Negative expected value suits

"Abstract:We review the literature on negative-expected-value suits (NEV suits)--suits in which the plaintiff would obtain a negative expected return from pursuing the suit all the way to judgment. We discuss alternative theories as to why, and when, plaintiffs with NEV suits can extract a positive settlement amount. In particular, we explain how such a plaintiff can extract a positive settlement due (i) asymmetry of information between the parties, (ii) divisibility of the plaintiff's litigation costs, (iii) upfront costs that the defendant must incur before the plaintiff incurs any costs; (iv) expectation that the arrival of information during the course of the litigation may turn the suit into a positive-expected-value one, (5) reputation that enables the plaintiff to bind itself to going to trial if the defendant refuses to settle; or (6) the plaintiff's having a contingency fee or retainerarrangement with its lawyer"--John M.
