Immigration and Native Wages
An S-curve Relationship
Abstract
This paper presents a tractable theoretical model in which native wages and the number of migrants exhibit an s-curve relationship. In this model, with a very small or with a very large number of migrants, more migrants depress native wages. However, with an intermediate number of migrants, native wages are increasing in the number of migrants. Whether natives can benefit from migrants, and native wages can rise above its pre-migration level or not depends on the productivity difference between natives and migrants, and the size of the sector in which migrants have a comparative advantage.
