The Impact of the Volatility of Monetary Policy Shocks

This paper studies the impact of the volatility of monetary policy using a structural vector auroregression (SVAR) model enriched along two dimensions. First, it allows for time‐varying variance of monetary policy shocks via a stochastic volatility specification. Second, it allows a dynamic interaction between the level of the endogenous variables in the VAR and the time‐varying volatility. The analysis establishes that the nominal interest rate, output growth, and inflation fall in reaction to an increase in the volatility of monetary policy. The analysis also develops a dynamic stochastic general equilibrium model enriched with stochastic volatility to monetary policy that generates similar responses and provides a theoretical underpinning of these findings.     

What Is the Importance of Monetary and Fiscal Shocks in Explaining U.S. Macroeconomic Fluctuations?

This paper analyzes the importance of monetary and fiscal policy shocks in explaining U.S. macroeconomic fluctuations, and establishes new stylized facts. The novelty of our empirical analysis is that we jointly consider both monetary and fiscal policy, whereas the existing literature only focuses on either one or the other. Our main findings are twofold: fiscal shocks are relatively more important in explaining medium cycle fluctuations whereas monetary policy shocks are relatively more important in explaining business cycle fluctuations, and failing to recognize that both monetary and fiscal policy simultaneously affect macroeconomic variables might incorrectly attribute the fluctuations to the wrong source.     

The transmission of inflation in a small economy: an empirical analysis of the influence of US monetary disturbances on Canadian inflation, 1962–1980

The paper examines the transmission of inflation in Canada during 1962–1980 using an empirical methodology which is very flexible in determining the direction of casuality and the shape of distributed lag effects. The paper finds that US monetary growth exerted an important effect on Canadian inflation during both fixed and flexible exchange-rate periods. The evidence also shows that Canadian monetary growth has remained linked to US monetary growth under the present flexible exchange-rate regime.     

Real effects of anticipated and unanticipated money: Some problems of estimation and hypothesis testing

The paper addresses two issues that arise in estimation and testing of the real effects of anticipated and unanticipated money. First it is shown that identification of the effects of unanticipated (or unperceived) monetary growth on real output is possible only if the a priori restriction is imposed that monetary growth does not depend on unanticipated (or unperceived) output. Second, the existing empirical work of Barro and others does not allow for three known channels through which money can affect real variables. These are (1) past and present anticipations of future monetary growth (the inflation tax channel), (2) expectations of monetary growth in a given period conditioned at various preceding dates (the Fischer-Phelps-Taylor effect) and (3) past and present revisions in forecasts of future monetary growth. The presence of the first of these would mean that alternative open-loop monetary growth rules have real effects. The presence of the other two implies that monetary feedback rules can have real effects. Omission of the first channel can lead to biased estimates of the effects of past anticipated monetary growth. Potentially serious observational equivalence problems are associated with the other two.     

A quarterly model of unanticipated monetary growth,output and the price level in the U.K. 1963–1978

This paper develops and estimates using quarterly data from 1963 to 1978 a three-equation model of the U.K. economy, in which output is affected only by unanticipated monetary growth whereas the price level is influenced by both anticipated and unanticipated changes in the money supply. Expectations of monetary growth are assumed to be Muth-rational. The model was estimated using efficient procedures and tests of the over-identifying restrictions were favourable to the model specification. In particular, anticipated monetary growth was found to have no significant effect on output.     

The high-frequency response of exchange rates to monetary policy actions and statements

This paper investigates the impact of US monetary policy on the level and volatility of exchange rates using an event study with intraday data for five currencies (the US dollar exchange rate versus the euro, the Canadian dollar, the British pound, the Swiss franc, and the Japanese yen). I construct two indicators of news about monetary policy stemming separately from policy decisions and from balance of risk statements. Estimation results show that both policy decisions and communication have economically large and highly significant effects on the exchange rates, with the surprise component of statements accounting for most of the explainable variation in exchange rate returns in response to monetary policy. This paper also shows that exchange rates tend to absorb FOMC monetary surprises within 30-40 min from the announcement release.     

