This work focuses on the economic challenges the American economy has met during the post-World War II era, and on the new challenges--represented notably by the competing economies of Japan, Germany, and the entire European union--that confront it as the twenty-first century approaches. The book shows how the transformations brought about by international competition fit the long-term processes of economic growth and change with respect to structural mutations, technological development, the role of the government, and the evolution of government-business relations. Nicholas Spulber presents a detailed critique of the thesis alleging that the American economy had experienced some kind of decline, and argues that the economy will continue to move forward energetically and successfully if growth and change are primarily left to emerge from the impulses and incentives of the private economy.
