将数量折扣引入到具有两件随机等价互补品的序贯二价拍卖中,研究了数量折扣对买者均衡报价策略的影响,建立了卖者如何确定最优的折扣比例的数学模型并得到了最优的折扣比例。研究表明:采用适当的折扣比例可以激发买者之间的激烈竞争,卖者的期望收益也可以得到提高,买者人数越多最优折扣比例越小。
將數量摺釦引入到具有兩件隨機等價互補品的序貫二價拍賣中,研究瞭數量摺釦對買者均衡報價策略的影響,建立瞭賣者如何確定最優的摺釦比例的數學模型併得到瞭最優的摺釦比例。研究錶明:採用適噹的摺釦比例可以激髮買者之間的激烈競爭,賣者的期望收益也可以得到提高,買者人數越多最優摺釦比例越小。

Quantity discount is introduced into sequential second-price auctions with two stochastically equivalent complementary objects. We study the impact of quantity discount on the buyers’ equilibrium bidding strategies, set up the mathematical model for the seller to choose the optimal discount ratio and obtain the optimal discount ratio. Our study shows that: adopting discount ratio induces intense competition among the bidders, adequate discount ratio can increase the seller’s ex ante expected revenue and optimal discount ratio decreases as the number of bidders increases.
