Book On Existence and Uniqueness of Equilibrium in a Class of Noisy Rational Expectations Models

Download or read book On Existence and Uniqueness of Equilibrium in a Class of Noisy Rational Expectations Models written by Bradyn M. Breon-Drish and published by . This book was released on 2015 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: I study a general class of noisy rational expectations models that nests the standard Grossman and Stiglitz (1980) and Hellwig (1980) models, but relaxes the usual assumption of joint normality of asset payoffs and supply, and allows for more general signal structures. I provide a constructive proof of existence of equilibrium, characterize the price function, and provide sufficient conditions for uniqueness within the class of equilibria with continuous price functions, which are met by both the Grossman and Stiglitz (1980) model and the Hellwig (1980) model with a continuum of investors. My solution approach does not rely on the typical "conjecture and verify" method, and I exhibit a number of non-normal examples in which asset prices can be characterized explicitly and in closed form. The results presented here open up a broad class of models for applied work. To illustrate the usefulness of generalizing the standard model, I show that in settings with non-normally distributed payoffs, shocks to fundamentals may be amplified purely due to learning effects, price drifts can arise naturally, and the disagreement-return relation depends in a novel way on return skewness.

Book Organization with Incomplete Information

Download or read book Organization with Incomplete Information written by Mukul Majumdar and published by Cambridge University Press. This book was released on 1998-09-13 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: There have been systematic attempts over the last twenty-five years to explore the implications of decision making with incomplete information and to model an 'economic man' as an information-processing organism. These efforts are associated with the work of Roy Radner, who joins other analysts in this collection to offer accessible overviews of the existing literature on topics such as Walrasian equilibrium with incomplete markets, rational expectations equilibrium, learning, Markovian games, dynamic game-theoretic models of organization, and experimental work on mechanism selection. Some essays also take up relatively new themes related to bounded rationality, complexity of decisions, and economic survival. The collection overall introduces models that add to the toolbox of economists, expand the boundaries of economic analysis, and enrich our understanding of the inefficiencies and complexities of organizational design in the presence of uncertainty.

Book Asset Pricing under Asymmetric Information

Download or read book Asset Pricing under Asymmetric Information written by Markus K. Brunnermeier and published by OUP Oxford. This book was released on 2001-01-25 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Asset prices are driven by public news and information that is often dispersed among many market participants. These agents try to infer each other's information by analyzing price processes. In the past two decades, theoretical research in financial economics has significantly advanced our understanding of the informational aspects of price processes. This book provides a detailed and up-to-date survey of this important body of literature. The book begins by demonstrating how to model asymmetric information and higher-order knowledge. It then contrasts competitive and strategic equilibrium concepts under asymmetric information. It also illustrates the dependence of information efficiency and allocative efficiency on the security structure and the linkage between both efficiency concepts. No-Trade theorems and market breakdowns due to asymmetric information are then explained, and the existence of bubbles under symmetric and asymmetric information is investigated. The remainder of the survey is devoted to contrasting different market microstructure models that demonstrate how asymmetric information affects asset prices and traders' information , which provide a theoretical explanation for technical analysis and illustrate why some investors "chase the trend." The reader is then introduced to herding models and informational cascades, which can arise in a setting where agents' decision-making is sequential. The insights derived from herding models are used to provide rational explanations for stock market crashes. Models in which all traders are induced to search for the same piece of information are then presented to provide a deeper insight into Keynes' comparison of the stock market with a beauty contest. The book concludes with a brief summary of bank runs and their connection to financial crises.

Book Numerical Methods in Economics

Download or read book Numerical Methods in Economics written by Kenneth L. Judd and published by MIT Press. This book was released on 1998-09-28 with total page 662 pages. Available in PDF, EPUB and Kindle. Book excerpt: To harness the full power of computer technology, economists need to use a broad range of mathematical techniques. In this book, Kenneth Judd presents techniques from the numerical analysis and applied mathematics literatures and shows how to use them in economic analyses. The book is divided into five parts. Part I provides a general introduction. Part II presents basics from numerical analysis on R^n, including linear equations, iterative methods, optimization, nonlinear equations, approximation methods, numerical integration and differentiation, and Monte Carlo methods. Part III covers methods for dynamic problems, including finite difference methods, projection methods, and numerical dynamic programming. Part IV covers perturbation and asymptotic solution methods. Finally, Part V covers applications to dynamic equilibrium analysis, including solution methods for perfect foresight models and rational expectation models. A website contains supplementary material including programs and answers to exercises.

Book Dynamic Noisy Rational Expectations Equilibrium with Insider Information

Download or read book Dynamic Noisy Rational Expectations Equilibrium with Insider Information written by Jerome Detemple and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: We study equilibria in multi-asset and multi-agent continuous-time economies with asymmetric information and bounded rational noise traders. We establish existence of two equilibria. First, a full communication one where the informed agents' signal is disclosed to the market, and static policies are optimal. Second, a partial communication one where the signal disclosed is affine in the informed and noise traders' signals, and dynamic policies are optimal. Here, information asymmetry creates demand for two public funds, as well as a dark pool where private information trades can be implemented. Markets are endogenously complete and equilibrium returns have a three factor structure, with stochastic factors and loadings. Results are valid for constant absolute risk averse investors; general vector diffusions for fundamentals; non-linear terminal payoffs, and non-Gaussian noise trading. Asset price dynamics and public information flows are endogenous, and rational expectations equilibria are special cases of the general results.

Book Information and Learning in Markets

Download or read book Information and Learning in Markets written by Xavier Vives and published by Princeton University Press. This book was released on 2010-01-25 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ways financial analysts, traders, and other specialists use information and learn from each other are of fundamental importance to understanding how markets work and prices are set. This graduate-level textbook analyzes how markets aggregate information and examines the impacts of specific market arrangements--or microstructure--on the aggregation process and overall performance of financial markets. Xavier Vives bridges the gap between the two primary views of markets--informational efficiency and herding--and uses a coherent game-theoretic framework to bring together the latest results from the rational expectations and herding literatures. Vives emphasizes the consequences of market interaction and social learning for informational and economic efficiency. He looks closely at information aggregation mechanisms, progressing from simple to complex environments: from static to dynamic models; from competitive to strategic agents; and from simple market strategies such as noncontingent orders or quantities to complex ones like price contingent orders or demand schedules. Vives finds that contending theories like informational efficiency and herding build on the same principles of Bayesian decision making and that "irrational" agents are not needed to explain herding behavior, booms, and crashes. As this book shows, the microstructure of a market is the crucial factor in the informational efficiency of prices. Provides the most complete analysis of the ways markets aggregate information Bridges the gap between the rational expectations and herding literatures Includes exercises with solutions Serves both as a graduate textbook and a resource for researchers, including financial analysts
