Making or Buying Environmental Public Goods: Do Consumers Care?
通过722名受访者的陈述偏好调查，发现消费者更愿意为生产者自行减排（制造）而非购买碳抵消（购买）支付溢价，但控制本地外部性后，消费者对购买抵消也有显著支付意愿。
Firms may voluntarily abate pollution using one of two options: internalizing their own external effects and incurring abatement costs (“making”), or delegating environmental protection by purchasing offsets (“buying”). We aim to elicit consumers’ willingness to pay for producers’ use of the “making” option as compared to the “buying” option, controlling for spatial effects (joint local public goods), and level of greenhouse gas emissions. Using a stated-choice survey of 722 respondents, we find consumers are more willing to pay for a “making” policy. Consumers do significantly care for the producers’ use of offsets when the level of local externalities is controlled for. <i></i>
