We set up a lifecycle model of a retired scholar who chooses optimally the time devoted to different activities including physical activity, continued work and social engagement. While time spent in physical activity increases life expectancy, continued scientific publications increases the...

From 1850 to 2000, in Western European countries life expectancy rose from 30–40 to 80 years and the average number of children per woman fell from 4 to 5 children to slightly more than one. To gauge the economic consequences of these demographic trends, we implement an overlapping generations...

In this paper we investigate the impact of a reduction in the pension replacement rate on the schooling choice and on inequality. We develop an overlapping generations model in which individuals differ by their life expectancy and in the cost of attending schooling. Individuals optimally choose...

As the heterogeneity in life expectancy by socioeconomic status increases, pension systems become more regressive implying wealth transfers from short to long lived individuals. Various pension reforms aim to reduce these inequalities that are caused by ex-ante differences in life expectancy....
