We present a simple dynamic model based on on-the-job human capital accumulation affecting the dynamic of wage rates and labor earnings. We show how these dynamics are determined by the interplay between the supply and demand sides of the labor market. The model can generate and explain the...

This paper surveys intergenerational altruism in neoclassical growth models. It first examines Barro's approach to intergenerational altruism, whereby successive generations are linked by recursive altruistic preferences. Individuals have an altruistic concern only for their children, who in...

The Preston Curve - the increasing relation between income per capita and life expectancy - cannot be observed in countries where old-age dependency is widespread (that is, where long-term care (LTC) spending per capita is high). The absence of the Preston Curve in countries with high old-age...

This paper studies the optimal design of assisted reproductive technologies (ART) policies in an economy where individuals differ in their reproductive capacity (or fecundity) and in their wage. We find that the optimal ART policy varies with the postulated social welfare criterion....

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...

The European population is living longer but retiring earlier. More and more individuals are spending an increasing fraction of their life-time relying on retirement benefits. At the same time, social security programs face mounting financial difficulties. The purpose of this paper is to explain...

It is often argued that implicit taxation on continued activity of elderly workers is responsible for the widely observed trend towards early retirement. In a world of laissez-faire or of first-best efficiency, there would be no such implicit taxation. The point of this paper is that when...

The purpose of this paper is to survey the theoretical literature on wealth transfer taxation. The focus is normative: we are looking at the design of an optimal tax structure from the standpoint of both equity and efficiency. The gist of this survey is that the optimal design closely depends on...
