Title: An Analysis of Serial Allocation Rule in Group Buying
Abstract
When a seller offers quantity discount, buyers can aggregate their purchasing quantity to obtain lower prices. A cost allocation rule determines how much each buyer would pay for the amount they purchased. Various cost allocation rules have been used in practice. Different allocation rules
may have different influence on the buyers' behavior (i.e., their purchasing quantities). In this paper, we study the serial allocation rule and analyze the equilibrium purchasing quantity under this rule.
