Cryptocurrency, green and fossil fuel investments

Abstract

This paper investigates the time-varying spillovers among cryptocurrency, green and fossil fuel investments. Using a TVP-VAR network connectedness model, we find that the spillovers among cryptocurrency, green and fossil fuel assets vary over time and that they are more pronounced during crisis periods. Our results also reveal asymmetric spillovers among these assets, where negative return spillovers are larger than positive return spillovers. We conclude our paper by discussing the implications of our results for policymakers and investors.
