Table 8.2

Refer to Table 8.2, which gives a firm's production function. Assume that all non labor inputs are fixed. Diminishing returns set in with the addition of the:

−

A. sixth worker. B. third worker. C. fourth worker. D. fifth worker.

In the short run, the marginal cost of the first unit of output is $20, the marginal cost of producing the second unit of output is $16, and the marginal cost of producing the third unit of output is $12. The firm's total variable cost of producing three units of output is:

A. $12. B. $20. C. $48. D. $16.

In the short run, the marginal cost of the first unit of output is $40, the average variable cost of producing three units of output is $32, and the marginal cost of producing the second unit of output is $32. What is the marginal cost of producing the third unit of output?

A. $40 B. $32 C. $96 D. $24

The explicit and implicit costs for Reliance Publishing are shown below:

Cost Wages paid to employees $ ,000114 Funds spent on equipment $ ,000110

Raw materials $ ,00053 Wages foregone in another job $ ,000106

The explicit costs for Reliance Publishing are $ . (Enter your response as a whole number.)

The accounting cost for Reliance is

A. $ .383,000 B. $ ,000.114 C. $ .277,000 D. $ .224,000

Compute the Cost. Edward the entrepreneur takes 2 hours to cut a lawn and he cuts lawns per year. He uses solar-powered equipment (truck and mower) that will last forever and could be sold at any time for $20,000. Edward could earn $ per hour as a pedicurist. The interest rate is 10 percent.

a. Given his current output level, his marginal cost is $ (enter your response to the nearest dollar) and his average cost is $ (enter your response to the nearest dollar).

b. Suppose he decides to reduce the number of lawns cut by half, to per year. His new marginal cost is $ (enter your response to the nearest dollar) and his new average cost is $ (enter your response to the nearest dollar).

Constant Marginal Cost. Consider a firm operating in the long run with an indivisible input that has a cost of $ . The marginal cost of production is constant at $ per unit.

Carefully follow the instructions above, and only draw the required objects.

The long-run average cost drops from $ for the first unit to $ for the unit. (Enter your responses rounded to the nearest penny.)
