The author addresses two issues. First, how can health inequalities be measured so as to take into account policymakers'attitudes toward inequality? The Gini coefficient and the related concentration index embody one particular set of value judgments. Generalizing these indexes allows...

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...

Data from the British National Child Development Study show that, among 33-year-olds, ill health (as measured by cardinalized responses to a question on self-assessed health) is concentrated among the worse off. The authors seek to decompose the inequalities in health status into their...

The authors propose a method for decomposing inequalities in the health sector into their causes, by coupling the concentration index with a regression framework. They also show how changes in inequality over time, and differences across countries, can be decomposed into the following: Changes...

Over the past three decades, China has made commendable strides in improving the health status of its population. Between 1965 and 1995, its infant mortality rate declined from 90 per 1,000 live births to 36. During the same period, life expectancy at birth rose from 55 to 69 years and the...

The authors use cross-national social, political, economic, and institutional data to explain why some countries have stronger immunization programs than others, as measured by diphtheria-tetanus-pertussis (DTP) and measles vaccine coverage rates and the adoption of the hepatitis B vaccine....

The author empirically explores the relationship between household poverty and the incidence and treatment of fever--as an indicator of malaria--among children in Sub-Saharan Africa. He uses household Demographic and Health Survey data collected in the 1990s from 22 countriesin which malaria is...

By the end of 1999, an estimated 24.5 million Africans were living with HIV/AIDS, accounting for more that seventy percent of all global infections. In Tanzania, an estimated 1.3 million people (of a total population of 33 million) were believed to be infected with HIV, and 140,000 had already...

Teams from two institutions studied the economic impact of health status on productivity and income. They studied whether onchocercal skin disease caused economic damage to the labor force at a coffee plantation in southwest Ethiopia, and how much. The research team estimated the daily wage...

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...
