This paper tests for convergence in relative per capita electric power consumption for 22 African countries, covering the period 1971-2002. Parametric techniques which are regressions and unit root tests are used. Neoclassical convergence hypothesis such as the ?-convergence is rejected while...

The paper tests the material Kuznets Curve (MKC) hypothesis with regard to aluminium consumption for 20 high-income countries over the period 1970 to 2009. The test is based on the suggestion of Narayan and Narayan (2010). Various unit root and cointegration tests are applied. The aluminium and...

The paper examines the copper consumption-economic growth nexus for 16 rich economies from the period 1966 to 2010. Various generations of panel unit root and cointegration tests are applied. Both series are found to be integrated of order one. Evidence of cointegration is found especially when...

This paper investigates how various socio-demographic as well as psychological factors are related to the purchasing frequency of Le Millionaire scratch card in Mauritius. In order to obtain a refined description and understanding of consumer behaviour, special attempts have been made to control...

The aim of this paper is to analyze the importance of human capital on productivity growth for 26 African countries over the period 1976-1996. To estimate productivity change, the Malmquist total factor productivity (TFP) growth index is computed. This index is then decomposed into technical...

The paper attempts to test the Environment Kuznets Curve (EKC) hypothesis for 36 high-income countries for the period 1980-2005. The test is based on the suggestion of Narayan and Narayan (2010). Various panel data unit root and co-integration tests are applied. Carbon dioxide (CO2) emissions...

This paper investigates the convergence pattern of technical efficiency of the South Africa Power Pool (SAPP) utilities over the period April 2003–March 2010 by means of parametric and non-parametric techniques. Technical efficiency scores are computed via both stochastic frontier analysis and...
