a. 2 workers

b. 3 workers

c. 4 workers

d. 5 workers

13.  Refer to Table 1. Assume that MadeFromScratch is a competitive, profit-maximizing firm. If the market price of cupcakes increases from $2.00 to $2.50, how many workers would the firm then hire?

a. 2 workers

b. 3 workers

c. 4 workers

d. 5 workers

14.  Refer to Table 1. Suppose that there is a technological advance that allows MadeFromScratch employees  to

produce more cupcakes than they could before. Because of this change, the firm’s

a. demand for labor shifts right.

b. demand for labor shifts left.

c. supply of labor shifts right.

d. supply of labor shifts left.

15.  Refer to Table 1. Suppose that the firm suffers a loss of some of their technology such as the theft of their industrial mixers. After the theft, MadeFromScratch employees produce fewer cupcakes than they could before because they must mix the cupcake batter by hand rather than using the high-speed mixers.

a. demand for labor shifts right.

b. demand for labor shifts left.

c. supply of labor shifts right.

d. supply of labor shifts left.

16. Which of the following is most likely an inferior good?

1. an antique car

17. A good is an inferior good if the consumer buys more of it when

           a. his income rises.

            b. the price of the good falls.

            c. the price of a substitute good rises.

            d. his income falls.

18. Pepsi and pizza are normal goods. When the price of pizza rises, the substitution effect causes Pepsi to be relatively

            a.more expensive, so the consumer buys more Pepsi.

            b.more expensive, so the consumer buys less Pepsi.

            c.less expensive, so the consumer buys more Pepsi.

            d.less expensive, so the consumer buys less Pepsi.

19.  You can think of an indifference curve as an

            a.equal-cost curve.

            b.equal-marginal-cost curve.

            c.equal-utility curve.

            d.equal-marginal-utility curve.

20.  A Giffen good is one for which the quantity demanded rises as the price rises because the income effect

1. reinforces the substitution effect.
2. reinforces and is greater than the substitution effect.
3. counteracts but is smaller than the substitution effect.
4. counteracts and is greater than the substitution effect.

1. They all relate to macroeconomics.
2. They all relate to monetary economics.
3. They all relate to the theory of consumer choice.
4. They are not related to each other in any way.

22. Just as the theory of the competitive firm provides a more complete understanding of supply, the theory of consumer choice provides a more complete understanding of

            a.demand.

            b.profits.

            c.production possibility frontiers.

            d.supply of a firm’s product.

25.  The theory of consumer choice

            a.underlies the concept of the demand for a particular good.

            b.underlies the concept of the supply of a particular good.

            c.ignores, for the sake of simplicity, the trade-offs that consumers face.

            d.can be applied to many questions about household decisions, but it cannot be                                     applied to questions concerning wages and labor supply.
