Schumpeter and Georgescu-Roegen on the foundations of an evolutionary analysis: The problem of qualitative change, its methodical implications and analytical treatment
No full textDespite the frequent references to Schumpeter's work, his own encompassing methodological approach as worked out by Shionoya (1997) has hardly been considered. In this paper, it is revisited together with Georgescu-Roegen's contributions to economic methodology in view of (i) their contribution to the foundations of an evolutionary analysis in economics and (ii) their mutual complementarity and differences. Both are centred around the issue of qualitative change and its substantial analysis. Schumpeter's analytical distinction between the levels of subject matter and method and his further distinction between stationary and evolutionary economy on the level of subject matter are shown to be decisive for the structure of his analytical system and the determination of an evolutionary analysis on its basis. It is further shown that Georgescu-Roegen's contributions – his evaluation of the entropy law and his consideration of the implications of qualitative change for economic analysis – follow exactly the general structure of Schumpeter's analytical system which they refine or correct. It is argued that they provided together an encompassing general framework for the analysis of economic evolution necessarily different from, but complementary to modern static and dynamic analysis. However, they did neither state nor solve the general theoretical problem of an evolutionary analysis in their sense. --evolutionary analysis,Georgescu-Roegen,qualitative change,Schumpeter
Reconsideration of Dimensions and Curve Fitting Practice in Economics Elaborating on Georgescu-Roegen’s Economic Methodology
No full textThis paper is to examine the proper use of dimensions and curve fitting practices elaborating on Georgescu-Roegen’s economic methodology in relation to the three main concerns of his epistemological orientation. Section 2 introduces two critical issues in relation to dimensions and curve fitting practices in economics in view of Georgescu-Roegen’s economic methodology. Section 3 deals with the logarithmic function (ln z) and shows that z must be a dimensionless pure number, otherwise it is nonsensical. Several unfortunate examples of this analytical error are presented including macroeconomic data analysis conducted by a representative figure in this field. Section 4 deals with the standard Cobb-Douglas function. It is shown that the operational meaning cannot be obtained for capital or labor within the Cobb-Douglas function. Section 4 also deals with economists’ ?curve fitting fetishism?. Section 5 concludes this paper with several epistemological issues in relation to dimensions and curve fitting practices in economics.dimensions, logarithmic function, Nicholas Georgescu-Roegen, macroeconomics, Cobb-Douglas function, econometrics, curve fitting, transcendental production function
The evolutionary approach to entropy: Reconciling Georgescu-Roegen's natural philosophy with the maximum entropy framework
No full textIn Georgescu-Roegen's classical, though controversial discussion of entropy in relation to economics, the dualism of mechanical and subjective time plays a pivotal role. I argue that this fundamental distinction also inheres modern approaches to maximum entropy. Following Searle, I introduce the ontological dualism of observer independent and observer relative facts, and show that the notion of entropy also manifests this dualism, in the sense of the contextuality of measurements in experimental settings. Extending on the notion of observer relativity, I argue that the MaxEnt principle can be generalized into a framework of analyzing the evolution of (biological, technological etc.) functions under natural selection, if functions are equated with inference devices. Then, observer relativity is function relativity. In hierarchical evolutionary systems, this corresponds to the Maximum Entropy Production Principle, in the sense that functional evolution approximates gradients of maximum dissipation of energy. Against this background, the Georgescu-Roegen dualism of time translates into the dualism of observer independent entropy, which is the object of MEPP, and observer relative entropy, which is the object of MaxEnt. Both are two aspects under which evolution in general and economic evolution in particular can be analyzed. --Georgescu-Roegen,maximum entropy,observer relativity,time,hierarchical evolutionary systems,natural selection,physical concepts of information
Nicholas Georgescu-Roegen and degrowth
No full textInternational audienceAs a peculiar economist of the twentieth century, Nicholas Georgescu-Roegen gave birth to many controversies. Since the 1970s, in particular in the French language literature, Georgescu-Roegen's ecological claim has often been considered as a promotion of degrowth. In this paper, I challenge this usual interpretation. I conclude that Georgescu-Roegen might be a source of inspiration for degrowth defenders only in a very narrow sense. A cautious reading of his bioeconomic paradigm shows that Georgescu-Roegen's stance was different from the growth/degrowth debate, and might be more accurately linked with an “agrowth” option

The origins of ecological economics: Nicholas Georgescu-Roegen
No full textreservedLa presente ricerca si propone di esaminare il rilevante contributo di Nicholas Georgescu-Roegen all’ambito della teoria economica e alla promozione della sostenibilità ambientale. Eminente economista e studioso ambientale del XX secolo, Georgescu-Roegen è conosciuto per i suoi innovativi studi sull’introduzione della termodinamica in economia e per la sua visione fortemente rivoluzionaria dell’economia.
Il lavoro si apre con un’analisi introduttiva sulla vita e sul percorso professionale di Georgescu-Roegen, risaltando il concetto intellettuale in cui ha sviluppato le sue idee. Viene inoltre esposta una rassegna breve delle sue opere principali.
Il cuore dell’indagine si concentra sulle principali teorie e concetti proposti da Georgescu-Roegen, con particolare attenzione alle sue considerazioni in merito all’uso dell’entropia in economia.
L’analisi si estende alle implicazioni di tali teorie nell’ambito dell’economia ambientale e sulla sua particolare proposta sulla quarta legge della termodinamica, o legge della materia.
L’ultimo capitolo si concentra sull’attualità delle teorie di Georgescu-Roegen in un contesto di crescenti problemi ambientali globali e delle continue sfide poste dalla sostenibilità.
Viene esplorata l’influenza di Georgescu-Roegen su altri economisti e teorici dell’ambiente.
Il lavoro si conclude sull’auspicio di Georgescu-Roegen di abbracciare un approccio ecologico nell’analisi economica e nelle decisioni policy, al fine di garantire un futuro sostenibile

AND MAYBE GEORGESCU-ROEGEN WAS RIGHT
No full textGeorgescu-Roegen's name is tied to Bioeconomics. He is the founder of the discipline and he is the one who engendered the Bioeconomic program. This eight step minimal program has started many controversies over time. Our aim is to argue that Roegen's recommendations are utopian only if treated separately from the whole. Studying them in context might give us the answer we need to solve the deep human crisis, which translated into a financial and economic drama, and define a new normality
Bodies and Their Potential Parts:The Not-So-Friendly Reception of Digbean Quantity
No full textTo Digby’s contemporaries, he is a corpusculairan philosopher committed to mechanical explanations. Typically, both corpuscularianism and mechanism are taken to entail a commitment to actual parts. However, Digby rejects actualism about parts, and endorses strong potentialism. The result puzzled his contemporaries. This chapter investigates how some of his readers responded to him on this point, with the purpose of clarifying how his corpuscularianism and mechanism play out in the context of his potentialism. I argue that, rather than the impediment to corpuscularianism and mechanism that it might seem, Digby’s potentialism allows him to circumvent various problems that arise in other models.<br/
