Abstract: This study examines the dynamic relationship between oil revenue, government spending and economic growth in Nigeria. Since the discovery of oil, oil proceeds have dominated the country's federation account and have improved public spending. In this paper, we analyse if the huge government spending has improved the rate of economic growth. To do this, the multivariate vector autoregression framework with special attention to Generalised Impulse Response Function is adopted in analysing the annual data of oil revenue, total government expenditure and real Gross Domestic Product from 1980 to 2015. We find evidence that oil receipts remain the major route which public spending is financed and the fundamental source for growth. Hence, there is need for the government to diversify the sources of foreign exchange inflow of the country. The diversification of the economy is required to insulate it from external shocks. It is recommended for Nigeria to explore ways of reviving its huge agricultural potential which has been neglected since the discovery of oil in addition to exploring its rich untapped solid minerals deposit in order to promote diversification of the economy away from a mono cultural product base.

Boulding's 1966 paper on the economics of spaceship Earth established the framework for ecological economics and an understanding of economic growth. In ecological economics, economies are conceptualized as open subsystems of the closed biosphere and are subject to biophysical laws and constraints. Economic growth measured as an increase in real gross domestic product (GDP) has generally been associated with increases in the use of energy and materials and the generation of wastes. Scale, composition, and technology are the proximate determinants of environmental impacts. They are often reduced to two: scale (GDP) and intensity (impact per unit GDP). New work described in this paper defines “green” growth as intensity that declines faster than scale increases. Similarly, “brown” growth occurs when intensity declines more slowly than increases in scale, and “black” growth happens when both scale and intensity increase. These concepts are then related to the environmental Kuznets curve, which can be understood as a transition from brown to green growth. Ecological economics provides a macroperspective on economic growth. It offers broad policy principles, and it challenges the primacy of economic growth as a policy objective, but many important questions remain. [ABSTRACT FROM AUTHOR]

This paper reviews the mainstream, resource economics, and ecological economics models of growth. A possible synthesis of energy-based and mainstream models is presented. This shows that when energy is scarce it imposes a strong constraint on the growth of the economy; however, when energy is abundant, its effect on economic growth is much reduced. The industrial revolution released the constraints on economic growth by the development of new methods of using coal and the discovery of new fossil fuel resources. Time-series analysis shows that energy and GDP cointegrate, and energy use Granger causes GDP when capital and other production inputs are included in the vector autoregression model. However, various mechanisms can weaken the links between energy and growth. Energy used per unit of economic output has declined in developed and some developing countries, owing to both technological change and a shift from poorer quality fuels, such as coal, to the use of higher quality fuels, especially electricity. Substitution of other inputs for energy and sectoral shifts in economic activity play smaller roles. [ABSTRACT FROM AUTHOR]

One of the strong factors reflecting Africa's economic backwardness is the low level of industrial development. Not only does the industrialization process appear to have bypassed the continent, there is evidence of de-industrialization in the case of several countries. This paper seeks to address a set of interrelated questions: To what extent is the growth performance of African economies related to these structural characteristics? More precisely, is there any discernible evidence that GDP growth and overall labour productivity growth of African countries is positively related to how fast their industrial sector is growing? We test out Kaldor's three growth laws: first, that the growth of GDP is positively related to the growth of manufacturing output not simply in a definitional sense (because manufacturing output is a part of GDP) but in a fundamental causal sense related to the production characteristics of manufacturing activity; secondly, that the growth of labour productivity in manufacturing is positively related to manufacturing output growth because of static and dynamic increasing returns to scale (Verdoorn's Law); and thirdly, that there will be a negative relation between labour productivity growth in the economy as a whole and the rate of growth of employment in the non-manufacturing sector because most activity outside the manufacturing sector is subject to diminishing returns, particularly in land-based activities such as agriculture and many service activities. The authors' conclusions are that there is some empirical support for Kaldor's growth laws in respect of the countries of Africa. The growth of GDP seems much more closely associated with the growth of the manufacturing/industrial sector than the agricultural or service sectors. Structural change in favour of industrial activities would almost certainly help to accelerate the growth of GDP and living standards in Africa. [ABSTRACT FROM AUTHOR]
