3rd order solution problems

Dear All,
I am able to solve the attached model for order 1 and 2 but I am getting the following error

The parameters vector contains NaN or Inf

When I try order equal to 3.

Many thanks in advance for your time and help.

Delete ckappa from the parameter definition:

Warning: Some of the parameters have no value (ckappa) when using stoch_simul. If these parameters are not initialized in
a steadystate file or a steady_state_model-block, Dynare may not be able to solve the model…

At third order, we do not allow any NaN parameters as they may crash Matlab.

Dear Johannes,
Many thanks for your prompt reply. This is deeply appreciated!
I wish you and your colleagues a very happy and prosperous New Year!
