Variance decomposition under SVAR
Posted: Sun Oct 01, 2017 6:16 am
Hi,
I am using real GDP of US and India to represent Global and Regional outputs respectively along with GDP of other six SAARC countries. The long run restrictions on SVAR is imposed following Blanchard & Quah (1989) procedure. Accordingly, it is assumed that in the long run the shock in the output of each of the SAARC countries will not affect both regional and global outputs and similarly, the shock in regional output (as represented by India) will not affect global output but will affect the output of other member countries. Now adopting Chow & Kim (2003) procedure, we shall decompose variability of domestic output into domestic, regional and global output shocks in the context of estimating optimum currency area (OCA) in South Asia. The idea is that if the countries in the region face higher degree of regional shock compared to country specific shock, they are considered to be better choice for common currency. Kindly advise how to perform variance decomposition under SVAR using the above case as an example given that the variance decomposition command in the eviews doesn't differentiate results between SVAR and simple VAR navigation...
I am using Eviews 9.0. I have enclosed my eviews file and a paper using aforementioned model for your ready reference.
