This paper establishes three-sector general equilibrium models and separately investigates how sector-biased corruption influences the wage rates of skilled and unskilled workers, the wage inequality, and the amount of unskilled rural–urban migrants in developing countries. Corrupt activities are introduced in our theoretical models as transaction costs. We find that the reductions in different sector-biased corrupt behaviors exert different impacts through various economic mechanisms. In addition, the change in urban unskilled unemployment due to the decrease in the degree of sector-biased corruption is also taken into account.
