Capital-based regulation,portfolio risk and capital determination: Empirical evidence from the US property–liability insurers

This paper examines the impact of capital-based regulation on the insurer’s risk and capital adjustments in the US property–liability insurance industry. We conduct the three-stage least squares (3SLS) procedure to estimate a simultaneous equations model. The key finding is that undercapitalized insurers increase capital to avoid regulatory costs and take more risks to generate higher returns. We also investigate firm characteristics that determine the insurer’s capital structure. The results indicate that insurers appear to rely heavily on retained earnings to make up their capital shortage and insurers with greater growth opportunity may hold high levels of capital to control for agency problems. Robustness tests with an alternative risk measure and subsamples present consistent results.     

MARKET POWER IN THE PROPERTY/CASUALTY INSURANCE INDUSTRY

Abstract: Pro-consumer groups have charged that insurance firms are able to exercise market power to reduce coverage and/or increase rates. The ability of firms to earn economic rents (abnormal profits) is a factor in banks' interest in entering insurance markets. In classical economics such collusion is usually only possible with cartels. Recent work, examining the relationship between industry structure indicates that the power that can be exercised by cartels may be more limited than under the classical paradigms. We examine the ability of insurers to exercise market power in light of these modern theories.     

The Impact of Insurance Fraud Detection Systems

This article analyzes the impact of detection systems in an insurance fraud context. In a noncommitment Costly State Verification setting insurers can only detect fraudulent claims by performing costly audits, and policyholders are overcompensated by the optimal insurance contract. We show that auditing becomes more effective and overcompensation can be reduced, when insurers are able to condition their audits on the information provided by detection systems.     

State regulation and the structure,conduct, efficiency and performance of US auto insurers

This research investigates the impact of regulation on state automobile insurance markets while controlling for other state insurance market characteristics that may be related to performance. Data for a large sample of insurers are analyzed. The results suggest that insurers in competitive and non-stringently regulated states may benefit from market power by charging higher unit prices, however insurers in these states are on average more cost X-efficient and cost X-efficient insurers charge lower prices and earn smaller profits. The empirical results also suggest that insurers in some rate regulated states are less revenue and cost-scale efficient than in competitive states.     

“Crises” in medical malpractice insurance: Evidence of excessive price-cutting in the preceding soft market

Prior work suggests that heterogeneous information or weak incentives for solvency could have caused some general liability insurers to charge low ex ante prices during the early 1980s and mid-to-late 1990s, putting downward pressure on other firms’ prices and plausibly aggravating subsequent periods of rapid premium growth. We analyse whether the 1994–1999 “soft” market in medical malpractice insurance led some firms to underprice, grow rapidly, and subsequently experience upward revisions in loss forecasts (“loss development”), which could have aggravated subsequent market “crises”. Consistent with the underpricing hypothesis, the results indicate a positive relation between loss development and premium growth among growing firms. Underpricing was likely more prevalent among non-specialist malpractice insurers.     

An empirical analysis of the economic impact of federal terrorism reinsurance

This paper examines the role of the federal government in the market for terrorism reinsurance. We investigate the stock price response of affected industries to a sequence of 13 events culminating in the enactment of the Terrorism Risk Insurance Act (TRIA) of 2002. In the industries most likely to be affected by TRIA—banking, construction, insurance, real estate investment trusts, transportation, and public utilities-the stock price effect was primarily negative. The Act was at best value-neutral for property-casualty insurers because it eliminated the option not to offer terrorism insurance. The negative response of the other industries may be attributable to the Act's impeding more efficient private market solutions, failing to address nuclear, chemical, and biological hazards, and reducing market expectations of federal assistance following future terrorist attacks.     

