  3. Demand Elasticity • Demand Elasticity: a measure of how changes in price causes changes in Quantity Demanded. How will a price change influence a consumer’s decision to buy? • EXAMPLE: Lobster Tails • Usually priced at $12 each • Price lowered to $9 each • How will the price change impact Quantity Demanded? • Will people buy the same amount of lobster or more lobster because of the price change? • Demand Elasticity illustrates how price changes influence consumer behavior!!! 3

  4. Elastic Demand • Elastic Demand : a change in price causes a large change in quantity demanded (how much of a good or service consumers purchase) • EXAMPLE: MacBookAir (Apple laptop) • MacBook Air (Apple laptop) sells for $1,300 • Best Buy will usually sell one MacBookAir a day • Best Buy offers the product for 15% off, reducing the price to $1,105. Best Buy sells three MacBooks before lunch the first day of the sale. 4

  5. Inelastic Demand (NOT elastic) • Inelastic Demand (NOT elastic): a change in price causes LITTLE or NO CHANGE in the quantity demanded • EXAMPLE: Gas Prices • Regular gas is $3.96 per gallon • Prices jump the following week to $4.15 agallon, an increase of 5% • Sales of gasoline at Sunoco remain constant from week 1 to week 2, despite the increase in price. 5
