This paper analyzes how population aging affects immigration policy in rich industrialized countries. It sets up a two-period model of a representative democracy with two overlapping generations. The government's preferred immigration rate increases with the share of retirees in the population....

Minorities, such as ethnic and immigration groups, have often been subject to exclusion through labor market discrimination, residential and employment segregation policies, business ownership regulations, restrictions on political participation, access to public services and more. This paper...

In the political debate people express the idea that immigrants are good because they can help pay for the old. The paper explores this idea in a dynamic political-economy setup. We characterize sub-game perfect Markov equilibria where immigration policy and pay-as-yougo (PAYG) social security...

The paper examines the problem of aggregating infinite utility streams with a social welfare function which respects the Anonymity and Weak Pareto Axioms. It provides a complete characterization of domains (of the one period utilities) on which such an aggregation is possible. A social welfare...

It is known that the incompleteness of asset markets causes inefficiency in almost every equilibrium. Yet unexplored is the ”size” of this inefficiency. The size of a Pareto improvement is the total willingness to pay for it, out of current consumption. Inefficiency is the maximum size of...

Child labor is often condemned as a form of exploitation. I explore how the notion of exploitation, as used in everyday language, can be made precise in economic models of child labor. Exploitation is defined relative to a specific social welfare function. I first show that under the standard...

This paper examines the connection between illegal migration, minimum wages and enforcement policy. We first explore the employers' decision regarding the employment of illegal migrants in the presence of an effective minimum wage. We show that the employers' decision depends on the wage gap...

Based on the current European discussion about immigration policy, this paper gives an overview of central economic consequences of immigration for a host country?s labor market. The most important theoretical arguments are presented and evaluated against the available empirical evidence. The...

Based on the ideas developed in the literature on the evaluation of active labor market policy, this paper provides a framework for the evaluation of key elements of immigration policy. To this end, the fundamental ingredients of evaluating policy interventions are explained and the specific...

International migration is maybe the single most effective way to alleviate global poverty. 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 individuals and governments who care about world...
