I don’t know how to proceed and don’t know what to do from here. Please help. I use macbook and am able to run my lecturers tute so am not sure if it’s something to do with installation or it’s just my mod file.
Hi jpfeifer,
I managed to work around the above problem and after I have worked around it and adjusted a few things in the model, I now have an error of “Matrix is singular to working precision”. Please find below my mod file.
I always appreciate your assistance and time and hoping to get assisted.

You say your model is linear. In this case, all steady states are . But using 0 as the steady state, equations 9 and 10 do not solve. Consequently, there is a mistake in those equations (unless they are still linear and the constant part is not 0)
