Testing the stability of money multupliers for Croatia

This paper analyses the stability of monetary multiplication process in Croatia and its forecasting ability. The money multiplier approach assumes that the monetary authorities are able to control the monetary base through money multipliers by affecting the money supply and the rate of inflation. Thus, by controlling the monetary base, monetary authorities can achieve price stability. For implementing an effective and accurate monetary policy, money multipliers should be stable. The stability of money multipliers implies that different measures of money supply (i.e. different monetary aggregates) and reserve money are stationary or that different measures of money supply and reserve money are cointegrated. Therefore, the purpose of this paper is to test for the stationarity of money multipliers and to determine the long-run relationship between different monetary aggregates and reserve money for Croatia using monthly data in the period from 2011 to 2019 and the bounds testing (ARDL) approach for cointegration. The results of the unit-root tests indicate that money multipliers are nonstationary, therefore unstable and inappropriate for the short-run policy purpose. On the other side, the existence of stable cointegration relationships suggests the validity of the money multiplier model in the long-run
