Public infrastructure provision and skilled–unskilled wage inequality in developing countries

Abstract

In this paper, we develop several static three-sector general equilibrium models with diverse labor market structures to investigate the effects of government provision of public infrastructure on the skilled–unskilled wage inequality in developing countries. The basic full employment model shows that the production sectors' relative dependence on the public infrastructure provision plays a crucial role in determining the skilled–unskilled wage inequality. Different relative dependences on public infrastructure may even result in opposite changes in the skilled–unskilled wage inequality. The above results are robust even when we extend the basic full employment model to three fundamentally different cases.
