The price elasticity of demand is the percentage change in the quantity demanded of a good or service divided by the percentage change in the price. The price elasticity of supply is the percentage change in quantity supplied divided by the percentage change in price.
Price elasticity of demand refers to how changes to price affect the quantity demanded of a good. Conversely, price elasticity of supply refers to how changes in price affect the quantity supplied of a good. Price Elasticity of Demand. There are three main types of price elasticity of demand: elastic, unit elastic, and inelastic.
The price elasticity of demand is the percentage change in the quantity demanded of a good or service divided by the percentage change in the price. The price elasticity of supply is the percentage change in quantity supplied divided by the percentage change in price.
Learn about the price elasticity of demand, a concept measuring how sensitive quantity is to price changes. Elasticity is calculated as percent change in quantity divided by percent change in price. Elastic situations have elasticity greater than 1, while inelastic situations have elasticity less than 1.

- No, you cannot use slope to represent elasticity. Elasticity is not comparing the nominal change in quantity to the nominal change in price. Rather...
- The midpoint formula can be used in any case for price elasticity cases. However, as mentioned in the video, it is outside the current course. It i...
- It does. This can be done by doing unit analysis. The unit of the change in percentage of quantity demanded is the amount of that product (kg, cars...
- In future videos it is likely that more "points" are being used. If it is just one quantity, then we would put the original quantity in the numerat...
- Hey Seb! If elasticity were to be negative, that would mean people would buy more of the good when the price was hiked. If that sounds wrong, that'...
The key difference is that the price elasticity of supply is focused on the supply side instead of the demand side. The price elasticity of supply formula is essentially the same as the PED formula, but the numerator is the percentage change in quantity supplied instead of demanded.
Demand is price inelastic if the absolute value of the price elasticity of demand is less than 1; it is unit price elastic if the absolute value is equal to 1; and it is price elastic if the absolute value is greater than 1.

Supply is price elastic if the price elasticity of supply is greater than 1, unit price elastic if it is equal to 1, and price inelastic if it is less than 1. A vertical supply curve, as shown in Panel (a) of Figure 5.11 “Supply Curves and Their Price Elasticities”, is perfectly inelastic; its price elasticity of supply is zero.
