Types of elasticity of demand

Types of elasticity of demand-

Elasticity of demand measures how the quantity demanded of a good responds to changes in various factors. There are several types of elasticity of demand, each focusing on different variables:

Price Elasticity of Demand (PED):

Definition: Measures the responsiveness of quantity demanded to a change in price.
Formula: ( \text{PED} = \frac{\% \text{change in quantity demanded}}{\% \text{change in price}} )
Interpretation:
- Elastic Demand (PED > 1): Quantity demanded changes more than the price.
- Inelastic Demand (PED < 1): Quantity demanded changes less than the price.
- Unitary Elastic Demand (PED = 1): Quantity demanded changes exactly as the price changes.
- Perfectly Elastic Demand (PED = ∞): Quantity demanded drops to zero with any increase in price.
- Perfectly Inelastic Demand (PED = 0): Quantity demanded remains constant regardless of price changes.

Income Elasticity of Demand (YED):

Definition: Measures the responsiveness of quantity demanded to changes in consumer income.
Formula: ( \text{YED} = \frac{\% \text{change in quantity demanded}}{\% \text{change in income}} )
Interpretation:
- Positive YED: Normal goods (demand increases as income increases).
- Negative YED: Inferior goods (demand decreases as income increases).
- Luxury Goods: YED > 1 (demand increases more than income).
- Necessities: 0 < YED < 1 (demand increases less than income).

Cross Elasticity of Demand (XED):

Definition: Measures the responsiveness of quantity demanded for one good to changes in the price of another good.
Formula: ( \text{XED} = \frac{\% \text{change in quantity demanded of Good A}}{\% \text{change in price of Good B}} )
Interpretation:
- Positive XED: Substitutes (demand for Good A increases as the price of Good B increases).
- Negative XED: Complements (demand for Good A decreases as the price of Good B increases).
- Zero XED: Unrelated goods (no effect on demand).

Advertising Elasticity of Demand (AED):

Definition: Measures the responsiveness of quantity demanded to changes in advertising expenditure.
Formula: ( \text{AED} = \frac{\% \text{change in quantity demanded}}{\% \text{change in advertising expenditure}} )
Interpretation:
- Higher AED indicates that advertising has a significant impact on demand.

These different types of elasticity help businesses and economists understand how various factors influence consumer behavior and market dynamics.
