利用期权的博弈分析管理国家助学贷款

Using the Game Theory Analysis of Options to Manage the National Student Loan

针对国家助学贷款信用风险高的问题,引入期权的博弈分析方法,设计一种国家助学贷款的偿还模式,这种还款模式可以看作有着延展期限的敲出期权,通过借贷双方博弈分析得出结论:借款者通过付费延长贷款的生命期,选择违约边界;贷款者通过调整利率影响借款者的选择,使贷款合同保持激励作用。这种利用期权的博弈分析方法管理国家助学贷款可以有效避免借款者违约,减少银行的贷款风险。

For the high credit risk of National Student Loan, we introduce the option game analysis, design a reimbursement model. This model can be seen as the Knock-out Option with extending the time limit. By game analysis of options, a conclusion is drawn： the borrowers extend the loan period and choose the default threshold by charged; the lenders adjust the rate to influence the choosing of the borrowers, and keep the contract incentive effect. So using the game theory analysis of options to manage the National Student Loan can avoid default of the borrowers, reduce the loan risk of bank.
