Economic dynamics: an Introduction

This book is largely based on a series of lectures which I gave at the London School of Economics in the two academic years 1947-1949. The very pleasant atmosphere provided by many good friends and the stimulating intellectual activity were highly conducive to productive effort, some of which is, I trust, manifest in this volume.

As in many things, my first debt is to Professor Lionel Robbins who originally suggested the subject of these lectures. Ralph Turvey of the London School of Economics, whose profound acquaintance with the Swedish literature is, I think, well known, wrote most of Chapter eight and the appendix to Chapter five, and in addition made his influence felt throughout the volume. Much of his contribution is based on work completely unavailable to those who, like myself, find the Scandinavian languages a closed book.

In addition I must mention the invaluable suggestions and criticisms of many friends and students. I particularly remember the contributions of David Finch, now at the International Mone tary Fund, Jan Graaff of St. John's College, Cambridge, Frank Hahn of the University of Birmingham, Gideon Rosenbluth, Reinhard Loosch, K. S. Krishnaswamy and G. S. Becker. Mr. Leslie E. Carbert of the University of California read the

manuscript and very kindly supplied a long list of suggestions and corrections which were most useful in revising it.
