We solve the dynamic occupational choice problem of a finitelylived, borrowing constrained household which faces exogenously given stochastic wages and business returns. Entrepreneurship means investing personal wealth into a risky asset and neither receiving wage income nor paying social...

Public social security systems may provide diversification of risks to individuals’ life-time income. Capturing that a pay-as-you-go program (paygo) may be considered as a “quasiasset”, we study the optimal size of the social security program as well as the optimal split between a funded...

Pay-as-you-go (PAYG) pension schemes can contribute to better intergenerational risk-sharing and diversification. However, different variants of PAYG schemes entail different properties in these respects. In a stochastic 2-OLG model we compare PAYG schemes with fixed contribution rates and such...

In this paper we show how pay-as-you-go pension schemes impact on the individual.s optimal investment portfolio. Introducing a pay-as-you-go pension scheme implies that human wealth of young generations is transferred to retired generations. As a consequence, individuals will in general invest...

This article outlines the recommendations of the UK Pensions Commission, and the data and analysis on which they were based, including projections of demographic change, trends in private pension saving, and evolution of the state pension system. The Commission concluded that without reform,...

This paper presents an estimation of the revenues of the Uruguayan pension system, its financial situation and itsimpact on the Central Government finances between 1896 and 2008. The revenues and expenditures of the Social Security Bank (wich covers the retirement funds for workers of the Civil...

We consider an overlapping generations model with public education and social security financed by labor income taxation, in which the overall size of these policies is determined in a repeated majority voting game. We investigate the interaction between these policies and economic development...

Pension systems have wide-ranging and important effects. They influence the living standards of older people and hence the welfare of both older people and their children. They can also affect national economic performance through potential effects on the labor supply and saving. The design of...

This paper studies the effect of population aging on economic performance in an overlapping-generations model with international migration. Fertility is endogenized so that immigrants and natives can have different fertility rates. Fertility is an important determinant to the tax burden of...

This paper analyzes the dynamic politico-economic equilibrium of a model where repeated voting on social security and the evolution of household characteristics in general equilibrium are mutually affected over time. In particular, we incorporate within-cohort heterogeneity in a two-period...
