The effect of information on preferences for improved household water supply in Indonesia and Nepal

Information-based interventions are increasingly used to influence preferences or behaviour. Although information does not directly influence behaviour, it is still commonly used because it is inexpensive and provides immediate impacts. The objective of this study is to compare the impacts of information provision on households’ stated preferences for improved water supply systems in Surabaya, Indonesia, and Kathmandu, Nepal. Surabaya and Kathmandu face different challenges in household water supply services. Stated preferences were elicited by using randomized conjoint analysis. In addition to the preference elicitation, the impacts of information on the willingness to pay were also estimated.
