simulating around the stochastic steady state in dynare

[sudiptokarmakar2004]

I have a model of occasionally binding capital requirement constraints for banks. The goal is to simulate the economy around the stochastic steady state. All the dynare documentation that I have been looking at seems to suggest that this is not possible in dynare. Just wanted to make sure if I am misunderstanding it. I do observe that in the dynare output there is a vector called means of the endo variables. I am not sure if these values correspond to the ergodic distribution. Any leads in this regard will be highly appreciated. Thanks a lot.

What do you mean with

simulate the economy around the stochastic steady state

? Do you want to compute the decision rules at the stochastic steady state? And when you say stochastic steady state, do you really mean the stochastic steady state (ergodic mean in the absence of shocks) or the ergodic mean?
Note also that Dynare cannot handle occasionally binding constraints in a stochastic context.

Thanks for the reply. Ok so let me be a bit mor specific. So I approximate the occasionally binding constraint with a penalty function and so then dynare can handle this. Now in terms of the model, my bank in the steady state has a 1% capital buffer but in this environment it is completely aware that future shocks may happen. So when I say I want to simulate around the stochastic steady state, I mean starting from this point, I would like to look at irfs following the realization of some bank net worth shocks. A more basic question is I am not sure how to implement this in dynare.

[sudiptokarmakar2004]

What I mean is I can compute the deterministic SS where capital buffer is = 0. And then then I can look at decision rules, irfs etc in response to some shocks. Here I can simply enter these numbers in the initval block. The problem is I am not sure how to do the same things, starting from the stochastic SS in dyanre. Thanks a lot for the help.

[sudiptokarmakar2004]

Specifically answering your question, I mean the stochastic SS in the sense that there is no shock today but might occur in the future. Yes, I want to compute the decision rules at the this stochastic steady state. Thanks

Computing decision rules at the stochastic steady state is not supported. But you can easily generate IRFs starting at the stochastic steady state. Code for this is available in the replication files to Born/Pfeifer (2014): "Risk Matters: A comment" at https://www.aeaweb.org/articles.php?doi=10.1257/aer.104.12.4231.
