The “Moligopoly” Hypothesis
Keyword(s):
This chapter examines the empirical validity of the moligopoly hypothesis—that is, the intuition that big tech monopolies are exposed to oligopoly competition across markets. The focus is on big tech firms’ annual filings to financial regulators as well as business analysts’ reports, market research and competitive intelligence. The data calls attention to the possibility of latent and complementary levels of competition in big tech that antitrust and regulatory decision-makers miss in their assessments of monopoly power in digital markets. This competition does not seem to originate from substitute products or services. And it seems to vary at firm level, suggesting significant heterogeneity amongst big tech firms.
