Monopolistic competition is a market structure with many sellers producing differentiated products. In the short run, each firm acts like a monopoly and can earn profits by producing where marginal revenue equals marginal cost. In the long run, free entry and exit causes profits to disappear as new firms enter and demand curves shift left, leading to a zero profit equilibrium. While monopolistic competition provides variety for consumers through differentiated products, it is inefficient compared to perfect competition due to excess capacity and price above marginal cost.

A market can be defined as a group of firms willing and able to sell a similar product or service to the same potential buyers.
Imperfect competition covers all situations where there is neither pure competition nor pure monopoly.
Perfect competition and pure monopoly are very unlikely to be found in the real world.
In the real world, it is the imperfect competition lying between perfect competition and pure monopoly.
The fundamental distinguishing characteristic of imperfect competition is that average revenue curve slopes downwards throughout its length, but it slopes downwards at different rates in different categories of imperfect competition.
Monopoly refers to the market situation where there is a
Single seller selling a product which has no close substitutes.
Monopolies are characterized by a lack of economic competition to produce the good or service, a lack of viable substitute goods, and the existence of a high monopoly price well above the firm's marginal cost that leads to a high monopoly profit
The word “oligopoly” comes from the Greek “oligos” meaning "little or small” and “polein” meaning “to sell.” When “oligos” is used in the plural, it means “few” ,few firms or few sellers.
DEFINATION:
Oligopoly is that form of market where there are few firms and there is natural interdependence among the firms regarding price and output policy.

3. Market Structures Between Pure Competition
and Pure Monopoly
• Pure competition and pure monopoly are two extreme market
structures.
• Most markets in real world are somehow between them.
• Several firms in market
• Differentiated products
• Strategic behavior
13-3
4. Monopolistic Competition and Oligpoly
• Two market structures considered
• Monopolistic competition (This chapter)
• Product differentiation
• Relatively large number of sellers
• Oligopoly (Next chapter)
• Few firms interact each others
• Many different oligopoly models for different behavior assumptions
13-4
5. Industry Concentration
• Two measurements of Industry concentration
• 4-firm concentration ratio (CR)
• Percentage of sales by 4 largest firms
• Herfindahl index (HI)
• Sum of squared market shares
HI = (%S1)2 + (%S2)2 + (%S3)2 + …. + (%Sn)2

7. Monopolistic Competition
• Monopolistic competition
• Relatively large number of sellers
• Product differentiation
• Easy entry and exit
• Nonprice competition like advertising
LO13.1 13-7
8. Characteristics of Monopolistically Competitive firm
• Each firm has small share of market
• Production differentiation
• Brand loyalty
• Monopoly power within own market
• Competitor produce similar substitutes
• Demand is downward-sloping, but highly elastic
• Demand shifts when competitors introduce identical or near identical
products
13-8
9. Price and Output in Monopolistic Competition
• Profit-maximizing monopolistically competitive firm
produces at MR = MC
• In short run it acts like monopoly
• Earn an economic profit
• In Long run competitors enter the market and introduce
near-identical products
• Demand decreases
• Earn normal profit
LO13.2 13-9
10. A Monopolistically Competitive Firm: Short Run Profits
• In short run, a monopolistically
competitive firm has monopoly power
in own brand market.
• Market demand is downward sloping
because of close substitutes: When a
price increases, consumers will switch
brands.
• To maximize total profits, a firm
chooses quantity where MR = MC.
• If price is higher than ATC, a firm will
make profit in short run.

12. A Monopolistically Competitive Firm: Long Run Equilibrium
• If a firm makes profits in short run, in
long run other firms will introduce
similar products. Then, the demand for
own brand product will decrease
(demand curve will shift to left).
• If a firm makes losses in short run, in
long run some firms which make similar
products will exit. Then, the demand
for own band product will increase
(demand curve will shift to right).
• Entry and exit continue until
monopolistically competitive firms
make zero economic profits in long run.

13. Monopolistic Competition and Efficiency
• Monopolistic competition is inefficient in long run
• Productive inefficiency because P > min ATC
• Allocative inefficiency because P > MC
• Excess capacity: Firms will produce a quantity for profit-
maximization (at MR = MC), which is less than the quantity
at minimum ATC.
LO13.3 13-13
14. The Inefficiency of Monopolistic Competition
• ATC is minimum at b when Q4 units are produced.
• Firm chooses profit maximization at d and produces Q3 units.

15. Product Variety
• The firm constantly manages price, product, and advertising
• Better product differentiation
• Better advertising
• The consumer benefits by greater array of choices and
better products
• Types and styles
• Brands and quality
LO13.4 13-15
16. Last Word: Higher Wages, More McRestaurants
• Higher minimum wage favors big hamburger chains.
• Big chain restaurants are capital intensive, so an
increase in the minimum wage doesn’t affect them
much.
• Mom-and-pop restaurants are labor intensive, so an
increase in the minimum wage can put them out of
business.
• Politicians and the public need to be aware of the
consequences of policy.
