Taste Changes in the Demand for Food by Demographic Groups in the United States: A Nonparametric Empirical Analysis
使用非参数技术分析美国不同收入、户主年龄和配偶教育水平的人口群体对19类主要食品的需求稳定性，发现群体间口味变化存在显著差异。
Abstract This study uses nonparametric techniques to analyze the stability of demand for nineteen major food categories among various demographic groups in the United States. Households are divided into population groups by income, the head's age, and the spouse's education level. The data used are from the 1980–90 “Diary” portion of the Bureau of Labor Statistics's annual Consumer Expenditure Survey. The programming model developed by Sakong and Hayes, with the modifications suggested by Chalfant and Zhang, is used to test for and measure taste changes. Substantial differences in preference trends between population groups are found for many of the food commodities.
