| 单词 | point elasticity |
| 释义 | point elasticity The ratio of a proportional change in one variable to that of another, measured at a point. For example, if p is price and q is quantity, the elasticity of demand is defined as -(p/q) (dq/dp). This is the limit of -(Δq/q)/(Δp/p) as Δp and Δq tend to zero. In contrast to arc elasticity, which is defined for finite changes in p and q and can thus be based on direct measurement, point elasticity can only be found by statistical inference, fitting a continuous function q = f (p) to the actual observations, and calculating the elasticity by differentiating this function. |
