Isolated Island has two taxi companies, one owned by Ann and the other owned by Zack. Figure 1 shows the market demand curve for taxi rides, D, and the average total cost curve of one of the firms, ATC.
If Ann and Zack form a cartel and produce the same quantity of rides as would be produced in monopoly, what are the quantity of rides, the price of a ride, and the economic profit of Ann and Zack? Would Ann and Zack have an incentive to break the cartel agreement and cut their price? Explain why or why not.
