Keynes, Uncertainty and the Global Economy THE POST KEYNESIAN ECONOMICS STUDY GROUP Post Keynesian Econometrics, Microeconomics and the Theory of the Firm and Keynes, Uncertainty and the Global Economy are the outcome of a conference held at the University of Leeds in 1996 under the auspices of the Post Keynesian Economics Study Group. They are the fourth and fifth in the series published by Edward Elgar for the Study Group. The essays in these volumes bear witness to the vitality and importance of Post Keynesian Economics in understanding the workings of the economy, both at the macroeconomic and the microeconomic level. Not only do these chapters demon- strate important shortcomings in the orthodox approach, but they also set out some challenging alternative approaches that promise to lead to a greater understanding of the operation of the market mechanism. The papers make important contribu- tions to issues ranging from the philosophical and methodological foundations of economics to policy and performance. The Post Keynesian Study Group was established in 1988 with a grant from the Economic and Social Research Council and has flourished ever since. At present (2002), there are four meetings a year hosted by a number of ‘old’ and ‘new’ uni- versities throughout Great Britain. These are afternoon sessions at which three or four papers are presented and provide a welcome opportunity for those working in the field to meet and discuss ideas, some of which are more or less complete, others of which are at a more early stage of preparation. Larger conferences, such as the one from which these two volumes are derived, are also held from time to time, including a conference specifically for postgraduates. There are presently over five hundred members who receive the Post Keynesian Study Group electronic newslet- ter and details of seminars. The Study Group has established a number of interna- tional links. As the present convenor of the Post Keynesian Study Group, I should like to thank Sheila Dow and John Hillard for the not inconsiderable time and effort they have spent in editing the proceedings and making these important papers available to a wider audience.

The conference was a wonderful occasion for me especially; I made new friends and renewed old friendships in pleasant surroundings and I heard serious, stimulating and inspiring papers and dis- cussion. The contents of the volume show that the wide-ranging interests, example and inspiration of Keynes himself guided our discussions. Much unfinished business from Keynes’s own agenda received attention: the vexed place of imperfect competition in the Keynesian system; the com- promises needed to do effective systemic analysis; the roles of knowledge, information and uncertainty in economic analysis; appropriate method- ologies; the place for econometric procedures in effective analysis; the use- fulness of the insights of Keynes and his followers for current international issues, not least taming speculators and coping with the economic igno- rance that underlies Maastricht. Because it was a gathering of Keynes scholars we were not afraid to learn from the past, from both historical events and scholars now dead. This was not piety but the application of critical intelligence combined with per- spective. I am sure that readers of the volume will get pleasure and knowledge in equal measure from it. It only remains now for me to thank the editors and the contributors for their splendidly cooperative efforts. Please read on: G.C. Harcourt Cambridge, UK ix Introduction Sheila C. Dow and John Hillard The first Keynes, Knowledge and Uncertainty conference was held in Leeds in 1993 under the aegis of the Post Keynesian Economics Study Group. The purpose of that conference was to gather together a distinguished international collection of authors to build on the impressive foundation of Keynes scholarship which had built up over the previous ten years. Not all were themselves Keynes scholars – some brought new insights from new developments in the philosophy of the physical sciences, and from post- modernism and rhetoric studies. The aim was to provide a forum for an exchange of ideas along the lines of taking forward the insights of Keynes, which were now better understood, in the development of methodology, theory and policy for the 1990s and beyond. The proceedings of this con- ference were published by Edward Elgar in 1995, under the title of Keynes, Knowledge and Uncertainty. The second Keynes, Knowledge and Uncertainty conference took place in Leeds in 1996, again under the aegis of the Post Keynesian Economics Study Group.
