Estimating Interrelated Demands for Meats Using New Measures for Ground and Table Cut Beef
估计了两套肉类需求方程系统，分别使用传统和新的碎牛肉与切块牛肉度量，发现分解方式显著影响汉堡和切块牛肉的需求弹性，并通过多变量PE检验拒绝了非育肥牛肉模型，但未拒绝使用新度量的碎牛肉模型。
Abstract Two systems of demand equations for meats ate estimated using traditional and new measures of ground and table cut beef. The choice of disaggregation has a significant impact on estimated demand elasticities for hamburger and table cuts. A multivariate version of the P E ‐test is used as a nonnested test of the alternative specifications. The P E ‐test is an appropriate nonnested specification test when the models in question have different (but related) dependent variables. The P E ‐test rejects the nonfed beef model specification but does not reject the ground beef model, which uses the new measures of ground and table cut beef.
