Testing for Consistent Aggregation
设计了可操作的实证程序，用于检验或设定供给（需求）价格加总器，并基于微观行为提供了加总的构建规则。实证检验发现美国农业部最常报告的加总价格缺乏支持，进而开发了与供给加总一致的新小麦价格指数。
Abstract This paper designs workable empirical procedures for testing or imposing supply (demand)‐price aggregators. Only single‐equation methods are considered to shift the focus from any particular optimizing paradigm toward the necessities for correctly tabulating firm‐level supplies (demands) and aggregate supply (demand). Both macro‐and micro‐level tests for consistent aggregation are developed. And constructive rules for aggregation based upon empirically observed micro behavior are provided in tabular form. Empirical tests reveal no support for the aggregate price most commonly reported by USDA. The constructive rules are then used to develop a new wheat‐price index consistent with supply aggregation.
