    ENERGY EFFICIENCY AND ECONOMIC GROWTH IN ETHIOPIA TIME SERIES ANALYSIS
    (WOLKITE UNIVERSITY, 2020-08) DESALEGN DEBEBE SORATO
    We have limited studies on the relationship between energy efficiency and economic growth in the context of sub Saharan Africa where efficient energy supply is limited although energy is vital to meet sustainable development goals. Considering this, this study investigates the long run relationship between energy efficiency and the economic growth in Ethiopia for the period 1974/75 to 2017/18. Multivariate time series analysis was employed. The result indicated that the existence of unidirectional causality running from economic growth to energy efficiency. Similarly, for the sectoral share of GDP, the unidirectional causality runs from energy efficiency to industry share while as bidirectional causality runs from service shares to energy efficiency and vice versa. The speed of adjustment coefficient indicates that the previous period disequilibrium adjusts to equilibrium at the rate of 59.2% annually. Impulse response function specifies responsiveness of the energy efficiency in the model to the shocks in the error term indicated that economic growth has significant influence while variance decomposition measured the strength of causality relationship showed high causal effect to energy efficiency. The overall result showed that increased economic growth has a strong cause of energy efficiency in Ethiopia. The government needs to give more importance to sustain economic growth so that both the wellbeing and the energy efficiency of the nation are improved.

    FINANCIAL DEVELOPMENT SECTOR AND ECONOMIC GROWTH IN ETHIOPIA

With this motivation, this study has attempted to achieve the objective: examining the financial sector development and economic growth in Ethiopia and their causality based on the time series data set covering the period of 1974/75 to 2019/20 in Ethiopia, using Eview9 software. From a methodological perspective, unit root tests, Johansson’s co integration test, vector error-correction model, impulse response analysis, variance decomposition analysis and granger causality tests were utilized. The finding of this study shows that financial development sector, gross capital formation /investment/, saving and government expenditure have a positive and statistically significant relationship with GDP in the long run. In the short run, the study confirms that one year lagged value of financial development and savings are positive and statistically significant affecting current growth of RGDP. The study also found that there is no causality running from either financial development sector to economic growth or from economic growth to financial development both in the long run and short run. The short run speed of adjustment coefficient of -0.247 indicates that 24.7 % of the short run adjustment made within a year. Finally, the study recommends the policy towards the path of a sustainable growth and the effects of financial sector on economic growth must be taken into consideration.rough revisiting the issue using recent data.
