The history of MITI is central to the economic and political history of modern Japan. Equally important, however, the methods and achievements of the Japanese economic bureaucracy are central to the continuing debate between advocates of the communist-type command economies and advocates of the Western-type mixed market economies. The fully bureaucratized command economies misallocate resources and stifle initiative; in order to function at all, they must lock up their populations behind iron curtains or other more or less impermeable barriers. The mixed market economies struggle to find ways to intrude politically determined priorities into their market systems without catching a bad case of the "English disease" or being frustrated by the American-type legal sprawl. The Japanese, of course, do not have all the answers. But given the fact that virtually all solutions to any of the critical problems of the late twentieth century--energy supply, environmental protection, technological innovation, and so forth--involve an expansion of official bureaucracy, the particular Japanese priorities and procedures are instructive. At the very least they should forewarn a foreign observer that the Japanese achievements were not won without a price being paid.
