The share of the population aged 60 and over is projected to increase in nearly every country in the world during the period 2005--50. Population ageing will tend to lower both labour-force participation and savings rates, thereby raising concerns about a future slowing of economic growth. Our...

Between 2005 and 2050, the share of the population aged 60 and over is projected to increase in nearly every country in the world. Insofar as this shift will tend to lower both labor force participation and savings rates, it raises bona fide concerns about a future slowing of economic growth....

Acemoglu and Johnson (2007) present evidence that improvements in population health do not promote economic growth. We show that their result depends critically on the assumption that initial health has no causal effect on subsequent economic growth. We argue that such an effect is likely,...

The potential economic returns to the demographic transition are high. As countries move from a steady state with high mortality and high fertility to an equilibrium with low mortality and fewer children, lower dependency ratios, higher investment in human and physical capital as well as...

The world has enjoyed huge improvements in population health during the last half century. But major health problems persist, particularly in tropical countries, which are still struggling with infectious diseases while increasingly having to deal with noncommunicable diseases. Several classic...

This paper examines data on urbanization. We review the most commonly used data sources, and highlight the difficulties inherent in defining and measuring the size of urban versus rural populations. We show that differences in the measurement of urban populations across countries and over time...

We analyze the effect of fertility on income per capita with a particular focus on the experience of Europe. For European countries with below-replacement fertility, the high cost of continued low fertility will only be observed in the long run. We show that in the short run, a fall in the...
