MONETARY POLICY IN A SMALL OPEN ECONOMY: THE CASE OF MALAYSIA

This paper provides a case study to characterize the monetary policy regime in Malaysia, from a medium‐ and long‐term perspective. Specifically, we ask how the Central Bank of Malaysia, Bank Negara Malaysia (BNM), has structured its monetary policy regime, and how it has conducted monetary and exchange rate policy under the regime. By conducting three empirical analyses, we characterize the monetary and exchange rate policy regime in Malaysia by three intermediate solutions on three vectors: the degree of autonomy in monetary policy, the degree of variability of the exchange rate, and the degree of capital mobility.     

DYNAMIC EFFECTS OF MONETARY POLICY SHOCKS IN MALAWI

This paper sets out to investigate the process through which monetary policy affects economic activity in Malawi. Using innovation accounting in a structural vector autoregressive model, it is established that monetary authorities in Malawi employ hybrid operating procedures and pursue both price stability and high growth and employment objectives. Two operating targets of monetary policy are identified, viz., bank rate and reserve money, and it is demonstrated that the former is a more effective measure of monetary policy than the latter. The study also illustrates that bank lending, exchange rates and aggregate money supply contain important additional information in the transmission process of monetary policy shocks in Malawi. Furthermore, it is shown that the floatation of the Malawi Kwacha in February 1994 had considerable effects on the country's monetary transmission process. In the post‐1994 period, the role of exchange rates became more conspicuous than before although its impact was weakened, and the importance of aggregate money supply and bank lending in transmitting monetary policy impulses was enhanced. Overall, the monetary transmission process evolved from a weak, blurred process to a somewhat strong, less ambiguous mechanism.     

CREDIT POLICY STRESS IN THE WEST AFRICAN ECONOMIC AND MONETARY UNION

This paper examines credit policy stress in the West African Economic and Monetary Union and provides evidence that a regional credit policy would not suit all the countries that are members of this currency union. Some countries obtain a higher volume of domestic credit when policy is conducted at a domestic level than they would in the context of a single regional policy. Furthermore, there are differences in the country‐specific reaction function to changes in the economic environment. To show the inappropriateness of a regional credit policy within the West African Economic and Monetary Union area, we compute credit stress indicators both for the countries and for the region taken as a whole. The stress indicators represent the gap between the optimal policies conducted at country and regional levels. Our study covers the period from 1980 to 2007.     

THE CYCLICALITY OF MONETARY AND FISCAL POLICY IN SOUTH AFRICA SINCE 1994

This paper uses a structural vector‐autoregression approach to discuss the cyclicality of fiscal and monetary policy in South Africa since 1994. There is substantial South African literature on this topic, but much disagreement remains. Though not undisputed, there is growing consensus that monetary policy has contributed to the remarkable stabilisation of the South African economy over this period. The evaluation of the role of fiscal policy in stabilisation has been less favourable and there is little evidence that a countercyclical fiscal stance was a priority over this period. This paper considers these issues in an empirical framework that addresses some of the shortcomings in the literature. Specifically, it constructs a structural model in contrast with the reduced form models typically used in the South African literature, incorporates the dynamic interaction between monetary and fiscal shocks on the demand side and supply shocks on the other, and avoids controversy over “neutral” base years and the size of fiscal elasticities. The model confirms the consensus on monetary policy, finding it to have been largely countercyclical since 1994. On fiscal policy, this paper finds evidence of pro‐cyclicality, especially in the more recent period, though the policy simulations suggest that the pro‐cyclicality of fiscal policy has had little destabilising impact on real output.     

ASSESSING MONETARY POLICY IN SOUTH AFRICA IN A DATA‐RICH ENVIRONMENT

This paper examines the efficacy of monetary policy in the South African economy using a data‐rich framework. We use the Factor‐Augmented Vector Autoregressive (FAVAR) methodology, which contains 110 monthly variables for the period 1985:02‐2007:11. The results, based on impulse‐response functions, provide no evidence of the price puzzle observed in traditional Structural Vector Autoregressive analysis and confirm that monetary policy in South Africa is effective in stabilising prices. Unlike the traditional vector autoregressive approach, the FAVAR methodology allows further analysis of a large number of variables. Variables from real and financial variables react negatively to a contractionary monetary policy shock. Finally, we find evidence of the importance of a confidence channel transmission following a monetary policy shock.     

