There are two types of price elasticity: price elasticity of supply and price elasticity of demand. The price elasticity of supply measures the responsiveness to the supply of a good or service after a change in its market price. According to basic economic theory, the supply of a good increases when its price rises. Conversely, the supply of a good decreases when its price decreases. Price elasticity of supply measures the percentage change in supply divided by the percentage change in price.
