We provide the first evidence on the causal effect of border enforcement on the full spatial distribution of Mexican immigrants to the United States. We address the endogeneity of border enforcement with an instrumental variables strategy based on administrative delays in budgetary allocations...

Over the past decade, a number of federal and state policies intended to stem the flow of illegal immigration have been implemented. In this paper, we focus on two initiatives: (a) Operation Streamline, as an example of increased border enforcement by the federal government, and (b) state-level...

Canonical models of migration feature border enforcement as a strategy to contain undocumented immigration by effectively exacting a mobility cost. This paper revisits the role of border enforcement policy in a task-based model of the labor market where employers simultaneously hire circular...

Fatalities from illegal immigration from Africa is an important issue, representing a major challenge for both major migrant sending and receiving countries. Nonetheless, almost nothing is known about how the illegal migration intentions of potential migrants are formed. This paper aims to...

Programs aimed at reducing the presence of unauthorised immigrants are often at the core of the migration policy debate in host countries. In recent years, a growing body of empirical literature has attempted to understand the effect of lacking legal status on immigrants' outcomes and behaviour....

Do general amnesty programs lead to reductions in the crime rate among immigrants? We answer this question by exploiting both cross-sectional and time variation in the number of immigrants legalized generated by the enactment of repeated amnesty programs between 1990 and 2005 in Italy. We...

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...

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...

The United States currently provides Temporary Protected Status (TPS) to more than 300,000 immigrants from selected countries. TPS is typically granted if dangerous conditions prevail in the home country due to armed conflict or a natural disaster. Individuals with TPS cannot be deported and are...

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...
