The article discusses the main problems of antitrust regulation of multilateral digital platforms. The problems of defining the boundaries of product markets on which multilateral platforms operate, including the problems of analyzing competition in derivative markets, other stages of determining the dominant position of a digital platform and its market power are disclosed. In the context of the latest news related to the proposals of the Subcommittee of the US Congress on toughening antitrust regulation of digital giants (Amazon, Facebook, Google, Apple), the possibilities of using such proposals in the Russian practice of antitrust regulation are considered. The author identifies the methodological problems that arise in the context of strengthening the market power of digital platforms, and also reveals the author’s approach to solving these problems.

Abstract Competitive markets can benefit consumers, workers, entrepreneurs, small businesses, and the economy more generally but several indicators suggest the persistence of high levels of market concentration in many of South Africa’s economic sectors. The causes underlying the high levels of concentration and corresponding market power are not clear. This article uses recent data from notified mergers to show the extent of the static level of market concentration (measured using the Herfindahl–Hirschman index). This article argues that consumers and workers would benefit from additional actions to promote effective competition and inclusion in markets.

Before the pandemic, the South African economy remained stuck in low gear, with anemic growth, stagnant private investment, and a shrinking tradable sector. Subdued growth has raised unemployment, poverty, and inequality, hindering inclusion efforts. The pandemic has worsened economic and social vulnerabilities. Economic recovery and social inclusion hinge critically on structural reforms to boost competiveness and growth. Product markets represent a cornerstone of the reform strategy. Firms have used their market power to drive up prices and limit competition. Important state-owned monopolies provide low-quality services, while representing a fiscal drag. Existing regulations inhibit the entry of both domestic and foreign firms. Addressing product markets constraints could boost per capita growth by 1 percentage point—adding about 2½ percentage points to headline growth—and foster greater inclusion.

Despite what we learn in law school about the “meeting of the minds,” most contracts are merely boilerplate—take-it-or-leave-it propositions. Negotiation is nonexistent; we rely on our collective market power as consumers to regulate contracts’ content. But boilerplate imposes certain information costs because it often arrives late in the transaction and is hard to understand. If those costs get too high, then the market mechanism fails. So how high are boilerplate’s information costs? A few studies have attempted to measure them, but they all use a “horizontal” approach—i.e., they sample a single stratum of boilerplate and assume that it represents the whole transaction. Yet real-world transactions often involve multiple layers of contracts, each with its own information costs. What is needed, then, is a “vertical” analysis, a study that examines fewer contracts of any one kind but tracks all the contracts the consumer encounters, soup to nuts. This Article presents the first vertical study of boilerplate. It casts serious doubt on the market mechanism and shows that existing scholarship fails to appreciate the full scale of the information cost problem. It then offers two regulatory solutions. The first works within contract law’s unconscionability doctrine, tweaking what the parties need to prove and who bears the burden of proving it. The second, more radical solution involves forcing both sellers and consumers to confront and minimize boilerplate’s information costs—an approach I call “forced salience.” In the end, the boilerplate experience is as deep as it is wide. Our empirical work should reflect that fact, and our policy proposals should too.
