Antitrust cases, including recent complaints filed against dominant technology platforms, have alleged conduct that harms innovation.

The article briefly reviews the economics literature relating the effects of market power on innovation incentives and identifies circumstances in which structural conditions warrant a presumption that anticompetitive conduct by a dominant firm is likely to harm or promote innovation.
