Network models of market competition are used to advance from two sign
ificant research efforts; Lawrence gi Lorsch's (1967) demonstration th
at the optimum form of organization varies between markets, and Kotter
and Heskett's (1992) study of corporate culture and performance. We c
ompare firms in terms of their economic performance, the extent to whi
ch they have a strong corporate culture, and the network structure of
their market. The value of a strong corporate culture varies between m
arkets; nothing in one market, an asset in more competitive markets. F
rom the variation between markets, we build a culture-performance cont
ingency function that uses the network structure of a firm's market to
predict the extent to which a strong corporate culture can be expecte
d to enhance the firm's performance. With the contingency function, an
d market census data, we infer that the correlation between culture an
d performance is strong in the American economy, especially in manufac
turing. We also use the function to identify reasonable samples of org
anizations in which the correlation will be weak, The contingency func
tion is an interesting substantive phenomenon in its own right and a v
aluable analytical tool for generalizing results on sample firms to po
pulation conditions.
