The purpose of this book is to publish the ideas of the late Herbert Simon and sympathetic economists, on the subject of bounded rationality, economics, cognitive science and related disciplines, and to reprint some of Professor Simon's classic papers which have appeared in journals not widely read by economists. Not only on account of his Nobel Prize in Economics, but also because of the widespread applications of his ideas and theories, it is especially valuable to readers to have a book of this kind at the present time. Currently in this whole field, there is increasing emphasis on computer-related theory building. Herbert Simon, beginning from the time when microcomputers did not exist, was a pioneer of this approach. The book begins with an edited transcript of a colloquium, held between Herbert Simon and a group of Italian economists in Italy in 1988. It continues with the reprinted Simon papers and papers by three scholars, Raymond Boudon, Massimo Egidi and Riccardo Viale coming from different disciplines but holding a common interest in bounded rationality and ends with a response by a sympathetic economist, Robin Marris.

In this fourth edition of his ground-breaking work, Herbert A. Simon applies his pioneering theory of human choice and administrative decision-making to concrete organizational problems. To commemorate the fiftieth anniversary of the book's original publication, Professor Simon enhances his timeless observations on the human decision-making process with commentaries examining new facets of organizational behavior. Investigating the impact of changing social values and modem technology on the operation of organizations, the new ideas featured in this revised edition update a book that has become a worldwide classic.

Named by Public Administration Review as "Book of the Half Century," Administrative Behavior is considered one of the most influential books on social science thinking, and was referred to by the Nobel Committee as "epoch-making."

Written for managers and other professionals who wish to understand the decision-making processes at the heart of organization and management, it is also essential reading for students in business and management, economics, sociology, psychology computer science, government, and law.

What can reason (or more broadly, thinking) do for us and what can't it do? This is the question examined by Herbert A. Simon, who received the 1978 Nobel Prize in Economic Sciences "for his pioneering work on decision-making processes in economic organizations."
The ability to apply reason to the choice of actions is supposed to be one of the defining characteristics of our species. In the first two chapters, the author explores the nature and limits of human reason, comparing and evaluating the major theoretical frameworks that have been erected to explain reasoning processes. He also discusses the interaction of thinking and emotion in the choice of our actions. In the third and final chapter, the author applies the theory of bounded rationality to social institutions and human behavior, and points out the problems created by limited attention span human inability to deal with more than one difficult problem at a time. He concludes that we must recognize the limitations on our capabilities for rational choice and pursue goals that, in their tentativeness and flexibility, are compatible with those limits.

In his Mattioli Lectures, Nobel Laureate Professor Herbert A. Simon directs attention to the kinds of empirical research that are necessary for progress in microeconomics. He traces the development of neoclassical economic theory and its gradual retreat from empiricism to abstraction. He then discusses the importance of business firms to the economic system, and the need for a thoroughly empirical understanding of how organisations work and reach their decisions. Finally, he examines innovative approaches to empirical research, including experimental economics, observational methods for studying economic behaviour, and the kinds of simulation models that are needed to interpret decision process. A round-table discussion of these issues follows; the participants, in addition to Professor Simon, are Professors Claudio Dematte, Massimo Egidi, Richard M. Goodwin, Robert Marris, Aldo Montesano and Riccardo Viale.

Herbert Simon's classic work on artificial intelligence in the expanded and updated third edition from 1996, with a new introduction by John E. Laird. Herbert Simon's classic and influential The Sciences of the Artificial declares definitively that there can be a science not only of natural phenomena but also of what is artificial. Exploring the commonalities of artificial systems, including economic systems, the business firm, artificial intelligence, complex engineering projects, and social plans, Simon argues that designed systems are a valid field of study, and he proposes a science of design. For this third edition, originally published in 1996, Simon added new material that takes into account advances in cognitive psychology and the science of design while confirming and extending the book's basic thesis: that a physical symbol system has the necessary and sufficient means for intelligent action. Simon won the Nobel Prize for Economics in 1978 for his research into the decision-making process within economic organizations and the Turing Award (considered by some the computer science equivalent to the Nobel) with Allen Newell in 1975 for contributions to artificial intelligence, the psychology of human cognition, and list processing. The Sciences of the Artificial distills the essence of Simon's thought accessibly and coherently. This reissue of the third edition makes a pioneering work available to a new audience.

