Together with Progressive Policy Institute (PPI), the Washington DC-based think tank, The Lisbon Council convened for The 2019 Transatlantic Summit on Competition in the Digital Age, a high-level conference under the theme “facing the digital challenge together.” Michael Mandel, chief economic strategist at PPI, presented the key findings of Competition and Concentration: How the Tech/Telecom/eCommerce Sector is Outperforming the Rest of the Private Sector, his latest policy brief, which outlines the unique performance of the technology sector in the modern world – and the challenge of regulating it. Aleksandra Boutin, founding partner of Positive Competition; Adina Claici, director of Copenhagen Economics; Fabien Curto Millet, director of economics at Google; Kai-Uwe Kühn, professor of economics and deputy director of the centre for competition policy at the University of East Anglia; and Nicolas Petit, professor of school of law at the University of Liège and co-director of the Brussels School of Competition, led an all-star cast of top economists and regulators for a wide-ranging discussion on the unique challenges that the digital economy poses. The debate and conclusions will feed directly into the European Commission Shaping Competition Policy in the Era of Digitisation, chaired by Commissioner for Competition Margrethe Vestager.
