The U.S. Property and Liability Insurance Industry: Firm Growth,Size, and Age

The relationship between firm size, age, and growth is tested for the U.S. property and liability (P‐L) insurance industry, and the determinants of firm characteristics on firm growth are analyzed. Using Heckman's two‐stage methodology, this article examines the relationship between corporate growth and firm size. The relationship between firm growth and firm age is also investigated. Furthermore, to determine time‐varying effects, the analysis is conducted for the different subperiods. The results of this article strongly support Gibrat's Law in the U.S. P‐L insurance market for the testing periods. The results are consistent for longer time periods and for shorter subperiods. It also finds that young firms grow faster than old firms during the sample periods. Related to the determinants of firm characteristics on firm growth, insurers using less input cost tend to grow fast. Economies of scope are positively related to firm growth as well.     

Insurer Growth Strategies

We study corporate growth strategy within the U.S. property–casualty insurance industry—where firms are required to report uniquely detailed operating information. We present and test two hypotheses related to the manner in which firms choose to grow: the pecking order hypothesis and the managerial discretion hypothesis. Our results imply that insurers follow a general pecking order of growth strategies, where they tend to grow first by entering new states, then by adding new lines of business, and finally through acquisitions. This order is consistent with firms initially choosing to grow in the least costly and complex manner and subsequently choosing more costly and complex methods. We also find evidence in support of the managerial discretion hypothesis as mutual insurers are less likely to choose to grow and, when they do, they tend to select less complex growth methods.     

Reinsurance and corporate taxation in the United Kingdom life insurance industry

There are two main tax-related arguments regarding the use of reinsurance – the income volatility reduction and the income level enhancement arguments. The income volatility reduction argument contends that firms facing convex tax schedules have incentives to hedge in order to reduce the volatility of their annual taxable income and thereby lower expected tax liabilities [Smith, C.W., Stulz, R.M., 1985. Optimal hedging policies. Journal of Financial and Quantitative Analysis 19, 127–140]. The income level enhancement argument, advanced by Adiel [Adiel, R., 1996. Reinsurance and the management of regulatory ratios and taxes in the property–casualty insurance industry. Journal of Accounting and Economics 22, 207–240], is more specific to hedging via reinsurance. This perspective holds that reinsurance enhances current reported earnings via the receipt of reinsurance commissions and so increases tax liabilities. Consequently, insurance firms with high marginal tax rates should use less reinsurance than those with low marginal tax rates if tax matters. Prior studies using data on financial derivatives have produced mixed results on the validity of the first argument, while Adiel (1996) finds the second argument insignificant in his study of the use of reinsurance by a sample of United States (US) property–liability insurance firms. This study tests the two tax-related arguments using 1992–2001 data for a sample of United Kingdom (UK) life insurance firms. We find that UK life insurers with low before-planning marginal tax rates tend to use more reinsurance; in contrast, tax convexity is found to have no significant impact on the purchase of reinsurance and so the volatility-reduction argument is not supported.     

Effizienz und Eigentümerstruktur: Eine empirische Analyse des deutschen Lebensversicherungsmarktes

We provide new insights into the effect of ownership on efficiency by analyzing the German life insurance market over the period 2002–2005. Previous research on alternative organizational forms in the life insurance industry has focused on stock and mutual ownership only. Due to the uniqueness of the German insurance market, where privately-owned companies face competition by public insurers, we add to the recent literature the well known debate on public versus private ownership, by investigating stock, mutual and public ownership forms. Using traditional DEA, we calculate technical efficiency and cost efficiency scores to test the efficient structure hypothesis as well as the expense preference hypothesis. Our results give strong support to the latter, while we find no evidence that public ownership is an efficient corporate structure for life insurers. The group of stock firms dominates both, mutual and public insurers, although differences between stock and mutual companies are smaller than differences between stock and public firms. Analyzing within-group results, our findings suggest that high efficiency scores can be associated with certain firm characteristics which are publicly available: high returns on assets, low cancellation rates and low costs.     

