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.
