Modelling Monetary Union in Southern Africa: Welfare Evaluation for the CMA and SADC

This paper proposes a quantitative assessment of the welfare effects arising from the Common Monetary Area (CMA) and an array of broader groupings among Southern African Development Community (SADC) countries. Model simulations suggest that (i) participating in the CMA benefits all members; (ii) joining the CMA individually is beneficial for all SADC members except Angola, Mauritius and Tanzania; (iii) creating a symmetric CMA‐wide monetary union with a regional central bank carries some costs in terms of foregone anti‐inflationary credibility; and (iv) SADC‐wide symmetric monetary union continues to be beneficial for all except Mauritius, although the gains for existing CMA members are likely to be limited.     

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.     

Measuring Multi‐Membership in Economic Integration and Its Trade Impact: A Comparative Study of ECOWAS and SADC

One of the intriguing aspects of African regional trade agreements (RTAs) is the extent of multi‐membership, where many African countries are members of more than one RTA. Using a gravity model for 25 countries and the years 1980‐2006, we measure the extent of multi‐membership and compare its impact in two major African regional blocs, Economic Community of West Africa States (ECOWAS) and Southern Africa Development Community (SADC). We find that the impact of multi‐membership critically depends on the characteristics of the multi‐membership of regional integration initiatives. We find a positive impact if an additional membership complements the integration process of the original regional integration initiative: overlapping memberships had a much stronger and significant positive effect on bilateral trade within ECOWAS compare with an insignificant impact within the SADC.     

AN ANALYSIS OF MACRO‐ECONOMIC CONVERGENCE IN SADC1

One of the goals of the Southern African Development Community (SADC) is macro‐economic convergence leading to monetary unification and a single central bank. This goal is aligned with the goal of the African Union to build a monetary union for the entire continent in stages, starting with each of the subregions, of which SADC forms one important region. Despite views to the contrary, the current degree of compliance with the Maastricht criteria for convergence and membership of the European Union, shows that the challenges facing a SADC monetary union would not be insurmountable if the convergence criteria are viewed as permanent goals, rather than preconditions.     

Monetary autonomy in selected Asian economies: The role of international reserves

With the increased financial integration of Asian countries, monetary policy takes on the additional role of maintaining the stability of the financial system along with the traditional objectives of promoting growth and employment with price stability. Given the importance and relevance of monetary policy in Asian countries, we examine monetary autonomy and its interaction with financial integration, currency regimes and international reserves for the past two decades in the following Asian countries: Thailand, Korea, Indonesia, the Philippines, and India. The empirical analysis reveals two significant and interesting findings that have policy implications. First, Thailand, Korea and Indonesia, countries that have moved towards a floating currency regime, experienced simultaneous declines in the sensitivity of their interest rates (thereby increasing monetary autonomy), while India continues to increase the sensitivity of its interest rates with a pegged exchange rate and increased financial integration. Second, in all of the studied economies, the accumulation of international reserves has contributed, to some extent, to the retention of monetary autonomy in terms of preventing the sensitivity of the interest rates from rising. We speculate that the accumulation of reserves plays the role of an anchor for monetary autonomy in emerging market economies facing a “fear of floating”.     

Credibility of European economic convergence

Credibility of European Economic Convergence. — The authors analyze economic convergence and its relation to European real interest rate differentials using a clustering method on seven macroeconomic key variables for 1979–1995. The results indicate that monetary convergence has progressed considerably but that there is hardly any real convergence in the EU. They also perform pooled nominal and real interest rate regressions with the individual cluster indicators as explanatory variables. The authors find significant positive effects of external (current account) and internal (unemployment ratios, government finance) imbalances on real interest rates. They also group countries according to economic reputation and find that real indicators remain significant for the high-reputation countries.     

Is There a Bank Lending Channel in Southern African Banking Systems?

