Perfect CompetitionIn a perfectly competitive market, a large
number of firms produce essentially the same product. All goods are sold at their equilibrium price. This is the most efficient market structure.Rare. Mostly agricultural.Examples. Wheat, corn, tomatoes, milk,
commercial fishing, paper industry.

Characteristics of Perfect CompetitionMany producers and consumers. Large number of participants promotes competition.
Identical products. Buyers don’t really see a difference: milk is milk.Commodity. A product that is exactly the same no matter who produces it. Grains, cotton, sugar, oil.

Characteristics of Perfect CompetitionEasy Entry into Market. Few
restrictions. Existing producers will face competition from new firms, and no single firm will dominate the market.
No Control over Prices. Producers can not influence prices because there are too many other producers offering the same product. Market forces of supply and demand determine price of goods (Invisible Hand!).

Barriers to EntryBarrier to Entry. Obstacle that can
restrict access to a market and limit competition.Start-up costs. Initial expense of starting a
business.Financial capital.Control of resources. Both physical and human
capital.Technology.

If this is rare, why isperfect competition important?Perfect competition is the standard by which we measure all the other markets.One structure to rule them all, one structure to find them...one structure to measure them all and in the darkness box them squarely on the ears.

MonopolyMonopoly. Market or industry consisting
of a single producer of a product that has no close substitutes.
Monopolies are generally illegal.Government uses antitrust laws to limit the
formation of monopolies.One key thing to remember throughout
monopoly: control of price and output!

Characteristics of MonopolyOne producer. No competition. The
monopoly is the market.Unique product. Monopolies are the only
supplier of the product. No good substitutes, no similar goods or services.What kind of product did we call this?
The one where no matter how high the price went, consumers would still keep buying it?
![Page 15: Economics Mr. Bordelon Market Structures. Market Structure Market structure. The organization of a market based on the degree of competition among producers](https://reader038.vdocuments.net/reader038/viewer/2022110401/56649dde5503460f94ad6ed8/html5/thumbnails/15.jpg)
Characteristics of MonopolyHigh Barriers to Entry. Since the
monopoly controls everything, it’s difficult if not impossible to get into the market at all.
High Control over Prices. Monopolists control price and output. They can set price without fear of being undercut by competitors. They can limit supply and create a shortage to raise the price even further.

Natural MonopolyNatural monopoly. When a single firm
can supply a good or service more efficiently and at a lower cost than two or three competing firms can.Examples. Utilities, airports.Because natural monopolies are efficient,
governments view them as beneficial.

Natural MonopolyEconomies of scale. Greater efficiency
and cost savings that result from increased production.Businesses that acheive economies of scale
lower its average cost per unit of production by increasing its output and spreading fixed costs over a larger quantity of goods.Huh?

Natural MonopolyEconomies of Scale cont’dBob the Builder has been asked to supply
water to a new subdivision of 50 houses. To do this, it will cost his company $100,000 to put the pipes in. It costs an addition $1,000 to put in a meter.Total cost for supply water to the first
home: $101,000

Natural MonopolyEconomies of Scale cont’d• Businesses that acheive economies of scale
lower its average cost per unit of production by increasing its output and spreading fixed costs over a larger quantity of goods.
• In other words, it costs me less to build per unit because I can spread out the cost of the whole project to each product I build.
• Bob the Builder’s average total cost will decrease as he increases his production!

OligopolyOligopoly. Market or industry dominated
by just a few firms that produce similar or identical products.
Arise because of economies of scale, which give bigger producers an advantage over smaller ones.
Some competition.Firms in an oligopoly do not have to be as
large.

