The potential epidemiological impact of preventive HIV vaccines on the HIV epidemic in Southern India is examined using a mathematical deterministic dynamic compartmental model. Various assumptions about the degree of protection offered by such a vaccine, the extent of immunological response of...

This study assesses the potential demand by the public sector for a preventive HIV/AIDS vaccine in Brazil and the costs of alternative strategies for a vaccination program. Brazil has a mature AIDS epidemic: the percent of the population living with HIV or AIDS (about 0.6 percent of adults) is...

Recent studies have used homicide rates, police statistics, and crime victimization surveys to pinpoint violent areas. The author argues that these useful measures of crime, and violence underestimate certain types of violence (especially non-economic violence) and key dimensions of violence...

The authors review the implications for social policy in developing countries of two major justifications for fertility reduction: the externality argument and the income redistribution argument. First they set out the arguments. In terms of how policy affects the poor, they show that the...

Both projects described here, Matadi and Kananga, helped health providers in those two cities offer clinical family planning services. But their approaches differed markedly. The family education program in Matadi concentrated on pioneering community-based distribution of contraceptives, with...

Africa has historically provided the geographical flashpoint of ethical issues relating to family planning programs. Until recently in Sub-Saharan Africa, advocacy of family planning by non-Africans was unacceptable and by Africans politically inadvisable. This has changed in the 1980s. The...

The author tests the hypothesis that education improves health and increases people's life expectancy. Smoking histories-reconstructed from retrospective data in the National Health Interview Surveys in the United States-show that after 1950, when information about the dangers associated with...

The authors examine how a government-run cash transfer program targeted to poor mothers in rural Ecuador influenced the health and development of their children. This program is of particular interest because, unlike other transfer programs that have been implemented recently in Latin America,...

The authors delineate two different algorithms for the purchase of AIDS vaccines, to show how differences in policy objectives can greatly affect projections of the number of courses of vaccine that will be needed. They consider a hypothetical vaccine costing ten dollars to produce, and offering...

The effect of community characteristics, in general, and access to family planning services, in particular, on contraceptive use has received considerable attention for several reasons. First, from a policy perspective, increasing access to contraception is the most direct intervention available...
