We propose and implement a procedure to optimally hedge climate change risk. First, we construct climate risk indices … climate risk hedge portfolios. The new mimicking portfolio approach is much more efficient than traditional sorting or maximum … delivering markedly higher and statistically significant alphas and betas with the climate risk indices. …

Several Bayesian model combination schemes, including some novel approaches that simultaneously allow for parameter uncertainty, model uncertainty and robust time varying model weights, are compared in terms of forecast accuracy and economic gains using financial and macroeconomic time series....

This paper focuses on portfolio risk forecasting in an asymmetrical framework. Risk is defined by two factors; the … distribution, respectively their joint risk. Statistical analyses state, this model quantifies the distribution tails very … accurately, resulting precise VaR estimates. We also construct minimum-risk portfolios on basis of the volatility forecasts. The …
