摘要

Objectives: To determine the level of willingness to pay (WTP) for re-treatment of mosquito nets and to comparenthe theoretical validity of WTP estimates from three contingent valuation question formats: the bidding game,nbinary with follow-up technique, and a novel structured haggling technique that mimicked price-taking behaviour innthe study area.nMethods: WTP was elicited from randomly selected respondents from three villages in Southeast Nigeria, usingnpretested interviewer-administered questionnaires. Respondents’ WTP for insecticide-treated nets (ITNs) was . rstnelicited before their WTP for re-treatment of ITNs. Ordinary least-squares regression was used to assess theoreticalnvalidity.nResults: More than 95% of the respondents were willing to pay for re-treatment. The mean WTP was 37.1 Naira,n43.4 Naira and 49.2 Naira in the bidding game, binary with follow-up and structured haggling groups, respectivelyn(US$1.00 ˆ 120 Naira). The WTP estimates elicited across the three question formats were statistically differentn(P50.01). Ordinary least-squares estimation showed that WTP was positively related to many variables, especiallynstated WTP for ITNs (P50.05). Structured haggling generated the highest number of statistically signi. cantnvariables to explain WTP.nConclusions: The three contingent valuation approaches generated different distributions of WTP for net retreatment,npossibly due to their inherent differences. Structured haggling generated the most theoretically validnestimates of WTP. The levels of WTP identi. ed suggest that user fees exceeding 50 Naira per net re-treatmentmayndiscourage demand for the service. This is an important challenge for ITN programmes.
