Our hypothesis is that immigrants, who often do not speak the language and do not the culture and norms of the host country, are concentrated in more manual-routine tasks (especially among less educated groups). The inflow of immigrants thus increases the supply of manual skills relative to the supply of abstract skills with two effects:
● Due to the complementarity between these types of skills, the increase in the supply of manual tasks boosts relative compensation for complex skills, them better paid.
● Exploiting their comparative advantage, natives move to occupations requiring a relatively higher level of these skills.
This positive reallocation and the complementarity of tasks can explain the lack of negative employment effects as well as the potential positive wage effects of immigration on native workers.
So here"s how it all shakes out. Low-skilled immigration reduces economic inequality when we set aside nationalist assumptions and focus on people instead of populations. Even if we cling to ytical and moral nationalism, low-skilled immigration doesn"t happen to increase measured inequality. On the contrary, complementaries between the skills of migrant and native workers can leave natives better off than they would have been with less immigration.
