SVAR causal interpretation: shock effects vs effects between variables

Consider a structural vector autoregressive (SVAR) model. One way to define a SVAR model is $$ \begin{aligned} B_0 y_t = B_1 y_{t-1} + \cdots + B_p y_{t-p} + \omega_t \quad (1) \ , \end{aligned} $$ ...

Cholesky Identification in Structural VAR

Can you suggest me a framework in macroeconomics or finance where identification of a Structural VAR model through Cholesky ordering is still considered credible (in your opinion)? I'm looking for a ...

Can I test the impulse response function only for the variables which are Granger cause?

I have a VAR(1) model with 10 variables. I want to check what is Granger causality and examine impulse response function. Let's say that I have equation for variable Y, X is a Granger cause for Y, Z ...

I am replicating a paper using BVAR model and I first I have run the model with non-stationary data. Then I just wanted to compare the results with stationary data and I launched the model but I get ...

How to estimate a non-resursive SVAR in Eviews/Stata?

I came across this text that seems to estimate a non-recursive SVAR in Eviews, but the restrictions are kinda different from what I expected. In their recursive SVAR, they have the following results ...

Can a subset of variables in a lower triangular Cholesky identification scheme be ordered arbitrarily if we do not care about their shocks?

For example, in a three-variable SVAR model in Favero, C. A. (2001), the author uses Cholesky decomposition to identify only money shocks by ordering it last. Thus, both $p_t$ and $y_t$ affect $m_t$ ...

what is the Intuition behind Cholesky identification in VAR/SVAR

In my understanding of Cholesky identification, $RF$ in the model below should be ordered last since it is contemporaneously affected by all variables in the model. So why does Leeper EM, Sims CA, Zha ...