Experts from diverse fields, including artificial life, cognitive science, economics, developmental and evolutionary biology, and the arts, discuss modularity. Modularity-the attempt to understand systems as integrations of partially independent and interacting units-is today a dominant theme in the life sciences, cognitive science, and computer science. The concept goes back at least implicitly to the Scientific (or Copernican) Revolution, and can be found behind later theories of phrenology, physiology, and genetics; moreover, art, engineering, and mathematics rely on modular design principles. This collection broadens the scientific discussion of modularity by bringing together experts from a variety of disciplines, including artificial life, cognitive science, economics, evolutionary computation, developmental and evolutionary biology, linguistics, mathematics, morphology, paleontology, physics, theoretical chemistry, philosophy, and the arts. The contributors debate and compare the uses of modularity, discussing the different disciplinary contexts of "modular thinking" in general (including hierarchical organization, near-decomposability, quasi-independence, and recursion) or of more specialized concepts (including character complex, gene family, encapsulation, and mosaic evolution); what modules are, why and how they develop and evolve, and the implication for the research agenda in the disciplines involved; and how to bring about useful cross-disciplinary knowledge transfer on the topic. The book includes a foreword by the late Herbert A. Simon addressing the role of near-decomposability in understanding complex systems.

In this candid and witty autobiography, Nobel laureate Herbert A. Simon looks at his distinguished and varied career, continually asking himself whether (and how) what he learned as a scientist helps to explain other aspects of his life.A brilliant polymath in an age of increasing specialization, Simon is one of those rare scholars whose work defines fields of inquiry. Crossing disciplinary lines in half a dozen fields, Simon's story encompasses an explosion in the information sciences, the transformation of psychology by the information-processing paradigm, and the use of computer simulation for modeling the behavior of highly complex systems.Simon's theory of bounded rationality led to a Nobel Prize in economics, and his work on building machines that think -- based on the notion that human intelligence is the rule-governed manipulation of symbols -- laid conceptual foundations for the new cognitive science. Subsequently, contrasting metaphors of the maze (Simon's view) and of the mind (neural nets) have dominated the artificial intelligence debate.There is also a warm account of his successful marriage and of an unconsummated love affair, letters to his children, columns, a short story, and political and personal intrigue in academe.

Since the publication of Ericsson and Simon's ground-breaking work in the early 1980s, verbal data has been used increasingly to study cognitive processes in many areas of psychology, and concurrent and retrospective verbal reports are now generally accepted as important sources of data on subjects' cognitive processes in specific tasks. In this revised edition of the book that first put protocol analysis on firm theoretical ground, the authors review major advances in verbal reports over the past decade, including new evidence on how giving verbal reports affects subjects' cognitive processes, and on the validity and completeness of such reports.

In a substantial new preface Ericsson and Simon summarize the central issues covered in the book and provide an updated version of their information-processing model, which explains verbalization and verbal reports. They describe new studies on the effects of verbalization, interpreting the results of these studies and showing how their theory can be extended to account for them. Next, they address the issue of completeness of verbally reported information, reviewing the new evidence in three particularly active task domains. They conclude by citing recent contributions to the techniques for encoding protocols, raising general issues, and proposing directions for future research.

Recently there has been considerable interest in qualitative methods in simulation and mathematical model- ing. Qualitative Simulation Modeling and Analysis is the first book to thoroughly review fundamental concepts in the field of qualitative simulation. The book will appeal to readers in a variety of disciplines including researchers in simulation methodology, artificial intelligence and engineering. This book boldly attempts to bring together, for the first time, the qualitative techniques previously found only in hard-to-find journals dedicated to single disciplines. The book is written for scientists and engineers interested in improving their knowledge of simulation modeling. The "qualitative" nature of the book stresses concepts of invariance, uncertainty and graph-theoretic bases for modeling and analysis.

