Insurance and financial markets have been radically and deeply changed in the last 20 years. Deregulation, internationalization of insurance and financial institutions, increasing competition, electronic commerce, bancassurance, and the emergence of new risks are among the challenges faced by insurers and other financial firms. These developing trends pose both global and local challenges for financial firms participating in insurance markets. "The Handbook of International Insurance: Between Global Dynamics and Local Contingencies" increases understanding of insurance markets by adopting an international comparative approach. Leading scholars and practitioners worldwide provide detailed information on market trends, regulation, taxation, and economic developments for thirteen specific countries in Europe, the Americas, and Asia. Each country chapter covers key aspects of insurance: life insurance, non-life insurance, and public and private social insurance programs. The book also includes comprehensive chapters on reinsurance, Lloyd’s of London, alternative risk transfer, South and East Asian insurance markets, and European insurance markets. Setting the stage is an overview chapter by the editors focusing on overall conclusions on globalization. A unique source of information on the evolution of insurance markets worldwide, this book provides valuable perspectives for scholars, practitioners, and policy makers.

Major challenges for life insurance companies have been posed by an unprecedented wave of mergers and acquisitions in the insurance industry and the emergence of non-traditional competitors such as banks, mutual fund companies and investment advisory firms. This is the first book to analyze the determinants of firm performance in the life insurance industry by identifying the `best practices' employed by leading insurers to succeed in this dynamic business environment. The book draws upon data from insurer financial statements as well as upon an extensive survey of life insurer management practices and strategic choices in distribution systems, information technology, mergers and acquisitions, human resources and financial strategies. Generic strategies such as cost leadership, customer focus, and product differentiation are analyzed as well as strategic practices specific to the insurance industry. Best practices are identified by measuring the economic efficiency of insurers and by comparing firms across the industry. Both cost and revenue efficiency are measured relative to best practice efficient frontiers consisting of the industry's dominant life insurance firms. Economies of scale and the effects of mergers and acquisitions on efficiency are also analyzed. Financial strategies are examined with specific reference to pricing policy, valuation of assets and liabilities, and the current state of firm-level risk management systems. The benchmarks established are the result of extensive fieldwork that identifies key financial risks and methodologies to both measure and manage them at the firm level. The results discussed in the book indicate that firm performance is significantly correlated with management practices and strategic choices. Thus, life insurers can improve profitability by adopting optimal combinations of strategies. The book contains important new material on the effects of strategic choices in product distributionsystems, information technology, mergers and acquisitions, human resources, and financial risk management policies. In the area of efficiency, the methodology provides a new approach for identifying peer groups of insurers and measuring the performance of individual insurers relative to their peer group. On the topics of risk and pricing, new insights are offered relative to current methodologies and in regard to areas where improvement is clearly warranted. The book concludes with an analysis of the future opportunities and challenges in the life insurance industry facing managers, and the strategic options available to them to cope with these changes.

The First International Conference on Insurance Solvency was held at the Wharton School, University of Pennsylvania from June 18th through June 20th, 1986. The conference was the inaugural event for Wharton's Center for Research on Risk and Insurance. In atten­ dance were thirty-nine representatives from Australia, Canada, France, Germany, Israel, the United Kingdom, and the United States. The papers presented at the Conference are published in two volumes, this book and a companion volume, Classical Insurance Solvency Theory, J. D. Cummins and R. A. Derrig, eds. (Norwell, MA: Kluwer Academic Publishers, 1988). The first volume presented two papers reflecting important advances in actuarial solvency theory. The current volume goes beyond the actuarial approach to encom­ pass papers applying the insights and techniques of financial economics. The papers fall into two groups. The first group con­ sists of papers that adopt an essentially actuarial or statistical ap­ proach to solvency modelling. These papers represent methodology advances over prior efforts at operational modelling of insurance companies. The emphasis is on cash flow analysis and many of the models incorporate investment income, inflation, taxation, and other economic variables. The papers in second group bring financial economics to bear on various aspects of solvency analysis. These papers discuss insurance applications of asset pricing models, capital structure theory, and the economic theory of agency.

