Question

which of the following best describes why a perfectly competitive firm will sometimes continue producing in the short run even if it incurs a loss?
a. if price exceeds average total cost, the loss from covering the fixed costs will be smaller than the loss from covering the variable costs.
b. as long as price exceeds average variable cost, the loss from producing will be smaller than the loss from shutting down, which is equal to the amount of total fixed costs.
c. a perfectly competitive firm should never produce if it incurs a loss because it is unable to influence the market price.
d. short - run losses turn into long - run profits when there is entry into the market.

Explanation:

In perfect competition, a firm's short-run shutdown rule is based on average variable cost (AVC). If price exceeds AVC, producing covers all variable costs and some fixed costs, resulting in a smaller loss than shutting down (where the firm still pays all fixed costs). Option a is incorrect because price exceeding average total cost means profit, not loss. Option c is wrong as firms can produce at a loss in the short run. Option d is incorrect because market entry reduces profits, not turns short-run losses into long-run profits.

Answer:

b. As long as price exceeds average variable cost, the loss from producing will be smaller than the loss from shutting down, which is equal to the amount of total fixed costs.
