[…] the essence of development consists of the organizational and flexible power to create new processes rather than the power to produce commodities by materially crystallized plants.
N. Georgescu-Roegen 1971, p. 275

1 The degrowth debate

There is a vivid, on-going debate about “what degrowth is” in the scientific literature. The researchers involved having very diverse background, e.g. philosophy, political science, economics, ecology, engineering. I try here to highlight both the points in common and the differences, in an interdisciplinary and pragmatic perspective, and – possibly – smoothing the divisions.

On the political side, right and left policymakers are divided about the crisis cure, debating about the degree of fiscal redistribution (income tax, Tobin tax, minimum and maximum wages) and state spending (infrastructures for schools, roads, trains, public water resources). Degrowth perspective lying at the extreme left of the political spectrum. This is – I believe- mainly due to the fact that crisis means unemployment and the degrowth concept and proposal sounds as heresy to the majority of representatives since GDP de-growth is associated with increase in unemployment.

On the academicals side, van den Bergh (2011) and Kallis (2011) recently synthesized the ecological and degrowth economics perspectives respectively. The former detailing the terrain vague of degrowth proponents: GDP, consumption, work-time, radical or physical degrowth? van den Bergh detailed an ontological critique: “GDP degrowth means a blunt instrument of environmental policy which reverses the causality between policy and growth as it is normally understood. Instead of putting a good policy first and then seeing whether degrowth is a consequence, the degrowth strategy is to set the aim of degrowth first and then hope that the environment will come out well” (van den Bergh, 2011, p. 882). Instead, he proposes “a-growth” as a political strategy based on beyond-GDP indicators, international climate agreement, different work-time norms, advertisement regulations, sustainability school programs and technological specific incentive policies.

Kallis’ defense of degrowth hypothesis (Kallis 2011, 2012) starts by widening the definition: “It is an umbrella keyword, a multifaceted framework that gives purpose and connects different policies and citizen initiatives. And it is a concept that builds on a deep and long philosophical, cultural, anthropological and institutional critique of the notions of growth and development..” (Kallis 2011, p. 874). He specifies then: “Sustainable degrowth can be defined form a ecological-economic perspective as a socially sustainable and equitable reduction (and eventually stabilization) of society’s throughput” (ibid.). Throughput  meaning materials and energy, whose reduction implies GDP reduction because of the dependence of economic growth on non renewable energy and materials (decoupling and efficiency are illusionary)1.

The pessimistic view of the degrowth movement about the possibilities offered by technological progress to allow growth with less resources (decoupling) is shared by the societal metabolism proponents (Sorman and Giampietro 2012, Giampietro et al. 2011). They defy the Environmental Kuznets Curve (EKC) and decoupling hypothesis using a multi-scale analysis (MuSIASEM) detailing energy, people (measured in hours) and money at the economic subsector level. Their analysis denies the possibility of reduced exhaustible resource dependence, showing instead how it is the externalization of “heavy” (in energy and materials) production in emerging economies (e.g.  BRICS) which explains the reduced energy, pollution and waste in modern, service-based economies.

A major disagreement between societal metabolism and ecological economics supporters with Kallis (and the degrowth partisans in general) concerns the (shorter) working time as part of the economic downsizing. Sorman and Giampietro (2012) explain the societal metabolism approach to analyze the present crisis: high unemployment and low wages in a world dealing with less energy and materials might well lead the way to labour intensive products and this is likely to equal more working hours as the diminishing high capital productivity will have to be compensated by increasing low productivity labour. Sorman and Giampietro (2012) use MuSIASEM (Giampietro and Mayumi 2000a, b) to show how the service and government (S&G or “dissipative”) sector employs the majority of people and does not produce neither energy, products or food, but services. On the other hand it belongs to the energy and mining (EM), agricultural (AG) and building and manufacturing (BM) productive (or “hypercyclic”) sectors to “feed” the rest of society. This “hypercyclic” sector is characterized by very little employment and huge capital and energy resources, thus a reduction of available energy will hit badly both “hypercyclic” and (fragile) “dissipative” societal sector. Also a low output/input renewable energy resource – to substitute high output/input fossils – will not change the course of things. No smooth transition is in sight according to the societal metabolic researchers.

