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.     

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.     

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.     

INTEREST RATE PASS-THROUGH IN THE COMMON MONETARY AREA OF THE SACU COUNTRIES

We investigate the interest rate pass‐through in the four Common Monetary Area (CMA) countries of the South African Customs Union (SACU). We employ an empirical pass‐through model that allows for thresholds, asymmetric adjustment, and structural changes. We show that CMA bank lending markets exhibit quite some degree of homogenization as the pass‐through is often fast and complete. Deposit markets are somewhat more heterogeneous by showing differing degrees of interest rate stickiness and asymmetric adjustment. Policy makers should therefore be concerned about imperfect competition which may be at the heart of the remaining cross‐country differences in monetary transmission in the CMA.     

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.     

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.     

EXCHANGE MARKET PRESSURE,MONETARY POLICY,AND ECONOMIC GROWTH: ARGENTINA, 1993–2004

The exchange market pressure (EMP) against a currency has been frequently measured as the sum of the loss of international reserves plus the loss of nominal value of that currency. This paper follows the tradition of investigating the interactions between such a measure of EMP and monetary policy; but it also questions the usual omission of output growth in empirical investigations. The focus of this work is Argentina between 1993 and 2004. As in previous studies, we found some evidence of a positive and double‐direction relationship between EMP and domestic credit. But output growth also played a role in the determination of EMP, even more than domestic credit or interest rates. Also, there is some evidence that EMP affected growth negatively.     

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.     

THE ROLE OF COMMODITY PRICES IN MACROECONOMIC POLICY IN SOUTH AFRICA

This paper examines whether commodity prices can be used as signal for informing macroeconomic policy in South Africa using the new approach for testing Granger causality developed by Toda and Yamamoto (1995 ). Evidence of causality from average gold price to interest rate, money, exchange rate and the consumer price index was observed. Again, evidence of causality was observed from metals price index to interest rate, money and exchange rate. The results suggest there is merit in using South Africa's average gold price and the metals price index of the International Monetary Fund as informational variables in setting monetary policy.     

CAN A RULE‐BASED MONETARY POLICY FRAMEWORK WORK IN A DEVELOPING COUNTRY? THE CASE OF YEMEN

Monetary policy in Yemen is largely rudimentary and ad hoc in nature. The Central Bank of Yemen's (CBY) approach has been based on discretionary targeting of broad money without any clear target to anchor inflation expectations. This paper argues in favor of a new formal monetary policy framework for Yemen emphasizing a proactive and rule‐based approach with a greater direct focus on price stability in the context of a flexible management of the exchange rate. Although, as in many developing countries, institutional capacity is a concern, adopting a more formal framework could impel the kind of changes that are required to strengthen the ability of the CBY in achieving low and stable rates of inflation over the medium term.     

MONETARY POLICY IN RWANDA: A COINTEGRATION ANALYSIS

Countries in Africa are increasingly becoming similar in outlook, especially as regards monetary policy. With a view to conducting a long‐term study of monetary policy in Africa, we apply an empirical test for the coherence of inflation targeting, first conducted by Nell (2003 ) for South Africa, to data from Rwanda. We find that like South Africa, Rwanda has a stable money demand function and the adoption of an inflation target is a wise policy option. Also, the Rwandan money market needs just over five quarters to eliminate half of any monetary disequilibrium. These results are of some interest to economists and policy makers for all the countries in the increasingly interconnected continent of Africa.     

Inflation and Inflation Expectations in South Africa: an Attempt at Explanation

This paper examines the relationship between inflation and inflation expectations in South Africa. We use inflation expectations derived from the quarterly surveys conducted by the Bureau of Economic Research from 2001Q1 to 2011Q4 . Using these data, we estimate the model assuming that private sector expectations are a linear function of the inflation target and lagged inflation. The results indicate that economic agents' expectations largely depend on lagged inflation. This suggests that the South African Reserve Bank (SARB) has not been successful in anchoring expectations of the private sector since the adoption of the inflation targeting (IT) regime in 2000. We also find evidence indicating that the SARB's implicit inflation target lies above the upper bound of the official IT band. Finally, it appears that the SARB has been more concerned about output stabilisation than inflation stabilisation.     

THE CHANGING VOLATILITY OF THE SOUTH AFRICAN ECONOMY

During the last decade economic literature explored the presence of and reasons for what became known as “the great moderation” in the US and other G7 countries. “The great moderation” describes the decrease in economic volatility experienced in many of the G7 countries. This paper finds that in South Africa volatility is also not constant (it even finds that there are autoregressive conditional heteroskedastic effects present) and that volatility also decreased, particularly since 1994. Following the literature, the paper explores several reasons for this decrease and finds that smaller shocks, better monetary policy and improvements in the financial sector that place less liquidity constraints on individuals and allow them to manage their debt better are some of the main reasons for the reduction in the volatility of the South African economy. The literature on the G7 also suggests that better inventory management contributed to the lower volatility. However, this seems not to be true for South Africa.     

