    The capital structure variations across industries of listed South African firms during boom and bust cycles
    (2014-07-10) Nel, Matthew
    Capital structure is the varying levels of use of debt and equity to finance a firms operations. Firms have an overall leverage level, consisting of a long term and short term level. The economy has different phases over the business cycle ranging from boom cycles where businesses prosper to recessions when they may have difficulties. This cycle can be identified utilising economic indicators, the South African Reserve Bank has classified time periods into growth and recessionary periods, this business cycle phase allocation was utilised for this study to mark recessions. Specific industries from the JSE were selected in an attempt to answer the study’s hypotheses of industry capital structure heterogeneity and that recessions affect capital structure. A sample period from 1995 until 2012 was utilised, containing 5 recessionary years. A stable industry, farming and fisheries, a highly variable industry, the heavy construction industry and a new age industry, the computer services industry, were selected. The results of the study suggested that capital structure varies across industries as evidenced by the mean differences of leverage for total debt, long term debt and short term debt being statistically significant. The computer services industry utilised the least debt over all. The industries all showed a preference for the use of short term debt. Panel data analysis following both Fixed Effect Methodology and Random Effect Methodology was conducted to analyse the firm-specific factors which affect capital structure as well as the use of a dummy variable to capture the effects of recessions. The firm-specific effects under study included asset tangibility, tax, profitability, age and size. South African firms follow a pecking order as shown by the negative relationship observed between profitability and long and short term debt ratios. Existence of weak evidence in this study shows that recessions affect the capital structure of some of the industries studied. The computer services industry is clearly affected, while farming and fisheries industry has very weak evidence that long term debt may be affected, while there is no evidence to show that the heavy construction industry is affected at all. The study concluded with accepting the hypothesis that there are capital structure variations across industries, which are listed on the JSE in boom and bust periods.

    Institutional dynamics and impact on capital formation: evidence from Namibia and Tanzania
    (2013-03-15) Zaaruka, Benethelin P.
    The purpose of this thesis is to examine the impact of institutions on fixed capital accumulation over time in two developing countries, both former German colonies: Namibia and Tanzania. This is motivated by two recent underpinning theories: the new institutional theory, which views institutions as fundamental determinants of economic outcomes and income variations among countries (the institutional hypothesis); and the theory of irreversible investment under uncertainty, which emphasis the impact of uncertainty on investment and capital-stock accumulation. The first part of the thesis deals with the measurement and definitions of institutions. Empirical measures of political and economic institutions have been previously produced; however, most cover short periods of time. The short time span of the institutional indices makes them practical in cross-countries and panel studies, rather than in country-specific studies. The importance of country-specific studies is underscored by the notion that different historical paths led to different ways of organising economic activities and political structures, yielding the differences in economic development across countries. To overcome this challenge, this thesis presents a database on institutional measures for Namibia and Tanzania for the period 1884 to 2009. These indicators are used to assess the nature of political and economic institutional transformation from the colonial legacy to the modern outcome, using Namibia and Tanzania as a natural experiment. Relying on archival information on formal laws in Namibia and Tanzania, the thesis constructs institutional indicators that are de jure in nature representing political freedom, property rights and judicial independence. These allow for the assessment of rules the game, rather than outcome. The formal codification of rights and freedoms is of little significance if those rights cannot be enforced. Therefore, the de facto element is also considered through the construction of separate indicators on political instability and judicial independence. A clear theoretical framework on each indicator provides the selection and combination of each sub-component. A meaningful composite measure is based on the techniques of principal components and factor analysis. v The thesis argues that despite changes in colonial identity in these countries (i.e. German, then British or South African), the broader framework of institutions remained partly the same, particularly in the case Namibia. It is true that, with the attainment of independence in Namibia, many institutions did change, particularly in the areas of political freedom, and judicial and political instability. Measures such as property rights, on the other hand, are slow to change. However, the overall long-lasting effect of these colonial institutions on economic outcomes remains an empirical question. Similarly, the case of Tanzania reflects the notion of institutional persistence as the country continued to undermine political freedom even after the attainment of independence. Tanzania is among the few countries which adopted a constitution without a bill of rights at independence. Also, the new indicators for both countries, while covering a long time period (1884–2009), correlate fairly well with some of the widely used institutional indices produced by Freedom House and the Heritage Foundation. The second part of thesis establishes the impact of institutional variables on capital accumulation in Namibia and Tanzania, applying the Johansen Vector Error Correction Model (VECM) technique. The data span for Namibia is from 1923 to 2009, and that for Tanzania is from 1946 to 2009. The findings highlight the importance of uncertainty (political instability) in explaining capital accumulation over time in Namibia. The results also show that other institutional variables are important in explaining uncertainty. Rising levels of property rights and political rights lower political instability in Namibia. The empirical evidence for Tanzania indicates the importance of property rights in explaining capital accumulation over time. The most interesting result is the importance accorded to the judicial independence, which showed a positive correlation to gross domestic product (GDP). It is also shown that other institutional variables (property rights and political rights) have a positive correlation to judicial independence. A further finding is that uncertainty (political instability) has a negative effect on economic development over time in Tanzania.

