Book Description
This dissertation consists of two topics. Chapter 1 explores the relationship between U.S. Property-Casualty (P/C) insurers' underwriting risk, investment risk, and leverage risk, using data from 1998 to 2013. I test the trade-off hypothesis using a simultaneous equation model framework with partial adjustment effects. The three equations model intend to examine the interrelations between insurers' leverage and two measures of firm risks: underwriting risk and investment risk. The empirical evidence, various to different sample periods and model specifications, suggests there is no significant relationship existing between insurers' underwriting risk and investment risk. But these two types of risks are both significantly and negatively related to the leverage ratio. The overall results imply that insurers tend to tradeoff leverage risk and underwriting risk/investment risk, but it appears that they have not taken an integrated approach between the total level of underwriting risk and investment risk yet. The second part of this dissertation empirically investigates the impact of credit risk on insurers' reinsurance demand, using data on the U.S. P/C insurance industry from 2000 to 2014. I mainly explore how insurers' credit rating status and downgrade risk affects their reinsurance demand. Using a two-stage least square (2SLS) regression model, I find that low-rated insurers are associated with a higher utilization of reinsurance. In addition, insurers that are downgraded in the previous year tend to have a higher reinsurance demand than the others. Results also show that downgraded group-affiliated insurers tend to significantly increase their internal reinsurance demand from the group-affiliated members while decreasing the purchase of external reinsurance significantly. In general, I find that insurers' reinsurance demand is affected by their credit rating and downgrade risk.

Book Description
The Economics of Property-Casualty Insurance presents new research and findings on key aspects of the economics of the property-casualty insurance industry. The volume explores the industrial organization, regulation, financing, and taxation of this business. The first paper, on external financing and insurance cycles, contains a wealth of information on trends and patterns in the industry's financial structure. The last essay, which compares performance of stock and mutual insurance companies, takes a fresh look at the way a company's organizational structure affects its responses to different economic situations. Two papers focus on rate regulation in the auto insurance industry, and provide broad overviews of the structure and economics of the insurance industry as a whole. Also addressed are the system of regulating insurance companies in the United States, who insures the insurers, and the effects of tax law changes in the 1980s on the prices of insurance policies.

Book Description
This dissertation consists of two topics. Chapter 1 examines the relationship between contingent commission use and underwriting performance as well as underwriting risk using data from 2005 to 2016. Top brokers were banned from receiving contingent commissions following the inquiry in 2004 led by Eliot Spitzer, former New York Attorney-General. But the ban raised concerns about whether it created a level playing field across the industry, as smaller brokers continued taking them. In addition, despite the possible conflicts of interest, contingent commissions have also been recognized as a way to better align agent and insurer incentives. Regulators agreed to relax the terms for the leading brokers in 2010, resulting in a less onerous compliance regime for contingent commission use. It is important to study the effectiveness of contingent commission use on improving underwriting performance. This study finds strong evidence supporting the hypothesis that contingent commissions' usage is associated with better underwriting performance as well as lower underwriting risk. This study also finds a curvilinear relationship between underwriting performance and the level of contingent commission use. Chapter 2 investigates the impact of executive overconfidence on capital structure decisions and reinsurance purchases using a sample of 37 publicly-traded property-liability insurance groups for the period 2002 to 2016. This study finds that insurance firms with overconfident executives have significantly higher leverage ratios than those without overconfident executives. This study also finds evidence that insurance firms with overconfident executives cede more reinsurance, and this evidence is stronger for insurers with more limited business capacity than those with ample business capacity. The results of this study also indicate that overconfident executives prefer internal reinsurance to external reinsurance. This research provides evidence that personality traits of executive impact capital structure decisions and reinsurance purchases for insurance firms, which should be of interest to policyholders and regulators.

Book Description
This dissertation includes two chapters. In Chapter 1, "Information Risk and the Cost of Equity Capital Revisited: Evidence from the U.S. Property-Casualty Insurance Industry", I revisit the relationship between information risk and the cost of equity capital in the U.S. property-casualty (P-C) insurance industry. Eckles, Halek and Zhang (2014) find that information risk has no effect on the cost of equity using a sample of U.S. P-C insurers. Following their approach, we decompose information risk into innate and discretionary components. I find that innate information risk affects the cost of equity capital through two opposing channels. On the one hand, innate information risk directly increases an insurer's cost of equity capital by increasing investors' assessment of the riskiness of the insurer's future cash flows. On the other hand, innate information risk indirectly decreases the insurer's cost of equity capital by changing its production so that the assessed riskiness of the firm's future cash flows are reduced. This (negative) indirect effect depends on factors that influence the insurer's underwriting decisions. My empirical results provide supporting evidence for a significant, positive direct effect of innate information risk, while the magnitude of the (negative) indirect effect increases with the insurer's proportion of long-tail business and decreases with its affiliated reinsurance usage. As to the impact of discretionary information risk, my results are mixed. I also find that, on average, the overall effect of information risk on the cost of equity capital for property-casualty insurers is significant and negative. In Chapter 2, "Coordination of Capital, Earnings, and Taxes in the U.S. Property-Casualty Insurance Industry", I investigate how property-casualty (P-C) insurers manage discretionary tools to achieve regulatory capital, earnings, and tax planning goals. I examine one accrual tool, loss reserve errors, together with two real transaction tools: realized capital gains (losses) from investment sales, and capital contributions. I find that when P-C insurers have lower pre-managed capital levels, managers will report income-increasing loss reserve errors, recognize more realized capital gains and receive more capital contributions. When P-C insurers have lower pre-managed earnings, managers will report income-increasing loss reserve errors. When P-C insurers have higher marginal tax rates, managers will report income-decreasing loss reserve errors and recognize more realized capital losses. Moreover, I analyze the effect of ownership structures on the degree of managerial discretion for various reporting goals. My analysis includes three different types of ownership structures: public, private stock and mutual firms. I find that, through the use of capital contributions, public firms are more aggressive in capital management, while mutual firms are less aggressive in capital management than private stock firms. In terms of using the other two tools, compared to private stock firms, public firms do not manage capital less aggressively; they do not manage earnings more aggressively; they do not manage taxes less aggressively. Compared to private stock firms, mutual firms are less aggressive in capital management; they are more aggressive in earnings management; they are less aggressive in tax management.