Abstract: Macroeconomic models currently used by policymakers generally assume that the functioning of financial markets can be fully summarized by financial prices, because the Modigliani and Miller (1958) theorem holds. However, the assumption that this theorem holds is questionable. This paper argues that there are frictions in the market which traditional models based on the Modigliani and Miller theorem fail to take into account in explaining how monetary policy and other shocks are transmitted to the economy and points to new directions. A comprehensive macroeconomic model should incorporate financial market interactions to enhance the understanding of the transmission mechanisms of monetary policy and other shocks. If market dynamics are not taken into account, macroeconomic models used by policymakers may point to wrong policy choices. Motivated by the lack of assessment of the recently launched financial reforms, deregulation, consolidations, financial innovations and joint payment systems, the paper assesses the process of monetary transmission mechanism by investigating evidence of a bank lending channel in SADC during the period 1990–2006 using data from the banking sector. Data from a panel of banks is used to identify shifts in the loan supply curve in response to changes in monetary policy using a vector autoregression (VAR) model. Although the results are mixed the paper generally reports the existence of a bank‐lending channel in all SADC countries in the sample. The take‐off point for monetary policy effects differs from one country to another.     

Free Trade Agreements and the SADC Economies

Countries in southern Africa have engaged in a variety of tradeliberalisation initiatives such as the European Union (EU)–SouthAfrica Free Trade Agreement (FTA), the EU's ‘Everythingbut Arms’ (EBA) initiative to eliminate trade barriersagainst imports from the least developed countries and a potentialFTA among Southern African Development Community (SADC) countries.In this paper we use a multi-country computable general equilibrium(CGE) model to analyse the impact of trade liberalisation inthe region. First, we analyse the FTA between South Africa andthe EU. Then, we consider how the rest of southern Africa mightrespond: (i) by enforcing an SADC FTA; (ii) by exploiting theadvantages of unilateral access to the EU in addition to anSADC FTA; and (iii) by entering an FTA with the EU and otherSADC countries. The scenarios are ordered such that the SADCcountries pursue increased trade liberalisation. We find thatunder all FTA arrangements the increased total imports fromFTA partners exceeds the reduction in imports from non-FTA partners— the FTAs examined are all net trade creating. Some SADCeconomies are slightly hurt by the FTA between the EU and SouthAfrica, while others gain slightly. Overall, the agreement isnot a beggar-thy-neighbour policy. We also find that unilateralaccess to the EU is more beneficial for SADC countries thanan SADC FTA because the SADC countries trade more with the EUthan with each other. However, reciprocal reforms under an EU–SADCFTA dominate unilateral access to the EU because they requiremore structural adjustment in the SADC countries. Finally, wefind that South Africa is not large enough to serve as a growthpole for the region. Access to EU markets provides substantiallybigger gains for the other SADC countries than access to SouthAfrica.     

SADC Trade with the European Union from a Preferential to a Reciprocal Modality

This study employs a global computable general equilibrium (CGE) model to examine the potential impacts of the Economic Partnership Agreements (EPAs) between the European Union (EU) and the Southern African Development Community (SADC). The simulation results suggest that a comprehensive EPA scenario is welfare‐improving for many SADC members. SADC preferential access to the EU markets is the key source for the prospective welfare and terms of trade gains. Overall, SADC production structures become more concentrated in export‐oriented sectors. These structural changes are accompanied by a high degree of adjustment and substantial fiscal losses.     

Trans-Tasman Transmission of Monetary Shocks: Evidence From a VAR Approach

This paper investigates the cross-country transmission mechanisms of monetary shocks between Australia and New Zealand within a VAR framework for the period 1985:1–2003:4. The empirical results indicate that a monetary shock in either Australia or New Zealand has real effects in the short-run in both countries however, an Australian shock generates more significant responses of most variables. Australian output is found to be significantly more sensitive than New Zealand output to monetary innovations in either country. The results also suggest that monetary innovations in a small open economy can also influence its larger trading partner.The authors would like to thank Faik Koray and an anonymous referee for their valuable comments.

Is there a link between BRIC foreign direct investment and SADC export performance?

The BRICS (Brazil, Russia, India, China and South Africa) countries have agreed to strengthen their economic ties, thus paving the way for enhanced trade and investment performance. South Africa's strategic value in BRICS is that it is a gateway to the opportunity-rich Southern African Development Community (SADC). By using South Africa as a production hub for exports to the surrounding region, foreign investors would have ready access to neighbouring markets. This article addresses the question of whether, and in what ways, foreign direct investment (FDI) from the BRIC (Brazil, Russia, India and China) countries to the SADC influences the SADC's export performance. A series of empirical analyses revealed a positive causation between BRIC FDI and SADC exports, offering a clear incentive for the SADC to rejuvenate its trade and investment policies and structures, and strengthen its ties with BRIC countries in the interests of attracting more FDI and building a strong and sustainable export sector.     

