银行卡平台营利性质对投资激励的影响

构建了基于双边市场理论的投资策略模型,分析了银行卡平台营利性质对平台投资者的投资激励的影响,发现在差异化营利市场条件下,非营利性银行卡平台具有更强的投资激励效应。同时,利用2002～2011年全球主要银行卡公司财务数据对投资激励效应的性质和强度进行了实证检验。在一定程度上解释了现实经济中非营利性银行卡平台的融资规模高于营利性银行卡平台的原因。     

投资者会听话听音吗??--基于管理层语调视角的实证研究

我国投资者会听话听音吗？文章利用文本分析方法,基于我国上市公司2005－2012年年度业绩说明会上的管理层语调数据对此进行了实证检验。研究发现,投资者对管理层的净正面语调做出了显著的正向反应,尤其是对负面语调做出了显著的负向反应。这表明在我国强调“意会”的语境文化背景下,投资者会听话听音,管理层语调具有信息含量,上市公司的业绩说明会具有其自身的存在价值。文章的研究结果还意味着,“词袋”方法及其构建的管理层语调用词列表在我国儒家文化背景下具有一定的适用性,值得开展进一步的研究。     

基于状态空间模型的我国物流业对经济增长的传导效应研究

建立状态空间模型来揭示物流业对经济增长传导效应,通过卡尔曼滤波算法估计时变参数,发现1978年以来我国物流业对经济增长的传导效应明显分为两个阶段,并在此基础上提出了物流产业转型期提高物流业对经济增长传导的正弹性效应、发展物流业的路径选择。     

物流业与三次产业发展的互动关系实证研究

以物流业和三次产业为研究对象,运用计量经济理论的模型和方法,对中国1978～2009年物流业与三个产业发展的协整与因果互动机制进行了实证分析。研究结果表明:从协整检验和误差修正模型看,中国物流业与三次产业之间呈现出比较稳定的长期均衡发展趋势,短期波动也起着正的影响作用;从格兰杰因果关系检验看,中国物流业与第一产业和第二产业有单向的因果关系,与第三产业有双向因果关系。     

Order aggressiveness and order book dynamics

In this paper, we study the determinants of order aggressiveness and traders’ order submission strategy in an open limit order book market. Applying an order classification scheme, we model the most aggressive market orders, limit orders as well as cancellations on both sides of the market employing a six-dimensional autoregressive conditional intensity model. Using order book data from the Australian Stock Exchange, we find that market depth, the queued volume, the bid-ask spread, recent volatility, as well as recent changes in both the order flow and the price play an important role in explaining the determinants of order aggressiveness. Overall, our empirical results broadly confirm theoretical predictions on limit order book trading. However, we also find evidence for behavior that can be attributed to particular liquidity and volatility effects.

Dynamic relationship between stock market trading volumes and investor fear gauges movements

This article applies multifractal detrended fluctuation analysis (MF-DFA) and multifractal detrended cross-correlation analysis (MF-DCCA) to investigate cross-correlation behaviours between two kinds of stock markets trading volumes and investor fear gauges covering the data of U.S. stock markets from 2 January 2004 to 31 July 2018. The empirical results show that the dynamic relationship between stock markets trading volume fluctuations and different kinds of investor fear gauges are multifractal and find that the dynamic relationship is strongly anti-persistent. Moreover, financial crisis in 2008 has a significant impact on the cross-correlated behaviour, suggesting that stock market trading volume fluctuations and investor fear gauges are more susceptible to each other during the financial crisis period. Through the rolling windows analysis, we also find that the stock markets trading volume fluctuations and different kinds of investor fear gauges are anti-persistent dynamic cross-correlated.     

Central Bank Actions and Words: The Intraday Effects of FOMC Policy Communications on Individual Equity Volatility and Returns

We compare intraday impacts of the release of Federal Reserve decision announcements and of Federal Open Market Committee minutes between 2004 and 2015 on 1,997 equity return and volatility series. We find that returns are unresponsive to either news release, but conditional volatility increases for both, manifesting immediately after each information release, and persisting for 30 minutes post‐announcement. These effects are larger for decisions than for minutes. On stratifying firms by trading intensity, we find most “high trading intensity” firms respond to these announcements, while “low trading intensity” firms are less affected. Our results show that traders respond, albeit differently, to both sets of information releases.     

我国房地产金融业存在的问题和对策

我国房地产金融存在的问题主要归结为制度缺陷,集中表现在资金来源渠道单一、房地产金融体系不完备、资金融通效率低下和风险高度集中。这些缺陷很大程度上制约了中国房地产业的长期健康发展,应该通过金融体制的改革,建立开放统一的房地产金融体系。同时,在房地产金融体系不完备的情况下,政府应谨慎出台房地产调控政策,以保护房地产业健康发展。     

Prices and market structure: an empirical analysis of the supermarket industry in Chile

This article investigates empirically the relationship between market structure and consumer prices in the supermarket industry in Chile. A panel of monthly data from 16 cities in the period January 1998–September 2006 is used. We find that, the more concentrated the industry in a city, the higher the prices, while the participation of major national chains in cities tends to lower prices. In terms of magnitude, this latter effect prevails over the former. Moreover, the dominant local chain is found to behave differently depending on whether or not one of the national chains is present in the city. Finally, we find that prices rise when a national chain acquires another chain and both were previously in a city (inmerge) while if only one of the two was present (outmerge), prices fall.
