For Coleman the capital stock must be understood as a resource for the people and, being thus, it is produced from the changes of the interpersonal relations that facilitate definitive actions; on this form, the capital stock depends on the individual action for the production of a collective good and is supported by two pillars, the confidence and the reciprocity. Most interesting in this perspective he is that those that generate capital stock is benefited only of a small part of the all that was produced (COLEMAN, 1999:39). The concept of capital stock presents as a primordial component in the production of bows of reciprocity inside of groups or communities, being that its ticket of the level micron for the macro not yet is identifiable for the instruments and analyses of current social science. This is a question that deserves a deepened quarrel, in view of the fact that studies as of Putnam (1997) support this argument. Although the identification of the capital stock in described events for Coleman, is necessary to identify, by means of the conceptual treatment, who is the possessors of capital stock, which is the sources of capital stock and which are the resources of capital stock (Transports, 2001:47).
Moreover, she is necessary to analyze if the constitution of social bows can lead to the creation of social structures where the result of its dynamic can be the corrosion of the proper capital stock in relation external groups. The scientist politician Robert Salisbury advanced the term as a critical component of interest group formation in 1969 its article ' ' An Exchange Theory of Interest Groups' ' in the Official Midwest of Sciences Politics. Pierre Bourdieu used the term in 1972, its Sketch of a Theory of the Practical one, and clarificou the expression some years later, in cultural contrast with, the economic and symbolic capital.
