Occupational licensing laws have been relaxed in a large number of U.S. states to give nurse practitioners the ability to perform more tasks without the supervision of medical doctors. We investigate how these regulations may affect wages, employment, costs, and quality of providing certain...

Medical care at the end of life, which is often is estimated to contribute up to a quarter of US health care spending, often encounters skepticism from payers and policy makers who question its high cost and often minimal health benefits. It seems generally agreed upon that medical resources are...

Drugs and crime are known to be correlated, but the direction of causality and the magnitude of the relationship have not been well established. We take a new approach to estimating this relationship and examine a little used, multi-site dataset of 3,500 inner-city drug users entering treatment....

Excess body weight or body fat hinders performance of military duties. As a result, the U.S. military has weight-for-height and percent body fat standards for enlistment. This paper estimates the number and percent of military-age civilians who meet, and do not meet, the current active duty...

The impact of labor turnover on productivity has received a great deal of attention in the literature on organizations. We consider the impact of cohort turnover -- the simultaneous exit of a large number of experienced employees and a similarly sized entry of new workers -- on productivity in...

Since 2000, premiums for employer-provided health insurance have increased by 59 percent with little corresponding increase in the generosity of coverage. The effect of this increase in costs on wages and employment will depend on workers' valuation of the benefit, the elasticities of labor...

Productivity spillovers are often cited as a reason for geographic specialization in production. A large literature in medicine documents specialization across areas in the use of surgical treatments, which is unrelated to patient outcomes. We show that a simple Roy model of patient treatment...

We examine whether the job characteristics of physical demands and environmental conditions affect individual's health. Five-year cumulative measures of these job characteristics are used to reflect findings in the biologic and physiologic literature that indicate that cumulative exposure to...

Previous work shows that higher levels of education quality (as measured by international student achievement tests) increases growth rates of national income. This paper begins by confirming those findings in an analysis involving more countries over more time with additional controls. We then...

While numerous studies have examined how health affects retirement behavior, few have analyzed the impact of retirement on subsequent health outcomes. This study estimates the effects of retirement on health status as measured by indicators of physical and functional limitations, illness...
