5-5. A nation's government has determined that mass transit, such as bus lines, helps alleviate traffic con- gestion, thereby benefiting both individual auto commuters and companies that desire to move products and factors of production speedily along streets and highways. Nevertheless, even though several private bus lines are in service, the country's commuters are failing to take into account the positive externality associated with the use of mass transit. a. Discuss, in the context of demand-supply analysis, the essential implications of commuters' failure to take into account the positive externality associated with bus ridership. b. Explain a government policy that might be effective in achieving the socially efficient use of bus services.

The private cost of producing the 160th unit of output is $16 b. The social cost of producing the 160th unit of output is $22. c. d. The external cost of producing the 160th unit of output is $6. All of the above are correct.
1. True or False d. In the presence of an unpriced negative externality such as roadway congestion, marginal private benefit will be less than marginal social cost. e. The optimal level of roadway congestion is zero. f. The optimal congestion toll on a road would be the difference between marginal benefit and marginal private cost at the optimal level of road usage.

2. The effect of negative externalities on the optimal quantity of consumption Consider the market for paper. Suppose that a paper factory dumps toxic waste into a nearby river, creating a negative externality for those living downstream from the factory. Producing an additional tonne of paper imposes a constant external cost of $105 per tonne. The following graph shows the demand (private value) curve and the supply (private cost) curve for paper. Use the purple points (diamond symbol) to plot the social cost curve when the external cost is $105 per tonne.

5.. "Since a public good is enjoyed by all members of society, willingness to pay for the good will not diminish as the amount produced increases." Evaluate and use an example to support your answer. This statement is (correct incorrect). Public goods face (increasing, constant, diminishing ) returns like any other good. Consider the number of highways in a town, for example. Citizens of a town are very willing to pay for the first highway, as it produces large gains to the town. Successive highways produce (more and more, less and less ) willingness to pay because the citizens face lower and lower gains from the increased number of highways. In a town of, say 20,000, 15 highways (would, would not) produce much more benefit than just 2 or 3 highways because of ( increasing, constant, diminishing ) returns.
3. The effect of negative externalities on the optimal quantity of consumption Consider the market for electricity. Suppose that a power plant dumps byproducts into a nearby river, creating a negative externality for those living downstream from the plant. Producing additional electricity imposes a constant per-unit external cost of $300. The following graph shows the demand (private value) curve and the supply (private cost) curve for electricity. Use the purple points (diamond symbol) to plot the social cost curve when the external cost is $300 per unit. 1000 900 800 700 600 500 400 300 200 PRICE (Dollars per unit of electricity) 100 ப 0 0 1 2 ° 3 0 ° 4 ° QUANTITY (Units of electricity) 5 6 Supply (Private Cost) Demand (Private Value) Social Cost ?

6. A paper mill discharges chemicals into a river that washes the shores of a downstream resort area. The private cost, social cost, and marginal benefit associated with the production of paper are given by the following equations: PMC = 5 + Q, SMC = 10 + 2Q, and MB = 35 -0.5Q. a. Provide a labelled diagram to illustrate how the competitive free market will not produce the socially optimal amount of output. b. Illustrate the efficiency loss. C. Illustrate how a per-unit tax could be used to correct this problem.
3. The effect of negative externalities on the optimal quantity of consumption Consider the market for steel. Suppose that a steel manufacturing plant dumps toxic waste into a nearby river, creating a negative externality for those living downstream from the plant. Producing an additional ton of steel imposes a constant external cost of $140 per ton. The following graph shows the demand (private value) curve and the supply (private cost) curve for steel. Use the purple points (diamond symbol) to plot the social cost curve when the external cost is $140 per ton.
