Green premiums or economic pitfalls? Unraveling the profitability puzzle of credence attributes in agricultural supply chains
研究了有机等信用属性农产品如何影响供应链各环节的盈利，发现溢价主要让零售商受益，农民并未显著增收，无法改善价值分配失衡。
In recent decades, the promotion of agricultural products with Credence Attributes (CAs) like organic or environmentally friendly produce has aimed to increase value for farmers, since consumers are willing to pay a premium for such attributes. However, the hierarchical power structures in agricultural supply chains often prevent these premiums from significantly enhancing the profitability of all chain participants, particularly farmers. This paper delves into the impacts of CA production on the profitability of different supply chain members. Our analysis highlights that the financial outcomes for supply chain members are strongly influenced by the interplay between the demand for CA and non-CA products and their production costs. Notably, the study reveals that increased CA prices in the market do not uniformly translate into increased profitability across the supply chain, and particularly do not necessarily benefit the farmers. Rather, CA production and its price premiums continue to disproportionately benefit the retailer rather than the farmers, and thus fail to alleviate the imbalance in value distribution along the supply chain. • Higher premiums do not necessarily translate to increased earnings for farmers. • CA premiums primarily enhance retailer profitability rather than benefiting farmers. • The impact of CA production depends on the effectiveness of the production process.
