简介：在这份报纸，我们分析定价决定和依靠异构的出售力量在二个时期卖它的产品的一个公司的赔偿策略。卖能力的出售代理人是他们的私人信息并且将决定卖努力的代理人的有效性。我们介绍三赔偿合同策略，即分享，分开半、分开公司能在时期一并且由使用原则代理人理论采用，在每策略在二个时期为公司导出最佳的赔偿合同和最佳的价格。比较这三合同策略，我们发现为公司的最佳的策略取决于折扣因素。我们证明公司将肯定出现在为某小折扣因素，并且为分享合同的某大折扣因素的时期一分开合同肯定在时期一被规定。然而，分开半的合同可以被考虑因为一些调停打折因素，并且不能也在时期一为所有折扣因素出现。当分享合同在时期一被提供并且当分开合同在时期一被提供时，与折扣因素增加时，我们的分析也表明最佳的价格与折扣因素减少。
