This paper introduces a new theory of market incompleteness based on the information transmission role of prices and its adverse impact on the provision of insurance in financial markets. We analyze a simple security design model which endogenizes not only the characteristics of each individual security but also the number of securities. Agents have rational expectations and differ in information, endowments, and attitudes toward risk. When markets are incomplete, equilibrium prices are typically partially revealing, while full revelation is attained with complete markets. The optimality of complete or incomplete markets depends on whether the adverse selection effect is stronger or weaker than the Hirshleifer effect, as new securities are issued and prices reveal more information. When the Hirshleifer effect dominates, an incomplete set of securities is preferred by all agents, and generates a higher volume of trade.

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

This work, now in a thoroughly revised second edition, presents the economic foundations of financial markets theory from a mathematically rigorous standpoint and offers a self-contained critical discussion based on empirical results. It is the only textbook on the subject to include more than two hundred exercises, with detailed solutions to selected exercises. Financial Markets Theory covers classical asset pricing theory in great detail, including utility theory, equilibrium theory, portfolio selection, mean-variance portfolio theory, CAPM, CCAPM, APT, and the Modigliani-Miller theorem. Starting from an analysis of the empirical evidence on the theory, the authors provide a discussion of the relevant literature, pointing out the main advances in classical asset pricing theory and the new approaches designed to address asset pricing puzzles and open problems (e.g., behavioral finance). Later chapters in the book contain more advanced material, including on the role of information in financial markets, non-classical preferences, noise traders and market microstructure. This textbook is aimed at graduate students in mathematical finance and financial economics, but also serves as a useful reference for practitioners working in insurance, banking, investment funds and financial consultancy. Introducing necessary tools from microeconomic theory, this book is highly accessible and completely self-contained. Advance praise for the second edition: "Financial Markets Theory is comprehensive, rigorous, and yet highly accessible. With their second edition, Barucci and Fontana have set an even higher standard!"Darrell Duffie, Dean Witter Distinguished Professor of Finance, Graduate School of Business, Stanford University "This comprehensive book is a great self-contained source for studying most major theoretical aspects of financial economics. What makes the book particularly useful is that it provides a lot of intuition, detailed discussions of empirical implications, a very thorough survey of the related literature, and many completely solved exercises. The second edition covers more ground and provides many more proofs, and it will be a handy addition to the library of every student or researcher in the field."Jaksa Cvitanic, Richard N. Merkin Professor of Mathematical Finance, Caltech "The second edition of Financial Markets Theory by Barucci and Fontana is a superb achievement that knits together all aspects of modern finance theory, including financial markets microstructure, in a consistent and self-contained framework. Many exercises, together with their detailed solutions, make this book indispensable for serious students in finance."Michel Crouhy, Head of Research and Development, NATIXIS

When can policy makers use policy-relevant information from financial market prices and how does policy affect price informativeness? I analyze a novel setting with noise where a policy maker tries to infer information about a state variable from prices to improve policy decisions, and policy in turn affects asset values. I derive a necessary and sufficient condition for the possibility of information revelation in equilibrium, which might not be possible if the policy reaction to prices punishes traders for revealing their information. If the policy maker is uninformed, then policy objectives do not change price informativeness, but they do if the policy maker has independent information about the state. I also analyze policy maker transparency, and find that policy makers with objectives having a large impact on asset values should publish their information before trading to make prices more informative. In other cases, intransparency can be optimal.

Aimed at advanced undergraduate and graduate students in economics, banking, and finance, this is a core textbook for the financial markets, institutions, and regulation option of courses in financial economics. It integrates modern theories of asymmetric information into the analysis of financial institutions, relating the theory to current developments. The text begins with an analysis of adverse selection in retail financial products like life assurance before looking at open capital markets where trades and prices provide information. It then progresses to the more complex areas of corporate governance and financial intermediation in which information is concealed or confidential and moral hazard and verification problems become important. These chapters study the various mechanisms that the financial markets have developed to allow investors to delegate the management of their assets to others. This analysis is used to show how regulation can reduce the risk of financial failure and how legal, accounting, and regulatory mechanisms can help shape a country's corporate and financial architecture. These difficult theoretical concepts are conveyed through the careful use of numerical illustrations and topical case studies. Each chapter ends with a set of exercises to test and reinforce students' comprehension of the material. Worked solutions are provided for the numerical exercises.
