This ninth edition of Managerial Economics and Business Strategy has been revised to include updated examples and problems, but it retains all of the basic content that made previous editions a success by teaching managers the practical utility of basic economic tools, such as; present value analysis, supply and demand, regression, indifference curves, isoquants, production, costs, and the basic models of perfect competition, monopoly, and monopolistic competition. This edition details the emphasis on real-world examples and modern topics along with unique coverage found nowhere else, such as; oligopoly, penetration pricing, multistage and repeated games, foreclosure, contracting, vertical and horizontal integration, networks, bargaining, predatory pricing, principal–agent problems, raising rivals’ costs, adverse selection, auctions, screening and signaling, search, limit pricing, and a host of other pricing strategies for firms enjoying market power. This balanced coverage of traditional and modern microeconomic tools makes it appropriate for a wide variety of managerial economics classrooms.