    Internationalisation of South African SMMEs: the role of capital factors.
    (2013-02-18) Shree, Sanam.
    The purpose of this paper is to investigate the influence of capital factors on the internationalisation of South African Small Medium and Micro-Enterprises (SMMEs). These capital factors are Financial, Social and Human capital. The study concentrates on determining how various levels of capital act as a preventative factor when a firm internationalises. The low levels of Financial capital is accentuated as it prohibits South African SMMEs from internationalising. Social capital emphasises that few social ties and networks prevent South African SMMEs from globalising. Lastly, the focal point of Human capital are the low levels of international knowledge and experience of management, which prohibits South African SMMEs from expanding internationally. To address these issues, this study draws upon a sample of 136 South African internationalised and non-internationalised SMMEs studied via an online questionnaire. The major theories underlying this research include the Resource-based theory, the Social Network theory and the Organisational Learning theory. Multivariate statistical analysis were used to test the results and confirmed that Financial Funding had an influence on an organisation’s ability to internationalise. Results from this study can potentially provide policy-makers and practitioners with additional insights into the key constraints to internationalisation of South African SMMEs.

    Capital and debt maturity structures of a firm: evidence from selected African countries
    (2012-07-04) Lemma, Tesfaye Taddese
    The thesis examines the influence of institutional, macroeconomic, industry and firm characteristics on financing decisions of firms in nine select countries in Africa. It develops a battery of econometric models and examines 10 year (1999-2008) data pertaining to 986 non-financial firms and sample countries using various estimation procedures. The results suggest that financing decisions of firms in Africa is not only determined by firm characteristics (such as firm size and profitability, growth opportunities, asset tangibility and/or maturity, earnings volatility, dividend payout and non-debt-related tax-shield) but also by industry, macroeconomic (income group of the country, size of the overall economy and its growth, inflation and taxation) and institutional (legal origin, investor rights protection and law enforcement) factors. The research also demonstrates that firms in Africa face adjustment costs and/or benefits in rebalancing their capital and debt maturity structures to the optimal and such costs depend on select firm, industry, macroeconomic and institutional factors. Our findings signify that firms in Africa are concerned about transaction, agency and bankruptcy costs; information asymmetry and adverse selection problems; financial flexibility and access to finance issues; tax regimes, investor rights protection and law enforceability, among others in making their financing decisions. It is strongly recommended that governments, policy makers, and other stakeholders should pull their efforts together to come up with legislations, policies and directives that enhance investor rights protection and law enforcement which will in turn boost the confidence of market participants. The study also recommends that governments should use interest rate restraints and reserve and liquidity requirements to enhance financial deepening which will in turn enhance investors’ confidence.

    The effect of macroeconomic conditions on the capital structure adjustment speed of South African listed firms
    (2012-06-29) Krishna, Sudha
    This paper uses a two-stage, dynamic partial adjustment model which accounts for potential mean-reversion, with the Arellano-Bover GMM estimation technique, to observe the effect of various macroeconomic variables on the speed at which South African listed firms adjust toward their target capital structures. Employing two definitions of financial constraints, these effects were also compared for financially constrained and unconstrained subsamples. Using a sample of listed firms spanning from 2000 to 2010, the findings of the study show some indication that firms adjust faster in unfavourable macroeconomic states relative to favourable states. There is also evidence to suggest that the adjustment dynamics of unconstrained firms differ from that of constrained firms. In addition, higher adjustment speeds are generally observed when using short-term debt relative to other debt definitions. However, the evidence is largely inconclusive as adjustment speed estimates are highly sensitive to the definition of financial constraints used, and to the inclusion of extreme leverage observations.
