Dear Feifer, I have a question on your github codes which involves with the steady state price on Gali(2015) nonlinear model

General DSGE Modeling Replication Attempts

I try to replicate your codes in the web below and find I cannot solve for the steady state of price. When writing the models by steady state notations, price§ will just disappear. I will appreciate if you tell me how to get the steady state price.

The New Keynesian model features price level indeterminacy. Any price level will be a steady state. Only inflation and relative price changes are uniquely determined. Usually, people set the steady state price level to 1, i.e. pick one convenient value.
