英文摘要:
We consider an auction market in which market makers fill the order book during a given time period while some other investors send market orders. We define the clearing price of the auction as the price maximizing the exchanged volume at the clearing time according to the supply and demand of each market participants. Then we derive in a semi-explicit form the error made between this clearing price and the efficient price as a function of the auction duration. We study the impact of the behavior of market takers on this error. To do so we consider the case of naive market takers and that of rational market takers playing a Nash equilibrium to minimize their transaction costs. We compute the optimal duration of the auctions for 77 stocks traded on Euronext and compare the quality of price formation process under this optimal value to the case of a continuous limit order book. Continuous limit order books are found to be usually sub-optimal. However, in term of our metric, they only moderately impair the quality of price formation process. Order of magnitude of optimal auction durations is from 2 to 10 minutes.

中文摘要:
我们考虑一个拍卖市场,其中做市商在给定的时间段内填写订单,而其他投资者发送市场订单。我们将拍卖的结算价格定义为根据每个市场参与者的供需情况,在结算时使交易量最大化的价格。然后,我们以一种半显式的形式推导出该结算价格与有效价格之间的误差,作为拍卖持续时间的函数。我们研究了市场接受者的行为对这一错误的影响。为此,我们考虑了天真的市场接受者和理性的市场接受者通过纳什均衡来最小化交易成本的情况。我们计算了在泛欧交易所交易的77只股票的最优拍卖持续时间,并将此最优值下的价格形成过程的质量与连续限价指令簿的情况进行了比较。连续限制订单簿通常是次优的。然而,就我们的衡量标准而言,它们只会适度削弱价格形成过程的质量。最佳拍卖持续时间的数量级为2到10分钟。
