This volume provides an essential overview of one of the most important developments in economics, finance and law of the past generation: the growing realization of how the market for corporate control functions and why its operation is of crucial importance. Presenting seventeen seminal contributions, the book illustrates the importance of corporate control changes - mergers, acquisitions and other takeovers - in helping to align the interests of corporate shareholders and their managers. The mechanics of various takeover techniques (poison pills, greenmail and other gambits) are also explored alongside empirical research concerning the functioning of the market for corporate control. Including an original introduction, this book will appeal to researchers interested in a summary of the growing appreciation of the market for corporate control, and also to others seeking to understand this aspect of the relationship between the economics and the law of the modern corporation.
