As traditional monetarists Market Monetarists see money as being at the centre of macroeconomic discussion. To us both inflation and recessions are monetary phenomena. If central banks print too much money we get inflation and if they print to little money we get recession or even depression.
This is often at the centre of the arguments made by Market Monetarists. However, we are exactly Market Monetarists because we have a broader view of monetary policy than traditional monetarists. We deeply believe in markets as the best “information system” – also about the stance of monetary policy. Even though we certainly do not disregard the value of studying monetary supply numbers we believe that the best indicator(s) of monetary policy stance is market pricing in currency markets, commodity markets, fixed income markets and equity markets. Hence, we believe in a Market Approach to monetary policy in the tradition of for example of “Manley” Johnson and Robert Keheler.
In fact we want to take out both the “central” and “banking” out of central banking and ideally replace monetary policy makers with the power of the market. Scott Sumner has suggested that the central banks should use NGDP futures in the conduct of monetary policy. In Scott’s set-up monetary policy ideally becomes “endogenous”. I on my part have suggested the use of prediction markets in the conduct of monetary policy.
Sometimes the Market Monetarist position is misunderstood to be a monetary version of (vulgar) discretionary Keynesianism. However, Market Monetarists are advocating the exact opposite thing. We strongly believe that monetary policy should be based on rules rather than discretion. Ideally we would prefer that the money supply was completely market based so that velocity would move inversely to the money supply to ensure a stable NGDP level. See my earlier post “NGDP targeting is not a Keynesian business cycle policy”
Even though Market Monetarists do not necessarily advocate Free Banking there is no doubt that Market Monetarist theory is closely related to the thinking of Free Banking theorist such as George Selgin and I have early argued that NGDP level targeting could be see as “privatisation strategy”. A less ambitious interpretation of Market Monetarism is certainly also possible, but no matter what Market Monetarists stress the importance of markets – both in analysing monetary policy and in the conduct monetary policy.
