Profits are zero, so the firm has no incentive to enter or exit We can use this model to analyze a change in demand both in the short and in the long run. The industry price is determined by the interaction of Supply and Demand, leading to a price of Pe. The individual firm will maximise output where MR = MC at QIn the long run firms will make normal profits. The SR equilibrium occurs at the intersection of the short run supply curve and D1 at pointbelow Perfect Competition: Evaluation { InsightsAllocative e ciency Perfect competition leads to the \optimal allocation of resources, achieved through P = MC (or MB = MC) in the long-run equilibriumLow prices for consumers Consumers bene t from low prices, due to the absence of abnormal pro ts, which would have led to a higher price A typical firm under perfect competition faces a horizontal demand curve. Suppose demand rises from D0 to D1, as shown below. The short-run equilibrium condition is given by p = MC = MR = AR. Total Revenue (TR) = pq, therefore Average Revenue (AR) = TR/q = pq/q = p Diagram for perfect competition. Suppose demand rises from D0 to D1, as shown below. Firms can enter or exit from the industry Hence, a competitive industry is in long run equilibrium if: Each firm has no incentive to change its method of production or the amount of output. In the short run, no new • define the conditions for perfect competition explain the conditions for profit maximisation derive the short-run supply curve of the individual firm explain long Perfect Competition: Evaluation { InsightsAllocative e ciency Perfect competition leads to the \optimal allocation of resources, achieved through P = MC (or MB = MC) in A typical firm under perfect competition faces a horizontal demand curve. So that at the given price, p, the firm can sell whatever amount it wishes to sell. We can use this model to analyze a change in demand both in the short and in the long run. The short-run The long-run equilibrium of the industry is illustrated in Figure(A) where the long-run price OP is determined by the intersection of the demand curve D and the supply curve Long-Run Industry Equilibrium Conditions: All factors of production are variable. What happens if supernormal profits are made? In the short run, no new firms can enter. So that at the given price, p, the firm can sell whatever amount it wishes to sell.
