The present paper simulates the privatization of social security in an economy populated by overlapping generations of individuals that have time-consistent or time-inconsistent preferences, face mortality and individual income risk as well as borrowing constraints. We compute the transition...

Social security programs generally seek to provide insurance and to reduce poverty and inequality. Providing insurance requires little redistribution. But reducing inequality and alleviating poverty do require redistribution. To reduce inequality, programs must redistribute income, but...

We compare a social security system where people can retire at an age of their own choice with one in which there is a legal retirement age elected through a majority voting process. We show that individuals prefer a legal retirement age higher than the one they would choose in the flexible...

This paper investigates the role of recent pension reforms for the development of the social security system and economic growth in Austria. We use a computable general equilibrium model that is built up of overlapping generations that differ by their household structure, longevity, educational...

We investigate the responsiveness of individual retirement decisions to changes in financial incentives. A reform increased women's normal retirement age (NRA) in two steps from age 62 to age 63 first and then to age 64. At the same time retirement at the previous NRA became possible at a...

This paper constructs a structural retirement model with hyperbolic preferences and uses it to estimate the effect of several potential Social Security policy changes. Estimated effects of policies are compared using two models, one with hyperbolic preferences and one with standard exponential...

In this paper, I characterize the optimal redistribution policy in a simple life-cycle framework with both an intensive and an extensive margin of labor supply. The extensive margin corresponds to the choice of a retirement age. The optimal allocation cannot be implemented in a decentralized...

Brazil’s public pension expenditure is about 9 per cent of GDP, above the OECD average. Given that OECD countries are generally not only wealthier, but also significantly older, Brazil’s pension expenditures are clearly excessive, draining resources away from other areas, such as much needed...

This paper examines the impact of old-age pension systems and other social transfer programmes on the retirement decision of older males in OECD countries. For each of the 55-59, 60-64 and 65+ age groups, a new panel dataset (22 OECD countries over 1969-1999 or shorter periods in some cases) of...

This paper quantifies the effects of social security on capital accumulation and wealth distribution in a life-cycle framework with altruistic individuals. The main findings of this paper are that the current U.S. social security system has a significant impact on capital accumulation and wealth...
