Nicholas Georgescu-Roegen

Nicholas Georgescu-Roegen is a mathematics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Nicholas Georgescu-Roegen rather than just read about it. In short: Nicholas Georgescu-Roegen (born Nicolae Georgescu, 4 February 1906 – 30 October 1994) was a Romanian mathematician, statistician and economist. He is best known today for his 1971 magnum opus The Entropy Law and the Economic Process, in which he argued that all natural resources are irreversibly degraded when put to use in economic activity.

Key takeaways

  • Nicholas Georgescu-Roegen belongs to mathematics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Nicholas Georgescu-Roegen to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Nicholas Georgescu-Roegen from memory before moving on to harder problems.

Reference excerpt

Nicholas Georgescu-Roegen (born Nicolae Georgescu, 4 February 1906 – 30 October 1994) was a Romanian mathematician, statistician and economist. He is best known today for his 1971 magnum opus The Entropy Law and the Economic Process, in which he argued that all natural resources are irreversibly degraded when put to use in economic activity. A progenitor and a paradigm founder in economics, Georgescu-Roegen's work was decisive for the establishing of ecological economics as an independent academic sub-discipline in economics. In the history of economic thought, Georgescu-Roegen was the first economist of some standing to theorise on the premise that all of earth's mineral resources will eventually be exhausted at some indeterminate future point. In his paradigmatic magnum opus, Georgescu-Roegen argues that economic scarcity is rooted in physical reality; that all natural resources are irreversibly degraded when put to use in economic activity; that the carrying capacity of earth – that is, earth's capacity to sustain human populations and consumption levels – is bound to decrease sometime in the future as earth's finite stock of mineral resources is being extracted and put to use; and consequently, that the world economy as a whole is heading towards an inevitable future collapse, ultimately bringing about human extinction. Due to the radical pessimism inherent to his work, based on the physical concept of entropy, the theoretical position of Georgescu-Roegen and his followers was later termed 'entropy pessimism'. Georgescu-Roegen graduated from Sorbonne University in 1930 with a PhD in mathematical statistics with the highest honors. Early in his life, Georgescu-Roegen was the student and protégé of Joseph Schumpeter, who taught that irreversible evolutionary change and 'creative destruction' are inherent to capitalism. Later in life, Georgescu-Roegen was the teacher and mentor of Herman Daly, who then went on to develop the concept of a steady-state economy to impose permanent government restrictions on the flow of natural resources through the (world) economy. As he brought natural resource flows into economic modelling and analysis, Georgescu-Roegen's work was decisive for the establishing of ecological economics as an independent academic sub-discipline in economics in the 1980s. In addition, the degrowth movement that formed in France and Italy in the early-2000s recognises Georgescu-Roegen as the main intellectual figure influencing the movement. Taken together, by the 2010s Georgescu-Roegen had educated, influenced and inspired at least three generations of people, including his contemporary peers, younger ecological economists, still younger degrowth organisers and activists, and others throughout the world. Several economists have hailed Georgescu-Roegen as a man who lived well ahead of his time, and some historians of economic thought have proclaimed the ingenuity of his work. In spite of such appreciation, Georgescu-Roegen was never awarded the Nobel Prize in Economics, although benefactors from his native Romania were lobbying for it on his behalf. After Georgescu-Roegen's death, his work was praised by a surviving friend of the highest rank: Prominent Keynesian economist and Nobel Prize laureate Paul Samuelson professed that he would be delighted if the fame Georgescu-Roegen did not fully realise in his own lifetime were granted by posterity instead. The inability or reluctance of most mainstream economists to recognise Georgescu-Roegen's work has been ascribed to the fact that much of his work reads like applied physics rather than economics, as this latter subject is generally taught and understood today. Georgescu-Roegen's work was blemished somewhat by mistakes caused by his insufficient understanding of the physical science of thermodynamics. These mistakes have since generated some controversy, involving both physicists and ecological economists.

Life and career Nicolae Georgescu was born in Constanța, Romania in 1906. His father, of Greek descent, was an army officer, and his mother, an ethnic Romanian, was a sewing teacher at a girls school. After having lost his position in the army for disciplinary reasons, his father died when Nicolae was only eight years old.

In primary school, Nicolae excelled at mathematics, and he was encouraged by a teacher to apply for a scholarship at a secondary school, the Lyceum Mânăstirea Dealu ("Lycée of the Monastery of the Hill"), a new military prep school in the town. Nicolae won a scholarship there in 1916, but his attendance was delayed by Romania's entry into World War I. His widowed mother fled with the family to Bucharest, the country's capital, where they stayed with Nicolae's maternal grandmother during the rest of the war. Georgescu accepted a scholarship at the University of Bucharest in 1923, and earned the equivalent of a master's degree in mathematics from the university in 1926. In college, he adopted Roegen as an additional last name, using the first and the last letter of his first name, plus the first four letters of his last name, reversed, to create Roegen. Later in his life, he also changed his first name to its French and English form, Nicholas. After a year of teaching as a secondary school teacher in Constanta, Georgescu-Roegen moved to Paris to study at the Sorbonne, following a recommendation from his professor, Traian Lalescu.

Worked examples

Example 1 — a first encounter with Nicholas Georgescu-Roegen

Start with the simplest possible case. Write down what Nicholas Georgescu-Roegen claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Nicholas Georgescu-Roegen before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Nicholas Georgescu-Roegen ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Nicholas Georgescu-Roegen

In research
Nicholas Georgescu-Roegen appears in mathematics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Nicholas Georgescu-Roegen in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Nicholas Georgescu-Roegen is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1906 births, 1994 deaths, 20th-century American economists, so understanding it makes those chapters shorter.
In everyday life
Look for Nicholas Georgescu-Roegen outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
