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 management and organization field, especially on cognition and strategy. 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 has also been essential for the development of the growing field of studies on the construction of markets and categories. In addition to that, Sarah was an amazing guest whose contributions to these discussions (and to this episode!) cannot be understated!
