The village presently owns the land and allows all residents to graze cows freely. Some members of the village council have suggested that the land is being overgrazed. Is this likely to be true?

三、Calculation：（每题 20 分，共 40 分） 1. A firm faces the following average revenue (demand) curve: P = 120 - 0.02Q where Q is weekly production and P is price, measured in cents per unit. The firm’s cost function is given by C = 60Q + 25,000. Assume that the firm maximizes profits. a. What is the level of production, price, and total profit per week? b. If the government decides to levy a tax of 14 cents per unit on this product, what will be the new level of production, price, and profit? 2 In a market for dry cleaning, the inverse market demand function is given by P = 100− Q and the (private) marginal cost of production for the aggregation of all dry cleaning firms is given by MC =10 + Q . Finally, the pollution generated by the dry cleaning process creates external damages given by the marginal external cost curve MEC = Q. Calculate the output and price of dry cleaning if it is produced under competitive conditions absent regulation. a Determine the socially efficient price and output of dry cleaning. b Determine the tax that would result in a competitive market producing the socially efficient output. c Calculate the output and price of dry cleaning if it is produced under monopolistic conditions without regulation. d Determine the tax that would result in a monopolistic market producing the socially efficient output. e Assuming that no attempt is made to monitor or regulate the pollution, which market structure yields higher social welfare? Discuss. 得分 阅卷教师
