This graduate textbook is a "primer" in macroeconomics. It starts with essential undergraduate macroeconomics and develops in a simple and rigorous manner the central topics of modern macroeconomic theory including rational expectations, growth, business cycles, money, unemployment, government policy, and the macroeconomics of nonclearing markets. The emphasis throughout the book is on both foundations and presenting the simplest model for each topic that will deliver the relevant answers. The first two chapters recall the main workhorses of undergraduate macroeconomics: the Solow-Swan growth model, the Keynesian IS-LM model, and the Phillips curve. The next chapters present four fundamental "building blocks" of modern macroeconomics: rational expectations, intertemporal dynamic models, nonclearing markets and imperfect competition, and uncertainty. Later the book deals with growth, notably the Ramsey model, overlapping generations, and endogenous growth. Chapter 10 moves to the famous "real business cycles" (RBC), which integrate in a unified framework growth and fluctuations. The final chapters look at the issue of stabilization, how best to guard the economy from shocks, and the connections between politics and the macroeconomy. To make the book self contained, a mathematical appendix gives a number of simple technical results that are sufficient to follow the formal developments of the book.

This graduate textbook is a primer in macroeconomics. It starts from essential undergraduate macroeconomics and develops the central topics of modern macroeconomic theory in a simple and rigorous manner. All topics essential for first year graduate students are covered. These include rational expectations, intertemporal dynamic models, exogenous and endogenous growth, nonclearing markets and imperfect competition, uncertainty, and money. The book also covers real business cycles and dynamic stochastic general equilibrium models, integrating growth and fluctuations, sticky wages and prices, consumption and investment, and unemployment. Lastly, it studies government policy, stabilization, credibility, and the connections between politics and the macroeconomy. Each topic is presented in the simplest model possible while still delivering the relevant answers and keeping rigorous foundations throughout the book. To make the book fully self-contained there is a mathematical appendix that gives all necessary mathematical results.

"Macroeconomics" builds a number of macroeconomic models applying the non-Walrasian methodology. The literature on the subject has grown so rapidly in recent years that it would be unreasonable to try to give an exhaustive account of all existing models in the field. We have thus chosen to present here some models that cover as large a number of questions as possible within a simple and unified framework. We also want to bridge the gap with traditional macroeconomics while extending the analysis on various points, which be investigated by purposely making each time the simplest possible assumptions about the formation of the various prices (or, when needed, expectations) involved. This will allow us to demonstrate in a straightforward manner the synthetic qualities of the theory, both by making a natural synthesis with traditional macroeconomics, where similar simple assumptions are made, and by treating a large number of topics while using throughout a very unified macroframework.

Macroeconomics: An Introduction to the Non-Walrasian Approach provides the approach to macroeconomic theory based on the non-Walrasian method. This book presents the microeconomic concepts that can be applied in a simple and relevant manner to the fundamental topics of macroeconomic theory. Organized into five parts encompassing 14 chapters, this book begins with an overview of the fundamental concepts, describing the functioning of nonclearing markets, the role of expectations, the setting of prices by decentralized agents, and the derivation of optimal demand and supplies. This text then studies various non-Walrasian equilibrium concepts. Other chapters compare the classical and Keynesian theories of unemployment in the framework of a model. This book discusses as well the asymmetric price flexibility into the basic model. The final chapter deals with a dynamic model with explicit expectations, which allows a comparison of the employment effects of various expectations schemes and their realism. This book is a valuable resource for economists.

In recent years the field of dynamic stochastic general equilibrium models has emerged as the central field of macroeconomics. These models give a unified treatment of growth and fluctuations in a general equilibrium framework where all agents behave rationally. A particularly successful part of this field introduces imperfect competition and nonclearing markets into this framework, which also leads to the study of problems like unemployment. This timely volume gives a full account of the field, starting with the various general equilibrium traditions that ultimately led to this research area, and then describing the evolution of the models, with special emphasis on how they succeeded in representing features of dynamics that other models failed to reproduce.This collection will be an invaluable source of reference for professors and graduate students specializing in macroeconomics. It should also be of interest to students of the history of economic thought, as it shows how apparently antagonistic subfields ended up merging to produce a better synthetic theory.

The macroeconomics of imperfect competition is a field which has witnessed an almost exponential growth in the last twenty years. The reason for this success is simple as this field combines two important, and hitherto incompatible, features: On one hand, like Walrasian or new classical macroeconomics it has fully rigorous microeconomic foundations. On the other hand, like Keynesian macroeconomics (which itself lacked such foundations) it can produce underemployment of resources and macroeconomic coordination failures. This successful blend of the General Equilibrium, Keynesian and Imperfect Competition traditions has become a most influential paradigm in macroeconomics.Jean-Pascal Benassy, himself the author of several pioneering contributions, has assembled leading articles in the field and written an extensive introduction putting them and other contributions in the area into perspective. This volume will be a basic reference source for professors, students and researchers in this important and rapidly expanding field.
