Montana is home to a number of firms offering wilderness hunting experiences to wealthy city dwellers. However, the profits of such firms depend on how crowded the "wilderness" is and how many deer are available. Thus, each additional hunting expedition on a given weekend reduces the total profits of each firm. Suppose each expedition costs $1000 to the firm leading it. The firms could instead lead no expedition and accept donations from a pro-animal-rights group of $4000 per weekend.
