Abstract: | Supply cuts and pricing policies can be used to ration water. The appropriateness of a given policy depends on the losses
in social welfare which it generates. We find some drawbacks with the only method in the previous literature which deals with
the issue of measuring welfare losses under supply cuts. We propose an alternative method. We compare the welfare losses under
supply cuts and a pricing policy during the drought period of 1992–1996 in Seville, Spain, using both methods, and find that
the results vary widely from one method to the other.
