Hey Johannes!
I was thinking about how Dynare could play a role in implementing transition dynamics in models with unbalanced growth. Are you aware of any ways to trick dynare into solving a problem where, say, there's balanced growth in the long "long" run, but unbalanced growth in the short run? My impression is that one would want to make use of the initval endval block sections. An alternative is using dynare as part of a shooting algorithm. I looked for prior posts about this topic, but found none.
Any thoughts?
