The Internet provides an infrastructure that makes the steadily increasing amount of information accessible efficiently, quickly, and inexpensively. Closely connec ted with this opportunity is the danger that the available information will over charge the individual information seeker's capability to process the information and to judge its quality. In this situation, information intermediaries can take upon the role of an expert and a guarantor of quality similar to intermediaries in markets for physical goods or finances. Thus, information intermediaries can be a trust worthy, information processing third party, mediating between information seekers and information sources. The current technological development has created information technologies that are capable to efficiently process large amounts of information. However, the pro vision of intermediation services necessitates a thorough examination of the basic principles underlying the economics of information intermediaries as well as a sound foundation on information technologies. The present work by Frank Rose addresses the fundamental question concerning the economics of information intermediaries by means of an abstract model. The model focuses on services that concentrate on the search and mediation of information, and identifies the essential influencing factors of the intermediary's environment. The model is then employed to investigate the impact of environmental conditions on the information intermediary on the one hand, and the optimal strategy of the information intermediary as a reaction to environmental conditions on the other hand.

Insurance intermediaries can help consumers to economize on information and transaction costs in insurance markets. This book analyzes conduct and performance in the market for insurance information services by applying search theoretical and industrial organization approaches. Based on a sample of 927 insurance intermediaries, coverage empirically studies the factors that affect the quality of the information services provided by them.

This paper explores a class of firms: the intermediaries of personal information. In the economics of personal information, scarcity is no longer the only, and foremost, determinant of value. The most important determinant of value becomes connection. Adapting what Gervais claims to be the first law of an information-flooded cloud-modelled economy, value is not derived from scarcity but rather from the fact that those who value it most will find it. Personal information is the raw material to create connections. Intermediaries collect personal information in exchange for goods or services, regardless of whether they actually need that information to perform their main activity, and use this information to connect other goods and services with the users who value them most, e.g. via personalisation or targeted advertising. Many firms in many different sectors are, or could become, intermediaries of personal information, from Google to supermarkets, from telecom operators to insurance companies. The descriptive analysis of this industry has consequences in terms of business model and regulatory approach. As for the former, it is worth exploring the conditions for which a firm could profitably become an intermediary of personal information and thereby exploit untapped resources for revenue generation. As for the latter, an imperfect understanding of the economics of personal information creates the risk for misaligned norms, and therefore for an uneven competition.

The Economics of Information Technology is a concise and accessible review of some of the important economic factors affecting information technology industries. These industries are characterized by high fixed costs and low marginal costs of production, large switching costs for users, and strong network effects. These factors combine to produce some unique behavior. The book consists of two parts. In the first part, Professor Varian outlines the basic economics of these industries. In the second part, Professors Farrell and Shapiro describe the impact of these factors on competition policy. The clarity of the analysis and exposition makes this an ideal introduction for undergraduate and graduate students in economics, business strategy, law and related areas.

This SPR Departmental Paper will provide policymakers with a framework for studying changes to national data policy frameworks.

In this revised second edition, An Introduction to the Economics of Information covers the consequences for the character and efficiency of the interaction between individuals and organizations when one party has more or better information on some aspect of the relationship. This is the condition of asymmetric information, under which the information gap will be exploited if, by doing so, the better-informed party can achieve some advantage. The book is written for a one-semester course for advanced undergraduates taking specialized course options, and for first-year postgraduate students of economics or business. After an introduction to the subject and the presentation of a benchmark model in which both parties share the same information throughout the relationship, chapters are devoted to the three main asymmetric information topics of Moral Hazard, Adverse Selection, and Signalling. The wide range of economic situations where the conclusions are applied includes such areas as finance, regulation, insurance, labour economics, health economics, and even politics. Each chapter presents the basic theory before moving on to applications and advanced topics. The problems are presented in the same framework throughout to allow easy comparison of the different results. This new edition incorporates extended exercises to test the student's understanding of the material, and to develop the tools and skills provided by the main text to solve other, original problems.
