Tests of Weak Separability in Disaggregated Meat Products
利用扫描数据和Rotterdam模型对21种细分肉类产品进行弱可分性参数检验，发现消费者既不在同一肉类的不同部位或品质间选择，也不在不同肉类的相似品质间选择，所有产品分组均拒绝弱可分性假设。
Abstract Parametric tests of weak separability are conducted among twenty‐one disaggregate meat products, using scanner data and the absolute price version of the Rotterdam model. The tests indicate that consumers neither select among various cuts or qualities of a particular meat type nor select among meat types of like quality. Four partitions of the meat products are examined; in each case, the hypothesis of weak separability is rejected.
