    Financial Development and Economic Growth Revisited: Evidence from the Case of Selected Sub-Sahara African Countries
    (Addis Ababa University, 2016-06) Getachew Yohannes; T. Adane
    The finance – growth nexus, though it is well-entrenched in the academic discourse and no consensus is reached, still begs for updating through revisiting the issue using recent data. With this motivation, this paper has attempted to achieve two paramount objectives: examining the effect of economic growth on the development of the financial system and investigating the effect of other variables which were presumed and simultaneously supported by substantial body of literature to have significant effect on economic growth; a case from 20 selected sub-Sahara African region. Pertaining to this, first using annual data of 20 selected sub-Sahara African countries were collected and transformed in to five years averaged longitudinal data form, we applied multilevel mixed effects regressions (MMER). The results from the mixed effect regression revealed that, there is a significant and positive effect of economic growth, geographic location allotting sea door, macroeconomic stability, investment and domestic savings. On the contrary, negative relationship was observed between foreign legal system origination and financial development. The evidence under the probe on the effect of demographic situations have two effects comprising both direct relationship with financial depth and indirect effects on the efficiency of the financial system. Finally this paper has ended up suggesting further detailed research on the effects of demographic situations on financial development; additionally to examine the finance growth nexus and give microeconomic evidence. Key words: financial depth, efficiency of financial system, economic growth, multilevel mixed effect regression, microeconomic evidence.

    Seroprevalence of Brucellosis in Small Ruminants and Humans in Amigna District Selected Peasant Association, Arsi Zone, Oromia Regional State, Ethiopia
    (Addis Ababa University, 2011-06-01) Getachew Yohannes; Tesfaye Sisay
    A cross sectional study was undertaken in selected five peasant associations found in South East Ethiopia. Amigna district, Arssi Zone, from October 2010 to March 2011 to determine the seroprevalence of Brucellosis in small ruminants and human risk groups (farmers). Sera samples were collected from 100 households and 700 small ruminants (350 goats, 350 sheep). The sampling include small ruminants above 6 month of age and human risk group who had close contact with small ruminants, visited the district's Health Center and had suspected on brucellosis. The sera samples were screened using modified Rose Bengal test (MBRPT), and there was no detection of anti brucella antibodies in 700 animal and 100 human blood samples. During the questionnaire survey, it was found that 28% replace the stock with own stock, 22% from village stock, 50% from both stock. Among the total households 73 owners (73%) used unsafe methods to disposal fetal membrane, whereas 27 (27%) applied safe disposal of fetal membrane. Although antibodies were not detected in sera of animals and humans in the area, there is a human practice favorable for the transmission of the disease from animals to humans. In line with these results, there should be strict regulation in preventing introduction of brucellosis to the area; and humans should avoid practicing risky activities so that transmission of the disease to humans will be prevented
