Preface This book champions the view that economics is a social science, and that, moreover, it may serve as a new paradigm for the social sciences. Economics is taken to be part of those sciences which deal with actual problems of society by providing insights, improving our understanding and suggesting solutions. I am aware that the way problems are addressed here has little in common with economics as it is generally understood today; most economists make strong efforts to imitate the exact sciences. Economics tends to become a branch of applied mathematics; the majority of all publications in professional journals and books are full of axioms, lemmas and proofs, and they are much concerned with purely formal deductions. Often, when the results are translated into verbal language, or when they are applied empirically, disappointingly little of interest remains. The book wants to show that another type of economics exists which is surprisingly little known. This type of economics has its own particular point of view. It centres on a concept of man, or a model of human behaviour, which differs from those normally used in other social sciences such as sociology, political science, law, or psychology. I do not, however, claim that economics is the only legitimate social science. On the contrary, economics can provide useful insights only in collaboration with the other social Vll
Vlll PREFACE sciences-an aspect which has been disregarded by mathematically oriented economics. What insights can this economic way of thinking provide? This question will be answered in the book by offering selected applications. The value of a specific approach cannot be assessed by theoretical argument only; its usefulness is revealed in conjunction with the analysis of specific problems. Part A discusses the economic approach, human behaviour and institutions being the focal point. Part B applies the economic approach the seven different areas which are outside the scope of topics dealt with in conventional economics: natural environment politics art family conflict history academia The characteristics of the approach used here becomes particularly clear when it is applied to such areas which are not normally looked at from the economic point of view. Part C deals with the limits of this approach and discusses possible further developments. In particular, ethical and psychological aspects are illuminated. This book is suitable for both beginners and advanced students of economics who are looking for an introduction into behaviourally oriented economics, also known under such terms as "Non-Market Economics," "New Political Economy," or "New Institutionalism." The book is also written for sociologists, political scientists, lawyers and psychologists who want to know more about what is sometimes called "Economic Imperialism." Finally, the book may serve the general reader who wants to know what insights modern applied economics may bring him or her. I have tried to keep the text as easy to understand as possible, and where forced to use professional terms, I have explained them. In chapter 4, which deals with the influence of economic conditions on election outcomes, an econometric (statistical) approach is used. I have attempted to show that the "economic view of the world" is not speculative and remote from reality, but is amenable to empirical analysis. The
PREFACE IX basic data and estimation results are shown in an appendix to the chapter, and are carefully explained in verbal terms. The individual chapters are based on articles which have been published in various languages in European and American academic journals. They have been completely rewritten, supplemented and brought up to the level of present day discussion. The first and ninth chapters were especially written for this volume. The initial articles were the result of many years of joint work with former assistants and now colleagues. I am grateful to Professor Iris Bohnet, Professor Hannelore Weck-Hannemann, Professor Felix Oberholzer-Gee, the late Professor Werner W. Pommerehne, Professor Barbara Krug, lic oec. Heinz Buhofer and Professor Reiner Eichenberger for permission to draw on jointlywritten articles. This second edition deletes three articles from the first edition which appeared in 1992, and adds revised versions of three articles which appeared thereafter. I am grateful to Margaret Ho-Schiitz and Matthias Benz for the support in preparing the second edition.
Acknowledgments Several chapters draw on material contained in, or are the thoroughly revised and updated versions of, articles published in various scientific journals, and are partly coauthored.
