General Equilibrium Foundations of Finance


Book Description

The purpose of General Equilibrium Foundations of Finance is to give a sound economic foundation of finance based on the general equilibrium model with incomplete markets which embodies the famous CAPM as an important special case. This goal is achieved by giving reasonable restrictions on the agents' characteristics that lead to a well determined financial markets model having a unique competitive equilibrium. The innovation of this book is to transfer and to extend the theoretical results on the structure of competitive equilibria into the modern context of incomplete financial markets. General Equilibrium Foundations of Finance should be easily accessible by advanced Ph.D. students as well as by theorists of any subfield of mathematical economics. It should be interesting both for theorists who are looking for possible applications of rigorous theorizing as well as for practitioners who seek for a theoretical foundation of fruitful applications of financial markets' models.




Foundations of Insurance Economics


Book Description

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.







Theory of the Firm in Incomplete Markets


Book Description

Classical general equilibrium theory with incomplete markets assigns utilities to firms just as economists have always assigned utilities to consumers. This theory of the firm is at variance with the Arrow-Debreu model of the firm where decentralized markets function at their best and firms maximizing profits. This book, therefore, considers a model of the firm under time and uncertainty where the objective function of the firm is independent of any exogenously assigned average utility to it. This requires a reformulation of the role capital plays. At variance to classical GEI theory, in this set up, capital as an intermediate good does not enter the utility of the consumers. This allows a convenient formulation of production capacity with non-trivial economic consequences. The book rehabilitates the decentralization property of the Arrow Debreu model to the case where time and uncertainty enters the model in an essential way. The monograph is designed for advanced economics students, PhD students, engineers and researchers interested in production. Some suggestions for further research are mentioned.
