Consider a small landscaping company run by Mr. Viemeister. He is considering increasing his firm’s capacity. If he adds one more worker, the firm’s total monthly revenue will increase from $50,000 to $58,000. If he adds one more tractor, monthly revenue will increase from $50,000 to $62,000. Each additional worker costs $4,000 per month, while an additional tractor would also cost $4,000 per month. LO16.5 a. What is the marginal product of labor? The marginal product of capital? b. What is the ratio of the marginal product of labor to the price of labor (MPL/PL)? What is the ratio of the marginal product of capital to the price of capital (MPK/PK)? c. Is the firm using the least-costly combination of inputs? d. Does adding an additional worker or adding an additional tractor yield a larger increase in total revenue for each dollar spent?
Suppose you have three producers of oil A, B, and C, with extractions
costs of $8, $10, and $12 per barrel of oil. Assume there are no
additional user costs. Assume that each well can produce 100 barrels of
oil per day. How many barrels of oil will be produced if the market price
of oil is $10 per barrel ?

Suppose that a car dealership wishes to see if efficiency wages will help improve its salespeople’s productivity. Currently, each salesperson sells an average of one car per day while being paid $20 per hour for an eight-hour day. LO17.8 What is the current labor cost per car sold? Suppose that when the dealer raises the price of labor to $30 per hour the average number of cars sold by a salesperson increases to two per day. What is now the labor cost per car sold? By how much is it higher or lower than it was before? Has the efficiency of labor expenditures by the firm (cars sold per dollar of wages paid to salespeople) increased or decreased? Suppose that if the wage is raised a second time to $40 per hour the number of cars sold rises to an average of 2.5 per day. What is now the labor cost per car sold? If the firm’s goal is to maximize the efficiency of its labor expenditures, which of the three hourly salary rates should it use: $20 per hour, $30 per hour, or $40 per hour?…arrow_forward
