Extrait:
We all know Microsoft, the biggest producer of operating systems in the world, which has almost 95% of the total market under its influence. This firm faces no real competitors — its market is thus said to be incontestable — and has therefore an important market power. This situation is called a monopoly. A monopoly is opposed to perfect competition, in which a great number of suppliers compete against one another, by selling at the market price and have therefore no market power. The problem is that the lack of competition due to a monopoly situation, incites the monopolist — as we are going to show — to over-price and under-supply. Hence, regulating a monopoly seems a fair response. But what can one do if a monopoly situation is the only possible way to produce a good or service, that is, a situation of natural monopoly? The question arises: should a natural monopoly be regulated or not?
