This paper aims to propose a new perspective on necessity entrepreneurship (NE). This phenomenon is indeed widely considered in the literature as having no or a negative impact on economic growth and is therefore mostly depreciated by scholars. We argue that NE allows to socially integrate deprived individuals and increases their psychological and human capital, if adequate structures and public policies are in place. We have opened a new venue, in considering for the first time NE in the perspective of a knowledge development process, calling for a differentiated approach. Although NE proves to play a limited impact on shrinking unemployment, fighting poverty and reducing discriminations, its social role as inclusive tool for deprived individuals has been underestimated: efficient entrepreneurial knowledge management, skills and competencies development in a constrained context can have a positive impact on individuals and societies.
