A question about variance decomposition

hello! I use “moments_varendo” to get the variance decomposition,

but I get a strange value for example the sum of the posterior variance decomposition of output

not equal one, and for consumption the sum is much smaller than one. It means I get wrong in model?

Thanks for help!

Best Regards YOYO

Could anyone give me some suggestion?

I really scared that my model is all wrong…

Best Regards YOYO
