For strategic and competitive insights, this study measures and benchmarks the comparative operating efficiencies of insurance companies in Taiwan and mainland China. We employ the two-stage DEA with the bootstrapped truncated regression approach to examine the overall efficiency of insurance...

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,...

This paper measures the metafrontier total-factor energy efficiency (TFEE) of 47 regions in Japan for the period 1996–2008, using the stochastic frontier analysis (SFA). The two-step output-oriented SFA approach by Huang et al. (J Prod Anal 42:241–254, 2014) is followed but converted into a...