2 An intuitive rationale of the economic process

I propose here a schematic representation of the economic process, centered on supply and demand, to highlight the field of intervention.

On the supply side. The entrepreneur theory postulate he maximizes profit, in reality he tries to maximize output, expanding the firm, increasing the capital etc. In search of economies of scale. With respect to neoclassical economic theory, firms are not atomistic, rather giants with sophisticated financial architecture.

Modern superstructure. The quantity-maximized products are first structured by the marketing departments, then advertized by the pervasive media world, which creates an fast-changing collective imaginary of ever-increasing consumption ambitions. Magazines, TV and internet keep feeding the demand and generating a collective oblivion about both material waste and depletion (double myopia).2

On the demand side. The consumer identifies consumption with happiness, social success and status symbol are no more related to fixed (middle-ages ) classes. Money moves between social strata, but inequality increased greatly also. Income inequality has increased since the ’80 by so-called “supply-side” fiscal policies aimed at reducing the fiscal burden on high income and enterprises.

These policies (“reaganomics” or “thatcherism”, inspired by Milton Friedman word-wide influence) have meant important gains for few riches and reduced income for the State. A fiscal deficit often compensated with cuts on schools, hospitals, infrastructures and other public services. Moreover, this extra gain very seldom is directed to productive investment, but rather goes to more financial investments to feed the international paper-economy (local impoverishment).

The markets globalization and concentration (fall of Eastern Europe, WTO agreements) has been helped in the past 20 years by the diffusion of information and communication technology. Companies have merged, rationalized their production in function of resources, energy, labour costs and fiscal opportunities. This was possible thanks to cheap fossil energy: cheap energy = more energy = more capital = more production (see below). This process went together with less labour and low wages, because of (accounted) low labour productivity in highly-capitalized firms.

On the other hand, the expansion of credit, motivated by new financial products vehiculated via electronic, instant trading, resulted in a continuous bet on growth, generating an ever-increasing debt. Virtual money (financial products value) is estimated to be 1000 times world GDP.

The end of easy, abundant energy broke the circle: 100$/barrel oil is the missing link between 1) the inner fragility of the financial bet; 2) the minimum margins of the producers and 3) the lowered purchasing power of impoverished consumers. This – I believe – explains the crisis.

It is this (unknown?) feature of the capitalistic economic process which clashes with sustainable (be it stable or reduced) throughput. A clear example is offered by public utilities dealing with electricity, gas, water or waste: should they try to “sell more”? Clearly not.

To help solving this, energy and material statistical accounting (OECD 2008a, b) is a crucial issue (and needs  public investment in statistical offices) in order to enable the evaluation of the effective sustainability of societies in the close future. Nevertheless, at the core of capitalistic process there are:

  • The rational output maximization attitude of the firm
  • The emotional eros3 for new, more and more expensive4 goods of the consumer

Both mechanisms create a continuous demand for energy and materials. In standard economic analysis,  this phenomenon is known energy (and materials) complementarity with GDP (Daly 1997). To keep the standard production function representation for a while, we can mention that the flexibility of the economic process with respect to energy price and quantity shock relates to the elasticity of substitution between inputs.

It is a long debate going back to early economic history (Allen 1938, Berndt and Wood 1975, Blackorby and Russell 1989, Frondel and Schmidt 2004, Koetse et al. 2008) recently being investigated by Fiorito and van den Bergh (under review), whose results show how energy and capital are not good substitutes, but rather complementary, even in periods of cheap, abundant energy.

Moreover, the now huge influence of the financial sector on the real economy explains the ever increasing pressure of financial over the manufacturing  sector (Gallino 2011). This translates into more sales for “Main street”. Firms need exponential sales…to survive!

Mayumi and Tanikawa (2012: 20) synthesized well an integrated view of the economic process:

According to Georgescu-Roegen the economic process does not produce goods and services, but it produces a reproducible system, via the establishment of an integrated process of production and consumption of goods and services. When dealing with the analysis of the economic sectors – those producing added value – they not only produce goods and services, but also produce those processes required to produce and consume goods and services. When considering the whole socioeconomic system, it is the integrated action of the productive economic sector and the sector of final consumption which has to be considered. Using Georgescu-Roegen’s terminology, the economic process has the goal of reproducing and expanding the various fund elements defined simultaneously across different levels and scales, by using disposable flows. Following Georgescu-Roegen, we can conclude that an economy not only produces goods and services, but more importantly produces the processes required for producing and consuming goods and services“.

