中文摘要
我们利用来自近40个国家400多名专家的调查证据，研究碳价格建议的差异及其决定因素。我们量化了分歧程度，并揭示大多数专家能够在短期和中期全球碳价格水平以及大多数国家的单边碳价格水平上达成一致。大多数建议并未表现出单边碳价格低于全球碳价格的“搭便车”模式。此外，边境碳调节机制促进了更高的单边价格建议。我们展示了建议如何随其他调查回答以及国家和专家特征而变化。（JEL H43, Q54, Q58）
Abstract
We study the variation of carbon price recommendations and their determinants using survey evidence from more than 400 experts across almost 40 countries. We quantify the extent of disagreement and reveal that a majority of experts can agree on short- and medium-term global carbon price levels, and on unilateral carbon price levels in most countries. The majority of recommendations do not exhibit a “ free riding” pattern of lower unilateral than global carbon prices. Furthermore, border carbon adjustment facilitates higher unilateral price recommendations. We show how recommendations vary with additional survey responses, and with country and expert characteristics. (JEL H43, Q54, Q58)
