why competitive firms stay in business if they make zero profit?
You read in a business magazine that farmers are reaping high profits. With the theory of perfect competition in mind, what do you expect to happen over time (in the long run) to each of the following?
The equilibrium output in agricultural markets
based on what happens to the price given the change in supply, what do you think will happen to the equilibrium quantity? Will it remain the same, increase or decrease?
George Stigler, "Perfect Competition, Historically Contemplated," Journal of Political Economy,Vol. 55, No. 1, (February 1957), pp. 1-17.
Despite the fact that few firms sell identical products in markets where there are no barriers to entry, economists believe that the model of perfect competition is important because
A.
economists prefer studying theoretical markets instead of actual markets.
B.
all markets eventually become perfectly competitive.
C.
it is a
benchmark—a
market with the maximum possible
competition—that
economists use to evaluate actual markets that are not perfectly competitive.
D.
this is the type of market that our business laws protect and promote.

- We expect that firms in perfectly competitive markets can earn higher economic profits in the short run but will only earn normal profit in the long run. Why do we expect perfectly competitive firms to be unable to earn high economic profit in the long run? The inability of perfectly competitive firms to earn high economic profit in the long run is dependent on there being low barriers to entry in perfectly competitive markets. Explain why this is the case. Why do firms remain in business if they cannot earn economic profit?arrow_forwardYou read in a business magazine that farmers are reaping high profits.

- Perfect competition is an extremely rare type of market in the real world. This is because the conditions necessary for perfect competition are difficult to meet. Write about an example of perfect competition (or at least a market that is very close to perfect competition). Find an example of a market that seems to be perfectly competitive. Explain how your example satisfies the four conditions necessary for perfect competition. Do sellers in the market you’ve described brand themselves to consumers? Does this support the idea that this market is perfectly competitive? Explain. Do different sellers in the market you’ve described charge different prices for their product? Does your answer support the idea that this market is perfectly competitive? Explain. Does it seem as if the example you mentioned is allocatively efficient? In other words, does the market produce enough of this good (or does it produce too much or too little)? Explain.arrow_forwardIn a long-run equilibrium in a perfectly competitive market, firms earn positive economic profits.
