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.     

Ownership Structure and Control: Property-Casualty Insurer Conversion to Stock Charter

We examine 98 property-casualty insurance companies that convert to stock charter from a mutual or reciprocal form of organization. Our evidence shows converting firms have low surplus, significant growth in premium income, and draw down on their non-financial assets in years prior to conversion. Following conversion there is significant growth in assets and the number of States licensed. We also show by examining evidence on the riskiness of firms' operations that converting companies began operating like stock companies prior to conversion. Thus, our evidence suggests there can be important costs associated with the operation of a mutual or reciprocal insurance company. These costs can include the opportunity costs associated with foregone investments arising because of higher incremental capital costs inherent in the mutual or reciprocal forms of ownership. There also is a cost disadvantage if a mutual or reciprocal is operating in activities more appropriate for the stock ownership form. These costs can in particular circumstances offset the advantage mutual ownership affords in controlling incentives to transfer wealth from policyholders to equityholders.     

The Demise of the Mutual Organizational Form: An Investigation of the Life Insurance Industry

We investigate the role of organizational structure in financial services markets by examining the U.S. life insurance industry. Traditionally, stock and mutual life insurers were equally represented, but now the industry is mainly composed of stock firms. We find operational efficiency, access to capital, and tax savings are important determinants for this shift. The incentive to demutualize differs by the type of conversion: full demutualization is chosen for efficiency and access to capital reasons and partial conversion, using a mutual holding company, is chosen for tax savings. Firm operational efficiency improves after conversion. We also find the efficiency of the stock organizational form dominates that of the mutual structure during our sample period, 1995 to 2004.     

The Determinants of Financial Derivatives Use in the United Kingdom Life Insurance Industry

This paper examines the determinants of financial derivatives use in the United Kingdom life insurance industry. We estimate a probit regression model and a Heckman two-stage sample selection regression model using a sample of eighty-eight U.K. life insurers in 1995. Our results indicate that the propensity to use derivative instruments is positively related to a firm's size, leverage and international links, and negatively related to the extent of reinsurance. We also find that mutual life insurance firms have a greater propensity than stock firms to use derivatives. The positive relation with leverage and the negative relation with reinsurance support the hypothesis that U.K. life insurers use derivatives to offset risk, rather than as a speculative means of income generation. Firm size and organizational form are the main influences on the extent of financial derivatives use.     

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.     

Economies of scale in financial institutions: A general model applied to insurance

This study describes and applies an alternative methodology for measuring economies of scale in financial institutions. A complete model of a profit maximizing financial intermediary is constructed which yields a set of first-order conditions. These together with linear specifications of appropriate revenue and cost functions permit a two-stage estimation of cost and revenue parameters.Application of the model is illustrated by using data from the Canadian general insurance industry. Estimated cost functions suggest (1) that joint stock insurance firms realize no economies of scale from expansion of activity in any one line of insurance but realize diversification economies from writing the same aggregate dollar premiums over appreciably more lines; (2) that mutual companies enjoy direct economies of scale from a simultaneous expansion of insurance lines and, possibly, some diversification economies. Diversification economies may or may not yield special advantages to large firms depending on the competitive state of the reinsurance market.     

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.     

Fund ownership and stock price informativeness of Chinese listed firms

We examine the impact of mutual fund ownership on stock price informativeness in China. Existing evidence shows that stock price informativeness is low in China, and attributes this to firms’ lack of disclosure incentives under the weak investor protection institutional environment. Mutual funds are more sophisticated and influential than individual investors to monitor firms, and thus serve as an external governance mechanism to improve corporate transparency. However, the impact of mutual funds in China can also be moderated by state ownership of listed firms, which reduces firms’ dependence on outside investors for capital. Indeed, we find that mutual fund ownership is positively related to share price informativeness, but this effect is less pronounced among state-controlled firms. The main policy implication from our findings is that mutual funds contribute to the corporate information environment of emerging economies but further privatization of listed firms would be needed to realize greater benefit.     

