We explore the role of founding teams in accounting for the post-entry dynamics of startups. While the entrepreneurship literature has largely focused on business founders, we broaden this view by considering founding teams as both the founders and early joiners. We investigate the idea that the...

We examine gender and race differences in education-mortality trends among 25-64 year olds in the United States from 2001-2018. The data indicate that the relationships are heterogeneous with larger mortality reductions for less educated non-Hispanic blacks than other races and mixed results at...

I present a behavioral epidemiological model of the evolution of the COVID epidemic in the United States and the United Kingdom over the past 12 months. The model includes the introduction of a new, more contagious variant in the UK in early fall and the US in mid December. The model is...

Females live longer than males in most parts of the world today. Among OECD nations in recent years, the difference in life expectancy at birth is around four to six years (seven in Japan). But have women always lived so much longer than men? The answer is that they have not. We ask when and why...

We develop a method to compare levels and trends in inequality in mortality in the United States and France in a similar framework. The comparison shows that while income inequality has increased in both the United States and France, inequality in mortality in France remained remarkably low and...

Accurately determining the number of excess deaths caused by the COVID-19 pandemic is hard. The most important challenge is accurately estimating the counterfactual count of baseline deaths that would have occurred in its absence. This analysis used new methods to: estimate this baseline metric;...

Life expectancy varies substantially across local regions within a country, raising conjectures that place of residence affects health. However, population sorting and other confounders make it difficult to disentangle the effects of place on health from other geographic differences in life...

It is now established that mortality and excess mortality from COVID-19 differed across racial and ethnic groups in 2020. Less is known about educational differences in mortality during the pandemic. We examine mortality rates by BA status within sex, age, and race/ethnic groups comparing 2020...

This paper investigates the local impact of biomedical research on mortality in the USA. Causally estimating the marginal value of biomedical research is challenging due to a lack of micro data linking health outcomes to plausibly exogenous variation in research. We create a new linkage between...

This paper explores the long-run health benefits of education for longevity. Using mortality data from the Social Security Administration (1988-2005) linked to geographic locations in the 1940-census data, we exploit changes in college availability across cohorts in local areas. We estimate an...
