Attitudes of conformity can be understood as a product of adaptation. Existing models of conformity invoke preference falsification with individuals hiding their true preferences. We posit an adaptive mechanism for conformity. Because non-conformity leads to costs as a dissenting individual is...

Single-firm event studies play an important role in both scholarship and litigation despite the general invalidity of standard inference. We use a broad cross-section of 2000--2007 CRSP data and find that the standard approach performs poorly in terms of both Type I and Type II error rates. We...

Economic theory predicts that abortion laws affect sexual behavior since they change the marginal cost of having risky sex. We estimate the impact of abortion laws on sexual behavior by reported gonorrhea incidence. Our data panel includes 41 countries for which consistent gonorrhea data are...

In the law enforcement literature there is a presumption—supported by some experimental and econometric evidence—that criminals are more responsive to increases in the certainty than the severity of punishment. Under a general set of assumptions, this implies that criminals are risk seeking....

This paper reviews the existing law and economics literature on crime, noting where various models might apply to the terror context. Specifically, it focuses on two strands of the literature, deterrence and incapacitation. It considers anti-terror measures enacted by different countries,...

A model of addiction in which individuals are forward looking implies that as the availability of addiction treatment options grows, individuals will consume more of an addictive good. We test this implication using cross-state variation in the adoption of mental health parity mandates that...

The health benefits of spas have been hypothesized for centuries. If this hypothesis is correct, spa therapy offers a low cost alternative to more expensive and potentially more invasive medical treatments for ailments such as back pain and arthritis. We use individual-level panel data to...

Many states have passed laws mandating insurance companies to provide or offer some form of mental health benefits. These laws presumably lower the price of obtaining mental health services for many adults, and as a result, might improve health outcomes. This paper analyzes the effectiveness of...
