Astro Computers makes onboard vehicle control computers for the Tesla. The production department has gathered data on the costs of several yearly production levels and asked you to help interpret these for them.  1. The data for Astro appear in the graph below. The COO asks what production level he should set for the coming year, if Astro operates in a perfectly competitive market. (the graph is in the picture) 2. Is Astro earning “excess profit” (explain what that means if you think they are) and how other firms will react when they see Astro’s performance? 3. The production department has also done a bit of research on other firms operating in the market for onboard control computers. The graph below shows the relative sizes and cost structures of the four largest firms in the market (Data, Astro, Consolidated and BCS); these four firms combined account for 35% of business in the market for onboard control computers.  There are over fifteen firms that supply onboard control computers…

In Problem 5, the market demand decreases and the demand schedule becomes: If firms have the same costs set out in Problem 5, what is the market price and the firm’s economic profit or loss in the short run? Problem 5 The market for paper is perfectly competitive and 1,000 firms produce paper. The table sets out the market demand schedule for paper. The table in the next column sets out the costs of each producer of paper. Calculate the market price, the market output, the quantity produced by each firm, and the firm’s economic profit or loss.

Answer Question 6

7. You are economic consultant for Jack, who farms raw cotton in a perfectly competitive market. One day he gives you the following data at his present level of production: Output = 2000 pounds, market price = $5.00, total cost =$8000, fixed cost=$2000, marginal cost=$5. The minimum of AVC occurs at {1000 pounds at $2} and the minimum of ATC at {1500 pounds at $3.5}. Please help Jack with the following questions based on the above figures: a. Draw a graph for the raw cotton market and a graph for Jack’s farm current situation that includes MC, ATC, and AVC, labeling all relevant points on axes with numerical values. Is Jack maximizing the profit (minimizing the loss)? Why or why not? Label the total profit/loss area. b. Suppose more farmers enter the raw cotton market until the market price is $3.00 per pound. On the same graphs, show the effect of this change in the market place. Would you like to suggest Jack leaving the market in the short run? Explain your answe