Two different applications have been considered, automobile claims from Massachusetts and health expenses from the Netherlands. We have fit 11 different distributions to these data. The distributions are conveniently nested within a single four parameter distribution, the generalized beta of the second type. This relationship facilitates analysis and comparisons. In both cases the GB2 provided the best fit and the Burr 3 is the best three parameter model. In the case of automobile claims, the flexibility of the GB2 provides a statistically siE;nificant improvement in fit over all other models. In the case of Dutch health expenses the improvement of the GB2 relative to several alternatives was not statistically significant. * The author appreciates the research assistance of Mark Bean, Young Yong Kim and Steve White. The data used were provided by Richard Derrig of The Massachusetts Automobile Rating and Accident Prevention Bureau and by Bob Van der Laan and The Silver Cross Foundation for the medical insurance claim data. 2~ REFERENCES Arnold, B.

th This book is published to commemorate the 50 Anniversary of the S.S. Huebner Foundation for Insurance Education. Administered at the Wharton School of the University of Pennsylvania, the Huebner Foundation was established in 1941 to strengthen insurance education at the collegiate level by increasing the number of professors specializing in insurance and enriching the literature in the field. The financial support of leading life insurance companies has enabled the Foundation to provide post-graduate education for prospective insurance teachers and scholars. Through its fellowship program, the Foundation supports students in the Ph.D. program in Risk and Insurance at the Wharton School. The success of the Foundation is measured by the accomplishments of its alumni. Former Huebner Fellows play leading roles in every major area of insurance education. Fellows teach insurance to tens of thousands of undergraduate and MBA students each year and have written hundreds of books and thousands of articles on insurance. Fellows hold leadership positions at the American College, the Life Office Management Association, and the Certified Employee Benefit Specialist Program. The Foundation was created in honor of Dr. Solomon S. Huebner, a pioneer in insurance education. Dr. Huebner taught the first organized course on the economics of insurance ever offered at the collegiate level in 1904. An internationally recognized author and teacher, Dr. Huebner had a profound impact on both insurance education and the insurance industry. He served on the faculty of the Wharton School for more than nearly fifty years.

Over the past two decades, the United States has successfully deregulated prices and restrictions on most previously-regulated industries, including airlines, trucking, railroads, telecommunications, and banking. Only a few industries remain regulated, the largest being the property-liability insurance business. In light of recent sweeping financial modernization legislation in other sectors of the insurance industry, this timely volume examines the basis for continued regulation of rates and forms of the U.S. property-liability insurance market. The book focuses on private passenger automobile insurance—the most important personal line of property-liability coverage, with annual premiums of about $120 billion. The authors analyze five state case studies: California, Massachusetts, and New Jersey—three of the most heavily regulated states—as well as Illinois, which has been deregulated for about 30 years, and South Carolina, which began to deregulate in 1997. The study also includes an econometric analysis based on all fifty states over a 25-year period that gauges the impact of regulation on insurance price levels, price volatility, and the proportion of automobiles insured in residual markets. The authors conclude that regulation does not significantly reduce long-run prices for consumers, and generally limits availability of coverage, reduces the quality and variety of services available in the market, inhibits productivity growth, and increases price volatility. Contributors include Dwight Jaffee (University of California, Berkeley), Thomas Russell (Santa Clara University ), Laureen Regan (Temple University), Sharon Tennyson (Cornell University), Mary Weiss (Temple University), John Worrall (Rutgers University), Stephen D'Arcy (University of Illinois, Urbana-Champaign), Martin Grace (Georgia State University), Robert Klein (Georgia State University), Richard Phillips (Georgia State University), Georges Dionne (University of Montreal), and Richard Butler (Brigham Young University).

The research project leading to this book was initiated in the fall of 1979 when the American Council of Life Insurance (ACLI) contacted Dan McGill, chairman of the Wharton School Insurance Department, about conducting a study on risk classification in life insurance. The ACLI was concerned about legislative and judicial activity in this area and its potential effects on the life insurance industry. A meeting was held at the ACLI offices in Washington, D.C., between several members of the ACLI staff and Dan McGill and David Cummins representing the Wharton School insurance department. An agreement was reached that a study would be conducted at Wharton dealing with issues in risk classification. Although the staff of the ACLI suggested directions the study might take, it was agreed that the design and execution of the study would be solely under the control of the researchers. The researchers also retained unrestricted publication rights in the results of the study. This agreement has been honored by the ACLI during the course of the project.

