Insurance Economics brings together the economic analysis of decision making under risk, risk management and demand for insurance among individuals and corporations, objectives pursued and management tools used by insurance companies, the regulation of insurance, and the division of labor between private and social insurance. Appropriate both for advanced undergraduate and graduate students of economics, management, and finance, this text provides the background required to understand current research. Predictions derived from theoretical arguments are not merely stated, but also related to empirical evidence. Throughout the book, conclusions summarize key results, helping readers to check their knowledge and comprehension. Issues discussed include paradoxes in decision making under risk and attempts at their resolution, moral hazard and adverse selection including the possibility of a “death spiral”, and future challenges to both private and social insurance such as globalization and the availability of genetic information. This second edition has been extensively revised. Most importantly, substantial content has been added to represent the evolution of risk-related research. A new chapter, Insurance Demand II: Nontraditional Approaches, provides a timely addition in view of recent developments in risk theory and insurance. Previous discussions of Enterprise Risk Management, long-term care insurance, adverse selection, and moral hazard have all been updated. In an effort to expand the global reach of the text, evidence and research from the U. S. and China have also been added.

Die nachhaltige L sung von Problemen der Energieversorgung geh rt zu den zentralen Herausforderungen moderner Zivilisationen. Aus konomischer Sicht greifen alle Antworten zu kurz, die nicht explizit das interessengeleitete Handeln der wesentlichen Akteure ber cksichtigen. Deshalb behandelt dieses Buch die nachfrage- und angebotsseitigen Gesetzm igkeiten der verschiedenen Energiem rkte, und zwar unter R ckgriff auf industrie- und institutionen konomische Theoriebausteine. Die technisch-naturwissenschaftlichen Bedingungen von Gewinnung, Wandlung, Transport, Verteilung und Nutzung von Energietr gern werden dabei stets ber cksichtigt. Ein wichtiges Thema f r die Praktiker sind die von der Liberalisierung der leitungsgebundenen Energiem rkte ausgehenden Impulse. Wo immer m glich werden die theoretisch hergeleiteten Voraussagen durch die Konfrontation mit statistischer Evidenz auf ihre Praxisrelevanz gepr ft.

This book provides an introduction to energy economics. It shows how to apply general economic theory as well as empirical and advanced econometric methods to explain the drivers of energy markets and their development. Readers learn about the specific properties of energy markets as well as the physical, technological, environmental, and geopolitical particularities of energy sources and products. The book covers all types of energy markets, ranging from liquid fuels, gaseous fuels, and solid fuels to electricity. It also addresses emission allowances, energy efficiency, and nuclear risks. The authors discuss the engineering properties of energy technologies including renewables, the economics of natural resources and environmental protection, market liberalization, and energy trade as well as the experience of the German energy transformation. This book will serve students as a textbook and practitioners as a reference for their understanding of energy markets and their development.

Health Economics presents a systematic treatment of the economics of health behavior and health care delivery. Appropriate both for advanced undergraduate and graduate students of economics, this text provides the background required to understand current research, presenting theoretical models as well as empirical evidence and summarizing key results. Without neglecting ethical concerns, modern microeconomic theory is applied to formulate theoretical implications and predictions. Issues discussed include the economic valuation of life and health, moral hazard in health care utilization, supplier-induced demand, the search for remuneration systems with favorable incentives, risk selection in health insurance markets, and technological change in medicine.

Dieses Buch macht den Leser mit den zentralen Fragestellungen und dem analytischen Werkzeug der Gesundheitsökonomik vertraut. Erörtert werden u.a. die Ausgabendynamik im Gesundheitswesen, der Umgang mit der Gesundheit, die Rolle des Arztes und sein Verhalten, Ineffizienzen in Krankenhäusern und die Anreize zur Risikoselektion im Krankenkassenwettbewerb. Diese Themen werden stringent mit mikroökonomischen Methoden analysiert, ethische Gesichtspunkte jedoch auch berücksichtigt. Diskutiert werden zudem Ergebnisse empirischer Forschung und aktuelle Reformvorschläge wie die Bürgerversicherung und die Einführung von Pauschalprämien in der gesetzlichen Krankenversicherung. Die 6. Auflage wurde vollständig überabeitet, um wichtige Neuerungen ergänzt und aktualisiert.

