Explanation of Solution

The marginal product is the additional output produced due to the employment of an additional unit of labor. The marginal product can be obtained using Equation 1 as given below:

Marginal product= Total outputPresentTotal outputPreviousUnits of laborPresentUnits of laborPrevious (1)

Substitute the respective values in Equation (1) to calculate the marginal product.

Marginal product=20010=201=20

The marginal product of first worker is 20.

Total revenue can be calculated using Equation (2) as follows:

Total revenue=Total output×Price (2)

Substitute the respective values in Equation (2) to calculate the total revenue.

Total revenue=20×12=240

The total revenue from one worker is $240.

When the price of the soccer ball is $12 per ball, the marginal revenue product can be calculated using Equation (3) as follows:

Marginal revenue product=Marginal product×Price (3)

Substitute the respective values in Equation (3) to calculate the marginal revenue product.

Marginal revenue product=20×12=240

The marginal revenue product of first labor is $240.

Table 1 shows the values of marginal product, total revenue, and marginal revenue product, which are obtained using Equations (1), (2), and (3).

Economics Concept Introduction

Marginal product: Marginal product is defined as the additional output produced by increasing the input factor by one unit.

Marginal revenue product: Marginal revenue product is defined as the additional revenue earned by a firm using one additional unit of an input.

Total revenue: Total revenue is defined as the total income earned from the sale of output produced.

Explanation of Solution

Substitute the respective values in Equation (2) to calculate the total revenue.

Total revenue4=140×12=1,680

The total revenue from four workers is $1,680.

Substitute the respective values in Equation (2) to calculate the total revenue.

Total revenue5=180×12=2,160

The total revenue from four workers is $2,160.

The marginal revenue product can be calculated using Equation (4) as follows:

Marginal revenue product=Total revenuePresentTotal revenuePreviousLaborPresentLaborPrevious (4)

Substitute the respective values in Equation (4) to calculate the marginal revenue product.

Marginal revenue product=2,1601,68054=480

The marginal revenue product of fifth worker is $480.

Calculation of marginal revenue product using marginal product.

Substitute the respective values in Equation (4) to calculate the marginal revenue product.

Marginal revenue product=40×12=480

The marginal revenue product of fifth worker is $480.

Thus, it is verified that marginal revenue product can be calculated using both methods.

Explanation of Solution

The firm should hire workers as long as the marginal revenue product of labor is greater than the wage rate. If the firm continues operation, at wage rate equal to $320, the firm should employ 7 workers. This is because the marginal revenue product of the 7th worker is $336, and when the 8th laborer is employed, the marginal revenue product of labor falls to $216.

Explanation of Solution

When the wage rate increases to $400, the number of workers to be hired reduces to 5. The marginal revenue product of the 5th laborer is $480, which is greater than the wage rate. When the 6th worker is employed, the marginal revenue product falls to $360, which is less than wage rate.

Explanation of Solution

When the firm uses new production technology, the marginal product of labor and the marginal revenue product of labor by 50 percent at each worker. When the wage rate is $400, the firm should hire seven workers. The marginal revenue product of the 7th worker is $504, which is higher than the wage rate.

3. Consider a single firm that manufactures chemicals and generates pollution through its emissions E. Researchers have estimated the MDF and MAC curves for the emissions to be the following: MDF = 4E and MAC = 125 – E Policymakers have decided to implement an emissions tax to control pollution. They are aware that a constant per-unit tax of $100 is an efficient policy. Yet they are also aware that this policy is not politically feasible because of the large tax burden it places on the firm. As a result, policymakers propose a two- part tax: a per unit tax of $75 for the first 15 units of emissions an increase in the per unit tax to $100 for all further units of emissions With an emissions tax, what is the general condition that determines how much pollution the regulated party will emit? What is the efficient level of emissions given the above MDF and MAC curves? What are the firm's total tax payments under the constant $100 per-unit tax? What is the firm's total cost of compliance…
2. Answer the following questions as they relate to a fishery: Why is the maximum sustainable yield not necessarily the optimal sustainable yield? Does the same intuition apply to Nathaniel's decision of when to cut his trees? What condition will hold at the equilibrium level of fishing in an open-access fishery? Use a graph to explain your answer, and show the level of fishing effort. Would this same condition hold if there was only one boat in the fishery? If not, what condition will hold, and why is it different? Use the same graph to show the single boat's level of effort. Suppose you are given authority to solve the open-access problem in the fishery. What is the key problem that you must address with your policy?
