货币政策冲击对股票市场流动性的影响——基于Markov区制转换VAR模型的实证研究

本文首先对货币政策影响股市流动性的机理进行分析,在此基础上,尝试构建了一个新的股票市场流动性指标,通过引入MS-VAR模型,考察了货币政策在不同区制下对股市流动性的动态影响。基于MSIH(3)-VAR(4)模型和累积脉冲响应的结果表明,货币政策扩张有助于提高市场流动性,货币政策收紧,会导致市场流动性降低。但在不同区制下,影响程度存在显著差异,当股市处于膨胀期时,货币政策冲击对市场流动性的影响比股市处于低迷期时表现得更加明显。同时,股市收益率和股市波动率对股市流动性也存在显著影响。     

中国货币政策对股票市场影响的再考察

本文运用DAG方法、VAR模型和马尔科夫转换模型考察了货币政策对股市价格水平的影响,结果表明中短期内货币政策对股票市场价格水平存在影响显著,并表现出较强的非对称效应。股市低迷期的紧缩性货币政策会进一步降低股市收益率,减小股市从熊市转入牛市的概率;相反,股市繁荣期的紧缩性货币政策将增加股市从牛市转入熊市的概率。     

UK Stock Returns and the Impact of Domestic Monetary Policy Shocks

Abstract:  We investigate the influence of changes in UK monetary policy on UK stock returns and the possible reasons behind such a response. Firstly, we conduct an event study to assess the impact of unexpected changes in monetary policy on aggregate and sectoral stock returns. The decomposition of unexpected changes in the policy rate is based on futures markets data. Secondly, using a variance decomposition in the spirit of Campbell (1991) we attempt to identity the channels behind the response of stock returns to monetary policy surprises. The variance decomposition results indicate that the monetary policy shock leads to a persistent negative response in terms of future excess returns for a number of sectors.     

政策性冲击、货币政策操作目标：基于准备金市场模型的实证研究

对于我国货币政策操作目标,并没有一个明确的说法。为了对相对稳定、有效的货币政策操作目标进行实证判断,本文建立了宏观经济变量和准备金市场变量的结构性向量自回归模型(SVAR),通过识别假设把SVAR模型转化为包含政策变量和非政策变量新息(innovation)的关于政策变量的半结构性向量自回归模型(Semi-SVAR)。通过准备金市场模型,界定了可观察残差项与结构扰动项之间的黑箱,对我国货币政策操作目标进行识别。实证结果显示,1998年以来,我国相对稳定、有效的货币政策操作目标是准备金总额,也可以说是基础货币,并不是超额准备金和货币市场利率。识别的政策冲击反映了货币政策调控事件对货币供求的冲击,与我国货币政策的操作实际很吻合。     

Federal Reserve Monetary Policy and Industry Stock Returns

Recent studies identify stock return patterns associated with changes in Federal Reserve monetary policy. We find that these return patterns prevail across sixteen industry stock indices. However, significant cross-industry variation exists as the apparel industry exhibits mean annual returns that are 50% higher under an expansive Fed policy than under a restrictive policy, while the same return difference for the oil industry is only 20%. This cross-industry variation suggests that monetary conditions may be used by investors to estimate different expected returns across industries. Furthermore, the findings support the view that monetary considerations should be considered in ex ante asset pricing models such as the CAPM.     

我国货币政策变动对股票市场短期调控效应的实证分析

货币政策变动会对股市造成冲击。本文利用GARCH模型,运用事件研究方法研究利率、存款准备金率调整对股票市场的短期影响。通过实证分析,表明货币政策调整会对股票收益产生影响,但每次政策调整宣告对股票市场的影响程度、作用时间甚至影响方向都有所不同。这种即期影响取决于调整时经济运行的总体状况、股指相对位置、股市盘整的时间等影响因素,同时也取决于市场对政策调整的预期。     

The Impact of Monetary and Fiscal Policy Shocks on Stock Markets: Evidence from China

We study the impact of Chinese monetary and fiscal policy shocks and the interaction of the two policies on stock markets. We find that, first, when we focus on the contemporaneous correlation, Chinese fiscal policy has significant, negative contemporaneous relationships with stock market performance, while monetary policy’s impact on stock market performance varies, depending on the fiscal policy. Second, with respect to the lagged variables, Chinese monetary and fiscal policy both have a significant and direct positive effect on stock market performance. Meanwhile, interaction between the two policies plays an extremely important role in explaining the development of stock markets.     

