The following table depicts the output of a firm that manufactures computer printers. The printers sell for $\$100$each.

Labor Input (workers per week)	Total Output ( printers per week)
10	200
11	218
12	234
13	248
14	260
15	270
16	278

Calculate the marginal product and marginal revenue product at each input level above 10 units.

Why would increased use of robotic sewing machines on the part of a clothing manufacturer cause the marginal product derived from utilization of these machines to decline?

Since the beginning of this century, there has been a significant increase in the price of corn-based ethanol.

a. A key input in the production of com-based ethanol is com. Use an appropriate diagram to explain what has likely occurred in the market for corn if the supply curve has not shifted.

b. In light of your answer to part (a), explain why many hog farmers, who in the past used corn as the main feed input in hog production, have switched to cookies, licorice, cheese curls, candy bars, and other human snack foods instead of corn as food for their hogs.

Refer back to your answers to Problem 28-1 in answering the following questions.

a. What is the maximum wage the firm will be willing to pay if it hires 15 workers?

b. The weekly wage paid by computer printer manufacturers in a perfectly competitive market is $\$1200$. How many workers will the profit-maximizing employer hire?

c. Suppose that there is an increase in the demand for printed digital photos. Explain the likely effects on marginal revenue product, marginal factor cost, and the number of workers hired by the firm?

Identify the key factors influencing the elasticity of demand for inputs.

The following table depicts the output of a firm that manufactures computer printers. The printers sell for $\$100$ each.

Calculate the marginal product and marginal revenue product at each input level above 10 units.