ZONE‐TARGETING MONETARY POLICY PREFERENCES AND FINANCIAL MARKET CONDITIONS: A FLEXIBLE NON‐LINEAR POLICY REACTION FUNCTION OF THE SARB MONETARY POLICY

We estimate a flexible model of the monetary policy reaction function of the South African Reserve Bank based on a representation of the policymaker's preferences that capture asymmetries and zone‐targeting behaviours. We augment the analysis to allow for responses to financial market conditions over and above inflation and output stabilisation to address the current debate on the importance of financial asset prices in monetary policy decision making. The empirical results show that the monetary authorities' response to inflation is zone symmetric. Secondly, the monetary authorities' response to output is asymmetric with increased reaction during business cycle downturns relative to upturns. Thirdly, the monetary authorities pay close attention to the financial conditions index by placing an equal weight on financial market booms and recessions.     

ESTIMATING MONETARY POLICY RULES FOR SOUTH AFRICA

The paper combines the estimation of the Monetary Conditions Index (MCI) with the theoretic modelling of optimal monetary policy in South Africa. The idea that monetary policy is not only interested in optimal monetary conditions but also in external stability, provides the basis for the analysis. The paper introduces the concept of the MCI and estimates the relative influence of interest rates and exchange rates on the output gap. The estimated weights are 1.9:1. This estimation results is used to specify operating target rules for South African monetary policy.     

ESTIMATING SARB'S POLICY REACTION RULE

This paper uses a Dynamic Stochastic General Equilibrium (DSGE) model to estimate the South African Reserve Bank's (SARB) policy reaction rule. We find that the SARB has a stable rule very much in line with those estimated for Canada, UK, Australia and New Zealand. Relative to other emerging economies the policy reaction function of the SARB appears to be much more stable with a consistent anti inflation bias, a somewhat larger weight on output and a very low weight on the exchange rate.     

A GROWTH MODEL FOR SOUTH AFRICA

We examine the South African growth experience during 1960‐2005 using an intertemporal growth model. The model combines old growth theory investment dynamics and new growth theory endogenous productivity growth. The consumption and investment decisions are intertemporal and assume open capital markets. Structural change is captured by separating the traded and nontraded sectors, and sectoral productivity growth is determined in a barriers‐to‐growth framework. Calibration of the model shows how the growth experience combines neoclassical convergence, technology spillovers with barriers and productivity‐investment interaction. Counterfactual analysis shows the growth costs of sanctions and protectionism. The suggested model is an alternative to existing growth modelling in South Africa, in which investments are short‐sighted and productivity growth is imposed exogenously.     

MODELLING INFLATION IN SOUTH AFRICA: A MULTIVARIATE COINTEGRATION ANALYSIS

We employ an expectations augmented Phillips curve framework to investigate the link between inflation, unit labour costs, the output gap, the real exchange rate and inflation expectations. Using multivariate cointegration techniques, we find evidence consistent with mark‐up behaviour of output prices over unit labour costs. Most importantly, we find that the mark‐up in the South African economy is much higher than in the U.S. For South Africa we find a markup of about 30 per cent: three times as high as the 10 per cent markup found for the U.S.     

STAGFLATIONARY CONSEQUENCES OF PRUDENT MONETARY POLICY IN A UNIONIZED ECONOMY

Stylised models of the policy game between monetary policy makersand the private sector have suggested that discretionary policyregimes suffer from an inherent inflationary bias and that pre-commitmentto a target rate of inflation may be desirable. This paper showsthat in the presence of labour unions, the monetary policy gamecan lead to radically different results: a central bank thatis completely indifferent to the level of inflation may obtainoutcomes with high employment rates and zero inflation while‘prudent’, inflation-averse, central banks generatestagflation with positive inflation and low rates of employment.     

PRICE FLEXIBILITY IN THE COMMON MONETARY AREA

This paper examines the presence of flexibility within the common monetary area (CMA) as compared to a selected group of Southern African Development Co-operation (SADC) countries. The study tests for the readiness of SADC countries towards macroeconomic convergence and monetary unification. The methods followed examine the concept of (relative) purchasing power parity and test for the speed of adjustment of prices after a shock. The results suggest that the level of price flexibility is high within the CMA as opposed to the control group. The implication is that the CMA arrangement has managed to foster price flexibility among its member countries. Furthermore, Botswana could be a potential candidate for a monetary union with the CMA group.     

LIBERALISING TRADE IN SOUTH AFRICA: A SURVEY OF COMPUTABLE GENERAL EQUILIBRIUM STUDIES

This paper reviews applications of computable general equilibrium models to trade liberalisation in South Africa. It focuses on economic structure, data, macroeconomic closure and results of the models. The models project that trade liberalisation has had small positive impacts on growth. Poverty and inequality outcomes are less clear cut and depend on the model used. Models with fully integrated micro data find that poverty has worsened slightly while inequality has risen. Aggregated models predict that poverty has been reduced by small amounts. Dynamic models report rising inequality but falling poverty incidence. The paper identifies areas for future research.     

