Taking a European cross-country perspective, this paper addresses the most important issues in the nexus of population ageing and labor markets. We start from a descriptive overview of the demographic change currently shaping European societies. The subsequent section intensively discusses the...

CO2 emission rates from commercial and residential sectors, as well as transportation, are high. Applications of solar energy as a fuel-switching measure and of fuel cells for energy-efficiency improvement can reduce CO2 emissions from these sectors. Photovoltaic (PV) energy systems using...

Energy conservation (EC) has been taken as basic state policy in China for more than 20 years and China achieves 3.9% annual energy saving from 1980 to 2005. In 2006 China Central Government firstly set up a binding target of reducing GDP energy intensity by 20% in its 11th Five-Year-Plan (FYP)....

Water hyacinth, as waste biomass, can potentially replace fossil fuels and address pressing issues of energy shortage and serious environmental pollution. In this study, microwave-assisted dilute acid pretreatment was proposed to enhance the enzymatic saccharification of water hyacinth for...

This paper analyzes a spurious regression involving AR(p) infinite-variance processes in the presence of structural breaks by least squares using asymptotic theory. It is found that when regressing two independent infinite-variance sequence with breaks in the level and slope of trend, no matter...
