2018年11月27日（周二）上午十点，悉尼科技大学何学中教授应邀做客广外金融论坛第三十讲，在我校南校区院系办公楼401室（金融学院会议室）开展主题为“The Microstructure of Endogenous Liquidity Provision”的学术讲座。本次讲座由广东外语外贸大学金融学院、广东省普通高校创新团队项目 “投资管理、期权定价和风险管理”联合主办，我院副院长及团队负责人姚海祥教授主持讲座，马庆华教授、邓超博士、张群博士、周利博士、张琰博士等多位教师和团队成员都出席了本次讲座，我院众多研究生也参加了本次论坛交流和学习。
何学中教授做讲解
何学中教授分享了一个高频交易中内生的流动性供给的微观模型（A Microstructure Model of High-frequency Endogenous Liquidity Provision）以解释当市场的不确定性激增时，在平稳时期所创造的充足流动性会迅速蒸发和消失。研究指出，高频交易者凭借其交易速度和订单流信息的优势，在大多数时间可以提供流动性，然而在市场动荡期间，不确定性的增加将迫使高频交易者停止中介活动，转而要求流动性。这种内生的流动性错配将使得标的资产流动性不足。研究发现，随着市场中高频交易者的信息和速度优势的增加，市场流动性可以得到改善。
现场热烈讨论
本次论坛中，何学中教授和现场师生进行了热烈的交流，学生们认真听讲，表示在本次讲座中受益匪浅。
