2. Outline of the Seminar

(1) Theme: “Competition law enforcement and competition regulation: the digital challenge”

(2) Outline of the Speech (Speaker's Message):

 The development of the digital sector is exceptionally fast and raises very complex questions regarding the monitoring of competition on digital markets. New organizational forms ( ecosystems)  combining a technological platform and third parties complementors compete with each other by offering innovative services on multi-sided markets. Competitors may follow different business models and may use their technological base to move across markets. Network effects may lead to market concentration and market  tipping. Data is a crucial input for some ecosystems’ business models allowing them to use artificial intelligence algorithms to simultaneously increase the quality of their services and  their economic power.  The traditional tools of competition analysis such as the hypothetical monopolist test to define relevant markets or the Lerner index to assess market power may be inadequate to analyze some of the dynamic competitive interactions on digital markets and new approaches may be necessary. Attempts to regulate digital ecosystems raise the question of the relevance of an ex ante approach to complement or be a substitute to the complex and slow ex post competition law enforcement in the dynamic digital sector. The talk will examine the current debate on those issues.

(3) Speaker: Frederic Jenny, Professor of economics, ESSEC Business School, Chair OECD Competition Committee
