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

This article analyzes variations in line‐of‐business diversification status and extent among property–liability insurers. Our results show that the extent of diversification is not driven by risk pooling considerations; insurers operating in more volatile business lines do not diversify more. Diversification can rather be explained by the benefits of internal capital markets and barriers to business growth like market size and concentration. In our analysis, we distinguish between related and unrelated diversification. Using a measure of unrelated line‐of‐business diversification we find the first support for the diversification prediction of the managerial discretion hypothesis that mutual insurers should be less diversified than stock insurers. While mutual insurers tend to exhibit higher levels of total diversification, they engage in significantly less unrelated diversification than do stock insurers.     

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.     

Does one size fit all? Determinants of insurer capital structure around the globe

As financial markets become more global, the question arises whether any country specific considerations are still relevant for insurance companies’ capital structure. This research examines this question with firm-level data across a broad range of countries including those in developing markets. What we find is that the optimal capital structure of insurance companies is not homogeneous across countries. We find that country-level factors explain a substantial fraction of the cross-sectional variation in insurance companies’ capitalization levels. Our results add to the current policy discussion on global regulatory capital requirements. If insurer capital structure is not homogeneous across countries, a global capital standard – if desired – should take differences in the institutional environments across countries into account to avoid market distortions.     

Open‐Market Stock Repurchases by Insurance Companies and Signaling

The signaling hypothesis of share repurchases implies that management uses repurchases to signal either that their firm's future operating performance will improve or that shares of their stock are simply underpriced by the market. This study examines which of the two interpretations can better explain open‐market share repurchase programs announced by insurance companies. We find no evidence that future‐operating performance of insurers improves following the repurchase announcement. In addition, changes in future operating performance cannot explain the announcement‐period abnormal return. Instead, the stock undervaluation prior to the repurchase announcement can significantly explain the announcement‐period abnormal return, particularly for life insurers. Overall, our results suggest that the positive market reaction to insurers’ open‐market share repurchase announcements is due to the stock undervaluation by the market, but not due to positive information content about future operating performance conveyed in the repurchase announcement.     

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).     

The effect of predation risk on cash holdings: Empirical evidence from the U.S. property‐liability insurance industry

Corporate cash holdings play a significant role in the U.S. property‐liability insurance industry yet the topic of insurer cash holdings policy has largely been overlooked by prior empirical research. While a number of studies have investigated firm‐specific factors related to cash holdings in the insurance industry, prior research has not examined how market concentration and potential predation risk impact cash holdings. We propose a new measure of market concentration and provide evidence in support of the predation risk theory. Specifically, we show that insurers exposed to more concentrated markets tend to hold more cash. Furthermore, the relation between market concentration and cash holdings is influenced by access to internal capital. While unaffiliated insurers without access to internal capital hold greater levels of cash in more concentrated markets, group insurers with access to internal capital do not hold greater levels of cash to mitigate predation risk.     

The Market Structure–Performance Relationship in the International Insurance Sector

This article tests the applicability of the structure–conduct–performance (SCP) hypothesis in the international nonlife insurance marketplace. We employ a panel data regression methodology that includes 23 nations (developed and developing countries) over the time period of 1996 to 2003. The results reveal that the interaction of market liberalization and market concentration shares a complex relationship with market profitability. Our results show that the expectations associated with the SCP hypothesis are supported when the levels of liberalization are low. However, for markets that are highly liberalized the presence of foreign insurers significantly alters the dynamics of nonlife insurance markets.     

Risk,Capital, and Operating Efficiency: Evidence from Taiwan’s Life Insurance Market

ABSTRACT

In this article, we investigate the relationships among risk, capital, and operating efficiency for Taiwanese life insurance companies from 2004 to 2009 by using the two-stage least-square approach. We find a positive relation between inefficiency and product risk. At the same time, efficient insurers are seen as taking higher asset risk than inefficient insurers. A contrasting finding also shows that the relationship between capital and product risk is positive, while the relationship between capital and asset risk is negative. Moreover, we present a negative relationship between inefficiency and capital level, indicating that well-capitalized insurers operate more efficiently than poorly capitalized insurers.     

The Impact of Sovereign Wealth Funds on Corporate Value and Performance

The last few years have seen a remarkable increase in the participation of sovereign wealth funds (SWFs) in global capital markets. In this article, the author draws on a unique dataset of SWF international holdings—one that dates back to the year 2002 and includes individual SWF holdings in more than 8,000 companies in 58 countries—to provide evidence of the impact of SWFs on corporate values and operating performance. Contrary to claims that SWFs expropriate minority investors and pursue political agendas, the main finding of the author's study is that SWF ownership is associated with positive changes in both corporate market values and operating returns. In support of these findings, the author also identifies three important ways that SWFs work to increase the performance and value of the companies they invest in: (1) as long‐term holders that provide a stable source of financing; (2) as representatives of deep pools of international capital in search of global diversification opportunities that are likely to provide companies with a lower‐cost (as well as more “patient”) source of equity capital; and (3) as politically well‐connected strategic investors that enable their companies to leverage important connections when accessing new product markets.     

