Firm investment behavior: the role of leverage, liquidity and cash flow volatility: African evidence.
(2017) Edson, Vengesai.; Kwenda, Farai.
The main corporate financial strategic pillars that drive a firm’s value are mainly financing and investment. Conventional finance theories hold that leverage is power that amplifies investment. Cash flows and liquidity are the lifeblood of any firm which gives life to and fuels higher investments. To this end, there is an indispensable interplay between financing, investment, cash flows and liquidity. Existing studies on investment decisions are largely centered on developed economies but no studies, to the best of my knowledge, have been done in developing economies like those in Africa. However, there is persistent behavioural and structural heterogeneity between firms in developing and developed economies, resulting in diverging economic implications for a firm’s behaviour. This study was motivated by the observation that leverage levels in African firms are generally low but now on the rise as compared to developed economies, investment levels are stagnant, low liquidity of stock markets coupled with cash flows that are too volatile. Given the progressively vital role developing economies have for global growth, this study sought to find how this trend in leverage levels is impacting on investment in Africa, a concern for the global economy. Given the inseparability of investment and leverage from liquidity and cash flow, the study also examines the role of liquidity and cash flows in investment decision making. This study extends the reduced form investment model to a dynamic panel data model estimated with a novel technique; the generalised method of moments (GMM) on the panel data of 815 listed African non-financial firms. The methodology controls for unobservable heterogeneity, endogeneity, autocorrelation, heteroscedasticity and probable bi-directional relationships. The study found evidence that leverage constrains investment and its impact is more pronounced in firms with low-growth opportunities. These results suggest that investment policy does not solely depend on the neoclassical fundamentals but also on financing strategy and are inclined to the hypothesis that leverage plays a disciplinary role to avoid over-investment. The study also found that stock market liquidity is associated with higher average capital expenditures. The effect of liquidity on investment was found to be heterogeneous with financial constraints and growth opportunities. The study reveals that cash flows are not only an important determinant of investment decisions, but the variability of the cash flows also has a significant bearing on the investment policy. The experimental analysis shows that an increase in debt may reduce the negative effect of leverage on investment. However, the shallow, illiquid debt markets of African firms would mean higher costs and this countermands any benefits from debt. Based on these, findings, the study recommends that African firms should consider relying more on internally generated funds and the stock markets so as not to suppress any available cash flows and improved liquidity. African firms should trade off the effects of managing volatility and the resulting negative impact of cash flow volatility on investment levels.
Institutional shareholders' monitoring and control over corporate decisions: evidence from JSE listed companies.
(2021) Obagbuwa, Oloyede.; Kwenda, Farai.
This thesis seeks to intensify our understanding of the responsibility of the institutional shareholders in corporate governance. Whereas several studies have investigated the efficacy of institutional shareholders' monitoring and have considered the diversity of their investment, there is a dearth of research on the effect of limited attention caused by distraction on their monitoring intensity and particularly on the reaction of the corporate executives regarding corporate decisions to the temporarily relaxed monitoring intensity in emerging market space. As a result of a shift in institutional shareholders' attention occasioned by exogenous shocks to an unrelated firm in their portfolios, the intensity of their monitoring of corporate activities dropped. The executives make decisions beneficial to them and harmful to institutional shareholders' interest and the firm's value. The study considers corporate decisions on executive remuneration, earnings management, investment inefficiency and mergers and acquisitions (M&A). These decisions are crucial to the growth of firms and return to institutional shareholders. However, due to agency problems, corporate executives' decisions on these activities tend to be for personal interest at the detriment of institutional shareholders' interest and firm value. Effective institutional shareholders' monitoring seems to be the antidote against opportunistic executives. But the intensity of their monitoring is affected by distraction caused by the external shocks to another firm in their portfolios. When this distraction occurs, the executives maximise the space to make decisions on their remuneration, manipulate earnings, invest in the unprofitable venture, and uncontrolled acquisition sprees that is of private benefits. The first empirical analysis in this thesis examines the impact of institutional shareholders' distraction on executive remuneration. The study shows that when shareholders are distracted and their monitoring intensity drops, the executives are inclined to manipulate their remuneration without considering institutional shareholders' interest and firm performance. The second empirical analysis examines the relationship between the relaxed institutional shareholders' monitoring intensity and executive decision on earnings management. The study reveals that the executives tend to manipulate both the discretional accruals earnings and real activities earnings for personal interest. The third empirical analysis indicated that executives could invest in projects with negative net present value (NPV) when the institutional shareholders monitoring is not sufficient. The final empirical research relates to the intensity of institutional shareholders’ monitoring to M&A executive decisions. The finding reveals that the executives could engage in an uncontrolled acquisitions spree of personal interest, jeopardise institutional shareholder’s investment and fail to improve the firm's value. The overall findings indicated that when institutional shareholders' attention is shifted, their monitoring intensity drops. The executives engage in corporate decisions that will not be in the shareholders' best interest and promote the firm's growth. These findings support the hypothesis that institutional shareholders monitoring intensity has a positive influence on corporate decisions. This insight has an implication for stakeholders and value-creating corporate governance mechanism. The study employed the more robust Generalised Method of Moments (Sys-GMM) estimation approach to analyse the data collected for firms listed on the Johannesburg Stock Exchange (JSE) covering the period 2004-2019.
Liquidity management practices of banks in emerging market economies under Basel III liquidity regulations.
