Une étude économique, à paraitre dans le Economic Journal et signalée par Tyler Cowen relève les effets positifs de l’immigration, en Europe, sur les salaires des moins éduqués. A l’inverse, l’émigration a sur eux un effet plus négatif.
In this paper, we quantify the labor market effects of migration flows in OECD countries during the 1990′s based on a new global database on the bilateral stock of migrants, by education level. We simulate various outcomes using an aggregate model of labor markets, parameterized by a range of estimates from the literature. We find that immigration had a positive effect on the wages of less educated natives and it increased or left unchanged the average native wages. Emigration, instead, had a negative effect on the wages of less educated native workers and increased inequality within countries.
En prime, le commentaire de Tyler Cowen :
Yes, I am familiar with how these models and estimates work, and yes you can argue back to a “we really can’t tell” point of view, if you are so inclined. But you cannot by any stretch of the imagination argue to some of the negative economic claims about immigration that you will find in the comments section of this blog and elsewhere.
