This paper examines the impact of real time uncertainty on the performance of international mean-variance conditional asset allocation. This notion can be defined as the uncertainty faced by an investor regarding specification choices necessary to implement a conditional strategy. To assess the...

We consider a nonparametric method to estimate conditional expected shortfalls, i.e. conditional expected losses knowing that losses are larger than a given loss quantile. We derive the asymptotic properties of kernal estimators of conditional expected shortfalls in the context of a stationary...

We consider a nonparametric method to estimate copulas, i.e. functions linking joint distributions to their univariate margins. We derive the asymptotic properties of kernel estimators of copulas and their derivatives in the context of a multivariate stationary process satisfactory strong mixing...
