# Significance Of Relative Percentage Changes, The Size And Sign Of The Coefficient Of: Cross Elasticity Of Demand

➡️ Cross elasticity of demand measures the responsiveness of the quantity demanded of one good to a change in the price of another good.
➡️ A positive cross elasticity of demand indicates that an increase in the price of one good leads to an increase in the demand for the other good.
➡️ A negative cross elasticity of demand indicates that an increase in the price of one good leads to a decrease in the demand for the other good.
➡️ The size of the coefficient of cross elasticity of demand indicates the magnitude of the change in demand for one good in response to a change in the price of the other good.
➡️ The sign of the coefficient of cross elasticity of demand indicates the direction of the change in demand for one good in response to a change in the price of the other good.

### What is the significance of relative percentage changes in cross elasticity of demand?

Relative percentage changes in cross elasticity of demand indicate the responsiveness of the demand for one good to changes in the price of another good. It helps in understanding the degree of substitution between two goods and their impact on each other's demand.

### How does the size of the coefficient of cross elasticity of demand affect the market?

The size of the coefficient of cross elasticity of demand determines the degree of substitution between two goods. If the coefficient is high, it indicates that the goods are close substitutes, and a change in the price of one good will have a significant impact on the demand for the other good. This can lead to a shift in the market equilibrium.

### What is the significance of the sign of the coefficient of cross elasticity of demand?

The sign of the coefficient of cross elasticity of demand indicates the direction of the relationship between the two goods. If the coefficient is positive, it indicates that the goods are substitutes, and an increase in the price of one good will lead to an increase in the demand for the other good. If the coefficient is negative, it indicates that the goods are complements, and an increase in the price of one good will lead to a decrease in the demand for the other good.
