I examine treatment effect heterogeneity within an experiment to inform external validity. The local average treatment effect (LATE) gives an average treatment effect for compliers. I bound and estimate average treatment effects for always takers and never takers by extending marginal treatment...

We investigate whether information technology can help physicians more efficiently acquire new knowledge in a clinical environment characterized by information overload. Our analysis makes use of data from a randomized trial as well as a theoretical model of the influence that information...

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...

The US health care sector is, by most accounts, extraordinarily inefficient. Health information technology (IT) has been championed as a tool that can transform health care delivery. Recently, the federal government has taken an active role in promoting health IT diffusion. There is little...

One explanation for insufficient use of primary care in the U.S. is a lack of trust between patients and providers - particularly along racial lines. We assess the role of racial concordance between patients and medical providers in driving use of preventive care and the implications for patient...

Obtaining better information on the quality of health care providers is one of the most pressing issues in health policy today. In this paper we (1) develop a new method for measuring quality of care that overcomes the key limitations of available quality measures, and (2) apply this method to...

We investigate the effect of managed care on the health care system, focusing on the effects managed care could have on the number and types of health care providers and their efficiency. By influencing providers, managed care may change the structure and performance of the entire health care...

This paper reviews the public sector role in the provision of health care. A first role of the government is to use tax policy to correct externalities associated with individual behaviors. Estimates suggest that the external effects of many `sins' such as alcohol consumption are greater than...

The aim of this paper is to assess the impact of the Community Health Center (CHC) on health levels in the U.S. Using infant mortality as the underlying health indicator, a time series of large counties as the data set, and multivariate regression techniques, we investigate the extent to which...
