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.

An elastic demand or elastic supply is one in which the elasticity is greater than one, indicating a high responsiveness to changes in price. An inelastic demand or inelastic supply is one in …

The elasticity of supply or demand can vary based on the length of time you care about.

Elasticity of demand is not the slope of the curve. The percentage part of the equation is crucial. Use the formula Sal gives and test it by yourself. On a straight line, elasticity will be highest …

Now, it's important to note that the elasticity of demand, or actually supply, is not always constant for a given product. In fact, it can change at different price points.

The price elasticity of supply is a measure of how sensitive the quantity supplied of a good is to changes in price. It is calculated as the percentage change in quantity supplied divided by the …

In a previous lesson we learned about price elasticity of demand, but there are many other types of elasticity that measure how agents respond to variables other than the change in a good's …
