Abstract

We investigate investor behavior in a counterfactual scenario where shareholders are subject to a carbon tax, and we compare the structure and performance of the carbon-adjusted portfolio to those of the mean-variance portfolio. Results suggest that applying such a tax does not lead to significant changes in portfolio structure. The impact on performance becomes relatively noticeable only if the tax is particularly stringent. Therefore, implementing a carbon tax could be justified, as it may support decarbonization, at least partially, without significantly affecting investors’ economic outcomes.

碳调整投资组合选择：反事实分析

我们调查了在股东需缴纳碳税的反事实情景下的投资者行为，并比较了碳调整投资组合与均值方差投资组合的结构和表现。结果表明，征收碳税不会导致投资组合结构发生重大变化。只有当征税特别严格时，对业绩的影响才会相对明显。因此，实施碳税是合理的，因为它可以支持去碳化，至少是部分支持，而不会对投资者的经济结果产生重大影响。

期刊介绍： Many economists today are concerned by the proliferation of journals and the concomitant labyrinth of research to be conquered in order to reach the specific information they require. To combat this tendency, Economics Letters has been conceived and designed outside the realm of the traditional economics journal. As a Letters Journal, it consists of concise communications (letters) that provide a means of rapid and efficient dissemination of new results, models and methods in all fields of economic research.
