This paper proposes a trade restrictiveness indicator that explicitly incorporates environmental externalities. The index employs directional distance functions and use indicators (i.e. differences rather than ratios) modified to account for and evaluate efficiency changes in the face of...

This paper develops a slack-based decomposition of profit efficiency based on a direc- tional distance function. It complements Cooper, Pastor, Aparicio and Borras (2011).

This paper analyzes productivity growth in seventeen OECD countries over the period 1979-88. A nonparametric programming method (activity analysis) is used to compute Malmquist productivity indexes. These are decomposed into two component measures, namely, technical change and efficiency change....

This paper builds on earlier efforts to integrate preferences into a DEA model. Rather than including an explicit utility function as a constraint to a DEA problem as in Färe et al. (2002), here we use the notion of dominance to identify a ’¡Ærevealed’¡Ç indifference curve, which is...
