Mortality Reductions: Fast for Poorer Nations, Slow for Richer Nations
The same increase in life expectancy took longer for a sample of today’s richer countries than it did for some of today’s poorer countries, but it also occurred earlier.

The Role of Infant Mortality in Closing the Life Expectancy Gap
The difference in life expectancy between rich and poor countries has narrowed since 1970, owing in large part to decreases in infant mortality.

Technology Adoption, Mortality, and Population Dynamics
We develop a quantitative theory of mortality and population dynamics. We emphasize individuals' decisions to reduce their mortality by adopting better health technology. Adoption confers a dynamic externality: Adoption becomes cheaper as more individuals use better technology. Our model generates a diffusion curve, whose shape dictates the pace of mortality reduction. The model explains historical trends in mortality rates and life expectancies at various ages, and population dynamics in Western Europe. Unlike Malthusian theories based solely on income, ours is consistent with the observed ...

Who’s Driving a Recent Decline in Life Expectancy?
Life expectancy in the U.S. and most other G-7 nations declined from 2019 to 2021. For the U.S., it was the biggest two-year drop since the early 1920s.

Technology Adoption, Mortality, and Population Dynamics
We develop a quantitative theory of mortality and population dynamics. We emphasize individuals' decisions to reduce their mortality by adopting better health technology. Adoption becomes cheaper as more individuals use better technology. It also confers a dynamic externality by increasing the future number of individuals who use the better technology. Our model generates a diffusion curve whose shape dictates the pace of mortality reduction. The model explains historical trends in mortality rates and life expectancies at various ages and population dynamics in Western Europe. Unlike ...

Demographics and Real Interest Rates Across Countries and Over Time
We explore the implications of demographic trends for the evolution of real interest rates across countries and over time. To that end, we develop a tractable three-country general equilibrium model with imperfect capital mobility and country-specific demographic trends. We calibrate the model to study how low-frequency movements in a country's real interest rate depend on its own and other countries' demographic factors, given a certain degree of financial integration. The more financially integrated a country is, the higher the sensitivity of its real interest rate to global developments ...
The Evolution of the Racial Gap in U.S. Life Expectancy
White Americans live longer than Black Americans, but the gap has been narrowing. What has been driving that in recent decades?
Working Paper
Explaining Educational Attainment across Countries and over Time
Consider the following facts. In 1950, the richest countries attained an average of 8 years of schooling whereas the poorest countries 1.3 years, a large 6-fold difference. By 2005, the difference in schooling declined to 2-fold because schooling increased faster in poor than in rich countries. What explains educational attainment differences across countries and their evolution over time? We consider an otherwise standard model of schooling featuring non- homothetic preferences and a labor supply margin to assess the quantitative contribution of productivity and life expectancy in explaining ...
