This paper integrates the literatures on the social value of lawsuits, the evolution of the law, and judicial preferences to evaluate the hypothesis that the law evolves toward efficiency. The setting is a simple accident model with costly litigation where the efficient law minimizes the sum of...

The private value of lawsuits is based on plaintiffs' expected recovery at trial compared to their filing costs, whereas the social value consists of the incentives suits create for injurers to invest in accident avoidance. Generally, there is no relationship between these two values: there may...

This paper re-examines the social versus private value of lawsuits when both injurers and victims can take care. The basic conclusions of that literature remain valid in this context: the private and social values generally differ, and there is no necessary relationship between them, meaning...

This paper embeds a model of lawmaking in an equilibrium framework in which the demand for trials is rationed by court delay. The lawmaking process depends on a combination of selective litigation, judicial bias, and precedent. The steady state equilibrium of the model determines both the length...

The claim that the common law displays an economic logic is a centerpiece of the positive economic theory of law. A key question in this literature is whether this outcome is due to the conscious efforts of judges, or the result of invisible hand processes. This paper develops a model in which...

Criminal procedure concerns the rules regarding the treatment of criminal defendants during the time from their arrest until the determination of a final verdict. From an economic perspective, the goal of this process is to achieve the most accurate determination of guilt at the lowest possible...

Greater trial delay is commonly associated with decreasing demand for trials, thereby bringing about an equilibrium for a given trial capacity. This note highlights that – in contrast to this premise – trial delay may in fact increase trial demand. Such an outcome is established for a...

Under the standard economic model of torts, punitive damages correct for imperfect detection. Incorporating litigation costs into the model provides a justification for punitive damage caps. At the optimum, caps balance deterrence against the cost of litigation. Empirical testing of the model is...

Law and economics scholars argue that the common law evolves toward efficiency. Invisible hand theories suggest that the law is primarily driven by a selection process whereby inefficient laws are litigated more frequently than efficient laws, and hence are more likely to be overturned. But the...

This paper compares the all-or-nothing and proportionate damage rules for allocating damages in tort cases under evidentiary uncertainty. The focus is on how the two rules affect litigation expenditures by plaintiffs and defendants. The results of simulation experiments show that the expected...
