A key challenge for competition agencies, particularly in digital markets, is the multi-sided nature of some of the markets that they analyse. In June 2017 the OECD held a hearing to look at an important question that competition agencies face: Are the tools traditionally used to define markets, and to assess market power, exclusionary conduct, vertical restraints, or efficiencies, sufficient to address those questions in the context of multi-sided markets? Moreover, if they do need rethinking, how might these be redesigned or reinterpreted to equip agencies with the analytical tools they need in multi-sided markets. At the hearing, a range of expert economists from agencies, academia, and private practice presented and discussed practical methodological proposals to deal with such recurring questions for many competition agencies. All papers and presentations can be found on this page. The compilation of papers and an OECD introductory chapter has been published as a separate publication in April 2018.
