Qualification: Financial Intermediation and Delegated Monitoring
Douglas Diamond studies a financial intermediary. His model treats monitoring information as an input that resolves incentive problems between borrowers and lenders. Delegation creates an additional cost because lenders must motivate the intermediary to monitor. Diversification within the intermediary reduces that cost, even under risk neutrality. Scale matters. Monitoring can therefore become economically viable when institutional scale changes the cost of producing credible oversight, which qualifies Kaal's classification of monitoring as a production-economics question. The correspondence is bounded. Diamond studies lenders, borrowers, and financial intermediaries rather than autonomous agents. He does not analyze Kaal's validation architecture or any specific funding mechanism. The model does not show that monitoring supports itself at every scale. It identifies conditions under which delegation reduces monitoring and incentive costs. Kaal's production-economics question remains empirical for the reference mechanism.
