INFJs tend to see helping others as their purpose in life, but while people with this personality type can be found engaging rescue efforts and doing charity work, their real passion is to get to the heart of the issue so that people need not be rescued at all.
Cross elasticity of demand Cross elasticity of demand (XED) is the responsiveness of demand for one product to a change in the price of another product. Many products are related, and XED indicates just how they are related.
The crossâprice elasticity of demand is the ratio of the percentage change in the quantity demanded of some good X to a percentage change in the price of some other good Y. The crossâprice elasticity of demand is given by the formula: If the percentage change in the quantity demanded of good X is greater than the percentage change in the price of good Y, the demand for good X is crossâprice elastic with respect to good Y, or very responsive to changes in the price of good Y.
