This advanced text introduces the principles of noncooperative game theory—including strategic form games, Nash equilibria, subgame perfection, repeated games, and games of incomplete information—in a direct and uncomplicated style that will acquaint students with the broad spectrum of the field while highlighting and explaining what they need to know at any given point. The analytic material is accompanied by many applications, examples, and exercises. The theory of noncooperative games studies the behavior of agents in any situation where each agent''s optimal choice may depend on a forecast of the opponents'' choices. "Noncooperative" refers to choices that are based on the participant''s perceived selfinterest. Although game theory has been applied to many fields, Fudenberg and Tirole focus on the kinds of game theory that have been most useful in the study of economic problems. They also include some applications to political science. The fourteen chapters are grouped in parts that cover static games of complete information, dynamic games of complete information, static games of incomplete information, dynamic games of incomplete information, and advanced topics.

The Theory of Industrial Organization is the first primary text to treat the new industrial organization at the advanced-undergraduate and graduate level. Rigorously analytical and filled with exercises coded to indicate level of difficulty, it provides a unified and modern treatment of the field with accessible models that are simplified to highlight robust economic ideas while working at an intuitive level. To aid students at different levels, each chapter is divided into a main text and supplementary section containing more advanced material. Each chapter opens with elementary models and builds on this base to incorporate current research in a coherent synthesis. Tirole begins with a background discussion of the theory of the firm.

In Part I he develops the modern theory of monopoly, addressing single product and multi product pricing, static and intertemporal price discrimination, quality choice, reputation, and vertical restraints. In Part II, Tirole takes up strategic interaction between firms, starting with a novel treatment of the Bertrand-Cournot interdependent pricing problem. He studies how capacity constraints, repeated interaction, product positioning, advertising, and asymmetric information affect competition or tacit collusion. He then develops topics having to do with long term competition, including barriers to entry, contestability, exit, and research and development. He concludes with a "game theory user''s manual" and a section of review exercises.

Once upon a time, economists saw capital account liberalization--the free and unrestricted flow of capital in and out of countries--as unambiguously good. Good for debtor states, good for the world economy. No longer. Spectacular banking and currency crises in recent decades have shattered the consensus. In this remarkably clear and pithy volume, one of Europe''s leading economists examines these crises, the reforms being undertaken to prevent them, and how global financial institutions might be restructured to this end. Jean Tirole first analyzes the current views on the crises and on the reform of the international financial architecture. Reform proposals often treat the symptoms rather than the fundamentals, he argues, and sometimes fail to reconcile the objectives of setting effective financing conditions while ensuring that a country "owns" its reform program. A proper identification of market failures is essential to reformulating the mission of an institution such as the IMF, he emphasizes. Next he adapts the basic principles of corporate governance, liquidity provision, and risk management of corporations to the particulars of country borrowing. Building on a "dual- and common-agency perspective," he revisits commonly advocated policies and considers how multilateral organizations can help debtor countries reap enhanced benefits while liberalizing their capital accounts. Based on the Paolo Baffi Lecture the author delivered at the Bank of Italy, this refreshingly accessible book is teeming with rich insights that researchers, policymakers, and students at all levels will find indispensable.

An international perspective on the financial crisis and the future of banking regulationThe financial crisis that began in 2007 in the United States swept the world, producing substantial bank failures and forcing unprecedented state aid for the crippled global financial system. Bringing together three leading financial economists to provide an international perspective, Balancing the Banks draws critical lessons from the causes of the crisis and proposes important regulatory reforms, including sound guidelines for the ways in which distressed banks might be dealt with in the future.While some recent policy moves go in the right direction, others, the book argues, are not sufficient to prevent another crisis. The authors show the necessity of an adaptive prudential regulatory system that can better address financial innovation. Stressing the numerous and complex challenges faced by politicians, finance professionals, and regulators, and calling for reinforced international coordination (for example, in the treatment of distressed banks), the authors put forth a number of principles to deal with issues regarding the economic incentives of financial institutions, the impact of economic shocks, and the role of political constraints.Offering a global perspective, Balancing the Banks should be read by anyone concerned with solving the current crisis and preventing another such calamity in the future.

From Nobel Prize–winning economist Jean Tirole, a bold new agenda for the role of economics in societyWhen Jean Tirole won the 2014 Nobel Prize in Economics, he suddenly found himself being stopped in the street by complete strangers and asked to comment on issues of the day, no matter how distant from his own areas of research. His transformation from academic economist to public intellectual prompted him to reflect further on the role economists and their discipline play in society. The result is Economics for the Common Good, a passionate manifesto for a world in which economics, far from being a "dismal science," is a positive force for the common good.Economists are rewarded for writing technical papers in scholarly journals, not joining in public debates. But Tirole says we urgently need economists to engage with the many challenges facing society, helping to identify our key objectives and the tools needed to meet them.To show how economics can help us realize the common good, Tirole shares his insights on a broad array of questions affecting our everyday lives and the future of our society, including global warming, unemployment, the post-2008 global financial order, the euro crisis, the digital revolution, innovation, and the proper balance between the free market and regulation.Providing a rich account of how economics can benefit everyone, Economics for the Common Good sets a new agenda for the role of economics in society.