我国证券市场税收政策浅析

我国现行以证券交易印花税为主体的证券税制,在组织财政收入、调节证券市场、抑制过度投机等方面发挥了一定作用,但还存在一些不足之处。建议:进一步调整证券交易印花税的征收办法;建立一套系统、健全的证券税制;消除对公司和股东个人股、红利的重复征税;统一上市公司的企业所得税政策。     

利率政策对货币市场的“非对称性”传导

运用事件研究法,检验了2007~2010年在通胀和危机背景下中国10次调整存贷款基准利率对同业拆借市场利率的影响。研究发现,利率调整对市场利率存在非对称性传导效应,主要表现在,降息会使市场利率下降,加息却对短期市场利率产生显著的负向效应。究其原因在于,中国利率市场化程度不高和货币超经济发行导致银行体系内流动性过剩。     

Stock Market Reaction to the Appointment of Outside Directors

This paper examines the UK stock market's reaction to the appointment of outside (non‐executive) board members. Tests conducted using a sample of 714 appointments reported by EXTEL between 1 July, 1993 and 31 December, 1996, indicate a strong interaction between appointee characteristics and the magnitude of the agency problem: the share price reaction to outside director appointments is significantly more favourable when board ownership is low and the appointee possesses strong ex ante monitoring incentives. In contrast, the appointment of independent and manager‐affiliated outside directors does not appear to benefit shareholders on average, even in the presence of serious agency problems.     

股票价格具有货币政策指示器功能吗——来自中国1997～2006年的经验证据

本文运用VAR模型考察了以股票价格为代表的金融资产价格对我国通货膨胀的影响。实证分析表明,我国股票价格的变动对产出缺口存在一定的正向影响,但是这种影响不太稳定,说明我国股票价格通过总需求渠道对未来通货膨胀产生的影响比较微弱。同时,我国股票价格的变动能引起未来CPI和WPI的同向变化,尤其与CPI的关系非常稳定,说明股票价格在一定程度上包含了我国未来通货膨胀的信息。因此,我国股票价格可以作为一个帮助判断未来经济走势和通货膨胀变动趋势的货币政策指示器。     

我国股票市场的财富效应分析

股市可以形成一定的虚拟财富效应,对刺激有效需求能产生正效应。而股市的实际财富效应取决于股市行情上涨对企业投资的传导,这一点又受制于股票市场规模、股市上涨持续的时间以及市场的有效性。     

Effectiveness and Market Reaction to the Stock Exchange's Inquiry in Australia

Abstract:  This paper examines a unique stock market monitoring program used by the Australian Stock Exchange (ASX) . When the ASX observes unusual share price or trading volume changes of a listed company, it sends a letter demanding an explanation. Companies need to respond publicly to several stylized questions. Such public communications between the stock exchange and listed companies contain information. This paper documents how companies respond to the ASX inquiry and how the market reacts to the replies. It is found that some companies do release new information to the market when asked. After the firm's reply is posted, the average trading volume and the bid-ask spread are reduced, and in most cases, the share price is also stabilized with the following two exceptions: (1) The price will continue to rally on average if the company releases only partial information when questioned after a significant price jump; (2) The downward price trend will be reversed if the company states that no new information could explain the decline. Furthermore, there are statistically significant, positive abnormal returns for the first five trading days, which are not conditional upon the replies firms give to the ASX inquiries.     

