War as a Phenomenon of Inquiry in Management Studies
Journal of Management Studies, Volume 63, Issue 6, Page 2363-2397, September 2026.Abstract We argue that war as a phenomenon deserves more focused attention in management. First, we highlight why war is an important and relevant area of inquiry for management scholars. We then integrate scattered conversations on war in management studies into a framework structured around three building blocks – (a) the nature of war from an ...