The Nobel Prize in Economics was awarded to Herbert Simon in 1978. At Carnegie-Mellon University he holds the title of Professor of Computer Science and Psychology. These two facts together delineate the range and uniqueness of his contributions in creating meaningful interactions among fields that developed in isolation but that are all concerned with human decision-making and problem-solving processes. In particular, Simon has brought the insights of decision theory, organization theory (especially as it applies to the business firm), behavior modeling, cognitive psychology, and the study of artificial intelligence to bear on economic questions. This has led not only to new conceptual dimensions for theoretical constructions, but also to a new humanizing realism in economics, a way of taking into account and dealing with human behavior and interactions that lie at the root of all economic activity. The sixty papers and essays contained in these two volumes are grouped under eight sections, each with a brief introductory essay. These are: "Some Questions of Public Policy, Dynamic Programming Under Uncertainty; Technological Change; The Structure of Economic Systems; The Business Firm as an Organization; The Economics of Information Processing; Economics and Psychology; "and "Substantive and Procedural Reality." Most of Simon's papers on classical and neoclassical economic theory are contained in volume one. The second volume collects his papers on behavioral theory, with some overlap between the two volumes. The second edition of Simon's widely read and referenced "The Sciences of the Artificial" was published by The MIT Press 1981 and is available in both hardcover and paperback.

We respect Herbert A. Simon as an established leader of empirical and logical analysis in the human sciences while we happily think of him as also the loner; of course he works with many colleagues but none can match him. He has been writing fruitfully and steadily for four decades in many fields, among them psychology, logic, decision theory, economics, computer science, management, production engineering, information and control theory, operations research, confirmation theory, and we must have omitted several. With all of them, he is at once the technical scientist and the philosophical critic and analyst. When writing of decisions and actions, he is at the interface of philosophy of science, decision theory, philosophy of the specific social sciences, and inventory theory (itself, for him, at the interface of economic theory, production engineering and information theory). When writing on causality, he is at the interface of methodology, metaphysics, logic and philosophy of physics, systems theory, and so on. Not that the interdisciplinary is his orthodoxy; we are delighted that he has chosen to include in this book both his early and little-appreciated treatment of straightforward philosophy of physics - the axioms of Newtonian mechanics, and also his fine papers on pure confirmation theory.

A set of related papers dealing with the meaning of causality in simulataneous dynamic equation systems. Investigation of the systems which only approximately satisfy the conditions enabling the definition of causality, leads to a set of limiting theorems concerning the dynamic behavior of such systems over time, and estimation procedures for the parameters of such systems. Implications of these theorems for some well-known propositions in economics and other social sciences are considered.

A source book for American culture in the 1960s and 1970s: "suggested reading" from the Last Whole Earth Catalog, from Thoreau to James Baldwin. The Whole Earth Catalog was a cultural touchstone of the 1960s and 1970s. The iconic cover image of the Earth viewed from space made it one of the most recognizable books on bookstore shelves. Between 1968 and 1971, almost two million copies of its various editions were sold, and not just to commune-dwellers and hippies. Millions of mainstream readers turned to the Whole Earth Catalog for practical advice and intellectual stimulation, finding everything from a review of Buckminster Fuller to recommendations for juicers. This book offers selections from eighty texts from the nearly 1,000 items of "suggested reading" in the Last Whole Earth Catalog. After an introduction that provides background information on the catalog and its founder, Stewart Brand (interesting fact: Brand got his organizational skills from a stint in the Army), the book presents the texts arranged in nine sections that echo the sections of the Whole Earth Catalog itself. Enlightening juxtapositions abound. For example, "Understanding Whole Systems" maps the holistic terrain with writings by authors from Aldo Leopold to Herbert Simon; "Land Use" features selections from Thoreau's Walden and a report from the United Nations on new energy sources; "Craft" offers excerpts from The Book of Tea and The Illustrated Hassle-Free Make Your Own Clothes Book; "Community" includes Margaret Mead and James Baldwin's odd-couple collaboration, A Rap on Race. Together, these texts offer a sourcebook for the Whole Earth culture of the 1960s and 1970s in all its infinite variety.

Nobel Laureate Herbert A. Simon has in the past quarter century been in the front line of the information-processing revolution; in fact, to a remarkable extent his and his colleagues’ contributions have written the history of that revolution in cognitive psychology.  Research in this burgeoning new branch of knowledge seeks to describe with precision the workings of the human mind in terms of a small number of basic mechanisms organized into strategies.  Newly developed computer languages express theories of mental processes, so that computers can then simulate the predicted human behavior. This book brings together papers dating from the start of Simon’s career to the present.  Its focus is on modeling the chief components of human cognition and on testing these models experimentally.  After considering basic structural elements of the human information-processing system (especially search, selective attention, and storage in memory), Simon builds from these components a system capable of solving problems, inducing rules and concepts, perceiving, and understanding. These essays describe a relatively austere, simple, and unified processing system capable of highly complex and various tasks.  They provide strong evidence for an explanation of human thinking in terms of basic information processes.
