Recovering the Shadow Value of Nutrients
基于Gorman的效用理论模型，将食品单价与营养素的影子价值联系起来，利用最大熵原理估计28种营养素的影子价值，并分析结果。
This article investigates the shadow values of twenty‐eight different nutrients. It links the unit price of foods to the shadow values of nutrients by building on a utility theoretic model first proposed by Gorman. Maximum entropy principles are then used to reason consistently about the values of the parameters of interest. The resulting estimates are discussed and analyzed.
