This paper tests the hypothesis that differences in the organizational
form embodied in independent banks, one-bank holding companies, and m
ultibank holding companies result in differences in operating cost eff
iciency. The transaction and agency cost paradigms for analysis of org
anizational efficiency provide theoretical motivation for the hypothes
is. The effects of organizational form on bank operating expenses for
individual banks are evaluated on subsamples divided into quartiles ba
sed on total revenue. Results indicate that for banks having revenues
in the lowest quartile, both one-bank and multibank holding company af
filiates are cost efficient relative to independent banks. Multibank h
olding company affiliates are cost efficient relative to both one-bank
affiliates and independent banks for banks in the interquartile range
. No significant differences in cost efficiency are noted banks in the
highest revenue quartile. Relative efficiency at the organizational l
evel is also evaluated. Results provide evidence of lower operating co
sts for banking operations of both multibank and one-bank holding comp
any organizations relative to independent banks. Taken as a whole, the
results imply that holding company affiliation conveys cost advantage
s to banking units below the 75th revenue percentile.
