内容提要:
Despite the theoretical benefits of carbon pricing in combating climate change, many countries seem reluctant to adopt such policies. To address these concerns, we utilize the staggered enactment of carbon pricing initiatives across jurisdictions to evaluate their impacts on publicly listed firms worldwide. We observe triadic effects. First, carbon pricing initiatives impose a financial redistribution effect on firms, reducing the profitability of high-emission firms. Second, high-emission firms receive a lower market valuation, which is driven mostly by the cash flow channel as opposed to the discount rate channel. Lastly, high-emission firms also reduce investments. Importantly, carbon pricing initiatives do not reduce aggregate profitability, firm value, or investments in the policy-initiating country. Rather, they shift profits and investments from high- to low-emission firms, implying a net gain in carbon efficiency. Our results have significant normative implications.
尽管碳定价在应对气候变化方面具有理论上的好处,但许多国家似乎不愿采取这样的政策。为了解决这些问题,我们利用跨司法管辖区错开实施碳定价举措来评估其对全球上市公司的影响。我们观察到三重效应。首先,碳定价举措对企业产生了财务再分配效应,降低了高排放企业的盈利能力。其次,高排放公司获得的市场估值较低,这主要是由现金流渠道而不是贴现率渠道驱动的。最后,高排放企业也会减少投资。重要的是,碳定价举措不会降低政策发起国的总体盈利能力、公司价值或投资。相反,它们将利润和投资从高排放企业转移到低排放企业,这意味着碳效率的净收益。我们的研究结果具有重大的规范意义。
