Under the assumption of no unmeasured confounders, a large literature exists on methods that can be used to estimating average treatment effects (ATE) from observational data and that spans regression models, propensity score adjustments using stratification, weighting or regression and even the...

Federal and state laws passed in the late 1990 increased considerably postpartum stays for newborns. Using all births in California over the 1995-2001 period, 2SLS estimates suggest that for the average newborn impacted by the law, increased treatment intensity had modest and statistically...

Many studies find that households increase their consumption after the receipt of expected income payments, a result inconsistent with the life-cycle/permanent income hypothesis. Consumption can increase adverse health events, such as traffic accidents, heart attacks and strokes. In this paper,...

We document a within-month mortality cycle where deaths decline before the 1st day of the month and then spike after the 1st. This cycle is present across a wide variety of causes and demographic groups. A similar cycle exists for a range of activities, suggesting the mortality cycle may be due...

The U.S. health system has been described as the most competitive, heterogeneous, inefficient, fragmented, and advanced system of care in the world. In this paper, we consider two questions: First, is the U.S. health care system productively efficient relative to other wealthy countries, in the...

The program project Early Indicators of Later Work Levels, Disease and Death investigates how socioeconomic and environmental factors in early life can shape health and work levels in later life. Project researchers have approached this problem by creating a life-cycle sample that permits a...

This paper models how the evolving field of pharmacogenomics (PG), which is the science of using genomic markers to predict drug response, may impact drug development times, attrition rates, costs, and the future returns to research and development (R&D). While there still remains an abundance...

Childhood obesity around the world, and particularly in the United States, is an escalating problem that is especially detrimental as its effects carry on into adulthood. In this paper we employ the 1979 Child-Young Adult National Longitudinal Survey of Youth and the 1997 National Longitudinal...

The escalating rate of obesity in the US highlights the importance of understanding the causes for this rise. In this paper I employ the First, Second, and Third National Health and Nutrition Examination Surveys to estimate a structural model of the determinants of adult obesity. To control for...

This paper examines the pathways by which individuals transition from healthy to disabled. Because of the high prevalence and costs associated with disability, understanding these pathways is critical to developing interventions to prevent or minimize disability. We compare two estimates of...