Deterring Fraud: The Role of General Damage Awards in Automobile Insurance Settlements

Awards for pain and suffering and other noneconomic losses account for over half of all damages awarded under third‐party auto insurance bodily injury settlements. This article hypothesizes that third‐party insurers use general damage awards to reduce the incentive to submit exaggerated claims for specific damages for injuries and lost wages. Consistent with this hypothesis, the article finds evidence using data on over 17,000 closed bodily injury claims that special damage claims that exceed their expected value receive proportionally lower general damage awards than claims that do not. Among the implications of this research is the possibility that insurers will be less zealous in challenging fraudulent special damage claims under a third‐party insurance regime than they will be under a first‐party insurance regime in which access to general damages is limited.     

Mortality-Indexed Annuities Managing Longevity Risk Via Product Design

Abstract

Longevity risk has become a major challenge for governments, individuals, and annuity providers in most countries. In its aggregate form, the systematic risk of changes to general mortality patterns, it has the potential for causing large cumulative losses for insurers. Since obvious risk management tools, such as (re)insurance or hedging, are less suited for managing an annuity provider’s exposure to this risk, we propose a type of life annuity with benefits contingent on actual mortality experience.

Similar adaptations to conventional product design exist with investment-linked annuities, and a role model for long-term contracts contingent on actual cost experience can be found in German private health insurance. By effectively sharing systematic longevity risk with policyholders, insurers may avoid cumulative losses.

Policyholders also gain in comparison with a comparable conventional annuity product: Using a Monte Carlo simulation, we identify a significant upside potential for policyholders while downside risk is limited.     

"Any Willing Provider" laws not preempted by Employee Retirement Income Security Act (ERISA). Kentucky Association of Health Plans, Inc. et. al. v. Miller, Commissioner, Kentucky Department of Insurance

"Any Willing Provider" laws are not preempted by ERISA because they are state laws regulating insurance if they are (1) specifically directed toward entities engaged in insurance and (2) substantially affect the risk-pooling arrangement between the insurer and the insured. Thus, a state may prohibit health maintenance organizations (HMOs) from creating exclusive "provider networks" of doctors, hospitals and other health care providers by excluding other providers who are "willing and able" to comply with all the HMO's contractual terms if the law meets the new two-prong test established by the Supreme Court in this case. The Court made a "clean break" from using the McCarran-Ferguson Act factors for determining whether certain practices constitute "the business of insurance," when deciding when they regulate insurance for purposes of ERISA preemption.     

RELATIVE EFFICIENCIES OF NON-LIFE REINSURANCE MARKETING METHODS

Abstract: This paper extends the study of the relative cost efficiency of insurance delivery systems from the primary market to the market for non-life reinsurance services. As in the primary market for insurance services there are two predominant methods of marketing reinsurance services: reinsurers who rely on employees, termed direct writers, and those who rely on brokers.
An extensive literature relating to the primary market for non-life insurance consistently indicates that independent agency insurers have a cost disadvantage relative to exclusive agency insurers. This literature also suggests that independent agency insurers may supply superior service but a continuing erosion of the market share of independent agency insurers suggests that the perceived service differential is not valued sufficiently to offset the perceived cost differential.
The authors find evidence that, cet. par., broker supplied reinsurers operate with lower costs than direct reinsurers but we find less convincing evidence of a service differential favoring direct reinsurers. More significantly, we observe that the largest component of the traditional measure of the reinsurer's cost is the commission paid back to the primary insurer: the seemingly lower cost brokers provide a higher net cost product. Yet brokers thrive in the marketplace suggesting the existence of a product differentiated by service or quality. With the important caveat that measures of service are imperfect and data is limited, we find no evidence of a service differential.     

Aufsichtsrechtliche Rahmenbedingungen für die Tätigkeit von EU-Versicherern in der Türkei

In recent years the Turkish insurance market has exerted a strong appeal, especially for insurers seated in the EU, in view of its exponential growth rates and its dormant growth potential. EU insurers are, however, subject to more stringent insurance supervisory requirements when entering this insurance market, external to the EU, than when expending into other European insurance markets.     

