I work on the problem of dynamic scoring a la Leeper and Yang (2008) for the Tunisian economy.
how i can calculate a new steady state after a (-1%) tax shock with dynare and does it give the same result by solving the system with fsolve from Matlab (by doing this shock manually).
The problem is how can i detremine the dynamics of transition.
You can try to use Dynare’s
steady-command, but I can only recommend computing it manually. Also, what you describe sounds like a normal perfect foresight transition experiment.
