Recent papers have suggested that the Industrial Revolution in Europe ultimately derives from the labor scarce economy of northwest Europe, which some trace back to the Black Death [Voigtländer and Voth (2013a) and Allen (2011)]. This paper examines the effects of the Black Death in England. Specifically, did it merely change relative factor prices, or did it lead to lasting gains in the efficiency of the economy after 1348? Extensive wage and price data from England 1210–1800 suggest that the population losses of the Black Death were associated with a surprising increase in economic efficiency, despite the decline in the scale of the economy. But this efficiency gain disappeared when population rose again in the 16th century. There is no sign of a connection between a labor scarce economy, and a switch to faster long run economic growth through technological advance.

The most common measure of reproductive behavior is the total fertility rate, which measures children born per woman. However, little work exists measuring male fertility behavior. We use survey data from several waves of the Demographic and Health Surveys (DHS) in eight Sub-Saharan African countries. We document several interesting differences in fertility outcomes of men and women. First, comparing completed fertility by birth cohorts, we find that on average men have more children than women in seven out of eight countries we consider. The gaps are large – reaching up to 4.6 children in Burkina Faso. Positive gaps are possible when populations are growing and men father children with younger women. Such a situation often coincides with polygyny. Indeed, we find that the fertility gap is positively related to the degree of polygyny. Second, we find a lower variance in completed fertility rates for women than for men, especially in high polygyny countries. Third, we find that differences in the desire to have children can largely be explained by differences in realized fertility. Finally, we find that for men, the demographic transition started earlier and was steeper than for women. These novel facts are useful when building theories of fertility behavior.

Life expectancy at birth has more than doubled in Europe since the early 19th century. This demographic trend constitutes a major victory against scarcity, but raises also deep challenges to the Welfare State, concerning the sustainability and the equity of the social protection system. This paper surveys recent developments in the economic analysis of longevity, both at the positive and the normative levels. Taking mortality risks into account is shown to affect the study of the life cycle model significantly, in particular concerning the strength of life horizon effects. It raises also, at the level of normative foundations for policy-making, a dilemma between ex ante and ex post valuations. Finally, we explore the design of policy reforms under varying longevity, in fields including preventive and curative policies, education, pension, and wealth taxation.
