important conditions for price discrimination to take place:
- A seller must possess monopoly power if it is to practice price
discrimination. If the monopoly power is absent, a seller is not
able to charge some customers a higher price than the others. In
the case of perfectly competitive markets, price discrimination is
ruled out because uniform price must prevail in the market in which
homogenous product is sold and producers have no control over the
market price.
- The concept of price discrimination can be successfully pursued
when it is possible to divide the monopoly market into separate
submarkets (by branding it may be possible).
- Price discrimination is possible only when the elasticity of
demand is different in different markets. When demand is inelastic,
a monopolist will fix a higher price in the market and lower prices
in the case when demand is elastic. However, price discrimination
is ruled out in case the elasticity of demand is the same across
different markets.
- Price discrimination is possible when a unit of the commodity
cannot be transferred from a cheaper market to an expensive one and
when price elasticity of demand is different in different
markets.
