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) 8000 5000 7000 6000 6000 7000 5000 8000 4000 9000 3000 10000 2000 11000 1000 12000 a) If there were many suppliers of diamonds, what would be the price and quantity? b) If there were only one supplier of diamonds, what would be the price and quantity? c) If Russia and South Africa formed a 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? d) Use your answers to part (c) to explain why cartel agreements are often not successful.

Question You are an executive for Super Computer, Inc. (SC), which rents out super computers. SC receives a fixed rental payment per time period in exchange for the right to unlimited computing at a rate of P cents per second. SC has two types of potential customers of equal number—10 businesses and 10 academic institutions. Each business customer has the demand function: Q=14−P, where Q is in millions of seconds per month; each academic institution has the demand: Q=10−P. The marginal cost to SC of additional computing is 2 cents per second, regardless of volume. a. Suppose that you could separate business and academic customers. What rental fee and usage fee would you charge each group? What would be your profits? (Round all answers to the nearest integer) For business users, the rental fee would be$720,000per month and the usage fee is 2 cents per second. For academic institutions, the rental fee would be $320,000 per month and the usage fee is 2 cents per…
Q32 Let's assume we are referring to the Canadian market for Random Access Memory (RAM) storage. If the price of RAM increases: Multiple Choice total revenue for RAM producers will decrease if demand for RAM is price inelastic. the consumer surplus for Canadian consumer will decrease. consumers will buy more because RAM is an inferior good. the consumer surplus of Canadian will increase. total revenue for RAM producers will increase if demand for RAM is price elastic.

Take this hypothetical situation: Suppose that the supply side of the market for for electric energy is comprised of two sellers: Seller 1 and Seller 2. Let P be the price of one unit of electric energy, and Q be the quantity of electric energy. Seller 1 owns a hydropower factory with a constant marginal cost of $3 and can produce a maximum of 10 units of electric energy. In addition, the hydropower plant has a requirement of a minimum of 3 units of electric energy. Seller 2 owns a solar factory to produce electric energy. This factory has a constant marginal cost of $5 and can produce a maximum of 5 units of electric energy. With this given information, please sketch the market supply by aggregating the two individual supplies. Please label the graph clearly for slopes, kinks, intercepts, etc.

Exercise A.9 You are an executive of Super Computer, INC. (SC), which rents supercomputers. SC receives a fixed rent for a period of time in exchange for the right to use unlimited computers equal to P cents per second. SC has two types of potential clients of equal numbers: 10 companies and 10 academic institutions. Each company has the demand function Q = 10 – P, where Q is expressed in millions of seconds per month; each academic institution has the demand Q = 8 – P. The marginal cost to SC of additional computer utilization is 2 cents per second, regardless of volume. a) Suppose you can distinguish companies from academic clients. What rental and usage fee would you charge each group? Calculate the profits you would get? b) Suppose that you cannot separate the two types of customers and that you did not charge a rental fee. What usage quota would maximize your profits? How many benefits would you get?

There are two types of potential users: 100 farmers and 100 ranchers. Each farmer demand is given by Qf = 20 - Pf, and each rancher's demand is given by Qr = 25 - Pr, where Q is in 1000 minutes per month and P is in USD per minutes. The marginal cost is 5 USD per minute. Suppose that you could separate farmers and ranchers. For ranchers, the optimal rental fee is A) 5 B) 200,000 C) 500 D) 0
