At Q2, (P, AR is greater than ATC) and therefore the firm now makes supernormal profit.

A firms marginal cost (MC) curve is effectively its supply curve.

Due to the rise in price to P2, profits are now maximised at Q2.

Market demand rises from D1 to D2 causing the price to rise from P1 to P2.At this price firms make normal profits – because average revenue (AR) = average cost (AC)Ĭhanges in Perfect Competition equilibrium.A firm maximises profit at Q1 where MC = MR.Individual firms (on the left) are price takers.This sets the market equilibrium price of P1.The market price is set by the supply and demand of the industry (diagram on right).In the long-run firms in perfect competition will make normal profits.Therefore firms have an elastic demand curve.
