This paper provides novel insights into the dynamic properties of variance and semivariance premia. Considering nine international stock market indices, we find consistent evidence of significantly negative total and downside (semi)variance premia of around -15 bps per month. These premia almost...

Climate change is real and dangerous. Exactly how bad it will get, however, is uncertain. Uncertainty is particularly relevant for estimates of one of the key parameters: equilibrium climate sensitivity--how eventual temperatures will react as atmospheric carbon dioxide concentrations double....
