The True Cost Of Auto Insurance In The Mountain West, 2022, Annie Vong, Saha Salahi, Caitlin J. Saladino, William E. Brown Jr.

Transportation & Infrastructure

This fact sheet examines data on average annual premiums, percent of income spent on auto insurance, and life events associated with the rising cost of auto insurance in the Mountain West (Arizona, Colorado, Nevada, New Mexico, and Utah). The original report includes data on national averages for auto insurance premiums for all fifty states.

Third Party Moral Hazard And The Problem Of Insurance Externalities, Gideon Parchomovsky, Peter Siegelman

All Faculty Scholarship

Insurance can lead to loss or claim-creation not just by insureds themselves, but also by uninsured third parties. These externalities—which we term “third party moral hazard”—arise because insurance creates opportunities both to extract rents and to recover for otherwise unrecoverable losses. Using examples from health, automobile, kidnap, and liability insurance, we demonstrate that the phenomenon is widespread and important, and that the downsides of insurance are greater than previously believed. We explain the economic, social and psychological reasons for this phenomenon, and propose policy responses. Contract-based methods that are traditionally used to control first-party moral hazard can be welfare-reducing in …

Uncertainty > Risk: Lessons For Legal Thought From The Insurance Runoff Market, Tom Baker

All Faculty Scholarship

Insurance ideas inform legal thought: from tort law, to health law and financial services regulation, to theories of distributive justice. Within that thought, insurance is conceived as an ideal type in which insurers distribute determinable risks through contracts that fix the parties’ obligations in advance. This ideal type has normative appeal, among other reasons because it explains how tort law might achieve in practice the objectives of tort theory. This ideal type also supports a restrictive vision of liability-based regulation that opposes expansions and supports cutbacks, on the grounds that uncertainty poses an existential threat to insurance markets.

The Paradox Of Insurance, Gideon Parchomovsky, Peter Siegelman

All Faculty Scholarship

In this Article, we uncover a paradoxical phenomenon that has hitherto largely escaped the attention of legal scholars and economists, yet it has far-reaching implications for insurance law: loss-creation by uninsured parties caused by the presence of insurance. Contrary to the conventional wisdom, we show that insurance can create significant negative externalities by inducing third parties to engage in antisocial, illegal and unethical activities in order to extract money from insureds or insurers. Moreover, as the amount and scope of insurance grows, so does its distortionary effect on third parties. We term this phenomenon the paradox of insurance. The risk …

Private Equity Value Creation In Finance: Evidence From Life Insurance, Divya Kirti, Natasha Sarin

All Faculty Scholarship

This paper studies how private equity buyouts create value in the insurance industry, where decentralized regulation creates opportunities for aggressive tax and capital management. Using novel data on 57 large private equity deals in the insurance industry, we show that buyouts create value by decreasing insurers' tax liabilities; and by reaching-for-yield: PE firms tilt their subsidiaries' bond portfolios toward junk bonds while avoiding corresponding capital charges. Previous work on affiliated or "shadow" reinsurance and capital management misses the important role that private equity buyouts play as recent drivers of these phenomenon. The trend we document is of growing importance in …

The Effect Of The 1918 Influenza Pandemic On U.S. Life Insurance Holdings, Dr. Joanna Short

Economics: Faculty Scholarship & Creative Works

This paper examines the effect of a sharp rise in mortality, the 1918 influenza epidemic, on life insurance holdings in the U.S. The BLS Cost of Living Surveys of 1918-1919 provide a unique opportunity to examine the effect of the pandemic—some households were surveyed before, and others during or shortly after the worst of the influenza outbreak. In addition, I use state-level insurance sales data to compare the increase in spending on insurance in states particularly hard hit by the epidemic, relative to those that were not. I find some evidence that, in the immediate aftermath of the epidemic, those …

Optimal Social Insurance With Informal Child Care, Christine Ho

Research Collection School Of Economics

The possibility of engaging in household child care may exacerbate the incentives of parents and grandparents to falsely claim disability benefits as households also get to save on formal child care costs. This paper considers a multi-generational family model with persistence in privately observed shocks and presents an efficient implementation case for subsidizing formal child care costs of the disabled. An implementation of the optimal scheme that consists of capped formal day care subsidies, non-linear income taxation and asset-testing is proposed. Simulations based on a parametrization that targets key features of the US labor and child care markets suggest that …

