Toward a public administration theory of public service motivation

Abstract Public service motivation (PSM) is a prominent concept within current Public Administration, as it refers to the drive for public interested and altruistic behaviour. Although substantial empirical research on its nature and its impact is available, little is known on the origins of PSM. Led by cues provided by previous empirical research, this article seeks to develop a general theory of PSM, encompassing both causes and consequences of PSM. Based on an interdisciplinary approach, elements of institutional theory and motivational psychology are fused together, blending into an operational theory of PSM.
