QUESTION 4.6 Your summer internship is with the strategy department of Chevy Chase Bank (CCB). They are considering changing the fee they charge to non-customers who use their automated teller machines (ATMs). CCB customers can use CCB ATMs without a fee. CCB conducted some market research and have found that when they raise their ATM fee, they actually increase the number of new checking account customers per day-the cross-price elasticity is positive. Non- customers get tired of paying the fee so they become customers. However, as you raise ATM fees you lose non-customer transactions at your ATMs. The non-customer demand for CCB ATM transactions is given by the equation Q = 19,000 - 6,000P. Right now CCB handles 10,000 non- customer ATM transactions per day at a fee of $1.50. a. What is the own-price elasticity for ATM fees charged to non-customers? N At the current ATM fee, should you raise or lower your ATM fees? Why? b. What should your new ATM fee be if your marginal cost of…