3 A feasible recipe?

In the last years, the historical need for social justice and equity between people (classes, in Marxist sense) has evolved into the domain of ecological sustainability, the environmental dimension having primed on the mere economic/monetary one. The commodity/food (2007), energy (2008), financial (2008 to present) and economic (2009 to present) crisis have shifted the sustainability concept from the political/ecological to the moral/psychological domain. In bullet points there is a wide understanding of the general public about:

  • both global warming and resource scarcity;
  • nature’s “economic” limits (energy/resource supply and emissions/wastes sink capacity);
  • finance’s eternal bet on exponential growth (“Ponzi” economics, Giampietro et al. 2011);
  • national and international inequalities rise (99%, indignados and occupy movements);
  • the consequences of the 4 points above in everyone’s wallet:

All this – I believe – have brought ethical and ecological to become synonyms in the collective consciousness.

On a political side, stabilizing the (exponential growth) influence of finance toward real economy goes along with some fiscal actions shifting the burden form labour to capital. Namely,

  • Tobin tax on financial (short term) transactions;
  • strict derivatives regulation (e.g. no derivatives on commodities, like in India, Credit Default Swap regulation);
  • re-establishment of the separation between traditional and investment banks (e.g. Glass-Steagall Act);
  • fiscal gains for strictly/serious green investment funds.

On the demand side, the specific reduction in income inequality is the basis for a socio-political change toward sustainability, because only dismantling money fetishism it is possible to stop low-life, high energy/material intensity products.

To reduce both inequality and (myopic) consumeristic attitude it is natural to envisage:

  • minimum and maximum wages rules
  • job guarantee program (continuous training for the unemployed)
  • progressive income tax
  • public and non-motorized transport infrastructure (trains, trams, cycling lanes)
  • woods, rivers and material waste integrated restoration process

Setting the basis for a different homo at the political level is necessary to stimulate non-monetary, solidarity, cultural restoration activity. Such a path will only be economically profitable in the long term, but in the short run can gratify many, reducing distress and crime. In fact the necessary degrowth everybody agrees means less monetary activity not less work, which, important to say will be necessary anyway. An example is food: the transition to low fossil energy and material society implies a population flow to the land where small scale, local, organic agriculture will be the norm. In this sense the emancipation from the land was really temporary (Mayumi 1991).

3 storie false

10 Febbraio 2010 Nessun commento

Da quando ho cominciato a interessarmi della natura entropica del processo economico, non riesco a liberarmi di un’idea: è disposto il genere umano a prendere in considerazione un programma che implichi una limitazione della sua assuefazione alle comodità esosomatiche? Forse il destino dell’uomo è quello di avere una vita breve, ma ardente, eccitante e stravagante piuttosto che un’esistenza lunga, monotona e vegetativa. Siano le altre specie le amebe per esempio, che non hanno ambizioni spirituali, a ereditare una terra ancora immersa in un oceano di luce solare. NGR

Tre storie false sull’energia e la sostenibilità

(da rivedere per avere un dibattito sensato sul futuro)

(1) Presto saremo in grado di far funzionare le nostre economie con le energie alternative

Al contrario, rimarremo comunque dipendenti dall’energia fossile per almeno altri 15/20 anni (non è possibile avere una transizione più rapida, a causa di molte rigidità). Quali sono le implicazioni di questo punto? (distorsione del mercato a causa delle alleanze politiche tra paesi ricchi e multinazionali, pesanti rischi  per le economie dei paesi  poveri)

(2) Dobbiamo trovare fonti alternative di energia per continuare a fare quello che facciamo adesso

E’ vero il contrario, abbiamo bisogno di cambiare il nostro modello di produzione e di consumo, per poter utilizzare fonti energetiche alternative. Questo è alla radice del malinteso della green economy e delle energie alternative. Le fonti energetiche alternative possono essere competitive se utilizzati all’interno di un diverso modello di produzione e consumo. Ma se vogliamo solo sostituire l’attuale produzione (a base di petrolio) con le fonti alternative, le fonti alternative risulteranno più costose di quelli tradizionali (è per questo che hanno bisogno di sovvenzioni);