Consolidation and efficiency in the US life insurance industry

This paper examines the relationship between mergers and acquisitions, efficiency, and scale economies in the US life insurance industry. We estimate cost and revenue efficiency over the period 1988–1995 using data envelopment analysis (DEA). The Malmquist methodology is used to measure changes in efficiency over time. We find that acquired firms achieve greater efficiency gains than firms that have not been involved in mergers or acquisitions. Firms operating with non-decreasing returns to scale (NDRS) and financially vulnerable firms are more likely to be acquisition targets. Overall, mergers and acquisitions in the life insurance industry have had a beneficial effect on efficiency.     

Financing risk transfer under governance problems: Mutual versus stock insurers

Mutual insurance companies and stock insurance companies are different forms of organized risk sharing: policyholders and owners are two distinct groups in a stock insurer, while they are one and the same in a mutual. This distinction is relevant to raising capital and selling policies in the presence of frictional cost of capital. Free-rider and commitment problems in a stock insurer limit shareholders’ compensation for the frictional cost and therefore the level of capital that can be raised. By tying sales of policies to the provision of capital, the mutual form can overcome these problems at the cost of less diversified owners.     

The Underpricing of Insurance IPOs

The previous literature documents that insurance initial public offerings (IPOs) are less underpriced than those of noninsurance firms. This difference is usually attributed to lower information asymmetry for regulated firms. However, we find that once one controls for the file price adjustment insurance IPOs, both stock and mutual, are no less underpriced than other noninsurance offerings suggesting the book-building process resolves any such information asymmetries. We also find that mutual IPOs appear more underpriced than stock insurance IPOs, but this difference is related to the differences in pre-issue managerial ownership.     

Ironing out the kinks in executive compensation: Linking incentive pay to average stock prices

Traditional stock option grant is the most common form of incentive pay in executive compensation. Applying a principal-agent analysis, we find this common practice suboptimal and firms are better off linking incentive pay to average stock prices. Among other benefits, averaging reduces volatility by about 42%, making the incentive pay more attractive to risk-averse executives. Holding the cost of the option grant to the firm constant, Asian stock options are more cost effective than traditional stock options and provide stronger incentives to increase stock price. More importantly, the improvement is achieved with little impact on the option grant’s risk incentives (after adjusting for option cost). Finally, averaging also improves the value and incentive effects of indexed stock options.     

The Wealth and Information Effects of Insurers' Open Market Stock Repurchase Announcements

This article examines the use of an increasingly popular method of cash disbursement in the insurance industry: stock repurchase programs. Using a sample of stock repurchase announcements between 1981 and 1997, we examine the motivation for stock repurchase, estimate the market reaction to the repurchase announcement, and evaluate the magnitude of the reaction as it relates to particular insurance industry and firm characteristics. We examine the abnormal returns around the announcement day and find a significant positive wealth effect associated with repurchase announcements—a result that is consistent with that of other studies of both nonfinancial and financial firms. However, we suspect that the nature of the insurance product and the highly regulated status of the insurance industry might serve to mitigate the magnitude of an announcement effect. In fact, we find that the effect for all insurers is smaller than that obtained in samples of industrial firms. Finally, we examine the relationships between the magnitude of the announcement effect and various firm characteristics and test the significance of information signaling and Jensen's free cash flow theories in the insurance setting.     

Managerial Risk-Taking Incentives and Executive Stock Option Repricing: A Study of US Casino Executives

I examine the relation between managerial incentives from holdings of company stock and options and stock option repricing. Because options provide incentives to increase both risk and stock price, firms must realize that as options go underwater, executives might face incentives to invest in risky, negative NPV projects. Repricing may alleviate such incentives. I examine repricing activity by firms in the US gaming industry and find that risk-taking incentives from options are positively related to the incidence of executive option repricing. The results support the hypothesis that repricing assists firms in alleviating excessive risk-taking incentives of senior management.     

Life insurance companies as investment managers: New implications for consumers

This paper examines the attractiveness of the equity portfolios of life insurance companies as an alternative investment to mutual funds. In particular, this study analyzes the risk-adjusted investment performance of the stock portfolios of life insurance companies, attributable to their stock selection and market timing abilities. Using conventional measures of risk-adjusted portfolio performance, we find that life insurance companies exhibit performance similar to mutual funds. The evidence suggests that the life insurance companies, like their mutual fund counterparts, fail to exhibit differential stock selection or market timing abilities that are statistically significant. While the risk-adjusted investment performance of the two investment vehicles is similar, the variable annuity contracts of life insurance companies may offer an edge over mutual funds due to their ability to defer taxes.     

