碳税挤出低碳选择：来自消费者实验的证据
Carbon taxes crowd out low-carbon choices: Evidence from a consumer experiment
摘要
We examine the impact of a carbon tax on consumer choices via a large-scale online randomized controlled trial. Higher taxes generally reduce the demand for high-carbon goods. Compared to an import tax, a carbon tax reduces demand when the tax is zero (i.e., announced but not levied) but leads to relatively higher demand for high-carbon goods when a positive tax is introduced. This difference in demand responses, despite identical prices, is concentrated among climate-concerned consumers. Our findings suggest that carbon taxes can crowd out the effect of climate concerns on consumer choices, with important implications for policy.
中文摘要
我们通过一项大规模在线随机对照试验考察碳税对消费者选择的影响。一般而言，较高的税负会降低对高碳商品的需求。与进口税相比，碳税在税率零时（即已宣布但未征收）会降低需求，但在引入正税率时会导致对高碳商品相对更高的需求。尽管价格相同，这种需求反应的差异集中于关注气候的消费者。我们的发现表明，碳税可能挤出气候关注对消费者选择的影响，这对政策具有重要启示。
