Purpose - This chapter provides a framework that captures the fundamental impacts of power at the individual, dyadic, small
group, and organizational levels. Within each level, we trace the psychological, cognitive, and behavioral consequences of
having or lacking power.
Approach - We integrate theoretical approaches from psychology, sociology, behavioral economics,
and organizational theory to underscore the far-reaching effects that power has.
Findings - We review theoretical
and empirical evidence that demonstrate that (a) power leads people to take action, increases their general sense of control,
and shape the way they construe the world; (b) power anesthetizes people to other people's emotions and immunizes them from
the pressures of conformity; and (c) power differences within groups may facilitate group functioning by creating order, reducing
conflict, and facilitating coordination. In addition to providing a framework for existing research on power, we also provide
three research directions in hope of generating fruitful future research.
Originality/value - Through a careful review
of the literature, we demonstrate that power helps people know who does what, when, and how.
