Abstract: This paper considers a raw material pricing contract design problem, in which a manufacturer purchases raw materials from a raw material supplier, but the manufacturer’s processing cost is private information. Furthermore, two strategies, named wholesale price and fixed transfer are simultaneously employed in the contract. A raw material pricing contract model is developed with the purpose of maximizing the raw material supplier’s expected payoff, and its equivalent form is obtained. The optimal contracts are obtained under the cases of complete information and incomplete information, respectively. The optimal contracts demonstrate that the optimal purchasing quantity under incomplete information is less than that of under complete information.

Key words: contract, raw material pricing, principal-agent, incomplete information