The Determinants of Financial Health of Asian Insurance Companies

Previous studies of financial health of insurance companies are mainly focused on insurers operating in the United States and developed economies. This article focuses on the solvency of general (property‐liability) and life insurance companies in Asia using firm data and macro data separately. It uses different classification methods to classify the financial status of both general and life insurance companies. With the exception of Japan, failures of insurers in Singapore, Malaysia, and Taiwan are nonexistent. We find that, first, the factors that significantly affect general insurers' financial health in Asian economies are firm size, investment performance, liquidity ratio, surplus growth, combined ratio, and operating margin. Second, the factors that significantly affect life insurers' financial health are firm size, change in asset mix, investment performance, and change in product mix, but the last three factors are more applicable to Japan. Third, the financial health of insurance companies in Singapore seems to be significantly weakened by the Asian Financial Crisis. As the insurance industry in different Asian economies is at different stages of development, they require different regulatory guidelines.     

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.     

Cost efficiency and board composition under different takaful insurance business models

This study examines the link between cost efficiency and board composition in non-life takaful insurance firms operating in 17 Islamic countries using panel data for 2004–2007. Nonparametric data envelopment analysis (DEA) is used to compute cost efficiency scores and a second-stage logit transformation regression model is then employed to test the influence of corporate characteristics on these efficiencies. We find that average levels of cost efficiency in takaful insurance markets mirror the efficiency in developed non-life insurance markets. The relative influence of board composition, such as the proportion of non-executive directors on the board, on the cost efficiency of takaful insurers depends on its interaction with other firm-specific characteristics such as board size. Hence, the effect of corporate governance systems on the cost efficiency of takaful insurers can be complicated by various firm-specific factors. Our results could have important commercial and policy implications.     

GOLBALIZATION, CORPORATE FINANCE, AND THE COST OF CAPITAL

International financial markets are progressively becoming one huge, integrated, global capital market—a development that is contributing to higher stock prices in developed as well as developing economies. For companies that are large and visible enough to attract global investors, having a global shareholder base means having a lower cost of capital and hence a greater equity value for two main reasons: First, because the risks of equity are shared among more investors with different portfolio exposures and hence a different “appetite” for bearing certain risks, equity market risk premiums should fall for all companies in countries with access to global markets. Although the largest reductions in cost of capital resulting from globalization will be experienced by companies in liberalizing economies that are gaining access to the global markets for the first time, risk premiums can also be expected to fall for firms in long-integrated markets as well. Second, when firms in countries with less-developed capital markets raise capital in the public markets of countries (like the U.S.) with highly developed markets, they get more than lower-cost capital; they also import at least aspects of the corporate governance systems that prevail in those markets. For companies accustomed to less-developed markets, raising capital overseas is likely to mean that more sophisticated investors, armed with more advanced technologies, will participate in monitoring their performance and management. And, in a virtuous cycle, more effective monitoring increases investor confidence in the future performance of those companies and so improves the terms on which they raise capital. Besides reducing market risk premiums and improving corporate governance, globalization also affects the systematic risk, or “beta,” of individual companies. In global markets, the beta of a firm's equity depends on how the stock contributes to the volatility not of the home market portfolio, but of the world market portfolio. For companies with access to global capital markets whose profitability is tied more closely to the local than to the global economy, use of the traditional Capital Asset Pricing Model (CAPM) will overstate the cost of capital because risks that are not diversifiable within a national economy can be diversified by holding a global portfolio. Thus, to reflect the new reality of a globally determined cost of capital, all companies with access to global markets should consider using a global CAPM that views a company as part of the global portfolio of stocks. In making this argument, the article reviews the growing body of academic studies that provide evidence of the predictive power of the global CAPM as well as the reduction in world risk premiums.     

Estimating the Cost of Equity for Property-Liability Insurance Companies

Due to the highly skewed and heavy‐tailed distributions associated with the insurance claims process, we evaluate the Rubinstein‐Leland (RL) model for its ability to improve the cost of equity estimates of insurance companies because of its distribution‐free feature. Our analyses show that there is as large as a 94‐basis‐point difference in the estimated cost of insurance equity between the RL model and the capital asset pricing model (CAPM) for the sample of property‐liability insurers with more severe departures from normality. In addition, consistent with our hypotheses, significant differences in the market risk estimates are found for insurers with return distributions that are asymmetrically distributed, and for small insurers. Third, we find significant performance improvements from using the RL model by showing smaller values of excess return of the expected return of the portfolio to the model return for a portfolio of insurers with returns that are more skewed and for a portfolio of small insurers. Finally, our panel data analysis shows the differences in the market risk estimates are significantly influenced by firm size, degree of leverage, and degree of asymmetry. The implication is that insurers should use the RL model rather than the CAPM to estimate its cost of capital if the insurer is small (assets size is less than $2,291 million), and/or its returns are not symmetrical (the value of skewness is greater than 0.509 or less than ?0.509).     

