The new research also shows that monopolists typically increase prices by using political machinery to limit the output of competing products—usually by blocking low-cost substitutes. By limiting supply of these competing products, the monopolist drives up demand for its own. Thus, in contrast to conventional theory, the monopolist actually produces more of its own product than it would in a competitive market, not less.
