Shocks in VAR(2) form

Stochastic simulations
1

Hello,

I have a query regarding the specification of shocks in the Model.

Instead of AR(1) process for each of the three foreign variables in my model, I would like to specify VAR(2) path for my three foreign variables (see the below excerpt from Justiniano Presto (2010).

How do I specify this under the model block in dynare?
In the below example for bvar, dx and dy are written as AR(1) under the model block.

How can i write it as VAR(2)
Best,

Simply write the VAR in the model block. See the exogenous process in

Thank you Prof Pfeifer for the reference. This is very helpful.

Many Thanks
