- ASAP PLZ You are the manager of Taurus Technologies, and your sole competitor is Spyder Technologies. The two firms’ products are viewed as identical by most consumers. The relevant cost functions are C(Qi) = 2Qi, and the inverse market demand curve for this unique product is given by P = 650 −3 Q. Currently, you and your rival simultaneously (but independently) make production decisions, and the price you fetch for the product depends on the total amount produced by each firm. However, by making an unrecoverable fixed investment of $1,800, Taurus Technologies can bring its product to market before Spyder finalizes production plans. (Assume Taurus Technologies is the leader in this scenario.)What are your profits if you do not make the investment? $ ____What are your profits if you do make the investment?Instructions: Do not include the investment of $1,800 as part of your profit calculation. $ ____ Should you invest the $1,800? multiple choice Yes - the benefits of establishing…Consider an imperfectly competitive service provider, Muscat Automotive Repair Services (MARS), whose total cost of production is C = 30Q +0. 165Q2. Also, MARS faces two different market segments, A and B, whose demands can be linearly expressed as QA = 240 − PA and QB = 120 − 0.5PB . (Hint: the marginal cost is the slope of the total cost function). 4. If MARS decides to segment the market in accordance with the demands of groups A and B, find the profit-maximizing prices and quantities (PA, QA) and (PB, QB).5. What is the value of the consumer surplus for each group A and B, under this segmentation strategy?6. Draw the situation described in (4) and (5) above, clearly showing each group’s profitmaximizing price and quantity, and the areas that correspond to their consumer surpluses.7. Verify the inverse elasticity rule under each of the scenarios described (1) and (4) above.Please no written by hand solutions 2. Mr Gieves and Mr Hawkes produce items of clothing. The market demand for clothes is y = 13-p with y = y1+y2 and p denoting the market price of clothes. Mr Gieves and Mr Hawkes compete by simultaneously choosing the quantity of clothes to send to the market, and their cost functions are C1 (y1) = y₁ and C₂(y2) = y2 respectively. (a) Set up the profit functions, and derive the reaction functions. (b) Find the Cournot equilibrium of the market. Indicate what the market price, individual outputs and profits are.
- Consider a firm facing conventional technology with U-shaped AVC and ATC and MC. The firm wants to maximize profits given an exogenously fixed price of P = $20. Further, suppose the firm correctly determines that its short run profit maximizing output is 1000 given its costs and the exogenously fixed price of $20. Question 1A Using the axes as constructed below, depict marginal revenue and marginal cost curves that would support the conclusion that the optimal short run output is q = 1000. Be sure to label all important values Question 1B Is this a short run equilibrium? Explain Question 2A Reproduce your graph from Question 1, but add an average total cost curve to the picture in such a way that the firm is earning zero profits (π = 0). Upload your graph Question 2B Does your graph in Question 2A depict a short run equilibrium? If so, explain why. If not, explain why not Question 3A Again, reproduce your graph from Question 1. For this question, depict a different ATC curve, one where…Please no written by hand and no emage Two firms compete in a homogeneous product market where the inverse demand function is P = 20 −5Q (quantity is measured in millions). Firm 1 has been in business for one year, while Firm 2 just recently entered the market. Each firm has a legal obligation to pay one year’s rent of $1.6 million regardless of its production decision. Firm 1’s marginal cost is $2, and Firm 2’s marginal cost is $10. The current market price is $15 and was set optimally last year when Firm 1 was the only firm in the market. At present, each firm has a 50 percent share of the market.Determine the current profits of the two firms. Firm 1's profits: $Firm 2's profits: $What would each firm’s current profits be if Firm 1 reduced its price to $10 while Firm 2 continued to charge $15?Firm 1's profits: $Firm 2's profits: $Suppose that, by cutting its price to $10, Firm 1 is able to drive Firm 2 completely out of the market. After Firm 2 exits the market, does Firm 1 have an…The information below applies to a competitive firm that sells its output for $40 per unit. • When the firm produces and sells 150 units of output, its average total cost is $24.50. • When the firm produces and sells 151 units of output, its average total cost is $24.55. Refer to Scenario 14-2 . Let Q represent the quantity of output. Which of the following magnitudes has the same value at Q = 150 and at Q = 151? a. Total revenue b. Average fixed cost c. Total cost d. Average revenue
- Yummy Yummy Popcorn, Inc. sells bags of flavored popcorn in a popular mall. As shop owner and operator, you have observed that weekly popcorn sales are well-described by the demand equation: Q = 1,200 - 800P + 2.0A, where A denotes advertising weekly spending (in dollars). You are currently charging $1.50 per bag of popcorn (for which the marginal cost is $.75) and spending $500 per week on advertising. b) Check whether your current $1.50 price is profit maximizing. If not, determine the store’s optimal quantity and price. c) Should the store consider increasing its advertising spending? Why or why not.

JointJuice produces a prepackaged joint support supplement for relief of joint pain with 180 tablets per bottle and operates in a perfectly competitive market. Basically, all the firms in this competitive market have technologies (production and cost conditions) that are the same as JointJuice’s. Suppose JointJuice’s total cost function is given by the following where q is JointJuice’s quantity of packages per day: C(q) = 250 + 6q + 0.1q^2 The market demand function for the output in this market is given by: Q = 1848 - 2P If there are 20 identical firms in this industry, find the market equilibrium price for the prepackaged supplements.

- A profit maximizing firm produces a single product that it sells in two distinct markets 1 & 2. The demand and cost functions for the firm are given below. Q1 = 21- 0.10P Q2 = 50 - 0.40P TC = 2000 + 10Q where Q = Q1 + Q2Find the equilibrium quantities transacted and the prices charged in each market.Suppose company XYZ produces a differentiated commodity. The company has substantial control over the price of the product. The company’s cost function is estimated to be TC = 200 – 20Q + Q2, where Q is the volume per day. The firm also has the following demand equation P = 60 – 2Q, where P represents the price per unit and Q the volume of daily sales. What level of output should management of XYZ produce? a. 30 b. 10 c. 20 d. 15Firm 1 must decide whether to enter an industry in which firm 2 is an incumbent. To enter this industry, firm 1 must choose to build elther a plant with a small output capacity (S), or large output capacity (L). A plant with small capacity costs $50 to set up; one with large capacity cost $175. In either case, the marginal cost of production is zero. But firm 1 can also opt to stay out (0), in which case it does not incur any type of cost. Firm 2 is able to observe firm 1's decision before deciding whether to expand or not its initial small output capacity operation. Expanding (E) costs firm 2 $76, whereas not expanding (N) incurs no cost for the firm. In either case, the marginal cost of production is also zero. The revenues under the different scenarios are given below. - It only one small firm exists, its revenue is $80, the other earns zero. - if two small firms exist, each earns revenue of $70. - If only one large firm exists, its revenue is $200, the other earns zero. - If…
