Convexity, Disposability and Returns to Scale in Production Analysis

Author

Abstract

Adequate modelling of undesirable outputs is a key aspect for any performance analysis of economic systems. A nonparametric approach assuming jointly weak disposability of desirable and undesirable outputs inspired by Shephard (1974) has gained substantial popularity in addressing this issue. Recently, researchers were offered an alternative that is to use multiple scaling factors (rather than a single one as in the Shephard’s (1974) approach) when imposing weak disposability in practice. In this paper we discover new properties and relationships between the two approaches, which in turn sheds some new light on the problem and offers reconciling solutions.
