Time and the Process of Security Price Adjustment

This paper delineates the link between the existence of information, the timing of trades, and the stochastic process of prices. We show that time affects prices, with the time between trades affecting spreads. Because the absence of trades is correlated with volume, our model predicts a testable relation between spreads and normal and unexpected volume, and demonstrates how volume affects the speed of price adjustment. Our model also demonstrates how the transaction price series will be a biased representation of the true price process, with the variance being both overstated and heteroskedastic.     

房地产价格失调与时变货币政策立场识别

本文采用异方差时变参数模型和两步极大似然估计法来探讨短期利率对房价失调反应的时点和特征。研究表明,短期名义利率从2011年第二季度开始钉住滞后房价失调,但没有钉住预期房价失调,体现出货币政策对房价失调反应的“被动性”和“阶段性”特点,说明央行对房市的态度已转变。进一步通过分析具体的调控措施,发现央行在2011年后的利率调整措施与同期的房市宏观调控政策呈现“双向调整”和相互配合的状态。     

浅析虚假贸易融资对实体经济外贸的影响及对策

虚假贸易融资,又称无真实交易背景的贸易融资,突出表现为套利者以虚构货物贸易为基础,利用境内银行担保获得境外融资,并借助货物贸易渠道调回境内结汇,达到套取非法收益、骗取补贴等目的。

中国——东盟自由贸易区的老中贸易效应研究

本文利用引力模型对1990-2009年期间老挝和中国的贸易数据进行分析,考察中国-东盟自由贸易区(CAFTA)的建立对老挝和中国之间进出口贸易的影响.实证结果表明:CAFTA的建立显著促进了老挝对中国的出口,老挝自中国进口量的增长并不显著.     

最小报价单位对证券市场流动性的影响

目前世界上主要交易所基本上是采用十进制的报价方式，但是对不同的股票价位，其最小报价单位还有一定的区别。这从一个侧面反映了最小报价单位对市场质量的影响还有待进一步研究。     

The Price Impact and Survival of Irrational Traders

Milton Friedman argued that irrational traders will consistently lose money, will not survive, and, therefore, cannot influence long‐run asset prices. Since his work, survival and price impact have been assumed to be the same. In this paper, we demonstrate that survival and price impact are two independent concepts. The price impact of irrational traders does not rely on their long‐run survival, and they can have a significant impact on asset prices even when their wealth becomes negligible. We also show that irrational traders' portfolio policies can deviate from their limits long after the price process approaches its long‐run limit.     

Time Patience and Specialization Patterns in the Presence of Asset Trade

Specialization patterns in an open-economy two-sector growth model with endogenous capital accumulation are examined in the presence of free international lending and borrowing. Without free international lending and borrowing it is known that, whereas the less (time-)patient country decumulates real capital, the more patient country accumulates real capital and eventually specializes in a capital-intensive industry. However, free trade of international financial assets causes a dramatic change in long-run specialization patterns. In this case the less patient country may well specialize in the capital-intensive industry and the more patient country in the labor-intensive industry.

The Trade-off Between the Selling Price of Residential Properties and Time-on-the-Market: The Impact of Price Setting

When a house is placed on the market, the seller must choose the initial offer price. Setting the price too high or too low affects the marketability of the property. While there is near universal agreement that the seller faces a trade-off between selling at a higher price and selling in less time, there is less agreement about how to measure this trade-off. This paper offers a framework for analysis and shows that an increase in the list price increases expected time-on-the-market (TOM). Because house buyers must solve a type of signal extraction problem, the effect of a higher list price is magnified for houses in a market segment having a low predicted variance of the list price. This paper also shows that the list price of houses which are withdrawn before sale has a higher mean and variance, and that the possibility of withdrawal censors information about the time-on-the-market.     

国际金融市场利差套利对人民币、港元的冲击

国际金融市场上的利差套利对人民币产生了很大的冲击,虽然目前人民币还不可自由兑换,但套利资金通过各种途径进入到中国,在欧债危机中人民币与欧洲债券很高的相关系数显示出这点.本文通过港元为媒介,探索套利资金可能的进出途径,根据历史数据建立相应模型,找出其中的脉络并提出相应对策.根据利率预期效应、资产套利预期效应,发现套利资金的流向是长期的资本市场如房产市场等,使得我国的房地产调控政策具备了应对境外投机资金冲击的属性.     

