Negative-expected-value (NEV) suits are ones in which the expected litigation costs exceed the expected judgment. This paper offers a new explanation for the credibility and success of plaintiff with NEV suits.

The analysis identifies the conditions under which a plaintiff with an NEV suit will have a credible threat and succeed in extracting a settlement. It is demonstrated that plaintiffs have credible threats in a much wider set of cases – including in numerous small-stake cases – than has been suggested by prior economic analysis of the subject.
