Thanks to feedback from users around the world, Managerial Economics and Business Strategy remains the top selling managerial text in the market. We are grateful to all of you for allowing us to provide this updated and improved product. Before highlighting some of the new features of the eighth edition, we would like to stress that the fundamental goal of the book—providing students with the tools from intermediate microeconomics, game theory, and industrial organization that they need to make sound managerial decisions—has not changed.
