Why is it that alongside the rise of antitrust in the past decades, we seen an equal rise in market concentration across the economy? Justin Nogarede, FEPS Digital Policy Adviser, and Michelle Meagher, competition lawyer and author of "Competition is Killing Us: How Big Business is Harming Our Society and Planet", explore this apparent paradox. Having looked at competition policy from a regulator’s perspective, as an academic, and a legal practitioner, she has some unique insights to share. The discussion starts with themes from her book, in which she challenges the centrality of competition in our discourse, and suggests antitrust should focus more on concrete questions of power and how to distribute it. Then the conversation shifts to the digital economy, ways to constrain the power of big tech, and the upcoming regulatory proposals and actions in the EU and US to do exactly that.
