Regulation is an important tool to deal with market imperfections. Regulation might, however, sometimes go beyond what is socially justified and create undue restraints on competition. The problem of social engineering is thus to devise a system that will ensure that the optimum combination of...

Competition law constitutes an important part of the social contract that stands at the basis of market economies, which conceptualizes the relationship between the state and its citizens, as well as among citizens, and legitimizes state action. This article seeks to unveil the social contract...

Aggregate concentration has recently been recognized as an important source of competitive constraints. The concerns raised by it are, however, particularly difficult to deal with, largely because they do not lend themselves to straightforward solutions. This chapter examines the use of abuse of...

The next generation of e-commerce will be conducted by digital agents, based on algorithms that will not only make purchase recommendations, but will also predict what we want, make purchase decisions, negotiate and execute the transaction for the consumers, and even automatically form...

Recent studies have proven that pricing algorithms can autonomously learn to coordinate prices, and set them at supra-competitive levels. The growing use of such algorithms mandates the creation of solutions that limit the negative welfare effects of algorithmic coordination. Unfortunately, to...

Monopoly pricing per se, that is without need of proof of anti-competitive conduct or intent, is regulated very differently on both sides of the Atlantic, at least in theory. U.S. antitrust law sets a straightforward rule: monopoly pricing, as such, is not regulated. In contrast, under EC law...

Algorithms, especially those based on artificial intelligence, play an increasingly important role in our economy. They are used by market participants to make pricing, output, quality, and inventory decisions; to predict market entry, expansion, and exit; and to predict regulatory moves. In a...

One of the most important market imperfections in modern capitalism and surprisingly one of the most under-regulated is oligopoly pricing (conscious parallelism). Only few suggestions have been made over the years to regulate oligopoly pricing. All suggestions pose serious obstacles to their...

This article introduces a special symposium issue of the Antitrust Law Journal based on a conference on monopolization. It argues that monopolization law has been experiencing simultaneous expansion and contraction processes that are not wholly contradictory but at least partly complementary....
