This paper examines the hypothesis that the persistence of low spatial and marital mobility in rural India, despite increased growth rates and rising inequality in recent years, is due to the existence of sub-caste networks that provide mutual insurance to their members. Unique panel data...

This paper characterizes the welfare gains from redistributive taxation and social insurance in an environment where the private sector provides partial insurance. We analyze stylized models in which adverse selection, pre-existing information, or imperfect optimization in private insurance...

Health insurance may play an important role not only in immediate access to care but in the management of chronic disease, which would have implications for long-run care needs as well as health outcomes. Such causal connections are often difficult to establish, but we use Oregon's 2008 Medicaid...

Improvements in medical treatment have contributed to rising health spending. Yet there is relatively little evidence on whether the spending increase is "worth it" in the sense of producing better health outcomes of commensurate value--a critical question for understanding productivity in the...

Health systems globally face increasing morbidity and mortality from chronic disease, yet many--especially in low- and middle-income countries--lack strong primary care. We analyze China's efforts to promote primary care management for insured rural Chinese with chronic disease, analyzing unique...

Alzheimer's Disease (AD) affects one in ten people aged 65 or older and is the most expensive disease in the United States. We describe the central economic questions raised by AD. While there is overlap with the economics of aging, the defining features of the 'economics of Alzheimer's Disease'...

This paper studies racial/ethnic disparities in awareness of chronic diseases using biomarker data from the 2006 HRS. We estimate a 3-step sequential probit model which accounts for selection into: (1) participating in biomarker collection; (2) having illness (hypertension or diabetes); (3)...

It is well known that disability rates among the American elderly have declined over the past decades. The cause of this decline is less well established. In this paper, we test one important possible explanation--that the decline in disability occurred because of chronic disease prevention...

Unlike the widespread adoption of information and communications technology (ICT) in much of the economy, adoption of ICT in clinical care is limited. We examine how a number of not previously emphasized features of the health care and ICT markets interact and exacerbate each other to create...

One in twelve Americans suffers from asthma and its annual costs are estimated to exceed $50 billion. Simultaneously, the root causes of the disease remain unknown. A recent hypothesis speculates that maternal vitamin D levels during pregnancy affect the probability the fetus later develops...
