Commodity
A buyer is not willing to pay more for one particular supplier’s product.
Buyers are concerned only with the price. Perfect Competition Buyers are fully informed about the price,
quality, and availability of products, and sellers are fully informed about all resources and technology.

Perfect Competition
Firms can easily enter or leave the industry. No obstacles preventing new firms from entering profitable.
A perfectly competitive firm is so small relative to the size of the market that the firm’s choice about how much to produce has no effect on the market price.

Market power
Is the ability of a firm to raise its price w/o losing all sales to rivals.
A perfect competitor has no market power. It has high barriers to entry, restrictions on
the entry of new firms into an industry. Allows to charge a price above the
competitive price.

Legal Restrictions

Patents, licenses, and other legal restrictions imposed by the government provide some producers w/ legal protection against competition.
Govn’t confer monopoly rights to sell hot dogs at civic auditoriums, collect garbage, offer bus & taxi service, & supply other services ranging electricity to cable t.v. .

Economies of scale
A monopoly sometimes emerges naturally when a firms experiences substantial economies of scale, as reflected by the downward-sloping , long-run average cost curve.
Single firm satisfy market demand at a lower average cost per unit than could two or more smaller firms.
Market demand is not great enough to allow more than one firm to achieve sufficient economies of scale.

continued
A monopoly that emerges from the nature of costs is called a natural monopoly.
New entrant cannot sell enough output to experience the economies of scale enjoyed by an established natural monopolist. Entry into the market is naturally blocked .
Less populated areas, natural monopolies include the only grocery store, movie theater, restaurant for miles around. (geographic monopolies).

Control of Essential Resources
Control of critical resources Decades Alcoa controlled bauxite,
aluminum. China is a monopoly supplier of panda to
the world zoo’s. Since 1930s, world’s diamond trade De
Beer.

Monopolists may not earn a profit
The demand curve for a monopolist’s output also is the market demand curve.
True monopolies are rare b/c a profitable monopoly attracts competitors & substitutes.
Technological changes may allow for new entries into new monopolies.

Monopoly and Efficiency
Monopoly Versus Perfect Competition Competition forces firms to be efficient- that is ,
to produce the maximum possible output form available resources- and to supply the product at the lowest possible price.
Consumers get a substantial consumer surplus from this low price. Monopolists would charge more than competitive firms, fewer consumers will be able to afford to buy the product.

Other problems w/ Monopoly
Resources wasted securing monopoly privilege. Influence political system, which thy use to
protect and strengthen their monopoly power. Lawyer’s fee, lobbying expenses, gathering
special privileges from govn’t are largely a social waste. Scarce resources are not added to output of unit.
Monopolies may grow inefficient,lazy, fat, not innovative in production techniques, reluctant to make new products.

Economies of scale-a monopolist might be able to produce output at a lower average cost than could competitive firms. Price, or the cost of production could be lower w/ monopoly than w/ perfect competition.
