Elasticity of Demand • I f your boss increases your pay from $6 per hour to $7 per hour, how much is your raise as a percent? • Difference between the 2 #’s Divided by the original # x 100 1/6 x100 = 16.6% (not bad) Elasticity = % change in QD % change in price An elasticity greater than 1 = elastic An elasticity less than 1 = inelastic An elasticity equal to 1 = unit elastic
Example A car wash raises its price from $10 to $11. As a result, the number of daily customers falls from 60 to 48. What is this service’s elasticity? % change in QD = 60-48 60 x100 = 20% % change in price = 1/10 x100 = 10% 20/10 = 2 (the service is elastic)
