This paper examines the optimal use of criminal solicitation as a law enforcement strategy. The benefits are greater deterrence of crime (due to the greater likelihood of apprehension), and the savings in social harm as some offenders are diverted away from committing actual crimes through...

This paper examines factors affecting the decision of whether or not to make certain harmful acts illegal. It considers factors related both to the cost of law enforcement and to the crime commission decision. On the enforcement side, illegality is limited by the existence of fixed notice and...

We consider a government’s interrelated decisions of enacting laws prohibiting harmful behavior and choosing how aggressively to enforce those laws. There are three broad policies available to the government in this regard: not prohibiting the act at all, enacting a law and enforcing it, and...

Escalating penalties for repeat offenders are a pervasive feature of punishment schemes in various contexts, but economic theory has had a hard time rationalizing the practice. This paper reviews the literature on escalating penalties, and then develops a theory based on uncertainty on the part...

Marginal deterrence concerns the incentives created by criminal penalties for offenders to refrain from committing more harmful acts. We show that when offenders act sequentially, it is often optimal for the level of the sanction, not just the expected sanction, to rise with the severity of the...

The Fourth Amendment prohibits unreasonable searches and seizures in criminal investigations. The Supreme Court has interpreted this to require that police obtain a warrant prior to search and that illegally seized evidence be excluded from trial. A consensus has developed in the law and...

Economic models of crime and punishment implicitly assume that the government can credibly commit to the fines, sentences, and apprehension rates it has chosen. We study the government's problem when credibility is an issue. We find that several of the standard predictions of the economic model...

Debtors’ prisons have been commonplace throughout history, including in the United States. While imprisonment for debt no doubt elicited some repayment by benefactors of the debtor, we argue that its primary function was to deter default in the first place by giving borrowers an incentive to...
