Disputes over penalties for breach of contract are often solved in court. A simple model shows how inefficient courts may induce public buyers to refrain from enforcing penalties for late delivery to avoid litigation, inducing sellers to delay. Using a large dataset on Italian public...

An important action that is illegal according to competition law, both in the US and Europe, is predatory pricing. In this paper we develop a model that allows an entrant to sue an incumbent for predatory pricing. The cost of production is essential for judgments in such cases, and we allow the...

The burden of proof is a central feature of adjudication, and analogues exist in many other settings. It constitutes an important but largely unappreciated policy instrument that interacts with the level of enforcement effort and magnitude of sanctions in controlling harmful activity. Models are...

Agents may commit a crime twice. The act is inefficient so that the agents are to be deterred. Even if an agent is law abiding, she may still commit the act accidentally. The agents are wealth constrained. The government seeks to minimize the probability of apprehension. If the benefit from the...

This paper presents a model of penalties that reconciles the conflicting accounts optimal punishment by Becker, who argued penalties should internalize social costs, and Posner, who suggested penalties should completely deter offenses. The model delivers specific recommendations as to when...

Within the past decade, the EU has made significant steps in strengthening and harmonising the legal framework of capital markets. Despite passing and amending secondary legislation on this topic, it only partially addressed the issue of enforcement, leaving private enforcement an issue for its...

The paper focuses on the various methods used to quantify cartel damages, which have become more and more important as private damage suits in the aftermath of antitrust litigation increase. The approaches implementation is embedded into current legal environments with regards to the estimation...

This paper discusses the literature on the enforcement of incomplete contracts. It compares legal enforcement to enforcement via relationships and reputations. A number of mechanisms, such as the repeat purchase mechanism (Klein and Leffler (1981)) and efficiency wages (Shapiro and Stiglitz...

I consider transactions involving asymmetric prisoners dilemmas between pairs of players selected chosen from two large populations. Games are played repeatedly, but information about cheating is not adequate to sustain cooperation, and there is no official legal system of contract enforcement....

When should laws be enforced by private actors and when should society rely on law enforcement by public authorities? This question has been analyzed in great detail in law & economics scholarship. This article surveys the literature and outlines a framework of criteria for deciding whether...
