Quantile forecasting has become an important research topic in econometrics as policy makers and investors are … a novel methodology for out-of-sample quantile forecasting with textual data. It relies on elastic net quantile … regression to incorporate "attention" into the quantile forecasting model, allowing for the dictionary to vary over time and …

We extend recurrent neural networks to include several flexible timescales for each dimension of their output, which mechanically improves their abilities to account for processes with long memory or with highly disparate time scales. We compare the ability of vanilla and extended long short...

Closed-end fund (CEF) prices often exhibit large and persistent deviations from their associated net asset values (NAVs), which is puzzling considering that NAVs are publicly observable for CEFs, which essentially represent repackaged financial assets. The persistence of these deviations is...
