v Market Structure –
Interconnected characteristics of a market, such as the number and relative strength of buyers and sellers and degree of collusion among them, level and forms of competition, extent of product differentiation, and ease of entry into and exit from the market
4 basic types of Market structure:
Ø Perfect Competition –
A market structure in which:
1. All firms sell an identical product.
2. All firms are price takers.
3. All firms have a relatively small market share.
4. Buyers know the nature of the product being sold and the prices
charged by each firm.
5. The industry is characterized by freedom of entry and exit.

Ø Monopoly -
A monopoly is a market structure in which a single supplier produces and sells the product. If there is a single seller in a certain industry and there are no close substitutes for the goods being produced, then the market structure is that of a "pure monopoly".
Ø Monopolistic Competition –
There are many sellers in an industry and/or there exist many close substitutes for the goods being produced, but nevertheless firms retain some market power.
Ø Oligopoly –
A particular market is controlled by a small group of firms. It is much like a monopoly, in which only one company exerts control over most of a market. In an oligopoly, there are at least two firms controlling the market.
| Characteristic | Perfect Competition | Oligopoly | Monopoly |
| Number of firms | Many | Few | One |
| Type of product | Homogenous | Differentiated | Limited |
| Barriers to entry | None | High | High |
| Pricing | Price taker | Price maker | Price maker |
| Profit maximization | -------- | Not always | Usually, but not always |
| Economic efficiency | High | Low | Low |
| Innovative behavior | Weak | Very Strong | Potentially strong |
- Market structure is important because it affects market outcomes through its impact on the motivations, opportunities and decisions of economic factors participating in the market.
