RICARDIAN THEORY OF RENT
(Home Academy – Notes)
🔹 1. Introduction
The Ricardian Theory of Rent was given by
👉 David Ricardo
It explains:
How rent of land is determined
Why some land earns more rent than others🔹 2. Definition of Rent
According to Ricardo:
“Rent is that portion of the produce of the earth which is paid to the landlord for the use of original and indestructible powers of the soil.”
👉 Key Idea:
Rent arises due to fertility differences of land🔹 3. Core Concept
👉 Rent is a surplus earned by more fertile land compared to less fertile land.
Best land → High rent
Poor land → Low or zero rent🔹 4. Assumptions of Ricardian Theory
Very important for exams ⚡
Land is fixed in supply
Fertility differs among lands
Law of Diminishing Returns applies
Perfect competition
Land has original and indestructible powers
Cultivation starts from most fertile land
No alternative use of land
🔹 5. Explanation with Example
Suppose there are 3 types of land:
| Land Type | Output (Quintals) | Rent |
|---|---|---|
| A (Best) | 30 | 20 |
| B | 20 | 10 |
| C (Marginal) | 10 | 0 |
👉 Explanation:
Land C = Marginal Land → earns zero rent
Rent = Difference in productivity✔ Rent of A = 30 − 10 = 20
✔ Rent of B = 20 − 10 = 10
🔹 6. Marginal Land (Key Concept)
👉 Marginal Land is:
The least fertile land in use
Earns zero rent📌 Important:
It determines the price of output
Also called No-rent land🔹 8. Types of Rent in Ricardian Theory
Differential Rent (Main Concept)
Due to fertility differences
Core of Ricardo’s theoryScarcity Rent
🔹 9. Key Features
Rent is a differential surplus
Arises due to heterogeneity of landNo rent on marginal land
Rent does not enter price (Important!)
🔹 10. “Rent Does Not Enter Price” (Very Important 🔥)
👉 According to Ricardo:
Price is determined by cost on marginal land
Rent is a result of price, not a cause✔ Famous statement:
“Corn is not high because a rent is paid, but rent is paid because corn is high.”
🔹 11. Criticism of Ricardian Theory
Assumption of indestructible soil powers is unrealistic
Ignores alternative uses of land
Overemphasis on agriculture
Rent exists even in non-agricultural sectors
Modern theory says rent enters price
🔹 12. Important Points for Exams 🔥
Given by 👉 David Ricardo
Based on Law of Diminishing ReturnsRent = Differential surplus
Marginal land earns zero rent
Rent is price-determined, not price-determining
Also called Differential Rent Theory
