Robust inference intime-varying structural VAR models : the DC-Cholesky multivariate stochasticvolatility model
Hartwig, Benny - 2020
This paper investigates how the ordering of variables affects properties of the time-varying covariance matrix in the Cholesky multivariate stochastic volatility model.It establishes that systematically different dynamic restrictions are imposed whenthe ratio of volatilities is time-varying....

Identification of one independent shock in structural VARs
Fiorentini, Gabriele; Moneta, Alessio; Papagni, Francesca - 2024
We establish the identification of a specific shock in a structural vector autoregressive model under the assumption … that this shock is independent of the other shocks in the system, without requiring the latter shocks to be mutually … independent, unlike the typical assumptions in the independent component analysis literature. The shock of interest can be either …

On the long-run neutrality of demand shocks
Chen, Wenjuan; Netsunajev, Aleksei - 2015
Long run neutrality restrictions have been widely used to identify structural shocks in VAR models. This paper revisits the seminal paper by Blanchard and Quah (1989), and investigates their identification scheme. We use structural VAR models with smoothly changing covariances for identification...

State-space cointegration modeling for the analysis of exogenous shocks to prices in Israeli-Palestinian food trade
Ihle, Rico; Götz, Linde Johanna; Rubin, Ofir D. - 2011
The Israeli-Palestinian conflict constitutes a prominent example of a long-lasting political conflict which has major consequences for the livelihoods of the people on both sides. The agricultural sectors of the Palestinian and Israeli economies are tightly connected. However, various security...

Symmetry and separability in two-country cointegrated VAR models : representation and testing
Krolzig, Hans-Martin; Heinlein, Reinhold - 2013
Introducing the approach by Masanao Aoki (1981) to time series econometrics, we show that the dynamics of symmetric linear possibly cointegrated two-country VAR models can be separated into two autonomous subsystems: the country averages and country differences, where the latter includes the...

Estimation of Structural Impulse Responses : Short-Run Versus Long-Run Identifying Restrictions
Lütkepohl, Helmut - 2017
There is evidence that estimates of long-run impulse responses of structural vector autoregressive (VAR) models based on long-run identifying restrictions may not be very accurate. This finding suggests that using short-run identifying restrictions may be preferable. We compare structural VAR...

On Time-Varying VAR Models : Estimation, Testing and Impulse Response Analysis
Yan, Yayi; Gao, Jiti; Peng, Bin - 2021
Vector autoregressive (VAR) models are widely used in practical studies, e.g., forecasting, modelling policy transmission mechanism, and measuring connection of economic agents. To better capture the dynamics, this paper introduces a new class of time-varying VAR models in which the coefficients...
