- (5) For each situation, solve for the Bertrand-Nash Equilibrium (differentiated Product). 5a) Suppose Sarah's constant marginal cost is $5 but Joe's is $8 Recall that in a Bertrand model with differentiated product, each supplier faces his/her own demand: Qjoe = 100 – 10 Pjoe + 5 Psarah Qsarah = 100 – 10 Psarah + 5 Pjoe 5b) Suppose Joe and Sarah have the same cost functions as earlier (constant MC of $5) but asymmetric demand functions Qjoe = 100 – 10 Pjoe + 5 Psarah Qsarah = 160 - 10 Psarah + 5 Pjoethe set of Fationalizable strategies will be the same for party R.) Explain your reasoning. ve Intel and AMD, the primary producers of computer central processing units (CPUS), compete with one another in the mid-range chip category (among other categories). Assume that global demand for mid-range chips depends on the quantity that the two firms make, so that the price (in dollars) for mid-range chips is given by P = 210 – Q, where Q = qin- || GAMD and where the quantities are measured in millions. Each mid- + 9AMD tel range chip costs Intel $60 to produce. AMD's production process is more streamlined; each chip costs them only $48 to produce. (a) Write the profit function for each firm in terms of qintel and qAMD- Find each firm's best-response rule. (b) Find the Nash equilibrium price, quantity, and profit for each firm. (c) (Optional) Suppose Intel acquires AMD, so that it now has two sep- arate divisions with two different production costs. The merged firm wishes to maximize total…1. The market (inverse) demand function for a homogeneous good is P(Q) = 10 - Q. There are two firms: firm 1 has a constant marginal cost of 2 for producing each unit of the good, and firm 2 has a constant marginal cost of 1. The two firms compete by setting their quantities of production, and the price of the good is determined by the market demand function given the total quantity. a. Calculate the Nash equilibrium in this game and the corresponding market price when firms simultaneously choose quantities. b. Now suppose firml moves earlier than firm 2 and firm 2 observes firm 1 quantity choice before choosing its quantity find optimal choices of firm 1 and firm 2.
- There are two firms in the market (duopoly). These two firms are competingsimultaneously. The first firm chooses its output level (x) by predicting the second firm’soutput (y). Let c denote the total cost function c(x) = x and c(y) = y. Also, let’s assumethat the inverse demand function is p(Y) = 7 - Y where Y = x + y. (1) Obtain the reactionfunction of the first firm. (2) Find the equilibrium (output and profit of each firm) whentwo firms simultaneously competeSuppose OPEC has only two producers, Saudi Arabia and Nigeria, Saudi Arabia has far more oil reserves and is the lower-cost producer compared to Nigeria. The payoff matrix in the table to the right shows the profits earned per day by each country. "Low output" corresponds to producing the OPEC assigned quota and "high output" corresponds to producing the maximum capacity beyond the assigned quota Which of the following statements is true? OA. The Nash equilibrium is a cooperative equilibrium. OB. The Nash equilibrium is a noncooperative, dominant strategy equilibrium OC. The Nash equilibrium is a collusive equilibrium. D. There is no Nash equilibrium in this game because each party. pursues its dominant strategy. Low output Nigeria High output Low output Nigeria earns $20 million Saudi Arabia Nigeria earns $30 million Saudi Arabia earns $100 million Saudi Arabia earns $80 million High output Nigeria earns $12 million Saudi Arabia earns $75 million Nigeria earns $20 million Saudi Arabia…A study of ethanol as a transportation fuel reveals that the competitive equilibrium is expected to be at a price of $4 per gallon and a consumption rate of 100 million gallons/day. For a production rate of 10 million gallons/day, the marginal cost is found to be $1 per gallon. Also, a a price of $10 per gallon the demand is 10 million gallons/day. Answer the following questions for this system. 1. Determine the equations for the demand and marginal cost lines. 2. Calculate the consumer and producer surplus for the market equilibrium. 3. It was discovered later that the above information ignored a government subsidy of 50 cents per gallon. How will the demand and marginal cost lines, and the competitive equilibrium, change if this subsidy is removed?

The producer of manure produces M pounds of manure daily and earns profits of 156M - M². The bakery sells C' cakes daily, and it earns profits of 312C-C²-MC (the strong smell of manure drives away the appetite of many would-be customers of the bakery). In a competitive equilibrium solution, where each business seeks to maximize profits, a total of if be sold daily. From a social point of view, the producer of manure should not produce at all. Choose one: A. true B. false pounds of manure willTwo firms produce identical products at zero cost, and theycompete by setting prices. If each firm charges a low price,then both firms earn profits of zero. If each firm charges ahigh price, then each firm earns profits of £30. If one firmcharges a high price and the other firm charges a low price,the firm that charges the lower price earns profits of £50, andthe firm charging the higher price earns profits of zero.

In Section 1.2.B, we analyzed the Bertrand duopoly model with differentiated products. The case of homogeneous productsusiness EconomicsQ&A LibraryTwo firms A and B produce an identical product (Note: Industry Output = Q). The firms have to decide how much output qA and qB (Note: qA = Firm A Output; qB = Firm B Output) they must produce since they are the only two firms in the industry that manufacture this product. Their marginal cost (MC) is equal to their average cost (AC) and it is constant at MC = AC = X, for both firms. Market demand is given as Q = Y – 2P (where P = price and Q = quantity). Select any value for X between [21 – 69] and any value for Y between [501 – 999].
