I use microeconomic estimates of the effect of health on individual outcomes to construct macroeconomic estimates of the proximate effect of health on GDP per capita. I employ avariety of methods to construct estimates of the return to health, which I combine with cross-country and historical...

In Capital in the 21st Century, Thomas Piketty uses the market value of tradeable assets to measure both productive capital and wealth. As a measure of wealth this is problematic because it ignores the value of human capital and transfer wealth, which have grown enormously over the last 300...

Population aging is primarily the result of past declines in fertility, which produced a decades long period in which the ratio of dependents to working age adults was reduced. Rising old-age dependency in many countries represents the inevitable passing of this "demographic dividend." Societies...

Research on intergenerational transmission of wealth has pointed to uncertainty -- about the date of one's own death, for example -- as a potential source of significant bequest flows. In this paper I examine the effects of this same uncertainty on the behavior of those who expect to receive...

This paper addresses two issues. The first is whether demographic change was plausibly responsible for the run-up in stock prices over the last decade, and whether the attempt by the baby boom cohort to cash out of its investments in the period 2010-30 might lead to an “asset meltdown.” The...

We use development accounting techniques to assess the contribution of health to differences in income per capita among countries. Rather than rely on regressions in aggregate data, we build up estimates of the effect of health starting from microeconomic data. We examine both a particular...

We examine the dynamic interaction of the population age structure, economic dependency, and fertility, paying particular attention to the role of intergenerational transfers. In the short run, a reduction in fertility produces a “demographic dividend” that allows for higher consumption. In...

We examine the role of declining mortality in explaining the rise of retirement over the course of the 20th century. We construct a model in which individuals make labor/leisure choices over their lifetimes subject to uncertainty about their date of death. In an environment in which mortality is...
