This study analyzes the effects of technological progress for energy intensity and energy use related carbon dioxide emissions during urbanization in China by a dynamic computable general equilibrium model. The parameters about technological progress and urbanization are all exogenously given. The impacts of technological progress on economic growth, energy intensity and carbon dioxide emissions during period from 2002 to 2030 are examined. Simulation results show that gradually pushing energy efficiency related technologies through appropriate policy incentives is the key to realize low-carbonized development while promoting economic growth in China.

Purpose The purpose of this study is to investigate the impacts of urbanization on per capita energy consumption and emissions in India. Design/methodology/approach The present study analyses the effects of urbanization on energy consumption patterns by using the Stochastic Impacts by Regression on Population, Affluence and Technology in India. Time series data from the period of 1960 to 2015 has been considered for the analysis. Variables including Population, GDP per capita, Energy intensity, share of industry in GDP, share of Services in GDP, total energy use and urbanization from World Bank data sources have been used for investigating the relationship between urbanization, affluence and energy use. Findings Energy demand is positively related to affluence (economic growth). Further the results of the analysis also suggest that, as urbanization, GDP and population are bound to increase in the future, consequently resulting in increased carbon dioxide emissions caused by increased energy demand and consumption. Thus, reducing the energy intensity is key to energy security and lower carbon dioxide emissions for India. Research limitations/implications The study will have important policy implications for India’s energy sector transition toward non- conventional, clean energy sources in the wake of growing share of its population residing in urban spaces. Originality/value There are limited number of studies considering the impacts of population density on per capita energy use. So this study also contributes methodologically by establishing per capita energy use as a function of population density and technology (i.e. growth rates of industrial and service sector).

<p>Changes in exchange rate and international prices greatly affect food availability, the agricultural sector, and Gross Domestic Product (GDP). This study quantifies the effects of change in exchange rate and world prices on Sudan’s agricultural production, imports, exports, and GDP. Special emphasis has been placed on sorghum and wheat, the main food grains. A Standard Computable General Equilibrium model has been developed and used for the analysis. The main objective is to contribute to policy-making process for enhancing food security and social welfare in the Sudan<strong>.</strong></p> <p>Currency depreciation would reduce wheat imports and increase its domestic production, increase sorghum export, increase domestic output and export of sesame and cotton, and improves GDP; and vice versa for appreciation. Appreciation favors urban (wheat) consumers, whereas depreciation favors rural (sorghum) consumers.</p> <p>Increasing world price of wheat would decrease its imports, whereas that of sorghum would encourage its production and export, and increase domestic food prices. GDP decreases due to investment reduction<strong>. </strong></p> <p>It is recommended that wheat import should be conditioned on hard currency availability and food gap, while maintaining stable exchange rate that strike a balance between encouraging sorghum exports and wheat imports. It is also recommended to encourage innovation of fast food from traditional grains to curb the shift to wheat consumption.</p>

Diverse factors may have an impact in carbon dioxide (CO2) emissions; thus, three main contributors, energy consumption, gross domestic product (GDP) and an exergy indicator are examined in this work. This study explores the relationship between economic growth and energy consumption by means of the hypothesis postulated for the Environmental Kuznets Curve (EKC). Panel data for ten countries, from 1971 to 2014 have been studied. Despite a wide gamma of research on the EKC, the role of an exergy variable has not been tested to find the EKC; for this reason, exergy analysis is proposed. Exergy analyses were performed to propose an exergetic indicator as a control variable and a comparative empirical study is developed to study a multivariable framework with the aim to detect correlations between them. High correlation between CO2, GDP, energy consumption, energy intensity and trade openness are observed, on the other hand not statistically significant values for trade openness and energy intensity. The results do not support the EKC hypothesis, however exergy intensity opens the door for future research once it proves to be a useful control variable. Exergy provides opportunities to analyze and implement energy and environmental policies in these countries, with the possibility to link exergy efficiencies and the use of renewables.

The linkage between trade liberalization, environmental quality and economic growth is becoming an increasingly popular issue in environmental economics in recent decades. In view of Pakistan’s position as one of the main contributors to carbon dioxide emissions in Asia, it is vital to identify the main determinants of carbon dioxide emissions. The present study empirically investigates the long run association among trade liberalization, environmental quality and economic growth along with other variables energy use and capital labor ratio in Pakistan for the period 1980-2018. The results also indicate that there is inverted U shape relationship between economic growth and carbon dioxide emissions, hence the environmental Kuznets curve hypothesis is valid in Pakistan during 1980-2018. Trade openness has a negative significant impact on carbon dioxide emissions. Capital labor ratio effects and energy use have a direct relationship with carbon dioxide emissions. The results show that environmental quality is first declined by economic growth but with further increase in growth, environmental quality is improved which supports the existence of Environmental Kuznet curve hypothesis in Pakistan during that time span.          Furthermore, results also show that trade openness has positive significant impact on environmental quality.

Abstract This study employs a partial general equilibrium approach calibrated on the Social Accounting Matrix (SAM) and a contemporaneous dynamic computable general equilibrium (CGE) model to assess the effect of expansionary fiscal policy on economic growth, income inequality, poverty, employment and inequality reduction in South Africa. The simulation results reveal that expansionary fiscal policy i) benefits rich ‘white’ households the most and poor ‘coloured’ households the least ii) improves adult employment more than youth employment iii) improves employment in urban areas as proposed to employment in rural areas iv) has a very small effect on improving economic growth and reducing the Gini coefficient v) benefits ‘well-off’ households more than it does ‘poor’ households vi) promotes ‘low-skilled’ employment more than it does for ‘high-skilled’ labourers. Associated policy implications based on our findings are also discussed.

Abstract In response to rapidly growing energy demands, Chinese authorities plan to invest more in hydropower development. However, there are concerns about the possible effects on macroeconomy. This paper uses SinoTERM, a dynamic multi-regional computable general equilibrium model (CGE) of the Chinese economy, to analyze the economic impact of large hydropower development projects. The model features regional labor market dynamics and an electricity subdivision module with substitutability between various types of electricity generation. The results suggest that hydropower development will boost economic growth in the project region. Most sectors in the project region will benefit from the hydropower development such as other services, health, and education, while some sectors will suffer a loss in output because of the substantial increase in real wages. For the national, every 10,000 yuan investment can drive the national GDP growth of 1,000 yuan, and the cost is expected to be recovered in ten years. By the end of 2040, the real national wage will be around 0.16% higher than the baseline scenario. The project could only be justified if net environmental benefits outweigh this loss.
