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.
Elasticity The price elasticity of demand measures the sensitivity of the quantity demanded to changes in the price. Demand is inelastic if it does not respond much to price changes, and elastic if demand changes a lot when the price changes. â¢ Necessities tend to have inelastic demand. â¢ Luxuries tend to have elastic demand.
