Gorman（1981）的恩格尔曲线“秩”的概念被扩展到任何需求系统。 排名有影响的规格，可分性，和聚合的需求。 一个简单的非参数检验秩恩格尔曲线数据的描述和应用到美国和英国。消费者调查数据。 该检验采用了一种新的一般方法来检验估计矩阵的秩。 结果用于评估代表性消费者模型的理论和经验聚集误差，并解释代表性消费者悖论。
Gorman's (1981) concept of Engel curve "rank" is extended to apply to any demand system. Rank is shown to have implications for specification, separability, and aggregation of demands. A simple nonparametric test of rank using Engel curve data is described and applied to U.S. and U.K. consumer survey data. The test employs a new general method for testing the rank of estimated matrices. The results are used to assess theoretical and empirical aggregation error in representative consumer models, and to explain a representative consumer paradox.
