Below are sample questions representative of the exercises included on this worksheet and related 12.18 Perfect Competition and Entry Exit skill assessments:

Problem 1Difficulty: Mastery

Use the combined market-and-firm graph to answer the question. Entry shifts market supply right and lowers price until the firm's price line is tangent to ATC. What does the final graph show?

ALong-run equilibrium after entry eliminates economic profit.

BA price floor that keeps price above ATC.

CShort-run shutdown because price is below AVC.

DPersistent monopoly profit after entry is blocked.

Solution & Explanation:Entry increases supply and lowers price. When the final price equals minimum ATC for the representative firm, economic profit is zero and the industry is in long-run equilibrium.

Problem 2Difficulty: Mastery

At the output where P = MC, a competitive firm's price equals ATC and is above AVC. Which long-run prediction is most accurate?

AExit will occur because economic profit is zero.

BShutdown will occur because price is above AVC.

CEntry will occur because price equals ATC.

DThere is no profit-based pressure for firms to enter or exit.

Solution & Explanation:When price equals ATC at the profit-maximizing output, the firm earns zero economic profit. That removes profit-based entry and exit pressure.

Problem 3Difficulty: Mastery

A competitive industry begins with economic losses. After long-run exit, the market contains fewer firms. Which statement best describes the new equilibrium?

APrice is set by the largest remaining firm above marginal cost.

BPrice equals maximum ATC because output has decreased.

CPrice remains below AVC for remaining firms, and losses continue forever.

DPrice equals minimum ATC for remaining firms, and economic profit is zero.

Solution & Explanation:Exit reduces market supply and raises price until remaining firms cover all economic costs. In long-run equilibrium, P = minimum ATC and economic profit is zero.