The Capital Structure of Firms Subject to Price Regulation: Evidence from the Insurance Industry

Automobile and workers' compensation insurance are relatively homogeneous products sold under varying regulatory systems among the states. This paper investigates how price regulation affects the capital structure decisions of profit-maximizing insurers who sell insurance in both competitive and/or regulated markets. Specifically, we test the hypothesis that insurers subject to price regulation will choose to hold less capital. In addition, we hypothesize insurers subject to more stringent regulatory pricing constraints will choose even higher degrees of leverage because the benefits of holding additional amounts of capital are suppressed. We conduct empirical tests using cross-sectional data on insurers and find evidence consistent with both hypotheses. These findings have important implications for insurance price and solvency regulation. Stricter price regulation increases the default risk (i.e., reduces the financial quality) of insurance contracts purchased by individuals and firms.     

Solvency Ⅱ与C-ROSS非寿险保险风险最低资本要求比较研究——基于中国60家财产保险公司的经验证据

本文以非寿险业务保险风险最低资本要求为考察对象,研究了欧盟Solvency Ⅱ与中国C-ROSS的差异,并利用中国保险市场60家财险公司的经验数据,对两者之间的差异进行了实证和模拟分析。研究结果表明,Solvency Ⅱ和C-ROSS对中国财险公司保险风险最低资本要求存在差异。对于拥有传统业务结构的财险公司,Solvency Ⅱ对保险风险最低资本要求更高,但是这种差距随着公司业务规模的缩小而减弱;对于以经营某些专业险种为主的财险公司,主营业务险种对两者差异具有决定性影响。本文的研究结论详细解释了Solvency Ⅱ与C-ROSS在非寿险保险风险最低资本计算上的异同,对C-ROSS下一步的修订工作提供了一定的支持与参考。     

Determinants of Sovereign Wealth Fund Cross‐Border Investments

Using a sample of 1,590 purchases of stock by sovereign wealth funds (SWFs) in listed firms in 78 target countries between 1985 and 2011, we study the country‐level determinants of SWF cross‐border investment. We find that SWFs from countries with high levels of openness and economic development, but with less developed local capital markets, will make more cross‐country transactions, while target countries with higher levels of investor protection and more developed capital markets will attract more SWF investment. Our findings support the investment facilitation hypothesis, suggesting that SWFs act purely or principally as commercial investors facilitating cross‐border corporate investment.     

When Do International Operations Lead to Improved Performance? An Analysis of Property‐Liability Insurers

In recent decades, insurers have been increasing their exposure to international markets. This article seeks to investigate the relationship between property-liability insurers' international operations and their risk-adjusted returns using cross-section and time-series data for the years 1992 through 2000. Our findings indicate that the relationship between international operations and performance is contingent upon the degree of product diversification. Insurance companies with focused operations in terms of product lines achieve higher risk-adjusted performance as they increase their exposures to international markets. However, insurers who are highly diversified across product lines face declining returns with greater exposure to international markets.     

Managing the risks of energy efficiency insurances in a portfolio context: An actuarial diversification approach

To achieve ambitious international climate goals, an increase of energy efficiency investments is necessary and, thus, a growing market potential arises. Concomitantly, the relevance of managing the risk of financing and insuring energy efficiency measures increases continuously. Energy Efficiency Insurances encourage investors by guaranteeing a predefined energy efficiency performance. However, literature on quantitative analysis of pricing and diversification effects of such novel insurance solutions is scarce. This paper provides a first approach for the analysis of diversification potential on three levels: collective risk diversification, cross product line diversification, and financial hedging. Based on an extensive real-world data set for German residential buildings, the analysis reveals that underwriting different Energy Efficiency Insurance types and constructing Markowitz Minimum Variance Portfolios halves overall risk in terms of standard deviation. We evince that Energy Efficiency Insurances can diversify property insurance portfolios and reduce regulatory capital for insurers under Solvency II constraints. Moreover, we show that Energy Efficiency Insurances potentially supersede financial market instruments such as weather derivatives in diversifying property insurance portfolios. In summary, these three levels of diversification effects constitute an additional benefit for the introduction of Energy Efficiency Insurances and may positively impact their market development.     

Social Capital,Trust, and Corporate Performance: How CSR Helped Companies During the Financial Crisis (and Why It Can Keep Helping Them)

The authors summarize the findings of their study, published recently in the Journal of Finance, that shows that CSR investments can help companies when they perhaps need it most—that is, during sharp downturns when overall trust in companies and markets declines. Companies with high‐CSR rankings experienced stock returns that were five to seven percentage points higher than their low‐CSR counterparts during the 2008–2009 financial crisis, and even larger excess returns during the Enron crisis of 2001–2003. High‐CSR companies during the crisis also reported better operating performance, higher growth, higher employee productivity, and greater access to debt markets—while continuing to generate higher shareholder returns as late as the end of 2013. Many of these operating improvements continued well into the post‐crisis period, though at more modest levels. As the authors view their findings, the ‘social capital’ built up by corporate CSR programs complements effective financial capital management in increasing shareholder wealth mainly by limiting companies' downside risk. CSR is seen as not only reducing systematic as well as firm‐specific risk, but as also providing protection against overall ‘loss of trust.’ The social capital created by CSR programs is said to provide a kind of insurance policy that pays off when investors and the overall economy face a severe crisis of confidence.
