Elasticity Overview

Elasticity measures the responsiveness of one variable to changes in another, crucial for understanding demand sensitivity.
Types of elasticity include Price Elasticity of Demand (PED), Income Elasticity of Demand (YED), and Cross Elasticity of Demand (XED).

Price Elasticity of Demand (PED)

Assesses how quantity demanded reacts to price changes.
Perfectly Elastic Demand: Infinite change in quantity demanded from any price change; represented by a horizontal demand curve.
Perfectly Inelastic Demand: Quantity demanded remains unchanged despite price fluctuations; depicted by a vertical demand curve.
Inelastic Demand: Less than proportional change in quantity demanded to price change (Ed < 1); indicates consumer unresponsiveness.
Unit Elastic Demand: Equal percentage change in quantity demanded and price (Ep = 1); total revenue remains unchanged.
Elastic Demand: Greater than proportional change in quantity demanded relative to price change (Ed > 1); consumers significantly adjust purchases based on price.

Income Elasticity of Demand (YED)

Measures response of quantity demanded to changes in consumer income.
Normal Goods: Demand increases as consumer income rises.
Inferior Goods: Demand decreases as consumer income rises.

Cross Elasticity of Demand (XED)

Evaluates how quantity demanded of one good changes with price change of another good.
Positive XED (Substitutes): Price increase of one good leads to increased demand for its substitute; e.g., rising coffee prices may boost tea sales.
Negative XED (Complements): Price increase of one good results in decreased demand for its complement; e.g., higher printer prices may reduce ink cartridge demand.
Zero XED (Unrelated Goods): No relationship between the goods; price changes in one do not affect the other; e.g., bread price changes have no impact on bicycle demand.
