Equity,Bonds, Institutional Debt and Economic Growth: Evidence from South Africa

We examine the finance‐growth nexus in South Africa accounting for the role of bond markets, stock markets, and bank and non‐bank financial intermediaries using a vector autoregressive technique. Extant empirical literature has largely accounted for only banks and stock markets, ignoring bond market and non‐bank financial intermediaries. We find that bond market development affects economic growth in South Africa, and no similar effect is observed for the bank and non‐bank financial intermediaries and the stock market. Our finding shows that examination of individual elements of the financial system is important in understanding the unique effect of each on growth. The observation that the bond market rather than stock market, bank and non‐bank institutions promote economic growth in South Africa induces an intriguing question as to what unique roles bond markets play that the intermediaries and equity market are unable to play.     

The Impact of Firm Size and Liquidity on the Cost of External Finance in Africa

Established illiquidity measures are constructed for emerging markets in Africa and used to determine which best explains trading costs. Costs of equity are derived from an augmented Capital Asset Pricing Model for a sample of emerging financial markets generally ignored in the literature. These include: South Africa and Namibia, three countries in North Africa and four in Sub‐Saharan Africa (SSA), plus London and Paris as examples of integrated markets. Minimum variance portfolios are constructed and asset weights derived, with the sample divided into countries dependent on their legal regime. Portfolio weights are shown to be directly related to well‐regulated markets with high standards of corporate governance and disclosure, and firms seeking cost‐effective finance from SSA stock markets are at a distinct disadvantage compared with those in Northern Africa, South Africa and, in particular, London and Paris.     

RISK–RETURN TRADE‐OFF AND BEHAVIOUR OF VOLATILITY ON THE SOUTH AFRICAN STOCK MARKET: EVIDENCE FROM BOTH AGGREGATE AND DISAGGREGATE DATA

The study analyses the nature and behaviour of volatility, the risk–return relationship and the long‐term trend of volatility on the South African equity markets using aggregate level, industrial level and sectoral level daily data for the period 1995‐2009. By employing dummy variables for the Asian and the sub‐prime financial crises and the 11 September political shock, the study further examines whether the long‐term trend of volatility structurally breaks during financial crises and major political shocks. Three time‐varying generalised autoregressive conditional heteroskedasticity models were employed: one of them symmetric, and the other two asymmetric. Each of these models was estimated based on three error distributional assumptions. The findings of the study are as follows: First, volatility is largely persistent and asymmetric. Second, risk at both aggregate and disaggregate level is generally not a priced factor on the South Africa (SA) stock market. Third, the threshold autoregressive conditional heteroscedasticity (TARCH) model under the generalised error distribution is the most appropriate model for conditional volatility of the SA stock market. Fourth, volatility generally increases over time, and its trend structurally breaks during financial crises and major global shocks. The policy and investment implications of the findings are outlined.     

LONG MEMORY IN SOUTHERN AFRICAN STOCK MARKETS

The paper examines long memory in equity returns and volatility for stock markets in Botswana, South Africa and Zimbabwe using the ARFIMA‐FIGARCH model in order to assess the efficiency of these markets in processing information. The findings are diverse. Significant long memory is demonstrated in the equity returns of Botswana; while, in South Africa this result is not statistically different from zero. For Zimbabwe returns are characterised by an anti‐persistent process. Furthermore, all the markets investigated provide evidence of long memory in volatility with the exception of Botswana where there is no evidence of volatility persistence and hence the return from taking risk in this market cannot be predicted on the basis of previous values.     

LIQUIDITY AND THE INFORMATIONAL EFFICIENCY OF AFRICAN STOCK MARKETS

The hypothesis that a stock market price index follows a random walk is tested for 11 African stock markets, Botswana, Côte d'Ivoire, Egypt, Ghana, Kenya, Mauritius, Morocco, Nigeria, South Africa, Tunisia and Zimbabwe using joint variance ratio tests with finite-sample critical values, over the period beginning in January 2000 and ending in September 2006. The iid random walk hypothesis is rejected in all 11 markets. In four stock markets, Egypt, Nigeria, Tunisia and South Africa, weekly returns are a martingale difference sequence. Liquidity is an important factor which contributes to whether a stock market follows a random walk.     

Interaction between Foreign and Domestic Investors in the Korean Stock and Futures Markets*

The present paper analyzes the behavioral relations of major investor groups in the stabilized Korean stock and futures markets after the 1997 Asian financial crisis. Investor groups cannot be classified as positive or negative feedback traders on market returns when both stock and futures markets are considered, which is inconsistent with the results in Ghysels and Seon (2005). Foreign investors and domestic institutions tend to take opposite positions in both markets. The impact of foreign investors on the basis change is significantly negative in the futures market, whereas domestic institutions have a negative relation in the stock market. This supports the view that selling activity of foreign investors in the futures market pulls the futures price down compared with the index value and, consequently, induces the reverse cash‐and‐carry trade of domestic institutions. This relationship, which negatively influenced the Korean economy during the crisis, as shown in Ghysels and Seon (2005), still exists in the Korean financial markets.     

