To shed light on individuals’ willingness to pay for “green” goods (i.e., goods that are supposed to have lower adverse environmental impacts either in production or in use), we study data from the introduction by Patagonia, Inc., of organic cotton sportswear in the mid-1990s. Patagonia, a maker of high-end outdoor wear, substituted organic cotton for conventionally grown cotton in all of its sportswear (i.e., casual clothing for travel and leisure) in 1996. We find that customers were willing to pay significant premiums for organic cotton garments although the organic cotton provided no demonstrable private incremental benefits to the customer.
