N( N > 1) logging firms use a forest to collect timber. Each firm /, / = 1,2,..., N must choose how many trees to cut. 9; The benefit of cutting a tree is A - BC per tree, where O is the total quantity of trees cut in the forest. The marginal cost of cutting a tree is C. Firms do not face any fixed costs. Which statement is TRUE? O Socially optimal number of trees cut increases when the number of logging firms increases Socially optimal number of trees cut decreases when the number of logging firms increases. Socially optimal number of trees cut does not change when the number of logging firms increases. Socially optimal number of trees cut fist increases and then decreases when the number of logging firms increases
