Carbon Risk Premium and Worries about Climate Change [Link]
Abstract. This paper sheds light on the impact of investor worries about climate change on the pricing of emission (carbon-intensive) and clean (low-emission) stocks. We estimate the carbon risk premium in a cross-section of over 4,800 firms in 21 countries. We do not find evidence of a carbon risk premium when investor worries about climate change are low. Moreover, the carbon premium is significant for medium-high quantiles of the return distribution when investors’ worries are high. Overall, our results are consistent with an interpretation that non-worried investors are not demanding compensation for their exposure to carbon emission risk.
Global Risk and Ambiguity in the determination of CDS Spreads
with Amirhossein Sadoghi.
Abstract. We construct a daily time series of several types of global risks and related ambiguity using news about risk published by major international newspapers. We propose a novel approach to measure ambiguity. First, we perform topic modelling on risk-related news. Then, we compute the ambiguity of a given topic as the expected volatility of probabilities based on the latent Dirichlet allocation (LDA) algorithm. Next, we empirically test the prediction that global risks and related ambiguity have explanatory power of credit default swap (CDSs) spreads. We find that an increase in ambiguity leads to a decrease in CDS spreads of up to 10 bps. Conversely, an increase in risk is associated with an increase in CDS spreads.
