Research of second degree price discrimination based on linear stochastic demand

摘要

Aiming at the ubiquitous uncertain demand, this article expands on the existing second degree price discrimination pricing tactic, and studies two problems under linear stochastic demand — the best demand interval and fixed discount rate. It is shown that the proportion of consumer surplus for the limit is 0.5. Furthermore, this article discusses the existence of optimal fixed discount rate and further compares the two price discrimination on the influence for profit.
