Social Security faces a major financing shortfall. One policy option for addressing this shortfall would be to raise the earliest age at which individuals can claim their retirement benefits. A welfare analysis of such a policy change depends critically on how it affects living standards. This...

We study associations among women's current marital status, past marital history, and later-life labor force participation. We first document these relationships using data from the 1986 to 2008 waves of the Survey of Income and Program Participation (SIPP). We then exploit variation in laws...

We construct a database of public pension policy changes with motivation and implementation information for ten OECD countries. Structural pension reforms, motivated by long-run sustainability concerns, often come with prolonged phase-in periods. In response to pension retrenchments implemented...

We estimate the impact of public pension systems on labor supply far from the normal retirement age by exploiting Poland's switch from a Defined Benefit to a Notional Defined Contribution scheme for men born after 1948. Using the universe of taxpayers and this sharp cohort-based discontinuity in...

In earlier literature, the suggested Pareto improvements in pay-as-you-go (PAYG) systems have relied on the presence of externalities or the possibility of intragenerational redistribution. We show that neither assumption is necessary in an economy with intergenerational trade in a fixed factor...

This paper discusses the efficiency of a pay-as-you-go pension reform by introducing a child benefit in an endogenous fertility setting. In the model of a small open economy, higher fertility is associated with a reduction of lifetime labor supply. The optimum share of fertility-related pensions...

In this paper we model an OLG-economy where labour supply is endogenously determined and where we assume that there are two pension systems, namely, a pay-as-you-go system and a funded system. The main question is whether there is an equilibrium involving an old-age pensions system, partly...

This paper analyses the general equilibrium implications of reforming pay-as-you-go pension system in an economy with heterogeneous agents, human capital investment and capital-skill complementarity. It shows that increasing funding delivers in the long run higher physical and human capital and...

The aging of the population shakes the public finance of pay-as-you-go social security systems. We develop a political-economy framework in which this demographic change leads to the downsizing of the social security system, and, as a consequence, to the emergence of supplemental individual...
