3 Definition of Market Market is an area where buyer and seller meet with each other for the purpose of exchange of goods and services for money. TIME Market can be classified into three main categories according to time. Very short period , Short Period Market, and Long Period Market SPACE According to this classification the market can be divided into four categories. Local Market, Regional Market, National Market, or International Market. Commodities A market can also be divided according to the type of commodities it deals in. In this division we have the following types of market. General Market, Specialized Market, Capital Market, Foreign exchange Market etc

4 Types of advertising Competitive Advertising: Your product is better than the substitutes available Informative Advertising: To give information on price, quality, special features about product.

5 CLASSIFICATION OF MARKET
Perfect Competition. Imperfect Competition.

6 Perfect Competition – has a very large number of sellers (hundreds or thousands) of the same product (any agriculture or fishery product). They are all selling the same undifferentiated products (oranges). Competition – economic rivalry among businesses. 5 Market Structure – degree of competition among firms operating in the same market (autos).

7 Four Market Conditions Necessary For Perfect Competition
1. Very large number of sellers (hundreds or thousands). Each seller will have only a small share of the market. 2. Similar or identical products (sweet corn/brocolli/eggs) which means there is no reason for non-price competition. C Easy entry and exit into the market. 4. Absence of price controls (too many sellers & consumers). Firm is price taker. Perfect Competition and Price No one firm controls price. Lowering price would lower profits as consumers would buy similar substitutes. Prices are set by the market rather than by the firms. These firms are “price takers.”

8 Sellers try to decrease competition by making their products different
Monopolistic Competition – fairly large number (25-75) of sellers competing to sell slightly differentiated products. Product differentiation (real or imaginary) is vital. This is the most common market structure. Sellers try to decrease competition by making their products different from the others. Since each firm attempts to make its product unique, unique, there is an “element of monopoly”, thus monopolistic competition. Product differentiation, when it is successful, enables a firm to “establish a kind of monopoly” so that loyal customers will prefer it rather than buy from the competition. [They try to monopolize a small portion of the market.]

9 Even virtually identical products may be differentiated
by brand name, packaging, or design but they are still similar. They have all the conditions of perfect competition except for product “differentiation.” They use “nonprice” methods of competition such as advertising and improved service to increase sales. Reputation is important [builds loyalty]. Most manufactured goods are made by only a few producers.

10 4 Market Conditions For Monopolistic Competition
Farily large number of sellers must exist. 2. The products are similar but they emphasize product differentiation (differences among products). This is the one thing that separates monopolistic competition from perfect competition. The differences may be real or imaginary (a refrigerator with plastic or metal trays). Aspirin, by federal law, has to have certain chemicals but people believe highly advertised aspirin is better. Revlon offers 157 shades of lipstick – 41 are pink. 3. Buyers must be well informed about differences in products. Monopolistic competitors rely on informative and competitive advertising. 4. Easy to enter or exit the industry. Few restrictions exist.

11 Examples of Monopolistic Competition
Monopolistic Competition [element of monopoly [differentiation uniqueness] so called monopolistic competition] This is the most common market structure – over 99% of all firms. Examples of Monopolistic Competition Blue Jeans Grocery Stores Candy Bars Dry Cleaners Rock Concerts Pizza Shoe Stores Cassette players Chicken Toothpaste Book Stores Soaps and detergents Restaurants Vacuum Cleaners Furniture Stores Barbershops Beauty Parlors Econ Textbook Co’s The “Real World” The “real world” of competition involves monopolistic competition & oligopolies. Over 99% of all firms are monopolistic competitors. However, a few thousand oligopolies produce most of the products in the U.S. So, our big firms are oligopolists and our smaller firms are monopolistic competitors. “Econ” “Econ,Econ”

12 Two Types of Oligopolies
2Oligopoly – “the chosen few” (3 or 4) firms control 70% of the market. Monopoly – 1 firm industry (Cable TV) Duopoly – 2 firm industry. (Coke & Pepsi) [P&G (47%) & Kim-Clark (30%) in diapers] “Oligo” – few in an industry. (“Big 3 or 4” or even “Big 5 or 6”) Two Types of Oligopolies Pure (Undifferentiated) Oligopoly – 3 or 4 producers dominate the production of an identical product (steel, zinc, copper, aluminum, lead, cement, etc) Differentiated Oligopoly – 3 or 4 producers dominate the production of differentiated (similar) products. [typewriters, tires, soap, cigarettes, refrigerators, cereals, TVs & autos]

13 Oligopoly Examples Athletic Shoes–“Big 4”–Nike, Reebok, New Balance, Adidas, Cereals – “Big 3” – Quaker Oats, General Mills, & Kelloggs TV Networks – “Big 4” – NBC, CBS, ABC & Fox There are also oligopolies in chewing gum, light bulbs, typewriters, photocopiers, and sewing machines.

14 Four Market Conditions For Oligopolies 1
Four Market Conditions For Oligopolies 1. A few sellers control over 70% of market. 2. Firms offer identical or differentiated products (real or imaginary). Advertising important. 3. Product information must be easily available. They use informative advertisement (price, quality, and special features) to introduce new products. 4. There are huge barriers to entry into the industry. The three major barriers are technological knowledge, money, & brand name loyalty. Entry is difficult because many have patents or own essential raw materials. This makes it difficult for new firms to try to compete. Oligopoly and Price Oligopolies control price to some degree by creating brand name loyalty and using non-price competition.

