In this paper, a social-welfare maximizing public-pension policy is modeled within the framework of the well-known two-overlapping-generations, general-equilibrium model with rational expectations. The model is used to analyze the effects of aging on the evolution of public-pension schemes. Analytical results are derived for the long run as well as for the short run by the method of comparative statics and comparative dynamics respectively. This shows that the short-run consequences of aging depend crucially on the existing size of the pay-as-you-go-scheme. Copyright 1997 by Royal Economic Society.
