Table 16-4 Imagine a small town in which only two residents, Tony and Jill, own wells that produce safe drinking water. Each week Tony and Jill work together to decide how many gallons of water to pump, to bring the water to town, and to sell it at whatever price the market will bear. To keep things simple, suppose that Tony and Jill can pump as much water as they want without cost so that the marginal cost of water equals zero. The weekly town demand schedule and total revenue schedule for water is shown in the table below.

Table 16-9 Each year the United States considers renewal of Most Favored Nation (MFN) trading status with China. Historically, legislators have made threats of not renewing MFN status because of human rights abuses in China. The non renewal of MFN trading status is likely to involve some retaliatory measures by China. The payoff table below shows the potential economic gains associated with a game in which China may impose trade sanctions against U.S. firms and the United States may not renew MFN status with China. The table contains the dollar value of all trade-flow benefits to the United States and China.
