We analyze the equilibrium conditions in which contracts are desirable for firms (buyers) with various levels of management efficiencies procuring a factor input under two levels of quality from supplies. The quality of the factor input, which affects production efficiency, may be known to the buyer; the efficiency of the firm is not known to the supplier. We estimate, using principal-agent models, that firms with high-management efficiency do not have the incentive to pay a quality premium to suppliers, but firms operating with low management efficiency are willing to offer a price premium for quality. The model is applied to the question of preconditioning cattle for the feedlot.
