9). When price=3 then Quantity demanded=150-5P=150-5(3)=135
Total amount of quantity produced in an industry=135
b) in long run, all firms produces at min of AC. Thus all firms produces only 5 unit
Thus number of firms=135/5=27 firms will operate
firms=27
9. The long-run supply curve of a perfectly competitive firm is given by a horizontal line...
The long-run supply curve for a perfectly competitive, constant-cost industry O is horizontal at minimum ATC. O is upward-sloping. O is horizontal at minimum AVC. O is found by adding up the marginal cost curves for all firms in the industry. As more firms enter the market: O the short-run market demand curve shifts to the left. O the short-run market supply curve shifts to the right. O the short-run market supply curve shifts to the left. O the short-run...
(a) All firms in a perfectly competitive industry face the same long-run average cost curve, AC = 0.05q – 5 + 500/q, and the same long-run marginal cost curve given by MC = 0.1q – 5. The market demand for the product of these firms is QD = 100,000 – 10,000P. i.Calculate the equilibrium price and quantity. ii.Assuming the market is in long-run equilibrium, how many firms will be on the market? (b) Suppose the demand for cotton T-shirts is...
5. Short-run supply and long-run equilibrium Consider the perfectly competitive market for steel. Assume that, regardless of how many firms are in the industry, every firm in the industry is identical and faces the marginal cost (MC), average total cost (ATC), and average variable cost (AVC) curves shown on the following graph. COSTS (Dollars per ton) + MC D AVC 0 10 90 100 20 30 40 50 60 70 80 QUANTITY (Thousands of tons) The following diagram shows the...

Answer just part b ) All firms in a perfectly competitive industry face the same long-run average cost curve, AC = 0.05q – 5 + 500/q, and the same long-run marginal cost curve given by MC = 0.1q – 5. The market demand for the product of these firms is QD = 100,000 – 10,000P. i. Calculate the equilibrium price and quantity. ii. Assuming the market is in long-run equilibrium, how many firms will be on the market? (b) Suppose...
31 In perfectly competitive industries: A. the shont-run market supply curves are positively sloped в. long-rusniustry supply curve,are positively sloped. C. the short-run D. All of the above E. Only B and C are correct market supply curves are more clastic than the long-run industry supply curvers s3. Assame a perfectly-competitive, increasing-cost industry composed of identical firms is initially in long-run equilibrium. Given a decrease in demand, in the short ran: equilbrium price decreases, equilibrium output increases, the output of...
Each firm in a perfectly competitive market has long run average cost represented as AC(q) = 100q- 10+100/q. Long run marginal cost is MC=200q-10. The market demand is Qd = 2150-5P. Find the long run equilibrium output per firm, q*, the long run equilibrium price, P*, and the number of firms in the industry, n*. P = 190; Q = 1200; q =1 , n = 1200
Suppose that the market for laptops is perfectly competitive. These companies are identical with their long-run cost functions for a full day of keyboarding given by: TC(Q) = 6Q3-30Q2+200Q Market Demand is: Qd = 8,000 - 20P a. Find the long-run equilibirum price in this industry b. Use market demand to find the equilibrium total industry output. c. Find the equilibrium number of firms.
Suppose the market for wheat is perfectly competitive. Suppose further the long-run supply curve in this market is increasing. Explain briefly if and how each of the following varies as market quantity increases: i) The number of firms ii) Input prices iii) Long-run profits Suppose firms in a monopoly competitive market produce their profit-maximizing quantity, and their average total cost equals their marginal revenue. Should firm entry or exit in the long run?
