Elasticity of Demand Chapter 4 Section 3
Demand Elasticity • Demand Elasticity: the extent to which a change in P causes a change in the Q demanded 2 types • 1. Elastic = small change in P causes a large change in Q demanded • example = fresh fruit
2. Inelastic = a change in P causes a smaller change or no change in Q demanded • Example: gas
Specific vs. General Market Examples: • Specific: Exxon Gas Station • If P increases, people would go somewhere else: therefore it is elastic (flexible) • General: All Gas Stations • If P increases, people will have to pay the increase, therefore it is inelastic (nonflexible)
Determinants of Elasticity If NO = inelastic If YES = elastic