OPPORTUNITIES AND COSTS OF PORTFOLIO DIVERSIFICATION IN SADC'S SMALLEST EQUITY MARKETS

This paper contrasts the performance of three time series models, a simple stochastic drift, GARCH, and a time varying parameter CAPM for three of SADC's smallest equity markets: Namibia, Swaziland and Mozambique. Analysis of the portfolio characteristics for each reveals the level of integration with South Africa using optimised portfolio frontiers. In addition, the implications of adopting a minimum investment retention levy by the smaller states is examined. Namibia is found to exhibit the greatest degree of integration with South Africa, followed to a much lesser extent by Swaziland with Mozambique. The evidence suggests that investors in the smaller markets would face considerable additional costs should such a policy be adopted.     

LIQUIDITY AND VALUATION IN EAST AFRICAN SECURITIES MARKETS

This study estimates liquidity premiums using the recently developed Liu measure within a multifactor capital asset pricing model including size premiums and a time‐varying parameter model for the East African emerging markets of Uganda, Tanzania and Kenya together with London and South Africa. The evidence suggests that while size and liquidity effects are significant in the smaller emerging markets of Uganda and Kenya, they are less important in explaining returns in South Africa and London. Costs of equity are highest in Uganda followed by Kenya, with industrial and consumer non‐cyclical sectors being lowest, and then South Africa and London.     

Renewable energy and local development: Seven lessons from the mining industry

Having long depended on fossil fuels for energy generation, South Africa is now investing in renewable energy. Like its mining operations, its renewable energy plants will have local implications. Renewable energy companies are therefore required by government to engage with communities to contribute to socio-economic development. We present seven lessons we believe the renewable energy sector can learn from the mining industry. We argue that the new industry must: manage social disruption, understand community complexities, create responsive institutions and the capacity to support industry practice, employ trained community practitioners, be clear about the aims of local development, encourage economic diversification in remote areas and, importantly, in view of problems caused by downscaling in the mining industry, plan for the possible closure of projects. Renewable energy projects could then serve and shape local development.     

REGIONAL INTEGRATION OF EQUITY MARKETS IN SUB-SAHARAN AFRICA

Equity markets in developing and emerging economies have grown in number and importance as a result of financial market globalisation. However, their role in economic growth and development is enhanced if nascent markets are integrated with well‐established ones. Market integration, measured by the transmission of returns volatility, is identified across a sample of SSA countries, using a unique dataset. Evidence for potential integration between financial markets in Sub‐Saharan Africa (SSA) is found. Spillovers are found across markets, some unidirectional and others bi‐directional. However, continued illiquidity and incomplete institutions indicate that an integrated financial community remains premature, and considerable regulatory reform and harmonisation will be necessary for this to succeed.     

The Effects of Financial Statement Information Proximity and Feedback on Cash Flow Forecasts*

The Financial Accounting Standards Board (FASB) and International Accounting Standards Board (IASB), in their joint Financial Statement Presentation project, are reconsidering the basic format of financial statements. The Boards’ preliminary discussions related to this joint project indicate that they intend to modify the required financial statements to increase the proximity of performance‐related information for each reported period. We provide evidence related to this potential change by investigating the effects of financial statement information proximity on investors’ ability to learn the forecast‐relevant time series properties of reported cash flows and accruals. We also examine the role feedback plays in this relationship. Our experimental results suggest that nonprofessional investors are able to more quickly learn the relation between current period cash flows and accruals and future cash flow realizations when financial statement information is presented in a single statement rather than separated into two statements. In addition, we find that nonprofessional investors exhibit lower levels of absolute forecast errors and less forecast dispersion when financial statement information is unified into a single statement. Finally, we provide evidence that nonprofessional investors who receive extensive outcome feedback on a single page initially learn more quickly and later, after learning has leveled off, accurately forecast more consistently than do investors who receive extensive or limited feedback spread across two pages. Overall, our results provide evidence on the effectiveness of alternate financial statement presentation formats and the potential usefulness of receiving more extensive feedback.     

