Green Valley Water and Granite Slope Water are sellers of spring water in the Republic of Bogritania. Like mineral water sellers in many simple examples, they have no costs so their payoffs are the revenues they obtain from selling water. The price of mineral water in Bogritania is 1,000-qv-qs , where qv is the quantity sold by Green Valley and qs is the quantity sold by Granite Slope. As a result: Proposition A: Each firm's best response is to sell...
