Introduction
Law of Demand is a key principle in economics. It explains how the quantity demanded of a product changes when its price changes, all other factors being constant. This is called the 'ceteris paribus' condition.
CISCE: Class 12
Statement
When the price of a commodity falls, people buy more of it. When the price rises, people buy less — other factors remain the same.
Maharashtra State Board: Class 12
CISCE: Class 12
CISCE: Class 12
Formula: Law of Demand
Dx = f(Px, Pn, Y, T)
Where Dx = Demand for commodity x,
Px = Price of the commodity x,
Pn = Price of related commodities,
Y = Income of the consumer,
T = Taste.
Maharashtra State Board: Class 12
CISCE: Class 12
CISCE: Class 12
Definition: Law of Demand
- Marshall: “Amount demanded increases with a fall in price and diminishes with a rise in price, other things being equal.”
- Samuelson: “People buy more at lower prices and less at higher prices, ceteris paribus.”
- Ferguson: “The quantity demanded varies inversely with price.”
CISCE: Class 12
Assumptions
- The consumer’s income does not change.
- Tastes and preferences do not change.
- Prices of similar/related goods stay the same.
- Population size and structure stay constant.
- No expectation of future price changes.
CISCE: Class 12
Tabular Representation
| Price per Kg (₹) | Quantity Demanded (Kgs) |
|---|---|
| 5 | 10 |
| 4 | 20 |
| 3 | 30 |
| 2 | 40 |
| 1 | 50 |
As price drops, quantity demanded rises — showing an inverse relation.
CISCE: Class 12
Demand Curve
Maharashtra State Board: Class 12
CISCE: Class 12
CISCE: Class 12
Key Points: Law of Demand
- There is an inverse relation between price and quantity demanded.
- All other factors must remain constant for the law to apply.
- The demand curve always slopes downwards.
