The notion that managers encounter differing levels of discretion acro
ss industries and organizations is becoming central to discussions of
strategy formulation and implementation. However, discretion can be ex
ercised or created only to the extent it is perceived, and theories of
cognition and decision making suggest that managers' perceptions of d
iscretion may vary significantly. Despite the importance of perception
s to Hambrick and Finkelstein's (1987) theoretical model of managerial
discretion, no empirical tests examining perceived discretion have be
en published to date. Drawing on theories of issue interpretation and
impression management, we find that managers differ systematically in
the amount of discretion they perceive. Specifically, we find support
for the predicted relationship between locus of control, a stable pers
onality difference, and perceptions of managerial discretion. We also
find that perceived discretion predicts managerial power, but only in
situations in which the manager actually has little discretion. The dy
namic model presented and tested here suggests that managers, in part
through impression management activities and their ability to attend t
o critical contingencies, may both increase their power and enlarge th
eir latitude for action. Implications for strategy formulation and imp
lementation are discussed. (C) 1997 by John Wiley & Sons, Ltd.
