Capital-skill Complementarity and the Redistributive Effects of Social Security Reform

This paper analyses the general equilibrium implications of reforming pay-as-you-go pension systems in an economy with heterogeneous agents, human capital investment and capital–skill complementarity. It shows that increasing funding, by raising savings, delivers in the long run higher physical and human capital and therefore higher output, but also higher across-group wage and income inequality. It also shows that the general equilibrium effects induced by this reform affect groups' sizes in a way that the higher across-group inequality generated by more funding goes with a larger share of the population against redistribution.
