Résumé
This article provides an empirical multi-disciplinary strategy that enables to identify prevalence-elastic behaviours influencing the possession of mosquito nets and to assess the relative performance of health centers in promoting the possession of nets in Democratic Republic of Congo (DRC). We use a household survey conducted in 2009 in Haut Katanga, DRC. We combine these data with estimates on malaria prevalence from the Malaria Atlas project. Results show that households behave rationally with respect to the disease, meaning that the cause for a low possession of nets should be found elsewhere. They also show that health centers are not the most effective in promoting possession of bed nets, in areas where they are most needed for malaria control.
