Hi Tom!!!

I'm replicating Mountford and Uhlig (2009)(MU) by adding an oil shock to the system. Need your kind help in figuring out the error in my codes in the attached.
I am running the MU without delay shocks, but I am getting the error:

## MAT14. Non-invertible Matrix. Using Generalized Inverse for SYMMETRIC.
The Error Occurred At Location 851, Line 52 of FORCEDFACTOR
Called From Location 514, Line 32 of loop/block

What could be wrong?

best regards

You shouldn't put the NOPRINT option on the ESTIMATE until you know it's right. For some reason your RBPEXP and GVA series are identical, so the covariance matrix is deficient rank.
