Flexible Demand Systems with Serially Correlated Errors: Fat and Oil Consumption in the United States
使用Lewbel提出的灵活需求系统，估计1950-1986年美国脂肪和油脂需求，发现该模型优于Translog和AIDS模型，且修正序列相关很重要；价格、收入效应及公共健康关注是主要决定因素。
Abstract A flexible demand system proposed by Lewbel is used to estimate U.S. fat and oil demand from 1950 to 1986. Results suggest that the Lewbel model outperforms the Translog and AIDS and that correction for serial correlation is important. Findings also suggest that price and income effects, together with increasing public health concerns, primarily determine U.S. fat and oil demand.
