Document Summary
And shutting down production shutdown point is when you are outputting the least amount. At the price and quantity at which avc is a minimum. In perfect competition, market demand is downward sloping and demand faced by the individual firm is perfectly elastic. Price taker produces tiny proportion of the total output of a particular good on buyers are well informed about the prices of other firms. Profit maximizing output is when mc intersects with mr (like eq) When atc is below the mr curve there is economic profit, when atc is above mr. To construct the short run supply curve, we sum the quantities supplied by all the firms at each price. Firm in a competitive market are incurring an economic loss. Some firms exit, supply decreases, and the price rises until in the long run all firms are making normal profit. Market output decreases and the output of each remaining firm increases room for many firms in market.
