Is inflation always a monetary phenomenon in Malaysia?

The purpose of this study is to empirically re-investigate the money-prices nexus for Malaysia through the cointegration and causality techniques. This study covered the monthly data from 1971:01 to 2008:03. The Johansen cointegration test suggests that the variables are cointegrated. Furthermore, the MWALD test shows a unidirectional causal relationship run from money supply (M2) to aggregate prices, meaning that only the monetarist’s view exist in the Malaysian economy. However, the time-varying causality tests indicate that inflation is not always a monetary phenomenon in Malaysia. Therefore, the contractionary monetary policy may not an effective instrument in managing inflationary behaviour in Malaysia.
