Across-Design Uncertainty in Short Pricing Panels: Inference and Identification

本文指出,短观测定价面板中因价格变动稀少而产生的稀疏性,导致标准统计方法遗漏了由特定价格历史引发的跨设计误差。研究通过模拟发现,这种跨设计变异构成了估计误差的主要来源,致使常规置信区间显著低估不确定性。首先,跨设计误差随总价格变动量的增加而可预测地降低;其次,仅增加具有相同价格走势的区域数据无法解决问题,唯有结合独立价格轨迹的单元数据才能提升精度;第三,对独立定价单元应用简单的方差分量调整即可恢复准确的统计覆盖度。研究利用真实商店扫描数据验证了这些发现,表明产品和定价区域表现出的独立价格变动数量远少于其原始计数所示。最终结论指出,被动定价数据的可靠推断需要真正的独立变异,这可通过受控的区域价格测试实现。
