This paper examines how immigrants' migration duration and saving decisions in the host country respond to the purchasing power parity (ppp) and the wage ratio between the host and source countries. It is shown that in theory immigrants may stay longer in the host country as a result of an...

Immigration is one of the most hotly debated policy issues in the United States today. Despite marked divergence of opinions within political parties, several important immigration reforms were introduced in the post 1965 era.

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...

This paper studies the impact of U.S. immigration barriers on global knowledge production. We present four key findings. First, among Nobel Prize winners and Fields Medalists, migrants to the U.S. play a central role in the global knowledge network— representing 20-33% of the frontier...

We estimate whether migration can be an equilibrating force in the labour market by comparing pre- and post-crisis migration movements at the regional level in both Europe and the United States, and their association with asymmetric labour market shocks. Based on fixed-effects regressions using...

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...

We document the transmission of social distancing practices from the United States to Mexico along migrant networks during the early 2020 Covid-19 pandemic. Using data on pre-existing migrant connections between Mexican and U.S. locations and mobile-phone tracking data revealing social...

We estimate differences in innovation behavior between foreign versus U.S.-born entrepreneurs in high-tech industries. Our data come from the Annual Survey of Entrepreneurs, a random sample of firms with detailed information on owner characteristics and innovation activities. We find uniformly...

The question of whether migration can be an equilibrating force in the labour market is an important criterion for an optimal currency area. It is of particular interest currently in the context of high and rising levels of labour market disparities, in particular within the Eurozone where there...

How does saving behavior of immigrants respond to changes in purchasing power parity between the source and host countries? We examine this question by building a theoretical model of joint return-migration and saving decisions of temporary migrants and then test its implications by using data...
