SmacFone is a major provider of pay-by-the-minute, no contract cellphones that are very popular with ordinary consumers. They are also quite popular with drug dealers, who appreciate the anonymity that such phones provide.
The inverse demand curves for the drug dealers is: p = 0.25 - q /1200, and for the ordinary conumers is: p = 0.15-q / 6000. SmacFone's marginal and average total cost of service is 0.05 dollar per minute.
a. Determine the profit-maximizing price and quantity that SmacFone would like to charge each type of consumer, and the potential profit that SmacFone could generate from each segment.
If SmacFone cannot tell whether a new customer is an ordinary person or a drug dealer, it decides to use second-degree price discrimination to separate consumers. SmacFone sets a Plan A price of 15 cents per minute, but offers a special Plan B price of 10 cents per minute if a customer purchases 300 or more minutes.
b. Determine how much consumer surplus ordinary consumers would receive under Plans A and B. Which plan should ordinary consumers choose if they are trying to maximize their surplus?
c. Determine how much consumer surplus drug dealers would receive under Plans A and B. Which plan should drug dealers choose if they are trying to maximize their surplus?
d. Is the plan SmacFone derived incentive compatible? (In other words, will the plan successfully direct drug dealers to Plan A and ordinary consumers to Plan B?) How much profit will SmacFone generate with this set of plans?
e. SmacFone is considering making some adjustments to their plans. One option is to change Plan B to 11 cents per minute with a 240-minute minimum. Determine whether the new plan selection is incentivecompatible. Why doesn't SmacFone simply raise the price to 11 cents without altering the 300-minute minimum? How much profit will the new set of plans generate for SmacFone?
f. Another option that SmacFone is considering is dropping the price of its ordinary service to 14 cents per minute. Determine whether the new plan selection is incentive compatible. How much profit will the new set of plans generate for SmacFone?
