Wpływ migracji na dobrobyt w krajach OECD
The Impact of Migration on Welfare in the OECD Countries

Summary/Abstract: The paper presents the quantification of the consequences of migration for the welfare of people living in the OECD countries. The results are obtained by simulating migration shocks using a general equilibrium model with endogenous wages and prices. Assuming imperfect substitution between low and high-skilled workers, as well as natives and foreigners, we get that actual immigration brings an increase in the real wages of low-skilled people and causes a decrease in the remuneration of high-skilled workers. Emigration has an opposite implication. The overall welfare impact of migration is decomposed into three sub-effects: the market size, nominal wage and productivity effects. The results of this paper provide quantitative arguments for the discussion about the costs and benefits of global migration.
