Table 4The following table shows the marginal costs for each of four firms (A, B, C, and D) to eliminate units of pollution from their production processes. For example, for Firm A to eliminate one unit of pollution, it would cost $54, and for Firm A to eliminate a second unit of pollution it would cost an additional $67. Unit to be eliminated A B C D First unit First unit 54 57 54 62 Second unit 67 68 66 73 Third unit 82 86 82 91 Fourth unit 107 108 107 111 Refer to Table 4 . If the government charged a fee of $84 per unit of pollution, how many units of pollution would the firms eliminate altogether?

Suppose the government taxes 25 percent of the first $60,000 of income and 40 percent of all income above $60,000. For a person earning $200,000, the marginal tax rate is

All of these are correct

Refer to Figure 2. The tax causes consumer surplus to decrease by the area

Refer to Figure 2. The government collects tax revenue that is the area

B+D

Table 1Consider the following table of long-run total cost for four different firms: Quantity 1 2 3 4 5 6 7 Firm 1 $180 $350 $510 $660 $800 $930 $1,050 Firm 2 $120 $250 $390 $540 $700 $870 $1,050 Firm 3 $150 $300 $450 $600 $750 $900 $1,050 Firm 4 $210 $340 $490 $660 $850 $1,060 $1,290 Refer to Table 1.Which firm has economies of scale over the entire range of output?

Firm 3 Only

Refer to Figure 5. From the figure it is apparent that

Guatemala has a comparative advantage in producing coffee, relative to the rest of the world.

Refer to Figure 1. Suppose the government imposes a tax of P' - P'''. Total surplus after the tax is measured by the area

I+J+K+L+M+Y.

Refer to Table 1. Which firm has diseconomies of scale over the entire range of output?

Table 2 Only

The Ogallala aquifer is a large underground pool of fresh water under several western states in the United States. Any farmer with land above the aquifer can at present pump water out of it. Which of the following statements about the aquifer is correct?

The aquifer is a common resource which will be overused if no one owns it.

A city street is

a common resource when it is congested, but it is a public good when it is not congested.

A taxpayer faces the following tax rates on her income: 20 percent of the first $40,000 of her income; 30 percent of all her income above $40,000. The taxpayer faces

an average tax rate of 22.0 percent when her income is $50,000.

If a consumer places a value of $15 on a particular good and if the price of the good is $17, then the

consumer does not purchase the good.

Both tariffs and import quotas

decrease the quantity of imports and raise the domestic price of the good

Refer to Figure 3. If this market is currently producing at Q4, then total economic well-being would be maximized if output

decreased to Q2.

Refer to Figure 5. When trade in coffee is allowed, consumer surplus in Guatemala

decreases by the area B + D.

Refer to Figure 5. With trade, Guatemala will

export 22 units of coffee.

In many cases selling pollution permits is a better method for reducing pollution than imposing a corrective tax because

it is hard to estimate the market demand curve and thus charge the "right" corrective tax.

If the government were to impose a tax that assigned everyone the same tax liability, it would be

lump-sum tax

Refer to Table 5. Suppose the government is considering levying a tax in one or more of the markets described in the table. Which of the markets will allow the government to minimize the deadweight loss(es) from the tax?

markets B and D only

The particular price that results in quantity supplied being equal to quantity demanded is the best price because it
