point elasticity การใช้

• Like the point elasticity, the arc elasticity can vary in value depending on the starting point.
• If one point elasticity is used to model demand changes over a finite range of prices, elasticity is implicitly assumed constant with respect to price over the finite price range.
• This form of the equations shows that point elasticities assumed constant over a price range cannot determine what prices generate maximum values of \ ln ( Q ); similarly they cannot predict prices that generate maximum Q or maximum revenue.
• Constant elasticities can predict optimal pricing only by computing point elasticities at several points, to determine the price at which point elasticity equals-1 ( or, for multiple products, the set of prices at which the point elasticity matrix is the negative identity matrix ).
• Constant elasticities can predict optimal pricing only by computing point elasticities at several points, to determine the price at which point elasticity equals-1 ( or, for multiple products, the set of prices at which the point elasticity matrix is the negative identity matrix ).
• Constant elasticities can predict optimal pricing only by computing point elasticities at several points, to determine the price at which point elasticity equals-1 ( or, for multiple products, the set of prices at which the point elasticity matrix is the negative identity matrix ).
• The arc elasticity is used when there is not a general function for the relationship of two variables, but two points on the relationship are known . in contrast, calculation of the point elasticity requires detailed knowledge of the functional relationship and can be calculated wherever the function is defined.
