Résumé
A major impediment to improved performance in rural water supply sector of developing countries is inadequate information on the response of consumers to new service options. There are typically several types of water sources available in a village of a developing country. In such cases, the conventional demand function for water will be conditional on the choice of water source. Based on the random utility theory, a discrete/continuous choice model was developed for modeling rural water demand behavior. The discrete water source choice model has been empirically tested by a case study conducted in Kenya. The results suggest that the discrete choice model reasonably characterizes households’ water source choice behavior. The time spent in collecting water from a source is the most significant variable in determining which source is chosen. The households’ income does not impact the water source choice as strongly as was expected. The contingent valuation method is introduced as a promising device for studying water demand behavior in rural areas. The method has been field tested in Haiti. The results show that the bidding game format works better than the open question format. Households’ willingness-to-pay bids are systematically related with the variables suggested by economic theory. The hypotheses developed to test the existence of hypothetical bias, strategic bias and starting point bias in the willingness-to-pay bids were all rejected. A comparison study of water source choice behavior in a contingent market and in an observed market was undertaken in Brazil. In both the contingent valuation villages and the observed behavior village, the head of household’s education level is positively related with the probability of choosing the new system. Farmers are less likely to use the new system. The households’ income level does not have a significant effect on the source choice. In the contingent valuation villages, both strategic bias and starting point bias appear to exist in the willingness-to-pay bids. The hypothesis that there is no behavioral difference in source choice between the contingent market and the observed market is not convincingly conclusive
