Hi everyone,

I used the model by Adam [2011] Government debt and optimal monetary and fiscal policy. I want to study the dynamics if government spending is fixed from period 20 on, so basically I start in one steady state and I want to see the transition to the new steady state with lower government spending using the extended path algorithm. However, I am struggling writing this down…any suggestions? The FOCs are different for t\<=20 and for t \> 20. But how do I solve that using Dynare?

Any help appreciated! Best,  
Peter
