Problem 1
Joe Brown’s dairy operates in a perfectly competitive marketplace. Joe’s machinery costs $500 per day and is the only fixed input. His variable costs are comprised of the wages paid to the few workers he employs at the dairy and the grain he feeds to his dairy cows.
The variable cost associated with each level of output is given in the accompanying table.

d. Suppose that the price at which Joe can sell milk is $1.50 per gallon. In the short run, will Joe earn a profit?
e. In the short run, should he produce or shut down?
f. Now suppose that the price at which Joe can milk is $1.00 per gallon. In the short run, will Joe earn a profit?
g. In the short run, should he produce or shut down?
h. Finally, Suppose that the price at which Joe can sell milk is $0.75 per gallon. In the short run, will Joe earn a profit?
i. In the short run, should he produce or shut down?
Problem 2
Suppose that Media Cable is a single-price monopolist in the market for cable in Anywhere, Iowa. Media has five potential customers: Morgan, Larry, Clyda, Janet, and Tom.
Each of these customers are willing to purchase cable service, but only if the price is just equal to, or lower than, his or her willingness to pay. Morgan’s willingness to pay is $130; Larry’s, $100; Clyda’s, $80; Janet’s, $40; and Tom’s, $0.
Media Cable’s marginal cost per cable package is $40. The demand schedule for cable service packages is shown in the accompanying table.

e. How large is the quantity effect?
f. What is the profit maximizing quantity and price for Media Cable?
