We formally analyze the effects of legal presumptions in patent litigation. We set up a novel contest model to study litigation outcomes, judgement errors, and resource dissipation under three alternative presumption criteria: a presumption that the patent is valid; a presumption that the patent...

Juries are a fundamental element of the criminal justice system. In this paper, we model jury decision-making as a function of three institutional variables: jury size, voting requirement, and the applicable standard of proof. Changes in jury size, voting requirements, and standards of proof...

This paper is about the incentive effects of legal presumptions. We analyze three interrelated effects of legal presumptions in a tort setting: (1) incentives to invest in evidence technology; (2) incentives to invest in care-type precautions; and (3) incentives to mitigate excessive activity...

In negligence regimes, tort plaintiffs traditionally bear the burden of proving the negligence of their defendants. Several European legal systems adopted rules that have reversed this traditional evidentiary rule in certain categories of torts, creating a rebuttable presumption of negligence...

This chapter provides an overview of the application of experimental methods to three topics in law and economics: bargaining and the Coase theorem; pre-trial settlement and the litigation process; torts and liability rules. These research areas serve as examples of how economics experiments can...

This paper analyzes deterrence, settlement, and litigation spending under two alternative procedural regimes, i.e., the adversarial versus inquisitorial systems. We present a general litigation model with three sequential stages---care, settlement, and litigation stages---and we test the...