Auditor quality,audit fees,organizational structure,and risk taking in the US life insurance industry

Using a system of simultaneous equations, this study examines the relation among external audit monitoring, in the US life insurance industry. We find insurers with higher leverage risk and surplus risk are more likely to use Big‐4 auditors and to pay higher fees. In return, insurers hiring Big‐4 auditors and paying higher audit fees have lower leverage risk and surplus risk. Second, the results suggest that mutual life insurers have a higher leverage risk and surplus risk than stock life insurers. This evidence is in contrast to that for property–liability insurance companies. Third, we find insurers are less likely to hire Big‐4 auditors and to pay higher audit fees after implementation of the Sarbanes–Oxley Act (SOX). Finally, life insurers with Big‐4 auditors or paying higher audit fees are more likely to take lower risks after the implementation of SOX.     

Impact of interest rates on the life insurance market development: Cross-country evidence

Studies have found that interest rates create incentives for insurance firms to focus on financial markets through investments. Using a cross-country context, we conjecture that interest rates affect the life insurance market’s development. Using an initial sample comprising the time series of interest rates and insurance markets’ measures from 34 countries across 1998–2017, we found that the density and penetration of the life insurance market is low in countries with high interest rates. Using another sample of 6,451 observations from insurance firms operating in the same 34 countries, we verified that the financial and operational incomes are equally significant in predicting the net income for life insurance companies that operate in countries with high interest rates. Our study contributes to observations that the lack of governmental control over public expenses impacts interest rates and, thereby, the opportunities for insurers.     

Interest Rate Risk and Equity Values of Life Insurance Companies: A GARCH–M Model

The importance of managerial decisions related to interest‐sensitive cash flows has received considerable attention in the insurance literature. Consistent with the interest‐sensitive nature of insurer assets and liabilities, empirical research has shown that insurer insolvency is significantly related to interest rate volatility. We investigate the interest rate sensitivity of monthly stock returns of life insurers based on a generalized autoregressive conditionally heteroskedastic in the mean (GARCH–M) model. We examine three different portfolios (equally weighted, risk‐based, and size‐based) with binary variables to explicitly account for varying interest rate strategies adopted by the Federal Reserve System. Results based on data for the period 1975 through 2000 indicate that life insurer equity values are sensitive to long‐term interest rates and that interest sensitivity varies across subperiods and across risk‐based and size‐based portfolios. The results complement insolvency research that links insurer financial performance to changes in interest rates.     

Production Efficiency in the Austrian Insurance Industry: A Bayesian Examination

This paper examines the developments in the production efficiency of the Austrian insurance market for the period 1994‐1999 using firm‐specific data on life/health and non‐life insurers obtained from the Austrian insurance regulatory authority. The article uses a Bayesian stochastic frontier to obtain aggregate and firm‐specific estimates of production efficiency across insurer types and time. The study provides strong evidence that the process of deregulation had positive effects on the production efficiency of Austrian insurers. The life/health and non‐life firms showed similar patterns of development in that they were less efficient during the years 1994‐1996 and significantly more efficient in 1997‐1999. If the Austrian experience is representative, similar benefits from deregulation may be expected for the Central and Eastern European countries that prepare for the accession to the European Union.     

The pricing of audit and non-audit services in a regulated environment: a longitudinal study of the UK life insurance industry

This paper studies the relationship between audit and non-audit service fees paid to the statutory auditor by UK life insurance firms, utilising an extensive panel-data sample set for the period 1999–2009. Consistent with a knowledge spillover (impairment of independence) hypothesis, we predict and find that audit fees are positively (negatively) associated with actuarial (tax service) fees. Additionally, our results indicate that regulatory changes enforced after 2004 deterred UK life insurance firms from purchasing non-audit services that are perceived to impair auditor independence. Finally, we find evidence concerning the inter-temporal determination of audit fees.     

