Information, learning, and the stability of fiat money

We analyze the stability of monetary regimes in an economy where fiat money is endogenously created by the government, information about its value is imperfect, and learning is decentralized. We show that monetary stability depends crucially on the speed of information transmission in the economy. Our model generates a dynamic on the acceptability of fiat money that resembles historical accounts of the rise and eventual collapse of overissued paper money. It also provides an explanation of the fact that, despite its obvious advantages, the widespread use of fiat money is only a recent development.     

含有货币变量的宏观经济模型简析

现代宏观经济分析中,一般均衡框架是必不可少的重要因素。但是传统的一般均衡模型通常缺乏实际经济运行过程中一种不可或缺的因素———货币。所以,在传统的均衡或者非均衡模型中引入货币变量,并且判断和分析货币变量及货币政策的作用机制,就成为了货币经济学面对的一个挑战。通过对Tobin货币模型、货币内在效用模型和现金在先模型的分析表明,货币在经济中应该起到的确切作用和所承担的功能,尚未完全被清楚地认识,这为货币政策传导机制和作用机制过程中存在的不确定性留有大量理论探索的余地。     

居民风险偏好与中国货币政策的宏观经济效应——基于DSGE模型的数量分析

当前,我国宏观经济形势复杂多变,货币政策实施效果的影响因素随之呈现多样化特征。在此背景下,本文试图以风险偏好为研究视角,对我国居民风险偏好水平变动与货币政策宏观经济效应之间的关系进行分析。本文以标准新凯恩斯模型为基础,构造符合我国宏观经济现实特征的DSGE(动态随机一般均衡)模型,并对转型时期的最优混合型货币政策规则进行研究;为进一步强调货币在中国宏观经济波动中所扮演的重要角色,模型中引入消费和实际货币余额不可分的跨期效用函数形式。研究结果表明:(1)包含名义货币增长的混合型泰勒规则拟合我国转型时期的货币政策规则效果最佳,因此货币供应量仍是重要的政策工具;(2)与可分性模型相比,不可分模型拟合我国宏观经济现实特征的效果更优。在不可分效用函数下,与货币供应量相关的实际货币余额将影响经济的产出缺口和通货膨胀,使得居民风险偏好成为决定货币政策效果的重要因素。具体而言,当居民风险偏好水平上升时,货币政策对我国宏观经济波动的影响随之增强。因此,在选择货币政策实施时点上,应充分考虑市场中的风险偏好情况,从而更好地发挥货币政策调控宏观经济的职能。

Modelling credit in the transmission mechanism of the United Kingdom

Studies have focused heavily on money in the transmission mechanism of monetary policy. In this article we explore the empirical importance of credit. The paper provides a framework in which to analyse the balance sheets of, and financial flows between, different sectors of the UK economy, and an econometric model of the interactions between non-financial firms, households and credit offered by banks and non-bank financial intermediaries. The paper also provides a dynamic structural model of bank and building society credit, money and decisions to consume and invest and then adds credit from non-bank financial intermediaries. Our bottom line is that credit is an important part of the transmission process of UK monetary policy.     

Monetary disequilibria and the euro/dollar exchange rate

Although stable money demand functions are crucial for the monetary model of the exchange rate, empirical research on exchange rates and money demand is more or less disconnected. This paper tries to fill the gap for the euro/dollar exchange rate. We investigate whether monetary disequilibria provided by the empirical literature on US and European money demand functions contain useful information about exchange rate movements. Our results suggest that the empirical performance of the monetary exchange rate model improves when insights from the money demand literature are explicitly taken into account.     

Habit formation and the persistence of monetary shocks

The dynamic effects and relative importance of monetary shocks in the US business cycle are studied using a sticky-price dynamic stochastic general equilibrium model with habit formation and capital adjustment costs. The model is estimated via maximum likelihood using data on output, real money balances, and the nominal interest rate. Econometric results indicate that the model has a strong internal propagation mechanism that can explain the persistent and hump-shaped response of US output and consumption to monetary shocks.     

混频数据信息下的时变货币政策传导行为研究——基于混频TVP-FAVAR模型

现实经济环境中,货币政策操作受到金融市场及宏观经济信息的共同影响.如何基于混频大数据信息分析货币政策行为机制是需解决的现实问题.为此,本文提出一种混频时变参数因子增广向量自回归(MF-TVP-FAVAR)模型.基于宏观经济及金融市场等多维度混频数据信息的实证结果表明:首先,MF-TVP-FAVAR模型在宏观金融混频数据中提取的金融形势指数(FCI)能较好地表征宏观经济先行趋势,为货币政策的制定提供前瞻性信息.其次,混频TVP-FAVAR模型可以捕捉价格型和数量型货币政策传导的高频时变特征.与货币供应量相比,利率传导对产出的影响具有滞后性.利率传导随着利率市场化改革愈发畅通,而信贷传导机制因财政政策搭配等问题日渐受阻.再次,货币政策传导效果受到经济周期影响,无论产出效应还是价格效应,经济上行时期,货币政策传导机制都比经济衰退时期更加通畅.价格型和数量型传导机制在经济下行时的作用效果均会减弱,但数量型货币政策更易受到经济周期的影响.最后,货币政策对FCI的冲击响应具有时变性,说明金融市场信息冲击对我国货币政策调控具有结构性的动态影响.货币当局制定尤其是微调货币政策时应及时评估金融市场信息冲击的影响.     

