Standard economic models of tort deterrence assume that a tortfeasor's precaution set is convex — usually the non-negative real numbers, interpreted as the set of feasible levels of spending on safety. In reality, however, the precaution set is often discrete. A good example is the problem of...

Karni and Vierø (2013) propose a model of belief revision under growing awareness- reverse Bayesianism- which posits that as a person becomes aware of new acts, conse- quences, or act-consequence links, she revises her beliefs over an expanded state space in a way that preserves the relative...

Auto insurers often use credit-based insurance scores in their underwriting and rating processes. The practice is controversial — many consumer groups oppose it, and most states regulate it, in part out of concern that insurance scores proxy for policyholder income in predicting claim risk. We...

This paper studies the effects of allocation rules on the stability of mass tort class actions. I analyze a two-stage model in which a defendant faces multiple plaintiffs with heterogeneous damage claims. In stage 1, the plaintiffs play a noncooperative coalition formation game. In stage 2, the...

Standard accident models are based on the expected utility framework and represent agents' beliefs about accident risk with a probability distribution. Consequently, they do not allow for Knightian uncertainty, or ambiguity, with respect to accident risk and cannot accommodate optimism...

The paper suggests a similarity function for applications of empirical similarity theory in which the notion of similarity is asymmetric. I propose defining similarity in terms of a quasimetric. I suggest a particular quasimetric and explore the properties of the empirical similarity model given...

We build a dynamic political economy model with a two-class society, workers and the elite, in which the elite formation, the innovation rate and fiscal policy are endogenous. The model generates a mapping between institutions and patterns of growth consistent with empirical evidence. Ex ante,...
