| Abstract: | This paper analyzes the two-period moral hazard model. The optimal long-term contract is derived by optimization programs. A conclusion that the optimal long-term contract under the complete commitment of the memory and martingale properties was given. It also connects the current payment and the future repayment or punishment. A useful basic way for further study for long-term contract is given. |
