我们调查了消费者对受益虫保护和受农药保护的食用和非食用植物的支付意愿,以及信息框架对支付意愿的影响。我们在德国以罗勒、石楠和兰花为实验对象,进行了两个国家选择实验(一个实验室在田间实验和一个在线实验)。在这两个实验中,我们都发现了强有力的证据,表明消费者更喜欢受益虫保护的植物。此外,我们发现,信息框架会影响消费者的支付意愿,其中获得框架产生更大的整体支付意愿。为了检查我们的结果的稳健性,我们实施了一些工具来减轻对社会期望和假设偏见的担忧,发现我们的结果在我们的关键发现方面是稳健的。这是第一个专门针对消费者对受益虫保护的植物的支付意愿的综合性实验研究。我们的研究结果对从业者很有价值,因为在温室生产中使用益虫已经相当普遍。根据我们的结果,这些信息可以成功地用于营销目的。
We investigate consumers’ willingness to pay for edible and non-edible plants protected by beneficial insects and those protected by pesticides, respectively, as well as the influence of message framing on willingness to pay. We use basil, heather, and orchids as experimental objects in two stated-choice experiments (one lab-in-the-field experiment and one online experiment) conducted in Germany. In both experiments, we find strong evidence that consumers prefer plants protected by beneficial insects. Moreover, we find that message framing affects consumers’ willingness to pay, where gain framing produces greater overall willingness to pay. To check for the robustness of our results, we implemented instruments to mitigate concerns for social desirability and hypothetical bias, finding that our results are robust in terms of our key findings. This is the first comprehensive experimental study specifically on consumer’s willingness to pay for plants protected by beneficial insects. Our findings are valuable for practitioners, as the use of beneficial insects in greenhouse production is already rather common. Following our results, this information could be successfully used for marketing purposes.
