    Determinants of Commercial Banks’ Lending: The Case of Selected Private Commercial Banks in Ethiopia
    (A.A.U., 2020-03) Yared, Bekele; Habtamu, Birhanu
    The study was aimed to investigate the determinants of commercial banks’ lending on the selected private commercial banks in Ethiopia based on Bank specific, regulatory and macro-economic factors of the country. In order to achieve research objective the researcher used quantitative research approach. The analyses were performed using panel data derived from the financial statements of sampled Ethiopian commercial banks and macro-economic data from National bank of Ethiopia. Ordinary least square (OLS) technique was applied to determine the impact of those predictor variables on commercial bank lending. In the study volume of deposit, cash reserve requirement, legal reserve requirement, non-performing loan, liquidity ratio, capital adequacy ratio, equity investment, and GDP of the country were considered as independent variables whereas commercial banks’ lending or loan and advances was considered as dependent variable. The result of the regression analysis reveals that Ethiopian commercial banks’ lending is determined by volume of deposit, non-performing loans, legal reserve requirement and GDP growth, positively. On the other hand capital adequacy, legal reserve requirement, equity investment and liquidity have insignificant impact on Ethiopian commercial banks’ lending or loan and advances. The study suggests that Ethiopian commercial banks should enhance their strategies in mobilizing deposits from the public and have to strive to strength their asset quality. In addition commercial banks’ should administer their lending activity by considering internal factors, existing economic situation, competitive environment, regulatory measures and their target customers.

    Factors Affecting Knowledge Sharing for Entrepreneurial Development: the case of Micro and Small Enterprises Engaged in Manufacturing in Addis Ababa
    (A.A.U, 2016-10) Yared, Bekele; Elizabeth, Ayalew(Dr.)
    The purpose of this research is assessing the enabling factors of knowledge sharing for entrepreneurs engaged in micro and small enterprise manufacturing by considering technology, individual, organization, extrinsic and intrinsic knowledge sharing factors. Lack of management insight into the ground and any historical data one can fall back on is a reality every entrepreneur has to face. Knowledge on legal procedures, competition, time and finance management, location and timing, etc. is all critical considerations that will decide the success or failure of any startup. The thesis attempts to identify knowledge sharing factors that hinder aspiring entrepreneurs from benefiting the knowledge acquired by their predecessors and relevant governmental and non-governmental actors in order to establish and operate successful ventures. The research approach applied in this study was a quantitative and qualitative method to collect data. From the finding and exhaustive literature review, a knowledge sharing model was developed, which consist of five knowledge sharing factors: technological, individual, organizational, extrinsic and intrinsic. The result of the study indicated that technology, individual, organization and intrinsic factors were the most critical one for knowledge sharing among entrepreneurs engaged in the manufacturing sector. Finally, the researcher recommended that the solutions to MSE to tackle the problem all potential entrepreneurs face regarding knowledge sharing.

    Study on Impacts of Distributed Generation Integration in Medium Voltage Radial Distribution system (Case Study: Sebeta-I Substation)
    (AAU, 2018-10) Yared, Bekele; Getachew, Bekele (PhD)
    The mission of every electric company is to transmit, distribute and supply electricity in reliable and efficient manner. However in comparison to the part of the power system supplying energy (the large generating units and the transmission grid), the distribution system, feeding load, is very extensive and has high R/X ratio causing more power loss, poor voltage stability and large voltage drop in the network which results with voltage magnitude at the customer terminal out of permissible limit. On the other hand, increasing power demands has led to the existing aging power system operation becoming more challenging from the points of security, reliability, efficiency and quality of the electric power supply. To catch up with and possibly overtake these issues, integration of distributed generation into the distribution system is one possible solution. Integrating distributed generation into the system at a proper place with a proper size makes the grid capable to distribute and supply electricity in reliable and efficient manner with improvement of several technical parameters. The purpose of this study is to investigate the impact of distributed generation integration on a radial distribution system. The feeder SEB-12 of Sebeta-I Substation of medium voltage radial distribution system which having 44 buses is taken as a case study area to determine the impact of distributed generation integration on a radial distribution network. The feeder was selected due to its highest power interruption frequency and long duration power outage during the two year recorded data. The impacts of DG integration on total power loss, voltage profile, voltage stability, loading of line segment, fault level, and protection coordination of the distribution system were investigated. Modelling of the case study distribution network is simulated using DIgSILENT PowerFactory 15.1.7 simulation package. The results of base case balanced and positive sequence load flow analysis at steady state condition indicated that the feeder has total power loss of 1.91 MW and 2.07 MVAR with the terminal voltage magnitude at the majority of the buses being out of acceptable limit. The minimum node voltage magnitude of 0.832 p.u. (12.479 kV) is found at bus 18 which is far out of allowable voltage range of 1±5%. To reduce the total power loss of the network, and improve voltage profile of the system to within allowable range, distributed generator is integrated to the network at a proper place with a proper size. In this thesis sizing and sitting of DG was performed based on analytical method and load flow analysis respectively. The proper size of DG was found to be 12.098MW with the proper place at bus 14. The results of simulation after the integration of DG revealed that the total real and reactive power loss is reduced to 0.30 MW and 0.28 MVAR with the total loss reduction of 84.29% and 86.47% respectively, while all node voltages had improved to within permissible limit of 1±5%. In general, the impact of DG integration on total power loss, voltage profile, loading of line segment and voltage stability of the system are positive while there are some negative impacts such as increase in fault level and miss-coordination of protection devices.
