Ā
Despite the fact that few firms sell identical products in markets where there are no barriers toā entry, economists believe that the model of perfect competition is important because
Ā
Ā
A.
economists prefer studying theoretical markets instead of actual markets.
Ā
B.
all markets eventually become perfectly competitive.
Ā
C.
it is a
benchmarkāa
market with the maximum possible
competitionāthat
economists use to evaluate actual markets that are not perfectly competitive.
Ā
D.
this is the type of market that our business laws protect and promote.
Suppose the competitive market price is $60, and a competitive firmās total costs = q^2 - 6q + 990 and marginal cost = 2q - 6.
Ā
a. Solve for the profit-maximizing (or loss minimizing) quantity (q*).
Ā
b. What is the market equilibrium price?
Ā
c. Should the competitive firm produce q*? Explain why using one of the four key questions and solutions.
Ā
d. Does the competitive firm make a profit? Explain why using one of the four key questions and solutions.
e. How much profit (or loss) does the competitive firm make?
Consider a kettle firm A in a perfectly competitive market. Table 1 shows the quantity
produced per hour (Q) and the total cost (TC) in the short run.
