This paper studies an overlapping generations model with stochastic production and incomplete markets to assess whether the introduction of an unfunded social security system leads to a Pareto improvement. When returns to capital and wages are imperfectly correlated a system that endows retired...

In this paper we quantitatively characterize the optimal capital and labor income tax in an overlapping generations model with idiosyncratic, uninsurable income shocks, where households also differ permanently with respect to their ability to generate income. The welfare criterion we employ is...

This paper analyzes intergenerational redistribution in a 2-period overlapping- generations model that allows for heterogeneous labor productivities within the working generation. In each period, the government decides about redistributive transfers to maximize the aggregate utility of the...

In this paper redistribution policy is analyzed in a 2-period overlapping generations model with heterogeneous individuals and asymmetric information between the government and the private sector. Individuals of the same generation differ with respect to their labor productivity. In each period,...

An overlapping generations model is set up in this paper to analyze social security policy in a representative democracy with asymmetric information. The model considers not only redistribution between generations but also redistribution within generations according to individual labor incomes....
