Editing Predatory pricing (section)

===No rule===
According to Easterbrook, predatory pricing is rare and should not be considered a central concern. Introducing laws against predation, especially because it is rare, could lead to generating false positive errors, which would restrict the rule. The main point of the argument is that government intervention is dispensable, as predation is unlikely to succeed and creates a deterrent effect on its own. The deterrent effect results from selling goods and services below the costs, which causes losses without the gain in market power. In this case, the market power does not increase due to the market share holder weathering the predatory strategy. Thus, the firm punished itself by taking losses without gaining market share. As a consequence, this acts a deterrent for other firms. An additional argument against the implementation of rules is the inability of courts or competition authorities to differentiate predatory from competitive prices.<ref>Easterbrook, Predatory Strategies, supra note 1 at 264, 333-37</ref>
