The impact of time duration between trades on the price of treasury note futures contracts

Recent research in finance has indicated that the institutional structure in which financial asset prices are determined can have a nontrivial impact on pricing. This report examines transaction level data for Treasury Note futures contracts traded at the Chicago Board of Trade (CBOT) to identify institutional, or market microstructure, impacts on the pricing of these contracts. Relatively few articles have conducted empirical research on the microstructure of U.S. futures trading due to the limited availability of comprehensive transaction level data from the futures exchanges. This report uses the CBOT's Computerized Trade Reconstruction database, a comprehensive transaction level dataset, to identify the price impact of the time duration between trades in a manner analogous to that of A. Dufour and R. F. Engle (2000). Unique differences from prior research include the application to futures contracts with their relative higher frequency of trading, as well as the investigation of the price impact of the number of active traders present on the trading floor and the trading volume. Subsequent price and sign of trade significantly relate to the time duration between trades, the number of floor brokers, and the trading volume. © 2004 Wiley Periodicals, Inc. Jrl.

优化我国产融生态链的若干思考

现代经济已日趋复杂，经济风险也日益增大。寻找产融生态链新形式的必要性已经 不仅仅是为了筹集资金，更增加了一层防范风险的需要。为此，政府必须努力改善产融生态链，重塑金融机构和企业的关系。在借鉴发达国家产融生态链的经验基础上，提出了优化我国产融生态链几点建议。     

论普通商事仲裁管辖对法院管辖的排除

有效的仲裁协议是仲裁机构受理商事纠纷的前提，也是排除法院管辖权的依据。当事人有关仲裁协议有效性的争议将会动摇仲裁管辖的基础。本文从分析仲裁管辖的依据入手，探讨了仲裁管辖与法院管辖之间的界限，结合国际上仲裁管辖制度的最新发展，提出我国应进一步放宽对仲裁管辖权的限制，以促进仲裁事业的发展。     

企业竞争中的博弈分析

论价值链会计管理框架

本文从价值链理论与会计管理理论出发,分析了一个基于价值链分析的会计管理框架,该框架以时间序列为基础,并结合了不同价值链的特点,具体包括事前的预测、决策和预算,事中的实时管理与控制,事后的分析与考评。与已有文献不同的是,本文对该框架的分析深入到了具体的组成部分与运行机制。

东江人与辛亥革命

在近代历史进程中,东江籍人士以炽热的爱国精神和革命行动为辛亥革命作出了有目共睹的贡献：他们加入革命组织,从事舆论宣传,募捐斗争经费,进行武装起义,参与武昌革命及东江光复,捍卫共和大业,凡此种种,均在历史上留下了光辉的一页,值得后人铭记。     

福利危机与改革路径——20世纪90年代以来的香港社会救助

作为全球最活跃的经济体之一,香港一直坚持低税制、低福利、高发展的路线,并根据自身情况建立了一套具有香港特色的社会救助制度。但是,20世纪90年代后,经济、社会等领域发生的重大变化导致这一制度面临诸多问题。为此,香港政府进行了一系列改革,改革汲取了当代全球先进福利理念及经验,在许多方面突破了单纯强调收入援助的传统救助模式,而转向一种新的具有社会投资倾向的积极救助模式。     

Learning equilibrium mean-variance strategy

We study a dynamic mean-variance portfolio optimization problem under the reinforcement learning framework, where an entropy regularizer is introduced to induce exploration. Due to the time–inconsistency involved in a mean-variance criterion, we aim to learn an equilibrium policy. Under an incomplete market setting, we obtain a semi-analytical, exploratory, equilibrium mean-variance policy that turns out to follow a Gaussian distribution. We then focus on a Gaussian mean return model and propose a reinforcement learning algorithm to find the equilibrium policy. Thanks to a thoroughly designed policy iteration procedure in our algorithm, we prove the convergence of our algorithm under mild conditions, despite that dynamic programming principle and the usual policy improvement theorem failing to hold for an equilibrium policy. Numerical experiments are given to demonstrate our algorithm. The design and implementation of our reinforcement learning algorithm apply to a general market setup.