Restructuring of the Dutch Nonlife Insurance Industry: Consolidation,Organizational Form,and Focus

Since the deregulation of the European insurance market in 1994, Dutch nonlife insurance firms have sized up and increased their focus. Concurrently, the stock organizational form has become increasingly dominant. This article investigates these 1995–2005 trends from a cost‐efficiency perspective. We observe substantial economies of scale that are even larger for smaller firms. In line with the efficient structure hypothesis, both stocks and mutuals are found to have comparative cost advantages. Supporting the strategic focus hypothesis, we find that more specialized insurers have lower costs. Thick frontier efficiency estimates point to large cost X‐inefficiencies that have moderately decreased over time.     

“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.     

On the exposure of insurance companies to sovereign risk—Portfolio investments and market forces

A sovereign debt crisis can have significant knock-on effects in the financial markets and put financial stability at risk. This paper focuses on the transmission of sovereign risk to insurance companies as some of the largest institutional investors in the sovereign bond market. We use a firm level panel dataset that covers large insurance companies, banks and non-financial firms from nine countries over the time period from 1 January 2008–1 May 2013. We find significant and robust transmission effects from sovereign risk to domestic insurers. The impact on insurers is not significantly different from that on banks but larger than for non-financial firms. We find that systemically important insurers are more closely linked to the domestic sovereign. Based on European data, we show that risks in sovereign bond portfolios are an important driver of insurer risk, which is not reflected in current insurance regulation (incl. Solvency II in Europe).     

Efficiency in the UK life insurance industry: Mutual firms versus proprietary firms

The paper discusses the main tenets of stakeholder theory and agency theory and goes on to analyse the relative performance of a sample of 100 mutual and proprietary life insurance companies in the UK during the period 1992–1996. The paper concludes that there is weak evidence to support the contention that mutual life insurers are relatively more cost efficient than proprietary insurers. Mutual companies in the sample perform well relative to proprietary companies in terms of annual surpluses and expenses ratios. There is also evidence that fund managers in mutual companies perform at least as well on average as those in proprietary companies.     

Form Over Matter: Differences in the Incentives to Convert Using Full Versus Partial Demutualization in the U.S. Life Insurance Industry

We explore the recent wave of demutualizations in the U.S. life insurance industry and analyze if the motives were similar for mutual life insurers that fully demutualized versus those that converted to mutual holding company (MHC) form. We find that fully demutualizing insurers were primarily motivated by a desire to gain access to external capital markets while those that chose MHC were motivated by other incentives including a tax‐based incentive. We also document that after conversion, fully demutualizing insurers more aggressively increase their exposure to risks they have a comparative advantage to bear than do firms that convert to MHC.     

Adverse Selection in Reinsurance Markets

This paper looks for evidence of adverse selection in the relationship between primary insurers and reinsurers. We test the implications of a model in which informational asymmetry—and therefore, its negative consequences—decline over time. Our tests involve a data panel consisting of U.S. property-liability insurance firms that reported to the National Association of Insurance Commissioners during the period 1993–2012. We find that the amount of reinsurance, insurer profitability, and insurer credit quality all increase with the tenure of the insurer–reinsurer relationship.     

The Determinants of Credit Ratings in the United Kingdom Insurance Industry

This paper examines the determinants of external credit ratings attained by insurance firms in the United Kingdom (UK) and of the likelihood that insurers will have such an assessment. Using panel data relating to A.M. Best‐rated and Standard and Poor's (S&P)‐rated insurers over the period 1993–1997, a trichotomous logit model and an ordered probit model with sample selection are employed to show that the factors which influence the likelihood of having external credit assessments not only vary between the two agencies but also differ from those which determine the ratings themselves. Our results are shown to be of potential interest to participants in the insurance industry and policy‐makers alike.     

