Item An Empirical Investigation of Capital Inflow and Dutch Disease: Evidence from Ethiopia(Addis Ababa University, 2018-06) Mohammed, Yimam; Alemayhu, Geda (Prof)This study investigates the Dutch disease impact of capital inflow using a quarterly time series data from 2000/01 1st quarter to 2016/17 fourth quarter. The study employed three separate re-gressions to examine the impact of capital inflow on spending, resource movement and established the impact of real effective exchange rate shock on net export. Regression analysis was carried out using auto regressive distributed lag (ARDL) approach to examine the impact of Capital inflow on real effective exchange rate and traded to non-traded sector ratio and then applied Bayesian Vector Auto-regressive to find the impact of real effective exchange rate changes on net exports of Ethiopia. The findings reveal that, foreign direct investment and foreign aid inflow does not have Dutch disease impact through spending effect both in the short run and the long run model. In resource movement effect, foreign direct investment inflow does not have any impact on resource reallocation from the tradable agricultural and manufacturing sector to non-tradable service sec-tor. But in the long run, foreign aid exerts a pressure on the movement of labor from the tradable to non-tradable sector ratio. The changes in real effective exchange rate have negative impact on net export in Ethiopia. While, real effective exchange rate respond positively to a unit shock in foreign direct investment and remittance inflow. Again, its response is also insignificant following a unit shock in foreign aid. Hence, there is lack of empirical support of Dutch disease in Ethiopia, suggests that Ethiopia has been able to effectively manage a surge capital inflows.Item Investigations on Some of The Engineering Properties of Soils Found in Kemise Town(Addis Ababa University, 2016-08) Mohammed, Yimam; Teferra, Alemayehu (Professor)The objective of this research is investigations on some of the engineering properties of soil found in Kemise town. Kemise is one of the reform towns which need many construction works in the future. To find the necessary information from the sub soil, geotechnical investigation on engineering properties of soil is very essential and it is one of the most important parts of Foundation engineering. However, the engineering properties of soils in the area are not studied. To achieve the central aim of this research nineteen disturbed and undisturbed soil samples were collected from eleven test pits. Thereafter, tests for engineering properties were carried out in the laboratory. According to engineering properties test results, it is concluded that the type of soils found in Kemise town is clay, silt and silty sand. Based on the type of soils identified the clay soils have liquid limit ranging from 40 to 84.9%, plastic index ranging from 16.7 to 55.4%. Silt soils have liquid limit ranging from 36.8 to 67.5%, plastic index ranging from 12.1 to 34.7%. While silty sand soil has liquid limit ranging from 30.7 to 37.4%, plastic index ranging from 6.5 to 10%. The consistency of soils which are stiff to hard, identified based on the liquidity index value. The results obtained from consolidation test, the values of coefficient of consolidation and Coefficient of permeability are reduced with effective stress increment. The coefficient of permeability ( to cm/sec) indicating that the soil sample investigated in study area is practically impermeable (impervious soil).Item Time Series Analysis on the Outgoing International Telephone Calls to Saudi Arabia (1989 G.C. - 1996 G.C.)(Addis Ababa University, 1999-06) Mohammed, Yimam; Omer, Mohammed (PhD)
