A core question in the study of organizations is why people cooperate with
the organizations to which they belong. In this analysis I argue that coope
rative behavior is linked to the role organizations play in defining and ma
intaining people's social identities. People define themselves and evaluate
their self-worth, at least in part, through status judgments linked to the
organizations to which they belong. When people receive favorable identity
-relevant information from membership in an organization they respond behav
iorally by cooperating with the organization-that is, following organizatio
nal rules, acting in ways which help the organization and showing loyalty t
o the organization. Further, people respond to favorable identity-relevant
information by developing internal values that lead them to voluntarily eng
age in such cooperative behaviors. Two identity relevant judgments are dist
inguished: pride and respect. Pride reflects evaluations of the status of o
ne's organization. Respect reflects assessments of how one is evaluated by
others in that organization. Both identity-relevant judgments influence the
extent to which:people engage in cooperative behavior.
