Please join us for Episode 25 as we welcome Prof Sarah Kaplan to discuss another JMS Classic work entitled “Competitive groups as cognitive communities, the case of Scottish knitwear manufacturers”. This paper had a great impact in the field of management and organization in general, and on research in cognition and strategy in particular. As a matter of fact, it has contributed to the vibrant community on managerial cognition which today feeds into many areas of the field. It was also been essential for the development of the growing field of studies on the construction of markets and categories. We are very grateful to Prof Kaplan for joining us for this discussion - she was an amazing guest and a great interlocutor!
