We develop a general model of legal and illegal immigration to understand the basic tradeoffs faced by a government in the decision to implement an immigration amnesty in the presence of a selective immigration policy. We show that two channels play an important role: an amnesty is more likely...

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...

In the first part of this paper, we present a stylised model of the labour market impact of immigration. We then discuss mechanisms through which an economy can adjust to immigration: changes in factor prices, output mix and production technology. In the second part, we explain the problems of...

This paper analyses the effect immigration has on wages of native workers. Unlike most previous work, we estimate wage effects along the distribution of wages. We derive a flexible empirical strategy that does not rely on pre-allocating immigrants to particular skill groups. In our empirical...

This paper analyses the effect of emigration from Poland around the time of EU accession on the Polish labour market. We develop a simple model that guides our empirical specification and provides a clear interpretation for our estimates. Focussing on the 1998–2007 period for Poland, we...

In this paper, we investigate the fiscal impact of immigration on the UK economy, with a focus on the period since 1995. We provide estimates for the overall immigrant population for the period between 1995 and 2012, and for more recent immigrants who arrived since 2000, distinguishing between...

This paper estimates the causal effect of the prospect of legal status on the employment outcomes of undocumented immigrants. Our identification strategy exploits a natural experiment provided by the 2002 amnesty program in Italy that introduced an exogenous discontinuity in eligibility based on...

This paper starts with a brief historical overview of immigration in Europe. We then provide a comprehensive analysis of the skill structures of immigrants and their labor market integration in the different European countries, their position in the wage distribution, and the situation of their...

This paper reviews the labour market performance and educational attainment of ethnic minorities and second generation immigrants in the UK over the last three decades. We first describe the size and composition of the minority population and its regional distribution over time, and investigate...

This paper assesses the fiscal consequences of migration to the UK from the Central and Eastern European countries that joined the EU in May 2004 (A8 countries). We show that A8 immigrants who arrived after EU enlargement in 2004, and who have at least one year of residence - and are therefore...
