Still, over 2 billion people rely on traditional biomass for their daily energy needs. To overcome the negative effects of traditional energy on human health and the environment and to enhance the livelihood conditions of the poor, a transition towards cleaner and more efficient forms of energy is needed. Understanding household fuel choice and fuel switching behaviour is of vital importance in search for policies to support such a transition process. We use primary data set to investigate the determinants of household fuel choice and energy transition in Degehabur and Kebridahar towns. We observe that energy transition did not occur the two towns. Regression results from an ordered probit model show that households’ economic status, price of alternative energy sources, and education are important determinants of fuel choice in urban Ethiopia. The results also suggest the use of multiple fuels, or “fuel stacking behavior.” We argue that policy makers could target these variables to encourage transition to cleaner energy sources.

This study comprehensively analyzes the drivers of enterprise innovation in developing countries. The study uses survey data to analyze the determinants of enterprise innovation in Ethiopia using a multivariate probit (MVP) model. For this study, enterprises were grouped into four categories: all-sized, large-sized, medium-sized, and micro-and small-sized enterprises. It appears that engagement in R & D, on-the-job training, and website ownership significantly determine enterprise innovation. This study, unlike previous studies, comprehensively analyzes drivers of innovation by considering enterprises in different sizes and all at the same time. This helps identify factors most relevant for enterprise innovation at all stage which help policymakers get focused on strategy development. Based on the findings, further emphasis on engagement in R & D would help enterprises to become innovative for all categories of enterprises. Furthermore, strengthening the available formal training and diversifying type of the training that is related to skills, knowledge, and techniques that help achieve the long-term objective of the enterprises are worth considering. Enterprises also need to subscribe to different sites that help learn more and access information.

However, when not used efficiently, its negative consequences on any economy is enormous. This could be related to threatening the sustainable development of the economy, energy security and worsening the environmental conditions (Adom and Kwakwa 2014). Challenges like climate change and energy security that world economy is facing the in the twenty first century is mainly due to energy consumption. Since anthropogenic emissions of carbon dioxide (CO 2) result predominantly from the combustion of fossil fuels, energy consumption is at the focus of the climate change debate. According to U.S Energy Information and Administration (EIA) (2016), world energy-related CO 2 emissions increase from 32.3 billion metric tons in 2012 to 35.6 billion metric tons in 2020 and to 43.2 billion metric tons in 2040. Efficient energy utilization has a great role in an economy. Promoting energy efficiency has several potential benefits which consist of promoting market

Results from the PP unit root test shows that all variables under consideration are I(1). Result from the ARDL Bounds Testing indicates that there exists co-integration among gross domestic savings, gross domestic investment, real gross domestic product, labor force and human capital when RGDP is taken as dependent variable. Labor and investment have significant positive effect on economic growth of Ethiopia both in the short-run and long-run while GDS and human capital are statistically insignificant. Moreover, Toda-Yamamoto and Dolado-Lutkepohl as well as Innovative Accounting Techniques (i.e., IRFs and FEVD) approach to Granger causality analysis shows that there exists bidirectional causality between gross domestic investment and economic growth as well as between gross domestic savings and gross domestic investment. Granger causality running from investment to savings and from investment to growth is stronger as witnessed from impulse responses and variance decompositions. Although there is unidirectional Granger causality running from economic growth to gross domestic savings, it is weak. To attain high and sustained growth in the country, increased savings and especially investment are required due to its dual effect.

This study analyzes the nexus among energy consumption, affluence, financial development, trade openness, urbanization, population and CO2 emissions in Ethiopia using data from 1970–2014. The ARDL cointegration results show that cointegration exists among the variables. Energy consumption, population, trade openness and economic growth have positive impact on CO2 in the long-run while economic growth squared reduces CO2 emissions which confirms that the EKC hypothesis holds in Ethiopia. In the short-run urbanization and energy consumption intensify environmental degradation. Toda-Yamamoto granger causality results indicate the bi-directional causality between energy consumption and CO2 emissions, CO2 emissions and urbanization. Financial development, population and urbanization cause econom...

climate-resilient growth goals. Understanding the factors that determine energy intensity plays a crucial role for academics and policymakers to formulate sound energy
conservation and energy efficiency policies. This article investigates drivers of energy
intensity in Ethiopia over the period of 1974–2014. The ARDL bounds test approach
to cointegration and FMOLS-based Hansen parameter instability test methods were
applied to examine the long-run relationship among the variables. The result reveals
that there is an inverted U-shape or Environmental Kuznets curve-type relationship
between economic growth and energy intensity, implying that economic growth at
early (industrialization) stage of development spurs energy intensity while delinking
occurs at the later stages of development. Urbanization increases energy intensity,
while impact of import is negative. The Toda–Yamamoto Granger causality test result
shows a bidirectional causal relationship between import and energy intensity. Moreover, energy intensity Granger causes aid and industrialization.

This study analyzes the nexus among energy consumption, affluence, financial development, trade openness, urbanization, population and CO2 emissions in Ethiopia using data from 1970–2014. The ARDL cointegration results show that cointegration exists among the variables. Energy consumption, population, trade openness and economic growth have positive impact on CO2 in the long-run while economic growth squared reduces CO2 emissions which confirms that the EKC hypothesis holds in Ethiopia. In the short-run urbanization and energy consumption intensify environmental degradation. Toda-Yamamoto granger causality results indicate the bi-directional causality between energy consumption and CO2 emissions, CO2 emissions and urbanization. Financial development, population and urbanization cause economic growth while economic growth causes CO2 emissions. Causality runs from energy consumption to financial development, urbanization and population which in turn cause economic growth. From the result, CO2 emissions extenuation policy in Ethiopia should focus on environmentally friendly growth, enhancing consumption of cleaner energy, incorporating the impact of population, urbanization, trade and financial development.

Understanding this fact, the government and NGOs are currently carrying out several activities to improve the coverage and quality of water supply. To this end, willingness to pay of households that are expected to be benefited from the project should be analysed. The central objective of this study is, hence, to estimate Willingness to Pay (WTP) of households for better-quality water service provision and identify its determinants by using Contingent Valuation Method (CVM) in Jigjiga city. We estimate Willingness to Pay (WTP) for better quality of water supply service on cross-sectional survey of households in Jigjiga city taking 210 sample households randomly drawn. The highest relative WTP for improved water supply service was found in the city with the highest percentage of respondents being unsatisfied with the current water supply both in terms of quality and quantity. Response to the hypothetical scenario shown that sampled households stated that their mean WTP of 94 cents per 20 litres. The results of logit model

The results of logit model revealed that household income, family size, water source, age of the respondent and
bid value have significant effects on WTP for improved water service provision. The
implication is that it is better take into account the socio-economic characteristics of
the households in planning and designing water supply projects, which may serve to
set rigorous demand oriented projects that can sustain the service delivery.
