Suitable terminology for the inverse elasticity? In many microeconomic applications (e.g. monopoly price-setting) the inverse elasticity appears. Explaining such relations to laymen is often awkward because inverse proportionality is not as intuititve as direct proportionality. 

In physics, there are often separate terms for inverses of important concepts (e.g. electrical resistance and conductance are each other's inverse).

Question: is there a commonly used term for the inverse elasticity? If not, what would be a suitable term that is easily grasped by laymen?
Economists generally call it the "inverse elasticity". But note
$$\frac{1}{\eta}=\left(\frac{\partial Q}{\partial P}\frac{P}{Q}\right)^{-1}=\frac{1}{\left(\frac{\text{% change in quantity}}{\text{% change in price}}\right)}=\frac{\text{% change in price}}{\text{% change in quantity}}$$

Thus, whilst the price elasticity of demand can be interpreted as (roughly)


  The percentage change in quantity sold that would follow a one percentage point increase in the price.


the inverse elasticity (the "demand elasticity of price") could be explained as


  The percentage change in price necessary to achieve a one percentage point increase in quantity.
