This paper studies the evolution of the greenium, i.e. a risk premium linked to firms’ carbon emissions and environmental transparency, based on individual stock returns. We estimate an asset pricing model with time-varying risk premia, where the greenium is associated with a priced...

The paper investigates the determinants of the idiosyncratic volatility puzzle by allowing linkages across asset returns. The first contribution of the paper is to show that portfolios sorted by increasing indegree computed on the network based on Granger causality test have lower expected...

This paper studies the evolution of the greenium, i.e. a risk premium linked to firms' greenness and environmental transparency, based on individual stock returns. We estimate an asset pricing model with time-varying risk premia, where the greenium is associated to a priced 'greenness and...

This study provides evidence on the existence of a negative Greenium, i.e. a risk premium linked to firms' greenness and environmental transparency, based on European individual stock returns. We define a priced ‘greenness and transparency' factor based on companies' greenhouse gas emissions...
