基于梯形分布的一级密封价格拍卖博弈及均衡分析

First-Price Sealed Auction Price Game and Equilibrium Analysis Based on Trapezoid Distribution

针对传统的一级密封价格拍卖博弈模型中条件假设的不足,结合生活中实际拍卖的特点,运用梯形分布的思想,对经典的一级密封价格拍卖博弈模型做了改进.与改进前的模型相比,改进后的模型结果与现实的吻合性更好,更具有现实指导意义.

This paper improves the traditional first‐price sealed‐bid auction model and makes some compari‐sons between the models by using the idea of trapezoid distribution ,which aims at overcoming the short‐age of the traditional first‐price sealed‐bid auction model and combines the characteristics of the actual auc‐tion in life .The final results show that compared with the traditional model ,the improved model can bet‐ter reflect the real situation and hence has certain realistic directive significance .
