In general, the demand for a good is said to be inelastic (or relatively inelastic) when the PED is less than one (in absolute value): that is, changes in price have a relatively small effect on the quantity of the good demanded.
Examples of price inelastic demand. We say a good is price inelastic, when an increase in price causes a smaller % fall in demand, e.g. if price of petrol falls 30%, but demand for petrol only increases 10% the PED = â 0.33.
