estimating the memory parameter can avoid bias incurred by misspecification of the short memory component. We introduce a broad … to a smooth interpolation of asymptotic variances. The bias of these two estimates also differs to higher order, and we … also show how bias, and asymptotic mean square error, can be reduced, across the class of estimates studied, by means of a …

This paper explores the potential for violations of VaR subadditivity both theoretically and by simulations, and finds that for most practical applications VaR is subadditive. Hence, there is no reason to choose a more complicated risk measure than VaR, solely for reasons of coherence.
