Principles of Corporate Finance is the worldwide leading text that describes the theory and practice of corporate finance. Throughout the book the authors show how managers use financial theory to solve practical problems and as a way of learning how to respond to change by showing not just how but why companies and management act as they do. The text is comprehensive, authoritative, and modern and yet the material is presented at a common sense level. The discussions and illustrations are unique due to the depth of detail blended with a distinct sense of humor for which the book is well known and highly regarded. This text is a valued reference for thousands of practicing financial managers. Richard A. Brealey and Stewart C. Myers welcome Franklin Allen as a new coauthor to this Eighth Edition. Sometimes the addition of a new coauthor means that one of the existing authors proposes to take a back seat. That is not the case with this team. Dr. Allen’s addition represents a genuine increase in capacity and brings fresh expertise and ideas to an already tremendously successful textbook and partnership.
