Parameters must have same value in both states #151

Closed VanessaKunzmann closed 2 years ago

VanessaKunzmann commented 3 years ago

I am working on a regime switching DSGE model and face the problem that my model only solves whenever I give the policy parameters the same value in both states/regimes. Thereby it does not matter what values as long as they are the same.

What could be the reason for this? Thank you very much!

Hi,

It could be anything including the structure of the transition probabilities.

It is impossible for me to tell you what the problem is without seeing the model.

Cheers

Hi, thanks for the quick response. Attached is my Model. I am working on a Two Country DSGE Model with Fiscal Regime Switching in both countries. The model has a similar setup as in Rabanal (2009). Rab_open2states.zip

I would really appreciate if you can find anything that causes this problem. Thank you in advance!

What should I run to replicate the problem you are having?

If you run run2states.m it is currently running through because all policy coefficients have the same values in each state (but I need different coefficients in each state) but as soon as I change just one number it is not working any more.

line 203-208: This is working: phi_b(a,1),-0.0122; phi_b(a,2),-0.0122; phi_g(a,1), 0.5172; phi_g(a,2), 0.5172; phi_y(a,1), 0.2025; phi_y(a,2), 0.2025;

This is not: phi_b(a,1),-0.0122; phi_b(a,2),-0.0122; phi_g(a,1), 0.5172; phi_g(a,2), 0.5172; phi_y(a,1), 0.2025; phi_y(a,2), 0.2026; <-- just one integer differs

Is this understandable?
