Immigration, distribution des revenus et bien-être social

This paper explores the consequences of immigration for aggregate income and income distribution. On the one hand, immigration generally increases the residents' aggregate income, on the other hand, it makes income distribution more unequal if immigrants bring little capital with them. These two effects can be analyzed jointly using a measure of social welfare. In general, the arrival of immigrants owning little capital lowers social welfare of residents and immigration of capital-rich persons increases it.
