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.
Price elasticity of demand, also called the elasticity of demand, refers to the degree of responsiveness in demand quantity with respect to price. Consider a case in the figure below where demand is very elastic, that is, when the curve is almost flat.f demand is very inelastic, then large changes in price won't do very much to the quantity demanded. For instance, whereas a change of 25 cents reduced quantity by 6 units in the elastic curve in the figure above, in the inelastic curve below, a price jump of a full dollar reduces the demand by just 2 units.
