Using the stochastic frontier analysis model, we estimate TFEE (total-factor energy efficiency) scores for 47 regions across Japan during the years 1996–2008. We extend the cross-sectional stochastic frontier model proposed by Zhou et al. (2012) to panel data models and add environmental...

This study computes the pure technical efficiency (PTE) and energy-saving target of Taiwan's service sectors during 2001–2008 by using the input-oriented data envelopment analysis (DEA) approach with the assumption of a variable returns-to-scale (VRS) situation. This paper further investigates...

In order to decrease the detrimental effects from global warming, the European Union (EU) has started to control CO2 emissions by allocating CO2 emission allowances to 25 member states. In this study we are interested about the effects of CO2 emission allowance on environmental efficiency,...
