Capital structure under collusion

We analyze the financial leverage of firms that collude to soften product market competition by forming a cartel. We find that cartel firms have lower leverage during collusion periods. This is consistent with the idea that cartel firms strategically reduce leverage to make their cartels more stable, because high leverage makes deviations from a cartel agreement more attractive. Given that cartels have a large economic footprint, their study is also relevant for the capital structure literature, which has largely ignored the role of anti-competitive behavior.     

The Role of Tax Subsidies in the Market for Health Insurance

This paper investigates the role of tax subsidies in linking the market for health insurance to the employment relationship. Using both American and Canadian data, it investigates how these subsidies influence whether health insurance coverage is offered in different sized firms and whether it is offered through an employer versus the individual private market. The findings indicate that tax subsidies encourage the provision of insurance in smaller firms. Removal of the subsidies would cause the level of insurance in small firms to decline significantly, but would not cause a large change in the level of insurance in larger firms. Part of this decline would be offset by increases in the market for individually purchased insurance.     

Empirical Evidence for Advantageous Selection in the Commercial Fire Insurance Market

De Meza and Webb (2001) indicated that individuals with a higher degree of risk aversion would demand more insurance and invest in self-protection to reduce risk probability when both the preference type and investment in self-protection are hidden from insurers. They referred to the negative correlation between market insurance and risk type as advantageous selection. However, the relationship between risk type and the degree of risk aversion is debatable in both theoretical and empirical research. This paper therefore proposes that advantageous selection could be supported from another angle by directly examining the relationships that exist among market insurance, self-protection, and risk probability. By focusing on the commercial fire insurance market, information on the purchase of market insurance, investment in self-protection, and fire accident records is hand-collected by means of a unique survey. It is found that firms purchasing market insurance have a greater tendency to channel efforts into self-protection. It is also found that firms expending effort on self-protection are less likely to suffer a fire accident. Furthermore, it is found that firms with commercial fire insurance have less chance of suffering a fire accident than those without such insurance. Each of the above three findings jointly supports the view that advantageous selection could play a critical role in the commercial fire insurance market.     

The risk implications of insurance securitization: The case of catastrophe bonds

Catastrophe (Cat) bonds are insurance securitization vehicles which are supposed to transfer catastrophe-related underwriting risk from issuers to capital markets. This paper addresses key, unanswered questions concerning Cat bonds and offers the following results. First, our findings show firms that issue Cat bonds exhibit less risky underwriting portfolios with less exposure to catastrophe risks and overall less need to hedge catastrophe risk. These results show that the access to the market for insurance securitization is easiest for firms with less risky portfolios. Second, firms that issue Cat bonds are found to experience a reduction in their default risk relative to non-issuing firms and our results, therefore, demonstrate that Cat bonds provide effective catastrophe hedging for issuing firms. Third, firms with less catastrophe exposure, increase their catastrophe exposure following an issue. Therefore, our paper cautions that the ability to hedge catastrophe risk causes some firms to seek additional catastrophe risk.     

The Impact of the Health Insurance Market on Small Firm Employment

Small firms that offer health insurance to their employees may face variable premiums if they hire employees with high expected health costs. To avoid expensive premium variability, small firms may attempt to maintain a workforce with low expected health costs. This results in employment distortions. I examine the magnitude of these employment distortions using the 1987 National Medical Expenditure Survey and the 1996 Medical Expenditure Panel Survey. Based on the underwriting behavior of insurance companies in 1988, I classify medical conditions into three categories: conditions that led to denial of coverage; conditions that led to exclusion restrictions; and, conditions that led to higher premiums. In 1987, I find that insured small firms were less likely to employ workers with families that had conditions that led to higher premiums than insured large firms. However, in 1996, possibly due to the passage of small group health insurance reforms that restrict insurers' ability to exclude or deny coverage, insured small firms were less likely to employ workers with denial conditions compared to insured large firms. These results suggest that the pattern of employment distortions in insured small firms is consistent with the evolving small group health insurance market.     

Strategic Demand for Insurance

We focus on the corporate demand for insurance under duopoly. We consider the case in which firms purchase insurance in order to enhance their competitiveness. We show that a higher level of corporate insurance makes a firm more aggressive and its competitor less aggressive in the output market (strategic effect). The optimal coverage of insurance is determined by comparing the strategic effect of insurance and the cost of insurance. The optimal coverage is positive if the strategic effect is greater than the cost of insurance. An interesting implication is that a risk‐neutral firm may purchase actuarially unfair insurance. The main strategic effect of insurance comes from the fact that firms purchase insurance before they produce outputs. Insurance makes firms more aggressive due to the limited risk costs of firms.     