中美贸易摩擦对国际贸易板块的冲击--基于事件研究法

中美建交40周年以来,中美经贸关系既有合作又有摩擦。自2018年3月美国向中国部分商品加征关税,中美贸易战正式打响,中美贸易摩擦持续升级,导致国际贸易板块剧烈波动,引发投资者恐慌情绪。本文基于事件研究法,分析"正面"和"负面"中美贸易摩擦新闻事件分别对国际贸易板块的影响,首先通过对"窗口期"平均异常收益率进行分析,为投资者分别提供在中美贸易新闻"正面""负面"事件冲击下利用股市"T+1"交易机制对国际贸易板块进行投资时获利的最佳投资点;其次通过对"窗口期"累计异常收益率的分析,为投资者分别提供在中美贸易"正面""负面"两种新闻事件冲击下对国际贸易板块进行投资的最佳区间,最大化其超额收益。为投资者在中美贸易摩擦时期对国际贸易板块进行投资时,合理的规避风险、最大化其超额收益,同时提升投资者在负面新闻事件发出时的情绪,减少国际贸易公司市值的进一步缩水。     

基于油价冲击分解的价格传递效应研究

本文通过构建SVAR模型,采用2000年12月至2016年12月的月度数据,将国际油价冲击分解为供给冲击、经济需求冲击以及预防性需求冲击,考察这三种结构性冲击对我国进口价格与国内价格的传递效应及其差异性,在此基础上进一步识别我国通货膨胀的主要来源.结果显示:经济需求冲击与预防性需求冲击带来的国际油价上涨对价格具有正向影响,而供给冲击带来的国际油价上涨对价格的影响方向则不确定;在影响程度上,预防性需求冲击的影响最大,经济需求冲击次之,供给冲击的价格传递作用最小,国际油价冲击对我国通胀的影响主要表现为预期型通胀;此外,在整个商品流通链条中,由于我国市场需求不足以及价格管制等因素,国际油价冲击对我国通胀的影响具有不完全性,这主要表现在国际油价冲击对生产者价格指数的影响最大,而对消费者价格指数的影响则不显著.     

人民币升值对中美贸易的影响分析

2005年7月21日,我国对人民币汇率形成机制进行了改革。汇改后,人民币一直保持缓慢升值之势。本文从中国向美国的出口额、中国从美国的进口额、中美贸易结构和中美双边贸易条件四个角度分析了人民币升值对中美贸易的影响。由于我国对美国出口贸易的特点和美国的出口政策,适度的人民币升值对中美贸易的进出口额影响不大。从长期来看,人民币升值会对我国出口企业形成压力,促使其进行技术创新,从而使中美贸易结构升级。本文结合中美贸易商品的价格弹性、市场竞争状况分析,得出人民币升值可改善我国对美国的价格贸易条件和双要素贸易条件。最后,强调人民币升值必须坚持小幅度、渐进式原则,要积极采取措施,以缓解人民币升值的压力和应对人民币汇率变动的风险。     

从历史数据看货币供给对消费价格与房地产价格的影响——基于货币数量论的分析

本文以货币数量论为理论基础,通过对历史数据的总结以及结构VAR（风险估价）模型的实证分析得出,货币供给对消费价格以及房地产价格的影响较为显著,其影响程度则取决于过多的货币是流向商品市场还是资本市场。在当前货币供给持续处于高位的背景下,消费价格与房地产价格将会此消彼长。     

贸易战对2019年中美外经贸经济影响显现

尽管中美之间的贸易关税战已经偃旗息鼓,但是,从2018年开始的关税调整已经实实在在地影响了中美的外经贸发展,对中美两国外经贸的负面影响正在逐渐显现,已经对中国和美国经济增长、双边货物贸易、利用外资和直接投资等产生了愈来愈大的负面影响,甚至对两国国民经济的发展也产生了一定的影响。衷心希望中美第一阶段的贸易协定得到认真的落实,也十分期盼中美贸易尽快步入正常发展的轨道.     

The Market for New Issues: Impact of Offering Price on Price Support and Underpricing

Previous studies have shown that the pattern of first day returns to initialpublic offerings is consistent with the hypotheses of underpricing and price support. We examine two different periods, 1975–1984 and 1996–2002, and find that in each case the measures of price support and underpricing are substantially affected by the initial public offerings' beginning price. During the period 1975–1984, the mean and standard deviation of returns to the price supported group are nearly always zero regardless of price, whileg the mean of the returns to the underpriced group is smile-shaped: high for low-priced and high-priced stocks but lower for stocks offered at intermediate prices. The patterns are different in the most recent data: the mean and standard deviation of both the price supported and underpriced groups are smile-shaped. For the lowest priced stocks, the measures in the later period mirror those for the 1975–1984 period, but for more expensive stocks the measures are substantially higher. The results apply to the first day returns of both firm commitment and best efforts offerings. Once price is taken into account, other than the difference in the probability of price support, the differences among offering types seem to be of secondary importance in explaining first day returns.

人民币汇率对我国外贸影响的实证研究

对中国三个重要贸易伙伴美国、欧盟和日本的货币的汇率回归分析表明,在人民币对三种货币的汇率与对于三个经济体的贸易差额之间没有显著的相关关系,但是对这一结果的政策含义可以有不同的解读.人民币是否应该升值还可以观察一段时间.
