Recreation benefits from water pollution control: A further note on benefit evaluation


  • Joe B. Stevens


In my recent paper [Stevens, 1966], estimates of demand functions and angling ‘success elasticities’ were presented for three sport fisheries as a methodological basis for determining recreation benefits from water pollution control. By utilizing success elasticities to shift the demand function for one of the fisheries (D0 to D1 in Figure 1), it was possible to argue that anglers would supply themselves with a lesser quantity of angling at some reduced level of angling success. If the reduced quantity of angling effort (S1) were to be rationed among the original users (D0), a price of AB would be expected. Accordingly, benefits from preventing water pollution would accrue from avoiding this leftward shift of the demand function.