Actuarial Modeling And Analysis Of The Hong Kong Life Annuity Scheme, Koon Shing Kwong, Wai-Sum Chan, Johnny Siu-Hang Li

Research Collection School Of Economics

The Hong Kong Mortgage Corporation (HKMC) Limited, which was established in March 1997 and is wholly owned by the government of the Hong Kong Special Administrative Region, has a major mission to develop and provide different financial retirement instruments to Hong Kong residents to help address the income poverty of retirees. In June 2017, HKMC Annuity Limited, a wholly-owned subsidiary of the HKMC was incorporated to implement a new life annuity scheme which would be launched by mid-2018 to cater for the needs of cash-rich Hong Kong old age residents. The objective of the scheme is to provide an additional …

How Liability Insurers Protect Patients And Improve Safety, Tom Baker, Charles Silver

All Faculty Scholarship

Forty years after the publication of the first systematic study of adverse medical events, there is greater access to information about adverse medical events and increasingly widespread acceptance of the view that patient safety requires more than vigilance by well-intentioned medical professionals. In this essay, we describe some of the ways that medical liability insurance organizations contributed to this transformation, and we catalog the roles that those organizations play in promoting patient safety today. Whether liability insurance in fact discourages providers from improving safety or encourages them to protect patients from avoidable harms is an empirical question that a survey …

Examining Moral Hazard In The Healthcare Insurance Market, Samuel Ashby

Honors College Theses

This study aims to examine the effect of insurance coverage on medical expenditure in the United States. The data was gathered from the Household Component Medical Expenditure Panel Survey and is a cross-sectional data set with a sample size of approximately 1500 observations. The study also distinguishes between public and private insurance coverage to compare the potential moral hazard in the two separate markets. The results of this study suggest that insurance status, specifically public, has a strong positive effect on healthcare expenditure. This result, combined with a negative relationship between household income and healthcare expenditure, suggests that the source …

On Central Branch/Reinsurance Risk Networks: Exact Results And Heuristics, Florin Avram, Sooie-Hoe Loke

Mathematics Faculty Scholarship

Modeling the interactions between a reinsurer and several insurers, or between a central management branch (CB) and several subsidiary business branches, or between a coalition and its members, are fascinating problems, which suggest many interesting questions. Beyond two dimensions, one cannot expect exact answers. Occasionally, reductions to one dimension or heuristic simplifications yield explicit approximations, which may be useful for getting qualitative insights. In this paper, we study two such problems: the ruin problem for a two-dimensional CB network under a new mathematical model, and the problem of valuation of two-dimensional CB networks by optimal dividends. A common thread between …

Partitioning Sorted Sets: Overcoming Choice Overload While Maintaining Decision Quality, Benedict C.G. Dellaert, Tom Baker, Eric J. Johnson

All Faculty Scholarship

We investigate the joint use of partitioning and sorting as a choice architecture to overcome consumer choice overload in large product sets. Partitioning first presents a small initial set of alternatives with the option to click through to see the remaining alternatives. Sorting presents alternatives in order of attractiveness based on a user model that is helpful to the decision-maker. We propose that Sets with Partitioning and Sorting (SPSs) improve consumers’ choice outcomes by increasing their focus on the most attractive alternatives and their use of more compensatory decisions. Results from two controlled survey-based experiments and a field study in …

Social Health Insurance Coverage And Financial Protection Among Rural-To-Urban Internal Migrants In China: Evidence From A Nationally Representative Cross-Sectional Study, Wen Chen, Qi Zhang, Andre M. N. Renzaho, Fangjing Zhou, Hui Zhang, Li Ling

Community & Environmental Health Faculty Publications

INTRODUCTION: Migrants are a vulnerable population and could experience various challenges and barriers to accessing health insurance. Health insurance coverage protects migrants from financial loss related to illness and death. We assessed social health insurance (SHI) coverage and its financial protection effect among rural-to-urban internal migrants (IMs) in China.

