Global bank network connectedness revisited: What is common, idiosyncratic and when?

no code implementations4 Feb 2024 Jonas Krampe, Luca Margaritella

This allows to disentangle: (I) the part of system-wide connectedness (SWC) due to the common component shocks (what we call the "banking market"), and (II) the part due to the idiosyncratic shocks (the single banks).

High-Dimensional Causality for Climatic Attribution

no code implementations8 Feb 2023 Marina Friedrich, Luca Margaritella, Stephan Smeekes

In this paper we test for Granger causality in high-dimensional vector autoregressive models (VARs) to disentangle and interpret the complex causal chains linking radiative forcings and global temperatures.

Inference in Non-stationary High-Dimensional VARs

no code implementations2 Feb 2023 Alain Hecq, Luca Margaritella, Stephan Smeekes

We combine this lag augmentation with a post-double-selection procedure in which a set of initial penalized regressions is performed to select the relevant variables for both the Granger causing and caused variables.
