In this second volume of the Douglas H. Ginsburg Liber Amicorum, the reader will find a series of essays no less brilliant than those in the first. Emphasis is, rightly, placed on Judge Ginsburg’s contribution to the structured analysis of antitrust problems, whether in terms of the rule of reason, the shifting burden of proof, or the assessment of potentially anticompetitive mergers. The volume carries articles by distinguished contributors on some of the most important and topical questions in modern antitrust, and in doing so salutes the outstanding career of Judge Ginsburg, and adds significantly to the scholarship with which his name is already synonymous.
