2. Perfect competition

The concept, competition, is used in two ways in economics. One way is as a state, or type of market structure. The other way is as a process. As a process, competition is prevalent throughout our economy.

Competition as a process is a rivalry among firms. It involves one firm trying to figure out how to take away market share from another firm.

Competition as a state, or market structure, is the end result of the competitive process under certain conditions.

A perfectly competitive market is a market in which economic forces operate absolutely. For a market to be called perfectly competitive, it must meet some stringent conditions:

1. Buyers and sellers are price takers.

2. No influence.

3. The number of firms is large.

4. There are no barriers to entry.

5. Firms' products are homogeneous (identical).

6. Exit and entry are instantaneous and costless.

7. There is complete information.

8. Selling firms are profit-maximizing entrepreneurial firms.

These conditions are needed to ensure that economic forces operate instantaneously and are unlimited by other invisible or visible forces.

3. Monopolistic competition

Imperfect competition exists when more than one seller competes for sales with other sellers of similar products, each of whom has some control over price. Individual sellers in such markets have a degree of monopoly power, which means they can influence on the price of their product by controlling its availability to buyers. Firms can control prices by differentiating their products either by quality or by brand.

Monopolistic competition exists when many sellers compete to sell a differentiated product in a market into which the entry of new sellers is possible. In a monopolistically competitive market:

1. There are relatively large numbers of firms, each satisfying a small, but not microscopic, share of the market demand for a similar, but not identical product. The market share of each rival firm is generally larger than it would have under perfect competition, but it's unlikely that any one firm satisfies not more than 10 percent of market demand.

2. The product of each firm is not a perfect substitute for the products of competing firms. Each seller's product has unique qualities or characteristics that cause some buyers to prefer it to products of competing firms. The product is therefore differentiated from any other product.

3. Firms in an industry don't consider the reaction of their rivals when choosing their product prices or annual sales targets. Because there are a relatively large number of firms in a monopolistically competitive industry, a firm's managers believe that their actions can't significantly reduce the market share of their rivals.

4. Relative freedom of entry and exit by new firms exists in monopolistically competitive markets. It's easy to set up new firms in monopolistically competitive markets. Entry may not be quite as easy as it is in perfect competition because new firms with new brands or product features may initially have difficulty establishing their reputations. Existing firms with established brands and reputations for service are likely to hold some competitive edge over new entrants.

5. Neither the opportunity nor the incentive exists for firms in the industry to cooperate in ways that decrease competition. The firms in a monopolistically competitive market don't cooperate to fix prices in order to increase their group profits. They can't effectively prevent new entrants from responding to profit opportunities by opening rival enterprises.
