Longevity and Lifetime Labor Supply: Evidence and Implications
检验了寿命延长会提高终身劳动供给这一条件，发现1840-1970年间出生的美国男性及1890-1970年间出生的美国人口均不满足该条件，西欧也有类似模式，并讨论了这对长期增长根本原因的启示。
Conventional wisdom suggests that increased life expectancy had a key role in causing a rise in investment in human capital. I incorporate the retirement decision into a version of Ben-Porath's (1967) model and find that a necessary condition for this causal relationship to hold is that increased life expectancy will also increase lifetime labor supply. I then show that this condition does not hold for American men born between 1840 and 1970 and for the American population born between 1890 and 1970. The data suggest similar patterns in Western Europe. I end by discussing the implications of my findings for the debate on the fundamental causes of long-run growth.
