Microeconomic Theory Old and New: A Student's Guide has two main goals. The first is to give advanced undergraduate and graduate students an understanding of the core model of economics: Walrasian general equilibrium theory. The text presents in detail the three building blocks of Walrasian theory—establishing Pareto efficiency in a barter economy, establishing the efficiency of competitive markets, and accounting for market failure. Each is discussed verbally, graphically, and using mathematics. After reading this book, students will have an understanding of how the seemingly disparate pieces of conventional economics fit together as a system. Although the text focuses on the intellectual framework of standard economic theory, relevant mathematical techniques are discussed. The second goal is to present contemporary extensions and emerging alternatives to the Walrasian model. Some of the theoretical inconsistencies in the model are presented, drawing on the work of Samuelson, Boadway, Chipman and Moore, Ng, and Suzamura, among others. The text then presents challenges to the basic assumptions of the Walrasian system, posed by findings in behavioral economics and evolutionary game theory. Understanding both the Walrasian system and the theoretical and experimental critiques of classical economics is essential to those who ultimately work within the traditional framework and to those looking for an alternative, making this a must read for all students of economics.

This advanced economics text bridges the gap between familiarity with microeconomic theory and a solid grasp of the principles and methods of modern neoclassical microeconomic theory.

David M. Kreps has developed a text in microeconomics that is both challenging and "user-friendly." The work is designed for the first-year graduate microeconomic theory course and is accessible to advanced undergraduates as well. Placing unusual emphasis on modern noncooperative game theory, it provides the student and instructor with a unified treatment of modern microeconomic theory--one that stresses the behavior of the individual actor (consumer or firm) in various institutional settings. The author has taken special pains to explore the fundamental assumptions of the theories and techniques studied, pointing out both strengths and weaknesses. The book begins with an exposition of the standard models of choice and the market, with extra attention paid to choice under uncertainty and dynamic choice. General and partial equilibrium approaches are blended, so that the student sees these approaches as points along a continuum. The work then turns to more modern developments. Readers are introduced to noncooperative game theory and shown how to model games and determine solution concepts. Models with incomplete information, the folk theorem and reputation, and bilateral bargaining are covered in depth. Information economics is explored next. A closing discussion concerns firms as organizations and gives readers a taste of transaction-cost economics.

Contents:- Part 1-Demand, Supply, and Markets: An Introductory Look, Part 2-Theory of Production and Cost, Part 3-Theory of the Firm and Market Organization, Part 4-Theory of Distribution, Part 5-Theory of General Equilibrium and Economic Welfare. Preface : Our goal has been to make this edition of Microeconomic Theory the most radical improvement of any revision to date. Two new chapters have been added. This book is often used as the main text in courses that are designed to bring students with no economic background up through an intermediate level.

This collection of readings provides a broad overview of the major theoretical concepts in the field and includes papers on industry size, quantity and price competition, entry barriers, product differentiation, incomplete information and general equilibrium with imperfect competition.

Models in Microeconomic Theory covers basic models in current microeconomic theory. Part I (Chapters 1-7) presents models of an economic agent, discussing abstract models of preferences, choice, and decision making under uncertainty, before turning to models of the consumer, the producer, and monopoly. Part II (Chapters 8-14) introduces the concept of equilibrium, beginning, unconventionally, with the models of the jungle and an economy with indivisible goods, and continuing with models of an exchange economy, equilibrium with rational expectations, and an economy with asymmetric information. Part III (Chapters 15-16) provides an introduction to game theory, covering strategic and extensive games and the concepts of Nash equilibrium and subgame perfect equilibrium. Part IV (Chapters 17-20) gives a taste of the topics of mechanism design, matching, the axiomatic analysis of economic systems, and social choice. The book focuses on the concepts of model and equilibrium. It states models and results precisely, and provides proofs for all results. It uses only elementary mathematics (with almost no calculus), although many of the proofs involve sustained logical arguments. It includes about 150 exercises. With its formal but accessible style, this textbook is designed for undergraduate students of microeconomics at intermediate and advanced levels.