The integration of the offshore and domestic banking system

The thesis of this article is that offshore banks are branches of the major U.S., British, Swiss, German, Japanese, etc., banks situated in ‘monetary havens’ jurisdictions in which they are subject to minimal regulation, especially to requirements that they must hold non-interest bearing reserves against their deposits. Each bank determines the maximum interest rate to pay on offshore deposits as a function of the maximum interest rate on domestic deposits and the implicit tax on reserve requirements. The more rapid growth of offshore deposits than of domestic deposits during the last several decades reflects two factors — the implicit tax on domestic deposits has increased with the upward movement in interest rates and investor assessment of the risk associated with external deposits has decreased. The effective reserve requirement applicable to each bank is the weighted average of requirements applied to its domestic deposits and to its offshore deposits. Because offshore deposits have grown more rapidly than domestic deposits, the effective reserve requirement has decreased: the fractional reserve multiplier has increased. Because the growth of offshore deposits to domestic deposits appears highly variable, the effectiveness of monetary control has declined.     

货币增长是否导致了通货膨胀?——基于因果关系的动态视角

本文通过构造GF统计量检验了我国2001年以来货币增长与通货膨胀的动态因果关系,并通过设计"格兰杰-F"检验和"格兰杰-F"统计量考察了经济增长在货币增长与通货膨胀传导关系中所扮演的角色。研究发现:货币增长并非总是通货膨胀的格兰杰原因;2008年以后,货币增长逐渐成为影响物价水平的主因,但经济增长是实现这一因果关系的主要途径之一;在经济增速放缓时期,由于货币因素所导致的物价水平上涨能够刺激经济增长。     

The Role of Interbank Markets in Monetary Policy: A Model with Rationing

This paper analyzes the impact of asymmetric information in the interbank market and establishes its crucial role in the microfoundations of the monetary policy transmission mechanism. We show that interbank market imperfections induce an equilibrium with rationing in the credit market. This has two major implications: first, it reconciles the irresponsiveness of business investment to the user cost of capital with the large impact of monetary policy ( magnitude effect ), and second, it shows that banks' liquidity positions condition their reaction to monetary policy ( Kashyap and Stein liquidity effect ).     

Central bank announcements of asset purchases and the impact on global financial and commodity markets

We present evidence on the effects of large-scale asset purchases by the Federal Reserve and the Bank of England since 2008. We show that announcements about these purchases led to lower long-term interest rates and depreciations of the U.S. dollar and the British pound on announcement days, while commodity prices generally declined despite this more stimulative financial environment. We suggest that LSAP announcements likely involved signaling effects about future growth that led investors to downgrade their U.S. growth forecasts lowering long-term US yields, depreciating the value of the U.S. dollar, and triggering a decline in commodity prices. Moreover, our analysis illustrates the importance of controlling for market expectations when assessing these effects. We find that positive U.S. monetary surprises led to declines in commodity prices, even as long-term interest rates fell and the U.S. dollar depreciated. In contrast, on days of negative U.S. monetary surprises, i.e. when markets evidently believed that monetary policy was less stimulatory than expected, long-term yields, the value of the dollar, and commodity prices all tended to increase.     

货币政策和银行风险承担：一种非线性关系

宽松的货币政策会通过估值、收入和现金流机制,追逐收益机制以及中央银行沟通和反应机制等渠道增加银行风险承担,通过风险转移机制降低银行风险承担,从而导致货币政策与银行风险承担之间可能存在复杂的非线性关系。本文使用面板阈值模型,基于我国银行业数据研究了货币政策对银行风险承担的影响,发现我国货币政策对银行风险承担的影响存在门限效应,即货币政策对银行风险承担的影响取决于货币政策基准利率偏离泰勒规则利率的程度。当这种偏离小于门限值时,宽松货币政策会增加银行风险承担;当这种偏离大于门限值时,宽松货币政策会降低银行风险承担。本文研究对更好地理解我国货币政策对银行风险承担及金融稳定的影响有一定参考意义。     

