External Debts,Institutions and Growth in SSA

The study investigates the impact of institutional quality on the external debt–growth nexus in SSA. Data from 36 SSA economies over the 1996–2013 periods were used. The results from the IV-System GMM imply that institutional quality has robust effects on the external debt–growth nexus. Thus, the impact of external debt on growth is through host nation’s institutional quality. However, the mediating effect of institutional quality on this nexus is up to a point. When a country is on the wrong side of the debt-laffer curve, external debt becomes irrelevant; and institutional quality can no longer help.     

Expansion and Efficiency in Banking: Evidence from Ghana

We use a translog functional form to estimate a stochastic frontier function of cost and profit efficiency (PE) of Ghanaian banks under the Battese–Coelli time‐varying decaying inefficiency parameterization for (unbalanced) panel data. We regressed efficiency estimates on a distance variable controlling for bank size, total cost, and profits. We find that Ghanaian bank PE is worsening, whereas cost efficiency is improving for the period analyzed. Our results show that PE is not related to distance, size, or cost and profitability ratios. Distance is however positively and significantly related to cost efficiency. Cost efficiency is however not influenced by size or cost and profit ratios.

A socio‐economic assessment of cowpea diversity on the Ghanaian market: implications for breeding

Given the importance of cowpea [Vignaunguiculata(L)Walp] in fighting malnutrition and poverty, a socio‐economic assessment of cowpea diversity found on the Ghanaian market was conducted. The objective was to investigate emerging consumer preference for cowpea and make recommendations for the development of tailor‐made varieties. Forty‐seven cowpea accessions were collected from traders interviewed for morphological characterization to ascertain the degree of diversity. Data was subjected to Hierarchical Cluster Analysis using Genstat Discovery Edition 3 software and variations among the cowpea varieties based on the selected seed traits established. Cowpea varieties found on the markets were broadly categorized into foreign and local varieties and usually named after their sources. Foreign Cowpea varieties were very popular on the markets surveyed as reflected in the per cent distribution of respondents by cowpea varieties sold; Niger (52%), Burkina Faso (50%), Togo (46%), Lagos (36%) and Ghana (18–21%). At the trader level, the order of preference for cowpea characteristics was cleanliness (stone free and no dirt), colour (white seed colour), easy to cook, taste, size, less weevil damage, dryness and place of origin ranked in decreasing order of importance. At the consumer level, cleanliness that was also tied to the extent of weevil damage was ranked most important. This was followed by seed colour (preferable white), short cooking time, size and taste. From the sociological perspective, concerns are raised on the impact of past cowpea breeding activities giving the level of competitiveness and market performance of locally improved varieties observed. Recommendation is made for traders and consumers to be considered as relevant actors in all the stages of crop improvement and breeding activities. This is crucial for enhanced small‐holder farmer market access and strengthened food networks in rural economies.     

Executive compensation and firm risk after successful mergers and acquisitions in Africa

This paper examines the impact of various executive compensation types on the postmerger risk taking by firm's executives. We find that executive pay influences firm risk differently depending on compensation type and risk measure. Specifically, we find that rewarding executives with cash compensation reduces the total postmerger risk of acquirers. However, managers are motivated to increase systematic risk when they are rewarded with stock‐based incentives. Besides, based on the argument that managerial compensation portfolio might impact systematic and unsystematic risks differently, our findings show no evidence of the impact of executive pay on unsystematic risk.     

Product differentiation,market dynamics and the value relevance of trade payables: Evidence from UK listed firms

This paper provides a comprehensive evidence on how product and market dynamics affect the value relevance of trade payables. Using a sample of 2559 UK listed firms over the period 2005–2014, we find a positive relationship between trade payables and firm performance. Our evidence suggests that trade payables increase (decrease) performance in firms with differentiated products and demand uncertainty (larger market share). We demonstrate that the relative value relevance of bank credit versus suppliers’ credit is dependent on the nature of the product, the level of sales volatility, and market share. We use an innovative approach to assess the robustness of our results to omitted variable bias.     

Feedback Trading and Autocorrelation Patterns in Sub-Saharan African Equity Markets

This article examines feedback trading and autocorrelation pattern of stock returns in the equity markets of Ghana, Kenya, Nigeria, and South Africa. We find evidence that positive feedback trading induces negative autocorrelation in the stock returns of Ghana, Kenya, Nigeria, and South Africa. The negative autocorrelation occurs during periods of increasing volatility, and all the four equity markets exhibit volatility asymmetry. We also find that Ghana, Nigeria, and South Africa were influenced by the 2008–2009 global financial crisis, and South Africa experienced the largest impact. These findings may have implications for risk management and price discovery in these equity exchanges.     

Creating space for innovation—The case of mobile telephony in MSEs in Ghana

Mobile telephones have become important tools for socio-economic activities. In Africa, their diffusion is phenomenal. This paper adopts the innovation system conceptual framework for analyzing the state of mobile telephony in Ghana, the trends and implications for enhancing benefits. The paper emphasizes the role of the critical actors, and the internal and external environments they operate in. It uses primary and secondary data in analyzing the real and potential innovative use of mobile telephones by the MSEs in Ghana. It also examines the range of applications of mobile telephones in the MSEs, and assesses current public policies and the outcomes of such policies on innovations in MSEs. Finally, it advocates for a more holistic promotion of innovations from the broad perspectives. Efforts to stimulate innovation must be on the demand side of innovation as well as on the supply side.     

Corporate voluntary greenhouse gas reporting: Stakeholder pressure and the mediating role of the chief executive officer

The study sheds light on the extent to which various stakeholder pressures influence voluntary disclosure of greenhouse gas (GHG) emissions and how the impact is explained and moderated chief executive officer (CEO) characteristics of 215 FTSE 350 listed U.K. companies for the year 2011. The study developed a classification of GHG emission disclosure based on the guidelines of GHG Protocol, Department for Environment, Food and Rural Affairs, and Global Framework for Climate Risk Disclosure using content analysis. Evidence from the study suggests that some stakeholder pressure (regulatory, creditor, supplier, customer, and board control) positively impacts on GHG disclosure information by firms. We found that stakeholder pressure in the form of regulatory, mimetic, and shareholders pressure positively influenced the disclosure of GHG information. We also found that creditor pressure also had a significant negative relationship with GHG disclosure. Although CEO age had a direct negative effect on GHG voluntary disclosure, its moderation effect on stakeholder pressure influence on GHG disclosure was only significant on regulatory pressure.

Financial Access and Firm Productivity in Sub-Saharan Africa

The paper investigates the effect of access to finance on the productivity of manufacturing firms in Sub-Saharan Africa. With the aid of the Semi-parametric approach by Levinsohn and Petrin, findings reveal that access to a cost-effective line of credit/loan or an overdraft facility has a positive effect on firm productivity. The study, therefore, concludes that it is of outmost benefit for firms to acquire credit facilities for more productive projects and that the credit constraints firms in Africa face should be significantly relaxed.