The monetary exchange rate model in the long run: An empirical investigation

The Monetary Exchange Rate Model in the Long Run: An Empirical Investigation. — This paper uses the Johansen multivariate cointegration method to examine three variants of the monetary approach to the long-run exchange rate model: flexible price, forward-looking and sticky price monetary models. Evidence is provided for four bilateral sterling exchange rates. The sensitivity of the results to the measurement of monetary aggregates is also examined. The cointegration results provide dismal evidence for the flexible price and forward-looking models irrespective of the measurement of money. The findings are more mixed for the sticky price model, particularly when broad money is used.     

On the choice of an anchor for the GCC currency: does the symmetry of shocks extend to both the oil and the non-oil sectors?

This paper assesses the costs of forming a monetary union among the Gulf Cooperation Council (GCC) countries by looking at economic linkages within the GCC, and between the GCC and the potential anchors (the US, and major European countries such as France, Germany and Italy) for their proposed new currency. We investigate the importance of the US dollar compared to the Euro by focusing on aggregate demand (AD) and aggregate supply (AS) shock symmetry across these countries. We differentiated between oil and non-oil sector by estimating structural vector autoregression (SVAR) models with a combination of variables: oil output, non-oil output, total output, nominal/real price of oil and overall price level. One set of models was identified with the long-run restrictions of Blanchard and Quah (Am Econ Rev 79(4):655–673, 1989), whereas the set that assesses the robustness of the findings was estimated with the short-run restrictions of Sims (Eur Econ Rev 36(5):975–1000, 1992). We find overwhelming support for AD shock symmetry across the GCC countries and between the GCC and the US, but none for the major European countries with the GCC. Non-oil AS shocks are mostly asymmetric, but oil AS shocks are mostly symmetric when the real price of oil is included. This agrees with the view that GCC countries are subjected to common oil shocks. It also suggests that previous VAR models estimated to pass judgment on the feasibility of monetary union across GCC countries may have suffered from problems of mis-specification if the real price of oil was not considered. We surmise that the US dollar is a better anchor candidate for anchoring the new GCC currency than the Euro, since US monetary policy can at least help smooth demand shocks in these countries.     

FINANCIAL AND MONETARY AUTONOMY AND INTERDEPENDENCE BETWEEN SOUTH AFRICA AND THE OTHER SACU COUNTRIES

The paper uses cointegration and error correction modelling techniques together with tests of weak exogeneity, and monthly interest rates for the period 1990 to 2005, to examine the degree of financial and monetary autonomy and interdependence between South Africa and the other Southern African Customs, Union (SACU) countries. The results reveal a high level of dependence of the other SACU countries' financial systems on South Africa's financial system, which suggests that a monetary unification with a single central bank (South African Reserve Bank) and monetary policy for the union is feasible.     

A comparative analysis of monetary responses to global oil price changes: net oil producing vs. net oil consuming countries

In this paper, we examine monetary responses to global oil price changes across a panel of seven major net oil consuming countries and three major net oil producing countries using monthly data from January 1986 to August 2013. Employing a variety of linear and nonlinear causality tests, our main findings are as follows. First, oil price movements directly affect monetary aggregates in both net oil consuming and net oil producing countries. Second, nonlinear causality tests reveal strong causal influences from oil prices to monetary aggregates. Third, nonlinear parametric and nonparametric models reveal oil price changes account for significant changes in monetary aggregates in Denmark, Germany, the Netherlands, and the US among net oil consuming countries and in Canada and Mexico among net oil producing countries. Finally, monetary aggregates in these countries respond nonlinearly only to oil price increases.     

