486 PART 3 • Market Structure and Competitive Strategy
*14. A lemon-growing cartel consists of four orchards.
Their total cost functions are
TC 1 = 20 + 5Q 21
TC 2 = 25 + 3Q 22
TC 3 = 15 + 4Q 23
TC 4 = 20 + 6Q 24
TC is in hundreds of dollars, and Q is in cartons per
month picked and shipped.
a. Tabulate total, average, and marginal costs for each
firm for output levels between 1 and 5 cartons per
month (i.e., for 1, 2, 3, 4, and 5 cartons).
b. If the cartel decided to ship 10 cartons per month
and set a price of $25 per carton, how should output be allocated among the firms?
c. At this shipping level, which firm has the most
incentive to cheat? Does any firm not have an incentive to cheat?
