Why this is mistaken
Structure organizes assumptions and likely mechanisms. It does not mechanically produce one conduct or outcome. Product differentiation, entry, information, capacity, contracts, regulation, buyer power, external effects, strategy, and time can change results within a broad label.
Repair the claim by defining the market, listing the model assumptions actually supported, identifying the mechanism that links structure to the proposed outcome, testing rival explanations, and keeping economic, accounting, and legal conclusions separate.
Where to watch
When this mistake may appear
