I’m trying to modify the model by [Abadi et al. (2023)](https://www.aeaweb.org/articles?id=10.1257/aer.20190150).

My idea is to remove the different firms and introduce to different banks.

The mod file “OneFirm” works nicely. The mod file “TwoBanksModel” breaks down saying

"Error using print\_info (line 33)  
The steadystate file did not compute the steady state

Error in stoch\_simul (line 119)  
print\_info(info, options\_.noprint, options\_);  
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^  
Error in TwoBanksModel.driver (line 1552)  
[info, oo\_, options\_, M\_] = stoch\_simul(M\_, options\_, oo\_, var\_list\_);  
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^  
Error in dynare (line 306)  
evalin(‘base’,[fname ‘.driver’]);  
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^”

Use

```auto
resid(non_zero);

```

to see

> Residuals of the static equations:  
> Equation number 29: Eq\_B\_1 : 0.009844  
> Equation number 44: Eq\_B\_2 : -0.009844

That must be the mistake.
