We build a general equilibrium model in which both illegal immigration and the size of the informal sector are endogenously determined. In this framework, we show that indirect policy measures such as tax reduction and detection of informal activities can be used as substitutes for border...

Restricting immigration to young and skilled immigrants using a point system, as in Canada, Australia, and New Zealand, succeeds in selecting economically desirable immigrants and provides orderly management of population growth. But the point system cannot fix short-term skilled labor shortages...

In this paper I share my thoughts on immigration policy. As a social scientist it is appropriate to assess the consequences, the costs and benefits, of alternative immigration policies. The policies that a country adopts regarding immigration, however, should be the outcome of a political...

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...

We study the interaction between the optimal immigration policy of a host country and education policy of a source country in a model of international migration of skilled workers. Acquisition of human capital is driven by the academic and career opportunities at home and abroad. Greater...

A growing number of OECD countries are leaning toward adopting quality-selective immigration policies. The underlying assumption behind such policies is that more skill-selection should raise immigrants' average quality (or education level). This view tends to neglect two important dynamic...

Did recent technological change, in the form of automation, affect immigration policy in the United States? I argue that as automation shifted employment from routine to manual occupations at the bottom end of the skill distribution, it increased competition between natives and immigrants,...

We study a reform that granted European cross-border workers free access to the Swiss labor market and had a stronger effect on regions close to the border. The greater availability of cross-border workers increased foreign employment substantially. Although many cross-border workers were highly...

In 2010, an amendment to the Dominican constitution weakened the concept of jus soli citizenship by denying Dominican nationality to individuals born on Dominican soil to irregular immigrants. A few years later, in 2013, the Dominican High Court denationalized large numbers of individuals by...

What is the effect of opening the labor market to foreign workers on the success of firms? We address this question by analyzing how firms in Switzerland were affected by the introduction of the free movement of persons with the European Union (EU) countries. This immigration reform granted all...
