Arlen on Economic Analysis of Tort Liability

Jennifer Arlen has posted to SSRN Economic Analysis of Tort Liability for an Imperfect World.  The abstract provides:

Tort liability generally is not justified by the presence of risk-producing activities alone. It tends to be justified by the combination of risk-producing activities and information costs that impede alternative solutions, such as private contracting or ex ante regulation. The observation that tort liability is justified by information costs impacts economic analysis of tort liability. It highlights that economic analysis of optimal tort rules should employ economic models where information is costly. In addition, it reveals the goals of optimal tort liability often should include providing optimal incentives to risk-imposers and others to invest in information needed to identify and provide optimal level of care. This chapter presents economic analysis of optimal tort liability focusing on the use of liability where information is costly. It shows that incorporating endogenous costly information alters tort liability’s optimal structure and incentive effects, both as applied to individual injurers and risk-imposers operating within organizations.
