Experiments on Green Goods

绿色产品是具有环保效益的日常产品。例如，碳中性的航空公司航班就是一种绿色产品。也许，绿色商品的存在会带来更大的环境保护。但通常情况下，只有一小部分的价格被用于环境保护，这是一种被称为“绿色洗礼”的特征。利用经济学实验，我们发现，为受试者提供购买绿色商品的机会可能会导致对环境事业的总贡献下降。因为他们购买绿色商品，受试者不再为环境事业单独捐款。与此同时，一些受试者愿意付钱来避免道德困境，因为他们被要求为环境公益事业做出贡献。总体而言，似乎绿色商品可以导致用于环境事业的资金减少。

Green goods are everyday products with an environmental benefit attached. For instance, a carbon-neutral airline flight is a green good. Possibly, the existence of green goods leads to greater environmental protection. But often, only a small fraction of the price goes towards environmental protection, a feature labelled' greenwash'.Using economics experiments we find that offering subjects the chance to buy a green good can lead to a drop in total contributions to the environmental cause. Because they buy the green good, subjects stop making separate donations to the environmental cause. Meanwhile, some subjects are willing to pay money to avoid a moral dilemma where they are asked to contribute to the environmental good cause.Overall it seems green goods can lead to less money going to environmental causes.
