The purpose of this paper is to develop models with and without emissions trading and to compare industry profits under the two regimes. The model in which emissions trading is permitted is a nonparametric industry frontier model in the spirit of Fare, Grosskopf and Li (1992). It is relative to...

This paper introduces an intertemporal variable cost indirect technology which permits technological change over time, as well as allowing for intertemporal financial flexibility. It characterizes firms or agencies which maximize outputs or services subject to a budget constraint. We define...

This paper critiques a recent attempt to model pollution prevention using data envelopment analysis (DEA). We contribute an alternative model which explicitly models joint provision of desirable and undesirable outputs (a la Shephard and Fare (1974)), using weak disposability of output. We also...

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...
