This paper extends the Diamond overlapping-generations model with pay-as-you-go social security by allowing for variable retirement age and for distortionary taxation of earnings and interest income. The tax rates are shown to depend on whether or not debt policy is available, and on the...

This paper studies the design of retirement and disability policies when individuals differ in both productivity and health. The second-best solution implies (downward) distortions in the (per-period) labor supply and in the choice of retirement age for some individuals, and lesser...

One of the greatest success stories in our societies is that people are living longer, life expectancy at birth being now above 80 years. Whereas the lengthening of life opens huge opportunities for individuals if extra years are spent in prosperity and good health, it is however often regarded...

Our societies are witnessing a steady increase in longevity. This demographic evolution is accompanied by some convergence across countries, whereas substantial longevity inequalities persist within nations. The goal of this paper is to survey some crucial implications of changing longevity on...

Although the optimal public policy under an endogenous number of children has been widely studied, the optimal public intervention under an endogenous timing of births has remained largely unexplored. This paper examines the optimal family policy when the timing of births is chosen by...

Should special pension provisions be offered to workers in harsh occupations? We address this question in an optimal tax setting where individuals differ in longevity and occupation. Longevity is private information but workers in harsh occupations have on average shorter lifes than workers in...

We study the optimal design of a social security system when individuals differ in health status and occupation. The health status is private information but is imperfectly correlated with occupation: individuals in harsh occupations have a higher probability of being in poor health. We explore...

Demographic realities will soon force developed countries to find ways to pay for longer retirements for more people. In Pension Strategies in Europe and the United States, leading economists analyze topical issues in pension policy, with a focus on raising the retirement age, increasing...
