A) Show (graphically) how local and nonlocal interests might differ in assessing the desirability of a project or policy. B) Discuss the issues that create this divergence of interest. C) Use the data in the following table to illustrate this discussion through the lens of the Yellowstone National Park, USA to quantify the benefits, costs and net benefits to locals and the country at large. Table 18-3 Benefits and Costs to Local and Nonlocal People from Wolf Restoration in Yellowstone National Park Local Nonlocal Total Mean WTP* of supporters $20.50 $8.92 Mean WTP of nonsupporters $10.80 $1.52 Estimated number of supporters 391,204 50,152,416 50,543,620 Estimated number of nonsupporters 340,522 25,774,290 26,114,802 Total WTP of supporters $160,553 $8,956,130 $9,116,683 Total WTP of nonsupporters* $68,718 $784,322 $853,040 Net benefits $91,835 $8,171,808 $8,263,643 * WTP = willingness to pay. * These numbers are calculated by assuming a perpetual income stream, discounted at 7 percent, that gave a present value equal to the one-time payments that respondents indicated as their willingness to pay. They are also adjusted to reflect an estimate that actual willingness to pay is only 28.6 per- cent of stated willingness to pay; this is based on the researchers' previous work on the relationship between stated and actual WTP
