This book highlights the role of "profiteers" in political efforts to expand market-based competition. Political struggles surrounding the gradual marketization of corporate control in Britain, Germany and France from the 1860s provide empirical illustration. The book maps and analyzes the path-dependent evolution of support for shareholder rights relating to takeover bids among key interest groups, including managers, creditors, shareholders, and takeover service providers, as well as among political parties. By comparing the self-reinforcing and self-undermining policy feedback of market-enabling and market-restraining rules, it helps explain why market containment is an uphill struggle, while market expansion becomes easier with time.