(3) E’ possibile risolvere il problema dei cambiamenti climatici, regolando (a piacere) il nostro consumo di energia, mediante l’attuazione di politiche semplici e indolori

Al contrario, il rapporto tra performance economica e consumo di energia è molto complesso e difficile da modificare. In altre parole, è molto improbabile che saremo in grado di aumentare il nostri consumi globali di energia oltre il livello raggiunto nel 2008 (picco del petrolio) ed è molto improbabile che saremo felici di ridurre i nostri consumi di energia (dato che ridurre i consumi energetici si traduce in crisi economica mondiale). L’attuale modello di consumo di energia è piuttosto stabile e difficile da modificare: è molto improbabile che politiche semplici e indolori, sulla base di incentivi di mercato, abbiano successo.


L’ultimo fax di Georgescu Roegen

25 Maggio 2009 Nessun commento

Sul tema delle crescita economica (possibile? come?) presento un testo inedito di Nicholas Georgescu-Roegen, da lui inviato via fax a Kozo Mayumi nel 1992.

Nel testo l’economista rumeno esterna la personale condizione di isolamento in cui si trova, denunciando al contempo sia le sirene della crescita sostenibile che la fede di economisti e politici in modelli econometrici triti e ritriti.

La lettera è importante per capire la difficoltà dell’uomo, che alla soglia dei 90 anni si trova ad essere marginalizzato sia da parte degli economisti ortodossi che di quelli ecologici!

Il fax originale di G-R:

‘I am afraid that this letter may come too late to you, so late that you may feel like not even read it. But, my dear Kozo, you are still very young for being aware of the conjuring tricks used by many cliques of “scholars”. Why, today many economists and ecologists are amassing money over money by selling two kinds of snake oils: one sings the lullaby of sustainable growth for abundant funding, the other sells to the still unaware nation the simplest econometric models of growth that have been duly exposed and overexposed. Drop me a line, even two, if you can forgive the faults of the old man with whom you once wanted to discuss things and problems as well’


Temo che questa lettera ti arrivi troppo tardi, così tardi che che potresti non avere neppure voglia di leggerla. Ma, mio caro Kozo, tu sei ancora troppo giovane per essere cosciente dei trucchi da congiurati di molteplici cricche di accademici. Poiché, oggi molti economisti ed ecologisti stanno ammassando enormi quantità di denaro vendendo due varietà di olio di serpente : uno canta la ninna nanna della crescita sostenibile, dietro abbondanti finanziamenti, l’altro vende i modelli econometrici della crescita più semplici, già abbondantemente spiegati.

Petrolio a 60 dollari

Dopo “l’emorragia” dell’anno scorso che, secondo noi, è tra le cause della crisi finanziaria, arriva il “salasso” di un dolce e continuo rialzo. Il barile infatti sta riprendendo a crescere (vedi sotto), nonostante i PIL siano in calo generalizzato.

Questo fenomeno, in un momento di economia genuflessa ad invocare “Crescita!” rischia di essere non un ma il fattore che lo impedisce.


Petrolio ed auto vanno assieme: la seconda industria perde 41 miliardi nel 2008; ma ci sono le

Buone notizie

Meno male che arriva lo scooter ibrido e – soprattutto – che l’auto a idrogeno Honda la farà, lo dice il vecchio Takeo.

Ricordate una data 2014 (o 2015).

Perche la sinistra…il chiasmo del rosso e del verde

7 Giugno 2008 1 commento


L’articolo del Prof. Ruffolo Ma perché la sinistra dovrebbe vincere? è bellissimo. Lucido e saggio. Leggendolo, sembra di vedere la recente sconfitta del PD su un campo di battaglia concettuale. Un dipinto in cui agiscono carnali legioni di elettori italiani, oggi appartenenti ai vari partiti. Manovre a pinza nei dibattiti di piazza delle cavallerie/ideali degli italiani di sinistra e di destra a formare un chiasmo di valori e politiche, presenti e passate che, intuitivamente, spiega benissimo l’attuale impedimento della sinistra d’incarnare il consenso della maggioranza. E’, forse, la causa primaria del rallentamento del progresso economico mondiale.