15 Monopoly – the “power of one”
PalmTran SRCHS Greyhound Waste Management DART Natural Monopoly Competition would be chaotic. It is natural to give it to one co. Ex: Utilities Cable TV Government Monopoly Owned & operated by G Ex: U.S. Mail State Highways U.S.Mail “Price Makers” TXU Monopoly [mono(1) poly (seller)] Control over price: Total Product: unique Ex: Comcast Cable TV Cable TV Rubik’s Cube Technological Monopoly “Patent” Ex: Rubik’s Cube Geographic Monopoly Only seller in a specific area Example: Remote Store Cable TV Monopoly – the “power of one”

16 Pure Monopoly – one firm industry [“monopolist”]
Pure Monopoly’s Market Condition 1. One firm is the only seller. Advertising promotes image. 2. No close substitute goods are available. 3. Prohibitive barriers to entry in the industry. High invest- ment costs and technological expertise prevent others from entering the market. Legal restrictions make entry in government-supported monopolies nearly impossible. 4. Almost complete control of market price. 9 Monopolist have much control over price because they are the only seller. A higher price would hurt demand. The state may control the price on some legal monopolies. These single suppliers are “price makers.”

17 Four Types of Legal Monopolies
1. Natural Monopoly – where competition would be chaotic, it is natural to give the business to one firm. Imagine the confusion if 5 different busses raced each other to the corner to pick up a passenger. Competition would be impractical, inconvenient, & unworkable. Greyhound Examples: Public Utilities (electric & gas) – privately owned companies (buses-Continental Trailways) but regulated by the government. Comcast Cable TV in Plano. The government monitors the natural monopolies to ensure that they provide quality service at reasonable rates. Waste Management

18 2 Government Monopoly – monopoly owned and operated by the government.
The difference between natural [privately owned] & government monopolies [government owned] is that these monopolies are owned operated by any level of government. Examples would be interstate highway system, public libraries, public schools, Postal Service, & DART. In most cases, government monopolies deal with economic products needed for the public welfare but which people would not be provided adequately by private industry. Most tend to provide goods that enhance the general welfare rather than seek profits. Pilot Point High [Local G] State G Federal G Dart Dart

19 3 Geographic Monopoly – when a firm is the only seller of a good in a specific location.

20 4. Technological Monopoly – results from the
invention of a new product (patent) or when technology changes the way a good is produced. 16 A patent gives an individual or firm exclusive right to pro- duce, use or dispose of an invention or discovery for 20 years from the date of filing. To obtain a patent, you must go to the Patent Office after doing research to make sure the patent has not already been patented. Then You hire a patent lawyer to file your patent. All of this takes about 18 months. The total cost for a patent runs about $5,000. 17 It is very expensive to wage a patent infringement suit, around $300,000.

25 A Summary of Market Structures

26 Cartels A cartel is an organization of independent firms whose purpose is to control and limit production and maintain or increase prices and profits.

27 Equilibrium of a firm in Monopolistic competition
The firm whether operating under perfect competition or Monopoly, wants to maximize profit. In order to achieve this objective the firms goes on producing a commodity as long as the MR is greater than MC. When MR=MC, it is then in equilibrium and produces the best level of output. If a firm produces less than or more than the MR=MC output, it will then not be making maximum of profits.

28 Four cases of price and output determination under Perfect Competition
Following are the possible cases in perfect competition. A firm will earn Super Normal profit ,if the point where MR=MC is greater than ATC A firm will earn Normal profit ,if the point where MR=MC=ATC A firm will Incur Loses if MR=MC is below ATC A firm will Shut down if the point where MR=MC is even above the AVC.

29 Costs Relevant to a Firm
P = MR Output Total Cost Marginal Cost Average Total Cost Total Revenue Profit TR-TC 40.00 –40.00 35.00 1 68.00 28.00 –33.00 2 88.00 20.00 44.00 70.00 –18.00 3 104.00 16.00 34.67 105.00 1.00 35.00 4 118.00 14.00 29.50 140.00 22.00 5 130.00 12.00 26.00 175.00 45.00 6 147.00 17.00 24.50 210.00 63.00 7 169.00 24.14 245.00 76.00 8 199.00 30.00 24.88 280.00 81.00 9 239.00 40.00 26.56 315.00 10 293.00 54.00 29.30 350.00 57.00

32 The Shutdown Point The shutdown point is the point at which the firm will be better off, if it shuts down because it cannot even cover Average Variable Costs.

34 Spot Quiz.. Here is the graph of Rake making company showing abnormal profit. Find the following; 1 MR ? 2 Profit per unit? 3 Profit maximizing Quantity

35 Long-Run Competitive Equilibrium
Zero profit does not mean that the entrepreneur does not get anything for his efforts. Normal profit – the amount the owners of business would have received in the next-best alternative.

36 2 Monopolistic competition
Large number of firms in the industry May have some element of control over price due to the fact that they are able to differentiate their product in some way from their rivals – products are therefore close, but not perfect, substitutes Entry and exit from the industry is relatively easy – few barriers to entry and exit

37 Price and output determination under Monopolistic competition
Maximizing Profits Firms produce the quantity where MC =MR and charge the highest price that sells that quantity

38 Case 1 Abnormal Profit MC AC AR MR $180 P $150 Price per Gallon $ 140
$100 E 12,000 Gallons of Gasoline per Week
