Finally, under centralized supervision, only the central supervisor collects information and decides on the liquidation of the bank.
The model of hierarchical supervision is compared in terms of welfare with two alternative arrangements, namely decentralized supervision, where the local supervisor is fully in charge, and centralized supervision, where the central supervisor is fully in charge.
Thus, the liquidation cost of the local supervisor will be (delta _{l}+Delta ) under decentralized supervision and (delta _{l}) under hierarchical supervision, whereas the liquidation cost of the central supervisor will be (Delta ) under both centralized and hierarchical supervision.
This hierarchical model is contrasted with the alternatives of decentralized and centralized supervision, where only the local or the central supervisor collects information and decides on liquidation.
The higher the cost of effort of the central supervisor (gamma _{c}) the lower the likelihood that centralized supervision will be optimal, because as shown in Fig. 3a the central supervisor will have an incentive to exert too little effort.
This setup may be interpreted as a model of decentralized supervision in which supervisory responsibilities are allocated to a local supervisor or a model of centralized supervision in which supervisory responsibilities are allocated to a central supervisor.
