Elastic: Sensitive to price changes

Inelastic: insensitive to price changes

Determinants of Elasticity of Demand: Availability of substitutes, time horizon, category of product (Specific or broad), necessity vs. luxury, purchase size relative to consumer’s budget

Relatively Elastic: PED >1 (more horizontal)

Unit Elastic: PED=1

Perfectly Elastic: PED = infinity (Horizontal Line)

Relatively Inelastic: PED
