The Impact of International Migration on the Economy with the Assumption of Labor Heterogeneity

T his study investigated the effect of international labor migration on Iran’s economy using a neo-classical growth model with the assumption of labor heterogeneity within the framework of dynamic stochastic general equilibrium model. After solving the model, the obtained equations were linearized and different values were assigned to the parameters according to Iran’s economy information. The results indicated that emigration of skilled labor force reduced production, investment, and per capita consumption, increased skilled individuals’ wages, and decreases wages for unskilled individuals; however, immigration enhanced labor force and population and reduced production, investment and per capita consumption. On the other hand, the labor force’s wages also declined with an increase in unskilled labor force. Furthermore, a variation in the degree of substitution between unskilled labor and capital only changed the impact of the immigration momentum and had no impact on the type of relationship. If emigration consists of a combination of skilled and unskilled labor force, its effectiveness only changes.