Financial factors and firm growth: evidence from financial data on Taiwanese firms

We investigate the possible predictability of firm growth in Taiwan using cross-sectional data of financial factors for the years 1997 and 2003 via principal component analysis. Our results reveal that the 18 financial variables (sales growth rate, total assets, total sales, return on assets, return on equity, gross margin, operating cost minus depreciation divided by sales plus other trading income, acid test ratio, debt–equity ratio, time interest earned, average receivables per average daily sales, inventory, average payables per average daily sales, working capital, working capital as a fraction of total assets, long-term liabilities as a fraction of total assets, and sales as a fraction of net worth of the firm) that we employ bunch together into five different financial ratios for the years 1997 and 2003 that are stable between these years. These financial factors are short-term liquidity, return on investment, long-term liquidity, firm size and capital turnover. Regressing these ratio groups (extracted principal components) on firm growth, we find return on investment in the year 1997 was positively and significantly related to firm growth, while long-term solvency was negatively related to firm growth. In addition, smaller firms tended to grow faster. By 2003, larger firms grew faster than smaller ones and short-term liquidity was positively and significantly related to firm growth, while return on investment was no longer a significant determining factor. Our findings suggest that firms that finance internally or do not rely too heavily on indebtedness may end up growing slower during boom periods but they are the ones that survive and outperform after the bust.     

Accounting and litigation risk: evidence from Directors’ and Officers’ insurance pricing

We study whether and how financial reporting concerns are priced by insurers that sell Directors’ and Officers’ (D&O) insurance to public firms. As D&O insurers typically assume the liabilities arising from shareholder litigation, the premiums they charge for D&O coverage reflect their assessment of a company’s litigation risk. Using a sample of public firms in the 2001–2004 Tillinghast D&O insurance surveys, we document that firms with lower earnings quality or prior accounting restatements pay higher premiums after controlling for other factors impacting litigation risk. In addition, insurers’ concerns about financial reporting are most evident for firms with restatements that are not revenue or expense related, are greater in the period following the passage of the Sarbanes–Oxley Act of 2002, and are greater for firms with financial reporting problems that linger. Our results are consistent with past restatements being viewed as evidence of chronic problems with a firm’s financial statements. By analyzing archival data, we can also quantify the effects of other determinants of D&O premiums (such as business risk, corporate governance, etc.) identified by Baker and Griffith (Univ Chic Law Rev 74(2):487–544, 2007a) through interviews regarding the D&O underwriting process.     

Institutional Ownership Stability and Risk Taking: Evidence From the Life–Health Insurance Industry

We investigate the relationship between risk taking of life–health (LH) insurers and stability of their institutional ownership within a simultaneous equation system model. Three main results are obtained. First, stable institutional ownership of is associated with lower total risk of LH insurers, supporting the prudent‐man law hypothesis. Second, when investors are sorted in terms of stringency of the prudent‐man restrictions, their negative effect on risk holds for all, except insurance companies, as owners of LH insurers. Third, large institutional owners do not raise the riskiness of the investee‐firms, as proposed by the large shareholder hypothesis. Regulatory implications are drawn.     

Effects of Corporate Diversification: Evidence From the Property–Liability Insurance Industry

Using a sample of property–liability insurers over the period 1995–2004, we develop and test a model that explains performance as a function of line‐of‐business diversification and other correlates. Our results indicate that undiversified insurers consistently outperform diversified insurers. In terms of accounting performance, we find a diversification penalty of at least 1 percent of return on assets or 2 percent of return on equity. These findings are robust to corrections for potential endogeneity bias, alternative risk measures, alternative diversification measures, and an alternative estimation technique. Using a market‐based performance measure (Tobin's Q) we find that the market applies a significant discount to diversified insurers. The existence of a diversification penalty (and diversification discount) provides strong support for the strategic focus hypothesis. We also find that insurance groups underperform unaffiliated insurers and that stock insurers outperform mutuals.
