What is steady state learning in the context of boundedly rational expectation modeling? E.g. see Evans et al. (2009)
They define it as: "Under steady-state learning, agents use past data to ...

determinacy vs. indeterminacy of equilibria in dynamic systems
As explained in Hommes (2018), equilibria in dynamic systems, like DSGE models, can either be determinate or indeterminate. A REE (rational expectations equilibrium) is determinate when there exists a ...
