Effects of health information on household demand for nutrients
研究健康饮食信息传播对家庭营养素消费的影响，发现信息几乎不改变营养素消费结构，有限效果被价格、收入和家庭构成变化抵消。
In an analysis of the effectiveness of the dissemination of information on healthy dietary intake, a consumer demand model for food nutrients is formulated. The model is constructed on the assumption that households maximise utility of non-marketed goods using market goods. In terms of food consumption, households are presumed to be subjected to both positive and negative information on dietary intake. Acting on this information, households may reallocate budgetary resources and therefore alter the bundle of goods consumed. This paper shows that information on healthy dietary intake has almost no effect on the bundle of nutrients consumed and what limited effects we observed are more that cancelled out by changes in nutrients' implicit prices, income and household composition.
