If there is no change in demand for good X with the change in the price of good X, then the price elasticity of demand for good X is:- |
Perfectly elastic Perfectly inelastic Unitary elastic Greater than 1 |
Perfectly inelastic |

Perfectly inelastic demand i.e. ed = 0. The following picture is a graphical representation of a perfectly inelastic demand curve:
