Document Summary

The following four conditions are characteristics of markets that are perfectly competitive: all firms sell the same standardized product. Although this condition is almost never literally satisfied, it holds as a rough approximation for many markets. Thus, the markets for concrete building blocks of a given size, or for apples of a given variety, may be described in this way. This condition implies that if a potential seller identifies a profitable business opportunity in a market, he or she will be able to obtain the labor, capital, and other productive resources necessary to enter that market. By the same token, sellers who are dissatisfied with the opportunities they confront in a given market are free to leave that market and employ their resources elsewhere: buyers and sellers are well informed. This condition implies that buyers and sellers are aware of the relevant opportunities available to them.

1. Characteristics of competitive markets

The model of competitive markets relies on these three core assumptions:

1.	There must be many buyers and sellers a few players can't dominate the market.
2.	Firms must produce identical products buyers must regard all sellers' products as equivalent.
3.	Firms and resources must be fully mobile, allowing free entry into and exit from the industry.

The first two conditions imply that all consumers and firms are price takers. While the third is not necessary for price-taking behavior, assume for this problem that a market cannot maintain competition in the long run without free entry.

Identify whether or not each of the following scenarios describes a competitive market, along with the correct explanation of why or why not.

Scenario	Competitive?

c. shows that the individual firm can increase sales by lowering the price of output.

d. has a marginal revenue that is always decreasing.

b. a price taker and cannot affect the market price of wheat.

c. always able to price produce above the competition and earn a larger profit.

d. never able to determine any prices he charges for anything, such as soybeans

3. All of the following are true regarding perfectly competitive price determination EXCEPT

Select one:
