Monopoly is nearly always seen as something undesirable. Courts have wrestled with monopoly for ages, sometimes defining it as: "the power to control prices and exclude competition", "restraining trade", or "unfair and anti-competitive behavior." Should monopolistic practices be condemned and outlawed?
Let's look at anti-competitive behavior and practices, but let's not confine ourselves to what's traditionally seen as monopoly.
Monopoly means that a firm is sole seller of a product without any close substitutes, controls over the prices the firms charge. Government sometime grants a monopoly because doing so is viewed not only to be in the public interest, but also to encourage it with price incentives. However, monopolies fail to meet their resource allocation efficiently, producing less than the socially desirable quantities of output and charging prices above marginal cost. Thus, this inefficiency of monopoly causes the quantity sold to fall short of social needs.
Law
The existence of a very high market share does not always mean consumers are paying excessive prices since the threat of new entrants to the market can restrain a high-market-share company's price increases. Competition law does not make merely having a monopoly illegal, but rather abusing the power a monopoly may confer, for instance through exclusionary practices (i.e. pricing high just because you are the only one around.) It may also be noted that it is illegal to try to obtain a monopoly, by practices of buying out the competition, or equal practices. If one occurs naturally, such as a competitor going out of business, or lack of competition, is not illegal until such time as the monopoly holder abuses the power.
Certain categories of abusive conduct are usually prohibited by a country's legislation. The main recognized categories are: * Limiting supply * Predatory pricing *