An Empirical Investigation of Market Structure, Efficiency, and Performance in Property-Liability Insurance

This study examines the relationships among market structure and performance in property‐liability insurers over the period 1992–1998 using data at the company and group levels. Three specific hypotheses are tested: traditional structure‐conduct‐performance, relative market power, and efficient structure (ES). The results provide support for the ES hypothesis. The ES hypothesis posits that more efficient firms can charge lower prices than competitors, enabling them to capture larger market shares and economic rents, leading to increased concentration. Both revenue and cost efficiency are used in the analysis, and this is the first study to use revenue efficiency in this type of analysis. The results for the sample period as a whole and by year are consistent. The overall results suggest that cost‐efficient firms charge lower prices and earn higher profits, in conformance with the ES hypothesis. On the other hand, prices and profits are found to be higher for revenue‐efficient firms. Revenue X‐efficiency is derived from activities such as cross‐selling and may rely heavily on the use of detailed information from customer databases to identify potential customers. The implications of this research are that regulators should be more concerned with efficiency (both cost and revenue) rather than the market power that arises from the consolidation activity taking place in insurance.     

The Impact of the European Union Insurance Directives on Insurance Company Stocks

This article examines the impact of the passage of the Second and Third Life and Non‐Life European Insurance Directives on insurance firms located in 14 European Union countries, Norway, and Switzerland. The third directives have a wealth effect on the European insurance market, while the second directives do not. The Third Life Directive resulted in a wealth increase for the European insurance market, while the Third Non‐Life Directive had a modest negative wealth effect. The wealth effects differ at both the country and firm level. The directives have differential impacts on firms depending on the firms’ characteristics and those of the market they operated in prior to the directives. Regression results indicate that the second directives have impacted firms in protected markets negatively, especially those with higher debt and higher returns on assets. At the time of the third directives, insurance firms benefited, even those in previously protected markets, indicating that firms may have positioned themselves in preparation for the liberalization of the laws.     

Collusion under monitoring of sales

Collusion under imperfect monitoring is explored when firms' prices are private information and their quantities are public information; such an information structure is consistent with several recent price‐fixing cartels, such as those in lysine and vitamins. For a class of symmetric oligopoly games, it is shown that symmetric equilibrium punishments cannot sustain any collusion. An asymmetric punishment is characterized that does sustain collusion and it has firms whose sales exceed their quotas compensating those firms with sales below their quotas. In practice, cartels could have performed such transfers through sales among the cartel members.     

Product market pricing power, industry concentration and analysts’ earnings forecasts

This is the first study to establish a link between product market power and analysts’ earnings forecast accuracy and bias. Relating two different dimensions of market power to earnings forecastability, we document that (a) a firm’s relative pricing power and (b) its industry concentration are strong positive determinants of analysts’ earnings forecast accuracy. We find that forecasting earnings of higher market power firms is less complex due to their ability to withstand cost shocks as well as greater informational-efficiency enjoyed by such firms. Further, forecast optimism increases with weakening product market pricing power and with lower industry concentration. The knowledge derived from this study will hopefully improve the accuracy of equity valuation, and thereby engender better buy-side (stock selections) and sell-side recommendations by analysts. Our analysis also suggests that brokerage firms compensating analysts based on forecast accuracy need to adjust for the differential in the information complexity of different industries.     

The strategic use of corporate insurance in China

We use the agency theory to conduct a novel test of the strategic use of property insurance in China's corporate sector. With regard to our main test hypotheses, we find that the incidence of property insurance purchased is directly related to the degree of product–market competitiveness, and positively related to market liquidity and firms’ growth opportunities. However, the homogeneity of market operations is not statistically significant. In our second-stage Cragg regression, market liquidity becomes insignificant while firms’ growth opportunities are now inversely related to the amount of insurance purchased. Additionally, the homogeneity of market operations becomes significantly related to the corporate purchase of property insurance. Therefore, different factors (e.g. cost considerations) may influence the decisions to purchase property insurance and subsequently, the level of coverage provided. We argue that our results are relevant for companies in other emerging markets such as Eastern Europe and companies operating in more developed Western economies such as the European Union (EU).     

Impact of Underwriting Cycles on the Solvency of an Insurance Company

Abstract

This paper studies the solvency of an insurance firm in the presence of underwriting cycles. A small or medium-size insurance company with a price-taker position in the market is considered. Its premium income is assumed to obey an autoregressive process with cycles. Specifically, the premium income for a specific calendar year is influenced by the market experience for the last couple years. Under this classical AR(2) dynamics governing the premium income, an explicit expression for the ultimate ruin probability is derived, using a martingale approach, in the lighttailed claims case. Furthermore, the logarithmic asymptotic behavior of the ultimate ruin probability as well as the typical path to ruin are investigated. Then a comparison is made with the classical case where the same company operates on a market without such cycles. Asymptotically, the presence of market cycles is shown to increase the risk for the company. Numerical illustrations are performed on Canadian motor insurance market data and support the theoretical analysis.     

