鲍莫尔、威利格和其他“可持续性”理论的倡导者继续敦促这一想法，不仅因为它的洞察力，而且还因为它是许多反垄断和监管决策的明确基础。然而，该理论的局限性仍然存在。这三个关键假设极为严格，其中两个相互冲突。这个理论对不完善的地方并不可靠。为了用稳定性取代有效竞争，鲍莫尔必须采用一系列令人难以置信的命题，不幸的是，这些命题几乎没有分析或经验基础。
Baumol, Willig, and other advocates of "contestability" theory continue to urge the idea not only for its insights but also as a clear basis for many antitrust and regulatory decisions. Yet the limits of the theory remain. The three key assumptions are extremely strict, and two of them are in mutual conflict. The theory is not robust to imperfections. In order to displace effective competition with contestability, Baumol must adopt a sequence of implausible propositions which, unfortunately, have little analytical or empirical basis.
