Joint production in general and co-production in particular are phenomena that appear only to a very limited extent in the literature on production economics, although they are the norm in the real world. Together with his co-author Harald Dyckhoff, Rainer Souren explores in the prestigious Journal of Business Economics how the terms "joint production", "by-product(ion)" and "undesirable outputs" have been received in the international literature, especially over the past 30 years. In addition to the comprehensive literature review, they also propose a system of terms that enables a more precise analysis of these phenomena, which are particularly relevant for sustainability management.