CEO incentives and the cost of debt

Motivated by concerns that stock-based compensation might lead to excessive risk-taking, this paper’s main purpose is to examine the relations between CEO incentives and the cost of debt. Unlike prior research, this paper uses the sensitivities of CEO stock and option portfolios to stock price (delta) and stock return volatility (vega) to measure CEO incentives to invest in risky projects. Higher delta (vega) is predicted to be related to lower (higher) cost of debt. The results show that yield spreads on new debt issues are lower for firms with higher CEO delta and are unrelated to CEO vega. The results also show that yield spreads are higher for firms whose CEOs hold more shares and stock options. In sum, the results suggest that both percentage-ownership and option sensitivity variables are important in understanding relations between CEO incentives and the cost of debt.     

Risikomessung unter Solvency II

With the enlargement of the European Union in 2005 several countries with a particularly low level of corporate taxation entered the Single Market. Big differences in taxation provide an incentive for insurance companies to shift their business activity into countries with low taxation. This incentive is aggravated by falling transport costs for insurance products over the last decade. This paper outlines the main factors driving the location choice of firms in an agglomeration model and presents additional, tax- and insurance business-related factors. Due to the peculiar production process in the insurance industry this industry is especially well suited for an empirical test of the efficacy of tax-related incentives to shift production abroad. The shifting of value added across borders is usually associated with cover up costs. In the insurance industry profit shifting can be done at high volume and low costs through reinsurance at foreign subsidiaries. This paper tests the hypothesis that differences in taxation induce a shift of business activity into low tax countries indirectly by estimating a model for Austrian data on international trade with insurance services.     

Convergence and risk-return linkages across financial service firms

We examine the risk and return linkages across US commercial banks, securities firms, and life insurance companies during the 1991–2001 period. After controlling for changes in the broader stock market, interest rates, and foreign currency values, we find that return and risk interdependencies across these financial firms are significant and size-varying; larger institutions display stronger volatility transmission linkages, while smaller ones exhibit more prominent return-related linkages. The tighter link in risk among large financial institutions (FIs) suggests stronger convergence, employment of common models of risk measurement and risk management, and more intense inter-industry competition, particularly between large banks and large securities firms, compared to smaller institutions. Lack of risk spillover among smaller FIs confirms the intuition that they typically assume more localized and idiosyncratic risk. The co-movement of stock returns among smaller FIs has been helped by the effects of locally based factors, such as economic conditions and state regulations, on all such institutions, and a less diversified product set. Differences in spillover patterns between large and smaller institutions have implications on investment choices and mergers and acquisitions in the industry. Introduction of the Gramm-Leach-Bliley Act (1999) has had dissimilar effects on the riskiness of large versus smaller life insurance and securities firms, and an insignificant effect on commercial banks.     

Actuarial Surplus Management in United Kingdom Life Insurance Firms

This study uses 1991–99 data gathered from the United Kingdom's life insurance industry to test empirically the notion that the reported annual surplus of a life insurer may be influenced by four firm‐specific characteristics: namely, reinsurance, output mix, organizational form and firm size. Consistent with expectations, the results indicate that the annual reported surplus is positively related to reinsurance and firm size and negatively related to the degree of product diversification. Contrary to our expectations, however, we find no evidence that proprietary (stock) life insurers tend to report higher annual surpluses than mutual life insurers.     

Do U.S. Insurance Firms Offer the “Wrong” Incentives to Their Executives?

We examine the relation between executive compensation and market‐implied default risk for listed insurance firms from 1992 to 2007. Shareholders are expected to encourage managerial risk sharing through equity‐based incentive compensation. We find that long‐term incentives and other share‐based plans do not affect the default risk faced by firms. However, the extensive use of stock options leads to higher future default risk for insurance firms. We argue that this is because option‐based incentives induce managerial risk‐taking behavior, which seeks to maximize managerial payoff through equity volatility. This could be detrimental to the interests of shareholders, especially during a financial crisis.