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.     

The impact of D&O insurance on excess corporate leverage

The governance effects of directors’ and officers’ liability insurance (D&O insurance), an important tool for risk diversification, are of strong concern in the capital market. Using a sample of Chinese A-share listed firms from 2009 to 2018, we examine the impact of D&O insurance on excess corporate leverage. We find that D&O insurance is negatively associated with excess corporate leverage and that this result is consistent with a series of robustness tests. Further analyses show that D&O insurance impedes excess corporate leverage mainly because of its effect on external monitoring. The effect is more pronounced for firms that are state-owned, have political connections and are located in provinces with low marketization than for other firms.     

Distributive inefficiency in horizontal mergers: Evidence from wealth transfers between merging firms and their customers

The ultimate goal of antitrust enforcement is to maximize the surplus consumers enjoy by enhancing production efficiency and eliminating market power. Previous literature focuses on the average net wealth effects on merging firms and their stakeholder firms and reports evidence of efficiency gains while no evidence of market power in horizontal mergers. In this paper, we examine how efficiency gains distribute between the merging firms and their customer firms. We find a significant negative relation between the combined abnormal returns on the merging firms and those on their customer firms, demonstrating a wealth transfer effect. Such a negative relation is more pronounced when market power is likely to be more intensive. On average, the merging firms gain, and their customers do not lose. Our results suggest that market power allows merging firms to withhold merger gains that would have been passed to the downstream under perfect competition and prevents customers from enjoying the whole consumer surplus. Distributive inefficiency exists in horizontal mergers.     

The Market for Directors’ and Officers’ Insurance

Directors’ and officers’ (D&O) liability insurance is a commonly used risk management tool for corporations both in the United States and abroad. While prior research has focused on the demand for D&O insurance and its role in corporate governance, there is an absence of literature on the supply side of the D&O market. Using the newly available D&O Insurance Coverage Supplement to insurers’ statutory filings, we develop a more comprehensive understanding of the D&O insurance market and of those firms that write D&O coverage. We develop and estimate a model of the decision to write D&O insurance and the extent of market participation. Our results suggest that there are significant operational and financial differences between firms that supply D&O insurance and those that do not. Several of these differences (specifically, size, diversification, and organizational form) are consistent with the predictions of the managerial discretion hypothesis.     

Capital expenditures,financial constraints,and the use of options

This paper analyzes why gold mining firms use options instead of linear strategies to hedge their gold price risk. Consistent with financial constraints based theories, the largest and least financially constrained firms are the most likely to hedge with insurance strategies (put options), while more constrained firms finance the purchase of puts by selling calls (collars). The most financially constrained firms use strategies that involve selling calls. Firms with large investment programs are also more likely to use insurance rather than linear strategies. Firms’ hedging instrument choices are also correlated with current market conditions, suggesting that managers’ market views partially drive hedging instrument choices.     

The Risk‐Sharing Implications of Disaster Insurance Funds

We study the risk‐sharing implications that arise from introducing a disaster insurance fund to the cat insurance market. Such a form of intervention can increase efficiency in the private market, and our design of disaster insurance suggests a prominent role of catastrophe reinsurance. The model predicts buyers will increase their demand in the private market, and the seller will lower prices to such an extent that their revenues decrease upon introduction of disaster insurance. We test two predictions in the context of the Terrorism Risk Insurance Act (TRIA). It is already known that the introduction of TRIA led to negative abnormal returns in the insurance industry. In addition, we show this negative effect is stronger for larger and for low‐risk‐averse firms—two results that are consistent with our model. The seller’s risk aversion plays an important role in quantifying such feedback effects, and we point toward possible distortions in which a firm may even be overhedged upon introduction of disaster insurance.     

Risk Mutualization and Competition in Insurance Markets

The aim of this paper is to analyze the impact of mutual firms on competition in the insurance market. We distinguish two actors in this market: mutual firms, which belong to their pooled members, and traditional companies, which belong to their shareholders. Our approach differs from the literature by one crucial assumption: the expected utility of the consumers depends on the size of their insurance firm, which generates network externalities in this market. Thus, the choice of a contract results in a trade-off between the premium level and the probability of that premium being ex-post adjusted. The optimal contract offered by a mutual firm involves a systematic ex-post adjustment (negative or positive), while the contracts a company offers imply a fixed premium that is possibly negatively adjusted at the end of the contractual period. In an oligopoly game, we show that three types of configurations are possible at equilibrium: either one mutual firm or insurance company is active, or a mixed structure emerges in which two or more companies share the market with or without a mutual firm.     

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.
