Thanks to feedback from users around the world, Managerial Economics and Business Strategy remains the top selling managerial text in the market. I am grateful to all of you for allowing me to provide this updated and improved product. Before highlighting some of the new features of the seventh edition, I 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.
