the effect of any immigration policy can be decomposed into a size and a composition effect. We then explore how the optimal policy may change once the latter effect is considered.

International migration is maybe the single most effective way to alleviate poverty at a global level. When a given host country allows more immigrants in, this creates costs and benefits for that particular country as well as a positive externality for all those (individuals and governments)...

We investigate the relationship between remittances and migrants' education both theoretically and empirically, using original bilateral remittance data. At a theoretical level we lay out a model of remittances interacting migrants' human capital with two dimensions of immigration policy:...

Several destination countries still adopt general immigration policies, and are characterized by lower returns to education than the countries of origin of the migrants. These two stylized facts challenge the literature on the beneficial brain drain which demonstrates that migration can increase...

Increasing international migratory flows in the last four decades is one of the most visible manifestations of the globalization process. In spite of its potential positive effect on global efficiency and well-being, little progress has been made in designing and promoting a normative and...

We set up a theoretical model to analyze the implications of coordination of immigration policies among destination countries. The model contains two types of spillovers between destination countries: a terms-of-trade externality and a welfare-policy externality. We show that while coordination...

This paper proceeds in threesteps. First it starts by setting the economic and demographic stage on which theenlargement process is to take place. Second, it identifies and analyzes the likeliness –andtypes– of migratory flows within an enlarged Union in the case of a full enlargement...