METHODS: Data from the '2014 National Internal Migrant Dynamic Monitoring Survey' were used. We categorised 170 904 rural-to-urban IMs according to their SHI status, namely uninsured by SHI, insured by the rural SHI scheme (new rural cooperative medical scheme (NCMS)) or the urban SHI schemes (urban employee-based basic medical insurance (UEBMI)/urban …

Mutually Assured Protection Among Large U.S. Law Firms, Tom Baker, Rick Swedloff

All Faculty Scholarship

Top law firms are notoriously competitive, fighting for prime clients and matters. But some of the most elite firms are also deeply cooperative, willingly sharing key details about their finances and strategy with their rivals. More surprisingly, they pay handsomely to do so. Nearly half of the AmLaw 100 and 200 belong to mutual insurance organizations that require member firms to provide capital; partner time; and important information about their governance, balance sheets, risk management, strategic plans, and malpractice liability. To answer why these firms do so when there are commercial insurers willing to provide coverage with fewer burdens, we …

Medicare Secondary Payer And Settlement Delay, Eric Helland, Jonathan Klick

All Faculty Scholarship

The Medicare Secondary Payer Act of 1980 and its subsequent amendments require that insurers and self-insured companies report settlements, awards, and judgments that involve a Medicare beneficiary to the Centers for Medicare and Medicaid Services. The parties then may be required to compensate CMS for its conditional payments. In a simple settlement model, this makes settlement less likely. Also, the reporting delays and uncertainty regarding the size of these conditional payments are likely to further frustrate the settlement process. We provide results, using data from a large insurer, showing that, on average, implementation of the MSP reporting amendments led to …

Behavioral Economics And Insurance Law: The Importance Of Equilibrium Analysis, Tom Baker, Peter Siegelman

All Faculty Scholarship

Because choosing insurance requires consumers to assess risks and probabilities, the demand for insurance has proven to be fertile ground for identifying deviations from rational behavior. Consumers often shun the insurance against large losses that they rationally should want (e.g., floods); and they are attracted to insurance against small losses (extended warranties, low deductibles) that no rational individual should purchase. But the welfare consequences of behavioral anomalies in insurance are complex, because consumers’ irrational behavior takes place in a market profoundly shaped by informational asymmetries. Under some conditions, deviations from rational behavior may actually generate insurance market equilibria that produce …

Can Consumers Make Affordable Care Affordable? The Value Of Choice Architecture, Eric J. Johnson, Ran Hassin, Tom Baker, Allison T. Bajger, Galen Treuer

All Faculty Scholarship

Starting this October, tens of millions will be choosing health coverage on a state or federal health insurance exchange as part of the Patient Protection and Affordable Care Act. We examine how well people make these choices, how well they think they do, and what can be done to improve these choices. We conducted 6 experiments asking people to choose the most cost-effective policy using websites modeled on current exchanges. Our results suggest there is significant room for improvement. Without interventions, respondents perform at near chance levels and show a significant bias, overweighting out-of-pocket expenses and deductibles. Financial incentives do …

The Law And Economics Of Liability Insurance: A Theoretical And Empirical Review, Tom Baker, Peter Siegelman

All Faculty Scholarship

We survey the theoretical and empirical literature on the law and economics of liability insurance. The canonical Shavell model predicts that, despite the presence of some ex ante moral hazard (care-reduction by insureds), liability insurance will generally raise welfare because its risk-spreading gains will likely be larger than its adverse effects on precautionary activities. We discuss the numerous features of liability insurance contracts that are designed to reduce ex ante moral hazard, and examine the evidence of their effects. Most studies conclude that these features work reasonably well, so that liability insurance probably does not generate substantial ex ante moral …

Transparency Through Insurance: Mandates Dominate Discretion, Tom Baker

All Faculty Scholarship

This chapter describes how liability insurance has contributed to the transparency of the civil justice system. The chapter makes three main points. First, much of what we know about the empirics of the civil justice system comes from access to liability insurance data and personnel. Second, as long as access to liability insurance data and personnel depends on the discretion of liability insurance organizations, this knowledge will be incomplete and, most likely, biased in favor of the public policy agenda of the organizations providing discretionary access to the data. Third, although mandatory disclosure of liability insurance data would improve transparency, …

The Shifting Terrain Of Risk And Uncertainty On The Liability Insurance Field, Tom Baker

All Faculty Scholarship

Recent sociological and historical work suggests that insurance risks often are not reliably calculable, except in hindsight. Insurance is “an uncertain business,” characterized by competition for premiums that pushes insurers into the unknown. This essay takes some preliminary steps that extend this insight into the liability insurance field. The essay first provides a simple quantitative comparison of U.S. property and liability insurance premiums over the last sixty years, setting the stage to make three points: (1) liability insurance premiums have grown at a similar rate as property insurance premiums and GDP over this period, providing yet another piece of evidence …

Health Insurance, Risk, And Responsibility After The Patient Protection And Affordable Care Act, Tom Baker

