One of the main problems in current economic theory is to write contracts which are Pareto optimal, incentive compatible, and also implementable as a perfect Bayesian equilibrium of a dynamic, noncooperative game. The question arises whether it is possible to provide Walrasian type or cooperative equilibrium concepts which have these properties. This volume contains original contributions on noncooperative and cooperative equilibrium notions in economies with differential information and provides answers to the above questions. Moreover, issues of stability, learning and continuity of alternative equilibria are also examined.

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.

The second in a series of six volumes containing a selection of Joseph Stiglitz's most important and widely cited work. Volume I set out the basic concepts underlying the economics of information. Volume II extends these concepts and applies them to a number of different settings in labour, capital, and product markets

This paper analyzes the origins, implications, and solutions for the Asian financial crisis. From the perspective of a member of the Executive Board of the IMF, as Asian problems were building, the IMF overlooked weaknesses in bank and corporate balance sheets in much of Asia: the IMF was unaware of the extraordinary leverage of Korean companies, which in some cases reached a ratio of 600/1 debt to equity. The IMF did not focus on the weak accounting and disclosure practices of banks and nonbanks or generous rollovers of banks to their key clients.

In the late 1990s, Korea, Thailand, Indonesia and Malaysia experienced a series of major financial crises evinced by widespread bank insolvencies and currency depreciations, as well as sharp declines in gross domestic production. This sudden disruption of the Asian economic `miracle' astounded many observers around the world, raised questions about the stability of the international financial system and caused widespread fear that this financial crisis would spread to other countries. What has been called the Asian crisis followed a prolonged slump in Japan dating from the early 1980s and came after the Mexican currency crisis in the mid-1990s. Thus, the Asian crisis became a major policy concern at the International Monetary Fund as well as among developed countries whose cooperation in dealing with such financial crises is necessary to maintain the stability and efficiency of global financial markets. This book collects the papers and discussions delivered at an October 1998 Conference co-sponsored by the Federal Reserve Bank of Chicago and the International Monetary Fund to examine the causes, implications and possible solutions to the crises. The conference participants included a broad range of academic, industry, and regulatory experts representing more than thirty countries. Topics discussed included the origin of the individual crises; early warning indicators; the role played by the global financial sector in this crisis; how, given an international safety net, potential risks of moral hazard might contribute to further crises; the lessons for the international financial system to be drawn from the Asian crisis; and what the role of the International Monetary Fund might be in future rescue operations. Because the discussions of these topics include a wide diversity of critical views and opinions, the book offers a particularly rich presentation of current and evolving thinking on the causes and preventions of international banking and monetary crises. The book promises to be one of the timeliest as well as one of the most complete treatments of the Asian financial crisis and its implications for future policymaking.

Many of the assumptions that underpin mainstream macroeconomic models have been challenged as a result of the traumatic events of the recent financial crisis. Thus, until recently, it was widely agreed that although the stock of money had a role to play, in practice it could be ignored as long as we used short-term nominal interest rates as the instrument of policy because money and other credit markets would clear at the given policy rate. However, very early on in the financial crisis interest rates effectively hit zero percent and so central banks had to resort to a wholly new set of largely untested instruments to restore order, including quantitative easing and the purchase of toxic financial assets. This book brings together contributions from economists working in academia, financial markets and central banks to assess the effectiveness of these policy instruments and explore what lessons have so far been learned.

Optimal tax design attempts to resolve a well-known trade-off: namely, that high taxes are bad insofar as they discourage people from working, but good to the degree that, by redistributing wealth, they help insure people against productivity shocks. Until recently, however, economic research on this question either ignored people's uncertainty about their future productivities or imposed strong and unrealistic functional form restrictions on taxes. In response to these problems, the new dynamic public finance was developed to study the design of optimal taxes given only minimal restrictions on the set of possible tax instruments, and on the nature of shocks affecting people in the economy. In this book, Narayana Kocherlakota surveys and discusses this exciting new approach to public finance. An important book for advanced PhD courses in public finance and macroeconomics, The New Dynamic Public Finance provides a formal connection between the problem of dynamic optimal taxation and dynamic principal-agent contracting theory. This connection means that the properties of solutions to principal-agent problems can be used to determine the properties of optimal tax systems. The book shows that such optimal tax systems necessarily involve asset income taxes, which may depend in sophisticated ways on current and past labor incomes. It also addresses the implications of this new approach for qualitative properties of optimal monetary policy, optimal government debt policy, and optimal bequest taxes. In addition, the book describes computational methods for approximate calculation of optimal taxes, and discusses possible paths for future research.
