This paper determines which of the three policy approaches: fiscal, monetary and exchange rate can better address external imbalances in the three largest African economies, Nigeria, South Africa and Egypt. To this end, use is made of the panel vector autoregressive model to assess the dynamic effects of shocks emanating from the three policy approaches. The findings of the paper indicate that unlike in many emerging and developed economies the current accounts of these three economies react to fiscal, monetary and exchange rate shocks. More particular, the results of the empirical analysis show that the appreciations of the currencies in the three economies lead to current account surpluses. This is mainly attributed to the fact that most African economies have a high propensity to import with limited productive capacity for exports. 相似文献

This paper examines the evolution and the underlying forces of the business cycle co-movements among seven African (A-7) countries over the period 1970–2016. These countries accounted for over 60% of regional GDP, have abundant natural resources, access to the global capital market and widely viewed as potential drivers of regional (or “African”) business cycle. We model the national business cycle using real output, consumption and investment. We employ a dynamic factor model to decompose fluctuations in these macro-variables into a regional, country-specific and idiosyncratic components using Bayesian methods. We also analyse the relative importance of some notable drivers of business cycle fluctuations found in the literature. We find that the idiosyncratic component is dominating cyclical fluctuations in the A-7 countries, while country-specific and regional factors play a negligible role suggesting the inexistence of a common regional cycle despite deepening intra-African trade. Among the driving variables, the terms-of-trade shocks exert greater influence on the A-7 business cycle, while exchange rate movements and changes in money supply explain sizeable fluctuations in consumption and investment in most of the A-7 countries. Shocks associated with changes in relative domestic oil prices, monetary and fiscal policies cause large output fluctuations. 相似文献

This paper attempts to assess the extent of volatility spillovers between the equity market and the foreign exchange market in South Africa. Multistep family of the General Autoregressive Conditional Heteroskedasticity models are used for this end, whereby volatility shocks obtained from the mean equation estimation in each market are included in the conditional volatility of the other market, respectively. The paper selects the appropriate volatility models for each market following criteria such as covariance stationarity, persistence in variance and leverage effects. The finding of the paper indicates that there is a unidirectional relationship in terms of volatility spillovers from the equity market to the foreign exchange market. The paper supports the view that the extent of foreign participation in the South African equity market possibly contributes to this phenomenon. 相似文献

This paper assesses the extent of transmission of volatility shocks in the equity and foreign exchange markets among BRICS (Brazil, Russia, India, China and South Africa) countries to infer the degree of risk sharing and the possibility of a beneficial financial integration among its member countries. To this end, the paper makes use of the spillover index methodology suggested by Diebold and Yilmaz ( 2012 ). Nonetheless, the paper extends this methodology by incorporating ex ante volatility measures that account for long memory in equity and foreign exchange markets. The paper finds asymmetric influences among BRICS countries in relation to the cross transmission of risks. The finding of the paper implies the possibility of unequal benefit that could result from a possible capital market liberalization between the BRICS countries. 相似文献

This paper introduces the possibility of asymmetry in the reaction of output growth to inflation shocks in South Africa by making use of the Markov-switching vector autoregressive model. Using quarterly data from 1969Q1 to 2013Q4, the empirical finding suggests that the reaction of output growth to inflation shocks is not only regime dependent but is also contingent on how the monetary authority reacts to such shocks. Two important regimes are identified; the high and low inflation volatility regimes. Consistent with the signal extraction theory, the output effect of inflation shocks is found to be significantly lower in the high inflation volatility regime compared to the low inflation regime. 相似文献

This article provides an assessment of the comparative effectiveness of four econometric methods in estimating the optimal hedge ratio in an emerging equity market, particularly the South African equity and futures markets. The article bases the effectiveness of hedging on volatility reduction and minimization of the coefficient of variation of hedged returns as well as risk-aversion-based utility maximization. The empirical analysis shows that the vector error-correction method and multivariate generalized autoregressive conditional heteroscedasticity methods are most effective over relatively long horizon, weekly and monthly hedging periods. 相似文献

This paper assesses the relationship between trade openness and economic growth in Africa by accounting for the heterogeneity of African countries. In addition, the paper contributes to the literature on trade openness and economic growth nexus by applying the instrumental variable panel smooth transition regression, a methodology that accounts for nonlinearity and endogeneity in the relationship between the two variables. The results of the empirical analysis reveal that the investment ratio is a channel through which trade openness affects economic growth in the African continent. In addition, the relationship between trade openness and economic growth varies according to the degree of a country's development in Africa. The study finds a negative relationship between openness and growth in low-income countries. Conversely, for upper-income countries, the coefficients of trade indicators are positive and statistically significant. The results indicate that African countries are not homogeneous, especially concerning trade openness and economic growth nexus. 相似文献
