Sustainable portfolio optimization and sustainable taxation
We consider the optimal investment problem under sustainability requirements stated in [7], but solve it explicitly for the wider class of power utility functions. Further, we introduce a type of equilibrium framework that consists of modifications of the market coefficients such that the unconstrained optimal portfolio process will already satisfy the sustainability constraint. We call this modification sustainable taxation as it indicates possible taxation activities by the state to steer investors towards sustainable assets.
