Bulgaria is undergoing a profound socio-economic transformation brought about by extraordinary demographic change. Between 1950 and 1990, Bulgaria’s population grew from 7.3 million to 8.8 million and then declined to 7.5 million by 2010. Low birth rates and high mortality rates combined with...

This paper analyzes and compares the macroeconomic performance of defined-benefit and defined-contribution pay-as-you-go pension systems when population ages. When the fertility rate decreases or longevity rises, it is shown that a shift from defined benefit (defined total benefit or defined...

This paper studies the design of an optimal non linear inheritance taxation when individuals differ in wage as well as in their risks of both mortality and old-age dependance. We assume that the government cannot distinguish between bequests motives, that is whether bequests result from...

Our societies are witnessing a steady increase in longevity. This demographic evolution is accompanied by some convergence across countries, but at the same time substantial longevity inequalities persist within nations across income classes. This Element aims to survey some crucial implications...

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...

Leading economists analyze topical issues in pension policy, including structural reform of pay-as-you-go systems, the political sustainability of pension reforms, and the need for private, funded systems.

We consider a two-period overlapping generations model in which individual voters differ by age and by productivity. In such a setting, a redistributive Pay-As-You-Go system is politically sustainable, even when the interest rate is larger than the rate of population growth. The workers with...