Confronted with the continuing cost expansion in the health care sector, policy makers face a dilemma: limiting moral hazard in medical care requires that consumers participate in the cost, yet copayment is strongly resisted by today's socially insured. Thus, the experiences of three private German health insurers will be of interest to physicians, social scientists, and policy makers. Insurer A writes conventional plans with deductibles and coinsurance; B pays back three-monthly premiums as a fixed rebate for no claims; while C runs an experience-rated bonus system starting with a rebate of three-monthly premiums for the first year without a claim, reaching a maximum of five after three years. While both rebates and bonuses are quite popular among insureds, this study shows that bonus options are particularly effective in limiting the demand for ambulatory and even hospital care. But what about adverse effects on health caused by the desire to save one's bonus? On this issue, there is some surprising evidence.

Appropriete both for advanced undergraduate and graduate students of economics, management, and finance, this text provides the background required to understand current research. Predictions derived from theoretical argument are not only stated but confronted with empirical evidence. Throughout the book, conclusions summarize results, helping readers to check their knowledge and understanding. Issues discussed include paradoxa in decision making under risk, selection of favorable risks by insurers, the possibility of a "death spiral" in insurance markets, and future challenges such as re-regulation in the wake of the 2007-09 financial crisis and the increasing availability of generic information.

Die nachhaltige Lösung von Problemen der Energieversorgung gehört zu den zentralen Herausforderungen moderner Zivilisationen. Aus ökonomischer Sicht greifen alle Antworten zu kurz, die nicht explizit das interessengeleitete Handeln der wesentlichen Akteure berücksichtigen. Deshalb behandelt dieses Buch die nachfrage- und angebotsseitigen Gesetzmäßigkeiten der verschiedenen Energiemärkte, und zwar unter Rückgriff auf industrie- und institutionenökonomische Theoriebausteine. Die technisch-naturwissenschaftlichen Bedingungen von Gewinnung, Wandlung, Transport, Verteilung und Nutzung von Energieträgern werden dabei stets berücksichtigt. Ein wichtiges Thema für die Praktiker sind die von der Liberalisierung der leitungsgebundenen Energiemärkte ausgehenden Impulse. Wo immer möglich werden die theoretisch hergeleiteten Voraussagen durch die Konfrontation mit statistischer Evidenz auf ihre Praxisrelevanz geprüft.

Das Buch macht den Leser mit den zentralen Fragestellungen und dem analytischen Werkzeug der Versicherungsökonomie vertraut. Es führt Beiträge zur Nachfrage nach Versicherung, zum Angebot an Versicherung und der Versicherungsregulierung sowie zur Sozialversicherung in einer vereinheitlichten Darstellung zusammen, die bisher nur verstreut in Zeitschriften und Sammelbänden verfügbar waren. Es werden empirisch überprüfbare Voraussagen der Theorie abgleitet und den Ergebnissen internationaler empirischer Forschung gegenübergestellt. Ausformulierte Folgerungen fassen den Stoff zusammen und erleichtern die Kontrolle des Wissensstands.

Dieses Lehrbuch vermittelt in kompakter Form einen Überblick über die Theorie des Internationalen Handels. Die mikroökonomische Analyse der internationalen Wirtschaftsbeziehungen wird oft als eine Anwendung der Allgemeinen Gleichgewichtstheorie dargestellt und wirkt entsprechend trocken und abstrakt. Demgegenüber wird hier die Theorie als Werkzeug zur Erklärung und Voraussage von beobachtbaren Phänomenen verstanden. Deshalb schließt jedes Kapital mit einer Diskussion von empirischen Überprüfungen und ihren Ergebnissen ab. Das Buch enthält zu jedem Kapital Übungsaufgaben und geht insbesondere auf die Außenwirtschaftdaten Deutschlands, Österreichs und der Schweiz ein.
