Power Gain and Loss: Social Exchange and Strategic Contingencies

Definition

Power changes over time through two mechanisms. Social exchange theory explains how individual leaders gain or lose status and influence: demonstrated competence and loyalty increase "idiosyncrasy credits" (latitude to deviate from norms), while failure diminishes status, especially if failure appears due to poor judgment rather than circumstances beyond control. Strategic contingencies theory explains how organizational subunits gain power by controlling expertise and centrality—subunits with unique expertise for solving critical problems that others depend on accumulate power. Both mechanisms reveal that power is contingent on continuing to deliver value, not a permanent possession of formal position.

In the Book

Yukl explains that leaders earn influence through "demonstrated competence" and "contribution to shared objectives." A leader who successfully solves critical problems gains more than salary and position power—they accumulate idiosyncrasy credits allowing them to propose innovations that violate norms. However, innovation is a "double-edged sword": success increases credit and status, but failure results in greater blame and loss of status. The loss is magnified if failure appears to stem from poor judgment, selfish motives, or pursuit of personal glory rather than loyal service to the group. The book emphasizes the asymmetry: a leader with high status loses more status from failure than a low-status leader, because higher expectations apply. Strategic contingencies theory extends this to subunits: marketing gains power when competitors are the critical threat; manufacturing gains power when production is the constraint. As a problem becomes solved (competitors eliminated, manufacturing automated), that subunit's power declines because the critical contingency it managed no longer exists. Similarly, a subordinate gains power over a superior when the subordinate controls information the superior needs for decisions. This power exists only while the dependence continues; once the superior learns the information or the decision becomes routine, the subordinate's influence evaporates.

Why It Matters

This framework explains why leadership is inherently precarious. Formal position power persists even as demonstrated competence erodes, but actual influence decays. It reveals why high-status leaders are more vulnerable to reputation loss—the investment in their leadership makes failure more costly to the organization's morale and direction. For leaders, it mandates continuous demonstration of value: experts must stay current; leaders must maintain loyalty to followers and organization (not just self-interest); those in charge of critical problems must continue solving them or develop successors, not cling to obsolete roles. For organizations, it explains why divisions and executives decline in power: not through formal demotion but through failure to manage increasingly critical contingencies. It also illuminates political dynamics: as an executive's power base (the critical problem they manage) becomes solved, they desperately try to protect their position—restricting information, preventing rivals from demonstrating superior expertise, or manufacturing crises to prove their continued value. Understanding power dynamics prevents both naive surprise when powerful people lose influence rapidly and cynicism about the instability of organizational positions.
