Intergenerational Risk Sharing, Pensions and Endogenous Labor Supply in General Equilibrium
CESifo, Munich, 2008
CESifo Working Paper No. 2185
In the context of a two-tier pension system, with a pay-as-you-go first tier and a fully funded second tier, we demonstrate that a system with a defined wage-indexed second tier performs strictly better than one with a defined contribution or defined real benefit second tier. The former completely separates systematic redistribution (confined to the first tier) from intergenerational risk sharing (the role of the second tier). This way labor supply is undistorted.
