Under a perfectly competitive market, given the mentioned assumption, price of the good is supply determined. That is, irrespective of the demand, the price will be equal to the cost of making the good, that is = average cost = marginal cost.
Then what is the role of demand?
Demand determines the output of the good. Since in a perfectly competitive industry, the producers have no control over the price, they adjust to the prevailing demand conditions by varying the output they produce. In case of a negative demand shock, they understand that consumers will purchase less. Since they cannot lower the price of the good they produce, they react to the adverse shock by lowering their produce.
In the diagram below, the producers cut their production from QE to Q'.

C) is greater than long-run average cost. D) is greater than short-run average cost. The industry that produces zangs is in long-run equilibrium. Then the demand for zangs increases permanently. As a result, firms in the industry will ________. Some firms will ________ the industry, and the industry...
2) Suppose we observe a perfectly competitive industry in long-run equilibrium when there is a permanent decrease in demand for the industry's product. a) Using graphs explain how the industry adiusts to a new long-run equilibriumm. b) What happens to price, quantity, firm profits and the number of firms during the adiustment process?
6. Suppose that the trucking market is a perfectly competitive industry in long run equi librium. Each of the identical trucking firms has the same (long run) cost function: TC = 2250 + 10q2, where q is the volume of sales by each establishment. Each of the identical firms therefore have the same marginal cost: MC = 20q (a) What is the average cost function for the identical trucking firms? (b) How much does each individual firm produce in the...
The loss of a perfectly competitive firm which shuts down in the short run: Multiple Choice O is equal to its total variable costs. O O ь is zero. гето. O is equal to its total fixed costs. cannot be determined. Refer to the diagrams, which show the demand and cost curves for a perfectly competitive firm producing output and the demand and supply curve for the industry in which it operates. Which of the following is correct? ATC AVC...
11. Kites are manufactured by identical firms in a perfectly competitive environment. Each firm’s long run average cost and marginal cost of production are given by: AC = Q + 100/Q and MC = 2Q where Q is the number of kites produced. a) In long run equilibrium, how many kites will each firm produce? (2 pts) b) What will the price of kites (P) be? (1 pt) c) Suppose the demand for kites is given by formula Q =...
Consider the following statements. I. In the long run, every firm in a perfectly competitive industry will make an economic profit of zero. II. In the short run, every firm in a perfectly competitive industry will make the same economic profit. III. In the long run, firms in perfectly competitive industries must be productively efficient. I and II are true; III is false. I and III are true; II is false. I and III are false; II is true. All...
Suppose that a particular firm is in a perfectly competitive constant-cost industry. When it is using the optimal amount of capital for the long-run, total cost is C(q)=1000+(q2/10), ATC(q)=(1000/q)+q/10, and marginal cost is MC(q)=2q/10. This implies that ATC=MC at a quantity of 100 and a per unit cost of $20. 1. At what quantity is average total cost minimized? 2. What is the long-run competitive equilibrium price? 3. If market demand is QD=12,000-200P and short-run market supply is QS=300P, what...
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
