This volume contains ten papers, by many prominent authors, examining antitrust issues of current interest. The first paper summarizes the other papers and presents original research on the meaning of consumer welfare and the sources of buyer power. The next five articles evaluate older antitrust cases to determine whether the decisions reached, the relief ordered, or both, enhanced consumer welfare. The seventh paper describes a new measure of efficiency that gives greater weight to consumer harm and applies it to a recent merger. The next paper explains a new way in which vertical foreclosure can enhance the market power of an upstream supplier. The ninth article refines an innovative technique for identifying substitutes among a set of differentiated products. The tenth paper confronts a contentious policy issue - the treatment of patent settlements in which the patent holder pays the challenger to exit the market - and concludes that they should be per se illegal.

Since 1979 "Research in Law and Economics" has been presenting original research that explores the extent to which the constraints of law explain economic behavior and the role of economics in forming the law. Leading scholars, including Kenneth Arrow, Kenneth Elzinga, Victor Goldberg, Jack Hirschliefer, Paul Joskow, and Vernon Smith, have chosen "Research in Law and Economics" as the right forum for presenting their research. Now published bi-annually, each issue of "Research in Law and Economics" focuses on a timely and relevant topic. Such topics have included economics of environmental policy, urban property rights, antitrust and evolutionary models in economics and law. This volume focuses on cost-benefit analysis and the law, whereas the next special issue will concentrate on corporate finance

Since 1979 Research in Law and Economics has been presenting original research that explores the extent to which the constraints of law explain economic behavior and the role of economics in forming the law. The first chapter in this volume proposes three different definitions for market power from an antitrust perspective. Chapter two suggests a new means of measuring market power by moving away from traditional indicators of averaging industry profits. The third chapter is an analysis of efforts exerted and utilities obtained in a double lawsuit. Chapter four surveys recent developments in economics of contract interpretation. The fifth chapter examines the impact of changes in foreign exchange legislation on the levels of R&D undertaken by pharmaceutical firms in India. Chapter six addresses the role of transaction costs in explaining governance in environmental economics can play in helping choose environmental policy tools. The final chapter is an examination of economic evidence relating to the allegations in litigation against cigarette manufacturers.
