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.

Sparse High-Dimensional Vector Autoregressive Bootstrap

no code implementations2 Feb 2023 Robert Adamek, Stephan Smeekes, Ines Wilms

We introduce a high-dimensional multiplier bootstrap for time series data based capturing dependence through a sparsely estimated vector autoregressive model.

Local Projection Inference in High Dimensions

no code implementations7 Sep 2022 Robert Adamek, Stephan Smeekes, Ines Wilms

In this paper, we estimate impulse responses by local projections in high-dimensional settings.

Min(d)ing the President: A text analytic approach to measuring tax news

no code implementations7 Apr 2021 Adam Jassem, Lenard Lieb, Rui Jorge Almeida, Nalan Baştürk, Stephan Smeekes

We propose a novel text-analytic approach for incorporating textual information into structural economic models and apply this to study the effects of tax news.

A dynamic factor model approach to incorporate Big Data in state space models for official statistics

1 code implementation31 Jan 2019 Caterina Schiavoni, Franz Palm, Stephan Smeekes, Jan van den Brakel

In this paper we consider estimation of unobserved components in state space models using a dynamic factor approach to incorporate auxiliary information from high-dimensional data sources.

A Residual Bootstrap for Conditional Value-at-Risk

no code implementations28 Aug 2018 Eric Beutner, Alexander Heinemann, Stephan Smeekes

A fixed-design residual bootstrap method is proposed for the two-step estimator of Francq and Zako\"ian (2015) associated with the conditional Value-at-Risk.
