Previous studies suggested Monetary Conditions Index (hereafter MCI)
serves as an indicator of the monetary policy stance to capture the
degree of tightness of the monetary policy. The weights of the MCI in
the model reflect long-term effects of the interest rate and the
exchange rate on the economic activity. Nevertheless, MCIs may not be
used as an operational target as it is not resilient to shock
identification. Recognizing the caveats upon its usage empirically, the
augmented MCI (AMCI) is contemplated by incorporating other informative
variables into the conventional model. Since monetary policy affects the
price level through a number of transmission mechanisms, other variables
need to be incorporated to AMCI to account for possible channels in the
transmission mechanisms. First, the weight of the AMCI is estimated, and
the lag effect on the real GDP is identified using Autoregression
Distribution Lags (ARDL) approach. Bounds test reveals evidence of
cointegration for ASEAN-Five countries. Results reveal that AMCI tracks
the inverse movements of the real GDP plausibly well on average, except
during the onset of 1997/98 Asian Financial Crisis.
