The quality of medical care received by patients varies for two reasons: differences in doctors' competence or differences in doctors' incentives. Using medical vignettes, the authors evaluated competence for a sample of doctors in Delhi. One month later, they observed the same doctors in their...

The quality of medical care is a potentially important determinant of health outcomes. Nevertheless, it remains an understudied area. The limited research that exists defines quality either on the basis of drug availability or facility characteristics, but little is known about how provider...

Between 2000 and 2002, the authors followed 1621 individuals in Delhi, India using a combination of weekly and monthly-recall health questionnaires. In 2008, they augmented these data with another 8 weeks of surveys during which households were experimentally allocated to surveys with different...

This paper provides an overview of recent work on quality measurement of medical care and its correlates in four low and middle-income countries-India, Indonesia, Tanzania, and Paraguay. The authors describe two methods-testing doctors and watching doctors-that are relatively easy to implement...

The authors develop a method in which vignettes-a battery of questions for hypothetical cases-are evaluated with item response theory to create a metric for doctor quality. The method allows a simultaneous estimation of quality and validation of the test instrument that can be used for further...

Open defecation is exceptionally widespread in India, a county with puzzlingly high rates of child stunting. This paper reports a randomized controlled trial of a village-level sanitation program, implemented in one district by the government of Maharashtra. The program caused a large but...

Unannounced visits were made to health clinics in Bangladesh to determine what proportion of medical professionals were at their assigned post. Averaged over all job categories and types of facility, the absentee rate was 35 percent. The absentee rate for physicians was 40 percent at the larger...

This article presents an approach to public policy in health that comes directly from the literature on public economics. It identifies two characteristic market failures in health. The first is the existence of large externalities in the control of many infectious diseases that are mostly...

Governments in many low- and middle-income countries are developing health insurance products as a complement to tax-funded, subsidized provision of health care through publicly operated facilities. This paper discusses two rationales for this transition. First, health insurance would boost...

This paper presents asymptotic theory and Monte-Carlo simulations comparing maximum-likelihood bivariate probit and linear instrumental variables estimators of treatment effects in models with a binary endogenous treatment and binary outcome. The three main contributions of the paper are (a)...
