In a survey of nearly 200 senior marketing managers, 71 percent responded that they found a customer satisfaction metric very useful in managing and monitoring their businesses. Here are the top six reasons why customer satisfaction is so important:
1 When the price elasticity of demand for a good is unit (or unitary) elastic (E d = 1), the percentage change in quantity is equal to that in price, so a change in price will not affect total revenue.2  When the price elasticity of demand for a good is relatively elastic d. When the price elasticity of demand for a good is relatively elastic d. 2  When the price elasticity of demand for a good is perfectly elastic (E d is â â), any increase in the price, no matter how small, will cause demand for the good to drop to zero. 3  Hence, when the price is raised, the total revenue falls to zero.
Supply is elastic if the price elasticity of supply is greater than 1 (es > 1), unit elastic if it is equal to 1 (es = 1), inelastic if it is less than 1 (es < 1), perfectly elastic when a small change in price changes the quantity supplied by an infinite amount (es = Ã¢ËÅ¾) and perfectly inelastic when the quantity supplied is unaffected by a change in price (es = 0).
