Stock Return Predictability and The Role of Monetary Policy

This article examines whether shifts in the stance of monetary policy can account for the observed predictability in excess stock returns. Using long-horizon regressions and short-horizon vector autoregressions, the article concludes that monetary policy variables are significant predictors of future returns, although they cannot fully account for observed stock return predictability. I undertake variance decompositions to investigate how monetary policy affects the individual components of excess returns (risk-free discount rates, risk premia, or cash flows).     

货币政策目标、资产价格波动与最优货币政策

货币政策目标的实现程度是判定货币政策优劣的标准。通过建立中央银行的决策模型,推导出忽略和考虑资产价格的最优货币供应量反应函数,并据此对中国不同货币政策目标下的宏观经济运行进行模拟,以认识货币政策目标对资产价格波动与最优货币政策之间关系的影响,结果表明最优货币政策是否应该对资产价格的波动反应取决于货币政策目标。因此,应充分重视货币政策目标的取向,同时加强对最优货币政策目标确定的研究。     

Learning,Monetary Policy,and Asset Prices

We explore the stability properties of interest rate rules granting an explicit response to stock prices in a New Keynesian DSGE model where the presence of non‐Ricardian households makes stock prices nonredundant for the business cycle. We find that responding to stock prices enlarges the policy space for which the equilibrium is both determinate and E‐stable (learnable). In particular, the Taylor principle ceases to be necessary, and determinacy/E‐stability is granted also by mildly passive policy rules. Our results appear to be more prominent in economies featuring a lower elasticity of substitution across differentiated products and/or more rigid labor markets.     

资产价格膨胀,货币政策转向

近期,货币当局的一系列言论都涉及了一个敏感的话题,即货币政策和资产价格的关系.央行货币政策司司长张晓慧以个人名义公开发表<关于货币政策与资产价格>一文,她认为鉴于当前全球通胀机理所发生的变化,中央银行需要重新思考货币政策如何应对资产价格.此文一出,学术界纷纷揣测未来货币政策的目标是否会出现新的动向,不过监管当局随后的表态则说明,央行虽然非常关注资产价格变化及其成因,特别是宏观层面的原因,但央行目前仍不以资产价格作为货币政策直接调控目标.     

论货币政策与资产泡沫——兼论当前货币政策的动态微调

资产泡沫已经成为现代经济的主要特征之一,将资产价格更多地纳入货币政策的视野,符合现代全球经济变化的趋势,对促进金融经济稳定具有积极的意义.在目前我国实体经济复苏根基未稳的情况下,针对房地产和股市的双泡沫,货币政策微调的目标应该定位于在维持一定程度资产泡沫的同时打消市场对资产价格单边上涨的心理预期,逐步引导资金流向实体经济,通过实体经济的进一步复苏来维持实体经济和虚拟经济的平衡.     

资产价格波动与货币政策选择

2015年以来,我国资产价格剧烈波动是在低通货膨胀环境下出现的资产价格泡沫,由此凸显市场投资投机需求旺盛。经验研究表明,房地产价格波动为短周期行为,具有较强增长刚性;股票价格波动兼具短周期和长周期行为,价格弹性度高。货币流动性及中长期信贷占比的变化趋势能为资产价格泡沫提供有用的预警信息。实证研究表明,资产价格的波动隐含着未来一定时期的通货膨胀和产出的变化信息。针对资产价格属性的区别,货币政策应差异化调控。     

Stock Return Predictability and Asset Pricing Models

This article develops an asset allocation framework that incorporatesprior beliefs about the extent of stock return predictabilityexplained by asset pricing models. We find that when prior beliefsallow even minor deviations from pricing model implications,the resulting asset allocations depart considerably from andsubstantially outperform allocations dictated by either theunderlying models or the sample evidence on return predictability.Under a wide range of beliefs about model pricing abilities,asset allocations based on conditional models outperform theirunconditional counterparts that exclude return predictability.     

货币政策与资产价格的波动

对于中央银行是否应该对资产价格的波动做出反应以及如何做出反应．在学术界仍然存在着激烈的争论。中央银行应否对资产价格的波动做出反应主要依据是看资产价格的波动能否对目标通货膨胀率造成影响，而非直接对任何的资产价格波动都做出反应。对资产价格做出反应形成的货币政策被称为“通货膨胀定标”的货币政策。我国应该根据具体国情进行货币政策的改革导向选择，并积极创造条件推行“通货膨胀定标”的货币政策。     

我国货币政策对利率期限结构影响实证研究

2006年以来我国货币当局频繁使用货币政策调控经济形势,尤其是调整存贷款利率和存款准备金率,而作为基准利率之一的国债利率又是我国货币政策重要的中介指标之一,本文使用事件序列研究方法,分别分析货币政策对交易所市场和银行间市场的收益率曲线的影响。研究发现,交易所市场的期限结构对货币政策反应较为迅速,且紧缩性政策效果不明显,扩张性政策效果显著。而银行间市场反应迟钝,且期限结构的变化与预期存在较大的偏差。     

股票价格、货币政策和宏观经济波动

本文对包含股票价格在内的新凯恩斯模型的结构方程进行估计,分析了股票价格和货币政策与宏观经济波动之间的关系,认为股票价格与宏观经济波动密切相连,货币政策调整可以平滑经济波动。在此基础上,比较了不同的货币政策规则的宏观调控效果,得到的结论是,将股票价格波动纳入货币政策的调控范围会改善货币政策效果,有助于稳定宏观经济。     