(2017) Mashamba, Tafirei.; Kwenda, Farai.
During the 2007 to 2009 global financial crisis, several banks experienced liquidity problems, largely as a result of liquidity management practices they pursued prior to the crisis. In an effort to strengthen banks’ liquidity management practices, the Basel Committee on Banking Supervision announced harmonized and binding liquidity requirements for banks in December 2010 under the Basel III framework in the form of the Liquidity Coverage Ratio (LCR) and Net Stable Funding Ratio (NSFR). The LCR aims to enhance banks’ short term resilience to liquidity stress lasting 30 calendar days by requiring them to maintain sufficient stock of high quality liquid assets. The NSFR seeks to limit banks’ asset and liability mismatch by demanding them to maintain a balanced funding mix that is commensurate with their asset base and off-balance sheet activities. Thus, liquidity standards are deliberately aimed at affecting banks’ liquidity management practices. However, the new liquidity regulations introduced by the Basel Committee on Banking Supervision may bring a new source of intertemporal assets and liabilities choices that are currently absent in banks’ decision making processes. Moreover, as with all regulations, liquidity standards may or may not produce their expected goals. Accordingly, this study sought to examine the impact of the Basel III liquidity standards, in particular, the LCR which is now binding on liquidity management practices of banks operating in emerging market economies. Employing the two-step system Generalised Method of Moments estimation technique on a panel dataset of forty commercial banks operating in eleven emerging market economies over the period 1 January 2011 to 31 December 2016, the results obtained revealed that banks in emerging market economies have target liquidity ratios they pursue and partially adjust their liquidity due to financial frictions. Furthermore, the study established that the Basel III LCR liquidity regulation complemented liquidity management practices of banks in emerging markets. In terms of the behavioral response of banks in emerging markets to liquidity standards, the study found that, on the asset side, banks in emerging markets appear to have elevated their stock of high quality liquid assets and on the liability side, it seems banks in emerging markets increased retail deposits, equity and long term funding. Moreover, empirical results demonstrated that the LCR charge did not adversely affect the profitability of banks in emerging markets. Among other things, these findings suggest that the LCR liquidity regulation is less effective in jurisdictions with high liquidity reserves. In addition, changes in banks’ funding mix caused by regulatory pressure stemming from the LCR rule may lead to stiff competition for retail deposits among banks. The study therefore recommends that regulators and policy makers should monitor competition for retail deposits to prevent reversal of financial sector stability gains achieved by the liquidity regulations. The study also advocates for the adoption of the Basel III liquidity standards in jurisdictions with commercial banks that depend more on capital markets for funding.
The nexus between mobile phones diffusion, financial inclusion and economic growth: evidence on African countries.
(2018) Chinoda, Tough.; Kwenda, Farai.
The following thesis comprises three discrete empirical essays on the interplay among mobile phones diffusion, financial inclusion and economic growth in Africa. The first essay examines the condition of financial inclusion and its determinants in Africa. Using the World Development Indicators and the Principal Component Analysis to compute the financial inclusion index for 49 African countries over the period 2004 to 2016, the study finds low levels of financial inclusion in Africa compared to other regions. The region is also characterised by large financial inclusion gaps as shown by the minimum and maximum financial inclusion levels of 0 percent and 82 percent respectively. Since policymakers have over the past decade embraced both financial inclusion and economic growth as key policy initiatives, the second essay examines the interplay between financial inclusion and economic growth in terms of the transmission effect and nature of causality. To the best of the researcher’s knowledge, this is the first study to explore the transmission effect between financial inclusion and economic growth using a unique and robust Cointegrated Panel Structural Vector Autoregressive model. The study finds the existence of a cointegrating relationship between financial inclusion and economic growth. It also provides evidence that the relationship between financial inclusion and economic growth in Africa is growth-led supporting the demand following hypothesis. The increased internet-enabled phones adoption in Africa has also caused much optimism and speculation regarding its effects on financial inclusion. Policymakers, various studies and the media have all vaunted the potentials of mobile phones for financial inclusion. Therefore, this study examines the interplay between mobile phones and financial inclusion in Africa for the 2004-2016 period using pairwise Granger causality test and found that mobile phones Granger cause financial inclusion. The literature on financial inclusion has identified high-quality institutions and governance as the determinants of financial inclusion. Lack of deeper understanding of these issues results in ill-informed policy designs. Despite the cascading literature on issues impacting financial inclusion, the empirical literature on the impact of institutional quality and governance on financial inclusion are rare. Therefore, the third essay evaluates the impacts of institutional quality and governance on financial inclusion in Africa. Applying the two-step system generalised method of moments model, the study finds a positive relationship between institutional quality, governance and financial inclusion, indicating that good governance and economic freedom can lead to increases in financial inclusion. The study concluded that African countries have low levels of financial inclusion with a strong relationship between financial inclusion and other variables such as mobile phones diffusion, bank competition, financial stability, institutional quality and governance. The study recommended institutions to make the most out of the high concentration of the rural population to rollout high-volume transactions, rather than clustering in areas with the high-value transaction and to craft policies that remove restrictions to entrance in the banking sector thereby enhancing bank competition. Policymakers should also not just focus on enhancing financial inclusion, without corresponding improvements in institutional quality, governance, financial sector size, financial stability and financial sector development as they positively contribute to financial inclusion. The study also recommended the implementation of pro-growth policies and a review of existing banking sector policies to eradicate unnecessary barriers to financial inclusion.
