  1. Review with your Partners Name the five determinants of Demand. What is a substitute good? What is a complimentary good? Why do we calculate slope? What is the relationship between price and quantity demand? If your slope answer is 5/-25, what does it mean? What way does the demand curve shift if there is a decrease in demand? Name 10 college mascots.

  2. Chapter 4 Changes in Demand

  3. Demand Shifts • Determinants of Demand – factors that shift our demand curve – to the right or to the left • Shift to the right = increase in demand by the consumers • Shift to the left = decrease in demand by the consumers • 5 determinants of demand

  4. Determinants of Demand • Consumer tastes and preferences • Market size • Income • Prices of related goods • Consumer expectations

  5. Substitute Goods • Goods that can be used to replace the purchase of similar goods when prices rise

  6. Complementary Goods • Goods that are commonly used with other goods. • Example – peanut butter and jelly

  7. Elasticity of Demand Chapter 4

  8. Elasticity of Demand • The degree to which changes in a goods price affect the quantity demanded by consumers. • The demand for a product can be either inelastic or elastic.

  9. Elastic Demand • Exists when a small change in a goods price causes a major, opposite change in the quantity demanded. • Not necessary • Available substitute goods • Examples – Food and clothes P d QD

  10. Inelastic Demand • Exists when a change in a goods price has little impact on the quantity demanded. • Necessary good • Few substitute goods available • Insulin for diabetes, • EpiPen for allergies • Gas, toothpaste P d QD

  11. % change in QD %change in P Calculate % change by taking the difference of the two numbers and divide it by the original starting number! Example – if QD changes from 12million to 14million and Price changes from 5 dollars to 3 dollars. 2/12 = .167 = .4175 2/5 .4 Measuring Elasticity

  12. What does your answer mean? • x>1 = elastic • x<1= inelastic • x=1= unit elastic
