Efficient capacity pricing of the internet services

The paper examines the possibilities to improve efficiency in Internet pricing by introducing pre-purchase contract. One can regard pre-purchase market as a device for providing guaranteed services and as an alternative to smart market that can implement expected capacity pricing in an efficient manner. We find that the pre-purchase market tends to discriminate against the consumers who are less certain about their demands. We provide a condition under which the discriminatory effect is overwhelmed by the market force, which discourages the consumers with lower value by high premium. We also suggest a solution to the discriminatory effect.
