Competition law was designed for markets of the nineteenth century. The monopolies of the twenty-first century require different analytical frameworks.
What Competition Policy Was Designed For
Competition policy — the set of laws and regulatory frameworks designed to prevent the accumulation of market power that allows firms to harm consumers, restrict output, and raise prices above competitive levels — was developed in an industrial era context where the primary competition concerns were horizontal mergers between producers of physical goods and explicit price-fixing agreements among competitors. The analytical frameworks it developed — market definition, concentration ratios, consumer welfare standards — were calibrated to these concerns and work reasonably well for them.
The contemporary economy presents competition concerns that these frameworks were not designed to address. The platform economy generates network-effect monopolies that grow to dominance without the horizontal mergers or price-fixing that traditional competition policy targets. The data economy generates information asymmetries that produce competitive advantages that pricing analysis cannot fully capture. The institutional economy generates access monopolies that operate outside market structures entirely. Each of these requires analytical frameworks that traditional competition policy does not provide.
The Consumer Welfare Standard's Limitations
The consumer welfare standard — the principle that competition policy should focus on harm to consumers rather than harm to competitors — was a significant analytical advance that clarified competition policy's objectives and prevented its use to protect inefficient incumbents from more efficient new entrants. It also created a specific blind spot: the harm that market concentration causes to participants in the economy who are not consumers in the direct sense — workers, suppliers, communities, and the competitive dynamics that generate innovation over time. The low-priced dominant platform that systematically underpays its workers and suppliers while providing cheap services to consumers is harmful in ways the consumer welfare standard does not capture.
The Innovation Challenge
The most consequential limitation of contemporary competition policy is its difficulty addressing competitive harm to innovation. The merger that eliminates a potential future competitor — that acquires a nascent threat before it has become large enough to be visible in traditional market analysis — causes harm that the acquisition price does not reflect and that the consumer welfare standard at the time of merger cannot detect. The dynamic competition harm that this type of acquisition produces is only visible years later, when the market that would have been more competitive had the potential entrant survived and grown does not develop as it would have.
Competition policy is the institutional response to the economy that existed when it was designed. The economy has changed faster than the policy. The monopolies that matter most today are not the ones the frameworks were built to see.
