A software company in Silicon Valley uses programmers (labor) and computers (capital) to produce apps for mobile devices. The firm estimates that when it comes to labor, MPL = 5 apps per month while PL = $1,000 per month. And when it comes to capital, MPC = 8 apps per month while PC = $1,000 per month. If the company wants to maximize its profits, it should: LO16.5 a. Increase labor while decreasing capital. b. Decrease labor while increasing capital. c. Keep the current amounts of capital and labor just as they are. d. None of the above.
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?
Complete the following labor supply table for a firm hiring labor competitively: LO17.2

- . 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_forwardPROBLEMS 1. Workers are compensated by firms with “benefits” in addition to wages and salaries. The most prominent benefit offered by many firms is health insurance. Suppose that in 2000, workers at one steel plant were paid $20 per hour and in addition received health benefits at the rate of $4 per hour. Also suppose that by 2010 workers at that plant were paid $21 per hour but received $9 in health insurance benefits. LO17.1 By what percentage did total compensation (wages plus benefits) change at this plant from 2000 to 2010? What was the approximate average annual percentage change in total compensation? By what percentage did wages change at this plant from 2000 to 2010? What was the approximate average annual percentage change in wages? If workers value a dollar of health benefits as much as they value a dollar of wages, by what total percentage will they feel that their incomes have risen over this time period? What if they only consider wages when calculating their incomes?…arrow_forwardO1.

- Assume that the productivity of farm labour depends on daily caloric intake, similarly to that depicted in Figure17.4. Using this kind of diagram, compare the efficiency wages that would apply to the following two types of workers: • A landless labourer • A labourer with small plot of land on which he grows staple crops Describe the likely equilibrium unemployment rates and wage rates for landless labourers and small landholders. Judging partially on the basis of this example, what sorts of data and what empirical strategies might you use to see whether nutritional efficiency wages were an important element in the rural labour markets of poor, rural economies?arrow_forwardSuppose that low-skilled workers employed in clearing woodland can each clear one acre per month if each is equipped with a shovel, a machete, and a chainsaw. Clearing one acre brings in $1,000 in revenue. Each worker’s equipment costs the worker’s employer $150 per month to rent and each worker toils 40 hours per week for four weeks each month. LO17.6 Now consider the employer’s total costs. These include the equipment costs as well as a normal profit of $50 per acre. If the firm pays workers the minimum wage of $6.20 per hour, what will the firm’s economic profit or loss be per acre? At what value would the minimum wage have to be set so that the firm would make zero economic profit from employing an additional low-skilled worker to clear woodland?arrow_forward665 Capital (K) 0 10 Labor (L) O $13.30 O $1.95 O $10.19 O $6.34 317 Please refer to the graph above.
