Design of Outsourcing Contract Considering the Risk Attitude of Both Sides with Asymmetric Information

The outsourcing contract design with both moral hazard and adverse selection was investigated under different risk attitude combination between the client and the provider. Based on the principal agent theory， the contract was designed which was used by the client to motivate the provider’s participation and screen its true private information. Furthermore， the impact of the asymmetric information and risk attitude combination on the corresponding optimal strategies and expected profit were analyzed. The analysis results showed that with dual asymmetric information， the optimal strategies and expected profit of both sides were depended on the risk attitude combination as well as the asymmetric information. The above results also implied the impact of the risk attitude on the decisions of both sides as well as the value of information， and provided the decision support for the outsourcing contract design.
