Boone ct al. (1996) reported that Chief Executive Officer (CEO) locus of co
ntrol Department uf was significantly associated with profitability in a cr
oss-sectional study of 39 small finals. As the authors could not rule out t
he possibility that firm performance causes Sciences, an internal locus of
control rather than the other way around, a follow-up study was performed t
o provide us with a possible clarification of the direction of causation. W
e traced the life history of each of these 39 firms and analyzed the relati
onship between locus of control and long-run organizational survival. We fo
und that 21 percent of the 39 firms studied in Boone ct ai. (1996) went ban
krupt within 6 years. Among the CEOs classified as internals, only 1 compan
y failed (1 out of 14), whereas among the external CEOs 45 percent did not
survive (5 out of 11). We also found that the differences between internal
and external CEOs were only observable for firms that were relatively unpro
fitable in 1990-1991, indicating that short-term performance shields the co
mpanies from subsequent bankruptcy. We conclude that our findings suggest t
hat CEO locus of control is an important predictor of small firm performanc
e.
