Goal-oriented preferences for green bonds: A model of sustainable investment strategies
Addressing climate change requires a transition to low-carbon, climate-resilient investments, with green bonds gaining traction among institutional investors focused on sustainability objectives. This study models their decision-making by integrating green investment targets into utility functions, combining a constant relative risk aversion (CRRA) component with a goal-oriented utility modification. Employing a Lagrangian approach, we derive the optimal terminal wealth and portfolio composition, including green bond allocation. Contrary to common intuition, more ambitious green investment targets do not always yield greater green bond allocations. The outcome significantly hinges on investors’ risk aversion. This intricate interaction between risk aversion and goal-oriented utility reveals the complexity of green investment decisions.
期刊介绍:
Economic Modelling fills a major gap in the economics literature, providing a single source of both theoretical and applied papers on economic modelling. The journal prime objective is to provide an international review of the state-of-the-art in economic modelling. Economic Modelling publishes the complete versions of many large-scale models of industrially advanced economies which have been developed for policy analysis. Examples are the Bank of England Model and the US Federal Reserve Board Model which had hitherto been unpublished. As individual models are revised and updated, the journal publishes subsequent papers dealing with these revisions, so keeping its readers as up to date as possible.
