Distributional change is a complex phenomenon and there are many forces at work. This paper focuses on those forces that are more directly related to supply and demand trends in labor markets. On the supply side it considers: demographic shifts, improvement in education achievements and policies related to labor supply (such as increasing access to education, enabling inter-sectoral mobility, etc.); and, on the demand side: technological change, sectoral pattern of growth, and trade (globalization). The intergenerational improvement in education will increase the supply of skilled workers. By the time these young cohorts reach the labor market, there would be important consequences on skill wage premia, sector mobility and income distribution. For understanding these outcomes in the long run a general equilibrium setup is much needed.
