Risk-Risk Tradeoffs For Mass Shootings And International Terrorism, W. Kip Viscusi, Rachel Dalafave

Vanderbilt Law School Faculty Publications

This article elicits information about risk perceptions and risk–risk tradeoffs for mass shootings and international terrorist attacks. These prominent public risks are similar in many respects in that both involve traumatic injuries. One might expect that the risk–risk tradeoff rate would be 1.0 unless other attributes of these risks are pertinent. Estimates based on an original survey structured to test rates of tradeoff between deaths from these risks indicate that respondents consistently place a premium on reducing mass shooting risks, as compared to risks of international terrorism. The average premium is relatively stable even after accounting for the effect of …

Employment Practices Liability Insurance And Ex Post Moral Hazard, Joni Hersch, Erin E. Meyers

Vanderbilt Law School Faculty Publications

Many businesses purchase Employment Practices Liability Insurance (EPLI), a form of insurance that protects them from claims of discrimination, harassment, retaliation, and wrongful termination. But critics of EPLI argue that allowing insurance coverage for employment liability detracts from employment law's goal of deterrence and from notions of justice. We assess the validity of these criticisms by examining the nature of employment law claims and by reviewing characteristics of the current EPLI market. We find that past critiques miss the mark in diagnosing EPLI's major problem.

The EPLI market, for the most part, functions in a way that poses little to …

Reducing Medical Malpractice Loss Reserve Volatility Through Tort Reform, W. Kip Viscusi, Patricia H. Born, Evan M. Eastman

Vanderbilt Law School Faculty Publications

This study examines how tort reform affects uncertainty in insurance markets by testing whether noneconomic damage caps influence reserving volatility for medical malpractice insurers. Using a panel of insurers from 1986 to 2009, we estimate the determinants of loss reserve error volatility and focus on how this volatility is influenced by the percent of premiums an insurer writes that are subject to noneconomic damage caps. We find empirical evidence that tort reform reduces reserve volatility over the subsequent 3- and 5-year periods, consistent with tort reform improving insurers’ loss forecasting ability. Our findings address outcomes of tort reform that are …

Identifying The Legitimate Role Of The Value Of A Statistical Life In Legal Contexts, W. Kip Viscusi

Vanderbilt Law School Faculty Publications

This article is based on my keynote address at the American Academy of Economic and Financial Experts conference in which I examined some of the implications for legal contexts of my book, Pricing Lives: Guideposts for a Safer Society. The value of a statistical life (VSL) provides an economic measure of the efficient cost-risk tradeoff rate for mortality risk decisions. Consequently, the VSL is well suited to serving as a measure of the benefits of mortality risk reduction for government regulatory policies and for corporate risk decisions. The tort liability counterpart of this function is using the VSL to assess …

The Income Elasticity Of Global Values Of A Statistical Life: Stated Preference Evidence, W. Kip Viscusi, Clayton J. Masterman

Vanderbilt Law School Faculty Publications

Countries throughout the world use estimates of the value of a statistical life (VSL) to monetize fatality risks in benefit-cost analyses. However, the vast majority of countries lack reliable revealed preference or stated preference estimates of the VSL. This article proposes that the best way to calculate a population-average VSL for countries with insufficient or unreliable data is to transfer a base VSL from the United States calculated using labor market estimates from Census of Fatal Occupational Injuries data, coupled with adjustments for differences in income between the United States and the country of interest. This approach requires estimation of …

Pricing Lives: International Guideposts For Safety, W. Kip Viscusi

Vanderbilt Law School Faculty Publications

Government agencies throughout the world use the value of a statistical life (VSL) to monetise the mortality risk reduction benefits of government policies. The most reliable empirical estimates of the VSL using US labour market data are about US$10 million (year 2015 US dollars). Based on international estimates of the income elasticity of the VSL, one can transfer these values to other countries, leading to my VSL estimate for Australia of US$7.9 million, or A$10.0 million, which is over double the current Australia best-practices value. Transferring US VSL estimates to other nations after accounting for income differences will boost global …

Insurance Coverage Policies For Pharmacogenomic And Multi-Gene Testing For Cancer, Ellen Wright Clayton, Christine Y. Lu, Stephanie Loomer, Et Al.

