Japan's government, at its best, understands this role better than anyone including the point that nations pass through stages of competitive development and that government's appropriate role shifts as the economy progresses. By stimulating early demand for advanced products, confronting industries with the need to pioneer frontier technology through symbolic cooperative projects, establishing prizes that reward quality, and pursuing other policies that magnify the forces of the diamond, the Japanese government accelerates the pace of innovation. But like government officials anywhere, at their worst Japanese bureaucrats can make the same mistakes: attempting to manage industry structure, protecting the market too long, and yielding political pressure to insulate inefficient retailers, farmers, distributors, and industrial companies from competition.
