Bank shareholder wealth effects of California's proposition 103

Proposition 103, approved by California voters on November 8, 1988, allows California state-chartered banks to become vendors of life, health, and property-liability insurance products. It is hypothesized that such a regulatory realignment should have resulted in a wealth increase for California state-chartered banks. An examination of the market response among these banks indicates a statistically significant positive stock price response on the dates of passage of Proposition 103 and a subsequent Supreme Court ruling upholding its constitutionality.     

Political Cost Incentives for Managing the Property-Liability Insurer Loss Reserve

This paper examines the effect of rate regulation on the management of the property-liability insurer loss reserve. The political cost hypothesis predicts that managers make accounting choices to reduce wealth transfers resulting from the regulatory process. Managers may under-state reserves to justify lower rates to regulators. Alternatively, managers may have an incentive to report loss inflating discretionary reserves to reduce the cost of regulatory rate suppression. We find insurers over-state reserves in the presence of stringent rate regulation. Investigating the impact along the conditional reserve error distribution, we discover that a majority of the response occurs from under-reserving firms under-reserving less because of stringent rate regulation.     

The Effective Duration and Convexity of Liabilities for Property-Liability Insurers Under Stochastic Interest Rates

Managing interest rate risk for property-liability insurers requires appropriate measurement of the sensitivity of liabilities to movements in interest rates. Most prior studies have assumed that interest rates shift in a parallel fashion and that the cash flows from liabilities are unaffected by interest rate changes. This article recognizes that unpaid property-liability (P-L) insurance losses are inflation-sensitive, that movements in interest rates will affect future claim payouts due to the correlation between interest rates and inflation and that interest rates are stochastic. The effective duration and convexity of P-L insurance liabilities calculated based on this approach are substantially lower than those measured using traditional approaches, which has important implications for asset-liability management by P-L insurers.     

Conversion and Efficiency Performance Changes: Evidence from the U.S. Property-Liability Insurance Industry

This study investigates whether the conversion of U.S. property-liability insurers improves their efficiency performance before and after the conversion. We estimate relative efficiency of converting insurers and control insurers using data envelopment analysis. The Malmquist analysis is also used to measure changes in efficiency pre- and post-conversion. The evidence shows that converting insurers experience larger gains in cost efficiency and total productivity change than mutual control insurers before conversion. In addition, the empirical results indicate that converting insurers improve efficiency after conversion. These results are robust with respect to both the value-added and the financial intermediary approaches. The overall results support the efficiency hypothesis proposed by Mayers and Smith (1986).     

Determinanten der Liquidität in der deutschen Schaden- und Unfallversicherungsindustrie: Bedeutung,Erklärungskraft und Auswirkung der Finanzkrise

The aim of this paper is to analyze the corporate liquidity and its determinants for the German property-liability insurance industry using company-level data for the period 2002–2014. We first investigate the differences in cash holdings across insurers. We then quantify the relative importance of firm-level determinants compared with macroeconomic determinants in explaining insurers’ cash holding choices. In addition, we examine whether the financial crisis of 2008 has an impact on the liquidity situation of insurers. Our results indicate that cash holdings vary significantly across German property-liability insurers. The firm-level determinants size, group affiliation and reinsurance utilization explain more than 50% of the variation. We also find that macroeconomic conditions appear to have negligible effects on the liquidity situation of insurers. In addition, we do not find evidence that the liquidity of German property-liability insurers is influenced by the financial crisis of 2008. The proportion of cash remains relatively stable at 6% of the total assets.     

Internal Versus External Capital Markets in the Insurance Industry: The Role of Reinsurance

This study compares internal and external sources of capital in the insurance industry by analyzing reinsurance activity between affiliated and unaffiliated insurers. Tests are performed using data from a large sample of property-liability insurers that are affiliated with at least one other property-liability insurer. Results indicate that while demands for internal and external reinsurance have some factors in common, there are cost-based differences in internal and external capital, as well as structural differences in the use of internal and external reinsurance. Results are consistent with previous theories related to internal versus external capital markets.     

Considerations of cost trade-offs in insurance solvency surveillance policy

We propose a process for identifying potentially insolvent insurers on a cost-effective basis. A loss cost function is developed such that the effectiveness of monitoring is maximized relative to a cost constraint. The loss cost function is supported by a model that provides a rank ordering of financial institutions according to their probability of insolvency. When tested against a full sample of property-liability insurance companies , the procedure provides information critical to maximizing the effectiveness of regulatory resources available for solvency surveillance and performs well as a predictor of insolvency. Likewise, the rank ordering of insurers overcomes an estimation problem critical to establishing risk-adjusted guaranty assessments.     

