"A considerable amount of uncertainty surrounds life expectancy at birth, the average length of life. The standard deviation in adult life spans is about 15 years in the U.S., and theory and evidence suggest it is costly. In this paper, I calibrate a standard intertemporal model to show that one...

As of this writing, the wars in Iraq and Afghanistan are in their eighth and tenth years, having accrued nearly a trillion dollars in direct military costs. I review the history of cost forecasts for these ongoing engagements, highlighting the differences across them in scope and accuracy,...

Military spending, fatalities, and the destruction of capital, all of which are immediately felt and are often large, are the most overt costs of war. They are also relatively short-lived. The costs of war borne by combatants and their caretakers, which includes families, communities, and the...

Previous research has revealed much global convergence over the past several decades in life expectancy at birth and in infant mortality, which are closely linked. But trends in the variance of length of life, and in the variance of length of adult life in particular, are less well understood. I...

There is a large and robust correlation between adult health and education, part of which likely reflects causality running from education into health. Less clear is whether education obtained later in life is as valuable for health as are earlier years of schooling, or whether education raises...

A considerable amount of uncertainty surrounds life expectancy, the average length of life. The standard deviation in adult life span is about 15 years in the U.S., and theory and evidence suggest it is costly. I calibrate a utility-theoretic model of preferences over length of life and show...

Starting in 2006, respondents in the U.S. Health and Retirement Study were asked to submit biomarkers and were notified of certain results. Respondents with very high blood pressure were given a card during the interview; all respondents were notified by mail of their BP, hemoglobin A1c, and...

Recent military engagements in Iraq (OIF) and Afghanistan (OEF) raise questions about the effects on service members of overseas deployment, which can include service in a combat or war zone, exposure to casualties, or both. The 2010 National Survey of Veterans, which asked a broad cross section...

This study quantifies the economic effects of two major immigration policies aimed at legalizing undocumented individuals that entered the United States as children and completed high school: Deferred Action for Childhood Arrivals (DACA) and the DREAM Act. The former offers only temporary legal...
