Over the past decade two-sided and network markets have been the object of substantial research. One important result of the economic literature dealing with firms' behavior on such markets is that, due to the necessity to balance the interests of two different types of customers, related by cross-group externalities, it is often possible to see firms adopt strategies that would be sub-optimal otherwise. For instance, it is possible, even for monopolies, to consistently set the price below the marginal cost on one side of the platform in order to increase revenue on the other. Nevertheless, the antitrust implications of such private strategies have not been fully explored, and recent decisions by competition agencies such as the European Commission or the US DoJ (the Google case or the Deutche Borse/ NYSE-Euronext merger) indicate that substantial progress is still needed in the field of optimal public policy response to firms' strategies on such markets.
This workshop will address the issue of competition policy for platform and network markets. Invited practitioners and academics will debate during a panel discussion, a keynote address and two sessions (one dedicated to theory, another to empirics) to provide insight into the economic analysis and competition law implications of such markets.
Questions such as the following will be tackled:
