Almost two decades later, Burt (1992) developed the boarding of Granovetter through the concept of ' ' holes estruturais' '. Burt arrived to use the term capital stock, as Bourdieu, defining it of instrumental form. In the case of Burt, however, the capital stock seats in the relative scarcity of bows entretecidos in nets, and not in its density. Burt sees the capital stock as: ' ' more general friends, colleagues and contacts through which we accede the chances of use of the proper financial capital or humano' '. work of Loury opened way, however, for an analysis more refined of the same process, taken the handle for Coleman, nominated in what it respects to the paper of the capital stock in the creation of human capital. In its initial analysis of the concept, Coleman receives the contribution of Loury, as the ones of Ben-Porath economist and sociologists Nan Lin and Mark Granovetter. James Coleman left itself to influence, for Granovetter to make its study on capital stock.
He works with the concept of capital stock in an individual perspective and of the rational choices. For Coleman (1986), the capital stock is not a singular entity, but a variety of different entities that possess two characteristics in common: they consist of some aspect of a social structure and facilitate some actions of the individuals that are in the interior of this structure. The capital stock, in this direction, is productive, since it becomes possible that if they reach objectives that would not be reached in its absence. It is the question of the reciprocity. After de Bourdieu, Loury and Coleman, diverse other analyses of the capital stock have been published. In 1990, W.E. Baker defined the concept as ' ' a resource that the actors make to derive from specific social structures and use later for the accomplishment of its interests; resource this servant for alterations in the relation between atores' ' (BAKER, 1990:619).
