Essays On The Adoption Of New Malaria Therapy In Tanzania.

Overview

This dissertation studies the adoption of a new and effective therapy for malaria. In Chapter 1, using data from a pilot program which distributed the new therapy through health facilities in Tanzania, we estimate the impact of introducing the new therapy on the demand for health care. We find that health facility usage increased significantly in the first year after the new therapy's introduction, but declined thereafter, and was no greater than usage at baseline after three years of the program. Most of the ...

Overview

This dissertation studies the adoption of a new and effective therapy for malaria. In Chapter 1, using data from a pilot program which distributed the new therapy through health facilities in Tanzania, we estimate the impact of introducing the new therapy on the demand for health care. We find that health facility usage increased significantly in the first year after the new therapy's introduction, but declined thereafter, and was no greater than usage at baseline after three years of the program. Most of the gains in the demand for health facility care came from reductions in the proportion of sick individuals seeking no treatment at all. Increases in health facility usage associated with the new therapy's introduction were larger for adults than for children, and larger for individuals in less educated households. Our results show that increases in health care quality driven by the introduction of new technologies can induce changes in health care demand, and that these changes can vary over time and across demographic and socioeconomic groups. In Chapter 2, we examine the role of social learning in the adoption of a new and effective therapy for malaria. In our model, individuals learn about the effectiveness of the new therapy by observing the health outcomes of past adopters. We show that misdiagnosis of malaria-which is common in resource-poor settings-- can slow the learning process and stifle adoption. We estimate a learning effect and test for the role of misdiagnosis in learning and adoption. Our empirical strategy accounts for various potential sources of bias, including persistence in the local disease environment and selection into adoption based on the severity of illness. We find that when past adopters have pour health outcomes, the subsequent probability of adoption decreases. This learning effect is smaller in villages where misdiagnosis is more prevalent, and adoption rates in these places are lower over time. Finally, we simulate pairing the introduction of the new therapy with a new diagnostic test for malaria. The results of the simulation show that when misdiagnosis is reduced, learning occurs more quickly and adoption rates are higher.
