Nonlinear and Multisectoral Macrodynamics [antikvár]

1 Introduction Kumaraswamy Velupillai I first met Richard Goodwin 15 years ago: I was 25 and he was 60 years old. The years rolled along. He left Cambridge and took up a Professorship in the University of Siena. A little later I joined him by accepting an appointment in Fiesole. We celebrated his 70th birthday in February 1983 in our house - minus our respective wives - which was set amongst the gentle hills beyond Fiesole. The ratio of our ages reached 1/2, having been less than that in the previous years! Now, this year, he has reached the venerable age of 75 and I am 15 years older than in 1973 and the ratio of our ages is greater than 1/2. In fact it is about 0.5333 and then any number of 3s as you like. He has, in the intervening years, been growing at the rate of 1.25 and I at 1.6. At this rate, it is easy to see, I could even become older than Richard Goodwin. This is the sort of linear nonsense Richard Goodwin has been trying to expose for over 40 years. The idea of a Festschrift for Richard Goodwin came up during a splendid dinner in Björn Thalberg's house in Lund when Professor Amartya Sen was visiting the University - now more than ten years ago. That is a measure of the length of time this book has been maturing. The hope is that the vintages have aged with splendour and grace, almost as Goodwin has. There is a particular sadness to report. The late Professor Leif Johansen had enthusiastically agreed to contribute for this volume. Had this book been published as early as it was conceived his prospective contribution would have enriched its contents. Another apology, and this time to Professor Amartya Sen. He it was who first encouraged and supported me to go ahead with the idea. The various complications and difficulties in his own personal life, at a crucial juncture, made it impossible for him to contribute to this particular collection of essays. To Professors Brody, Stone, Thalberg and Tinbergen I have a different kind of apology. Their enthusiastic participation was manifested in almost immediate response to my initial requests. They and almost all the others have had to wait several years to see this volume
