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...

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...

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...

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,...

Diasporas are global communities of migrants who retain a sense of connection with their homeland. The concept is ancient but has only recently become an important area of research in economics. Due to their unique transnational characteristics, diasporas can have significant influence over...

This paper examines ethnicity among highly skilled immigrants to the United States. The paper focuses on five classic components of ethnicity - country of birth, race, skin color, language, and religion - among persons admitted to legal permanent residence in the United States in 2003 in the...

This paper investigates the effect of the US Illegal Immigrant Reform and Immigrant Responsibility Act of 1996 (IIRIRA) on the remitting patterns of Mexican immigrants. Using data from the Mexican Migration Project (MMP128), we find that a significant effect on remittance flows from illegal...

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...

This is a draft chapter for the Handbook on Economics of International Migration (Eds. B. R. Chiswick and P. W. Miller) and deals with the political incorporation of immigrants in host societies. Political incorporation is discussed with regard to the regulation of legal status, rights,...

Economic theory suggests that selective immigration policies based on observable characteristics will affect unobservable migrant quality. Little empirical evidence exists on this hypothesis. We quantify traditionally unobservable components of migrant quality in Australia, a high-migrant share...
