'Blair and Harrison provide a clear, approachable, and useful analysis of the economics of monopoly on the buying side of markets, a subject that is much too frequently both overlooked and misunderstood. The authors also include a comprehensive, policy-driven analysis of bilateral monopoly and show how monopsony power is exercised in a number of markets, including agriculture, sports leagues, and medical services. This excellent, well-written, and timely book should be on the shelf of every industrial organization economist as well as every competition or antitrust lawyer.' Herbert Hovenkamp, University of Iowa
