【摘要】：针对现实拍卖中卖方通常将拍品委托给拍卖行进行拍卖,建立了带佣金率和保留价的一口价拍卖模型.运用博弈理论,首先分析了投标者的均衡策略,然后在给定佣金率的前提下研究了卖方的最优保留价和最优一口价,接着在给定保留价和一口价的前提下研究了拍卖行的最优佣金率研究发现:与不考虑佣金率的情形不同,在考虑佣金率的模型中,一口价有正的概率被投标者选择,即卖方在拍卖中设置一口价可以提高其收益,且卖方的最优保留价大于不设置一口价的模型中的最优保留价;拍卖行的最优佣金率小于不设置一口价的模型中的最优佣金率.
[Abstract]:The seller usually entrusts the lot to the auction house to carry on the auction in the realistic auction, and establishes the one-mouthed auction model with commission rate and reserve price. Based on the game theory, the equilibrium strategy of the bidder is first analyzed, and then the optimal reserve price and the optimal price of the seller are studied under the premise of the given commission rate. Then we study the optimal commission rate of the auction house on the premise of given reserve price and one price. It is found that different from the case of not considering commission rate, in the model of considering commission rate, there is a positive probability of a price being chosen by the bidder. That is, the seller's best reserve price is larger than the optimal reserve price in the model without one price, and the optimal commission rate of the auction house is less than the optimal commission rate in the model without one mouthful price.
