A large percentage of the world supply of diamonds comes from Russia and South Africa. Suppose that the marginal cost of mining diamonds is constant at $1,000. per diamond, and the demand for diamonds is described by the following schedule

            Price, $                        Quantity, diamonds

            10,000                                     3,000

            9,000                                      4,000

            8,000                                      5,000

            7,000                                      6,000

            6,000                                      7,000

            5,000                                      8,000

            4,000                                      9,000

            3,000                                      10,000

            2,000                                      11,000

            1,000                                      12,000

If Russia and South Africa formed a profit maximizing cartel, what would be the price and quantity? If the countries split the market evenly, what would be South Africa’s production and profit? What would happen to South Africa’s profit if it increased its production by 1,000 while Russia stuck to the cartel agreement? What would happen to Russia’s profit?
