An experimental approach to valuing information
提出一种直接测量标签信息价值的方法，通过德州两家杂货店的实地实验发现，新方法测得的原产地标签信息价值比传统方法低36%，且受民族中心主义和肉类消费频率影响。
This article proposes a method to directly measure the value of information (VOI) conveyed in a label. Using data collected from a field experiment conducted in two grocery stores in Texas, we find the VOI contained in U.S. federally mandated country of origin labels for beef and pork is 36% lower using the new direct elicitation compared to the conventional approach. The mean value-of-origin information, in the context of our experiment, ranges from $0.016 to $1.08 per pound of steak/chop purchased, depending on the valuation method used and assumptions about labeling knowledge and average volume purchased per choice. The VOI is substantively influenced by ethnocentrism and meat consumption frequency.
