Rising Geographic Disparities in US Mortality
The 21st century has been a period of rising inequality in both income and health. In this study, we find that geographic inequality in mortality for midlife Americans increased by about 70 percent from 1992 to 2016. This was not simply because states such as New York or California benefited from having a high fraction of college-educated residents who enjoyed the largest health gains during the last several decades. Nor was higher dispersion in mortality caused entirely by the increasing importance of “deaths of despair,” or by rising spatial income inequality during the same period. ...

Mortality and Economic Growth
Countries with higher economic growth had, on average, higher growth in their crude death rates.

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 ...

Technology Adoption, Mortality, and Population Dynamics
We develop a quantitative theory of mortality and population dynamics, emphasizing individuals' decisions to reduce their mortality by adopting better health technology. Expanded use of this technology reduces the cost of adoption and confers a dynamic externality by increasing the future number of individuals who use the 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 ...
Economic Development and the Evolution of Mortality
Since 1960, the gap in GDP per capita between rich and poor countries has remained wide. Yet the gap in death rates has practically vanished during that period.
Has Better Nutrition Driven Down Mortality Rates?
One popular theory has attributed the decline in death rates to improved nutrition. But an analysis of caloric intake worldwide suggests that there isn’t a strong relationship.

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 ...
