[2] Gadde obtained his PhD at the University of Gothenburg in 1978 with the thesis, entitled "Efterfrågevariationer i vertikala marknadssystem" (Demand variations in vertical marketing systems).
One reason for the slight research interest is that up to the 1970s many industries could be characterised as operating in a 'seller's market.'
[5] Soon after he joined the Industrial Marketing and Purchasing Group, and much of his research and publications has been under their wings.
In the 1990s he also published some works on case study research in cooperation with Anna Dubois of the Chalmers University of Technology.
Gadde's research interest has remained in the field of "exchange processes among companies in business networks.
