Hi everyone,

I have a problem with my mod file to be read by version 4.1.3. In particular, the message is “syntax error, unexpected INF_CONSTANT. DYNARE: preprocessing failed”. I don’t know what INF_CONSTANT actually means? I’ve checked my settings of parameters and made sure that there is no constant in the model since it is log-linearized. The interesting thing is that when I run the same mod file in version 3.065 I get an error “In an assignment A(I) = B, the number of elements in B and I must be the same”, the meaning of which I don’t know either. Perhaps, it is related to the rank condition. I want to produce impulse response functions using stochastic simulation with the options steady and check.

If anybody can guide me through these, I would be very happy.

Thanks in advance.
