Post Keynesian monetary theory and its implications for monetary policy in South Africa

The theoretical foundations of the Post Keynesian view of money are examined, including the nature of money, role of uncertainty and time, and the use of equilibrium concepts. This provides a backdrop against which the Post Keynesian analysis of interest rates, investment behaviour: inflation and demand determination is presented in a framework of non-neutral money and Keynes' principle of effective demand. A model of the Post Keynesian theory of money is presented, with arguments as to why the IS/LM model of the neoclassical synthesis is considered deficient. The money supply endogeneity view is explored, together with Keynes' finance motive. The open economy case is considered, with emphasis on a small open economy. The monetary policy perspectives of the Post Keynesian camp are examined. The implications for South Africa are considered in respect of money supply targeting, interest rate policy, anti-inflation measures, public debt management, exchange rates and Reserve Bank objectives.EconomicsM.A. (Economics
