• Def: a description of the type of market that a particular business or industry operates in.
• Also know as Market Structure.
4 Types of Models of Competition
1. Perfect competition2. Monopoly 3. Monopolistic competition4. Oligopoly
Perfect Competition
• Def: A market structure in which a large number of firms (businesses) produce the same product

2. Identical products – No difference in items they are exactly the same
Four Conditions for Perfect Competition (cont.)
3. Informed buyers and sellers- buyers know the prices and qualities of goods.
4. Free market entry and exit- Business can enter and exit the market when they want
Types of Businesses
• Farmer’s Market• - Have many buyers and sellers• - Veggies are identical (a carrot is a carrot)• - Buyers can compare prices and quality
(informed)• - Farmers decide to go or not
Are they many perfectly competitive business?
• NO- All 4 conditions must be met.• Ex: Products are rarely identical
Barriers of Entry
• Def- Factors that make it difficult for new firms to enter a market
• Start up costs- costs needed to create and enter a market (rent, machines, labor)
• Technology- (ex: software and pharmaceutical
companies)
Monopoly
• Def: A market dominated by a single seller. • They take advantage of their monopoly power
and charge high prices
• Natural Monopoly- Allowed to exist because the market runs better with just one firm
Ex: Monroe County Water Authority
Government Monopolies
• Patents: Licenses that give inventors exclusive rights to sell their product for a time.
Monopolistic Competition
• Def: Many companies compete in an open market to sell products that are similar but not identical
Four Conditions of Monopolistic Competition
1. Many firms- little start up costs=lots of firms
2. Few artificial barriers to entry- low barriers
3. Slight control over price- can raise prices because products are a little different. 4. Differentiated products-Can distinguish their product from others
What Types of Businesses are Monopolistically Competitive?
• Lots! Most markets exist in this model. • Ex. Soft Drinks- Coke Pepsi, Wegmans, etc• 1. Many firms (choices)• 2. Inexpensive to produce (few barriers)• 3. Coke more expensive (control Price)• 4. Some like Coke more than Pepsi (different
products)
How to get customers?
• Through Nonprice Competition : a way to attract customers through style, service or location but not a lower price.
4 Types
• 1. Characteristics of Goods: Firms distinguish products through size, color taster etc.
• 2. Location of Sale -Convenience stores
• 3. Service Level- Can charge higher price because they offer a higher level of service. Ex McDonalds vs Fancy rest.
• 4. Advertising Image- Advertising creates differences between products
Monopolistic vs Perfect Comp.Perfect Competition Monopolistic
Competition
Prices Lower, firms have no control
Higher, firms have some control
Profit Lower Higher in short term, but must work hard to keep ahead of rivals
Cost and Variety Low costs, no variety (identical products)
Higher costs for differentiation, wide variety
Oligopoly
• Def: A market dominated by a few, large firms
• Ex: Cartels• OPEC (Organization of Petroleum Exporting
Countries)- Countries that control the oil supply and manipulate prices of gas
How do they work?
• Collusion- Agreement between members to set prices and production levels
• Price Fixing- Agreement to sell at the same or similar prices
• Both are illegal in US

Market Power
• Def: the ability of a company to control prices and output
• Markets dominated by monopolies and oligopolies have great market power
• Markets with many sellers (mono and perfect comp) have little to no market power
Predatory Pricing
• Def- setting the market price below cost levels for the short term to drive out competitors.
Firms in perfect comp. and mono comp. do this to gain market power
Ex: Open up my pizza shop and sell slices for $1 even though it costs $1.50 to make. I can raise the price later if I drive out competition.
Government and Competition
• The Government keeps firms from controlling prices and supply of important goods. Antitrust Laws are laws that encourage competition and break up monopolies/oligopolies in the marketplace.
4 Forms of Anti-Trust Laws
1. Regulating Business Practices-gov’t intervenes if too powerful
2. Breaking Up Monopolies- (Standard Oil AT&T)
3. Blocking Mergers- Can stop them4. Preserving Incentives-must show benefits to
consumer
