Private information creates a cost of operating a hierarchy, which bec
omes larger as the hierarchical distance between the information sourc
e and the decision maker increases. When information about a firm's ca
pabilities is dispersed among the individuals in the firm, production
is inefficient even though everyone behaves rationally. Because hierar
chies need rents in order to function, a firm with a long hierarchy ma
y not be viable in a competitive industry.
