Physiocracy

Also called: Physiocrats, Physiocratic school · Topic: Schools of Economic Thought and Economic Laws · NCERT: Beyond NCERT

Meaning

Physiocracy was an 18th-century French school of economics (1750s–70s). It held that only land and agriculture produce a net surplus, the produit net, and that manufacturing and trade are "sterile". From this it argued for laissez-faire (the state keeps out of economic life) and a single tax on land.

• Formula: Produit net = Value of farm output − Cost of producing it (seed, labour and other inputs)

Physiocracy matters for two reasons:

• It was the first school to attack mercantilism. It said wealth is the products of the soil, not gold and silver [2].
• Quesnay's Tableau Économique (1758) gave economics its first circular-flow model [1].

Explanation

Core idea: "rule of nature" and the produit net

• Physiocracy means "rule of nature". It comes from the Greek physis (nature) and kratos (rule).
• The claim: only nature, working through land, creates new wealth.
• A farmer puts in seed and labour.
• The land gives back more than was put in.

• This extra is the produit net: what the land yields over and above the cost of producing it.

• Manufacturing and trade are "sterile":

• They only change the form of what the land has already produced.
• A carpenter turns wood into a table, but he adds no new wealth.
• Quesnay compared a workshop with a farm. He argued that the farm alone adds to a nation's wealth [2].

Worked example

Activity	Cost	Output value	Surplus
Farmer (seed + labour)	₹100	₹150	Produit net = ₹50 (new wealth from nature)
Weaver (yarn + his own upkeep)	₹50 + upkeep	₹50 + upkeep	Nil: only the form changed

• Physiocrats read the table this way: the farm creates ₹50 of new wealth, and the workshop creates none.

Tableau Économique (1758): the first circular-flow model

• François Quesnay was physician at the court of Louis XV and the founder of the school.
• His Tableau Économique (1758) was a diagram of payments flowing between three classes [1]:
• Productive class: farmers. They create the produit net.
• Proprietors: landlords. They receive the produit net as rent.

• Sterile class: artisans and merchants. They only change the form of goods.

• How the loop works:

• Farmers grow output and pay rent to landlords.
• Landlords spend that rent on food from farmers and on goods from artisans.
• Artisans buy food and raw materials from farmers.

• The money comes back to where it started, so the cycle can repeat.

• In the Tableau, Quesnay developed the idea of economic equilibrium. This is a state where the flows balance, so the economy can repeat itself year after year. Later economists often start from this idea [1].

• The circular flow of income in NCERT Class 12 macroeconomics comes from this model. A circular-flow model shows money and goods moving in a loop between groups in the economy.

Policy: single tax and laissez-faire

• Single tax on land (impôt unique):
• Only land yields a surplus.
• So only landowners' net income should be taxed.

• Taxing farmers, artisans or merchants would only eat into the cost of production and shrink the surplus.

• "Laissez faire, laissez passer" means "let things be made, let goods pass". In other words, free trade and less regulation.

• Quesnay wanted free trade and lower taxes [2].
• Faith in mercantilism faded in the 18th century, first because of the physiocrats. They wanted trade and industry left to follow their natural course [3].
• Key people:
• Quesnay, the founder
• A.R.J. Turgot, French finance minister 1774–76, the other leading physiocrat

Where it sits between mercantilism and Smith

• Mercantilism came before it. Mercantilists said coin and bullion were the essence of wealth. The physiocrats said wealth was only the products of the soil [2].
• Adam Smith came after it.
• Smith met Quesnay and Turgot in France in 1764–66, while he was preparing Wealth of Nations (1776).
• He took the free-trade, laissez-faire idea from them.
• He rejected the claim that industry is "sterile". For Smith, labour in all sectors, helped by the division of labour, creates wealth.

In India

• The NCERT line: Class 12 (Introduction) says, "The Physiocrats of France were prominent thinkers of political economy before Smith."
• Circular flow in Indian textbooks: The circular flow of income in NCERT Class 12 macroeconomics traces back to Quesnay's Tableau Économique (1758) [1].
• An Indian example of the physiocratic view:
• In a mainly farming economy, the land's surplus feeds everyone else. The physiocrats saw France this way.

• In India, landlords took rent from the land's surplus, and land revenue was the old base of state finance. This is the physiocrats' "proprietor" class in real life.

• A contrast in Indian planning: The Mahalanobis model (1950–90, NCERT Class 11) put heavy industry first. That is the opposite of the physiocrats' belief that only agriculture creates wealth.

• Where the idea still echoes: Ricardo's point about limited land comes back in Indian debates on farm productivity and land fragmentation. Ricardo built on the classical school, which followed the physiocrats.

Don't confuse with

• Mercantilism: wealth = stock of gold and silver, earned through export surpluses and tariffs, with the state leading. Physiocracy: wealth = products of the soil, and trade should be free.
• Classical school (Adam Smith, 1776): shares the physiocrats' laissez-faire, but says all productive labour, including manufacturing, creates wealth. Industry is not "sterile".
• Ricardo's differential rent (1817): rent comes from differences in land fertility between plots. The physiocrats' produit net is a surplus that all farming land yields over its cost.
• Keynesian circular flow of income: the modern macroeconomic model of households and firms. Its first version was the physiocrats' Tableau Économique (1758), not a classical or Keynesian model [1].

Prelims Hooks

• First circular-flow model: Quesnay's Tableau Économique (1758). It is a physiocrat work, not classical and not Keynesian [1].
• Three classes in the Tableau: productive class (farmers), proprietors (landlords) and sterile class (artisans and merchants) [1]. Trap: in physiocracy, merchants and manufacturers are the sterile class, not the productive one.
• Physiocrats: only agriculture yields a net surplus (produit net). Manufacturing and trade are "sterile". Their tax policy was a single tax on land (impôt unique).
• "Laissez faire, laissez passer" is a physiocratic slogan. Smith popularised the idea, but the phrase did not start with him.
• Key names: Quesnay (founder, physician to Louis XV) and Turgot (French finance minister 1774–76).
• "Physiocracy" = "rule of nature" (Greek physis + kratos).

Mains Points

• Farm-first versus industry-first development (GS-III):
• The physiocrats saw agriculture as the only source of surplus.
• India's Mahalanobis model (1950–90) bet on heavy industry instead.

• A balanced answer: farm surplus (food, raw materials, rural demand) is still the base that industry grows on. But the "sterile industry" claim is wrong, because manufacturing and services also add value.

• State versus market (GS-III):

• The physiocrats were the first to answer "market" against mercantilist state control. They wanted trade and industry left to their natural course [3].

• Their laissez-faire passed to Smith and later shaped the free-market thinking behind India's 1991 reforms.

• Taxing land (GS-III):

• The physiocrats argued that only the land's net income should be taxed.
• This raises a lasting question for Indian public finance: should the burden fall on unearned rent from land rather than on productive effort? It links to Ricardo's view that rent rises "while the landlord does nothing".
