Blockchain may transform transactions the same way the Internet altered the dissemination and nature of information. If that were to be the case, all relationships between companies would change, including prohibited ones such as collusive agreements. For that reason, the stakes are crucial and...

This paper proposes an understanding of abuse of collective dominance or shared monopolization that does not outlaw oligopolistic tacit collusion as such, but that reputes abusive a set of tactics adopted by tacitly colluding oligopolists exposed to disruption. As much as deviation is an...

This paper explores the concept of vertical restraints or restrictions. It includes references to the competition law regimes of the European Union (EU), United States (US), and the People's Republic of China, as well as the key case law. It is part of the Concurrences' Global Dictionary of...

We revisit the pros and cons of cartel criminalization with focus on its possible introduction in the EU. We document a recent phenomenon that we name EU ``leniency inflation", whereby leniency has been increasingly awarded to many, and sometimes all members of a cartel. We argue that, coupled...

Every year the UK government spends billions of pounds purchasing goods, works and services that are vital to growth, development, health and social welfare. Performed well, public procurement helps a government to nurture competition, save money, and provide better public services. These...

Governments around the world spend an estimated $9.5 trillion of public money purchasing goods and services each year (public procurement). Not only does this represent a significant proportion of government expenditure (29.1 percent on average in OECD countries) and of total gross domestic...

Antitrust and competition law have grown dramatically in importance and significance over the last fifty years. US antitrust law has been the principal source of inspiration for jurisdictions wishing to introduce regulation to control cartels and monopolization, and antitrust regulation has now...

Current controversies over patent policy place standard-setting organizations (SSOs) on a collision course with antitrust law. Recent theoretical research conjectures that, in an SSO, patent owners can “hold up” patent users in the sense of demanding high royalties for a patented input after...

Algorithmic competition has arrived. With it has come the specter of algorithmic collusion – rapid detection of co-conspirators’ defection via technologically enhanced price monitoring and setting capability can encourage anticompetitive collusion. Strikingly, the ability to track...

Complexity science is widely used across the policy spectrum but not in antitrust. This is unfortunate. Complexity science enables a rich understanding of competition beyond the simplistic descriptions of markets and firms proposed by neoclassical models and their contemporary neo-Brandeisian...
