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.
There are two types of price elasticity: price elasticity of supply and price elasticity of demand. The price elasticity of supply measures the responsiveness to the supply of a good or service after a change in its market price. According to basic economic theory, the supply of a good increases when its price rises. Conversely, the supply of a good decreases when its price decreases. Price elasticity of supply measures the percentage change in supply divided by the percentage change in price.