资产泡沫与美联储的货币政策

美联储为应对金融危机和经济衰退而采取的各种货币政策措施使其资产负债表快速膨胀,加之今年3月美联储宣布正式实施数量宽松政策,引起各界对未来资产价格是否会再次出现泡沫的讨论。本文认为美联储的货币政策对于上世纪90年代末的科技股泡沫和本世纪初的房地产泡沫的形成及膨胀提供了宽松的货币环境;而本次美联储为应对危机的各项货币政策措施将使利率保持较长期低水平的同时带来基础货币的大量投放,在美国经济结构和增长模式没有发生改变、美元的国际霸权地位没有动摇的背景下,全球资产泡沫可能会再次出现。     

关于资产价格与货币政策问题的一些思考

在全球金融危机的大背景下,货币政策是否应该对资产价格膨胀作出反应引起关注。本文对相关理论进行了归纳,并从通货膨胀机理的角度对资产价格与货币政策的关系进行了探讨,提出了建立和完善更加关注资产价格的货币政策框架的建议。     

REIT Operational Efficiency: Performance,Risk, and Return

Infrequent Housing Adjustment,Limited Participation,and Monetary Policy

This paper asks why monetary contractions have strong effects on the housing market. The paper presents a model with staggered housing adjustment in which monetary policy has real effects in the absence of any rigidity in producer pricing or wages. Limited participation in financial markets leads to a rise in the real mortgage rate following an increase in the nominal short rate. Since households must take on a mortgage to consume housing, the rise in the real interest rate reduces the share of residential investment in output.     

Monetary Shocks and REIT Returns

We investigate the influence of unanticipated changes in US monetary policy on Equity Real Estate Investment Trusts (REIT’s). Although a number of studies have investigated the issue of interest rate changes, the effect of unanticipated changes has not previously been addressed in terms of possible effects on both REIT’s returns and volatility. The results show a strong response in both the first and second moments of REIT returns to unexpected policy rate changes. The results for the impact of the shock on both mean and volatility of returns is consistent with results from studies addressing broader equity markets. However, we find evidence both against behavioral changes in volatility coincident to US monetary policy decisions and asymmetric responses to the monetary policy shock.

中日货币政策比较研究

本文首先回顾了经济起飞阶段、经济平稳阶段和经济衰退阶段等不同经济环境下的日本货币政策,然后对日本货币政策的运行特点和经济绩效进行具体考察,在此基础上,通过中日两国货币政策在货币运行环境、货币传导机制和货币政策绩效等方面异同的比较,提出了借鉴日本货币政策的经验来提升我国货币政策的绩效的启示性对策。     

Monetary Policy and Asset Prices: A Mechanism Design Approach

We investigate the effects of monetary policy on asset prices in economies where assets are traded periodically in bilateral meetings. The trading mechanism is designed to maximize social welfare taking as given the frictions in the environment and monetary policy. We show that asset price “bubbles” emerge in a constrained‐efficient monetary equilibrium only if liquidity is abundant and the first‐best allocation is implementable. In contrast, if liquidity is scarce, assets are priced at their fundamental value in any constrained‐efficient monetary equilibrium, in which case an increase in inflation has no effect on asset prices, but it reduces output and welfare.     

资产价格波动与货币政策调整问题研究

近年来,尤其是在2007年,中国股票和房地产等资产价格快速增长,给宏观调控带来了很大挑战,因此央行在调整货币政策时是否应考虑资产价格的波动,已成为学术界讨论的热点问题。在这种背景下,本文通过对资产价格渠道在货币政策传导中有效性的实证检验显示,货币政策对资产价格有着较大的影响力,然而货币政策通过资产价格渠道影响实体经济效果有限。基于此,本文不主张把资产价格纳入货币政策规则,但是央行在制定货币政策时应关注资产价格的波动。     

资产价格泡沫、货币政策和宏观审慎监管:最新研究进展

由本次全球金融危机引发的资产价格泡沫与货币政策、宏观审慎监管之间关系研究的热潮是对以往货币政策和宏观审慎政策理论的一次深刻反思,将有可能导致理论上的重大突破和政策实践上的重大调整.这是当前全球货币政策理论和实践领域的最前沿、最热门的课题.近期国外机构的研究认为:(1)现有的通货膨胀指标不能全面准确反映货币购买力的变化,必然导致资产价格泡沫周期;(2)可以从经济金融变量中提取资产价格泡沫形成的早期预警信息,这为采用"逆风而动"的货币政策策略创造了条件;(3)现行的货币政策框架需要调整,以抑制资产价格泡沫的形成;(4)调整后的货币政策策略仍不足以应对金融失衡,需改进宏观审慎监管,与货币政策一起共同应对金融失衡.国外的研究对我国的政策实践具有借鉴意义.     

REIT Short Sales and Return Predictability

We examine REIT short sale transactions and show REITs are shorted less frequently than non-REITs. Results also show short sellers are less able to predict negative future returns for REITs, relative to non-REITs, which is consistent with increased pricing efficiency for REITs and suggests REIT assets are more transparent. In a broader context, these results suggest differences in transparency across asset types influence the effectiveness of short selling. Results showing REIT short sellers are contrarian imply traders target REITs that are performing well instead of underperforming REITs, suggesting restrictions on REIT short sales should be re-evaluated.
