This paper examines the impact of the bank orientation on classical banking business, distinguishing between shareholder and stakeholder banks, and analyzes the preconditions for positive social welfare effects from the existence of stakeholder banks. For this reason we develop a theoretical bank decision model based on the utility approach and focus on the determination of the interest margin. Vis-à-vis previous studies, we connect to the recent literature on the agency view considering the lessons from recent financial developments. Moreover, we study the influence of the social mission on the bank pricing strategy, merging these two different fields for the first time. The results highlight the fundamental role of a strict and prudential regulation of the social mission as well as of the existence of internal and external control mechanisms, in order to avoid a misuse of stakeholder banks for distorting aims, to increase the system stability and to reduce market failures. Therefore, a correct implementation of these aspects represents a precondition for a positive contribution of stakeholder banks to the social welfare.
