Health Capability: Empirical Applications
Job market paper
A multidimensional study of poverty and health capability [Latest version available here]
Abstract: Addressing the multidimensionality of poverty is a major challenge in resource-limited settings where programs for health promotion often homogeneously target poor households. Following the collection of survey data in rural Senegal, I develop a structural equation model (SEM) to estimate and characterize three dimensions of health capability as conceptualized by Prah: self-reported health, empowerment, and healthcare access. In accounting for the multidimensionality of both poverty and health capability at the individual level, I highlight complex and sometimes contradictory effects. In particular, I provide novel evidence that empowerment, a key component of health capability, is lower in individuals living in resource-rich households, even though these individuals are more likely to report optimal levels in health and access to healthcare. My estimates emphasize a need to design differentiated policy and interventions for overall poverty reduction and health promotion. They also show how do to so through a comprehensive characterization of the socio-demographic and economic variables associated with distinct dimensions of health capability.

Chronic hepatitis B in rural Senegal
As project manager of the ANRS12356 AmBASS study (390,000€, PI: Sylvie Boyer & Aldiouma Diallo; 2017-2020), I coordinated the 4 scientific teams based in Dakar and Marseille, recruited and trained the field team of 8 interviewers and monitored data collection during the pilot and the main phase of the study, which administered at-home hepatitis B screening and socio-economic questionnaires to over 3,000 participants. I wrote the protocol paper and participated in the data analysis and scientific publications.
I've also implemented and coordinated the PeCSen study (25,000€, PI: Sylvie Boyer; 2019-2022) which documented linkage to care among people screened for CHB during the AmBASS study. I set up data collection for monitoring visits in 3 health facilities, conducted a micro-costing study, and cooordinated a qualitative study among participants screened for CHB (n=40), and healthcare workers (n=15).
I'm currently managing the data collection of a questionnaire among patients of the Sen-B prospective research cohort to document: (i) socio-economic resources, (ii) direct and indirect costs of CHB management, and (iii) patients reported outcomes. This data will enter an extended cost-effectiveness analysis of CHB management in centralized and decentralized settings in rural sub-Saharan Africa.
