Many recent game-theoretic models suggest that with asymmetric informa
tion it can be profitable for firms to acquire a reputation for toughn
ess to discourage later entry. We identify institutional arrangements
that firms must undertake if predatory commitments are to be credible.
For example, simply hiring managers who value market share or output
maximization is insufficient if managers can be removed when it actual
ly becomes necessary to engage in predation. Firms must also make remo
ving the manager more difficult. We find no evidence that allegedly pr
edatory firms are organized as these game-theoretic models imply. If a
nything, the reverse seems to be frequently true.
