Book Description
Economic theory of the last fifty years has been dominated by the paradigm of General Equilibrium Theory, based on the scientific work of Walras-Pareto-Cassel-Wald-Hicks-Arrow-De breu-McKenzie. Some of its grounding assumptions are: all prices are fully flexible; an auctioneer appropriately manipulates all prices according to the law of supply and demand; every con sumer has only one budget constraint; all agents are perfectly informed; no actions are taken by agents before a vector of prices has been found such that all markets clear. Indeed, when all markets clear every agent can implement her/his chosen (opti mal) action and nobody is urged to change his/her decisions. Under these assumptions it is generally said that in a (one pe riod, competitive) general equilibrium model there is no place for money. The present monograph takes general equilibrium as the ba sis on which to build the model presented. But its first aim is to completely dispense with the Walrasian auctioneer by giving firms the task of choosing their output price~ period after period.

Book Description
Posing a major challenge to economic orthodoxy, Imperfect Knowledge Economics asserts that exact models of purposeful human behavior are beyond the reach of economic analysis. Roman Frydman and Michael Goldberg argue that the longstanding empirical failures of conventional economic models stem from their futile efforts to make exact predictions about the consequences of rational, self-interested behavior. Such predictions, based on mechanistic models of human behavior, disregard the importance of individual creativity and unforeseeable sociopolitical change. Scientific though these explanations may appear, they usually fail to predict how markets behave. And, the authors contend, recent behavioral models of the market are no less mechanistic than their conventional counterparts: they aim to generate exact predictions of "irrational" human behavior. Frydman and Goldberg offer a long-overdue response to the shortcomings of conventional economic models. Drawing attention to the inherent limits of economists' knowledge, they introduce a new approach to economic analysis: Imperfect Knowledge Economics (IKE). IKE rejects exact quantitative predictions of individual decisions and market outcomes in favor of mathematical models that generate only qualitative predictions of economic change. Using the foreign exchange market as a testing ground for IKE, this book sheds new light on exchange-rate and risk-premium movements, which have confounded conventional models for decades. Offering a fresh way to think about markets and representing a potential turning point in economics, Imperfect Knowledge Economics will be essential reading for economists, policymakers, and professional investors.

Book Description
'To non-economists, it is hard to understand why economists spend so much effort on the competitive model whereas the world seems to be replete with large and powerful economic actors. In this respect, Jean Gabszewicz is atypical: he has spent most of his research time working on imperfectly competitive markets. However, instead of restricting himself to partial equilibrium analyses, he has tackled from the outset the problem of imperfect competition in a system of interrelated markets with the aim of studying how market power is spread throughout the whole system. This is one of the most challenging and fascinating tasks that economists face. But this is also a very hard one, and may explain why so few have tried. This book builds on the seminal contributions of Cournot and Edgeworth and does not intend to provide a full-fledged answer to the many questions raised by the general theory of imperfect competition. However, by presenting in a transparent way most of the problems that lie at the roots of imperfect competition in general equilibrium and by proposing various elegant solutions, it paves the way to any future research in the field. No doubt it will become a basic reference in the long run. The economics profession should thank Jean Gabszewicz for a fresh and daring way of looking at market power.' - Jacques Thisse, Université Catholique de Louvain, Belgium and École Nationale des Ponts et Chaussées, France Jean Gabszewicz's new book is devoted to the study of strategic multilateral exchange. Contrary to the classical competitive paradigm in which agents are assumed to behave as price takers, here traders are allowed to consciously behave as strategic agents who aim to influence trade to their own advantage. This is usually done in oligopoly theory using a partial equilibrium approach while in this case a system of interrelated markets is considered.

Book Description
In this book, Jean-Pascal Benassy attempts to integrate into a single unified framework dynamic macroeconomic models reflecting such diverse lines of thought as general equilibrium theory, imperfect competition, Keynesian theory, and rational expectations. He begins with a simple microeconomic synthesis of imperfect competition and nonclearing markets in general equilibrium under rational expectations. He then applies this framework to a large number of dynamic macroeconomic models, covering such topics as persistent unemployment, endogenous growth, and optimal fiscal-monetary policies. The macroeconomic methodology he uses is similar in spirit to that of the popular real business cycles theory, but the scope is much wider. All of the models are solved "by hand," making the underlying economic mechanisms particularly clear.

Book Description
An important recent advance in macroeconomics is the development of dynamic stochastic general equilibrium (DSGE) macromodels. The use of DSGE models to study monetary policy, however, has led to paradoxical and puzzling results on a number of central monetary issues including price determinacy and liquidity effects. In Money, Interest, and Policy, Jean-Pascal Benassy argues that moving from the standard DSGE models - which he calls "Ricardian" because they have the famous "Ricardian equivalence" property-to another, "non-Ricardian" model would resolve many of these issues. A Ricardian model represents a household as a homogeneous family of infinitely lived individuals, and Benassy demonstrates that a single modification-the assumption that new agents are born over time (which makes the model non-Ricardian)-can bridge the current gap between monetary intuitions and facts, on one hand, and rigorous modeling, on the other. After comparing Ricardian and non-Ricardian models, Benassy introduces a model that synthesizes the two approaches, incorporating both infinite lives and the birth of new agents. Using this model, he considers a number of issues in monetary policy, including liquidity effects, interest rate rules and price determinacy, global determinacy, the Taylor principle, and the fiscal theory of the price level. Finally, using a simple overlapping generations model, he analyzes optimal monetary and fiscal policies, with a special emphasis on optimal interest rate rules
