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...

Legal and illegal markets often coexist. In theory, marginal legalization can either substitute for the remaining parallel market, or complement it via scale effects. I study migrants crossing without prior authorization at the US southwest border, where large-scale unlawful crossing coexists...

This paper examines the effects of reducing the supply of low-skilled immigrant workers on the labor market outcomes of domestic workers. We use temporal and geographic variation in the introduction of Secure Communities (SC), a county-based immigration enforcement policy, combined with data...

Canada's immigration system is currently undergoing significant change driven by several goals that include (1) a desire to improve the economic outcomes of entering immigrants; (2) an attempt to better respond to short-term regional labor market shortages often associated with commodity booms,...

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 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...

From 1860 to 1913 the six colonies that became states of Australia strove to attract migrants from the UK with a variety of assisted passages. The colonies/states shared a common culture and sought migrants from a common source, the UK, but set policy independently of each other. This experience...

Switzerland has experienced a substantial influx of immigrants over the last 50 years after World War II, which has led Switzerland to have among the highest share of foreigners in population among all OECD countries. This paper analyses the migration experience of Switzerland. The analysis...

In this paper we analyze the endogenous determination of migration quota viewing it as an outcome of a two-stage political struggle between two interest groups: those in favor and those against the proposed migration quota. We first compare the proposed policies of the two interest groups under...

We review developments in research on within-country migration, focusing on internal migration in the U.S. We begin by describing approaches to modelling individuals' migration decisions and equilibrium outcomes across local areas. Next, we summarize evidence regarding the impact of migration on...
