Experiments on Green Goods

绿色商品是具有环境效益的日常产品。例如，碳中和的航空公司航班是一种绿色商品。可能，绿色商品的存在导致更大的环境保护。但通常情况下，只有一小部分的价格用于环保，这是一个被称为“漂绿”的特征。通过经济学实验，我们发现，让受试者有机会购买绿色商品，可能会导致对环保事业的总贡献下降。因为他们购买了绿色商品，受试者不再单独为环保事业捐款。与此同时，一些受试者愿意付钱以避免道德困境，他们被要求为环境公益事业做出贡献。总的来说，绿色商品似乎会导致用于环境公益事业的资金减少。

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.
