Problem 1: Consider the following Bertrand duopoly: two firms (A and B) are operating in a market where they produce identical products and compete on price. Assume that the market demand can be written as ? = 50 − ?. Assume that neither firm is capacity constrained so that either firm can satisfy the market demand at any price. Suppose further that the profit function for each firm can be written as ? = ?? − ?? = (? − ?)? where V is the constant marginal cost which we will assume is 2. What will be the price in the market? What will be the profits of each firm?

B) Consider the following change to the Bertrand duopoly described in the previous problem: suppose that the marginal costs of each firm are not the same but instead ?A = 4 and ?B = 2. What will be the price in the market? What will be the profits of each firm?

Two identical firms compete in a Bertrand duopoly. The firms produce identical products at the same constant marginal cost of MC = $10. There are 2000 identical consumers, each with the same reservation price of $30 for a single unit of the product (and $0 for any additional units). Under all of the standard assumptions made for the Bertrand model, the equilibrium prices would be Group of answer choices $10 for both firms $30 for both firms $50 for both...

Consider the following variant of theBertrand Model of Duopoly. Suppose there are two firms producing the same good and they simultaneously set prices for their product. If firm i sets a price piand firm j sets a price pj, the total quantity demanded for firm i’s product is given by:qi= 10 –pi+ ½ pjEach firm produces exactly the qidemanded by the market. Bothfirms have the same marginal cost of production: c=4. For example, if a firm produces 5 units it...

Consider the following asymmetric-information model of Bertrand duopoly with differentiated products. Demand for firm i is qi(pi,pj) = a−pi + bi ·pj. Costs are zero for both firms. The sensitivity of firm i’s demand to firm j’s price is either high or low. That is, bi is either bH or bL, where bH > bL > 0. For each firm, bi = bH with probability θ and bi = bL with probability 1−θ, independent of the realization of bj. Each...

Assume that you observe two firms operating in a Bertrand oligopoly. The inverse demand function for the market is P = 200 – 2Q and each firm has the same cost function of C(Q) = 20Q. What is the level of production for each firm, market price, and profit of each firm? What would happen if both firms merge to form a single monopoly with a cost function of C(Q) = 20Q?

Problem 2. Consider a duopoly with identical firms with no fixed cost and marginal cost of c. Let the inverse demand curve for the industry be p(Y ) = A − bY , where Y is the total industry output. Let y1 and y2 be the output of each firm. Assume that the firms in the industry each choose quantity, and then let the market determine the price they will receive. (a) Compute the total market output, the price, the...

Suppose two firms, "A" and "B," form a duopoly in the market for a special type of computer chip. Each firm has a constant marginal cost of $2. The daily market demand for this chip is given by the following equation: P = 8 – 0.005 Q = 8 – 0.005 (qA+qB). a. Find an expression for firm #A's revenue, as a function of its own quantity and firm B’s quantity: RevA(qA,qB). [Hint: By definition, RevA = P qA. Here,...
