The Association Between Poverty and Mortality
The world’s population is increasing mostly in poor countries as a result of both reduced mortality and relatively high fertility.
Journal Article
Mortality and Economic Growth
Countries with higher economic growth had, on average, higher growth in their crude death rates.

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.

Killer Debt: The Impact of Debt on Mortality
This study analyzes the effect of individual finances (specifically creditworthiness and severely delinquent debt) on mortality risk. A large (approximately 170,000 individuals) subsample of a quarterly panel data set of individual credit reports is utilized in an instrumental variables design. The possibility of the reverse causality of bad health causing debt and death is removed by instrumenting for individual finances post 2011 using the exposure to the housing crisis based on their 2005 residence. Worsening creditworthiness and increases in severely delinquent debt are found to lead to ...
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.

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. ...

Social Security Reform with Heterogeneous Mortality
Using a heterogeneous-agent, life-cycle model of Social Security claiming, labor supply and saving, we consider the implications of lifespan inequality for Social Security reform. Quantitative experiments show that welfare is maximized when baseline benefits are independent of lifetime earnings, the payroll tax cap is kept roughly unchanged, and claiming adjustments are reduced. Eliminating the earnings test and the income taxation of Social Security benefits provides additional gains. The Social Security system that would maximize welfare in a "2050 demographics" scenario, characterized by ...

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 ...