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。     

资产规模、资本状况与商业银行资产组合行为——基于中国银行业面板数据的实证分析

本文立足于我国转型期内的经济金融特征,构造了一个银行资产组合行为的局部均衡模型。在对中国银行业按照资产规模和资本状况进行分类的基础上,本文的实证分析证明了模型的基本含义:由于银行间的异质性,紧缩性货币政策之后商业银行的资产组合行为体现出了截面效应。基于此,本文提出了确立以银行资产组合行为为基础的货币政策决策体系,加强货币政策与监管政策之间的协调等政策建议,以提高货币政策的有效性。     

中国宏观调控工具的选择及效应研究

基于中国的宏观调控政策事实,本文在Gali（1992）基础上构建了包含数量型货币 政策、价格型货币政策和财政政策的SVAR模型,并运用1995年-2017年的宏观数据进行了实证 检验。SVAR模型的实证显示,数量型货币政策对产出和通胀均有正向效应,价格型货币政策 对当前宏观经济增长作用有限,扩张性财政政策对产出和通胀均有快速显著的正向刺激作用。

货币政策与银行风险承担

本文从货币政策影响银行风险承担的作用机理入手,总结了风险定价模型效应、逐利锦标赛效应、思维定势效应和中央银行沟通反馈效应等四条货币政策对银行风险承担影响的渠道,并以2004~2010年中国16家上市银行的数据为样本,采用系统广义矩估计方法实证分析中国货币政策对银行风险承担的影响。实证分析结果表明:我国货币政策与银行风险呈负相关关系,即宽松的货币政策鼓励了银行的风险承担;随着存款利率水平和存款准备金率的降低,银行的风险承担提高;同时中国银行的风险承担与GDP的增长呈正相关关系,即具有显著顺周期特征。     

Stocks,flows, and market equilibrium in neoclassical monetary growth models

The treatment of short-run monetary equilibrium in neoclassical monetary growth theory has been criticized as one of asset market equilibrium that leaves the status of real flows unclear. The paper shows this dichotomy to be the result of a stock-flow confusion. A resolution is attempted on the basis of which it is shown that the output market is in fact continuously equilibrated, and that neoclassical models can be employed for short-run analysis.     

“稳增长”与“防风险”双目标的宏观调控政策抉择

“防风险”和“稳增长”是当前宏观调控的两大政策目标,为此,本文构建一个平衡兼顾双重政策目标的门限理论模型框架,基于反事实方法评估了动态平衡上述两大目标的最优财政货币政策组合。研究表明:(1)2008年以前,财政政策和货币政策都表现出较强的稳增长政策功效,但国际金融危机后,政策取向更倾向于动态平衡“稳增长”与“防风险”目标。(2)财政政策对三部门杠杆的影响呈现显著增强态势,数量型货币政策效果则在经历“增加—下降”周期后趋于稳定,利率政策效果显著而且近年来呈现增强态势,由此表明利率的传导效果正在不断得以强化。(3)从反事实结果看,宏观调控的最优政策搭配抉择取决于政策当局在动态平衡不同目标中的政策取向,特别是,依赖于精准调控“稳增长”与“防风险”目标的偏好强度。     

How does house price influence monetary policy transmission?

The literature has focused on house price growth to explain the inefficiency of monetary policy. From the perspective of substitution, this paper explains the relationship between house prices and monetary policy considering not only house price growth but also house price uncertainty. By constructing a theoretical model including both financial-asset and fixed-asset investment, we find that expansionary monetary policy not only promotes total investment but simultaneously also leads to substitution towards financial assets. However, a rise in house price growth or house price uncertainty will mitigate the substitution effect generated by monetary policy. These propositions are supported by empirical data on China's nonfinancial listed firms from 2009 Q1 to 2018 Q3 and the results are robust to a variety of model specifications and empirical approaches. Our findings imply that real estate regulatory policy should coordinate with monetary policy in maximizing fixed-asset investment.
