Abstract
This study analyzes the willingness to pay for improved water supply services by households for Haik town. The Contingent Valuation Method (CVM) was utilized to obtain estimates of Willingness to Pay (WTP) for improved domestic water supply services to current and future generations. Analysis of bid function underlying the WTP responses was undertaken, with a range of explanatory variables being investigated. In this contingent valuation survey, we adopted a dichotomous choice with follow-up debriefing questions, as well as open-ended follow-up question to model individual’s WTP. Descriptive analysis as well as two analytical models namely Tobit and Probit model and Ordinary Least Squares (OLS) were used. A sample of 145 household heads was taken. We used stratified sampling method followed by simple random sampling to select the required sample. The survey was conducted using a face- to- face interview to the selected sample of household heads. The study results show that the mean annual WTP of Total Economic Value (TEV) of improved domestic water supply services is about 239.28 Birr per annum, which seems to be a significant amount based on key socioeconomic explanatory variables suggested by economic theory. The mean WTP values are 24.75 and 27.37 cents per Baldi (a 20 liter bucket) for the improved water supply service as calculated from the Tobit and Probit models, respectively. The total WTP amount from the total of 4,590 households in the study area of Haik town is Birr 1,136.03 per Baldi or Birr 4,544.12 per a day at average service fee of 24.75 cent per Baldi. Accordingly, the mean WTP is unlikely to be a realistic value that can gauge the TEV of improved domestic water supply services. However, the study also shows that the TEV of improved domestic water supply services is likely to be difficult to estimate.