CAN TUNISIA MOVE TO INFLATION TARGETING?

Inflation targeting has become an alternative monetary strategy that has been followed by many industrial and emerging countries. This study considers whether the adoption of inflation targeting would be relevant for Tunisia. More specifically, this paper aims at checking whether the necessary conditions for the successful implementation of such a strategy are fulfilled or not. It is found that fiscal dominance does not constitute the main hindrance to the adoption of inflation targeting. Other impediments have been identified, especially a weak financial system in general, the unsound and fragile banking system in particular, and the glaring lack of knowledge about the monetary transmission mechanism. Furthermore, it has been pointed out that if Tunisian monetary authorities continue to carry out the present exchange rate regime, namely, the constant real exchange rate rule, an inflation targeting regime will not be sufficient to properly contain the inflation pressures caused by demand shocks.     

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.     

Multiple Structural Breaks and Inflation Persistence: Evidence from China

The degree of inflation persistence fluctuates more in developing countries than in industrialized countries. This is because there are more economic reforms in developing countries than in industrialized countries. Hence, it is important to study the inflation persistence in developing countries. The present paper investigates the pattern of inflation persistence in China, a developing and transitional economy. Specifically, the paper studies statistically the number of structural breaks in China's inflation persistence based on the monthly retail price index (MRPI) and the quarterly retail price index (QRPI) inflation series from 1983 to 2011. The findings show that there are five and three structural breaks in the MRPI and QRPI inflation persistence, respectively. The present paper also exposes a high degree of persistence over the whole sample period and a slight decline in the level of the persistence since 1994. Furthermore, the persistence of two inflation series does not change monotonously but with obvious cyclical patterns. Using these derived estimated structural breakpoints, likely causes of the breakpoints in inflation persistence are investigated. Finally, theoretical and practical implications are discussed.     

THE SENSITIVITY OF SOUTH AFRICAN INFLATION EXPECTATIONS TO SURPRISES

Price stability is widely recognised as the primary goal of modern monetary policy, and the management of private sector inflation expectations has become an essential channel through which this goal is achieved. This evaluation aims to improve the understanding of how the sensitivity of private sector inflation expectations to macroeconomic surprises in South Africa compares internationally, as this provides an indication of the contribution of monetary policy in South Africa to anchoring inflation expectations. If a central bank is credible, the financial markets should react less sensitively to macroeconomics surprises, because they trust the central bank to manage these incidents and achieve the objectives they communicated over the medium to long term. In this paper, the methodology of Gurkaynack et al. is adopted in order to measure the sensitivity of South African inflation expectations to surprises. A comparison of South Africa's results with those of countries in the original studies supports the contention that the SARB (South African Reserve Bank) has encouraged inflation expectations to be relatively insensitive to macroeconomic surprises, and offers support for the inflation-targeting framework as a means to help anchor inflation expectations.     

MEASURING INFLATION CREDIBILITY: RESULTS OF A FIRST REPRESENTATIVE SOUTH AFRICAN SAMPLE

This study reports the measurement of inflation credibility of a representative sample of the South African population in terms of an inflation credibility barometer. The barometer is an instrument measuring the degree of acceptance of the accuracy of historic inflation figures. These research results serve as a benchmark for South Africa, as similar measurement of a representative sample has not been undertaken before. The sampling results show little public understanding of the rate of inflation and its measurement of average price increases experienced by an average household. As generally accepted international benchmarks for successful central-bank communication strategies do not exist, the application of the methodology reported in this paper can improve the effectiveness of central bank communication aimed at improving the general knowledge about inflation.     

INFLATION TARGETING AND THE FISHER EFFECT IN SOUTH AFRICA: AN EMPIRICAL INVESTIGATION

The paper analyses the relationship between expected inflation and nominal interest rates during a period of inflation targeting in South Africa, i.e. from 2000 to 2005. Specifically, it investigates the Fisher hypothesis that nominal interest rates move one‐to‐one with expected inflation, leaving the real interest rate unaffected. The analysis distinguishes between a short‐run Fisher effect and a long‐run Fisher effect. Using cointegration and error correction models (for monthly data for the period April 2000 to July 2005), it was found that the short‐run Fisher hypothesis did not hold during the relevant period under the inflation targeting monetary policy framework in South Africa. This is attributed to a combination of the South African Reserve Bank's (SARB) control over short‐term interest rates and the effects of the monetary transmission mechanism. The long‐run Fisher hypothesis could not be confirmed in its strictest form: while changes in inflation expectations move in the same direction as the nominal long‐term interest rate. This suggests that monetary policy has an influence on the real long‐term interest rate, which has positive implications for general economic activity, thus confirming the credibility of the inflation targeting framework.
