Book Description
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.

Book Description
"The report assesses the initiatives for information exchange among firms and their consequences for welfare with a view towards the design of competition policy in this domain. To this end the report surveys critically the academic literature on static and dynamic models of competition in their relation to information exchange and examines the main antitrust legislation and cases in Europe and the US."--Page i.

Book Description
A review of the theoretical research on unlawful collusion, focusing on the impact and optimal design of competition law and enforcement. Collusion occurs when firms in a market coordinate their behavior for the purpose of producing a supracompetitive outcome. The literature on the theory of collusion is deep and broad but most of that work does not take account of the possible illegality of collusion. Recently, there has been a growing body of research that explicitly focuses on collusion that runs afoul of competition law and thereby makes firms potentially liable for penalties. This book, by an expert on the subject, reviews the theoretical research on unlawful collusion, with a focus on two issues: the impact of competition law and enforcement on whether, how long, and how much firms collude; and the optimal design of competition law and enforcement. The book begins by discussing general issues that arise when models of collusion take into account competition law and enforcement. It goes on to consider game-theoretic models that encompass the probability of detection and penalties incurred when convicted, and examines how these policy instruments affect the frequency of cartels, cartel duration, cartel participation, and collusive prices. The book then considers the design of competition law and enforcement, examining such topics as the formula for penalties and leniency programs. The book concludes with suggested future lines of inquiry into illegal collusion.

Book Description
A dynamic and competitive environment, underpinned by competition law policy, is an essential characteristic of successful market economies. To satisfy the growing demand for information on current approaches and practices in competition law policy, the project "Framework for the Design and Implementation of Competition Law-Policy" was initiated by the World Bank, with participation by OECD. This ensuing volume reflects the main issues that arise in design and implementation of competition law and policy in order to assist countries in developing an approach that suits their own needs and conditions. The views articulated in this publication suggest that the administration and enforcement of competition law policy should assign the greatest importance to fostering economic efficiency and consumer welfare.

Book Description
Antitrust law regulates economic activity but differs in its operation from what is traditionally considered "regulation." Where regulation is often industry-specific and involves the direct setting of prices, product characteristics, or entry, antitrust law focuses more broadly on maintaining certain basic rules of competition. In these lectures Michael Whinston offers an accessible and lucid account of the economics behind antitrust law, looking at some of the most recent developments in antitrust economics and highlighting areas that require further research. He focuses on three areas: price fixing, in which competitors agree to restrict output or raise price; horizontal mergers, in which competitors agree to merge their operations; and exclusionary vertical contracts, in which a competitor seeks to exclude a rival. Antitrust commentators widely regard the prohibition on price fixing as the most settled and economically sound area of antitrust. Whinston's discussion seeks to unsettle this view, suggesting that some fundamental issues in this area are, in fact, not well understood. In his discussion of horizontal mergers, Whinston describes the substantial advances in recent theoretical and empirical work and suggests fruitful directions for further research. The complex area of exclusionary vertical contracts is perhaps the most controversial in antitrust. The influential "Chicago School" cast doubt on arguments that vertical contracts could be profitably used to exclude rivals. Recent theoretical work, to which Whinston has made important contributions, instead shows that such contracts can be profitable tools for exclusion. Whinston's discussion sheds light on the controversy in this area and the nature of those recent theoretical contributions. Sponsored by the Universidad Torcuato Di Tella