The Relationship Between Price Stability and Financial Stability: Evidence From Major Emerging Economies

We examine the relationship between price stability and financial stability for major emerging economies using a Markov regime-switching model. Empirical results suggest that monetary policy is consistent with the Taylor rule in all countries except for India and all countries followed both low and high inflation targeting monetary policy regimes. Low inflation targeting regime seems to be more persistent and has higher duration than high inflation targeting regimes except for Indonesia and South Africa. All countries seem to have had financial stability concerns when they formulated their monetary policy as the coefficient of the financial stress index is statistically significant at least in one regime. Overall the results suggest that Taylor rule-based monetary policies have been implemented to various degrees in major emerging economies to achieve economic stability, price stability, and financial stability.     

IS EAST ASIA FIT FOR AN OPTIMUM CURRENCY AREA? AN ASSESSMENT OF THE ECONOMIC FEASIBILITY OF A HIGHER DEGREE OF MONETARY COOPERATION IN EAST ASIA

This paper attempts to make a contribution to the recent search for a suitable assessment of the economic feasibility of a higher degree of monetary cooperation in East Asia. By using a structural vector autoregression approach as well as a generalized purchasing power parity approach, we find that a larger group of appropriately selected East Asian economies does satisfy the macroeconomic conditions for forming an Optimum Currency Area (OCA). The East Asian group consists of four ASEAN countries (Indonesia, Malaysia, Singapore, and Thailand) and four Northeast Asian economies (Hong Kong SAR, Japan, Republic of Korea, and Taiwan). This finding presents a striking contrast to the existing research results whose policy recommendation has generally been that countries in East Asia should start with a smaller subgroup currency area. It is time that many East Asian economies as a region made a serious effort to pursue a higher degree of monetary cooperation among themselves for forming an OCA.     

The value of gold as a reserve asset

An unresolved feature of the present international monetary system is the absence of any agreement, formal or informal, as to the appropriate price at which gold held as a reserve asset is to be valued. This omission has become increasingly evident in recent months as the market price of gold has surged to levels 10 times as high as the former official price. While the majority of countries continue to value gold at the former official price, an increasing number have adopted valuations based on the market price. The existing ambigous situation with respect to gold valuation is not a viable one and, if present trends continue, the likely result will be a de facto revaluation of gold reserves at the market price. The quantitative implications of this are enormous, for the effective level of world reserves doubles when gold is valued at the current market price. Such a revaluation of gold would have a large impact on the future evolution of the international monetary system and, in particular, would cast a considerable degree of doubt on the possibility of attaining the internationally agreed goal of making special drawing rights (SDR) the principal reserve asset. In addition, the distribution of the increased international liquidity which has resulted from the rise in the market price of gold has been highly uneven, since world gold reserves are concentrated in a very small number of countries. A number of other countries, notably the non-oil-exporting developing countries, have strong grounds for objecting to the fact that this large increase in international liquidity has occurred as a result of an effective revaluation of gold rather than via increased allocations of SDR.     

Labour Market Asymmetries in a Monetary Union

This paper takes a first step in analysing how a monetary union performs in the presence of labour market asymmetries. Differences in wage flexibility, market power and country sizes are allowed for in a setting with both country-specific and aggregate shocks. The implications of asymmetries for both the overall performance of the monetary union and the country-specific situation are analysed. It is shown that asymmetries are not only critical for country-specific performance but also for the overall performance of the monetary union. A striking finding is that aggregate output volatility is not strictly increasing in nominal rigidities but hump-shaped. Moreover, a disproportionate share of the consequences of wage inflexibility may fall on small countries. In the case of country-specific shocks, a country unambiguously benefits in terms of macroeconomic stability by becoming more flexible, while this is not necessarily the case for aggregate shocks. There may thus be a tension between the degree of flexibility considered optimal at the country level and at the aggregate level within the monetary union.     

TESTING FOR FRACTIONAL INTEGRATION IN SOUTHERN AFRICAN DEVELOPMENT COMMUNITY REAL EXCHANGE RATES

This paper utilises “a class test for fractional integration” associated with the seminal contribution of Hinich and Chong to appraise the possibility that Southern African Development Community (SADC) real exchange rates can be treated as long memory processes. The justification for considering fractional integration is that the general failure to reject the unit‐root hypothesis in real exchange rates is caused by the restrictiveness of standard unit‐root tests regarding admissible low‐frequency dynamic behaviour. The paper presents evidence that, except for South Africa, none of the SADC real exchange rates are fractionally integrated. However, the results are found to be sensitive to the size of the sample.
