Book excerpt: The authors take the reader from the world of J.P. Morgan, when a private network of investment banks presided over a tumultuous market of competing entrepreneurial firms, to the world of Lee Iacocca, where the power of even the most celebrated chief executive is more than matched by the government. Morgan commanded; business leaders of the 1980s negotiate. Over the course of the twentieth century, corporations developed new means of innovating and of achieving efficiency and control of their political and market environments. -- Book Jacket.
