Item Agricultural Export, Growth and the Poor in Africa: A Meta Analysis(Journal of Interdisciplinary Economics, 2022) Adeabah, D.; Asongu, S.Over the past decade, a growing number of studies have examined the role of agricultural export in economic growth in Africa. The literature, however, provides conflicting results about the agricultural export-led growth hypothesis. In this study, we aim to re-examine the impact of agricultural export on economic growth by performing a meta-analysis. There are two questions of interest, namely, (a) whether publication bias is present in the agricultural export-growth literature in Africa, and (b) if there is an overall effect of agricultural export on economic growth. Our meta-analysis finds significant negative publication bias in the literature. Moreover, after correction for publication bias, the results show that agricultural export leads to growth in low-income and lower middle-income African countries. These results are consistent with the agricultural export-led growth hypothesis. By this, we provide empirical basis that may enhance policy decisions on resource allocation to areas of comparative advantage. Additionally, the existence of an income differential effect on the agricultural export-led growth nexus implies that agricultural export-growth strategy has a pronounced effect on the poor in Africa. The result suggests that the poor in Africa could follow an agricultural growth strategy because it is a promising means to increase per capita wealth.Item Agricultural Export, Growth and the Poor in Africa: A Meta Analysis(Journal of Interdisciplinary Economics, 2022) Adeabah, D.; Asongu, S.Over the past decade, a growing number of studies have examined the role of agricultural export in economic growth in Africa.

In that regard, this study presents a comprehensive overview of the dominant barriers encountered by agribusinesses to ensure long-term success through the lenses of a literature review. Design/methodology/approach – The study used a systematic literature review (SLR) of 43 relevant articles. The study applies content analysis to identify and analyze the selected articles. The conceptual framework underlines the three principal barriers to sustainable agribusinesses. Findings – The results from the SLR demonstrates that inadequate financial support, excessive post-harvest loss, gender inequality, non-climate-smart policies and weak institutional controls constitute the major challenges to the sustainability of agribusinesses. Research limitations/implications – The study is limited in scope to barriers to the sustainability of agribusiness only not the broad spectrum of the concept of agriculture. Originality/value – This study’s uniqueness is twofold. First, it provides a checklist for practice with the goal of addressing problems that hamper the sustainability of agribusinesses. Second, the findings and research gaps in this study are important to support future studies.Item Board gender diversity, corporate governance and bank efficiency in Ghana: a two stage data envelope analysis (DEA) approach(Corporate Governance (Bingley), 2018-10) Adeabah, D.; Gyeke-Dako, A.; Andoh, C.Purpose This study aims to analyze the efficiency of banks under board gender diversity and to examine the determinants of bank efficiency. Design/methodology/approach Data for analysis were sourced from annual reports of 21 banks for the period from 2009 to 2017. A two-step framework was used: first, an examination of efficiency scores with and without board gender diversity computed using data envelopment analysis; and second, a regression of board gender diversity as a determinant of bank efficiency using panel estimation on an unbalanced panel data. Findings The results reveal that gender diversity promotes bank efficiency up to a maximum of two female directors on a nine-member board of directors, suggesting a threshold effect on bank efficiency. Board size improves bank efficiency. Board independence is negatively related to bank efficiency. Also, powerful chief executive officers are detrimental for bank efficiency. Finally, the authors find that ownership structure, bank size, bank age and loan-to-deposit ratio are important factors affecting bank efficiency. Research limitations/implications All bank-year observations with no female representation on the board were excluded. As such, this paper is limited to 21 banks. Future research should look at a larger data set and account for dynamic endogeneity. Practical implications The paper contributes to bank governance structure, namely, gender composition of boards, and provides an insight for regulators and shareholders to estimate the role of men and women on boards. Originality/value The novel feature of the efficiency model used is that it incorporates board gender diversity as an additional input variable, in line with the preposition of proponent of resource dependency theory.Item Remittances, ICT and pension income coverage: The international evidence(Technological Forecasting & Social Change, 2021) Adeabah, D.; Asongu, S.; Andoh, C.This study examines the impact of remittances and information and communication technology (ICT) on pension at the country level. Our empirical evidence, based on data from 96 countries, indicate a significant non-linearity between remittances, ICT