Présentation de l'éditeur

"Every few generations a great seminal book comes along that challenges economic analysis and through its findings alters men's thinking and the course of societal change. This is such a book, yet it is more. It is a "poetic" philosophy, mathematics, and science of economics. It is the quintessence of the thought that has been focused on the economic reality. Henceforce all economists must take these conclusions into account lest their analyses and scholarship be found wanting. "The entropy of the physical universe increases constantly because there is a continuous and irrevocable qualitative degradation of order into chaos. The entropic nature of the economic process, which degrades natural resources and pollutes the environment, constitutes the present danger. The earth is entropically winding down naturally, and economic advance is accelerating the process. Man must learn to ration the meager resources he has so profligately squandered if he is to survive in the long run when the entropic degradation of the sun will be the crucial factor, "for suprising as it may seem, the entire stock of natural resources is not worth more than a few days of sunlight!" Georgescu-Rogen has written our generation's classic in the field of economics."Library Journal

L'homme ne peut pas considérer la planette terre comme une corne d'abbondance aux ressources infinies, ni comme une vaste décharge à ordures pour les biens dont nous nous sommes servi et n'avons plus besoin. C'est en résumé le sens de ce livre. Mais l'auteur apporte une analyse d'une très grande profondeur sur les théories économiques et leurs fondements théoriques. Il montre entre autre à quel point la plupart des modèles écnomiques encore utilisés aujourd'hui font appel à des équations inspirées de la physique mécanique, dont les phénomènes sont reversibles, alors qu'il serait plus réaliste d'emprunter les modèles de la thermodynamique, avec ses modèles de phénomènes non réversibles dans le cas de l'économie où de plus en plus d'énergie est dépensée sans compter ou presque, se fait au prix d'une dégradation de la qualité même de cette énergie, ce que les scientifiques appellent augmentation de l'entropie. Les méthodes actuellement utilisées pour mesurer la richesse des états et même des entreprises ou des personnes encouragent une utilisation extensive de l'énergie et en conséquence un accroissement de l'entropie planétaire.

Ce livre, seulement disponible en anglais, à ma connaissance, devrait être traduit dans un maximum de langues pour le rendre accessibles à tous nos dirigeants que ce soit au niveau politique ou à celui des entreprises publiques et privées.

5.0 étoiles sur 5 Georgescu-Roegen: a missed Nobel prize 23 septembre 2012
Par ClaudioC - Publié sur Amazon.com
Format: Broché Achat vérifié
Nicholas Georgescu-Roegen's fame is due to his book The Entropy Law and Economic Process (1971) in which NGR conjugates thermodynamics and economics. But his importance for political economy goes far before the publication of this book and involves many different aspects of the analysis. While the complete theoretical framework described by NGR has been frequently contested, his analysis of the production process has been considered as truly innovative and useful, by many points of view.

5.0 étoiles sur 5 Brilliant, but not Perfect 22 mai 2006
Par Gabriel A. Lozada - Publié sur Amazon.com
Format: Broché
It must be admitted that Georgescu-Roegen's understanding of entropy was flawed. He, along with many other authors including physicists, thought entropy was a measure of disorder. It is not. That entropy is not a measure of disorder is discussed in a recent scholarly article by chemistry Prof. Frank Lambert, who has a nice web site devoted to the topic. More to the point, it was also discussed in Beard and Lozada's book about Georgescu-Roegen (p. 88, "Economics, Entropy, and the Environment: The Extraordinary Economics of Nicholas Georgescu-Roegen"). It's not easy to say what entropy actually is, but it is straightforward for scientists to measure that, say, the standard entropy of one mole of iron (about 55.8 grams of iron) is 27.7 Joules per Kelvin.

While Georgescu wasn't completely right about all of entropy's aspects, his attacks on Boltzmann's H-Theorem, and on the "information as entropy" school, show completely correct understanding of other aspects of entropy. Furthermore, in his indictment of neoclassical dynamic economics, he was the vanguard of critics who decry slavish devotion to mathematical models which assume we know the future (at least probabalistically). Absorbing Georgescu's lessons would've spared Economics Nobel Laureates Merton and Scholes their disastrous experience running the failed hedge fund Long-Term Capital Management (described in the book "When Genius Failed"): change happens, the past does not always predict the future, and the consequences of one's actions sometimes cannot be imagined by anyone. When investing money, that's a good perspective; when talking about man's effect on the environment, as Georgescu was, it's a perspective that could save the planet.

5.0 étoiles sur 5 One of Most Important Economics Works of the 20th Century 3 septembre 2001
Par mlwinkle - Publié sur Amazon.com
Format: Broché
Georgescu-Roegen argues that neo-classical economics(the dominant
form of economics at this time) is not consistent with
fundamental physical laws. The law that NC economics is most in
conflict with is the Second Law of Thermodynamics, the entropy
law. NE Economics assumes that continuous economic growth is
both desirable and possible. According to Roegen any economy is
permanently physically limited by the supply of low-entropy
matter and energy as a source for raw materials and as a sink
for our wastes. The only possible long-term source for
low-entropy energy is the sun and even this is available at a limited rate of flow.
An attempt at steady-state economics (as espoused by Herman
Daley) would be a significant improvement over the present
situation, but would still not be possible in the very long
run because of limitations on the supply of low-entropy raw
materials such as metal ores.
Roegen's point of view is fundamentally in conflict with
current economics, but we ignore his arguments at our peril.
In the not terribly distant future we will run up against
the limits that Roegen warns of.
The book is dense and difficult, but the concepts are extremely
important...
More readable books on the subject are
"Beyond Growth" and "Steady-State Economics"
by Herman Daley.

5.0 étoiles sur 5 A Law of Thermodynamics as it Applies to Economics... 23 septembre 2002
Par yygsgsdrassil - Publié sur Amazon.com
Format: Broché
...entropy is the idea that there is a growing disorder to all systems, living and otherwise. Roegen is the social philosopher who originally, successfully tied the no limit-growth of capitalism to our decreasing natural resources, our increasing endangered species lists, and our decreasing resistances to a bunch of ailments...
I remember having to study passages of this book in college and my instructor said that there's no scientific data to verify what he's saying had any merit. And, now, today, mosquitoes and terrorists and brown outs have everybody up in arms. I can't say Roegen is prophetic, but his argument, to me, always did make a whole lotta sense...and, you know, the artists and the poets seem to have always intuited the validity of this great man's message.
What has really put things in perspective for me is my further readings... I've read works from EF Schumacher ("Small is Beautiful"), Rene Dubos ("A God Within"), Jeremy Rifkin ("Entropy"), and more recently, Derrick Jensen. And they all seem to speak to needing a more humane way of capitalism which doesn't seem bent on destroying everything in it's path.
There are many other authors who may be easier to read than Roegen, but you will find, if you are in anyway interested in the fate of the world, they all refer to his seminal work here.
