Social Dimensions of Individualistic Rationality

We re-examine the introduction of social dimensions into the economic conception of individual rationality. Most contributions in this area adopt the rational utility maximizer by adding social aspects into the domain of the agent's consideration. Thus, an inconsistency is created between sociality and opportunism. We overcome this by employing the Weberian distinction between instrumental and expressive rationality. It does not require the increase in the domain of agent's considerations and it captures society in a richer way with heterogeneity of social attitudes both to society as a system and to its management.
