Carbon-adjusted portfolio selection: A counterfactual analysis
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.
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.
