Cartel A large share of the world supply of diamonds comes from Russia and South Africa. Suppose that the marginal cost of mining diamonds is constant at $3,000 per diamond, and the demand for diamonds is described by the following schedule: Price Quantity (Dollars) (Diamonds) 8,000 3,000 7,000 4,000 6,000 5,000 5,000 6,000 4,000 7,000 3,000 8,000 2,000 9,000 1,000 10,000 1. If there were many suppliers of diamonds, the price would beper diamond and the quantity sold would bediamonds.
2. If there were only one supplier of diamonds, the price would beper diamond and the quantity sold would bediamonds. Suppose Russia and South Africa form a cartel.
3. In this case, the price would beper diamond and the total quantity sold would be ??? diamonds. If the countries split the market evenly, South Africa would produce ??? diamonds and earn a profit of $___???.
4. If South Africa increased its production by 1,000 diamonds while Russia stuck to the cartel agreement, South Africa's profit would DECREASE OR INCREASE to $???.
5. Why are cartel agreements often not successful? CHOOSE ONE
One party has an incentive to cheat to make more profit.
