Evaluating the Effectiveness of Conservation Water-Pricing Programs: Reply

The comment offered by Griffin is correct in asserting that equation (2) in our paper measures the derived demand for consumptive water use, and that its use in our model produces a positive relationship between streamflows and increased consumptive water rates. A slight modification to equation (2) produces a derived demand for delivered water that is consistent with the ambiguous relationship between streamflows and increased water delivery rates that we demonstrate in equation (12). The modified equation is: (2') PyFc(C)E = P, where aY
