A mainstay of stakeholder management is the belief that firms create value when they invest more time, money, and attention to stakeholders than is necessary for the immediate transaction. This tendency to repeat interactions with the same set of stakeholders fosters what we call stakeholder friction. Stakeholder friction is a term for the collection of social, legal, and economic forces leading firms to prioritize and reinvest in current stakeholders. For many stakeholder scholars, such friction is close to universally beneficial, but the associated costs—to both the firm and legitimate stakeholders—have been underspecified. Failure to account for the effects of stakeholder friction can cause managers to under-allocate attention and value to some legitimate stakeholders and to over-allocate attention and value to current stakeholders. We examine the concept of stakeholder friction and elaborate on three exemplar sources of friction prominent in the stakeholder literature. This is followed by an analysis of investments in stakeholder relationships and a consideration of the implications of stakeholder friction on the ability of firms to prioritize stakeholders. The tendency to reinvest in current stakeholders has, in addition to the oft-discussed benefits, a predictable downside.
