2010 Free Response Question (Short) – Factor Markets
The John Lamb Company, a profit-maximizing firm producing widgets, is in a perfectly competitive
widget market. Assume John Lamb employs a fixed number of employees and rents a machine for a
variable number of hours from a perfectly competitive market.
(a) Using correctly labeled side-by-side graphs of the factor market for machines and the John Lamb
Company, show each of the following.
(i) The equilibrium rental price of machines in the factor market, labeled as PR
(ii) John Lamb’s equilibrium rental quantity of machines, labeled as QL
(b) Assume that the popularity of widgets declines, decreasing the demand for widgets. What will happen
to each of the following?
(i) Marginal product curve for machine-hours
(ii) Marginal revenue product curve for machine-hours. Explain.
(c) John Lamb is employing the cost-minimizing combination of inputs. The marginal product of labor is
28 widgets per worker hour and the wage rate is $14 per hour. The marginal product of the machine is
60 widgets per machine-hour. What is the hourly rental price of a machine?

2007 Free Response Question (Short) – Factor Markets
Assume that HZRad Company produces clock radios as shown in the short-run production function table
shown below. HZRad can sell all of the clock radios it can produce at a market price of $20 each and can
hire all the unskilled labor it wants at a rate of $90 per day per worker. Assume also that labor is the only
variable input.

(a) Using the specific information above, draw a correctly labeled graph of HZRad’s current supply curve
for unskilled labor.
(b) What is HZRad’s profit-maximizing output level? Explain.
(c) Suppose that HZRad is the first company that uses a new technology that increases the productivity of
its unskilled workers.
(i) How will the new technology affect the quantity of unskilled labor that HZRad hires? Explain.
(ii) How will the new technology affect the wage paid to HZRad’s unskilled workers?

2006B Free Response Question (Short) – Factor Markets
Pride Textiles produces and sells towels in a perfectly competitive market. Pride Textiles hires its workers
in a perfectly competitive labor market. Assume that the market wage rate for workers is $80 per day.
(a) State the conditions necessary for hiring the profit-maximizing amount of labor.
(b) At the profit maximizing level of output, suppose that the marginal product of the last
worker hired is 20 towels per day. Calculate the price of a towel.
(c) Draw a correctly labeled graph of the labor supply and demand curves for Pride Textiles,
and show the equilibrium amount of labor hired.
(d) Given your answer to part (b), if the price of a towel increases, explain how Pride’s
profit-maximizing quantity of labor will be affected.

2003 Free Response Question (Short) – Factor Markets
Assume that Company XYZ is a profit-maximizing firm that hires labor in a perfectly competitive labor
market and sells its product in a perfectly competitive output market.
(a) Define the marginal revenue product of labor.
(b) Using correctly labeled side-by-side graphs, show each of the following.
(i) The equilibrium wage in the labor market
(ii) The labor supply curve the firm faces
(iii) The number of workers the firm will hire.
(c) Company XYZ develops a new technology that increases its labor productivity. Currently this
technology is not available to any other firm. For Company XYZ, explain how the increased productivity
will affect each of the following.
(i) Wage rates
(ii) Number of workers hired

2011B Free Response Question (Short) – Factor Markets
Woodland is a small town in which everyone works for TreeMart, the local lumber company. TreeMart is
a monopsonist in the labor market and a perfect competitor in the lumber market. In the short run, labor is
the only variable input. The labor market for TreeMart is given in the graph above.
(a) Identify the profit-maximizing quantity of labor for TreeMart.
(b) Identify the wage rate TreeMart pays to hire the profit-maximizing quantity of labor.
(c) Identify the quantity of labor hired in each of the following situations.
(i) TreeMart operates in a competitive labor market.
(ii) The government imposes a minimum wage of $12.5. Explain.
If you’re having trouble with this last question (as I was), follow these steps:
1. What is the marginal factor cost for each worker up to 150 workers if the minimum wage is $12.50?
2. Now, to hire more than 150 workers, they have to increase the wage rate for all workers (according to
the labor supply curve, only 150 workers will work for $12.50.) Once they get past 150 workers then,
MFC is greater than wage rate, and lies on the MFC curve on the diagram.
