Supply Ep = Percentage change in quantity supplied / Percentage change in price Supply often becomes less elastic as quantity rises, due to capacity limits. Supply is elastic if quantity supplied responds substantially to changes in the price. In this case Supply Ep > 1 Supply is inelastic if quantity supplied responds only slightly to changes in the price. In this case Supply Ep < 1. Supply has unit elasticity if the quantity moves the same amount proportionately as the price. In this case Supply Ep = 1 A vertical supply curve is perfectly inelastic (Elasticity =0). A horizontal supply curve is perfectly elastic (Elasticity =Infinity). 6

The more easily sellers can change the quantity they produce, the greater the price elasticity of supply. For many goods, price elasticity of supply is greater in the long run than in the short run, because firms can build new factories, or new firms may be able to enter the market.
