标题： The Green Premium Puzzle: Empirical Evidence from Climate-Friendly Food Products

摘要： 本文研究了环保食品产品在消费者市场中是否具有价格溢价。 使用瑞典一家超市的产品层面数据，我们考察了包装正面的气候影响评分与零售价格之间的关系，同时控制产品尺寸、营养成分和固定效应。 与预期的积极绿色溢价相反，我们没有发现环保产品定价更高的证据。 在某些产品类别中，气候评分更好的产品实际上与较低的价格相关，这表明存在负溢价，这一结果引发了我们所谓的绿色溢价谜题。 我们认为，市场摩擦因素如竞争性的消费者优先事项、对气候问题的心理距离以及对环境标签的怀疑可能抑制了旨在奖励可持续消费的价格信号。 这些发现为寻求在向更可持续社会过渡过程中将气候目标与有效的市场激励措施相结合的生产商、零售商和政策制定者提供了重要的见解。 显示英文摘要

摘要： This paper investigates whether climate-friendly food products command a price premium in consumer markets. Using product-level data from a supermarket in Sweden, we examine the relationship between front-of-package climate impact scores and retail prices, controlling for product size, nutritional content, and fixed effects. Contrary to the intuitive expectation of a positive green premium, we find no evidence that climate-friendly products are priced higher. In some product categories, products with better climate scores are in fact associated with lower prices, suggesting a negative premium, an outcome that gives rise to what we refer to as the green premium puzzle. We argue that market frictions such as competing consumer priorities, psychological distance from climate issues, and skepticism toward environmental labeling may suppress the price signals intended to reward sustainable consumption. These findings offer important insights for producers, retailers, and policymakers seeking to align climate goals with effective market incentives in the transition toward a more sustainable society.
