“The Political Economy of Health Epidemics: Evidence from the Ebola Outbreak” [pdf]

Abstract. Health epidemics represent a unique test of governmental accountability. Compared to other disasters, the way the government responds is crucial to stop the contagion and limit the ultimate costs to citizens. However, political motives may distort the allocation of governmental resources. In this paper, I study the response of the Liberian government to the 2014 West Africa Ebola outbreak, and the subsequent effects on citizens’ voting behavior and political perceptions. I combine proprietary data on Ebola cases, novel surveys, and publicly available data on the government’s relief effort and post- outbreak Senatorial election. I first provide evidence of limited governmental response before the arrival of foreign aid, in contrast to improved assistance after aid was provided. I then build a spatio-temporal epidemiological model to estimate the ex-ante optimal allocation of relief effort. I find that the govern- ment misallocated resources towards swing villages affected by the contagion. Voters in turn reacted to the differential response: the incumbent party lost political support in areas hit in the first part of the epidemic, while it did not lose votes in areas hit in the second part and in swing villages. I conclude by discussing the costs to citizens of the political misallocation of resources. The findings provide novel evidence on the presence of strategic electoral motives in the allocation of resources in health epidemics.

“The Local Health Impacts of Natural Resources’ Booms”

Abstract. Do booms in production of natural resources benefit or harm the health of local commu- nities? This paper uses administrative micro-data on local natural resources and health outcomes to study how increases in the production of minerals affect birth outcomes in Brazilian municipalities. I address the endogeneity of production exploiting fluctuations in international commodity prices and the pre-existing spatial variation in mineral endowments. Difference in difference estimates suggest that, following booms in mineral production, local communities experience lower fetal and infant mortality and number of low-weight births. I discuss mechanisms in light of the standard trade-off between the benefits – more wealth from taxes and job opportunities – and costs – corruption or pollution – of natural resources.

“Can individuals beliefs help us understand non-adherence to malaria test results? Evidence from rural Kenya” (with Manoj Mohanan, Wendy Prudhomme OMeara, and Elizabeth L Turner), Economic Research Initiatives at Duke (ERID) Working Paper No. 243. – submitted  [pdf]

Abstract. In malaria-endemic countries about a quarter of test-negative individuals take antimalarials (artemisinin-based combination therapies, ACTs). ACT overuse depletes scarce resources for subsidies and contributes to parasite resistance. As part of an experiment in Kenya that provided subsidies for rapid diagnostic test and/or for ACT conditionally on being positive, we study the relationship between beliefs on malaria status (prior and posterior the intervention), and the decisions to get tested and to purchase ACT. We find that prior beliefs do not explain the decision of getting tested (conditional on the price) and non-adherence to a negative test. However, test-negative individuals who purchase ACT report higher posterior beliefs than those who do not, consistent with a framework in which the formers revise beliefs upward, while the latters do not change or revise downward. Further research is needed to improve adherence to malaria-negative test results.

“Relying Solely on Mobile-Phone Technology: Sampling and Gathering Survey Data in Challenging Settings”submitted

Abstract. Mobile phone technology represents an increasing opportunity for researchers to collect data in challenging settings. This study develops a two-stage data collection methodology, which combines (i) random dialing of phone numbers and an Interactive Voice Recognition survey to sample and screen respondents, and (ii) mobile phone surveys for interviews. Relying solely on mobile phone technology and not requiring any in person contacts, the procedure overcomes the challenges researchers face when a sampling frame is not available or when field-activities are too costly or risky. The feasibility is tested by interviewing 2,200 respondents during the 2014 Ebola outbreak in Liberia.
