When is Environmentalism Good for the Environment?
研究了环保主义供给如何影响企业定价和产品选择，进而影响全球污染水平。发现高环保主义供给可能因增强绿色企业市场势力而恶化环境，但可补充最低环境标准等传统政策。
Abstract We study how the supply of environmentalism, which is defined by psychic benefits (costs) associated with the purchase of high-environmental (low-environmental) qualities, affects the way firms choose their prices and products and the ensuing consequences for the global level of pollution. Contrary to general belief, a high supply of environmentalism does not necessarily give rise to a better environmental outcome because it endows the green firms with more market power which they use to charge higher prices. Nonetheless, environmentalism can be used to effectively complement more traditional policy instruments such as a minimum environmental standard.
