Hi all, I am working on a model with trend and with 3 inputs Cobb Douglas production function in the form Yt = at* Kt^alpha * (Xt-1ht)^1-alpha * Bt^theta. I couldn’t transform the production side of the model to stationary form. If there is any solution suggestion I would be glad. Thanks very much.
What exactly is your problem? You did not even describe which variable has a trend and whether the Cobb-Douglas function is constant returns to scale?
Hi again Prof. Pfeifer, sorry for my inadequate description. I am trying to extent Garcia-Cicco et al (2010) model. Firstly, I would like to decompose external borrowing as FDI and FPI and introduce capital controls on FPI as in (Olanı, 2017). When I run the model without stating FDI (f) as a predetermined variable it works fine however when I set f as a predetermined variable I got the following error:

What might be the problem?
Secondly, in the second mod file I tried to add the FDI into the production function. However, in resource constraint equation there seems to be an error. Any ideas about what am I doing wrong? Thanks…

- You need to check your timing assumptions. It seems strange that the return on FDI next period is not stochastic.
- For the second file, it seems strange that
rf=-0.1531
in your steady state file.
