Price Discrimination

Where a monopoly exists, the price of a product is likely to be higher than in a competitive market and the quantity sold less, generating monopoly profits for the seller. These profits can be increased further if the market can be segmented with different prices charged to different segments (referred to as price discrimination), charging higher prices to those segments willing and able to pay more and charging less to those whose demand is price elastic. The price discriminator might need to create rate fences that will prevent members of a higher price segment from purchasing at the prices available to members of a lower price segment. This behaviour is rational on the part of the monopolist, but is often seen by competition authorities as an abuse of a monopoly position, whether or not the monopoly itself is sanctioned. Examples of this exist in the transport industry (a plane or train journey to a particular destination at a particular time is a practical monopoly) where Business Class customers who can afford to pay may be charged prices many times higher than Economy Class customers for essentially the same service. Microsoft and the Video industry generally also price very similar products at widely varying prices depending on the market they are selling to.
