Prices of gasoline change rapidly if something interrupts the oil supply. How responsive do you believe the customers will be to price changes as a result of supply disruptions? Why? Support your answer using the determinants of the price elasticity of demand. Considering the concepts of the price elasticity of demand, why do you think that gas stations rarely offer promos or discounts? What will happen to their total revenue if they increase their price? And how about if they decrease their price?

1. As a transit planner for the city of Miami, you must predict how many people ride the Miami Metrorail and how much money is generated from train fares. According to a recent study, the short-run elasticity of demand for Metrorail is 0.62 and the long- run elasticity is 1.59. The current ridership is 50,000 people per day. Suppose the city commission decides to increase fares by 10%. Predict the changes in train ridership over a one-month period and a five-year period. ANS: b. Over the one-month period, will total revenue increase or decrease? What will happen in the five-year period? ANS

Each scenario gives some information about price elasticity of demand. For each, calculate the missing data, and determine if the price change under consideration will increase, decrease, or not change the firm's total revenue. Honest Abe's Used Cars estimates the price elasticity of demand for their cars to be -4.1. Last month, Abe tried a new marketing scheme which decreased the number of cars sold by 87%. Abe must have his prices by -27.87 Abe's total revenue by increased and total revenue to increased. At Webs-R-Us, a website design company, the new manager has decided to increase the price of Webs-R-Us services by 15%. She estimates that Webs-R-Us has a price elasticity of demand at -0.30. The manager expects the number of websites designed to decrease increase. %. e %
