Modern corporations

By the end of the nineteenth century the forces of limited liability, state and national deregulation, and vastly increasing capital markets had come together to give birth to the corporation in its modern-day form. The well-known Santa Clara County v. Southern Pacific Railroad decision began to influence policymaking. The decline of restrictions on mergers and acquisitions encouraged a wave of corporate consolidation: from 1898 to 1904, 1,800 U.S. corporations were consolidated into 157. The modern corporate era had begun.

The 20th century saw a proliferation of enabling law across the world, which helped to drive economic booms in many countries before and after World War I. Starting in the 1980s, many countries with large state-owned corporations moved toward privatization, the selling of publicly owned services and enterprises to corporations. Deregulation -- reducing the regulation of corporate activity -- often accompanied privatization as part of an ideologically laissez-faire policy. Another major postwar shift was toward the development of conglomerates, in which large corporations purchased smaller corporations to expand their industrial base. Japanese firms developed a horizontal conglomeration model, the keiretsu, which was later duplicated in other countries as well.
