Dynare forums

Hi,

I just started using dynare. I wrote a fairly simple dynamic investment model (attached). I can get Dynare to compute a steady state, but when I try to simulate the model, I get the "Index exceeds matrix dimensions" error. This is puzzling to me, given that the steady state simulation works. Any suggestions? The full error is below.
Thanks for your help!

Index exceeds matrix dimensions.

Hi,

when I run your mod-file I get a message informing you that Dynare can't compute deterministic simulation for purely backward models (I use the latest version of Dynare -FI this message has been added recently)

Weird. I just downloaded dynare today (4.1.2), so I'm not sure why I wouldn't get that that message as well.

sorry I was talking about the unstable version of dynare

Your model is purely static: no forward and no backward variable. Dynare is not designed to solve such static systems. You can use a vanilla non-linear solver to do that.

Best,
