BK conditions are not satisfied in the model containing shadow banks

[jpfeifer]

The steady state contains NaN or Inf - Estimation Error

Before moving to estimation, make sure a calibrated version of the model solves. See Remark 2 (Using stoch_simul before Estimation) Remark 15 (initval vs. steady_state_model vs. steadystate-file) in Pfeifer (2013): “A Guide to Specifying Observation Equations for the Estimation of DSGE Models”

Also, it is generally not a good idea to start with a very complication model. Debugging it is like searching for a needle in a haystack. Try simplifying the model and then adding back features.
