Newsvendor Demand Chasing Revisited
研究发现现有识别报童需求追逐行为的指标容易产生大量误报，提出用简单相关系数作为替代，帮助研究者更准确判断决策者是否真的在追逐需求。
Existing research on newsvendor behavior asserts that individuals engage in demand chasing—adjusting their order quantities towards prior demand. Several metrics have been used to identify this heuristic. By simulation, current metrics are shown to yield excessive false positives, indicating demand chasing when the true order generating process is independent of prior demand. A simple correlation measure does not suffer from this problem and is proposed here as an alternative to some of the more commonly used measures.
