In this paper we develop an algorithm to numerically solve dynamic stochastic overlapping generations economies. In our model agents live for six periods and face idiosyncratic as well as aggregate uncertainty with respect to their labor and capital income. Insurance markets are absent and...

In this paper we identify conditions under which the introduction of a pay-as-you-go social security system is ex-ante Pareto-improving in a stochastic overlapping generations economy with capital accumulation and land. We argue that these conditions are consistent with many calibrations of the...

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...