Why haven’t U.S. GAAP and IFRS on insurance contracts converged? Evidence from an unsuccessful joint project

This study examines the FASB’s and IASB’s unsuccessful joint project on accounting for insurance contracts. It highlights the divergent views the Boards may hold on certain fundamental accounting issues. Further, this study examines how the costs and benefits of accounting standard convergence can vary within an industry, conditional on factors such as prior accounting standards and firms’ global operations. Empirically, U.S. insurers’ negative market reactions to the joint insurance project suggest U.S. investors perceived net costs would outweigh net benefits. This study also finds that market reactions of U.S. insurers were more negative than those of European insurers. The results of cross-sectional analyses indicate that U.S. life insurers perceived higher net costs associated with the joint project, while European insurers with more global revenue perceived higher net benefits. This work illuminates some of the challenges facing standard setters when attempting to develop a globally acceptable set of financial reporting standards.     

Are non-risk based capital requirements for insurance companies binding?

We investigate whether insurers base their solvency margins on risk factors even when operating under a supervisory regime where minimum solvency requirements do not fully take such risk factors into account. To do this, we use a dataset of about 350 Dutch insurers from all major lines of business during the pre-Solvency II period 1995–2005. We find that the levels of insurers’ actual solvency margins are related to their risk characteristics and not to regulatory solvency requirements. Consequently, the vast majority of insurers hold much more capital than required, i.e. non-risk based capital requirements generally are not binding. Requirements are found to affect solvency adjustment behaviour, though. More specifically, below-target capital ratios are raised most rapidly by those insurers whose targets are relatively close to the regulatory minimum. One implication from our results is that, because insurers already follow a risk-based approach, the transition to the new European regulatory framework, Solvency II, is likely to be smooth.     

Economies of scope in financial services: A DEA efficiency analysis of the US insurance industry

This paper investigates economies of scope in the US insurance industry over the period 1993–2006. We test the conglomeration hypothesis, which holds that firms can optimize by diversifying across businesses, versus the strategic focus hypothesis, which holds that firms optimize by focusing on core businesses. We analyze whether it is advantageous for insurers to offer both life-health and property-liability insurance or to specialize in one major industry segment. We estimate cost, revenue, and profit efficiency utilizing data envelopment analysis (DEA) and test for scope economies by regressing efficiency scores on control variables and an indicator for strategic focus. Property-liability insurers realize cost scope economies, but they are more than offset by revenue scope diseconomies. Life-health insurers realize both cost and revenue scope diseconomies. Hence, strategic focus is superior to conglomeration in the insurance industry.     

Market structure and the efficiency of European insurance companies: A stochastic frontier analysis

This paper is motivated by the progressive liberalisation of the European insurance market in recent years. It uses stochastic frontier analysis to estimate Flexible Fourier cost functions for European insurance companies. Separate frontiers are estimated for life, non-life and composite companies. We adopt a maximum likelihood approach to estimation in which the variance of both one-sided and two-sided error terms is modelled jointly with the frontiers. This approach allows us to simultaneously control for the impact of heteroskedasticity on the estimation of scale economies as well as estimating the effect of firm size and market structure on X-inefficiency. The study draws on Standard & Poor’s Eurothesys data set of financial reports for the period 1995 to 2001. This provides technical and non-technical accounts at year-end for life, non-life and composite insurance businesses in 14 major European countries. Our estimates suggest that over this period most European insurers were operating under conditions of decreasing costs (increasing returns to scale), and that company size and domestic market share were significant factors determining X-inefficiency. Larger firms, and those with high market shares, tend to have higher levels of cost inefficiency.     

Do Publicly Traded Property–Casualty Insurers Cater to the Stock Market?

