Recreation centers offer a place for young people to play sports and engage in other activities at a marginal cost of MC = 0.25Q. The inverse demand curve for recreation centers is given by P = 10 - 0.25Q, where P is the price of entry and Q measures hundreds of entrants. Recreation centers generate positive externalities because they help get young people off the street and engaged in productive activities. In this case, an action that the government could take to move toward the socially optimal outcome is to implement ____.

The market for toilet paper is characterized by the following inverse demand and supply equations: P = 100 - Q P = MC = 2Q - 197.3 Where P is the price per roll of toilet paper and Q measures millions of rolls of toilet paper. The external marginal cost is 30 cents for each roll of toilet paper produced. The socially optimal price of toilet paper is _____ cents higher than the price under perfect competition.

The marginal cost of pollution is MC = 2Q, while the marginal abatement cost is MAC = 12 - Q. Government regulators incorrectly estimate the marginal abatement cost at MACE = 9 - Q. The level of pollution, measured in tons of glop, is Q. Based on the government's incorrect estimate of marginal abatement costs, the government thinks the socially optimal level of pollution is ____.

Sweet Steel and Molten Metal produce sulfur dioxide emissions during production. The total abatement cost (TAC) and marginal abatement cost (MAC) for each company: Sweet Steel: TACS = 100,000 + 1eS2; MACS = 2eS Molten Metal: TACM = 100,000 + 1.5eM2; MACM = 3eM Where eS and eM represent tons of sulfur dioxide emissions eliminated by each company. Suppose the government wants to eliminate 1,000 tons of sulfur dioxide emissions, so it mandates that each firm cut its emissions by 500 tons. What is the total cost (TACS + TACM) of reducing emissions by 1,000 tons?
