In Senegal mutual health organizations (MHOs) have been present in the greater region of Thies for years. Despite their efforts and the benefits they bring to low-income population, in some areas, take up rates remain low. The authors of Research Paper #14 ran an insurance literacy module, communicating the benefits of health microinsurance and explaining MHOs work, to a randomly selected sample of households in the city of Thies. The effects of the training, and three vouchers offering refunds and additional education were evaluated using a randomized control trial. The authors find that the insurance literacy module had no impact on the demand for health microinsurance, but that their marketing intervention had a significant effect on the take up decisions of households.
