9) Economic profit is equal to the difference between: 9)

TRUE/FALSE. Write 'T' if the statement is true and 'F' if the statement is false.

10) At the point where a firm incurs diminishing marginal returns, total product will begin to decline.

MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question.

11) In the context of a production function, the remote order takers in the fast food industry would be classified as:

A) a fixed input.

B) a marginal input.

C) an inframarginal input.

D) a variable input.

MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question.

16) A labor-intensive method of production is one that:
A) combines a small but sophisticated labor force with a large amount of capital.

B) requires employees to work harder than they would in other occupations.
C) relies on large quantities of labor and smaller quantities of capital equipment. D) relies exclusively on labor.

MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question.

17) Assume a firm produces 500 units of a good by using two inputs, capital and labor, whose per unit prices are $10 and $4. Assume also that the marginal physical product of the last unit of capital is 30 and the marginal physical product of the last unit of labor is 10. To minimize costs this firm should employ:

A) more labor and less capital. B) more capital and less labor.
C) the existing combination of resources. D) both more labor and more capital.

TRUE/FALSE. Write 'T' if the statement is true and 'F' if the statement is false.

18) All else constant, a decrease in the per unit price of labor would create an incentive for a firm manager to substitute labor for capital in the firm's production process.

MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question.

19) All else constant, as the price of petroleum increases relative to the prices of other inputs to the production process, in their effort to minimize their total costs of production, we can expect to see firms employ:

A) the same amount of petroleum since there are no substitutes for petroleum. B) less petroleum and more of the other inputs to production.
C) less of each of the inputs of production.

D) more petroleum and less of the other inputs to production.
