Elasticity and Price Elasticity of Demand

Elasticity Overview

• Elasticity Concept: Pertains to how responsive one variable is to changes in another.
• Rubber Band Analogy:
  • Elastic: Significant change with small adjustments (like a stretch in a rubber band).
  • Inelastic: Little to no change despite large adjustments (like a stiff rubber band).

Price Elasticity of Demand

• Definition: Measures how much quantity demanded changes in response to a price change.
• Elastic Demand:
  • Small price change leads to large change in quantity demanded.
• Inelastic Demand:
  • Large price change results in minimal change in quantity demanded.
• Key Understanding:
  • Elasticity indicates responsiveness; elastic means high responsiveness, inelastic means low responsiveness.
