How immigration benefits natives despite labour market imperfections and income redistribution, by Michele Battisti, Gabriel Felbermayr, Giovanni Peri, and Panu Poutvaara, Vox EU: Immigration continues to be a hotly debated topic in most OECD countries. Economic models emphasising the benefits of immigration for natives have typically neglected unemployment and redistribution – precisely the things voters are most concerned about. This column analyses the effects of immigration in a world with labour market rigidities and income redistribution. In two-thirds of the 20 countries analysed, both high-skilled and low-skilled natives would benefit from a small increase in immigration from current levels. The average welfare gains from immigration are 1.25% and 1.00% for high- and low-skilled natives, respectively.
And the conclusion:
Our analysis shows that immigration into imperfectly competitive labour markets need not be worsening labour market outcomes for natives. Instead, it can improve the job creation incentives of firms. Thus, measures that aim at eliminating the immigrant–native wage gap may hurt natives. This positive effect is threatened if immigrants are too often unemployed or if too many of them are unskilled. Policies reducing the rate of job loss for immigrants would therefore help natives. Finally, in contrast to widespread belief, immigrants do not seem to hurt low-skilled natives, even in the more realistic framework developed here. This is because immigration is often balanced between more and less educated, because its job-creation effect can help, and because redistribution towards immigrants is not as large as often suggested in the debate.
