Willingness to Pay for Cleaner Water in Less Developed Countries: Systematic Review of Experimental Evidence

The International Initiative for Impact Evaluation (3ie) recently published a systematic review of the evidence on willingness to pay for clean water in developing countries. The researchers found 5 experimental studies that tested households’ demand for point-of-use water purification technologies (such as chlorine and ceramic filters). The results suggest that while the majority of people understood the importance of cleaner water, and the link to diarrhea, actual willingness to pay for it is often less than the cost of the technology.
