Technical Note—A Monge Sequence-Based Approach to Characterize the Competitive Newsvendor Problem
研究了多个报童在需求不确定且未满足需求会溢出到其他报童时的竞争博弈，通过将溢出行为转化为运输问题中的虚拟成本来复制各报童的现金流，从而分析问题结构并确定均衡。
Replicating cash flows of multiple agents in game-theoretic settings tends to be a challenging task. In this paper, we consider the competitive newsvendor game where multiple newsvendors choose inventory levels before demand arrival and the unmet demand of each newsvendor spills over to multiple other newsvendors. We show that this spillover behavior and the resulting cash flows of each newsvendor can be replicated within a transportation problem after assigning artificial costs on spillover behavior. This replication provides an opportunity to study structural properties of the problem, as well as determine the equilibrium of the game. This paradigm of using artificial costs within an optimization framework to replicate agents’ cash flows can be used in many other games as well.
