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.
If the purchase can be delayed, the demand for the product tends to be elastic. If it cannot be delayed it tends to be inelastic. For example, since I can wait to buy a new stereo until the price drops demand will vary greatly in accordance with price. This product thus would tend to be elastic. Gasoline, on the other hand, I cannot wait for. Thus demand does not vary greatly with price and the product tends to be inelastic.
