This study applies the concept of institutional logic to interpret the content of the instrumental and expressive dimensions of nonprofit organizations (NPOs). The study concludes that the three-sector assumption of public, private, and nonprofit in existing nonprofit studies may have neglected some institutional logics of NPOs. The sets of institutional logics that are innate to NPOs must often adapt to “external” institutional logics due to resource dependency. The study discusses a relatively complete spectrum of the multiple institutional logics enacted by NPOs, and it conceptualizes the “adapted institutional logics” phenomenon, whereby NPOs are forced to change due to competing logics.