and pension income coverage. First, we find a convex relation between remittances and pension income coverage, indicating that increases in remittance, initially decreases pension income coverage, but as remittance increases beyond a certain point, so too does pension income coverage. This inflection point, where the effect of remittances turns from negative to positive, is estimated to be around 3.09% of GDP. Second, we document a concave relationship between ICT (i.e. mobile subscription and internet penetration) and pension income coverage. An increase in ICT results in increased pension income coverage. However, when ICT reaches a certain point, any further increase is associated with lower pension income coverage. The estimated optimal point is found to be around 140.14 subscriptions (per 100 people) for mobile phone and 27.93 (per 100 people) for internet penetration, respectively. Other implications are discussed.Item Reputational risks in banks: A review of research themes, frameworks, methods, and future research directions(Wiley, 2022) Adeabah, D.; Andoh, C.; Asongu, S.; Gemegah, A.This study examined the research trends on reputational risk in banks using a systematic literature review and network analysis (SLRNA) approach on 35 research articles published between 2010 and 2020. It was found that only developed countries (i.e., the United States and Europe) have been actively contributing to research on reputational risks in banks, suggesting that reputational risks management of banks has not gained the global attention it deserves. Moreover, we identified five broad research themes from the thematic network analysis, namely, reputational risk of operational losses, reputational effects of media tone, performance implications of reputational risk management, management of reputational risk in banks, sustainability practices and reputational risk of banks in the project finance market. Nonetheless, there still a number of areas that require further attention. These include conceptualization of reputational risk management in banks that explore the dynamic and interdependencies in a system thinking framework, the role of corporate governance, environmental and social issues on reputational risk, how sustainability practices shape reputational risk management, the role of political connections in mitigating reputational effect of operational loss events, and how information and communication technology (ICT) mechanisms impact reputational risk management in banks.Item Reputational risks in banks: A review of research themes, frameworks, methods, and future research directions(Journal of Economic Surveys, 2023) Adeabah, D.; Andoh, C.; Asongu, S.; Gemegah, A.This study examined the research trends on reputational risk in banks using a systematic literature review and network analysis (SLRNA) approach on 35 research articles published between 2010 and 2020.

In this study, existing studies on green finance in the context of the banking sector have been reviewed with considerations on products and determinants of green finance. The content analysis approach has been used to critically analyse and summarize forty-six (46) relevant studies. The results found green securities, green investments, climate finance, carbon finance, green insurance, green credit and green infrastructural bonds as part of key green finance products of banks. Pertinent determinants the study found to be influencing green finance policies from banks include environmental and climate change policies, interest rates, religion, risks, social inclusion and social justice as well as banking regulations. In theory, this study provides a guide for further studies. The results of the study will assist banks on the key issues to consider in adopting, developing and granting green finance.Item Russia-Ukraine war and G7 debt markets: Evidence from public sentiment towards economic sanctions during the conflict(International Journal of Finance & Economics, 2023) Sulong, Z.; Abakah, E.J.A.; Adeabah, D.; et al.War-related expectations cause changes to investors' risks and returns preferences. In this study, we examine the implications of war and sanctions sentiment for the G7 countries' debt markets during the Russia-Ukraine war. We use behavioural indicators across social media, news media, and internet attention to reflect the public sentiment from January 1, 2022, to April 20, 2023. We apply the quantile-on-quantile regression (QQR) and rolling window wavelet correlation (RWWC) methods. The quantile-on-quantile regression results show a heterogeneous impact on fixed-income securities. Specifically, extreme public sentiment has a negative impact on G7 fixed income securities return. The wavelets correlation result shows dynamic correlation pattern among public sentiment and fixed income securities. There is a negative relationship between public sentiment and G7 fixed-income securities. The correlation is time-varying and highly eventful dependent. Our additional analysis using corporate bond data indicates the robustness of our findings. Furthermore, the contagion analysis shows public sentiment significantly influences G7 fixed income securities spillover. Our findings can be of great significance while framing strategies for asset allocation and portfolio performance and risk hedging.
