  This paper analyzes identification issues of a behavorial New Keynesian model
and estimates it using likelihood-based and limited-information methods with
identification-robust confidence sets. The model presents some of the same
difficulties that exist in simple benchmark DSGE models, but the analytical
solution is able to indicate in what conditions the cognitive discounting
parameter (attention to the future) can be identified and the robust estimation
methods is able to confirm its importance for explaining the proposed
behavioral model.
