I received the following message after running the Dynare. What is the reason?

Output argument “bnds” (and maybe others) not assigned during call to “mu”.

Error in Sentiment2_steadystate (line 41)

mc=(phi*(PI^(1-(chi*mu))-1) PI^(1-(chimu))*(1-betta)+theta-1)/theta;

You only give a single equation from your model… But I have the impression that mu is also the name of an existing Matlab function. To check that you can look at the output of:

```
>> which mu
```

if the command returns something, it means that you will have to rename your parameter (or variable I do not know).

Best,

Stéphane.

That is a problem with Matlab’s way of functions working. You can circumvent it by either renaming `mu`

or adding

```
mu=0
```

before the loop that extracts the parameter values in the steady state file.
