- Q2. Consider a two-firms Cournot model with constant returns to scale. Assume also that the inverse demand function is P = 100 – 2Q, with marginal cost equal to 20for both firms, where Q = q1 + q2 . b) How do equilibrium outputs and profits vary when firm1’s cost changes. Draw a picture of this outcome.Please no written by hand solution Considerthe following problem. There are five firms producing a homogenous good and competing in quantities simultaneously. The demand function for this good is given by D(p) = 100−p, where p denotes price. The marginal cost is the same for all firms and equals 40 Answer the following questions. (a) Compute the equilibrium quantities and profits of each firm. (b) Now suppose that two of these firms (say firms 1 and 2) want to merge. (The remaining firms stay unchanged.) Merging, however, is costly. To merge, each merging firm has to pay a fixed cost F. Determine the highest fixed cost F that the two firms would be willing to pay in order to proceed with the merger.In the Stackelberg model, the firm that sets output first has an advantage. Explain why using your own words.
- 5. N - Σ Consider a Cournot model in which N firms compete with each other by setting quantities. The market inverse demand function is P = a i=1 qi, where a > 0 and q; is the quantity of firm i. Firm i's cost function is quadratic: q, where c₂ > 0. (a) Suppose N 2. Find the Nash equilibrium. Show which firm produces more in the equilibrium and explain your result. (b) = Suppose N≥ 2 and ci = c for all i. Find the Nash equilibrium. Show whether the firms produce more or less than the constant marginal cost case where the cost function is cqi, with a>c>0.1) The two firms in an industry, A and B, use a constant returns to scale technology, so face marginal cost c. Market demand conditions are described by the relationship p + p₁x po = 0, where po and p₁ are (constant) parameters, x is the industry output, and p is the market price. Write a report in which you a) Set out the assumptions which underlie the Cournot, and Bertrand, models of competition. b) Demonstrate that in Cournot competition, firms produce less than in Bertrand competition, so that the market price is higher in Cournot competition, and firms make greater profits. c) Explain how we can adapt the Cournot model of competition to set up the Stackelberg model (you should assume that firm A acts as the quantity leader). Define the concept of subgame perfection, and apply that to derive the subgame perfect equilibrium in the Stackelberg model, demonstrating how firm A benefits from being the quantity leader.Economics Bidding for Bookstore Licenses. Paige initially has the only license to operate a bookstore in Bookville. She charges a price of $13 per book, has an average cost of $3 per book, and sells 1,501 books per year. When Paige's license expires, the city decides to auction two bookstore licenses to the highest bidders. Suppose the relevant variables (price, average cost, and output per firm) take on only integer valueslong dash—no fraction or decimals. a. Suppose Paige is optimistic and imagines the best possible outcome with a two-firm market. What is the maximum amount she is willing to pay for one of the two licenses? $ nothing (Hint: How will the relevant variables change? What is the smallest possible change in their values?) b. Suppose Paige is pessimistic and imagines the worst possible outcome with a two-firm market. What is the maximum amount she is willing to pay for one of the two licenses? $ nothing (Enter your response as an integer.)
- Consider a Cournot Duopoly model. The inverse demand for their products is given byP = 200 − 6Q, where Q is the total quantity supplied in the market (that is, Q = Q1 + Q2).

Just help with c and d here pleasePlease solve D and E part only. Thankyou. Consider three firms, each with cost function C(qi)=4qi, currently competing Cournot. Market demand is P = 20 – Q. a. a. Find the quantities, price, and profits of each firm in equilibrium. b. Imagine firms1 and 2 merged to become one, so after the merger there are now two firms left in the market, firm 1&2 and firm 3. Assume there are no cost efficiencies expected and assume that the two firms play Cournot as before. Find the quantities, price, and profits of each firm in equilibrium c. Was it profitable for firms 1 and 2 to merge in the first place? d. Continuing with b., imagine that firms did not play Cournot after the merger, but rather that the merged firm 1&2 became a Stackelberg leader after the merger and firm 3 became the Stackelberg follower.

In 2056, there are two mining firms operating on the moon, extracting Helium 3. Once both firms have entered the market, they compete a la Cournot. The market inverse demand function is given by P(Q) = 8 - Q. Assume that both firms have the total cost functions C(q) =2+2q. Let the star superscript* denote equilibrium quantities/prices/profits.

- 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 2.12. Two firms with differentiated products are competing in price. Firm A and B face the following demand curves: QA = 90 – 2PĄ + Pg and QB = 140 – 2Pg + PA respectively. Assume production is costless. a. Give equations for and graph each firm's reaction curve. b. If both firms set their prices at the same time, what is the Nash equilibrium price, quantity, and profit for each firm? c. Suppose A sets its price first and then B responds. What price and quantity does each firm set now? Is it advantageous to move first? d. Compare the profits from part b and c. Which firm benefits more from the sequential price choosing?1. Two firms (A and B) play a competition game (i.e. Cournot) in which they can choose any Qi from 0 to ¥. The firms have the same cost functions C(Qi) = 10Qi + 0.5Qi2, and thus MCi = 10 + Qi. They face a market demand curve of P = 220 – (QA + QB). a. Assume firm A chooses quantity first. Frim B observes this choice and then chooses its own quantity. What is Frim B's profit as a function of QA and QB? b. Firm B has MRB = 220 – 2QB – QA. What is firm B’s best response to an arbitrary QA selected by firm A? c. Given that firm A expects firm B’s best response, what is firm A’s profit as a function of QA? (Hint: the only unknown variable in the profit function should be QA) d. Firm A has MRA = 150 – 4QA/3. What are the equilibrium QA and QB selected in this game? e. What is the equilibrium price, and how much profit does each firm collect?
