I have two questions here, thank you for the help.
If I would like to get % deviation from the steady state, should I write the model as exp (x), or exp (xx)?
Also, if one of the variable name is tauc, will it be readable if I write exp (tauctauc)?
If I want to get solution of % deviation from the steady state, should I take log to all the original steady state so the Dynare will evaluate the log variable around the natural log of steady state, as Stephanie Schmitt-Grohe and Martin Uribe (2004) Matlab code did?
Thank you again for the reply.