Book Description
The first part of the dissertation investigates cost experience in the US life and health insurance industry over the period 1998-2012. We generally test the difference in expenses among different distribution systems, which mainly consists of independent agency, broker, career agency, exclusive agency, and direct writing. We check to see if cost, revenue and profit efficiency differences are associated with different distribution methods. Cost, revenue, and profit efficiencies are estimated by Data Envelopment Analysis. Unlike the results in the property and liability insurance industry, the cost difference is insignificant among distribution systems. Results on cost efficiency and revenue efficiency support the market imperfection hypothesis, which says that the market imperfections such as entry barriers, price regulation, or search costs cause the coexistence of different distribution systems. The second part of the dissertation examines the relationship between mergers and acquisitions (M&As), and underwriting cycles in the P-L insurance industry. In a soft market, capital is relatively high. This leads to an increase in the number of M&A transactions and the probability that managers conduct non-value-increasing M&As. We test this proposition by analyzing the associations between volumes of M&A deals, and returns associated with M&As and underwriting cycle. The results show that the numbers of M&As are negatively related with the premium rate changes and positively related with changes in the combined ratio. We also find that the cumulative abnormal returns around the announcement date of M&As are smaller for the shareholders of insurer acquirers in a soft market. Even more, we find that the market reaction of M&As is less sensitive to agency problems in a hard market than in a soft market.

Book Description
This paper presents an empirical analysis of the economic performance of the U.S. property-casualty insurance industry, using estimations across 18 lines of insurance for the years 1984-1993. It adopts an industrial organization approach, focusing on loss ratios and combined ratios as measures of pricing performance. The line's seller concentration ratio and share of direct writers in the line are both found to be significant determinants of performance. The results are consistent with shortcomings in competition in some insurance lines.

Book Description
Is it possible that the insurance and reinsurance industries cannot handle a major catastrophe? Ten years ago, the notion that the overall cost of a single catastrophic event might exceed $10 billion was unthinkable. With ever increasing property-casualty risks and unabated growth in hazard-prone areas, insurers and reinsurers now envision the possibility of disaster losses of $50 to $100 billion in the United States. Against this backdrop, the capitalization of the insurance and reinsurance industries has become a crucial concern. While it remains unlikely that a single event might entirely bankrupt these industries, a big catastrophe could place firms under severe stress, jeopardizing both policy holders and investors and causing profound ripple effects throughout the U.S. economy. The Financing of Catastrophe Risk assembles an impressive roster of experts from academia and industry to explore the disturbing yet realistic assumption that a large catastrophic event is inevitable. The essays offer tangible means of both reassessing and raising the level of preparedness throughout the insurance and reinsurance industries.

Book Description
This dissertation consists of four essays on insurance economies. It aims to answer questions in the fields of insurance transactions (Essays I and IV) as well as insurance operations and strategies (Essays II and III). These questions are relevant both to the insurance academic community and to the insurance industry. The methodologies explored in the dissertation are mainly empirical economics including multivariate regressions, data envelopment analyses, among others. The first essay, "Between-group adverse selection: Evidence from group critical illness insurance", demonstrates the presence of adverse selection in the group insurance market even if individual choices are not allowed. It shows that group insurance alone is not effective enough to eliminate adverse selection, i.e., between-group adverse selection exists, which, however, disappears over time if the group renews with the same insurer for a certain period. The results thus indicate that experience rating and underwriting based on information that insurers learn over time are important in addressing adverse selection. The second essay, "The structure of the global reinsurance market: An analysis of efficiency, scale, and scope", uses a multidimensional data envelopment analysis to study economies of scale, economies of scope, and cost efficiency in the reinsurance industry. Reinsurers with total assets less than USD 2.9 billion exhibit scale economies, while those with assets greater than USD 15.5 billion do not. Large reinsurers are characterized by high cost efficiency. Small reinsurers exhibit superior efficiency when they are specialized. The third essay, "Internationalization and performance: The role of industry context and cost efficiency", analyzes the impact of globalization strategies (inter-regional internationalization) on insurers' performance and show that the impact is different for life and nonlife insurers. It introduces the cost efficiency to expl.
