output level
which of the following statements has to be true in a perfectly competitive market?
a firm's marginal revenue equals price
In the short run, if the product price of a perfectly competitive firm is less than the minimus average variable cost, the firm will
lose more by continuing to produce than by shutting down
Whic of the following statements is true of perfectly competitive firms in long-run equilibrium?
average total cost is at a minimum

In most cases, the supply curve for a perfectly competitive industry can be described as which of the following
more elastic in the long run than in the short run
A farmer produces peppers in a perfectly competitve market. If the price falls, in the short run, the farmer should
continue to produce only if the new price covers average variable costs.
Whic of the following is ture if a perfectly competitve market is in long-run equilibrium?
marginal revenue is equal to average total cost
Given the cost and demand schedules depicted above, if the firm increase output from q1 to q2, it would
experience a decline in profits
