This paper develops a simple spatial model of fund-raising, in which charities select a target population to solicit donations. First, we show that in a competitive charity market without any intervention, the number of charities in the market and/or the overall net funds raised by charities may...

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 a criminal trial, a jury may observe characteristics about the defendant (or victim) and use them to form a belief on the likelihood of guilt. Many evidentiary rules attempt to limit this inference. If jury beliefs are rational, such rules may be counterproductive. Any prohibition on the use...

We derive a profit maximizing legislator's decisions to criminalize and punish offenses, and compare them to the optimal scope of criminalization and punishment. A profit maximizing legislator overcriminalizes and overpunishes all criminalized acts when the degree to which it internalizes harms...

This article presents a model wherein law enforcers propose sentences to maximize their likelihood of reelection, and shows that elections typically generate over-incarceration, i.e., longer than optimal sentences. It then studies the effects of disenfranchisement laws, which prohibit convicted...

The doctrine of duress allows a party to a contract to avoid its contractual obligations when it was induced to enter that contract by a wrongful threat while in a dire position that leaves it no choice but to enter the contract. Although threats of criminal or tortious conduct clearly are...

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...

A defendant who admits to having committed an offense may nevertheless be acquitted if he can provide a legally cognizable justification or excuse for his actions by raising an affirmative defense. This article explains how affirmative defenses generate social benefits in the form of avoided...

Preventive law enforcement increases social welfare by hindering the infliction of criminal harm, but produces inconvenience costs to the general public, because it requires interfering with the acts of innocents as well as attempters. This article shows that the optimal amount of investment in...
