Book excerpt: The focus of this thesis is on consumer diversity. Incorporating consumer heterogeneity into economic analysis is well-established in industrial organization literature; this aspect is, however, often neglected in microeconomic insurance models. A first new approach lies in analyzing risk interdependencies. When risks are interdependent, an agent's decision to self-protect affects the loss probabilities faced by others. Due to these externalities, economic agents invest too little in prevention relative to the socially efficient level by ignoring marginal external costs or benefits conferred on others. We analyze an insurance market with externalities of loss prevention. It is shown in a model with heterogenous agents and imperfect information that a monopolistic insurer can achieve the social optimum by engaging in premium discrimination. An insurance monopoly reduces not only costs of risk selection, but may also play an important social role in loss prevention. This result can be empirically confirmed. We also deal with the impact of intermediation on insurance market transparency and performance. In a differentiated insurance market under imperfect information, uninformed consumers may become informed about product suitability by consulting an intermediary. We analyze current broker compensation systems: commissions and fees. While insurers' equilibrium profits are equivalent under both systems, social welfare under fees is first-best efficient. Both systems may offer the opportunity to increase profits via collusion. Under a commission system, collusion enables insurers to separate consumers into groups purchasing different contracts. Insurers may then extract additional rents from some consumers. This might explain why intermediaries tend to be compensated by insurers in practice. Finally, we study optimal monopoly pricing given imperfect information and heterogenous policyholders. Die in englischer Sprache verfasste Arbeit ist der mikroökonomischen Analyse von Versicherungsmärkten gewidmet. Zunächst werden einige wichtige theoretische Grundlagen der Versicherungsnachfragetheorie beschrieben. Eine zentrale Erweiterung des Basismodells stellen interdependente Risiken dar. Bestehen Risikointerdependenzen, so sind alle Maßnahmen, die die Schadenshäufigkeit reduzieren, mit positiven externen Effekten verbunden. Es wird gezeigt, dass im Gleichgewicht das realisierte Präventionsniveau unterhalb des optimalen Niveaus angesiedelt ist. Aufgrund der Externalitäten kommt es zu einem Marktversagen und nur ein Monopolversicherer kann eine differenzierte Prämienstruktur herbeiführen, die zum optimalen Präventionsniveau führt. Dieses Ergebnis kollidiert mit dem Ergebnis, dass wettbewerbliche Versicherungsmärkte zu einer höheren Gesamtwohlfahrt führen, es lässt sich jedoch empirisch stützen. Ein weiterer Schwerpunkt der Arbeit liegt auf unvollkommenen Versicherungsmärkten, wobei heterogene Versicherungsnachfrager mit unterschiedlichen Produktpräferenzen und Informationskosten unterstellt werden. In einem solchen Markt erhöhen Versicherungsvermittler die Markttransparenz und damit auch die Gewinne der Versicherer. Im Mittelpunkt steht die Analyse verschiedener Vergütungsformen der Vermittler. Ein Vergütungssystem auf Basis von Beratungshonoraren ist einem Provisionssystem aus wohlfahrtsökonomischer Perspektive vorzuziehen. Aus Sicht der Versicherer kehrt sich dieses Ergebnis allerdings um, sobald es zur Kollusion zwischen Versicherern und Vermittlern kommt. Der letzte Schwerpunkt liegt in der Analyse einer optimalen Preispolitik eines Versicherungsmonopolisten bei heterogenen Nachfragern, die sich durch ihre Risikopräferenzen und damit ihre individuelle Zahlungsbereitschaft für Versicherungen unterscheiden.

Available in PDF, EPUB and Kindle. Book excerpt: Economic and financial research on insurance markets has undergone dramatic growth since its infancy in the early 1960s. Our main objective in compiling this volume was to achieve a wider dissemination of key papers in this literature. Their significance is highlighted in the introduction, which surveys major areas in insurance economics. While it was not possible to provide comprehensive coverage of insurance economics in this book, these readings provide an essential foundation to those who desire to conduct research and teach in the field. In particular, we hope that this compilation and our introduction will be useful to graduate students and to researchers in economics, finance, and insurance. Our criteria for selecting articles included significance, representativeness, pedagogical value, and our desire to include theoretical and empirical work. While the focus of the applied papers is on property-liability insurance, they illustrate issues, concepts, and methods that are applicable in many areas of insurance. The S. S. Huebner Foundation for Insurance Education at the University of Pennsylvania's Wharton School made this book possible by financing publication costs. We are grateful for this assistance and to J. David Cummins, Executive Director of the Foundation, for his efforts and helpful advice on the contents. We also wish to thank all of the authors and editors who provided permission to reprint articles and our respective institutions for technical and financial support.

