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 order to stimulate labor market participation and improve the financial viability of the social security systems, many recent reform proposals in various OECD economies suggest to scale down the non-actuarial parts of the pension systems. These reforms have a flavour of increased efficiency...

The paper shows the effect of demographic change on per capita burden of financing a PAYG social security system in the standard OLG model with frictional labor markets. Rising longevity and decreasing fertility both induce a rise in the employment level via increased capital accumulation and...

Japan is in the midst of a demographic transition that is both rapid and large by international standards. As recently as 1990, Japan had the youngest population among the Group of 6 large, developed countries. However, the combined effects of aging of the baby boomer generation and low...

This paper analyzes the aggregate effects of a revenue neutral fiscal-cumsocial policy reform in a typical developing country that consists of two main changes: (1) the implementation of universal social insurance to replace the current dual social protection system (i.e., a reconfiguration of...

This paper proposes a method for the welfare analysis of pay-as-you-go social security systems. We derive a formula for the welfare consequences of a permanent marginal change in the payroll tax rate that is valid under weak assumptions about the deep structure of the economy. Our approach...

We explore voluntary participation in pension arrangements. Individuals only participate when participation is more attractive than autarky. The bene??it of participation is that risks can be shared with future generations. We apply our analysis to a pay-as-you-go system, a funded system without...

This paper introduces a methodological innovation into Generational Accounting. By incorporating cyclically-adjusted balances into the forward-looking budget projections underlying the concept we isolate pure policy effects, which render comparisons of the fiscal sustainability indicators...

This paper investigates fiscal sustainability in an overlapping generations economy with endogenous growth coming from human capital formation through educational spending. We assess how budgetary imbalances affect economic dynamics and the outlook for economic growth, thereby providing a...

This chapter defines a universal public pension scheme (UPPS) as a government-mandated lifecycle longevity insurance scheme that transfers individual consumption from the working years to the retirement phase of the lifecycle. It discusses the differences in four UPPS designs defined with regard...
