Abstract

The objective of this study was to determine whether households who are willing to pay for insecticide-treated nets (ITNs) for themselves are prepared to contribute for the ITNs to be purchased for the indigent community members who cannot afford the nets. This was in the framework of community-based and directed sales for ITNs. The study was conducted in four malaria holoendemic communities in south-eastern Nigeria. Contingent valuation method was used to determine the altruistic willingness to pay (WTP) from randomly selected household heads or their representatives, which was elicited using an open-ended question. Theoretical validity was assessed using the Tobit model. Median altruistic WTP ranged from $0.11 to $0.21 across the four communities (95 Naira=$1). However, using a pooled data from the four communities, the mean was $0.34. In Tobit estimation, altruistic WTP varied significantly with two of the communities; the respondents were resident in, sex, marital status and the amount of savings of the respondent. It also varied significantly with the respondents' WTP for their own ITNs and average monthly household expenditures to treat malaria (p
