Keynes's Approach to Money: An Assessment After Seventy Years

This paper first examines two approaches to money adopted by Keynes in the General Theory. The first is the more familiar ‘supply and demand’ equilibrium approach of Chapter 13 incorporated within conventional macroeconomics textbooks. Indeed, even Post Keynesians utilizing Keynes's ‘finance motive’ or the ‘horizontal’ money supply curve adopt similar methodology. The second approach of the General Theory is presented in Chapter 17, where Keynes drops ‘money supply and demand’ in favor of a liquidity preference approach to asset prices that offers a more satisfactory treatment of money's role in constraining effective demand. In the penultimate section, I return to Keynes's earlier work in the Treatise on Money as well as the early drafts of the General Theory to obtain a better understanding of the nature of money. I conclude with policy implications.     

DEMAND FOR MONEY AND EXPENDITURE COMPONENTS IN SOUTH AFRICA: ASSESSMENT FROM UNRESTRICTED ERROR-CORRECTION MODELS

The main aim of this study is to examine empirically the long‐run relationship of money demand and its determinants in South Africa. In contrast with existing studies on the subject, the present study considers various components of real income as determinants. The disaggregated components are final consumption expenditure, expenditure on investment goods and exports. The other determinants are domestic interest rate, yield on government bonds and the exchange rate. The results confirm that the different components of real income have different impacts on the demand for money in South Africa. The presence of long‐run equilibrium relationships between the demand for real M1, M2 and M3 and their determinants is confirmed based on the results of bounds testing.     

A STOCHASTIC ESTIMATION FRAMEWORK FOR COMPONENTS OF THE SOUTH AFRICAN CONSUMER PRICE INDEX

Under inflation targeting in South Africa, it is important to monitor and forecast changes in prices, not only for aggregate measures of the consumer price index, but also its underlying sub-components. Hypotheses about sectoral transmission of policy and shocks are often more specific than hypotheses about overall transmission. This study employs a stochastic framework to estimate richly specified equilibrium correction models, four-quarters-ahead, for the 10 sub-components of the first targeted measure of the consumer price index, CPIX. The stochastic trends are estimated by the Kalman filter, and interpreted as capturing structural breaks and institutional change, a frequent cause of forecast failure. The trends suggest the design of deterministic split trends for use in recursive forecasting models, towards more accurate overall inflation forecasting. This research also has practical use for monetary policy in allowing identification of sectoral sources of inflation.     

The stability of money demand in Germany and in the EMS: Impact of German unification

The Stability of Narrow Money Demand in Germany and Aggregate Money Demand in the EMS: Impact of German Unification. —This paper shows that the German monetary union not only had an impact on the stability of the narrow money demand in Germany but also on the stability of the aggregate demand for money in two larger European currency areas, consisting of three and seven EMS countries. However, the impact was only of a temporary nature. The empirical results show that the close link between real money, output, and the interest rate still exists. In a European Monetary Union, narrow money thus remains a potential candidate as an indicator and/or intermediate target for the European Central Bank.     

ARE AFRICAN CENTRAL BANKS SUFFICIENTLY INDEPENDENT FOR MONETARY CONVERGENCE?

Central bank independence (CBI) is currently a widely debated and topical issue commanding the centre point of many economical and political debates, filling the pages of many scholarly journals. Both central bank independence and accountability are currently regarded as necessary best practices for achieving price stability. The importance of CBI rests on the premise that inflation is primarily a monetary phenomenon, and that the cost of reducing inflation can be lowered by an independent central bank with credibility. Support for CBI also stems from the argument that the power to create money should generally be separated from the power to spend it. This is even more relevant for countries with weak political institutions. However, various studies (cited below) detected lower inflation in those countries where independence of their central banks is the strongest. Countries all over – including some on the African continent – have increased the independence of their central banks accordingly.     

The exchange rate and monetary conditions in the Euro area

The Exchange Rate and Monetary Conditions in the Euro Area. — Using information from a variety of sources, this paper suggests that the exchange rate will play an important role in the transmission of the impact of monetary policy on the real economy and inflation in the euro area. As a first approximation it would be reasonable to assume that an increase in the real 90-day interest rate of 100 basis points would have the same effect on demand two years later as a 3.5 percent fall in the real euro exchange rate. This implies that the euro area will tend to behave like a large open economy rather than a closed economy and hence that it would be helpful in informing monetary policy to construct a Monetary Conditions Index (MCI).     

The effects of reconstruction finance corporation assistance on Michigan's banks' survival in the 1930s

We examine the effects of the Reconstruction Finance Corporation's (RFC) loan and preferred stock programs on bank failure rates in Michigan during the period 1932–1934, which includes the important Michigan banking crisis of early 1933 and its aftermath. Using a new database on Michigan banks, we employ probit and survival duration analysis to examine the effectiveness of the RFC's loan program (the policy tool employed before March 1933) and the RFC's preferred stock purchases (the policy tool employed after March 1933) on bank failure rates.     

A nonnormative theory of inflation and central bank independence

A Nonnormative Theory of Inflation and Central Bank Independence. — The authors study monetary policy under different central bank constitutions when the labor-market insiders set the minimal wage so that the outsiders are involuntarily unemployed. If the insiders are in the majority, the representative insider will be the median voter. The authors show that an independent central bank, if controlled by the median voter, does not produce a systematic inflation bias, albeit equilibrium employment is too low from a social welfare point of view. A dependent central bank, in contrast, is forced by the government to collect seigniorage and to take the government’s re-election prospects into account. The predictions of their theory are consistent with the evidence that central bank independence decreases average inflation and inflation variability, but does not affect employment variability.     

INTERNATIONAL LESSONS FOR THE PROPERTY PRICE BOOM IN SOUTH AFRICA

South Africa appears to share some of the characteristics (property price boom, easing of monetary policy, strong domestic demand growth) of asset price booms in industrial countries that were followed by a period of weak growth. The international experience suggests that a number of practical obstacles need to be overcome before a more proactive role for monetary policy is warranted. However, a larger variety of available mortgage contracts, including longer‐term fixed‐rate contracts, should allow for a more efficient allocation of interest rate risks. Also, a more systematic nationwide collection of property price data, including data on commercial property price developments, would provide a more representative basis for analysis.
