White et al. (2015) extend the vector autoregressive (VAR) for conditional mean to VAR for conditional quantiles (VAR-VaR) to capture the interdependencies among the quantiles of multiple time series. In this paper, we introduce a post-lasso estimator to extend VAR-VaR to the high-dimensional...

This paper proposes a simple, fairly general, test for global identification of unconditional moment restrictions implied from point-identified conditional moment restrictions. The test is based on the Hausdorff distance between an estimator that is consistent even under global identification...

This article proposes omnibus specification tests of parametric dynamic quantile regression models. Contrary to the existing procedures, we allow for a flexible and general specification framework where a possibly continuum of quantiles are simultaneously specified. This is the case for many...

Historical Simulation (HS) and its variant, the Filtered Historical Simulation (FHS), are the most widely used Value-at-Risk forecast methods at commercial banks. These forecast methods are traditionally evaluated by means of the unconditional backtest. This paper formally shows that the...
