Using the Becker-DeGroot-Marschak (BDM) mechanism, we estimate the willingness-to- pay (WTP) for and impact of clean water technology through a field experiment in Ghana. Although WTP is low relative to the cost, demand is relatively inelastic at low prices. In the short-run, treatment effects are positive – the incidence of children’s diarrhea falls by one third – and consistent throughout the WTP distribution. After a year, use has fallen, particularly for those with relatively low valuations. Strikingly, the long-run average treatment effect is negative for those with valuations below the median. Combining estimated treatment effects with individual willingness-to pay measures implies households’ valuations of health benefits are much smaller than those typically used by policymakers. Finally, we explore differences between BDM and take-it-or-leave-it valuations and make recommendations for effectively implementing BDM in the field.