财政货币政策和我国股市关联性:基于脉冲响应函数和方差分解的对比检验

财政货币政策和股市关联性模型表明,宏观经济政策和股市可能存在强相关性。基于我国时序数据的脉冲响应函数检验结果显示,财政货币政策对股市作用存在阶段性并有着非中性和非对称性特征,即无论个体对政策冲击是否存在有效预期,政策变化对股市都将存在冲击效应。但二者对股市冲击持续时间有较大差异,财政政策冲击往往只存在短期效应,而货币政策冲击对股市长期波动却有显著影响。其中方差检验得出,财政政策对我国股市影响力相对更小。     

盈余持续性、审计师类型对盈余持续性的影响及资本市场反应

以我国2002~2008年期间A股上市公司为研究对象,延续Sloan的方法,利用mishkin检验来考察公司盈余持续性、审计师类型对盈余持续性的影响及股票市场反应。发现公司盈余中应计成分持续性低于现金流量成分;四大审计客户的盈余持续性要高于非四大审计的客户;与公司盈余中现金流量成分相比,四大审计师更显著提高公司盈余中应计成分的持续性;股票价格中所包含的公司盈余预期不能反映公司盈余中应计成分和现金流量成分持续性的差别;股票价格中包含的盈余预期可以总体上反映四大与非四大审计师对公司盈余持续性影响的差异,但股票价格中包含的盈余预期不能反映四大与非四大审计师对公司盈余中应计成分和现金流量成分持续性影响的不同,市场符合＂幼稚投资者＂假说。     

The Response of Equity Prices to Movements in Long‐Term Interest Rates Associated with Monetary Policy Statements: Before and After the Zero Lower Bound

Monetary policy actions since 2008 have influenced long‐term interest rates through forward guidance and quantitative easing. I propose a strategy to identify the comovement between interest rate and equity price movements induced by monetary policy when an observable representing policy changes is not available. A decline in long‐term interest rates induced by monetary policy statements has a larger positive effect on equity prices prior to 2009 than in the subsequent period. This change appears to reflect the impact of the zero lower bound on short‐term interest rates.     

Effects of Monetary Policy Coordination on Small Open Economies

This paper proposes an innovative approach for analyzing the influence of external shocks on small open economies. This approach incorporates the role of large-country monetary policy coordination in influencing shocks and provides an empirical tool to analyze them. In the face of recent fluctuations in commodity prices, this new tool makes it possible to evaluate the influence on small countries of large-country policy coordination in response to these shocks. Based on an analysis of data from Mexico, such policies are found to provide better results for Mexico when Mexico's trade partners coordinated their responses.     

市场分割状态下红筹股回归A股的经济影响

市场分割其实是一种普遍现象。中国A股市场存在一定的泡沫,市场的大起大落以及可供上市的潜在资源相对匮乏,使得红筹股回归成为稳定市场的选择之一。通过对红筹股回归产生的经济效应的分析表明:红筹股回归将增加投资者的投资品种,有助于提升A股投资者的福利水平;由于A股市场普遍溢价于H股市场,红筹股回归的IPO定价可能会高于其原红筹股价格,因而可能存在财富从A股投资者向红筹股投资者转移的现象。     

资本市场开放、本币升值与居民资产结构调整——分析中国股市上涨的三重视角

理论界和实务界普遍认为流动性过剩是导致股市、房市价格上涨的重要原因。自2006年下半年以来,央行接连实施紧缩性货币政策,但都未影响到股市和房市的价格上涨势头。论文从资本市场开放、人民币升值与居民资产结构调整三个角度对我国股市近期的上涨进行理论分析,认为我国资本市场对内对外的逐步开放、人民币缓慢升值与居民资产结构调整是我国股市近期上升的主要原因,并指出股市上涨的流动性过剩假说存在认识误区,新形势下紧缩性货币政策调控股市存在困难。     

股指期货与现货市场的关系研究

本文从市场结构、交易执行效率和市场信息传播三个方面,由浅入深地展开了期现货市场关系的梳理和分析。股指期货市场的出现,一是使得原本现货市场单轨运行的市场结构变为了期现货市场双轨运行的新结构,增加了市场稳定性;二是依托期货交易方式的独特机制,大大提高了交易执行效率;三是期货价格也因此包含了更多内容,促进了市场信息的传播与扩散。同时,股指期货的独特设计使得其非常适合在危机条件下充分发挥功能,是一个重要的风险管理工具,已经成为现代资本市场的重要组成部分和基础性的内在稳定机制。
