Life expectancy and income: The Ben-Porath mechanism revisited

In this paper we show that it may be optimal for individuals to educate themselves more and decrease future labor supply (choose earlier retirement) when life expectancy increases. This result reconciles the findings of Hazan [Hazan, M., 2009. Longevity and Lifetime Labor Supply: Evidence and Implications. Econometrica 77, 1829.1863] with theory. Further, the paper contributes to a better understanding of the conflicting empirical findings on the causal effect on income per capita from increased life expectancy.
