This paper exams the concept of Pollution-generating Technologies (PgT). The main goal of this methodological contribution is to reveal any PgT in production processes compatible with a minimal set of assumptions. We model PgT using a congestion approach of the output set relaxing strong...

This contribution establishes, from a theoretical viewpoint, the relations between the Malmquist productivity indices, that measure in either input or output orientations, and the Luenberger productivity indices, that can simultaneously contract inputs and expand outputs, but that can also...

This paper defines a new distance function in production theory that generalizes several existing efficiency measures. The new distance function is inspired from the Atkinson inequality index and maximizes the sum of the netput expansions required to reach an efficient point. This article also...
