Monetary Policy, Liquidity Stress And Learning Dynamics
This paper examines the interactions between monetary policy and stability of interbank money markets. After showing some empirical evidence of a central bank's concern for money market stability, the author derives a forward smoothing interest rate rule moving from an explicit target in terms of a liquidity stress indicator. The implications of this approach on equilibrium determinacy and learnability are analyzed. The author shows that equilibrium uniqueness is not necessarily compatible with equilibrium learnability, and learnability, in general, has tighter requirements than determinacy.
