market system is vital to understanding the tendencies and direction of the processes of adjustment. However, the bulk of economic explanation must be on the continual adjustment of market activity that is guided by relative price movements and the lure of pure economic profit and the penalty of loss. The market economy is defined in Kirzner’s system not by a state of affairs, but instead by an intricate matrix of human interdependencies in the realm of exchange relations and production decisions.
Central to Market Theory and the Price System is coordination—the critical question of any economic system. It is not just a matter of the allocation of scarce resources, but the coordination of activities such that the most willing demanders and the most willing suppliers have their plans dovetail through mutually beneficial adjustments through exchange. The unique framework Kirzner develops for microeconomic analysis, following Mises and Hayek, opens up for examination error in decision making, entrepreneurial profit, and competition as a process of discovery and learning. As Kirzner explained in an interview in 2006, in the book he was trying to bridge a gap between the neoclassical view of the market and what he understood Mises as saying about the market process. No one at the time really grasped Mises’s view of entrepreneurship or what Hayek meant regarding the role of knowledge.
For the reader of Market Theory and the Price System familiar with Kirzner’s later writings, the critical chapters to study carefully are 7 and 11 (especially 7). In both of these chapters we see the seeds of his more mature argument about the disequilibrium foundations of equilibrium economics and the anticipation of his theory of the competitive entrepreneurial market process. Chapter 7 attempts to describe the market as a learning process and to provide an explanation for equilibration. Price theory did not explain the causation of price changes, it just assumed it. Kirzner endeavored, along Hayekian lines, to make Mises’s insights on entrepreneurship and the market process available to the modern reader of microeconomic theory. One must realize the magnitude of this endeavor—something that even Rothbard failed to see.
ACKNOWLEDGMENTS
We would first like to thank wholeheartedly Israel Kirzner for his unparalleled contribution to economic science. Kirzner’s research program has deeply enriched the discipline and has shed light on some of economics’ most difficult puzzles. Economists owe him an immense intellectual debt.
The publication of the Collected Works of Israel M. Kirzner would not be a reality without the participation of Liberty Fund, Inc. We are extremely grateful to Liberty Fund, and especially Emilio Pacheco, for making this project possible. To republish Kirzner’s unique oeuvre has been on our minds since our time spent at New York University in the 1990s—where one of us was a professor (Peter) and the other a postdoc student (Frederic). We are thrilled at the idea that current and future generations of economists and other scholars will have easy access to Kirzner’s works.
Finally, we wish to thank Rosemarie Fike for her invaluable help in the publication of this volume.
Peter J. Boettke and Frédéric Sautet

During the past few years a number of competently written textbooks on price theory have appeared. The author’s excuse for adding yet another book to the elementary literature in this field is that his approach, while in no sense original, presents the subject in an entirely different light.
The approach adopted in this book views the market as a process of adjustment. In this process individual market participants are being forced continually to adjust their activities according to the patterns imposed by the activities of others. Market theory then consists essentially in the analysis of these step-by-step adjustments and of the way the information required for these adjustments is communicated. Equilibrium positions are not, as in other books, treated as important in themselves. They are rather seen as merely limiting cases where the market process has nothing further to do, all activities being already mutually adjusted to the fullest extent.
Despite the importance attached to the implications of the approach adopted here, users of this book will find relatively few major substantive departures from price theory as it is usually presented. The principal areas where major differences will be found arise out of the drastically reduced attention paid to perfect competition. Presuming the basic course in general economics, this book is designed for an undergraduate course in intermediate price theory.
For the rest, an author can hardly hope to have escaped revealing his own proclivities, biases, and predilections. Determined efforts have been made to subordinate geometry to economic reasoning. Whatever the author may have learned from Marshall, Edgeworth, and J. B. Clark, this book probably will reveal that he has learned more from Menger, Böhm-Bawerk, and Wicksteed.
Besides his indebtedness to the literature, the author must acknowledge much kind help received from several persons during the preparation of this book. To his teacher Ludwig von Mises, above all, he owes his appreciation of the market process. In addition to reading the finished manuscript, Professor Mises offered many helpful suggestions during its completion. It is with deep pleasure that the author dedicated this volume to him upon the attainment of his eightieth year.
The author is grateful to his colleagues at New York University, as well as to his students, for stimulating discussions on a number of points. To Professor L. M. Lachmann of the University of Witwatersrand, South Africa, he is indebted for several valuable insights that were made use of in exposition. The author’s wife has patiently and cheerfully endured, aided, and encouraged throughout the book’s preparation. To all these he is grateful; none of them is to be held responsible for all that remains unsatisfactory.
Israel M. Kirzner