Vanderbilt Law School Faculty Publications

Abstract: Insurance coverage policies are a major determinant of patient access to genomic tests. The objective of this study was to examine differences in coverage policies for guideline-recommended pharmacogenomic tests that inform cancer treatment. We analyzed coverage policies from eight Medicare contractors and 10 private payers for 23 biomarkers (e.g., HER2 and EGFR) and multi-gene tests. We extracted policy coverage and criteria, prior authorization requirements, and an evidence basis for coverage. We reviewed professional society guidelines and their recommendations for use of pharmacogenomic tests. Coverage for KRAS, EGFR, and BRAF tests were common across Medicare contractors and private payers, but …

Health Insurance Mandates, Mammography, And Breast Cancer Diagnoses, Christopher K. Carpenter, Marianne P. Bitler

Vanderbilt Law School Faculty Publications

We examine the effects of state health insurance mandates requiring coverage of screening mammograms. We find evidence that mammography mandates significantly increased mammography screenings by 4.5-25 percent. Effects are larger for women with less than a high school degree in states that ban deductibles, a policy similar to a provision of federal health reform that eliminates cost-sharing for preventive care. We also find that mandates increased detection of early stage in-situ precancers. Finally, we find a substantial proportion of the increased screenings were attributable to mandates that are not consistent with 2014 recommendations of the American Cancer Society.

Assessing The Insurance Role Of Tort Liability After Calabresi, W. Kip Viscusi, Joni Hersch

Vanderbilt Law School Faculty Publications

Calabresi’s theory of tort liability (1961) as a risk distribution mechanism established insurance as an objective of tort liability. Calabresi’s risk-spreading concept of tort has provided the impetus for much of the subsequent development of tort liability doctrine, including risk-utility analysis and strict liability. Calabresi’s analysis remains a powerful basis for modern tort liability. However, high transactions costs, correlated risks, catastrophic losses, mass toxic torts, shifts in liability rules over time, noneconomic damages, and punitive damages affect the functioning of tort liability as an insurance mechanism. Despite some limitations of tort liability as insurance, tort compensation serves both a compensatory …

The Benefits Of Mortality Risk Reduction: Happiness Surveys Vs. The Value Of A Statistical Life, W. Kip Viscusi

Vanderbilt Law School Faculty Publications

A principal component of many benefit-cost analyses (BCAs) of health, safety, and environmental regulations is the valuation of the fatality risk effects of the underlying policy. Government agencies currently value these expected effects using estimates of the value of a statistical life (VSL), that is, the tradeoff rate between money and very small risks of death. This measure corresponds to BCA's theoretically appropriate benefits measure, which is society's willingness to pay for the risk reduction. Here, I will review the VSL approach, compare it to suggested alternatives that use happiness measures of well-being, and address some of the misunderstandings that …

What’S To Know? Puzzles In The Literature On The Value Of Statistical Life, W. Kip Viscusi

Vanderbilt Law School Faculty Publications

Notwithstanding the general acceptance of the value of statistical life (VSL) estimates for policy assessment purposes, several important unresolved issues remain. First, the results from revealed preference studies are systematically higher than those from stated preference studies, potentially limiting the usefulness of stated preference studies in generalizing the VSL estimates to different populations and kinds of risks. Second, extrapolating the results of meta-analyses to project the VSL for different population groups requires that such generalization be reflective of the underlying economic content of what average VSL estimates reflect. Third, government agencies within and across countries place differing emphasis on types …

The Effects Of Tort Reform On Medical Malpractice Insurers’ Ultimate Losses, W. Kip Viscusi, Patricia Born, Tom Baker

Vanderbilt Law School Faculty Publications

Whereas the literature evaluating the effect of tort reforms has focused on the impact of reforms on insurers' reported incurred losses, this article examines the ultimate effects of reforms using the developed losses from a comprehensive sample of insurers writing medical malpractice insurance from 1984 to 2003. Noneconomic damages caps are particularly influential in reducing medical malpractice losses and increasing insurer profitability. The long-run effects of these reforms are greater than insurers' expected effects; for example, 5- and 7-year developed loss ratios are below the initially reported incurred loss ratios for those years following the enactment of noneconomic damages caps. …

Rational Discounting For Regulatory Analysis, W. Kip Viscusi

Vanderbilt Law School Faculty Publications

This Article examines the economic basis for what is termed "rational discounting," which entails full recognition of policy effects over time and exponential discounting at a riskless rate of return. Policies often cannot be ranked unambiguously in terms of their present or future orientation. Both failure to discount and preferential intergenerational discounting generate inconsistencies and economic anomalies. Office of Management and Budget (OMB) discounting guidelines now stipulate more reasonable discount rates than earlier guidelines, but err in permitting open-ended preferential rates for intergenerational effects. This Article presents a methodology for monetizing the value of statistical life for people of different …

