Prevention approaches for reproductive health have evolved from an emphasis on individually focused models of behavior change to a recognition that risk reduction occurs within a context of social norms. Prevention programs can be improved by understanding how social structure influences sexual behavior and using that understanding to develop strategies for(More)
Brazil has become a country known as having one of the most extreme examples of the consequences of the hospital-based medicalization of delivery care, while a model of humanization of birth was developed in the State of Ceará in the 1970s. The Government of Japan, through the Japanese International Cooperation Agency (JICA), collaborated with the Federal(More)
Efforts to control disease and improve health in developing countries require increasing collaboration between social and medical scientists. This collaboration should extend from the early stages of technology development to the evaluation and improvement of population-wide interventions. This paper provides an integrating framework for social science(More)
Disease eradication programmes are by definition time bound and require strategies that facilitate timely intervention. Surveillance, which undergirds eradication, also requires timely strategies. Finding such strategies is especially challenging when the target disease is endemic in remote areas, e.g. guinea worm disease, the focus of this study. A(More)
I use neural data collected from an experimental asset market to test the underlying mechanisms that generate peer effects. In a sample of randomly assigned subjects who are given identical information, I find strong causal peer effects in investment decisions. I then use the neural data to construct novel empirical tests that can distinguish between(More)
Diarrheal disease prevention and diarrheal disease control with oral rehydration therapy are major goals of the World Health Organization and the international health community. This paper promotes the use of ethnographic research in this endeavor. It illustrates the use of ethnography in a diarrheal disease prevention and control program in Honduras by(More)
In a large-scale controlled trial in collaboration with the reelec-tion campaign of an Italian incumbent mayor, we administered (randomized) messages about the candidate's valence or ideology. Informational treatments affected both actual votes in the precincts and individual vote declarations. Campaigning on valence brought more votes to the incumbent, but(More)
Surveillance is an essential tool in any campaign to eradicate disease; guinea worm (dracunculiasis), which is targeted for eradication before the year 2000, is no exception. One criterion of an eradicable disease is that it be easy to recognize as the program advances. Few experts doubt that the experience of a meter-long subcutaneous worm protruding(More)
I consider a sequential trading model with both trade timing and information acquisition decisions. Traders benefit from waiting to acquire additional information before trading, but waiting is costly because others may then trade before them. I determine the conditions under which traders rationally panic, rushing to trade to avoid adverse price movements.(More)
