This paper develops a general model of response to loss. Based on original
empirical research of the U.S. auto industry and dual literature analyses o
f macro-organizational behavior and clinical psychology, I observe that org
anizational response to major environmental change is remarkably similar to
individual response to loss. To explain this similarity, I propose that a
common identity maintenance and adaptation imperataive drives the process a
t all social levels through all phases. I explain loss as a chasm between t
wo forms of identity-structural and cognitive-that a viable entity must hol
d in some reasonable congruence:. The analysis suggests a logic underlying
Kubler-Ross's (1969) stage theory of loss:, a model that has enjoyed widesp
read clinical acceptance but has met with scientific skepticism. Based on t
his stage theory, I develop a modified, general model of loss that explains
important anomalous findings about loss including loss aversion, escalatio
n, and rigidity under threat, and, more generally why it usually takes so l
ong to respond and adapt. Practical applications for understanding and mana
ging change processes are proposed.
