As rational choice theory has moved from economics into political science and sociology, it has been dramatically transformed. The intellectual diffusion of agency theory illustrates this process. Agency theory is a general model of social relations involving the delegation of authority, and generally resulting in problems of control, which has been applied to a broad range of substantive contexts. This paper analyzes applications of agency theory to state policy implementation in economics, political science, and sociology. After documenting variations in the (...) theory across disciplinary contexts, the strengths and weaknesses of these different varieties of agency theory are assessed. Sociological versions of agency theory, incorporating both broader microfoundations and richer models of social structure, are in many respects the most promising. This type of agency theory illustrates the potential of an emerging sociological version of rational choice theory. (shrink)

Akrasia is a philosophical concept meaning the possibility to perform actions against one's best judgement. This contribution aims to clarify this phenomenon in terms of a social construction, stating it as a narrative configuration generated by an observer. The latter finds himself engaged in justifying a “problematic” line of action with regard to specific cultural beliefs referring to the self, the others and the behaviour. This paper intends to make explicit the assumptions underlying the traditional definitions of akrasia when, paradoxically, (...) an agent performs an action not in accordance with his/her best judgement. In the transition from modern to post-modern psychology, we here propose an interpretation of the phenomenon in psychological terms, envisaging akrasia as a narrative form functional to the identity processes and to the social dynamics of the structures of contemporary societies. Implications in the psychological practice will be taken into account. (shrink)

Soka Gakkai is one of the world’s fastest-growing religious movements and Italy figures among the western nations where this religious group has been most successful. This article aims at explaining this success-story: why has Soka Gakkai, and particularly its Italian affiliation, grown so rapidly in recent years? This research question gives the opportunity to assess the applicability of the economic theory of religion to the growth of new religious movements. Hence, in order to explain the expansion of Soka Gakkai, this (...) work begins with an examination of the adaptive strategies developed by a Japanese organization in the Italian religious market. It is claimed, however, that a rational choice explanation cannot stand on its own and that we must take into account the dynamics of pre-contractual solidarity that promote trust, especially when the expected benefits promised by this organization to its adherents do not materialize. Moreover, these solidarity dynamics generate intense emotional gratification that works as a highly motivating incentive to sustain members’ commitment and to prevent them from dropping out. This pre-contractual solidarity is actively produced and continuously reproduced by means of ritual interaction along the lines suggested by Collins’s theory. (shrink)
