This paper proposes a new two-step stochastic frontier approach to estimate technical efficiency (TE) scores for firms in different groups adopting distinct technologies. Analogous to Battese et al. (J Prod Anal 21:91–103, <CitationRef CitationID="CR4">2004</CitationRef>), the metafrontier production function allows for calculating...</citationref>

Using the stochastic metafrontier framework of Battese et al. (J Prod Anal 21:91–103, <CitationRef CitationID="CR5">2004</CitationRef>), this study proposes to compare and measure the cost efficiency and cost frontier gap between the banking industry in Taiwan and China. It further identifies environmental variables that determine...</citationref>