Available in PDF, EPUB and Kindle. Book excerpt: This paper questions how heterogeneity of beliefs about the probability of loss affects equilibrium insurance contracts, firm behavior, and welfare focusing especially on the effect of optimism when a monotonicity property, which is a major assumption of prior work, is violated. This paper shows that optimistic individuals could result in insurance driving out individuals who exert effort, if the fraction of such optimistic individuals is significantly large. In addition, this paper shows that optimism could have negative effects on profits of the firm even though both parties realize the asymmetry in beliefs. These results are not only consistent with empirical evidence from several insurance markets on correlation of risk and coverage, but also simply align themselves with empirical evidence on the tendencies of people to be unrealistically optimistic.

Available in PDF, EPUB and Kindle. Book excerpt: In the 1970's, the research agenda in insurance was dominated by optimal insurance coverage, security design, and equilibrium under conditions of imperfect information. The 1980's saw a growth of theoretical developments including non-expected utility, price volatility, retention capacity, the pricing and design of insurance contracts in the presence of multiple risks, and the liability insurance crisis. The empirical study of information problems, financial derivatives, and large losses due to catastrophic events dominated the research agenda in the 1990's. The Handbook of Insurance provides a single reference source on insurance for professors, researchers, graduate students, regulators, consultants, and practitioners, that reviews the research developments in insurance and its related fields that have occurred over the last thirty years. The book starts with the history and foundations of insurance theory and moves on to review asymmetric information, risk management and insurance pricing, and the industrial organization of insurance markets. The book ends with life insurance, pensions, and economic security. Each chapter has been written by a leading authority in insurance, all contributions have been peer reviewed, and each chapter can be read independently of the others.

Available in PDF, EPUB and Kindle. Book excerpt: Addressing the challenge of covering heath care expenses—while minimizing economic risks. Moral hazard—the tendency to change behavior when the cost of that behavior will be borne by others—is a particularly tricky question when considering health care. Kenneth J. Arrow’s seminal 1963 paper on this topic (included in this volume) was one of the first to explore the implication of moral hazard for health care, and Amy Finkelstein—recognized as one of the world’s foremost experts on the topic—here examines this issue in the context of contemporary American health care policy. Drawing on research from both the original RAND Health Insurance Experiment and her own research, including a 2008 Health Insurance Experiment in Oregon, Finkelstein presents compelling evidence that health insurance does indeed affect medical spending and encourages policy solutions that acknowledge and account for this. The volume also features commentaries and insights from other renowned economists, including an introduction by Joseph P. Newhouse that provides context for the discussion, a commentary from Jonathan Gruber that considers provider-side moral hazard, and reflections from Joseph E. Stiglitz and Kenneth J. Arrow. “Reads like a fireside chat among a group of distinguished, articulate health economists.” —Choice
Download or read book Risk Information and Insurance written by Henri Loubergé and published by Springer Science & Business Media. This book was released on 1990-01-31 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Orio Giarini The "Geneva Association" (International Association for the Study of Risk and Insurance Economics) was founded in 1973. The main goal was to stimulate and organize objective research in the field of risk, uncertainty, and insurance, in a world in which such issues were clearly becoming of greater and greater relevance for all economic actors. This was a pioneer ing effort, especially as economic theory and the teaching of economics were still anchored to the key notion of general equilibrium under an assumption of certainty. Thus, we had to start our work almost from scratch. One of the first initiatives was to bring together in Geneva, in June of 1973, all the academics in Europe already involved in risk and insurance economics. We found eight from five different countries who never had met before. This seminar chaired by Raymond Barre, the first president of The Geneva Association, was the first of an annual series that became known as the seminar of "The European Group of Risk and Insurance Economists." Since then more than 100 economists from most European countries as well as participants from two other continents and in particular from the United States have taken part in this seminar.
