Will a profit-maximizing firm in a competitive market ever produce a positive level of output in the range where the marginal cost is falling? Give an explanation.
You witnessed new firms entering a competitive market. What can you infer for the existing firms in that market?
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.

- According to marginal analysis, a perfectly competitive firm will produce an output level where what is true about its Marginal Revenue and its Marginal Cost?arrow_forwardPerfect 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). 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 the long run, perfectly competitive firms make zero economic profit. If this is the case, why does the firm even bother producing? Why not exit the market completely?arrow_forward
- The market for drones is perfectly competitive. Assume for simplicity that fractions of everything, including number of firms, is possible. We have identical firms, each with a Total Cost curve of TC=862+q^2 and Marginal Cost curve MC=2q. Market demand is Q=856-2P. What is the number of firms in the market in the long run equilibrium?arrow_forwardIf this is the case of a typical firm in a perfectly competitive market, what is most likely to happen?arrow_forwardThe competitive firm isarrow_forward
- The market structure of perfect competition has a lot of ideal qualities–hence the name perfect. For example, perfectly competitive firms are productively efficient, and perfectly competitive markets are allocatively efficient. It is, however, difficult to find many examples of perfectly competition in the real world. Perfect competition is really a benchmark against which we compare other market structures in the real world. How much actual competition occurs in perfectly competitive markets? Some make the claim that there is actually no competition between firms in a perfectly competitive market. Do you agree or disagree with this claim? What is your reasoning?arrow_forwardConsider a firm with TC=1Q^2+8 where 8 is the fixed cost of being in the market (MC=2*1Q). Demand is given by Q_D=30-4P. How many firms will be in the market if the market operates in a perfectly competitive way?arrow_forwardPerfect 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.
