The Impact of Subsidized Antimalarials on Treatment Seeking Behavior
I investigate the effect of the first multi-country antimalarial subsidy on the type and source of treatment taken for children under five years of age reporting a fever. I use nationally representative, cross-sectional survey data from sixteen malaria endemic African countries over a ten year period. My research design exploits the within country variation in malaria treatment subsidies. Artemisinin-based Combination Therapies (ACTs) are the recommended first line treatment for uncomplicated malaria. Overall, the ACTs subsidy achieved two of its main objectives. Among children reporting a fever, countries offering subsidized ACTs showed a statistically significant 8.1 percentage point increase in ACTs taken from private sector outlets compared to countries not participating in the subsidy. To complement these results, the ACTs subsidy was associated with a decrease of 10.7 percentage points in children taking lesser effective antimalarial monotherapies from any source for participating countries. However, the effect of the ACTs subsidy was not consistent among the four countries participating in the subsidy. Uganda showed the desired response with the greatest magnitude to the subsidy whereas no significant effect was observed in Ghana. The mixed results among countries participating in the ACTs subsidy may be due to differences in ACTs availability, price, market share, and supporting interventions.