麦克林模型视角下中国货币政策探究

温家宝总理在2011年政府工作报告中提出,要把稳定物价总水平作为宏观调控的首要任务,而保持物价稳定需要以合理的货币供给为基础。本文在麦克林模型视角下。探索货币供给量对物价的动态影响方式、途径,提出货币可以作为变量来对物价水平进行预测．在此基础上运用自回归模型证明货币政策对整个社会的名义产出产生巨大冲击。     

Safe Assets as Commodity Money

This paper presents a model in which safe assets are systemic because they are the medium of exchange in risky assets. It connects the literature from banking and finance on safe assets to the monetary literature on alternative monetary systems involving commodity money, interest bearing money, and private money creation. Because safe assets have intrinsic value, changes in their supply lead to changes in market efficiency. Additionally, because safe assets are costly to produce, there is overproduction of safe assets relative to the social optimum. When the model is calibrated to plausible liquidity premiums the resulting inefficiencies are not large.     

中国系统性金融风险度量与货币政策影响机制分析

本文从宏观总体层面构建中国系统性金融风险指数,以SV-TVP-VAR模型分析国内外货币政策对系统性金融风险的影响。结果表明,2001-2018年中国系统性金融风险基本维持在较为稳定的状态并呈现下降趋势;国内货币政策对系统性金融风险产生重要影响,数量型货币供给量的冲击效应更加直接;国外货币政策在金融危机期间对系统性金融风险的冲击较强但冲击在不断减弱。     

我国广义货币供应量M2的回归模型与预测

货币供应量是货币政策工具重要的中介变量。该文通过分解我国货币供应量的诸多宏观影响因素,尝试建立一个较为完整的货币供应量多变量回归模型,揭示宏观经济变量对货币供应量的影响程度,并运用该模型对货币供应量的短期变化进行预测,以期为把握宏观经济形势、理解货币政策变化及预判金融市场走势提供参考依据。检验结果表明,该模型对货币供应量的预测比较符合实际情况。     

Money,Bonds, and the Liquidity Trap

This paper examines a search model of money and public bonds in which coordination frictions lead to multiple, Pareto ranked equilibria. Whether money and bonds are substitutes or complements, is not a primitive of the economy, but an equilibrium outcome. There exists an equilibrium resembling a liquidity trap, in which money and bonds are perfect substitutes, interest rates are zero, and monetary policy is ineffective; and a superior equilibrium in which money and bonds are complements, interest rates are positive and monetary policy has a liquidity effect. On this view, the liquidity trap is a belief-driven phenomenon.     

电子货币对存款准备金制度的冲击效应研究

本文以电子货币为视角,将电子货币引入存款准备金制度的理论分析框架,在理论分析及对传统货币模型修正的基础上,选择电子货币与存款准备金政策相关的变量,建立数量经济模型。通过统计检验发现：电子货币放大了货币乘数,并使货币乘数变得不稳定,从而加大了中央银行通过存款准备金政策影响货币乘数来调节商业银行信用创造能力的难度,削弱了存款准备金政策的效率。     

开放经济下我国货币需求长期稳定性研究

本文利用我国1996—2011年的月度数据,分别使用Johansen协整检验与Engle—Granger两步法,对传统货币需求模型、开放条件下的货币需求模型以及引入制度因素的货币需求模型进行实证检验,研究货币需求的长期稳定性及各因素对货币需求的影响,建立货币需求模型,对于提高我国货币政策的调控效率具有重要意义。     

Monetary policy and distribution

A segmented markets model of monetary policy is constructed, in which a novel feature is goods market segmentation, and its relationship to conventional asset market segmentation. The implications of the model for the response of prices, interest rates, consumption, labor supply, and output to monetary policy are determined. As well, optimal monetary policy is studied, as are the costs of inflation. The model features persistent nonneutralities of money, relative price effects of increases in the money supply, persistent liquidity effects, and a negative Fisher effect from a money supply increase. A Friedman rule is in general suboptimal.     

基于ARINA模型的我国广义货币供应量变动规律研究

货币供给对我国货币政策运行乃至整个宏观经济调控具有重要意义,广义货币供应量的规模及其变化趋势直接影响到中央银行货币政策的执行效果。本文运用ARIMA模型,对1996年1月至2012年1月期间我国广义货币供应量的变动规律进行研究,并运用模型对给定样本期内的M2值进行了预测,结果表明本文建立的ARIMA模型具有良好的预测精度。     

我国货币政策对股票市场收益率影响的实证研究

为检验我国货币政策对股票市场的有效性,本文在经典理论的基础上,运用协整检验、格兰杰因果检验、VECM检验方法,对货币政策与股票市场收益率关系进行实证分析。研究结果表明：货币供应量增长率与股票市场收益率呈正相关关系,但长期内影响效果不显著;利率的调整在短期内对股票收益率的影响较为显著,在长期内则表现为平稳,两者关系符合一般金融理论;进一步地,采用虚拟变量回归模型,分析了货币政策环境变化对收益率大小的影响。笔者根据我国的国情,分析这种传导效应的结果,做出了相应的判断,并对如何解决货币政策对股票市场传导中存在的问题提出了自己的看法。     

Demand and supply functions for money in Canada: Some further evidence

The demand and supply functions for money in Canada are estimated in a simultaneous-equation model format in which the supply of money is considered endogenous. The results indicate that the important determinants of the demand for money are income, short-term interest rate and lagged real cash balance variables. Wealth is an unimportant explanatory variable in money demand thus rejecting the hypothesis that an increase in outside wealth increases the demand for money. The monetary base and cash reserve ratio are important explanatory variables in the money supply function and play a direct role in monetary control.
