has pricing power within the market. There is only one supplier who has significant market power and determines the price of its product. A pure monopoly faces little competition because of high barriers to entry, such as high initial costs, or because the company has acquired significant market influence through network effects, for instance.
One of the best examples of a pure monopoly is the production of operating systems by Microsoft. Because many computer users have standardized on software products that are compatible with Microsoft's Windows operating system, most of the market is effectively locked in, because the cost of using a different operating system, both in terms of acquiring new software that will be compatible with the new operating system and because the learning curve for new software is steep, people are willing to pay Microsoft's high prices for Windows.
