The demand for necessaries and comforts is less elastic than the demand for luxuries. A slight decrease in the prices of common table salt or matches, for example, would be unlikely to increase appreciably the demand for either of these commodities. Even a sharp decrease in price would cause few people to increase their consumption of either, simply because more salt in the food or more matches on the shelf are not desired. Bread also has an inelastic demand, but to a less extent than salt or matches. So also have the plainer kinds of food, the more common articles of wear, and all the other goods that enter into everyday consumption. In Fig. 1, curve II' represents an inelastic demand. It will be noticed that it is much more abrupt than the more gentle elastic curve EE'. At the price OP' (VW) we assume that the volume of demand is OV (P'W). As the price declines the increase in demand is slight. At the new price OF (VW) the demand is OV' (PW), which is slightly more (VV') than it was at the old price.
