【 摘 要 】

It is often argued that engaging inindoor residual spraying in areas with high coverage ofmosquito bed nets may discourage net ownership and use. Thisis just a case of a public program having perverseincentives. This paper analyzes new data from a randomizedcontrol trial conducted in Eritrea, which surprisingly showsthe opposite: indoor residual spraying encouraged netacquisition and use. The evidence points to the role ofimperfect information. The introduction of indoor residualspraying may have made the problem of malaria more salient,leading to a change in beliefs about its importance and toan increase in private health investments.
