Economic Analysis of Food Values: An International Comparison Study

人们的食物选择可以用他们对更抽象的食物质量属性或所谓的“食物价值”的偏好来解释。本研究建议使用陈述偏好法（即，最佳-最差缩放（BWS）方法）。我们对日本进行了在线BWS选择实验，并比较了美国和欧洲的结果（Bazzani et al.，2018年）。食物价值信息以及人口统计数据是从日本所有地区和所有年龄组的3，000人中收集的，考虑到地理和世代代表性。这是为了比较世界不同地区不同经济发展阶段的经济体的粮食价值。

People’s food choices can be explained by their preferences for more abstract food quality attributes or so called “food values”. This study proposes to examine food values using a stated preference method (i.e., best-worst scaling (BWS) approach) in Asia, the United States (US) and Europe.We conducted online BWS choice experiments for Japan and compared the results from the United States and Europe (Bazzani et al., 2018). The food value information as well as demographical data were collected from a sample of 3,000 persons from all the regions and all the age groups considering geographical and generational representations in Japan. This was to compare the food values for the economies with different stages of economic development in different regions of the world.
