Most Markets…
Do not fit strict assumptions of perfect competition; usually differ in one or more factors
For example: Products may not be completely
identical Entrance into the market may be
costly/difficult

Characteristics/Consequences of Imperfectly Competitive Market
Firms in imperfectly competitive markets are often interdependent, with the actions of one firm greatly affecting business for its competitors

Characteristics/Consequences of Imperfectly Competitive Market
Large firms competing with other large firms often try to avoid direct price competition Uncertain how competitors would
react Joint interest in keeping prices above
the level that would result in perfect competition

Characteristics/Consequences of Imperfectly Competitive Market
In markets dominated by a few large firms, there are some strong pressures supporting price collusion Tacit vs. Explicit in countries like the
U.S. i.e. cell phone companies, cable/Internet
providers Tacit = understood or implied without
being stated Activity 3: Dueling Gas Stations

Characteristics/Consequences of Imperfectly Competitive Market
Both large and small firms in imperfectly competitive markets emphasize nonprice competition Think of all the advertising that stresses
real or imagined differences in the quality of g/s provided to customers!

Non-Price Competition:Real vs. Imagined Differences
1. List strategies each company probably uses for non-price competition.
2. What differences is each company trying to emphasize?

Non-Price Competition:Real vs. Imagined Differences
1. Based on the class results of our blind taste test, did the advertisements promote real or imagined differences?
2. Under which market structure would these companies be categorized?

Pros/Cons
Perfect Competition… Usually lower prices Efficient use of scarce resources Less variety s
Imperfect competition Less competition leads to less output and
higher prices BUT, often offset by large firms able to take
care of economies of scale▪ i.e. “mom & pop shop” vs. Walmart
More variety

The BIG Ideas
Evaluating imperfectly competitive markets involves weighing the costs & benefits
Gov’t should work towards eliminating extreme concentrations of market power & collusive behavior to maintain efficient competition
BUT, policies should stop far short of breaking up large firms just because the market isn’t perfectly competitive.
