Economic Growth: A Unified Approach
'Olivier de La Grandville has written a sparkling, wide-ranging and provocative analysis of economic growth models. Noteworthy is his analysis of the difficulties in using optimal control theory and his development of an alternative approach more closely related to Solow's original growth model. He strongly emphasizes the importance of the elasticity of substitution. The work is marked by a large number of novel specific analytic results which will be of wide use.' Ken Arrow, Winner of the Nobel Prize in Economics, 1972'Olivier de la Grandville has written a remarkably original book on economic growth, questioning the suitability of the Ramsey utility function in growth modeling, and extending Adam Smith's Invisible Hands to a dynamic setting. It is provocative and deeply inspiring.' H. M. Leung, Singapore Management University'This thought-provoking book raises some fundamental questions about our future: How does competition guarantee an efficient economic growth process? What is the effect of the elasticity of substitution between capital and labour on society's optimal saving rate? Should the focus of economic policy be shifted from promoting technological progress to facilitating substitution between inputs in the production process? The author combines mathematical rigour with economic intuition to answer these topical - and possibly fateful - questions whose correct answer may well decide the future course of human development.' E. Juerg Weber, University of Western Australia'This extremely well-written book is great news for all students of neoclassical and optimal growth theories. It contains a comprehensive, systematic and integrated presentation of the fundamentals as well as some original results, new interpretations and insightful applications. Professor de La Grandville succeeds incredibly well where many others have failed, namely in the tightrope exercise of reconciling crystal clear exposition of key concepts and developments with uncompromising yet self-contained mathematical rigour. The book has many other laudable features, not the least being the author's relentless effort to provide the economic intuition behind mathematically-obtained elegant results.' Milad Zarin, Professor of Economics, University of Neuchâtel'Economic Growth: A Unified Approach separates and fuses the normative and positive aspects of growth theory in a refreshing, distinctive manner. Mathematical steps are rigorously documented, key results presented graphically and a meticulous set of problem and solutions is included. Readers will not only grasp the hard science involved but doubtless share the author's infectious enthusiasm. However, this volume transcends mere text book. From uncovering the importance of the 'normalized' production function, the promotion of the Dorfmanian and formalization of Smith's Conjecture, to challenging traditional utility analysis, this book bursts with new perspectives. It represents a significant contribution.' Peter McAdam, Research Department, European Central Bank'This book contains a very clear and profound treatment of both positive and normative growth theory, and of their unification. But if the merits of the book were only these, it would be just another excellent textbook on growth theory. What puts the book in a category of its own is the number of real goodies that it contains. These range from the Dorfmanian to the problems raised by the use of utility functions in optimal growth theory to the formal proof of the famous 'invisible hand' conjecture by Adam Smith, to cite only a few. This is an important book that every economist should read.' Giancarlo Gandolfo, Professor of International Economics, Sapienza University of Rome