Mergers &; Acquisitions,Diversification and Performance in the U.S. Property-Liability Insurance Industry

This paper examines the relationship between mergers & acquisitions (M & As), diversification and financial performance in the U.S. property-liability insurance industry over the period 1989–2004. The risk-adjusted return on assets (ROA), return on equity (ROE), Z-score and total risk measured by earnings volatility are considered as a relevant indicator of performance. We find that acquirers’ financial performance decreases and earnings volatility increases during the gestation period after the M & As perhaps due to increased frictional costs associated with post-merger integration and agency problems. We find that more focused insurers outperform the product-diversified insurers, implying that the costs of diversification outweigh the benefits. These findings are robust to alternative risk and diversification measures. We also find that marginal increases in commercial line share are associated with higher risk-adjusted profits, but these gains are offset by the extra costs from product diversity when its initial share is low. For insurers initially concentrated in commercial line, a marginal increase in commercial line share is related to higher performance due to positive effects of both direct exposure and indirect focus.     

Effects of Risk Management on Cost Efficiency and Cost Function of the U.S. Property and Liability Insurers

Abstract

This paper adopts the one-step stochastic frontier approach to investigate the impact of risk management tools of derivatives and reinsurance on cost efficiency of U.S. property-liability insurance companies. The stochastic frontier approach considers both the mean and variance of cost efficiency. The sample includes both stock and mutual insurers. Among the findings, the cost function of the entire sample carries the concavity feature, and insurers tend to use financial derivatives for firm value creation. The results also show that for the entire sample the use of derivatives enhances the mean of cost efficiency but accompanied with larger efficiency volatility. Nevertheless, the utilization of financial derivatives mitigates efficiency volatility for mutual insurers. This research provides important insights for the practice of risk management in the property-liability insurance industry.     

The Market Valuation and Trading Volume Effects of the Creation of the Florida Hurricane Catastrophe Fund on Property-liability Insurers

The Florida Hurricane Catastrophe Fund was officially created in November, 1993. This study analyzes investor reactions during the creation of the Florida Hurricane Catastrophe Fund. We find significant share price reactions for four of six legislative events consistent with the predictions of the theory outlined. We use both a generalized least squares portfolio approach and Corrado's (1989) rank statistic, a nonparametric event study methodology, to arrive at our findings. Empirical analysis of trading volume corroborates the findings involving share price reactions. We also find that the market is able to discriminate between property-liability insurers on the basis of hurricane exposure and firm size.     

Cash holdings between public and private insurers ‒ a partial adjustment approach

Cash holdings of financial institutions, especially private firms, have been understudied in existing literature. This paper fills that gap by examining the cash holdings of US property-liability insurers in order to analyze the difference in cash holdings and cash adjustments between public and private stock insurers and between mutual and stock insurers within the private insurer category. We find that public insurers hold much less cash than private stock insurers, which differs from the findings for non-financial firms. Additionally, we find that mutual insurers hold less cash than private stock insurers. Public insurers adjust their cash holdings much faster toward their target cash levels than private stock insurers do when facing an extreme cash shortfall, but their adjustment speed is indifferent from that of private stock insurers when both having excess cash. Mutual insurers are able to adjust cash holdings slightly faster than private stock insurers when there is an extreme cash shortfall but are indifferent in adjustment speed from private stock insurers when having excess cash in hand. Overall, our results are more consistent with the financing frictions hypothesis of cash holdings and are inconsistent with the owner-manager agency problems of free cash flow.     

Mergers and acquisitions in the US property-liability insurance industry: Productivity and efficiency effects

This paper analyzes the productivity and efficiency effects of mergers and acquisitions (M&As) in the US property-liability insurance industry during the period 1994–2003 using data envelopment analysis (DEA) and Malmquist productivity indices. We seek to determine whether M&As are value-enhancing, value-neutral, or value-reducing. The analysis examines efficiency and productivity change for acquirers, acquisition targets, and non-M&A firms. We also examine the firm characteristics associated with becoming an acquirer or target through probit analysis. The results provide evidence that M&As in property-liability insurance were value-enhancing. Acquiring firms achieved more revenue efficiency gains than non-acquiring firms, and target firms experienced greater cost and allocative efficiency growth than non-targets. Factors other than efficiency enhancement are important factors in property-liability insurer M&As. Financially vulnerable insurers are significantly more likely to become acquisition targets, consistent with corporate control theory, and we also find evidence that M&As are motivated to achieve diversification. However, there is no evidence that scale economies played an important role in the insurance M&A wave.     