Major International Information Flows Across the Safex Wheat Market

We study information flows across four wheat futures markets on four continents: Zhengzhou Commodity Exchange (ZCE), South African Futures Exchange (SAFEX), Euronext/Liffe and Kansas City Board of Trade (KCBT). Three approaches for studying information flows among non‐synchronous markets are applied: cointegration techniques, vector autoregressive analysis and multiple regression proposed. Although comparable underlying assets are traded in the four markets, our results indicate that no long‐run links exist among them. ZCE is by far the most endogenous market, and Euronext/Liffe is the most exogenous one. Finally, the model points to KCBT as the most influential and sensitive wheat market. Our findings indicate that the relative openness of the SAFEX wheat market supports information flows and linkages from KCBT and Euronext/Liffe. Therefore, our results suggest that more supportive policies to incentivise higher wheat production in South Africa are required to mitigate the impact of price shocks emanating from the global wheat markets.     

Who Plays the Key Role among Shanghai, Shenzhen and Hong Kong Stock Markets？

In this paper we examine the daily frequency stock market indices of Shanghai, Shenzhen and Hong Kong from January 2000 to June 2012, and use the Morlet wavelet coherence model to determine who is playing the most important role in the financial markets of China. We find that there are significant comovements between these stock markets in the medium and long run. This provides investors with opportunities to increase their capital gains. The Hong Kong stock market plays a leading role in the long run, but its leader position is threatened by fast‐growing Chinese mainland stock markets, especially the Shanghai Stock Exchange. Based on our analysis, the following suggestions apply to the Chinese stock markets: establish and improve international and regional finance centers in Chinese mainland; encourage more qualified institutional investors; reposition the market relations among Hong Kong, Shanghai and Shenzhen; and increase deregulation and internationalization to speed up the integration of financial resources.     

ON THE RAND: DETERMINANTS OF THE SOUTH AFRICAN EXCHANGE RATE

This paper is an econometric investigation of the determinants of the real value of the South African rand over the period 1984‐2007. The results show a relatively good fit. As always with exchange rate equations, there is substantial weight on the lagged exchange rate, which can be attributed to a momentum component. Nevertheless, economic fundamentals are significant and important. This is especially true of an index of the real prices of South African mineral commodities, which even drives out real income as a significant determinant. An implication is that the 2003‐2006 real appreciation of the rand can be attributed to the Dutch Disease. In other respects, the rand behaves like currencies of industrialised countries with well‐developed financial markets. In particular, high South African interest rates raise international demand for the rand and lead to real appreciation, controlling also for a forward‐looking measure of expected inflation and a measure of default risk or country risk.     

VARIANCE RATIO TESTS OF THE RANDOM WALK HYPOTHESIS FOR SOUTH AFRICAN STOCK FUTURES

The hypothesis that stock futures follow a random walk is tested for four stock index futures and a sample of 36 single stock futures traded on the JSE Securities Exchange, South Africa, using joint variance ratio tests based on (i) ranks and signs and (ii) wild bootstrapping. Overall, there is a high degree of weak‐form efficiency: all four stock index futures and twenty‐five of the sample of 36 single stock futures follow a random walk.     

THE EFFECT OF STRESSED ECONOMIC CONDITIONS ON SYSTEMIC RISK WITHIN THE SOUTH AFRICAN BANKING SECTOR

The credit crisis resulted in increases in credit, market and operational risk, but it may also have precipitated a surge in systemic risk. Measuring systemic risk as the price of insurance against distressed losses in the South African banking sector, this article attempts to determine whether the financial crisis has in fact resulted in an increase in systemic risk. Using probabilities of default and asset return correlations as systemic risk indicators, it is found that the financial crisis has indeed increased systemic risk in South Africa. The impact was, however, less severe than that experienced in other large international banks.

Testing the nexus between renewable energy consumption and environmental quality in Nigeria: The role of broad‐based financial development

This study investigates the nexus between renewable energy consumption and environmental quality in Nigeria, accounting for the role of financial development, and re‐examines the validity of the environmental Kuznet curve (EKC) hypothesis for Nigeria covering the period 1990 to 2016. To cover financial development more adequately, the current study uses the broad‐based financial development index constructed by the International Monetary Fund. The study employs second generation econometric approaches of Lee and Strazicich, and Bayer and Hanck combined cointegration tests to check for stationarity and cointegration among the variables, and then applies autoregressive distributed lag (ARDL) and vector error correction model (VECM) Granger causality tests to explore the effect and causal relationship respectively. The results divulge that renewable energy consumption improves environmental quality, while financial development hurts the environment. Further, the results validate an inverted U‐shaped association between economic growth and environmental degradation in Nigeria. The VECM Granger causality results indicate a long‐run effect of the independent variables on CO₂ emission, while the short‐run causality reveals a mixture of unidirectional and bidirectional causality among the variables. This study therefore recommends that policy makers consider the important roles of renewable energy and financial development in reforming energy policies to achieve environmental sustainability.
