小规模农场的可持续性认证在发展中国家获得了相当大的势头。然而，关于认证计划对国内消费的食品和饮料的经济效益的证据很少。本文通过评估可持续发展标准对越南小规模特色绿色茶种植的销售价格、销售额、成本和净收入的影响来解决这一差距。我们分析了401个小型绿色茶农的原始调查数据，并采用倾向得分匹配来减轻自我选择偏差。我们的估计显示，认证的绿色茶生产商能够获得更高的平均销售价格和销售价值。此外，虽然认证导致雇用劳动力的成本大幅增加，但农场净收入仍有显著提高。
Sustainability certification for small-scale farms has gained considerable momentum in developing countries. However, evidence on the economic benefits of certification schemes in the context of domestically consumed foods and beverages is scarce. This paper addresses this gap by evaluating the impacts of sustainability standards on the selling prices, sales, costs and net income of small-scale specialty green tea farming in Vietnam. We analyze original survey data on 401 smallholder green tea farmers and employ propensity score matching to mitigate self-selection bias. Our estimates reveal that certified green tea producers are able to obtain a higher average selling price and sales value. In addition, although certification leads to a dramatic increase in the costs of hired labor, net farm income is still significantly improved.
