Question 1

-Refer to the table above. If A = 5, B = 7.5, and C = 20, which of the following is true?

Accepted Answer

The firm should buy more of Input 3 because its marginal product per dollar spent (C = 20) is higher compared to Inputs 1 (A = 5) and 2 (B = 7.5), indicating higher efficiency.

Question 2

If the cost of capital is $15 per hour, the wage paid to employees is $25 per hour, the marginal product of capital is 90 units per hour, and the marginal product of labor is 100 units per hour, to minimize its costs, the firm should _________ .

Accepted Answer

To minimize costs, the firm should use the inputs until the marginal productivity (the additional output produced by using an additional unit of input) of labor and capital equals their respective prices.

In this case, the marginal product of labor (MPL) is greater than the wage rate (W = $25/hour), so the firm should hire more labor until MPL = W. This implies that the firm should use more labor and less capital.

On the other hand, the marginal product of capital (MPK) is less than the cost of capital (r = $15/hour), so the firm should use less capital until MPK = r. This implies that the firm should use less capital and more labor.

Therefore, the best choice is to decrease the amount of labor used and increase the amount of capital used, which is answer choice C.

Question 3

If the cost of capital is $1,000 per hour, the wage paid to employees is $50 per hour, the marginal product of capital is 800 units per hour, and the marginal product of labor is 40 units per hour, to minimize its costs, the firm should _ .

Accepted Answer

The answer of If the cost of capital is $1,000...

Question 4

If the cost of capital is $100 per hour, the wage paid to employees is $20 per hour, the marginal product of capital is 10 units per hour; and the marginal product of labor is 2 units per hour, the firm is minimizing costs.

Accepted Answer

The firm is minimizing costs because the marginal product of capital per dollar spent on capital is equal to the marginal product of labor per dollar spent on labor.

Question 5

If the cost of capital is $80 per hour, the wage paid to employees is $15 per hour, the marginal product of capital is 24 units per hour; and the marginal product of labor is 3 units per hour, to minimize its costs, the firm should increase the total amount of labor used and decrease the amount of capital used.

Accepted Answer

To minimize costs, the firm should increase the ratio of capital to labor, as the marginal product of capital is higher than the marginal product of labor. This means using more capital and less labor.

Question 6

-Refer to the table above. If A = 5, B = 7.5, and C = 10, which of the following is true?

Accepted Answer

Without the table, it's impossible to calculate the exact cost-minimization strategy. However, the correct answer is based on the assumption that the given values of A, B, and C already represent the cost-minimizing quantities of inputs.

Question 7

If the cost of capital is $100 per hour, the wage paid to employees is $20 per hour, the marginal product of capital is 10 units per hour; and the marginal product of labor is 5 units per hour, the firm is minimizing costs.

Accepted Answer

In order to minimize costs, the firm should allocate its resources in such a way that the marginal product per dollar spent is equal for all factors of production. In this case, the marginal product of capital is twice that of labor, so the firm should hire more capital and less labor to achieve cost minimization. Therefore, the firm is not currently minimizing costs.

Question 9

Question 10

-Refer to the table above. If A = 6 and B = 8, which of the following is true?

Accepted Answer

Without the table, it's impossible to analyze the specific input-output relationships or cost structures. However, the correct answer is chosen based on the assumption that if a firm is operating where A = 6 and B = 8, and these values represent optimal conditions given by the question, then the firm is minimizing costs under those conditions.

Question 11

To minimize costs, in the short- run, managers need to focus on minimizing the cost of the fixed inputs.

Accepted Answer

To minimize costs in the short-run, managers need to focus on minimizing the cost of variable inputs as fixed inputs cannot be adjusted in the short-run.

Question 12

If the cost of capital is $100 per hour, the wage paid to employees is $20 per hour, the marginal product of capital is 10 units per hour; and the marginal product of labor is 4 units per hour, to minimize its costs, the firm should increase the total amount of labor used and decrease the amount of capital used.

Accepted Answer

Given the information, the marginal cost of producing one unit using capital is $10 per unit ($100/10 units), and the marginal cost of producing one unit using labor is $5 per unit ($20/4 units). Since labor is cheaper per unit of output, to minimize costs, the firm should use more labor and less capital.

Question 15

If the cost of capital is $90 per hour, the wage paid to employees is $45 per hour, the marginal product of capital is 180 units per hour, and the marginal product of labor is 90 units per hour, to minimize its costs, the firm should _________ .

Accepted Answer

To minimize costs, a firm should equate the ratio of the marginal product to the price for all inputs. Here, the marginal product per dollar for both labor and capital is 2 (90 units/$45 for labor and 180 units/$90 for capital), indicating that the firm is already minimizing costs by using the current amounts of labor and capital.

Question 16

-Refer to the table above. If A = 6 and B = 9, for which value of C is the firm minimizing costs?

Accepted Answer

The firm minimizes costs when the marginal product per dollar spent is equal for all inputs. If A = 6 and B = 9, the value of C that balances the equation for cost minimization is 12.

Question 17

-Refer to the table above. If A = 10, B = 15, and C = 20, which of the following is true?

Accepted Answer

Without the table, it's impossible to analyze the specific values and make calculations regarding inputs and costs. However, the correct answer is chosen based on the assumption that the firm is already minimizing costs given the values of A, B, and C provided.

Question 18

-Refer to the table above. If A = 10, B = 30, and C = 20, which of the following is true?

Accepted Answer

Given the values for A, B, and C, the firm should adjust its input mix to buy more of Input 2 and less of Inputs 1 and 3 to minimize costs or maximize productivity based on the given prices or productivity rates. Without the specific table data, the general principle is to allocate resources where they yield the most efficient return.
