With the increase in local energy generation from Renewable Energy Sources (RESs), the concept of decentralized peer-to-peer Local Energy Market (LEM) is becoming popular. In this paper, a blockchain-based LEM is investigated, where consumers and prosumers in a small community trade energy without the need for a third party. In the proposed model, a Home Energy Management (HEM) system and demurrage mechanism are introduced, which allow both the prosumers and consumers to optimize their energy consumption and to minimize electricity costs. This method also allows end-users to shift their load to off-peak hours and to use cheap energy from the LEM. The proposed solution shows how energy consumption and electricity cost are optimized using HEM and demurrage mechanism. It also provides economic benefits at both the community and end-user levels and provides sufficient energy to the LEM. The simulation results show that electricity cost is reduced up to 44.73% and 28.55% when the schedul...

Risk is a great impediment confronting the performance of banks in Sub Saharan Africa. Liquidity and credit risk are the dominant form of risk affecting banking performance. This study seeks to examine the effect of liquidity risk and credit risk on the performance of banks in Sub Saharan Africa. The study used a sample of fifty (50) banks drawn across six Sub Saharan African countries that include Nigeria, Ghana, South Africa, Zambia, Kenya, and Tanzania. The two-step system generalized method of moment is the analysis tool used in the study. The findings from the study revealed that liquidity risk and credit risk are separately and jointly significant and negatively contribute to the performance of banks in Sub Saharan Africa. Banks management and practitioners are therefore encouraged to employ all the necessary measures to manage these risks under a single control as proposed in the Basel III regulatory provisions.

Bank size is one of the vital internal determinants of banking performance, although scholars hold contradictory views on bank size and its influence on performance. The aim is to examine the effect of bank size on quoted deposit money banks (DMBs) in the region of sub-Saharan Africa (SSA). The sample, collected over a period of nine years (2011-2019) included fifty listed commercial banks drawn from across the six sub-Saharan African countries, namely Nigeria, Ghana, South Africa, Zambia, Kenya, and Tanzania. The data were analyzed using a two-step system generalized method of moment (GMM). The finding revealed a significant and negative association between bank size and its financial performance. However, the smaller banks performed better when compared to their larger counterparts in the region. These findings seem to suggest that banks keep their capital level on the high side and minimize the rate of their non-performing loans in order to achieve more excellent banking perfor...

Purpose This study aims to examine the effect of liquidity risk on deposit money banks’ (DMBs) performance in Sub-Saharan Africa. This study also tests the interaction effect of liquidity risk and nonperforming loans on the performance of DMBs’ in Sub-Saharan Africa. Design/methodology/approach This study uses a two-step system generalized method of moment to test the influence of liquidity risk on DMBs’ performance in Sub-Saharan Africa. A sample of 50 listed banks across six Sub-Saharan African countries, including Nigeria, Ghana, South Africa, Zambia, Kenya and Tanzania, were used. The bank performance proxy used are return on asset and return on equity, while net interest margin is used for robustness check. Findings The study’s findings reveal a significant and negative association between liquidity risk and bank performance. Moreover, the relationship between the nonperforming loan and bank performance is negative and significant. Furthermore, the interaction effect of liquidi...

This study examine the effect of corporate governance practice and regulatory capital on the performance of deposit money banks in Nigeria. The study employed a panel data, covering 9 years period across 14 listed deposit money banks in Nigeria. An ordinary least square (OLS) regression was used to analyzed the data for the study. Breausch and Pagan LM and hausman test were conducted to ascertain the best model between pooled OLS, random effect and fixed effect. The study found that board size, non-executive directors and bank regulatory capital have a significant positive effect on the performance of deposit money banks in Nigeria, while role duality was insignificant. Based on the findings, the study recommend compliance to any good corporate governance practice and bank regulatory capital to maintain healthy banks.

Working capital is regarded as the lifeblood and nerve of a business concern, it is therefore essential to accommodate the smooth operations of any organization, but Studies in working capital management have provided inconclusive results. The objective of this study is to examine the effect of working capital management of Deposit Money Banks in Nigeria. The study covers the period of six years 2007 to 2013. Data for the study were extracted from the firms’ annual reports and accounts. After running the OLS regression, a robustness test was conducted for validity of statistical inferences, the data was empirically tested between the regressors and the regressed, A multiple regression was employed to test the model of the study using OLS. The results from the analysis revealed a strong positive relationship between current ratio and quick ratio and ROA of Listed Deposit Money Banks in Nigeria, while cash ratio was found to be inversely but significantly related to ROA of Listed Depo...

The success of an organization is contingent on a variety of factors, including technological, financial, and human resources. While all factors are critical, the most critical is the human resource, which combines all other factors into a goal-oriented action. Suliman et al. (2010) emphasize that personality traits are the most critical factor affecting human resource performance. Personality is characterized as persistent pragmatic, interpersonal, attitudinal, and emotional patterns that account for an individual's conduct in a variety of situations (McCrae and Costa, 1989). Over the last few decades, research into personality has accelerated in a variety of fields (Shi et al., 2021). The study of personality resulted in the establishment of personality psychology, a vibrant field of study in the social sciences for decades (Adamopoulos et al., 2018; Engel-Yeger et al., 2016). People are from different backgrounds and cultural heritages which influence their values, norms, attitudes and consequently a reflection of different personalities that highlight their actions and behaviour (Ghani et al., 2016) at the workplace.

Nonperforming loans posed a great threat to the performance of banks in emerging economies. This study seeks to examine the effect of nonperforming loans on the banks' performance in Sub-Saharan Africa region. A total of fifty (50) listed banks were drawn across six Sub-Saharan African countries that include Nigeria, Ghana, South Africa, Zambia, Kenya, and Tanzania within 9 years period (2010-2018). The study employs a two-step system generalized method of moment as the technique of analysis and inference. Findings from the study revealed a significant negative association between NPLs and bank performance within the region. Bank management and regulators are advised to work hard toward ensuring that banks keep minimum NPLs in order not to threaten the liquidity position of the banks.
