Demand for environmental quality: averting behaviors impacts and valuation in Southern Ghana

Using a cluster randomized evaluation in Southern Ghana, this paper estimates the impacts of water quality testing and information on averting behaviors, demand and expenditures on water, sanitation and hygiene (WASH). Households are randomly assigned into either child treatment or adult treatment o...
