Abstract

In this chapter, we address a number of foundational questions. What exactly are platforms? How do platforms relate to the various types of network effects? Importantly, do we need different tools to assess potential anticompetitive conduct that involves platforms?

Specifically, we begin with a discussion of the various types of network effects, as these effects are integral to understanding the nature of platforms. Next, we consider platforms more from the perspective of incentives rather than an overt focus on a standardized definition. We also discuss how platforms compete, including discussions of “zero-price” markets and the associated idea of “attention” markets. Finally, we offer some guidance on some relevant economic issues to consider when assessing platform markets in the context of antitrust cases.

数字市场中的网络效应和平台概述
在本章中,我们将讨论一些基本问题。平台到底是什么?平台如何与各种类型的网络效应相关联?重要的是,我们是否需要不同的工具来评估涉及平台的潜在反竞争行为?具体来说,我们首先讨论各种类型的网络效应,因为这些效应对于理解平台的本质是不可或缺的。其次,我们更多地从激励的角度来考虑平台,而不是公开地关注标准化的定义。我们还讨论了平台如何竞争,包括讨论“零价格”市场和相关的“注意力”市场。最后,我们就在反垄断案件背景下评估平台市场时需要考虑的一些相关经济问题提供了一些指导。
