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...

This paper investigates to what extent the 1998 reform of Sweden's public old-age pension system contributed to the increase in extensive margin labor supply among older workers seen in the country in recent decades. We use a large data set containing all males and females born in Sweden between...

The International Social Security (ISS) project compares the experiences of a dozen developed countries to study Social Security Programs and Retirement Around the World. The project was launched in the mid 1990s and was motivated by decades of decline in the labor force participation rate of...

Germany, like many other countries, has undergone a series of pension reforms since the 1980s which generally decreased benefit generosity and increased the retirement age due to demographic pressures. This paper investigates whether these reforms have increased income and wealth inequality...

We develop and estimate a life-cycle consumption savings model in which observed genetic variation is allowed to affect wealth accumulation through several distinct channels. We focus on genetic markers that predict educational attainment, aggregated into a predictive index called a polygenic...

In an earlier paper we analyzed a method of combining traditional tax financed pay-as-you-go Social Security benefits with annuities financed by Personal Retirement Accounts. We showed that such a combination could maintain the level of retirement income projected in current Social Security law...

This paper describes how three money's worth measures the benefit-to-tax ratio, the internal rate of return, and the net present value are calculated and used in analyses of social security reforms, including systems with privately managed individual accounts invested in equities. Declining...

Based on explicit present value calculations, the paper criticizes the view that the PAYGO system wastes economic resources. In present value terms, there is nothing to be gained from a transition to funded system even though the latter offers a permanently higher rate of return. The sum of the...

This paper uses a lifetime framework to address questions about the progressivity of social security and proposed reforms. We use a large sample of diverse individuals from the PSID to calculate lifetime income, to classify individuals into income quintiles, and then to calculate the present...
