ABSTRACT
Decades after seminal works by Coase and Hayek there is neither a unified theory which is able to give an universally accepted definition of firm, nor individual and collective (firms, organizations) capabilities and competencies which are univocally defined. Thus, it is not surprising the conclusion by Garrouste and Saussier (2005), in treating main themes tackled by the more recent theories of firms,1 that the question “What is a firm?” is still a theoretical challenge, while the research agenda is full of topics to be sharpened.
