![3) Jack's Labor Demand Problem
Jack hires craftswomen like Jane to help produce widgets. Jack acts like a price-taker in
the widget (output) market. His production function is as follows
= ZOL-L?
Q = F(K,L)=4(KxL) – Ľ²
TT-BrQ-WL-VK
In the short-run, Jack's capital is fixed at 5 units (K = 5). In the long-run, he cán acquire
more capital by paying r for each unit of additionalcapital. Given a price of p for his ŏll=O
widgets, Jack's short-run profit maximization problem can be written as
max 7=PxF(K,L)-[wL+rK]
= P x [ 4 (5 × L) – L2 ] - [ wL + 5r]
Assume for now that Jack is a price-taker in the labor market as well. The going wage is
w= $10, price for widgets P = 5, and factor price for capitál r= 15
(3a) What is Jack's short-run marginal product of labor? What is Jack's short-run
marginal revenue?
(3b) What is Jack's short-run marginal revenue product of labor?
(3c) Given that Jack is a price-taker in the labor market, how much labor would Jack buy
given the prevailing prices. How much widgets does Jack make? What is Jack's profit?
OPTIONAL: Although Jack acts as a price taker, is the widget market competitive for
this example? Look at Jack's profit. At the going price of widgets, is P = MC?
(3d) Suppose that Jack is a monopolist in the widget market and faces the following
inverse demand for widgets: P(Q) = 30 – 0.25 Q. What is Jack’s marginal revenue now?
marginal revenue product for labor?
(3e) Sketch Jack’s labor demand curve as a price-taker and as a monopolist in the widget
market.
(3f) As a monopolist, does Jack buy more or less labor? Briefly explain why. No need to
solve for the profit maximizing quantity of labor. But you can if you want (algebraically
tedious).
(3g) Re-do (3c) assuming that K=4 and K = 6.
(3h) Based on (3c) and (3g) and the prevailing prices, would Jack rather use more or less
capital given the choice? In the medium/long run, what would we expect to happen to the
factor price of capital (r), assuming w and p remain unchanged?
(3i) Suppose Jack is a monopsonist in the labor market and faced a labor supply curve
similar to the labor supply curve you derived for Jane (Question 2). Would Jack buy more
or less labor as a monopsonist ? Briefly explain why.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1e99b076-d7ba-4bd3-9136-e67d6db3098b%2Fd98d3bb1-10e0-470c-bb54-5c2033684bb3%2F43t5y2_processed.jpeg&w=3840&q=75)
