英文文献摘要：
A censored Almost Ideal Demand System (AIDS) and a Quadratic Almost Ideal Demand System (QUAIDS) were estimated in modeling non-alcoholic beverages. Five estimation techniques were used, including the conventional Iterated Seemingly Unrelated Regression (ITSUR), two-stage methods such as the Heien and Wessells (1990) and the Shonkwiler and Yen (1999) approaches, the generalized maximum entropy method and the Amemiya-Tobin framework of Dong, Gould and Kaiser (2004). Our results based on various specifications and estimation techniques are quantitatively similar and indicate that price elasticity estimates have a greater variability in more highly censored non-alcoholic beverage items such as tea, coffee and bottled water as opposed to less censored non-alcoholic beverage items such as carbonated softdrinks, milk and fruit juices.
在非酒精饮料建模中，估计了一个删尾的近似理想需求系统(AIDS)和一个二次近似理想需求系统(QUAIDS)。使用了五种估计技术，包括传统的迭代似不相关回归(ITSUR)，两阶段方法，如Heien和Wessells(1990)和Shonkwiler和Yen(1999)方法，广义最大熵方法和Dong、Gould和Kaiser(2004)的Amemiya-Tobin框架。我们的结果基于各种规格和评估技术定量相似,表明价格弹性估计有一个更大的可变性更高度审查不含酒精的饮料,比如茶、咖啡和瓶装水,而不是更少的审查不含酒精的饮料项目,如碳酸软饮料、牛奶和果汁。