All Faculty Scholarship

This essay explores the new social contract of healthcare solidarity through private ownership, markets, choice, and individual responsibility embodied in the Patient Protection and Affordable Care Act. This essay first explains the four main health care risk distribution institutions affected by the Act – Medicare, Medicaid, the individual and small employer market, and the large group market – with an emphasis on how the Act changes those institutions and how they are financed. The essay then describes the “fair share” approach to health care financing embodied in the Act. This approach largely rejects the actuarial fairness vision of what constitutes …

Tontines For The Invincibles: Enticing Low Risks Into The Health-Insurance Pool With An Idea From Insurance History And Behavioral Economics, Tom Baker, Peter Siegelman

All Faculty Scholarship

Over one third of the uninsured adults in the U.S. below retirement age are between 19 and 29 years old. Young adults, especially men, often go without insurance, even when buying it is mandatory and sometimes even when it is a low cost employment benefit. This paper proposes a new form of health insurance targeted at this group—the “Young Invincibles”—those who (wrongly) believe that they don’t need health insurance because they won’t get sick. Our proposal offers a cash bonus to those who turn out to be right in their belief that they did not really need health insurance. The …

Deposit Insurance Coverage, Ownership, And Banks' Risk-Taking In Emerging Markets, Apanard P. Angkinand, Clas Wihlborg

Business Faculty Articles and Research

We ask how deposit insurance systems and ownership of banks affect the degree of market discipline on banks' risk-taking. Market discipline is determined by the extent of explicit deposit insurance, as well as by the credibility of non-insurance of groups of depositors and other creditors. Furthermore, market discipline depends on the ownership structure of banks and the responsiveness of bank managers to market incentives. An expected U-shaped relationship between explicit deposit insurance coverage and banks' risk-taking is influenced by country specific institutional factors, including bank ownership. We analyze specifically how government ownership, foreign ownership and shareholder rights affect the disciplinary …

The Relation Between Regulation And Class Actions: Evidence From The Insurance Industry, Eric Helland, Jonathan Klick

All Faculty Scholarship

Standard law and economics models imply that regulation and litigation serve as substitutes. We test this by looking at the incidence of insurance class actions as a function of measures of regulatory enforcement. We also look specifically at whether states with clear regulatory standards regarding the use of OEM parts experience less litigation over this issue. We find no evidence of substitution between regulation and litigation. We also examine the possibility that litigation is more frequent in states where regulators are more likely to be captured by industry interests, finding no support for this hypothesis either. Instead, litigation is more …

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

All Faculty Scholarship

Whereas the literature evaluating the effect of tort reforms has focused on reported incurred losses, this paper examines the long run effects using a comprehensive sample by state of individual firms writing medical malpractice insurance from 1984-2003. The long run effects of reforms are greater than insurers' expected effects, as five year developed losses and ten year developed losses are below the initially reported incurred losses for those years following reform measures. The quantile regressions show the greatest effects of joint and several liability limits, noneconomic damages caps, and punitive damages reforms for the firms that are at the high …

Is Exchange Risk Priced Beyond Intertemporal Risk?, Ines Chaieb, Stefano Mazzoto, Oumar Sy

Faculty and Research Publications

Recent conditional tests show that exchange risk is priced in integrated international markets. However, these results are typically obtained assuming that intertemporal risk does not matter. We test an intertemporal international asset-pricing model where the investment opportunity set is dynamic. Using a conditional orthogonalization approach, we investigate whether the exchange risk is priced once the market and intertemporal risks are fully taken into account. We find that, in addition to the market and intertemporal risks, the exchange risk is an important determinant of risk premium. We also find that the intertemporal risk, which is often overlooked in the literature, is …

The Effects Of Malpractice Tort Reform On Defensive Medicine, Heather M. O'Neill, Katherine D. Hennesy

Business and Economics Faculty Publications

Medical malpractice crises occur across states to differing degrees, thus the proposed changes in state tort reforms differ accordingly. The primary overt goals of tort reform aim to address: rising medical malpractice insurance rates, increased frequency and severity of awards, and the increased incidence of doctors shuttering offices or fleeing states due to untoward malpractice environments. A secondary goal of tort reform is to reduce health care costs attributed to malpractice costs. Clearly, as malpractice tort reforms are debated in state capitols and reforms take place, the effects of the reforms on the goals above can be examined. However, there …