Insurers, Illusions Of Judgment & Litigation, Chris Guthrie, Jeffrey J. Rachlinski

Vanderbilt Law School Faculty Publications

Insurers play a critical role in the civil justice system. By providing liability insurance to parties who would otherwise be untenable as defendants, insurers make litigation possible. Once litigation materializes, insurers provide representation, pay legal fees, and often play a central role in resolving disputes through settlement or adjudication. In this paper, we explore empirically how these key litigation players make important decisions in the litigation process, like evaluating a case, deciding whether to settle, and if so, on what terms. We find that insurers, though not entirely immune to the effects of cognitive illusions that have been shown to …

Natural Disaster Risks: An Introduction, W. Kip Viscusi

Vanderbilt Law School Faculty Publications

An introduction to a special issue of the Journal of Risk and Uncertainty dealing with the implications of catastrophic events for research on risk and uncertainty. What are the consequences of natural disasters? How do individuals and firms respond to such disasters? How do insurers respond, and how should the government respond? Several of these papers will have a strong normative component as they will suggest what actions individuals, firms, and the government should take in anticipation of natural disasters.

The Catastrophic Effects Of Natural Disasters On Insurance Markets, W. Kip Viscusi, Patricia Born

Vanderbilt Law School Faculty Publications

Natural catastrophes often have catastrophic risks on insurance companies as well as on the insured. Using a very large dataset on homeowners insurance coverage by state, by firm, and by year for the 1984 to 2004 period, this paper documents the positive effect on losses and loss ratios of both unexpected catastrophes as well as large events that the authors term "blockbuster catastrophes." Insurers adapt to these catastrophic risks by raising insurance rates, leading to lower loss ratios after the catastrophic event. There is a widespread event of unexpected catastrophes and blockbuster catastrophes that reduces total premiums earned in the …

The Denominator Blindness Effect: Accident Frequencies And The Misjudgment Of Recklessness, W. Kip Viscusi

Vanderbilt Law School Faculty Publications

People seriously misjudge accident risks because they routinely neglect relevant information about exposure. Such risk judgments affect both personal and public policy decisions, e.g., choice of a transport mode, but also play a vital role in legal determinations, such as assessments of recklessness. Experimental evidence for a sample of 422 jury-eligible adults indicates that people incorporate information on the number of accidents, which is the numerator of the risk frequency calculation. However, they appear blind to information on exposure, such as the scale of a firm's operations, which is the risk frequency denominator. Hence, the actual observed accident frequency of …

The Value Of A Statistical Life: A Critical Review Of Market Estimates Throughout The World, W. Kip Viscusi, Joseph E. Aldy

Vanderbilt Law School Faculty Publications

A substantial literature over the past thirty years has evaluated tradeoffs between money and fatality risks. These values in turn serve as estimates of the value of a statistical life. This article reviews more than 60 studies of mortality risk premiums from ten countries and approximately 40 studies that present estimates of injury risk premiums. This critical review examines a variety of econometric issues, the role of unionization in risk premiums, and the effects of age on the value of a statistical life. Our meta-analysis indicates an income elasticity of the value of a statistical life from about 0.5 to …

The Value Of Life In Legal Contexts: Survey And Critique, W. Kip Viscusi

Vanderbilt Law School Faculty Publications

Value of life issues traditionally pertain to insurance of the losses of accident victims, for which replacement of the economic loss is often an appropriate concept. Deterrence measures of the value of life focus on risk-money tradeoffs involving small changes in risk. Using market data for risky jobs and product risk contexts often yields substantial estimates of the value of life in the range of $3 million to $9 million. These estimates are useful in providing guidance for regulatory policy and assessments of liability. However, use of these values to determine compensation, known as hedonic damages, leads to excessive insurance.

