• Goods are NOT identical.• Firms seek to capture a piece of the market by making unique goods.
• Since these products have substitutes, firms use NON-PRICE Competition.

Monopolistic Competition is made up of price makers so MR is less than Demand
In the short-run, it is the same graph as a monopoly making profit
In the long-run, new firms will enter, driving down the DEMAND for firms

Why does DEMAND shift?When short-run profits are made…
–New firms enter.–New firms mean more close
substitutes and less market share for each existing firm.
–Demand for each firm’s product falls.
When short-run losses are made…–Firms exit. –Result is fewer substitutes and larger
market share for remaining firms.–Demand for each firm’s product rises.

Side NoteThe elasticity of demand for a monopolistically competitive firm’s product varies with the number of competitors:
If there are many competitors (and therefore many substitutes), demand for the firm’s product will tend to be more elastic
If there are fewer competitors and substitutes, demand will tend to be less elastic

• Large number of firms and product variation meets society’s needs.
• Nonprice Competition (product differentiation and advertising) may result in sustained profits for some firms.
Ex: Nike might continue to make above normal profit because they are a well-known brand.
