Firm investment behavior: the role of leverage, liquidity and cash flow volatility: African evidence.
Full text linkDoctoral degree. University of KwaZulu-Natal, Durban.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
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Unveiling the Role of Investment Tangibility on Financial Leverage: Insights from African-Listed Firms
No full textThe asset structure of a firm plays a pivotal role in determining its leverage. A higher proportion of physical assets is often associated with high debt ratios. This study explores the impact of investment tangibility on financial leverage, examining both tangible and intangible investments. Using a dynamic panel data model estimated through the two-step system generalized method of moments (GMM), we analyse a dataset encompassing 815 non-financial listed firms from 22 African stock markets. The results show that African firms have higher inclinations to invest in physical assets. We found a statistically significant negative relationship between leverage and tangible and intangible investments. The findings indicate that African firms tend to maintain lower leverages regardless of whether they invest in tangible or intangible assets. The observed relationship aligns with the hypothesis that high-growth firms, in their expansion efforts, strategically tend to opt for low debt to mitigate the agency costs associated with debt and to help prevent underinvestment. This outcome underscores the interconnected nature of financing and investment decisions. This research contributes to the literature on financial leverage and investment by dissecting investments into tangible and non-tangible components and highlighting their distinct impacts on leverage. Moreover, it provides empirical evidence for previously unexplored African firms, shedding light on the reasons behind the relatively low leverage levels observed in African firms
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
COVID-19 Shock and Sectorial Index Response in South Africa: A Cross-sector Analysis
No full textThe prime objective of this study was to examine the impact of COVID-19 shock on sector returns of the South African Stock market. The study employed the Autoregressive Distributed Lag (ARDL) model estimated with a Pooled Mean Group estimator on a sample of daily stock returns of 10 Johannesburg Stock Exchange (JSE) sectors. The results indicate a heterogeneous behaviour in sector stock return response to COVID-19 shock. The study shows that the Pandemic negatively impacted the majority of the sectors. However, some sectors were positively affected by the outbreak, while some were resilient to the shock. The pooled ARDL panel results show a negative relationship between COVID-19 and stock market returns in the short run. The study found an insignificant relationship between stock market returns and COVID-19 cases in the long run. The study also shows that sector and stock return response to different factors is time-varying. The results imply that COVID-19 shock is short-lived, the negative impact of the Pandemic is corrected in the long run. Stock market investors should thus focus on the long-run behaviour of stock returns. The results evidence the significance of diversification in different stock market sectors for investors</jats:p
The impact of leverage on discretionary investment: African evidence
No full text
Purpose
The purpose of this paper is to explore the impact of leverage on firms’ discretionary investment in Africa.
Design/methodology/approach
The authors employ a dynamic panel data model estimated with generalised method of moments (GMM) estimation techniques on the panel data of listed African non-financial firms. A dynamic model and the generalised methods of moments estimations are handy in controlling for unobserved heterogeneity, endogeneity, autocorrelation, heteroscedasticity, etc.
Findings
In spite of different settings, markets, leverage levels and methodologies, the authors found evidence that leverage constrains investment in African firms. The negative impact is more pronounced in firms with low-growth opportunities than in firms with high-growth opportunities. The results are inclined to the theory that leverage plays a disciplinary role to avoid overinvestment.
Research limitations/implications
African firms’ investment policy does not solely depend on the neoclassical fundamentals determinants of profitability, net worth and cash flows. Financing strategy also has a considerable bearing on the investment policy. The results provide evidence that leverage is a negative externality to the firm’s discretional investment policy for both lowly levered and highly leveraged firms. African firms’ should consider maintaining their low debt levels and rely more on internally generated funds so as not to suppress any available cash flows to interest payments and loan covenants from debt holders.
Originality/value
The study contributes to the literature on investment and financial leverage by the authors providing evidence from Africa, a developing continent, that has not been explored. It shows how conservative leverage levels of African firms, which have been reported to be rising, are impacting on investments. Pertaining to empirical methodology, the authors employ a dynamic panel data model, the GMM estimation technique, which is robust in controlling endogeneity, and a possible bi-directional causality between leverage and investment which have not been used in literature. The study also enables a comparison of the effect of high leverage and low leverage on firm’s discretional investment.
