Elasticity refers to the responsiveness of a variable to a change in another variable. In economics, it is often used to measure the responsiveness of the quantity demanded or supplied to a change in price, income, or other factors that affect demand or supply.

There are several types of elasticity in economics, including price elasticity of demand, price elasticity of supply, income elasticity of demand, and cross-price elasticity of demand.

Price elasticity of demand measures the responsiveness of the quantity demanded to a change in price. It is calculated as the percentage change in quantity demanded divided by the percentage change in price.

Price elasticity of supply measures the responsiveness of the quantity supplied to a change in price. It is calculated as the percentage change in quantity supplied divided by the percentage change in price.

Income elasticity of demand measures the responsiveness of the quantity demanded to a change in income. It is calculated as the percentage change in quantity demanded divided by the percentage change in income.

Cross-price elasticity of demand measures the responsiveness of the quantity demanded of one good to a change in the price of another good. It is calculated as the percentage change in quantity demanded of one good divided by the percentage change in the price of another good.

Understanding elasticity is important for businesses and policymakers to make decisions about pricing, production, and taxation. With this knowledge, they can anticipate how consumers and producers will respond to changes in market conditions and make informed decisions about how to react.
