Information, Health Risk Beliefs, and the Demand for Fats and Oils
在油脂需求系统中纳入胆固醇和饱和脂肪健康信息的均值和方差度量，基于贝叶斯健康风险信念模型和消费者意识调查计算这些指标，发现健康信息显著增加了玉米油、棉籽油和豆油的消费，减少了黄油和猪油的消费。
Mean and variance measures of health information about cholesterol and saturated fat are included in a demand system for fats and oils. A Bayesian model of health risk belief and consumer awareness surveys are the basis for computing these measures. The empirical demand model shows that health information has resulted in significant increases in consumption for corn, cottonseed, and soybean oils and decreased consumption for butter and lard. The predicted demand effects based on the Bayesian information model are more reasonable than predictions from using either a time trend or a simple cumulative cholesterol information index.
