Abstract: The widespread use of dynamic pricing strategy has trained customers to be more and more strategic,that is,when customers time their purchase,they not only consider whether the price offered is be-yond their reservation prices,but also consider the possibility of getting it when the price is marked down, therefore,they may delay their purchase.Aclass of multi-product new svendor problem with a budget constraint when considering strategic customer behavior is studied.The rational expectation equilibrium analysis is int roduced and the rational expectation equilibrium solution to the static game between the new svendor and the strategic customers is obtained.The impact of quantity commitment on the equilibrium quantity and equilibrium price is further analyzed.The properties of the optimal solutions are analyzed and asolution procedure is also presented.At last,numerical examples are given to illust rate the conclusions of the proposed model.

Key words: multi-product new svendor problem, strategic customer behavior, rational expectation equilibrium, budget constraint, pricing
