ABSTRACT: This chapter provides an overview of the economics of vertical mergers. The overview strongly supports, on both theoretical and empirical grounds, a presumption that vertical mergers are welfare enhancing and good for consumers. However, vertical mergers can be anticompetitive if they result in either foreclosure or enhanced coordination. The difficult challenge for enforcement policy is effectively distinguishing between anticompetitive and procompetitive transactions. The economics of vertical mergers can provide a basis for this distinction and thus inform optimal enforcement policy and the nature of vertical merger enforcement guidelines.
