Identify the correctly matched statements from Column I to that of Column II:
Monopoly: A monopoly is a firm who is the sole seller of its product, and where there are no close substitutes. An unregulated monopoly has market power and can influence prices. Examples: Microsoft and Windows, DeBeers and diamonds, your local natural gas company. Perfect Competition: Perfect competition is an ideal type of market structure where all producers and consumers have full and symmetric information, no transaction costs, where there are a large number of producers and consumers competing with one another. Perfect competition is theoretically the opposite of a monopolistic market. Examples of this perfect market structure are: A large number of buyers. A large number of sellers. Every participant is a price taker, not having the ability to influence market prices.
Oligopoly: The distinctive feature of an oligopoly is interdependence. Oligopolies are typically composed of a few large firms. Each firm is so large that its actions affect market conditions. Therefore, the competing firms will be aware of a firm's market actions and will respond appropriately.
