Conclusions ABSTRACT Three restricted specifications of a stochastic technology that enable economies of scope to be identified are defined in the study. For each specification, the results of this study exactly parallel those obtained by Panzar and Willig (1981) for defining economies of scope using a non-stochastic technology. Sub-additivity of the individual ex ante cost function of each output is a sufficient condition for multi-output firms operating in a stochastic production environment.
