- PROBLEM (5) In a dominant firm market with demand Q = 30 − p, the dominant firm has MC(Q) = 2Q (that is, with TC(Q) = Q^2) and the fringe is composed of 5 identical firms, each with MC(Q) = 10Q (that is, with TC(Q) = 5Q^2). (a) Calculate the market price in the dominant firm model. Calculate the quantity produced by the fringe. (b) Now assume that the 5 fringe firms form a “union”, and act as 5 “plants” of the union firm and this union firm competes as one single firm against the dominant firm in quantities, as in Cournot competition. What is the Cournot-Nash equilibrium price and quantity in this market organization? (c) Now, the dominant firm convinces the “union” not to compete with it but instead collude (to maximize the sum of profits) to form a cartel. What is the market price and quantity? (d) Back to the problem description.

Firm 1, Firm 2 and Firm 3 are the only competitors in a market for a good. The price in the market is given by the inverse demand equation P=10 (Q1+Q2+Q3) where Q, is the output of Firm i (i=1,2,3). Firm 1's total cost function is C₁ = 4Q₁+1, Firm 2's total cost function is C₂ = 2Q2 +3, and Firm 3's total cost function is C3 = 3Q3 + 2. Each firm wants to maximize its profits and they simultaneously choose their quantities. Determine a Nash equilibrium in this market.
- Two firms face the same inverse demand curve: P= 370– q, – 92 . Both firms have the same constant marginal cost: MC = 10. (a) %3D if both firms choose their output levels simultaneously, how much profits and consumer surplus will be earned in equilibrium? (b) Firm 1 is offered the following deal: by paying Z it can either (i) acquire a new technology that lowers its marginal cost to zero or (ii) have to opportunity to produce output before firm 2. Which option would it take and what is the maximum Z it would be willing to pay?Consider an industry with N firms that compete by setting the quantities of an identical product simultaneously. The resulting market price is given by: p = 1000 − 4Q. The total cost function of each firm is C(qi) = 50 + 20qi . (a) Derive the output reaction of firm i to the belief that its rivals are jointly producing a total output of Q-i . Assuming that every firm produces the same quantity in equilibrium, use your answer to compute that quantity. (b) Suppose firms would enter (exit) this industry if the existing firms were making a profit (loss). Write down a mathematical equation, the solution to which would give you the equilibrium number of firms in this industry. You don’t have to solve this equation.Here is a market with three firms: 1, 2, and 3. The demand curve is P=100-Q. There is no fixed cost but the marginal cost 10 for all firms. Firm 1 is a leader firm so that it decides the quantity Q1 first. Then two firms respectively decide their quantities Q2 and Q3 simultaneously. 1) At an equilibrium (SPE), Q1 is Q2=Q3= 2) At the equilibrium, (the market quantity) Q= and (the market price) P= 3) The profit of firm 1 is while the profit of firm 2 and 3 respectively is
- Assume the inverse demand function in a market is given by P(Q) = 500 - Q where Q is the total industry output, that is the sum of the output of all firms in the market. There are two firms (indexed by i = 1,2) who both have a cost of producing the good given by c(qi) = 10 * qi The two firms are competing in the Cournot manner, that is they choose their quantities simultaneously in order to maximize profits.Economics: Industrial Economics Question: In a market that operates under quantity competition there are 2 firms (Cournot duopoly). The inverse demand function is P = A - B Q. The cost structure of firm 1 is given by C1(q1) = F1 + c1 q1 and that of firm 2 is given by C2(q2) = F2 + c2 q2. Prior to competing, the two firms can engage in research at levels (x1, x2) respectively in order to lower their marginal costs. As a result, marginal costs are c1 = c - x1 - β2x2 and c2= C - x2 - β1 X1. where β1 = β2 > ½. Finally, the research costs are F1 = a1 (x1)^2 /2 and F2 = a2 (x2)^2 /2, where a1 > 0 and a2> 0. 1. The Nash Equilibrium research levels are Choices: A. Higher than the cooperative research levels for both firms. B. Higher than cooperative research levels for firm 1 but lower for... C. Lower than the cooperative research levels for both firms. D. Higher than cooperative research levels for firm 2 but lower for... 2. An increase in the value of a2 would Choices: A.…Since you know all about perfect competition, monopoly, and oligopoly, we can find out how various types of firms might feel about uncertainty concerning the prices of its factors of production and output. Consider a profit-maximizing firm that produces a single good from several factors. The firm is characterized by a production function y = f(x1, ... , Xn), where y is the level of output obtainable from factor inputs x1, ... , Xn. We will use p to denote the price of the output good, and Wi to denote the price of factor input i. When there is uncertainty a priori about these prices, the firm is allowed to choose its production plan after any uncertainty in prices resolves. (c) Finally, consider this question in the context of a von Stackelberg duopoly. Two firms produce an undifferentiated commodity for which demand is given by P = A - X, where P is price and X is total supply. Demand-is unchanging. Each firm has production technology with a fixed cost F for producing anything at…
- Consider a market of 6 firms that compete through production. Demand is given as P = 220 – 2Q. Each firm has a marginal cost of $20. a. What will be the equilibrium firm quantities, market price, and firm profits? b. Suppose two firms merge in this market to become a leader. What will be the new equilibrium firm quantities, market price, and firm profits? Was it profitable for the firms to merge into a leader? Note that n = 5 after the merger. c. Suppose another two firms merge to form a second leader in the market. What will be the new equilibrium firm quantities, market price, and firm profits? Was it profitable for the followers to merge into a co-leader? Note that n = 4 and L = 2 after the merger:Q. Three firms operate in a market with a Demand function p = 169 - 2Q. All three firms have identical Cost functions: TC = 1200 - 95q + 2q2.i) Given that the firms are able to collude, what is the equilibrium market price and output?ii) If all of the firms cheat and each increases output by two units, what would be the new equilibrium price and the impact on an individual firm’s profits?Consider a market with the demand curve Q(P) = 3700– 100P. Two companies compete in Bertrand setting, where the first company has a marginal cost of $10 and a capacity of 100 units, and the second firm has a marginal cost of $20 and a capacity of 1000 units. Assume that fixed costs are zero. a) Show that both firms will sell in this market at a price above $20. b) Assume that the first firm is capacity constrained. From the perspective of the second firm, find the quantity sold in the market and the price set by the second firm. c) Now, using the result from the previous part, from the perspective of the first firm, find the quantity sold in the market and the respective price set by the first firm.
