The Welfare Effects of Medical Malpractice Liability
Policymakers and the public are concerned about the role of medical malpractice liability in the rising cost of medical care. We use variation in the generosity of local juries to identify the causal impact of malpractice liability on medical costs, mortality, and social welfare. The effect of malpractice on medical costs is large relative to its share of medical expenditures, but relatively modest in absolute terms—growth in malpractice payments over the last decade and a half contributed at most 5.0% to the total real growth in medical expenditures, which topped 33% over this period. On the other side of the ledger, malpractice liability leads to modest reductions in patient mortality; the value of these more than likely exceeds the cost impacts of malpractice liability. Therefore, policies that reduce expected malpractice costs are unlikely to have a major impact on health care spending for the average patient, and are also unlikely to be cost-effective over conventionally accepted ranges for the value of a statistical life.

Private Information, Self-Serving Biases, and Optimal Settlement Mechanisms: Theory and Evidence
The law and economics literature on suit and settlement has tended to focus on two alternative conceptual models. On the one hand, the optimism model of pre-trial negotiation attempts to explain settlement failure as an artifact of unfounded optimism by one or both parties. The idea that bargaining agents can adopt such non-rational biases receives support from experimental evidence. On the other hand, the private information model of pre-trial bargaining portrays settlement failures as an artifact of strategic information rent extraction. It finds support in some experimental evidence as well. This paper presents (for the first time) a mechanism-design approach for studying suit and settlement in the presence of both optimism and two-sided private information. We use a parameterization of our framework to generate testable comparative statics that distinguish between the two competing models, and then test these predictions using data from civil jury trials before and after the limitation on non-economic medical malpractice damages introduced by California legislation during the 1970s. Our (preliminary) results appear to be most consistent with the optimism model rather than the information model
Trends and disparities in the utilization of influenza vaccines among commercially insured US adults during the COVID-19 pandemic
OBJECTIVES: Little is known about how the coronavirus disease 2019 (COVID-19) pandemic affected influenza vaccine utilization and disparities. We sought to estimate changes in the likelihood of receiving an influenza vaccine across different demographic subgroups during the COVID-19 pandemic. METHODS: In this cohort study, we analyzed influenza vaccine uptake from 2019 to 2020 using Optum commercial insurance claims data. Eligible individuals were aged 18 or above in 2018 and continuously enrolled from 08/01/2018 through 12/31/2020. Multivariable logistic regressions were fitted for the individual-level influenza vaccine uptake. Adjusting for demographic factors and medical histories, we estimated probabilities of receiving influenza vaccines before and after the COVID-19 pandemic across demographic subgroups. RESULTS: From August to December 2019, unadjusted influenza vaccination rate was 42.3%, while in the same period of 2020, the vaccination rate increased to 45.9%. Females had a higher vaccination rate in 2019 (OR: 1.16, 95% CI 1.15-1.16), but the increase was larger for males. Blacks and Hispanics had lower vaccination rates relative to whites in both flu seasons. Hispanics showed a greater increase in vaccination rate, increasing by 7.8 percentage points (p \u3c .001) compared to 4.4 (p \u3c .001) for whites. The vaccination rate for Blacks increased by 5.2 percentage points (p \u3c .001). All income groups experienced vaccination improvements, but poorer individuals had lower vaccination rates in both seasons. The most profound disparities occurred when educational cohort were considered. The vaccination rate increased among college-educated enrollees by 8.8 percentage points (p \u3c .001) during the pandemic compared to an increase of 2.8 percentage points (p \u3c .001) for enrollees with less than a 12th grade education. Past influenza infections or vaccination increased the likelihood of vaccination (p \u3c .001). CONCLUSIONS: The COVID-19 pandemic was associated with increased influenza vaccine utilization. Disparities persisted but narrowed with respect to gender and race but worsened with respect to income and educational attainment

Physician spending and subsequent risk of malpractice claims: observational study
Study question Is a higher use of resources by physicians associated with a reduced risk of malpractice claims? Methods: Using data on nearly all admissions to acute care hospitals in Florida during 2000-09 linked to malpractice history of the attending physician, this study investigated whether physicians in seven specialties with higher average hospital charges in a year were less likely to face an allegation of malpractice in the following year, adjusting for patient characteristics, comorbidities, and diagnosis. To provide clinical context, the study focused on obstetrics, where the choice of caesarean deliveries are suggested to be influenced by defensive medicine, and whether obstetricians with higher adjusted caesarean rates in a year had fewer alleged malpractice incidents the following year. Study answer and limitations The data included 24 637 physicians, 154 725 physician years, and 18 352 391 hospital admissions; 4342 malpractice claims were made against physicians (2.8% per physician year). Across specialties, greater average spending by physicians was associated with reduced risk of incurring a malpractice claim. For example, among internists, the probability of experiencing an alleged malpractice incident in the following year ranged from 1.5% (95% confidence interval 1.2% to 1.7%) in the bottom spending fifth (39 379 per hospital admission). In six of the specialties, a greater use of resources was associated with statistically significantly lower subsequent rates of alleged malpractice incidents. A principal limitation of this study is that information on illness severity was lacking. It is also uncertain whether higher spending is defensively motivated. What this study adds Within specialty and after adjustment for patient characteristics, higher resource use by physicians is associated with fewer malpractice claims.
