businesses toward the normal profits and price taking of perfect competition.
o Only seller of product or service; no close substitutes available.
o Demand curve is steep and inelastic.
Market Power:
o Busiesses’ aility to set pries.

o Monopoly with maximum power to set prices.
Moopoly’s Ielastic Dead (Fig. 8.1):
Businesses can set any price, but cannot force consumers to buy.
o Even monopoly price must live by law of demand.

Market Structure:
o Characteristics affecting competition and pricing power.
Available substitutes.
Number of competitors.
Barriers to entry of new competitors.
o Broader definition of market = more substitutes and competitors, more elastic demand, less
pricing power.
o Narrower definition of market = fewer substitutes and competitors, more inelastic demand,
more pricing power.
Product Differentiation:
o Attempt to distinguish product or service from those of competitors.
Reduces competition and substitutes, increase pricing power.
Can be actual differences or perceived differences.
