Since the 1970s, public and civil society dissatisfaction with the global power of corporations has generated a growing wave of new institutional mechanisms that attempt, in different ways, to create more accountable, responsible, and transparent businesses. These institutional mechanisms have become part of a much-larger social movement that is attempting to develop a set of constraints on business that stands in stark contrast to the dominant economic logic of maximizing shareholder wealth and growing multinational corporations' size and power. The Difference Makers is a history and detailed analysis of how corporate responsibility has emerged as a key political, social, and business issue, why it has evolved so quickly, and what the visions of its thought leaders are for the future.
