... on, self rated health status, prior possession of a bed net, and self rated ability to pay to be significantly associated with maximum openended WTP (p<0.005). While, a recent experience with a malaria episode, nuisance of mosquito bites, and the price of an ITN were associated with the probability of giving an affirmative response for the discrete choice question (p<0.005). ITNs characteristics have different relative importance in determining consumer's preferences of and procurement decisions for an ITN. Respondents were willing to pay lower average prices compared to prices presented to them suggesting inability to pay for the market ITN prices. Conclusion: WTP studies conducted in communities before the interventions are implemented, could be useful in providing local information for understanding the local market structure, designing behavioural change messages and establishing affordable local prices and levels of subsidies for promoting potential demand for ITNS.
