Money,Interest Rate and Foreign Exchange Rate As Indicator Variables Of Monetary Policy

Since monetary policy operations affect the ultimate targets such as real income and prices with considerable time lags, this papers attempts to identify the indicator variable of monetary policy in Korea by using autoregression tests, variance docompositions of VAR forecasts and cointegration analyses. The results show that in Korea unlike the U.S., a broad concept of money, interest rate and foreign exchange rate, taken together, could serve as the indicator variables. In particular, M3, But not M2 nor MCT, is significantly related to real income both in the short-run and in the long-run. Such a finding rejects the practice of controlling either M2 or MCT which the Korean monetary authority had exercised before implementing the recent IMF financial-reform program. E5]
