The coefficient of price-elasticity of demand that is obtained at a point on the demand curve is called the point price- elasticity of demand and it is given by the formula 21 or 22.
Cross elasticity of demand XED is the responsiveness of demand for one product to a change in the price of another product. Percentage change in quantity demanded divided by the percentage change in price Since changes in price and quantity usually move in opposite directions usually we do not bother to put in the minus sign. Accordingly the demand of a good can be elastic.
This video shows how to find elasticity of demand and you have to determine where it elastic inelastic or unit elasticity. Many products are related and XED indicates just how they are related. Point-price elasticity of demand.
If demand is elastic revenue is gained by reducing price but if demand is inelastic revenue is gained by raising price. The more elastic a firm the more it can increase production when prices are rising and decrease its production when prices are falling. You should be careful in all circumstances to check which definition is being used.
