Reforms to the Joint and Several Liability rule (JSL) are one of the most common tort reforms and have been implemented by most US states. JSL allows plaintiffs to claim full recovery from one of the defendants, even if that defendant is only partially responsible for the tort. We develop a...

We examine the impact of tort reforms using U.S. birth records for 1989-2001. We make four contributions: First, we develop a model that analyzes the incentives created by specific tort reforms. Second, we assemble new data on tort reform. Third, we examine a range of outcomes. Finally, we allow...

We study response behavior of New York City parking-ticket recipients by analyzing administrative data on 6.6 million tickets issued to 2 million individuals over two years. Exploiting variation (from a policy change and a field experiment) in letters sent to recipients, we find that forgetting...

This article investigates the determinants of the blockbuster punitive damages awards of at least $100 million. As of the end of 2008, there had been 100 such awards with an average value of $3.0 billion. The U.S. Supreme Court decision in State Farm v. Campbell suggested a single digit upper...

The controversies surrounding gun control policies have recently moved to the forefront of public's attention in the United States and elsewhere. Since 2005, eighteen states in the United States have passed laws extending the right to self-defense with no duty to retreat to any place a person...

From 2000 to 2010, more than 20 states passed laws that make it easier to use lethal force in self-defense. Elements of these laws include removing the duty to retreat in places outside of one's home, adding a presumption of reasonable belief of imminent harm, and removing civil liability for...

The efficiency of common law rules is central to achieving efficient resource allocation in a market economy. While many theories suggest reasons why judge-made law should tend toward efficient rules, the question whether the common law actually does converge in commercial areas has remained...

In this essay, we discuss empirical research on the economic effects of the civil justice system. We discuss research on the effects of three substantive bodies of law- contracts, torts, and property- and research on the effects of the litigation process. We begin with a review of studies of...

An important question in the economic study of enforcement is the appropriate, and the actual, division of responsibilities between public and private enforcers. This question has been brought into sharp focus recently by an article in which Gary Becker and George Stigler advocate the...

Regression discontinuity designs (RDDs) are a popular method to estimate treatment effects. However, RDDs may fail to yield consistent estimates if the forcing variable can be manipulated by the agent. In this paper, we examine one interesting set of economic models with such a feature....
