Study On Credit-risk Decision Mechanism With Imperfect Information

This dissertation presents and investigates the credit-risk decision mechanism (CRDM) for the first time. This dissertation introduces the theory and method of incentive mechanism design into the research of CRDM for the first time; first establishes the models of CRDM under incomplete information environment based on the minimization of credit risk; makes some academic and methodological discussions about CRDM based on the diverse backgrounds of the discussed issues; and then brings forward some referential ideas for the practical application of CRDM. Moreover this dissertation does some research on CRDM from the aspects of opportunity benefit. The main points of this dissertation are:1. Dividing the lost of the credit money of bank into: lose of the money (namely the credit money can not be called back partly or totally); the opportunity lose of the money (namely the banks haven't loan the money based on the wrong judge). The distinguish is used in the research of CRDM from the aspect of credit money risk minimization.2. Introducing the theory and method of incentive mechanism design into the research of CRDM, establishing the CRDM models with both incentive compatibility constraint and individual rationality constraint based on the diverse backgrounds of the discussed issues; putting forward CRDM under incomplete information environment.3. Attaching importance to the analysis of practical case: not only using the pure theory in the practical application but also brings forward some referential ideas for the practical application.The main content and achievement of this dissertation are:In Chapter 1, the dissertation investigates the necessity and importance of the CRDM under incomplete information environment, introduces the incentive mechanism design theory, the bank credit risk and its behavior, the reasons of the...
