The economie impact of immigration for the host countries
In this paper, we will investigate the economic consequences of immigration for the host countries. Recently, the debate has been centered on the role of immigration in the process of aging. A priori, the immigration of workers is likely to affect the economic situation of the host country in multiple ways, both positive and negative. Most studies focused on the labor market reveal a weak net gain of immigration whose distribution depends on the skill structure of immigrants and domestic labor force. Empirical studies show that past immigration had only a weak impact on native wages and unemployment rate. The net effects on welfare benefits are not clear and are related to the composition of migrant flows. Studies analyzing the relations between the labor force migrations and the dynamics of growth of the concerned areas put forward different mechanisms according to whether one uses exogenous or endogenous growth models. However, whatever the theoretical framework considered, the immigrants’ skills will be the determinant variable.