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.     

New Risk-Based Capital Standards in the European Union: A Proposal Based on Empirical Data

In response to criticism concerning the current solvency system, the European Commission is developing new rules for insurance companies operating in the member states of the European Union (EU). Under this so-called Solvency II concept, an insurer is allowed to verify its solvency by using an internal risk management model previously approved by the regulatory authority. In this article we develop such an internal risk management approach for property-liability insurers that is based on dynamic financial analysis (DFA). The proposed concept uses a simulation technique and models the central risk factors from the investment and underwriting areas of an insurance company. On the basis of the data provided by a German insurer, the ruin probabilities under different scenarios and varying planning horizons are calculated.     

Efficiency and Demutualization: Evidence From the U.S. Life Insurance Industry in the 1980s and 1990s

This article examines the efficiency changes of U.S. life insurers before and after demutualization in the 1980s and 1990s. We use two frontier approaches (the value‐added approach and the financial intermediary approach) to measure the efficiency changes. In addition, we use Malmquist indices to investigate the efficiency and productivity change of converted life insurers over time. The results using the value‐added approach indicate that demutualized life insurers improve their efficiency before demutualization. On the other hand, the evidence using the financial intermediary approach shows the efficiency of the demutualized life insurers relative to mutual control insurers deteriorates before demutualization and improves after conversion. The difference in the results between the two approaches is due to the fact that the financial intermediary approach considers financial conditions. The results of both approaches suggest that there is no efficiency improvement after demutualization relative to stock control insurers. There is, however, efficiency improvement relative to mutual control insurers when the financial intermediary approach is used.     

The Impact of Institutional Ownership on the Reinsurance Decision

Risk management has a central role in corporate America. Insurance companies frequently manage risk by purchasing reinsurance because it reduces the downside risk (i.e., bankruptcy risk) of an insurer. Because reinsurance is costly, Mayers and Smith (1990, Journal of Business , 63: 19-40) argue that reinsurance purchases should be negatively associated with the diversification of the owners' portfolios. Further, institutional owners play a significant role in equity markets yet we know little about their effect on firm behavior. The purpose of this study is to examine empirically the influence of institutional ownership on reinsurance for a sample of widely held property-liability insurers. We hypothesize that insurers with higher levels of institutional ownership purchase less reinsurance. Using a sample of 45 publicly traded property-liability insurers from 1995 to 1997, we demonstrate that the utilization of reinsurance decreases as the level of institutional ownership increases. This suggests that the diversification of the owners' portfolios is a determinant of the insurers' reinsurance decisions.     

中国财产保险市场结构、效率与绩效关系检验

运用B erger和Hannan(1993)模型对中国产险市场结构、效率与绩效关系实证检验得出,中国的产险市场既不是结构决定绩效,也不是效率决定绩效,市场力量假说和效率结构假说都不存在。但大企业存在一定程度的"安逸生活"特征。随着中国产险市场化的改革,产险市场将逐步从市场力量说向效率结构假设转化。     

Forestalling capital regulation or masking financial weakness? Evidence from loss reserve management in the property–liability insurance industry

This study examines the extent to which capital thresholds induce insurers to strategically exert accounting discretion to forestall regulatory actions. Using a sample of US property–liability insurers during 1994–2009, we find that when managing their claim loss reserves, the average insurers are insensitive to the pressure of capital regulation as measured by the distance of their RBC ratio to the action threshold. Yet, when the insurers are virtually partitioned by their reserving tendency, the effect of regulatory pressure is significantly related to the downward reserve bias in the under-reserving insurer cohorts. This finding continues to hold even after we utilize the number of ratio violations in the insurance regulatory information systems to purge the financial weakness effect embedded in the distance to RBC bound ratio. Hence, our empirical evidence suggests that insurers that are about to trigger the regulatory threshold will have the incentives to understate their loss reserves to preclude the impending authorized preventive actions. Finally, our analyses also shed light on the heterogeneity of incentives to managing loss reserves among over- and under-reserving insurers.     

Neue Wege in der Kapitalanlage: Die Symbiose zwischen Banken und Versicherungen im Bereich der ‚Alternative Assets‘

The current low interest rates pose a major challenge in particular for life insurers. The introduction of Basel III in the banking and Solvency II in the insurance sector will have major impacts on both industries. This paper provides insight into possible products supplied by banks, which offer the possibility for life insurers to invest in ‘alternative assets’, especially in infrastructure projects. The focus lies on investments in infrastructure loans. If these are placed in a SPV, which itself emits bonds, the lowest amount of regulatory equity capital for both, the bank and the insurance company is required.
