This paper evaluates current antitrust policy in light of our current understanding of how transaction costs influence the ability of firms and consumers to deal with market power. The paper shows how the failure to consider transaction costs can lead to erroneous policy decisions. Many models...

As technology and interconnectivity have continued to flourish, so too has an important and complex form of enterprise: the platform. Services like Uber, Google Search, Hulu, and American Express cater to distinct but deeply-interdependent “sides” of customers that derive value or revenues...

This study constructs a model for examining anticompetitive exclusive supply contracts that prevent an upstream supplier from selling input to a new downstream firm. With regard to the technology to transform the input produced by the supplier, as an entrant becomes increasingly efficient, its...

This paper clarifies the relation between per se hub-and-spoke and vertical rule of reason antitrust analysis, the tension between which is illustrated with a detailed examination of the Apple e-books case

The Third Circuit's decision in Lepage's v. 3M created a great deal of uncertainty about the legality of so-called bundled discounts - i.e., discounts (or rebates) conditioned upon purchasing multiple products from disparate product markets. This paper, prepared for a joint Department of...

This paper provides an overview of recent developments in algorithmic antitrust, and the economics and legal issues raised in the areas of abuse of dominance, algorithmic pricing and collusion, and mergers and acquisition. The general theme is that while much has been made of the possible...

This study constructs a model of anticompetitive exclusive contracts in the presence of complementary inputs. A downstream firm transforms multiple complementary inputs into final products. When complementary input suppliers have market power, upstream competition within a given input market...

This study constructs a simplest model to examine anticompetitive exclusive contracts that prevent a downstream buyer from buying input from a new upstream supplier. Incorporating Nash bargaining into the standard one-buyer-one-supplier framework in the Chicago School critique, we show a...
