Monopoly

MONOPOLY A monopoly is an enterprise that is the only seller of a good or service. In the absence of government intervention, a monopoly is free to set any price it chooses and will usually set the price that yields the largest possible profit. Just being a monopoly need not make an enterprise more profitable than other enterprises that face competiton the market may be so small that it barely supports one enterprise. But if the monopoly is in fact more profitable than competitive enterprises, economists expect that other entrepreneurs will enter the business to capture some of the higher returns. If enough rivals enter, their competition will drive prices down and eliminate monopoly power.
Why do economists object to monopoly? The purely “economic” argument against monopoly is very different from what noneconomists might expect. Successful monopolists charge prices above what they would be with competition so that customers pay more and the monopolists (and perhaps their employees) gain. It may seem strange, but economists see no reason to criticize monopolies simply because they transfer wealth from customers to monopoly producers. That is because economists have no way of knowing who is the more worthy of the two parties—the producer or the customer. Of course, people (including economists) may object to the wealth transfer on other grounds, including moral ones. But the transfer itself does not present an “economic” problem.
Rather, the purely “economic” case against monopoly is that it reduces aggregate economic welfare (as opposed to simply making some people worse off and others better off by an equal amount). When the monopolist raises prices above the competitive level in order to reap his monopoly. Profits, customers buy less of the product, less is produced, and society as a whole is worse off. In short, monopoly reduces society’s income. The following is a simplified example.
Consider the case of a monopolist who produces his product at a
