We analyze the interactions between social norms, the prevalence of regulated acts, and policies. These interactions are impacted by people's inability to directly observe actors' behavior. Norms are ineffective incentivizers when acts are committed either very frequently or very infrequently,...

We study the problem of deterring undesirable behavior in a moral hazard framework with risk averse individuals, noisy information and costly sanctions. We find that, if sanctions are a pure loss, a utilitarian society should use a bang-bang penalty scheme satisfying the maximum penalty...

This paper analyzes the incentive properties of the standard and burden of proof for a finding of negligence, when evidence about injurers' behavior is imperfect and rests with the parties. We show that the `preponderance of evidence' standard used in common law, together with ordinary exclusion...

I examine the case where fulfillment of a contractual commitment is only imperfectly verifiable and ask whether the court should then tell the truth regarding the action in dispute. I show that truth seeking does not maximize the expected surplus from contractual relationships. From the parties'...

Cet article analyse la désirabilité sociale de l'assurance de responsabilité lorsque les comportements de prévention sont imparfaitement observables. On sait que l'assurance de responsabilité est socialement avantageuse en responsabilité sans faute, même s'il y a aléa moral et que...

We consider situations where legal liability yields insufficient incentives for socially efficient behavior, e.g., individuals who cause harm are not always sued or are unable to pay fully for harm done. Some individuals nevertheless behave efficiently because of intrinsic prosocial concerns....

This paper analyses whether liability insurance is socially desirable, under strict liability or under the negligence rule, when the injurer?s behavior is imperfectly observable. Liability insurance is known to be socially beneficial under the strict liability rule, even though it can reduce...

We analyze the design of legal principles and procedures for court decision-making in civil litigation. The objective is the provision of appropriate incentives for potential tort-feasors to exert care, when evidence about care is imperfect and may be distorted by the parties. Efficiency is...

We argue that the common-law standard of proof, given the rulesof evidence, does not minimize expected error as usually argued inthe legal literature, but may well be e±cient from the standpointof providing maximal incentives for socially desirable behavior.By contrast, civil law's higher but...
