7.1 COMPETITION & MARKET STRUCTURES
Four Types of Structures
I. Perfect Competitiona. large # of buyers & sellers exchange identical products.
5 conditions:
1. large # of buyers and sellers
2. Identical products
3. buyers & sellers act independently
4. they are well informed
5. are free to enter, conduct or get out
of business
b. Supply & Demand set equilibrium price.
c. Each firm sets level of output to maximize its profits
d. Imperfect competition= market structure that lacks one or more of the above
II. Monopolistic Competition
a. Meets all the previous conditions EXCEPT identical products
b. Uses product differentiation (real or imagined differences)
c. Uses non-price competition:
use of advertising
giveaways
or promotional campaigns to differentiate products
III. Oligopolya. very few sellers dominate market
b. act interdependently by lowering & raising prices
c. May formally agree to set prices, called COLLUSION, (illegal in US)
1. price fixing- agree to a charge above
the market price
2. dividing up market for guaranteed sales
3. agree to create shortage to raise prices
EX: OPEC cut production in 1970s- gas prices rose dramatically
d. can engage in price wars, for short period
e. final prices are likely higher than monopolistic & perfect
competition

3. Technological monopoly- based on ownership of method, process or
advancement.
