We examine the possibility of a Pareto-improving pay-as-you-go social security system, using an ex-ante welfare criterion. Our objective is to identify the conditions under which a suitably designed pay-as-you-go social security system is welfare improving, when markets are complete and...

The paper derives conditions for ex ante efficient intergenerational risk sharing in overlapping generations models. I show how the efficiency of a fiscal policy can be evaluated without distributional judgments, I derive efficiency conditions, and then examine specific models. For models with...

We analyze the sustainability of intergenerational transfers in politico-economic equilibrium. We argue that these transfers naturally arise in a Markov perfect equilibrium in the fundamental state variables. In contrast to earlier literature, our explanation does not resort to altruism,...
