Feldstein [1985] posed the questions of what would be the optimal level of retirement benefit, and what would be the optimal mix between the pay-as-you-go system and the funded pension system under the assumption of an exogenous interest rate. We reconsider the problem with the addition of a...

Feldstein [1985] posed the questions of what would be the optimal level of retirement benefit, and what would be the optimal mix between the pay-as-you-go system and the funded pension system under the assumption of an exogenous interest rate. We reconsider the problem with the addition of a...

This study uses German social security records to provide novel evidence about the heterogeneity in life expectancy by lifetime earnings and, additionally, documents the distributional implications of this earnings-related heterogeneity. We find a strong association between lifetime earnings and...

This paper examines the impacts of social pension provision among people of different ages. Utilizing the county-by-county rollout of the New Rural Pension Scheme in rural China, we find that, among the age-eligible people, the scheme provision leads to higher household income (18 percent) and...

Many nations are seeking to reform their welfare states so that costs to the government can be reduced and the quality of outcomes improved. As a potential way to achieve these aims, there has been a surge of interest in the Singaporean model which features compulsory savings accounts and...

Many countries consider rising fertility through pro-family policies as a solution to the fiscal pressure stemming from longevity. However, an increased number of births implies immediate private costs and only delayed public benefits of younger and larger population. We propose using an...

We develop an OLG model with realistic assumptions about longevity to analyze the welfare effects of raising the retirement age. We look at a scenario where an economy has a pay-as-you-go defined benefit scheme and compare it to a scenario with defined contribution schemes (funded or notional)....

We analyze the consumption and wealth inequality in an OLG model with mandatory pension systems. Our framework features within cohort heterogeneity of endowments and heterogeneity of preferences. We allow for population aging and gradual decline in TFP growth. We show four main results. First,...
