According to the Coase theorem, in the presence of externalities

private parties can bargain to reach an efficient outcome.

According to the Coase theorem, private markets will solve externality problems and allocate resources efficiently as long as

private parties can bargain with sufficiently low transaction costs.

Research into new technologies

provides positive externalities because it creates knowledge others can use.

Refer to Figure 9-13. Consumer surplus before trade is

$3,600.

Refer to Figure 9-15. Producer surplus with the tariff is

C + G.

Refer to Table 13-7. What is the value of G?

Julia prepares tax returns and does bookkeeping. Last year her revenues from the tax and bookkeeping business were $150,000, and her expenses for the business were $15,000. When she started her tax and bookkeeping business, Julia gave up her supplemental job doing in-home pet sitting. She used to earn $10,000 per year from pet sitting. Assume that she incurred no costs for her pet sitting business. Julia's implicit costs are

$10,000

Kelly is willing to pay $5.20 for a gallon of gasoline. The price of gasoline at her local gas station is $3.80. If she purchases ten gallons of gasoline, then Kelly's consumer surplus is

$14.

Refer to Figure 8-13. Suppose the government places a $5 per-unit tax on this good. The producer surplus after this tax is

$15.

Tom walks Bethany's dog once a day for $50 per week. Bethany values this service at $60 per week, while the opportunity cost of Tom's time is $30 per week. The government places a tax of $35 per week on dog walkers. After the tax, what is the loss in total surplus (per week)?

$30

Scenario 13-19 Doreen's Dairy produces and sells Swiss cheese. Last year, it produced 7,000 pounds and sold each pound for $6. In producing the 7,000 pounds, the dairy incurred variable costs of $28,000 and a total cost of $40,000. In producing the 7,000 pounds of cheese, the firm's average variable cost was

$4.00.

Refer to Table 10-2. How large would a subsidy need to be in this market to move the market from the equilibrium level of output to the socially-optimal level of output?

Scenario 13-18 Farmer Jack is a watermelon farmer. If Jack plants no seeds on his farm, he gets no harvest. If he plants 1 bag of seeds, he gets 30 watermelons. If he plants 2 bags of seeds, he gets 50 watermelons. If he plants 3 bags of seeds he gets 60 watermelons. A bag of seeds costs $100, and the costs of seeds are his only costs. Which of the following statements is (are) true? (i) Farmer Jack experiences decreasing marginal product. (ii) Farmer Jack's production function is nonlinear. (iii) Farmer Jack's total cost curve is linear.

(i) and (ii) only

Refer to Table 13-3. At which number of workers does diminishing marginal product begin?

Refer to Figure 9-9. Consumer surplus in this market after trade is

For a large firm that produces and sells automobiles, which of the following costs would be a variable cost?

All of the above are correct.

Refer to Figure 9-2. This country

All of the above are correct.

Import quotas and tariffs produce similar results. Which of the following is not one of those results?

Consumer surplus of domestic consumers increases.

Refer to Table 7-2. If the price of Vanilla Coke is $6.90, who will purchase the good?

David and Laura

Refer to Figure 8-8. After the tax goes into effect, producer surplus is the area

J

Refer to Figure 13-3. Which of the following statements best captures the nature of the underlying production function (not pictured)?

Output increases at a decreasing rate with additional units of input.

Refer to Figure 9-4. Which of the following statements is accurate?

Producer surplus with trade is $375

Suppose that electricity producers create a negative externality equal to $6 per unit. Further suppose that the government imposes a $8 per-unit tax on the producers. What is the relationship between the after-tax equilibrium quantity and the socially optimal quantity of electricity to be produced?

The after-tax equilibrium quantity is less than the socially optimal quantity.

Which of the following is not a reason why government agencies subsidize basic research?

The government wants to attract the brightest researchers away from private research firms.

The difference between a corrective tax and a tradeable pollution permit is that

a corrective tax sets the price of pollution and a permit sets the quantity of pollution.

If an allocation of resources is efficient, then

all potential gains from trade among buyers are sellers are being realized.

Refer to Figure 9-14. When the country for which the figure is drawn allows international trade in crude oil,

consumer surplus for domestic crude-oil consumers decreases.

Refer to Figure 8-23. If the economy is at point B on the curve, then a small decrease in the tax rate will

decrease the deadweight loss of the tax and increase tax revenue.

The government provides public goods because

free-riders make it difficult for private markets to supply the socially optimal quantity.

Which of the following explains why long-run average cost at first decreases as output increases?

gains from specialization of inputs

If the Korean steel industry subsidizes the steel that it sells to the United States, the

harm done to U.S. steel producers is less than the benefit that accrues to U.S. consumers of steel.

Suppose that alcohol consumption creates a negative externality. What can the government do to equate the equilibrium quantity of alcohol and the socially optimal quantity of alcohol?

impose a tax on alcohol that is equal to the per-unit externality

Refer to Figure 8-12. Suppose a $3 per-unit tax is placed on this good. The tax causes the price paid by buyers to

increase by $2.

If marginal cost is rising,

marginal product must be falling

All remedies for externalities share the goal of

moving the allocation of resources toward the socially optimal equilibrium.

A seller is willing to sell a product only if the seller receives a price that is at least as great as the

seller's cost of production.

Suppose the government imposes a tax of P' - P'''. The area measured by I+J+K+L+M+Y represents

total surplus before the tax.

Refer to Figure 9-3. If China were to abandon a no-trade policy in favor of a free-trade policy,

total surplus in the Chinese economy would increase.

One of the basic principles of economics is that markets are usually a good way to organize economic activity. This principle is explained by the study of

welfare economics

Refer to Figure 9-26. As a result of opening up the baseball market to international trade, the U.S. will​

​export 600 baseballs.
