Effects of Corporate Governance on the Financial Performance of Commercial Banks in Ethiopia
(Addis Ababa University, 2026-06-02) Temesgengen Teshale; Sisay Regassa
This paper would research on the impacts of corporate governance on the financial performance of commercial banks in Ethiopia. The paper analyses one hundred and ten bank-years of panel data of ten commercial banks during the time 2014-2024. There are six governance variables, including board size, board independence, CEO duality, audit effectiveness, frequency of board meetings, and ownership concentration. ROA and ROE are used to measure financial performance. The research design used is explanatory research design based on a quantitative approach. In the case of Hausman test, fixed effects regression is employed. Diagnosis checks show that there is no heteroskedasticity and autocorrelation, but multicollinearity is observed between the independence of the board and audit performance. Both Return on Assets and Return on Equity have negative and statistically significant correlation with the board size, which have an adverse impact on the financial performance of large boards. CEO duality is observed to positively and significantly influence both the performance measures hence indicating that unified leadership is effective in promoting performance within the Ethiopian context. Concentration of ownership has adverse impact on Return on Assets as well as Return on Equity. Returns on Assets are not impacted by audit effectiveness in a negative way. No significant effects are found in board independence and the frequency of meeting. The models account about seventy one percent of within bank variation in performance. These results undermine traditional wisdom of governance and create an indication that Ethiopian banks require context-specific governance structures. The research suggests that the NBE should issue purer procedures on optimum board size, indorsing an adequate range that heightens efficiency and decision-making. Management should evaluate leadership structure based on ownership bank size, and operational complexity instead of implementing uniform corporate governance practices. Investors should pay close attention to ownership structure and board size when making investment decisions, as higher board size and high ownership concentration are negatively affect financial performance.
The Effect of Global Supply Chain Changes on Ethiopian Coffee Export Performance: The Mediating Role of Government Support Among Seleced Coffee Export Firms in Addis Ababa
(Addis Ababa University, 2026-06-01) Tsehay Girma; Dejene Tulu
The purpose of this study was to use government support as a mediator to examine the effect of changes in the global supply chain on Ethiopian coffee export performance. An explanatory research design was used in this investigation. A survey questionnaire was used to gather the necessary data, which came from both primary and secondary sources. A sample of 384 respondents was initially determined using Yamane’s (1967) formula. However, 156 valid questionnaires were successfully collected and analyzed, representing a response rate of 40.6%. the collected data were considered adequate for multiple regression and mediation analysis. The link between the independent variable (Global Supply Chain Changes) and the dependent variable (Coffee Export Performance) was assessed using correlation and regression analysis. Whereas, Andrew Hayes PROCESS Model 4 was employed to analyze the mediating role of Government Support between the relationship of Global Supply Chain Changes and Coffee Export Performance. The regression result showed that Government Support had a positive and significant effect on Coffee Export Performance (β = 0.7453, p < 0.001), explaining 67.9% of the variance in Coffee Export Performance (R Square = 0.679, Adjusted R Square = 0.675). The researcher discovered that there was a positive and significant impact of global supply chain changes on coffee export performance (β = 0.2138, p < 0.001) when the mediating variable of government support was disregarded. The indirect effect of government support was found to be positive and significant (Effect = 0.0597, BootSE = 0.0284, 95% BootCI: 0.0017 to 0.1141), with the bootstrap confidence interval not containing zero, suggesting that about 21.8% of the total effect is transmitted through the mediator. This suggests that government support plays a partial mediating role in the relationship between global supply chain changes and coffee export performance. The study suggests that policymakers and government agencies prioritize strengthening government support mechanisms, particularly market intelligence and training programs for coffee exporters, as well as investing in climate-resilient infrastructure and stable regulatory frameworks, because government support acts as a critical mediator, enhancing the positive relationship between global supply chain adaptations and Ethiopia's coffee export performance.

This study measured the emotional intelligence of principals and their leadership effectiveness using the Emotional Intelligence Appraisal and Leadership Improvement Tool. A descriptive correlation research design was used to achieve the objectives of the study. The research participants were 68 principals and 123 teachers who work in private Pre-schools in Yeka Sub City. For the purpose of this study two kinds of standardized questionnaires were used: to measure the emotional intelligence of the pre-school principals the researcher used The Emotional Intelligence Self Appraisal and to measure their leadership skill an Educational Improvement Tool was used. The data analysis has been done using different statistical techniques like frequency counts, mean, standard deviation and IBM SPSS version 20, Peat•sons product moment correlation test were used to investigate the relationship between the dependent and independent variables. At-test was employed to determine if there was a significant difference between the mean scores of the school principals and teachers. The result of this study revealed that the existing level of emotional intelligence of pre-school principals has a significant effect on their leadership performance. In addition there was a difference score between pre-school principals and teachers rating. When age and years of experience compared to emotional intelligence it does not have a significant effect on leadership performance. Thus Implementation of EI in any organization by a leader to be effective and efficient plays a vital role to leadership skill. Therefore pre-school principals need to work on their emotional intelligence considering the effect that their EI skill has an impact on their educational leadership skill and successes in their working environment.