The Governmental Composition Of The Insurance Costs Of Smoking, W. Kip Viscusi

Vanderbilt Law School Faculty Publications

The estimated health risks from smoking have significant external financial consequences for society. Studies at the national level indicate that cigarettes are self-financing since external costs such as those due to illnesses are offset by cost savings associated with premature death, chiefly pension costs. This paper extends this analysis to all 50 states and considers the costs considered in the state attorneys general suits against the cigarette industry. Cigarettes are always self-financing from the standpoint of costs to each state. The extent of the cost savings is less than at the federal level. However, smokers' higher medical costs are outweighed …

Medical Malpractice Insurance In The Wake Of Liability Reform, W. Kip Viscusi, Patricia Born

Vanderbilt Law School Faculty Publications

This article examines the effect of the liability reforms on medical malpractice insurance over the 1984-91 period. This is the first study to use data by firm and by state for every firm writing medical malpractice insurance over that time period. The liability reforms increased insurance profitability (that is, decreased the loss ratios), where the main mechanism of influence was through decreasing losses. The quantile regression estimates imply that the greatest effects of liability reform are on the most unprofitable firms and that the effect is not uniform across the entire market. This pattern is consistent with the other principal …

The National Implications Of Liability Reforms For General Liability And Medical Malpractice Insurance, W. Kip Viscusi, Patricia Born

Vanderbilt Law School Faculty Publications

The stabilization of the insurance market may lead to lower prices for products and for medical care, but will also generally lead to lower values of tort awards as well. If the social objective was simply to reduce losses, then that objective could be achieved by abolishing tort liability altogether. Our societal concerns are clearly much broader. In the absence of a more detailed assessment of the desirability of the reforms and their effect on injured parties, it would be premature to conclude that reform efforts that were successful in enhancing insurance market profitability should be judged a success from …

Equivalent Frames Of Reference For Judging Risk Regulation Policies, W. Kip Viscusi

Vanderbilt Law School Faculty Publications

Although the design of risk regulations has not yet attained what might be termed the economist's ideal of maximizing the difference between benefits and costs, substantial progress has been made in the design of regulatory policy. When the risk regulation agencies began their efforts in the early 1970s, there was widespread concern that something needed to be done to address the important risks that society faces. The substantial optimism with respect to our technological capabilities in reducing risk may have led to a failure to recognize the limits of our risk regulation ventures. Over time, there has been increasing emphasis …

The Dimensions Of The Product Liability Crisis, W. Kip Viscusi

Vanderbilt Law School Faculty Publications

Examination of a variety of sources of statistics indicates that the product liability crisis is real, and it is not simply imagined or contrived by the insurance industry. Litigation in the product liability area has escalated dramatically, but to some extent the industry was able to mute the effect of this escalation because of the influence of rising interest rates in the early 1980s as well as because the shrinking market for product liability insurance masked much of the explosion that was occurring in terms of the costs of product liability coverage. The dominant pattern in the early 1980s was …

The Performance Of Liability Insurance In States With Different Products-Liability Statutes, W. Kip Viscusi

Vanderbilt Law School Faculty Publications

The liability crisis of the mid-1980s has led to an extensive reexamination of the liability system. A number of explanations have been offered for the substantial increase in insurance premiums and, in some cases, a decline in the availability of insurance. These include stimulation of the underwriting cycle by a decline in interest rates, collusion among insurance firms, rising tort costs, and uncertainty with respect to the liability burden.' Most observers, however, also point to changes in tort law itself. For example, plaintiffs may now have a more favorable environment for obtaining an award and, if they are successful, they …

The Determinants Of The Disposition Of Product Liability Claims And Compensation For Bodily Injury, W. Kip Viscusi

Vanderbilt Law School Faculty Publications

The frequency and severity of products liability lawsuits have become a matter of increasing importance and concern to the public at large and to American business in particular. The number of product liability cases filed each year escalated dramatically in the 1970s both in absolute terms and as a fraction of all civil cases.' The economic incentives for safety created by these product liability claims no longer are a minor concern but are now a fundamental influence on the economic environment of the firm. In recent years many larger firms have established corporate product safety offices to integrate these product …

Are Individuals Bayesian Decision Makers?, W. Kip Viscusi

Vanderbilt Law School Faculty Publications

There has been increasing interest in whether normative models of individual choice under uncertainty accord with actual behavior. These concerns have been much greater than in other economic contexts because of the particularly severe demands such decisions place on the rationality of the decision maker. The limitations of these decisions have widespread consequences, as they provide the rationale for many governmental efforts to regulate the risks people face. Here I explore the issues raised by a Bayesian decision framework, focusing particularly on my analyses of worker and consumer behavior.
