Much of the history of corporate law has concerned itself not with shareholder power, but rather with its absence. Recent shifts in capital market structure require a reassessment of the role and power of shareholders. These original, specially commissioned contributions by leading scholars in corporate law and financial economics provide a contemporary analysis of shareholder power and consider the regulatory consequences of changing ownership patterns around the world. The book begins with chapters on shareholder activism by institutional investors, hedge funds, and controlling shareholders. Further chapters explore the relationship between shareholders and the board of directors, shareholder activism around mergers and acquisitions, and turf battles during shareholder litigation. The final section offers a number of international perspectives on shareholder power in Asia, Europe, and the Americas. Students and scholars of corporate law will value the Handbook's timely exploration of modern shareholder power as well as its fresh perspective and scope.
