IZA DP No. 13755: An Introduction to the Economics of Immigration in OECD Countries

Forthcoming in: Canadian Journal of Economics

The share of the foreign-born in OECD countries is increasing, and this article summarizes economics research on the effects of immigration in those nations. Four broad topics are addressed: labor market issues, fiscal questions, the political economy of immigration, and productivity/international trade. Extreme concerns about deleterious labour market and fiscal impacts following from new immigrants are not found to be warranted. However, it is also clear that government policies and practices regarding the selection and integration of new migrants affect labour market, fiscal and social/cultural outcomes. Policies that are well informed, well crafted, and well executed beneficially improve population welfare.
