Does Local Labeling Complement or Compete with Other Sustainable Labels? A Conjoint Analysis of Direct and Joint Values for Fresh Produce Claim
通过2008年美国调查的联合选择实验，分析了有机、公平贸易、碳足迹和本地生产等可持续标签的独立价值和交互效应，发现本地标签价值最高，且与公平贸易结合能增强价值，但碳密集型本地产品会受更大折扣。
As a way to explore the increasing use of sustainability labels in the marketplace, this study analyzes the differential values and interactive effects of sustainable production claims (organic, fair trade, and carbon footprint) and location claims through a conjoint choice experiment included in a 2008 U.S. survey. Locally grown is the highest valued claim, and its value is further enhanced with fair trade certification, but carbon‐intensive local products are discounted more severely than those sourced from other locations. Some negatively valued claims (imports and carbon footprint) can be mitigated by combining them with other claims (organic and fair trade).