The Geneva Association and Risk Economics The Geneva Association The Geneva Association (International Association for the Study of Insurance Economics) commenced its activities in June 1973, on the initiative of twenty-two members in eight European countries. It now has fifty-four members in sixteen countries in Europe and in the United States. The members of the association are insurance companies which provide financial support for its activities. The aims and strategy of the Geneva Association were clearly defined in 1971 by the founding committee. They were set forth in the first report to the Assembly of Members in 1974: "To make an original contribution to the progress of insurance by objective studies on the interdependence between economics and insurance." In pursuit of this objective, the Association strives to place insurance problems in the context of the modern economy and to overcome the antagonism between different groups and institutions by showing that they all have a common interest in tackling the problem of risk in a changing world. In consequence, the studies made by the Association had to move away from the subjects familiar to insurance professionals and explore related fields, dealing with opinions and behavior falling outside the profession's vii FOREWORD viii traditional framework of analysis. It is in this direction that the Association's preoccupations have been directed from the beginning, towards areas in which insurance activities come into contact with those of other economic sectors such as government, banking, manufacturing, and households.

The problem of solvency is, in fact, as old as insurance. The history of the industry knows many ways to meet the risks involved with underwriting, such as spreading the risk portfolio (Cato, Senior already applied it), risk selection, reserve funds, reinsurance, etc. Whilst these measures too often proved ineffective, the establish­ ment of legislative control and public supervision ensued. However, not until the last few decades has the solvency issue become an ob­ ject of intensive studies, very much thanks to the progress of related empirical and theoretical knowledge, and in the under­ standing of the concerned complicated processes. The research activities have grown extensively in many countries in recent years. The more the studies advance the more new relevant aspects are detected and a great variety of alternative proposals have come up for discussion. Therefore, it has become necessary to attempt a survey of the whole problem area in order to be able to place the quite numerous pieces of knowledge in their proper context, and also, among other things, to avoid the pitfalls of handling isolated problems omitting vital tie-ins to the environment. Many of the rele­ vant problems and subproblems are still lacking adequate and well tested solutions. Therefore, a survey of the whole problem area can also hopefully serve as guidance for future research efforts.

Property-liability insurance rates for most lines of business are regulated in about one-half of the states. In most cases, this me ans that rates must be filed with the state insurance commissioner and approved prior to use. The remainder of the states have various forms of competitive rating laws. These either require that rates be filed prior to use but need not be approved or that rates need not be filed at all. State rating laws are summarized in Rand Corporation (1985). The predominant form of insurance rate regulation, prior approval, began in the late 1940s following the V. S. Supreme Court decision in United States vs. South-Eastern Underwriters Association, 322 V. S. 533 (1944). This was an anti trust case involving one of four regional associa­ tions of insurance companies, which constituted an insurance cartel. The case struck down an earlier decision, Paul vs. Virginia, 8 Wall 168 (1869), holding that the business of insurance was not interstate commerce and hence that state regulation of insurance did not violate the commerce clause of the V. S. Constitution. Following South-Eastern Underwriters, the Vnited States Congress passed the McCarran-Ferguson Act, which held that continued state regulation and taxation of insurance was in the public interest. The act also held that the federal antitrust laws would not apply to insurance to the extent that the business was adequately regulated by state law. (See V. S. Department of Justice 1977.

The predominant form of insurance rate regulation, prior approval, began in the late 1940s following the V. S. Supreme Court decision in United States vs. South-Eastern Underwriters Association, 322 V. S. 533 (1944). This was an anti trust case involving one of four regional associa­ tions of insurance companies, which constituted an insurance cartel. The case struck down an earlier decision, Paul vs. Virginia, 8 Wall 168 (1869), holding that the business of insurance was not interstate commerce and hence that state regulation of insurance did not violate the commerce clause of the V. S. Constitution. Following South-Eastern Underwriters, the Vnited States Congress passed the McCarran-Ferguson Act, which held that continued state regulation and taxation of insurance was in the public interest. The act also held that the federal antitrust laws would not apply to insurance to the extent that the business was adequately regulated by state law. (See V. S. Department of Justice 1977.
