Taylor rule and euler equation collinear

Hi,

I am trying to solve a DSGE model with central banks digital currency, however the bug is Taylor rule and euler equation collinear with each other, has anyone seen the similar error? I tried replace these with the equations used by Gali but still the same error, may be because of the complexity of the model? Thanks for your support!

You did not provide the external functions to run the code. Most likely the issue is related to:

Attached the external functions, please neglect the solve_steadystate one. As Price level appear in multiple equations, I don’t think I can get rid of Price level as a variable. Can you help me review it? Thank you so much!

  1. I am pretty sure you can get rid of the price level by only using inflation rates and relative prices.
  2. The bigger issue seems to be the timing of the capital stocks that do not conform to Dynare’s timing convention.

Thank you very much! I’ll try
