This paper develops an original mean-variance model able to capture the disposition of the parties towards both standard risk and ambiguity. Ambiguity arises when the causal link between conduct and harm is not univocal, as is frequently the case with toxic torts. Risk aversion and ambiguity...

This study investigates the optimal nature of law making under uncertainty. I focus on a case in which a harmful activity will be subjected to some regulatory measures (a standard, exposure to liability, or a corrective tax). The benefits and costs of precaution are ex-ante uncertain, and this...

This article compares the classic liability rules, negligence and strict liability, under the hypothesis that injurers and victims formulate subjective beliefs about the probabilities of harm. Parties may reasonably disagree in their assessment of the precautionary measures available: a measure...

This paper develops an original mean-variance model able to capture the disposition of the parties towards both standard risk and ambiguity. Ambiguity arises when the causal link between conduct and harm is not univocal, as is frequently the case with toxic torts. Risk aversion and ambiguity...

This paper investigates the case in which the benefits and the costs of prevention are subject to uncertainty. Prevention measures are taken after uncertainty has unraveled. The conventional policy prescribes that prevention measures are taken up to the point in which the realized marginal cost...

This paper investigates the ability of liability rules to allocate uncertainty. Uncertainty includes both the standard risk and the ambiguity that arises when the causal link between conduct and harm is not conclusive, as is frequently the case with toxic torts. The optimal features of the...
