Technological capability, transactional capability and firm boundaries [PDF]
Suma de Negocios, 2021 Although there is research pertaining to the boundaries of firms, this field of study still requires more development. The objective of this paper is to analyse firm boundaries considering technological and transactional capabilities. The method chosen was that of multiple case studies conducted in firms having different technological intensity levels.
