The Digital Markets Research Hub is an independent academic initiative aiming at scrutinising the functioning of competition/regulation in digital markets. We host one-to-one interviews with the leading thinkers, policymakers, regulators and practitioners. We also organise online mini-workshops inviting high-profile experts in various fields of digital competition law & policy to discuss the most vibrant issues of the ongoing regulatory reforms in digital markets.
