Competition policy and agent discretion: transatlantic regulatory cooperation in the digital economy

Despite a framework of bilateral agreements governing cooperation in competition policy since 1991, the European Union (EU) and United States of America (US) established a new Joint Technology Competition Policy Dialogue in 2021, which was different from previous cooperation and separate from the transatlantic Trade and Technology Council. Drawing from the principal-agent literature, this article argues that the choice to establish the new Joint Dialogue can be understood as an exercise of discretionary authority by agents in different jurisdictions with similar preferences who responded similarly to the common external factor of digitalisation. Facing new and shared challenges arising from the digital economy, the EU and US competition authorities undertook a new effort at cooperation – the Joint Dialogue – through which regulatory agents at various levels can interact, exchange information and improve enforcement in a rapidly changing business environment.
