This record contains information on two water service choice experiments. Experiment 1 – Published in Nature for Clean Water (Npj). For this experiment the record contains data collected from 1,560 households in Kwale county on the south coast of Kenya. A sample of 531 handpump locations was used as a sampling frame for a household survey administered in late 2013 and early 2014. 3,500 households took part in this survey of which a random draw of 1,560 households were selected to take part in a choice experiment on water service preferences. Choices included (1) maintenance service provider (public, private), (2) guaranteed days for repairs (2, 4, 6, 8), (3) cash management (treasurer/cash, bank account, mobile money), (4) monthly household payment (USD 0.5, 1.0, 1.5, 2.0). An orthogonal, main effects design generated 10 choice cards, each with two alternatives and a status quo option eliciting 10 choice responses. Participating households could also select a status quo option reflecting community maintenance and the local payment arrangements (commonly cash). The data is presented as prepared for a conditional logit model estimating the main attributes followed by interactions across four hypotheses of behavioural change: (a) multidimensional wealth, (b) education, (c) gender of respondent, and (d) household concerns. The read-me-Npj file describes steps required for estimation of the econometric latent class model specified by a discrete distribution of preferences to estimate heterogeneity. Experiment 2 – Published in Proceedings of the National Academy of Sciences (PNAS). For this experiment the record contains data collected from 1,185 households in Kwale county on the south coast of Kenya. A sample of 531 handpump locations was used as a sampling frame for a household survey administered in late 2013 and early 2014. 3,500 households took part in this survey of which a random draw of 1,185 households were selected to take part in a choice experiment on...
