The U.S. EPA says that a typical sport fisherman working the Great Lakes would pay $4.58 for the privilege of catching a single walleye/pike, but would gladly fork over $7.99 to land a trout, or...

7. DOE EIA Form 861. EIA-861 does not provide DSM expenditures by customer class; we assume that utilities with high overall DSM expenditures include residential programs in their portfolio.
8. We defined “high” DSM expenditures as $0.75/MWh or greater, which results in a “high” label for energy providers with DSM expenditures in roughly the upper quartile of our sample. Where utilities did not report a value for DSM expenditures on EIA-861, we assume expenditures were, in fact, zero.
9. Applied microeconomics typically models customer responsiveness based on marginal price changes, see Jerry A. Hausman, "The Econometrics of Nonlinear Budget Sets," Econometrica, Vol.53, No.6, pp.1255-1282.
10. Percentage change in total sales = (share of sales with marginal rate at tier-1 rate * price elasticity for small users * percentage of tier-1 rate change) + (share of sales with marginal rate at tier-2 rate * price elasticity for large users * percentage of tier-2 rate change). Thus, (25 percent * -0.05 * -15 percent) + (75 percent * -0.10 * +25 percent) = 1.7 percent. Changing the tier-1 sales share assumption to 50 percent would result in a total sales change of -0.9 percent.
