Financial Instability and Optimal Monetary Policy Rule

Abstract

This paper investigates the effect of financial instability on the design of monetary policy rule for a small open economy. We find evidence that optimal monetary policy rule reacts directly to financial imbalances and, as a result, to the real exchange rate movements. However, optimal rule would not react to the real exchange rate changes directly if central bank does not care about the financial instability. For a quantitative analysis, impulse responses of some macroeconomic variables and financial instability to the domestic productivity and foreign country output shocks, resulting from simulation, are also analysed in this paper.Financial instability, Optimal monetary policy rule, Real exchange rate, Open economy
