PC Connection and CDW are two online retailers that compete in an Internet market for digital cameras. While the products they sell are similar, the firms attempt to differentiate themselves through their service policies. Over the last couple of months, PC Connection has matched CDW’s price cuts but has not matched its price increases. Suppose that when PC Connection matches CDW’s price changes, the inverse demand curve for CDW’s cameras is given by P = 1,500 − 3Q. When it does not match price changes, CDW’s inverse demand curve is P = 900 − 0.50Q. Based on this information, determine CDW’s inverse demand and marginal revenue functions over the last couple of months. Over what range will changes in marginal cost have no effect on CDW’s profit-maximizing level of output?
You are the manager of a golf course. For simplicity assume that you only have two potential customers – a high demand customer whose inverse demand for golf services is given by P = 10 – 0.5Q and a low demand customer whose inverse demand for golf services is given by P = 8 – 0.5Q. Suppose the marginal cost to the golf course of each round of golf is zero.Suppose you have to charge both players the same two-part pricing strategy. Which of the following pricing strategies will yield the highest profit for you? A. Charge a fixed fee of €100 and a per unit fee of zero B. Charge a fixed fee of €64 and a per unit fee of zero C. Charge a fixed fee of €64 and a per unit fee of €4 D. Charge a fixed fee of €128 and a fixed fee of zero.
Kafue Water and Sewerage Company and Lusaka Water and Sewerage Company are duopolistic firms operating under the Cournot model. The two companies are both supplying Water to Chilanga District whose total demand is given by a linear demand function Q = 720 – 2P = 3q1 + 3q2, where q1 represents water output by Kafue Water, and q2 is water output by Lusaka Water and Sewerage Company. Assume that: Each firm has no production costs Each firm has to decide how much water to supply to the market Given the above information, determine The profit-maximizing output, price, and level of profit for the two companies. The individual level of outputs q1 and q2, as well as the revenue for which the two companies are maximizing profits. Interpret your results in (i) and (ii)
American Airlines and Braniff Airways are the two airlines operating flights from your region. Suppose that each company can charge either a high price for tickets or a low price. First, American Airlines will choose the price level. Following this, Braniff Airways will observe its competitor’s decision and choose the price level for its tickets. If both of the companies choose High, they earn $25,000 each. If they both choose Low, they earn $18,000 each. If the companies choose different levels of prices, the one choosing the high price will earn $15,000 and the one choosing Low will earn $30,000. a) Draw the game three. b) Solve the game by using backwards induction. c) If Braniff Airlines makes a promise to choose High if American Airlines chooses High, should American Airlines trust this promise? Explain.
suppose there are two firms that compete in prices, say firms 1 and 2, but that the firms produce differentiated products. Suppose that the demand for firm 1 is q1(p1,p2)=10-2p1+p2 and the demand for firm 2 is q2(p2,p1)=10-2p2+p1. Also, assume that firm 1 has a constant marginal cost of c1 = 2 and firm 2 has a constant marginal cost of c2 = 3. i. Solve for the Bertrand equilibrium in prices. ii. Now, suppose firms 1 and 2 merge and firm 1 will operate both firms and they will split the resulting profits equally. Will both firms agree to this merger or do they prefer the Bertrand outcome?
Suppose that two Japanese companies, Hitachi and Toshiba, are the sole producers (i.e., duopolists) of a microprocessor chip used in a number of different brands of personal computers. Assume that total demand for the chips is fixed and that each firm charges the same price for the chips. Each firm’s market share and profits are a function of the magnitude of the promotional campaign used to promote its version of the chip. Also assume that only two strategies are available to each firm: a limited promotional campaign (budget) and an extensive promotional campaign (budget). If the two firms engage in a limited promotional campaign, each firm will earn a quarterly profit of $14 million. If the two firms undertake an extensive promotional campaign, each firm will earn a quarterly profit of $11 million. With this strategy combination, market share and total sales will be the same as for a limited promotional campaign, but promotional costs will be higher and hence profits will be lower.…
Microsoft and a smaller rival often have to select from one of two competing technologies, A and B. The rival always prefers to select the same technology as Microsoft (because compatibility is important), while Microsoft always wants to select a different technology from its rival. If the two companies select different technologies, Microsoft's payoff is 6 units of utility, while the small rival suffers a loss of utility of 2. If the two companies select the same technology, Microsoft suffers a loss of utility of 2 while the rival gains 2 units of utility. Using the given information, fill in the payoffs for each cell in the matrix, assuming that each company chooses its technology simultaneously. Microsoft Technology A Technology B Rival Technology A Rival: , Microsoft Rival: , Microsoft Technology B Rival: , Microsoft Rival: , Microsoft True or False: There is no equilibrium in pure strategies.

If the two companies select the same technology, Microsoft suffers a loss of utility of 1 while the rival gains 1 units of utility.
There are two competing companies: Starbucks and Coffee Bean. Both companies want to determine whether they should launch a new advertising campaign for their coffee shops. If both companies start advertising, Starbucks will attract 4 new customers, while Coffee Bean will attract 3 new customers. However, if both companies decide not to advertise, Starbucks will attract only 3 new customers and 2 new customers for Coffee Bean. If only Starbucks decides to advertise, it will attract 5 new customers, while Coffee Bean will attract only 1 new customer for not advertising. While if only Coffee Bean decides to advertise, it will attract 5 new customers, and Starbucks will only attract 2 new customers for not advertising. What is the optimal strategy for Coffee Bean if Starbucks chooses to Advertise? Please explain in detail In relation to that, if Coffee Bean chooses to Advertise, the Payoff is __. In relation to that, if Coffee Bean chooses Not to Advertise, the Payoff is __. What is…
Consider two firms that compete according to the Cournot model. Inverse demand is P (Q) = 16 − Q. Their cost functions are C (q1) = 2q1 and C (q2) = 6q2 (a) Solve for Nash equilibrium quantities of each firm (b) Suppose firm 2 becomes more inefficient and its cost function changes to C (q2) = xq2 where x > 6. How large must x be to cause firm 2 to not want to produce anything in equilibrium?
Three products compete in a market and their demand and supply functions are qd1 = 44-2p1+p2+p3 qs1 = -10+3p1 qd2 = 25+ p1 –p2 +3p3 qs2 = -15+5p2 qd3 = 40 +2p1+p2 -3p3 qs3 = -18+2p3 where p1, p2, and p3 are the prices. Determine the prices and quantities which result in equilibrium in each market using Cramer’s rule.
Two airlines, Dragon Airline and Phoenix Airline, provide direct flight service to a city and tend to compete for the same group of travellers. They are contemplating changing their airfares to earn more profit. If both airlines raise their airfares, Dragon Airline will earn $800m while Phoenix Airline will earn $400m in profit. If both airlines reduce their airfares, Dragon Airline will earn $650m while Phoenix Airline will earn $550m in profit. If Dragon Airline raises its airfare while Phoenix Airline reduces its airfare, Dragon Airline will earn $200m while Phoenix Airline will earn $350m in profit. If Dragon Airline reduces its airfare while Phoenix Airline raises its airfare, Dragon Airline will earn $300m while Phoenix Airline will earn $250m in profit. Construct the payoff matrix in terms of profit for the two pricing strategies. Apply a game theory concept and solve this game using the Nash equilibrium method. Explain how you derive your answers and also whether this game is a…
