China’s iron and steel sector is the largest in the world and has been the backbone of Chinese heavy industry. This sector is also a major consumer of energy and, in particular, coal. As a result, the iron and steel sector in China is a major contributor to greenhouse gas emissions and...

Studies in the economics of crime literature have reached mixed conclusions on the deterrence hypothesis. One explanation that has been offered for the failure to find evidence of a deterrent effect in the long run is the natural rate of crime. This article applies univariate unit root tests to...

This article examines the long-run and short-run determinants of migration from Fiji to the United States between 1972 and 2001 using a human capital framework, which is extended to take account of political instability in Fiji. In the long-run the authors find that differences in income levels,...

This paper applies univariate and panel data unit root tests to annual panel data for 182 countries over the period 1979-2000 to examine the stationarity properties of per capita energy consumption. The univariate unit root test can only reject the unit root null for 29 per cent of the countries...

This paper tests Wagner's law of increasing state activity using panels of Chinese provinces. The paper's main methodological contribution is in that we employ for the first time in the literature on Wagner's law a panel unit root, panel cointegration and Granger Causality testing approach....

This paper examines the impact of military expenditure and income on external debt for a panel of six Middle Eastern countries; namely, Oman, Syria, Yemen, Bahrain, Iran, and Jordan, over the period 1988 to 2002. Using Pedroni's (2004) test for panel cointegration, we find that there is a...

Studies in the economics of crime literature have reached mixed conclusions on the deterrence hypothesis. One explanation which has been offered for the failure to find evidence of a deterrent effect in the long run is the natural rate of crime. This paper applies the univariate Lagrange...

This paper examines the unit root properties of crude oil production for 60 countries employing a range of panel data unit root tests for the period 1971 to 2003. The study first employs a number of panel data tests that do not accommodate structural breaks and then proceeds to apply the...