This article examines the catering theory in the insurance industry. We investigate whether managers of publicly traded insurers pursue a growth strategy catering to the stock market's preference. Two hypotheses are tested in this study: (1) an insurer will devote more efforts to increasing premium growth when the stock market places greater values on growth, and (2) this catering effect will be more pronounced at firms where managers have greater incentives to maximize short‐term stock prices. We find evidence supporting both hypotheses. Our study discovers a new channel through which the stock market and executive compensation affect insurance companies’ business strategies and the insurance market. The implication of the interplay between insurers and the stock market is significant and deserves future research.     

Employer strategies to combat health care plan fraud

Each year health care fraud drains millions of dollars from employer-sponsored health plans. Historically, employers have taken a rather tolerant view of fraud. As the pressure to manage health plan costs increases, however, many employers are beginning to see the detection and prosecution of fraud as an appropriate part of a cost management program. Fraud in medical insurance covers a wide range of activities in terms of cost and sophistication--from misrepresenting information on a claim, to billing for services never rendered, to falsifying the existence of an entire medical organization. To complicate matters, fraudulent activities can emanate from many, many sources. Perpetrators can include employees, dependents or associates of employees, providers and employees of providers--virtually anyone able to make a claim against a plan. This article addresses actions that employers can take to reduce losses from fraud. The first section suggests policy statements and administrative procedures and guidelines that can be used to discourage employee fraud. Section two addresses the most prevalent form of fraud--provider fraud. To combat provider fraud, employers should set corporate guidelines and should enlist the assistance of employees in identifying fraudulent provider activities. Section three suggests ways to improve fraud detection through the claims payment system--often the first line of defense against fraud. Finally, section four discusses the possibility of civil and criminal remedies and reviews the legal theories under which an increasing number of fraud cases have been prosecuted.     

Insurance Markets With Differential Information

This article attempts to understand the outcomes when each party of an insurance contract simultaneously has superior information. I assume that policyholders have superior information about specific risks while insurers have superior information about general risks. I find that low-general-risk policyholders purchase insurance, while high-general-risk policyholders are self-insured. Among the low-general-risk policyholders, high-specific-risk policyholders purchase full insurance, while low-specific-risk policyholders purchase partial insurance. When insurers can strategically publicize their information, efficiency is improved because high-general-risk policyholders purchase actuarially fair insurance. The market segmentation is also found based on the general-risk type and the publicizing of information.     

A Reexamination of the Corporate Demand for Reinsurance

This study examines the effect of the state of the international reinsurance market on the demand for reinsurance by U.S. insurers using data from the years 1993 through 2000. Both the overall demand for reinsurance and the utilization of foreign reinsurance by U.S. insurers are explored. In addition to supporting the findings of prior literature related to the traditional motives for the corporate demand for insurance, evidence indicates that the state of the U.S. reinsurance industry impacts the amount of reinsurance demanded by U.S. insurers. The study also investigates reasons why U.S. insurers utilize a reinsurance program composed of both U.S. and foreign reinsurers. The results indicate that the decision to utilize some percentage of foreign reinsurance is driven primarily by the financial and operational characteristics of the ceding company such as firm size, group affiliation, and organizational form. However, no support is found for the hypothesis that possible differences between the foreign and U.S. reinsurance markets impact the decision to utilize foreign reinsurance.     

Recent Developments in the Aviation Insurance Industry

The aviation industry has been hard hit in recent years. While there are numerous factors that have contributed to the industry's dilemma, rising and volatile insurance premiums—particularly after the events of 9/11—have posed a particular problem for many airline managers. Despite a general trend for accident rates involving commercial passenger airplanes to decrease as aviation technology has advanced over the years and airplanes have become safer, the aviation insurance market has been far from stable. This article provides an overview of how the aviation insurance industry works and how it has changed in recent years. We take a look at how the risk is spread between insurers, how insurers treat deliberate acts of violence, and lastly, how insurers price the risk. Our article shows that the aviation insurance market has undergone considerable changes in recent years and that it has adjusted to the post-9/11 aviation insurance realities being reasonably ready to handle events of an even more catastrophic magnitude.
