Elasticity Chapter 6 THIRD EDITION ECONOMICS and MICROECONOMICS Paul Krugman | Robin Wells What is the definition of elasticity? What is the meaning and importance of: price elasticity of demand? income elasticity of demand? Price Elasticity of Demand What is it (in simple language)? It’s how much buyers will respond to a change in price. It’s the percentage change in quantity demanded ÷ the percentage change in price. Elasticity – the concept. The responsiveness of one variable to changes in another. When price rises, what happens . to demand?. Demand falls. BUT!. How much does demand fall?. Elasticity – the concept. Arsens. Jules . Dupuit. . in 1844. Later . Alfred Marshall . developed this concept in his famous work . ‘Principles of Economics'. . . In our daily life, we consume many commodities that are available cheap. Example: salt, match box news papers, etc. The utility from these commodities is so high that we would be prepared to pay higher prices for them than we actually pay. . How would you respond?. If the price of Nikes dropped by 25%, how likely would you be to buy more Nikes?. If the price of a Starbucks lattes increased by 25%, how likely would you be to buy fewer lattes?.
