We add health and longevity to a standard model of life cycle saving and show that, under plausible assumptions, increases in longevity lead to higher savings rates at every age, even when retirement is endogenous. In a stable population these higher savings rates are offset by increased old age...

Micro-based and macro-based approaches have been used to assess the effects of health on economic growth. Micro-based approaches aggregate the return on individual health from Mincerian wage regressions to derive the macroeconomic effects of population health. Macro-based approaches estimate a...

There are two prominent methods to assess the effects of health on economic growth. The first is based on the estimated returns on health by means of Mincer wage regressions that are aggregated to derive the macroeconomic effects of population health. The second approach is based on the...

Economists use micro-based and macro-based approaches to assess the macroeconomic return to population health. The macro-based approach tends to yield estimates that are either negative and close to zero or positive and an order of magnitude larger than the range of estimates derived from the...

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,...

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...