CAPITAL MOBILITY IN SUB-SAHARAN AFRICA: A PANEL DATA APPROACH

In this paper we are primarily concerned with assessing the degree of capital mobility in sub‐Saharan Africa. Using the methodology as proposed by Feldstein and Horioka (1980)—later termed the “Feldstein‐Horioka puzzle”—we test the hypothesis of perfect capital mobility against the alternative of imperfect capital mobility. Following Vamvakidis and Wacziarg (1998) and Isaksson (2000), provision is made in our model to show the dependency of the lesserdeveloped countries on international finance and aid and how a more open economy contributes towards improving the level of capital movement in these countries. We also assess the change in the degree of capital mobility over the time period in an effort to see whether institutional and political changes have been successful. We show that, compared to the region, South Africa is, to a large extent, more developed and should therefore play a leading role in the “African Renaissance”. Stationary panel data estimation techniques are applied to a sample of 36 sub‐Saharan African countries over the time period 1980–2000. The benefits of using one‐way error component models are derived from simultaneously employing time and cross‐section dimensions of the data, resulting in a substantial increase in the degrees of freedom. The fixed and random effects models enable us to acknowledge country heterogeneity within the panel, making provision for differences across countries like capital control policies, financial and capital market structures and exchange rate regimes.     

LONG-RUN M3 DEMAND IN SOUTH AFRICA: A COINTEGRATED VAR MODEL

This paper presents a system cointegration analysis of a long‐run demand for money (measured in terms of M3) in South Africa. In particular, the paper estimates a cointegrated vector autoregression model, consisting of real money, income and the opportunity cost of holding money. Using a variety of theory consistent identification schemes, the money demand function is identified along with other two cointegrating relations, namely, an IS‐type relationship and a relationship relating inflation to the spread between long‐ and short‐term interest rates. The model shows that of the variables used, only income and real money are error‐correcting to the money demand relation. The money demand relation is found to be relatively stable over the sample period, when short‐run fluctuations are corrected for. The model further shows that the long‐run link between money and inflation is rather weak.     

THE TRANSMISSION OF MONETARY POLICY UNDER THE REPO SYSTEM IN SOUTH AFRICA: AN EMPIRICAL ANALYSIS♣

The study examines the influence of the repo rate on the interbank rate and analyses whether the transmission channels of interest rates have changed since the adjustment to the repo system in September 2001. The paper employs the Granger causality test using the ECM framework. The results suggest that the influence of the repo rate on the interbank rate was stronger before the adjustments to the system were made. The interbank rate and the repo rate were found to “reverse” roles in the period after the adjustments to the system. Our results show that the changes to the repo system in 2001 did not lead to the achievement of the intended transmission channel; instead it was found that the system in place before the changes were made was in fact already achieving the transmission path that the authorities hoped to accomplish by changing the system.     

OPTIMAL PRE-COMMITMENT IN MACROECONOMIC POLICY: A GAME THEORETIC ANALYSIS OF FISCAL POLICY

The version of the paper published in Oxford Economic Papers(Volume 42, October 1990, pp. 695–714) erroneously omittedthe figures. This note presents the figures and briefly describesthe results they show. The paper proposed a new solution to the problem of time inconsistency.A subgame-perfect trigger strategy equilibrium was presentedin which the public expected the government to renege on itsoriginally announced policy at some later date. The government'spre-commitment to its announced policy was determined endogenouslyas part of the equilibrium. The equilibrium was illustrated using Blanchard's (1985) modelof fiscal policy. I examined the [political] problem of maintainingaggregate consumption while reducing the level of governmentdebt. The problem of time inconsistency arises in this contextbecause the government has an incentive to renege on its promiseto raise future taxes. Numerical solutions of the model showedthat the government would renege after a period that dependedon its expected tenure and preferences. Figures 1 to 4 showthe behavior of the economy under policies with no pre-commitment([t₀t^*) = 0), a moderate period of precommitment ([t₀t^*) = 33.5),and a long period of pre-commitment ([t₀t^*) = 140.2). Figure 1 shows that governments with greater credibility willprefer to push the costs of falling consumption further intothe future. This is achieved by adopting policies that promiseto raise future revenues while cutting current taxes so thatthe fall in the value of government debt is offset by the risein human wealth [see Figures 2 and 4]. One important consequenceof these policies is that the level of government debt risesduring much of the period of pre-commitment. Figure 5 is used in the appendix to prove proposition 1