Characteristics of OligopolyFew Producers. Small number of firms
control the market. If top four producers supply more than 60% of the market, then this is an oligopoly.
Similar Products. Same product, minor variations.
![Page 34: Economics Mr. Bordelon Market Structures. Market Structure Market structure. The organization of a market based on the degree of competition among producers](https://reader038.vdocuments.net/reader038/viewer/2022110401/56649dde5503460f94ad6ed8/html5/thumbnails/34.jpg)
Characteristics of OligopolyHigh Barriers to Entry. High start-up
costs, existing firms may have made large investments and enjoy economies of scale, customers reluctant to give up loyal to old brands.
Some control over price. Some competition. Firms influenced by price decisions of other firms in market—interdependence.
![Page 35: Economics Mr. Bordelon Market Structures. Market Structure Market structure. The organization of a market based on the degree of competition among producers](https://reader038.vdocuments.net/reader038/viewer/2022110401/56649dde5503460f94ad6ed8/html5/thumbnails/35.jpg)
When Oligopolies Behave BadlyOligopolies are not in and of themselves
illegal. However, they can act illegally. Or sometimes just misbehave.
![Page 36: Economics Mr. Bordelon Market Structures. Market Structure Market structure. The organization of a market based on the degree of competition among producers](https://reader038.vdocuments.net/reader038/viewer/2022110401/56649dde5503460f94ad6ed8/html5/thumbnails/36.jpg)
When Oligopolies Behave BadlyPrice Leadership. In an oligopoly
dominated by a single firm, the dominant firm sets a price and other smaller firms may follow.However, dominant firm may cut prices in
order to take business away from competitors or force them out of business—anti-competitive! Bad!
If others lower their prices, market could enter a price war, benefiting consumers, but bad for sellers.
![Page 37: Economics Mr. Bordelon Market Structures. Market Structure Market structure. The organization of a market based on the degree of competition among producers](https://reader038.vdocuments.net/reader038/viewer/2022110401/56649dde5503460f94ad6ed8/html5/thumbnails/37.jpg)
When Oligopolies Behave BadlyCollusion. When producers get together
and make agreements on production levels and pricing.Illegal. Unfairly limits competition.
![Page 38: Economics Mr. Bordelon Market Structures. Market Structure Market structure. The organization of a market based on the degree of competition among producers](https://reader038.vdocuments.net/reader038/viewer/2022110401/56649dde5503460f94ad6ed8/html5/thumbnails/38.jpg)
When Oligopolies Behave BadlyCartel. Organization of producers
established to set production and price levels for a product.Illegal in the United States.Not on global market.
OPEC. Organization of the Petroleum Exporting Companies often set price and output (hey, that sounds familiar!) artificially.
Works primarily with commodities: oil, sugar, coffee, etc.

When Oligopolies Behave BadlyKey point! When firms in an oligopoly
work together to control the market, they act like a monopoly. As such they can use market power to limit competition and raise prices.
![Page 40: Economics Mr. Bordelon Market Structures. Market Structure Market structure. The organization of a market based on the degree of competition among producers](https://reader038.vdocuments.net/reader038/viewer/2022110401/56649dde5503460f94ad6ed8/html5/thumbnails/40.jpg)
Monopolistic CompetitionMonopolistic Competition. Large
number of producers provide goods that are similar but varied.
Oftentimes this means creating a brand, which consumers will show brand loyalty to.

Characteristics ofMonopolistic CompetitionMany Producers. Many competitors
means more competition.Differentiated products. Similar
product, with significant variations.Product differentiation. Distinguish g/s
from other firms, even when those products are close substitutes for each other.
Examples. Shoes—Nike, Reebok. Computers—HP, Apple.

Characteristics ofMonopolistic CompetitionFew Barriers to Entry. Start-up costs are
relatively low. Many firms can enter and earn a profit.
Some Control over Prices. Because producers control their brands, they have some control over price. BUT because products are close substitutes, market power is limited.If prices raise too much, customers will
substitute.Too many producers for price leadership
or collusion to be possible.

Questions1.The differences between perfect competition and monopolistic
competition arise because(a) in perfect competition the prices are set by the government.(b) in perfect competition the buyer is free to buy from any seller he
or she chooses.(c) in monopolistic competition there are fewer sellers and more
buyers.(d) in monopolistic competition competitive firms sell goods that are
similar enough to be substituted for one another.
2.An oligopoly is(a) an agreement among firms to charge one price for the same
good.(b) a formal organization of producers that agree to coordinate price
and output.(c) a way to attract customers without lowering price.(d) a market structure in which a few large firms dominate a market.

Price DiscriminationPrice Discrimination. Division of
customers into groups based on how much they will pay for a good.
Market Power. Ability of a company to change prices and output.
Targeted Discounts. Discounts aimed at characteristics of a particular consumer—elderly, students, military, etc.

Price Discrimination1. Some market power. MUST have some
control over prices.2. Distinct consumer groups. Divides
customers into distinct groups based on sensitivity to price.
3. Difficult resale. If one group of customers could buy the product, then resell it to someone else for a profit, then the firm can not enforce price discrimination.

through ways other than lower prices.Differentiation. Making a product
different from other similar products.
