This paper studies why illegal immigration is widespread. We develop a political agency model in which a politician decides on an immigration target and its enforcement, facing uncertainty on the supply of migrants. Illegal immigration can arise for two reasons: the policy maker may be unable to...

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...

A number of states have adopted laws that require employers to use the federal government's E-Verify program to check workers' eligibility to work legally in the United States. Using data from the Current Population Survey, this study examines whether such laws affect labor market outcomes among...

Using the 2005-2014 waves of the American Community Survey - a period characterized by the rapid expansion of interior immigration enforcement initiatives across the United States, we evaluate the impact of a tougher policy environment on undocumented immigrants' fertility. We find that a one...

The 1986 US Immigration Reform and Control Act (IRCA) was directed at tackling the problem of growing unauthorized migration through legalization of unauthorized immigrants, increasing border security and sanctioning employers who hired unauthorized immigrants. Our paper investigates how the...

Two issues have taken center stage in the recent debates about U.S. immigration policy: one, illegal immigration and more generally the entrance of poorly educated individuals into the U.S. economy and two, whether the U.S. should continue its family-based admissions system or move towards a...

The recent impetus of tougher immigration-related measures passed at the state-level raises concerns about the impact of such measures on the migration experience, trajectory and future plans of unauthorized immigrants. In a recent and unique survey of Mexican unauthorized immigrants interviewed...

This paper investigates the effect of U.S. border enforcement on the net flow of Mexican undocumented migration. It shows how this effect is theoretically ambiguous, given that increases in border controls deter prospective migrants from crossing the border illegally, but lengthen the duration...

We explore whether fear of apprehension affects immigrants' labor market engagement by examining how ICE removals due to immigration violations and increased awareness of immigration raids impact their labor market outcomes. We find that ICE deportations are associated with reductions in the...

This paper establishes a new fact about immigration policies: legalization has long-term effects on formal employment of undocumented immigrants and their assimilation. We exploit the broad amnesty enacted in Italy in 2002 together with rich survey data collected in 2011 on a representative...
