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 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...

Illegal migrants supply a valuable productive input: effort. But their status as illegals means that these migrants face a strictly positive probability of expulsion. A return to their country of origin entails reduced earnings when the wage at origin is lower than the wage at destination. This...

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...

Border enforcement of immigration laws raises the costs of illegal immigration, while interior enforcement also lowers its benefits. Used together, border and interior enforcement therefore reduce the net benefits of illegal immigration and should lower the probability that an individual will...

Border enforcement of immigration laws attempts to raise the costs of illegal immigration, while interior enforcement also lowers the benefits. Border and interior enforcement therefore reduce the net benefits of illegal immigration and should lower the probability that an individual will decide...

Illegal immigration affects not only EU member states at the Mediterranean Sea but also more Northern states due to open internal borders and onward migration. Northern member states may free-ride on border countries’ enforcement efforts, leading to a sub-optimal level of border control. While...
