Choosing pollution control instrument is an important environmental policy decision. Carbon taxes and subsidies for emissions reductions are two commonly used environmental policies. In practice, the government may be restricted to use only one policy instrument. In this paper, we compare the social welfare effect between policies of a carbon tax and a subsidy. We show that as the marginal environmental damage of the high carbon product increases, the control instrument should change from a subsidy policy to a carbon tax policy. It also turns out that Bertrand competition does not always incur a higher social welfare than Cournot competition when the government intervenes with a pollution control policy.
选择污染控制工具是一项重要的环境政策决策。碳税和减排补贴是两种常用的环境政策。在实践中，政府可能只能使用一种政策工具。本文比较了碳税和补贴政策的社会福利效应。结果表明，随着高碳产品的边际环境损害的增加，控制工具应从补贴政策转变为碳税政策。研究还表明，当政府采取污染控制政策进行干预时，伯特兰竞争并不总是比古诺竞争产生更高的社会福利。
