| Research Abstract |
First, as for the risk management by banks, we have solved for an optimal timing and scale of asset securitization. The model’s implication turns out to be consistent with the trends of securitization during asset price bubbles and financial crises. Moreover, we have constructed a model to obtain the best timing to initiate credit enhancement program. It is useful especially when the bank is experiencing rapid deterioration of their loan portfolio. Next, as for the bank supervision, we have constructed a theoretical model of prompt corrective actions and shown when the regulator takes into consideration the social costs of bank failures, the optimal intervention depends on the bank’s initial capital level, and that the social welfare costs depends on government subsidies as well as the intervention.
