In the debate about food waste, pricing mechanisms used in marketing are criticized to trigger consumers to over-purchase and consequently waste food. Despite the ambiguity of the scientific results on the matter, the criticism persists, prompting many retailers to abolish 'buy one get one free' price promotions. However, evidence whether this initiative is justified are lacking. In this paper we aim to empirically explore the relation between retail price promotions and household level food waste. We collected actual food waste data, gathered discount shopping behaviour data through shopping receipts, as well as attitudinal data through a questionnaire from a sample of 118 households in Denmark. Our results provide evidence to counter the criticism and show that households with the largest actual proportion of food bought on discount waste less food, as well as those who are environmentally conscious, whereas larger households and those who lack skills in food practices waste more food.
在关于食物浪费的争论中，营销中使用的定价机制受到批评，因为这些机制会促使消费者过度购买，从而导致食物浪费。尽管关于这个问题的科学结果存在不确定性，但批评仍然存在，促使许多零售商取消了“买一送一”的价格促销活动。然而，缺乏这一举措是否合理的证据。在本文中，我们旨在通过实证研究来探讨零售价格促销与家庭层面食物浪费之间的关系。我们收集了实际的食物浪费数据，通过购物收据收集了折扣购物行为数据，以及通过丹麦的 118 户家庭的问卷调查收集了态度数据。我们的研究结果提供了反驳批评的证据，表明那些大量购买折扣食品的家庭、那些有环保意识的家庭以及那些有食品实践技能的家庭浪费的食物较少，而那些家庭规模较大、缺乏食品实践技能的家庭浪费的食物较多。
