Analysis Of The Monetarist High Powered Money Multiplier Determines Movements Of The Money Supply

Decent Essays

1. Introduction
The monetarist high-powered money multiplier determines movements of the money supply (MS) into the multiplier and high-powered money (H). The model explains how central bank policy actions influence the money stock (Garfinkel and Thornton, 1991), which reflects changes in high-powered money. This paper aims to explain the limitations of the money multiplier and account for its limitations by assessing alternative theories, whilst placing the model in a current context.
2. Theory
The model holds a rather stable ratio between H, that is, the demand for money in circulation plus banks reserves, M0, and the stock of money, M1. These are equal to the MS, which is the amount of notes and coins held by the public and deposits, M2.
The monetary base consists of central bank liabilities, so that central bank intervention on M0 generates a multiplied effect on M2. Hence, the money multiplier shows the relation of the monetary base and the MS (M2). Advantageously, the theory holds that central banks intervene through controlling the quantity of reserves that multiply up to a greater change in bank loans and deposits so that money growth is consistent with its objectives of stable inflation. By doing so, central banks bring about a desired short-term interest rate. Central banks take policy action through controlling reserve quantities. Central banks, however, actually set the cost of borrowing, not the quantity, as there is no other way for the system to be controlled
