Diabetes Treatments And Moral Hazard, Jonathan Klick, Thomas Stratmann Aug 2007

Diabetes Treatments And Moral Hazard, Jonathan Klick, Thomas Stratmann

All Faculty Scholarship

In the face of rising rates of diabetes, many states have passed laws requiring health insurance plans to cover medical treatments for the disease. Although supporters of the mandates expect them to improve the health of diabetics, the mandates have the potential to generate a moral hazard to the extent that medical treatments might displace individual behavioral improvements. Another possibility is that the mandates do little to improve insurance coverage for most individuals, as previous research on benefit mandates has suggested that mandates often duplicate what plans already cover. To examine the effects of these mandates, we employ a triple-differences …


Medical Malpractice Reform And Physicians In High-Risk Specialties, Jonathan Klick, Thomas Stratmann Jun 2007

Medical Malpractice Reform And Physicians In High-Risk Specialties, Jonathan Klick, Thomas Stratmann

All Faculty Scholarship

If medical malpractice reform affects the supply of physicians, the effects will be concentrated in specialties facing high liability exposure. Many doctors are likely to be indifferent regarding reform, because their likelihood of being sued is low. This difference can be exploited to isolate the causal effect of medical malpractice reform on the supply of doctors in high-risk specialties, by using doctors in low-risk specialties as a contemporaneous within-state control group. Using this triple-differences design to control for unobserved effects that correlate with the passage of medical malpractice reform, we show that only caps on noneconomic damages have a statistically …


Risky Sexual Behavior, Testing And Hiv Treatments, Stéphane Mechoulan Jan 2007

Risky Sexual Behavior, Testing And Hiv Treatments, Stéphane Mechoulan

Stéphane Mechoulan

This paper studies the impact of antiretroviral therapies (ARVs) on HIV testing and risky sexual behavior. I use data collected in San Francisco among a high-risk population from 1994 to 2002. The evidence supports the hypothesis of a causal link between the introduction of ARVs in late 1996 and the sharp increase in risky sexual behavior that ensued. Further, following ARVs, testers take more risks while non-testers take fewer risks. The proportion of testers remains stable, which was ambiguous a priori. To the extent that ARVs may induce changes in the composition of the testing and non-testing groups, such effects …
