| 讲座简介： | We extend Quantile Partial Correlation Regression (QPCR) to high-dimensional time-series settings by establishing selection consistency of QPCR under dependent, heteroskedastic, and potentially unbounded processes. We introduce an EBIC-type tuning criterion that recovers the true quantile model with high probability. Applying QPCR to predict monthly industrial production growth using a large number of macrofinancial predictors, we find that labour-market and financial conditions are the primary drivers of downside growth risk, while there is little predictive content for upside risk. Decomposing downside risk into its individual components, we construct sector-specific indices that predict it, while controlling for information from other sectors, thereby isolating the downside risks emanating from each sector. |
