Intergenerational risk sharing, pensions and endogenous labour supply in general equilibrium

We show that a two-tier pension system, with a pay-as-you-go first tier and a fully funded, defined wage-indexed second tier, can provide for optimal intergenerational risk-sharing without distorting the labour supply, thereby achieving the first best. Other arrangements with a fully-funded second tier fail to achieve the first best.

Netspar, Network for Studies on Pensions, Aging and Retirement, is a thinktank and knowledge network. Netspar is dedicated to promoting a wider understanding of the economic and social implications of pensions, aging and retirement in the Netherlands and Europe.
