How do I use variables in steady state in the model?

How do I use variables in steady state in the model?
we say that r at steady state is r = (1/beta)-(1-delta)
What better way to make this in the section model?

If you know how to solve the steady state of all variables in the model analytically, you should use steady_state_model block , instead of initval, to present how you do that. You also put "r = (1/beta)-(1-delta)" there. See more in dynare manual

Hi,

In the model block, if you need the steady state level of a variable x in an equation (for instance in a Taylor rule), you just need to write STEADY_STATE(x).

Best,
Stéphane.

Alternatively, you can use expressions with the #-operator. See https://sites.google.com/site/pfeiferecon/Pfeifer_2013_Observation_Equations.pdf?attredirects=0 for examples of both cases.

Stéphane.

My question was really this.

But, I was doing the way that Johannes suggested. I will try to use the STEADY_STATE(x).

Thank you very much.
