ABSTRACT
Research on self-organized forms in the management, production and distribution of common goods is a field in which some very interesting attempts have been made towards overcoming explanatory alternatives between macrostructural and microindividual variables in understanding institutional change. The possibility and conditions of emergence of new institutional forms of action are inquired into through an analysis of the constitution and evolution of structures of collective action in the concrete processes of their making (Melucci 1987). As a result of this strategy of research, renewed theoretical approaches to collective action have joined recent contributions to action theory in fostering a radical redefinition of the rationality of individual as well as of institutional action.
