The paper analyzes the effects of informational asymmetries on the market structure of the banking industry in a multi-period model of spatial competition. All lenders face uncertainty with regard to borrowers’ creditworthiness, but, in the process of lending, incumbent banks gather proprietary information about their clients, acquiring an advantage over potential entrants. These informational asymmetries are an important determinant of the industry structure and may represent a barrier to entry for new banks. The paper shows that, in contrast with traditional models of horizontal differentiation, the steady-state equilibrium is characterized by a finite number of banks even in the absence of fixed costs.

From the traditional craft hiring hall to the Web site Monster.com, a multitude of institutions exist to facilitate the matching of workers with firms. The diversity of such Labor Market Intermediaries (LMIs) encompasses criminal records providers, public employment offices, labor unions, temporary help agencies, and centralized medical residency matches. Studies of Labor Market Intermediation analyzes how these third-party actors intercede where workers and firms meet, thereby aiding, impeding, and, in some cases, exploiting the matching process. By building a conceptual foundation for analyzing the roles that these understudied economic actors serve in the labor market, this volume develops both a qualitative and quantitative sense of their significance to market operation and worker welfare. Cross-national in scope, Studies of Labor Market Intermediation is distinctive in coalescing research on a set of market institutions that are typically treated as isolated entities, thus setting a research agenda for analyzing the changing shape of employment in an era of rapid globalization and technological change.

This book shows, from start to finish, how microeconomics can and should be used in the analysis of public policy problems. It is an exciting new way to learn microeconomics, motivated by its application to important, real-world issues. Lee Friedman's modern replacement for his influential 1984 work not only brings the issues addressed into the present but develops all intermediate microeconomic theory to make this book accessible to a much wider audience. Friedman offers the microeconomic tools necessary to understand policy analysis of a wide range of matters of public concern--including the recent California electricity crisis, welfare reform, public school finance, global warming, health insurance, day care, tax policies, college loans, and mass transit pricing. These issues are scrutinized through microeconomic models that identify policy strengths, weaknesses, and ideas for improvements. Each chapter begins with explanations of several fundamental microeconomic principles and then develops models that use and probe them in analyzing specific public policies. The book has two primary and complementary goals. One is to develop skills of economic policy analysis: to design, predict the effects of, and evaluate public policies. The other is to develop a deep understanding of microeconomics as an analytic tool for application--its strengths and extensions into such advanced techniques as general equilibrium models and pricing methods for natural monopolies and its weaknesses, such as behavioral inconsistencies with utility-maximization models and its limits in comparing institutional alternatives. The result is an invaluable professional and academic reference, one whose clear explanation of principles and analytic techniques, and wealth of constructive applications, will ensure it a prominent place not only on the bookshelves but also on the desks of students and professionals alike.

A concise introduction to the theory of contracts, emphasizing basic tools that allow the reader to understand the main theoretical models; revised and updated throughout for this edition.

A novel book that argues that, contrary to received wisdom, some adverse selection in insurance markets is beneficial to society as a whole. It is for all those interested in public policy arguments about insurance and discrimination: policymakers, academics, actuaries, underwriters, disability activists, geneticists and other medical professionals.

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.
