The US patent system is a foundation of our nation's economy, encouraging innovation and growth. The exclusive right to use and license an invention provides numerous benefits to its inventor and to the broader economy. The patent system is not costless, however, and significant costs stem from...

We analyze the interactions between social norms, the prevalence of regulated acts, and policies. These interactions are impacted by people's inability to directly observe actors' behavior. Norms are ineffective incentivizers when acts are committed either very frequently or very infrequently,...

Imprisonment and monetary rewards for non-convictions can similarly incentivize potential offenders to refrain from committing crime. Although imprisonment is expensive, it may still enjoy a cost advantage over rewards. This is because only detected criminals are imprisoned, whereas rewards need...

This article considers the possibility of simultaneously reducing crime, prison sentences, and the tax burden of financing the criminal justice system by introducing positive sanctions, which are benefits conferred to non-convicts. Specifically, it proposes a procedure wherein a part of the...

The literature contains ambiguous findings as to whether statistical discrimination, e.g. in the form of racial profiling, causes a reduction in deterrence. These analyses, however, assume that enforcers' incentives are exogenously fixed. This article demonstrates that when the costs and...

High recidivism rates in the United States are a well-known and disturbing problem. In this article, we explain how this problem can be mitigated in a cost-effective manner through reforms that make greater use of humane methods that help inmates rather than using more punitive measures. We...

We revisit the economic theory of exclusionary rules. First, we show that more exclusion may induce enforcers to conduct more searches, contrary to the standard notion that more exclusion leads to fewer searches. Second, we identify and investigate the complexities that arise when enforcers may...

In 1993, the Supreme Court established a new standard for the admissibility of expert evidence with its decision in Daubert v. Merrell Dow Pharmaceuticals. Although whether Daubert actually has increased the reliability of expert evidence remains an open question, empirical research generally...

We study the interactions between accuracy and standards used in the determination of legal liability. First, we show that accuracy and type-1 errors (wrongful findings of liability) must reduce each other's effectiveness in mitigating optimal type-2 errors (wrongful failures to assign...

The overruling of prior case law is one of the most dramatic events in a common-law system, and the rate of overrulings is often considered an important measure of legal change. To measure this process more precisely, and thereby elucidate the relationship between legal doctrines of stare...
