货币乘数存在吗——基于我国银行业资产负债数据的信贷传导机制有效性分析

商业银行以同业业务为主的非存款负债以及影子银行体系的发展大大弱化了货币乘数论的有效性,货币供给内生性增强。本文从理论及实证两个方面研究货币乘数论与银行信贷传导机制的有效性。对于央行能否影响商业银行贷款规模这一点,无论是理论分析还是实证检验的论据都不充分。实证研究表明：由于同业负债、理财业务以及出售持有债券获得流动性支持等外部融资渠道的存在,商业银行贷款并不一定受到存款约束,导致传统的货币乘数论失效。在法定准备金率这一数量型货币政策工具有效性降低的前提下,我国货币政策对于宏观经济的影响具有更大的不确定性,央行只有对商业银行等主体的放贷行为和货币创造能力实施有效控制,货币政策才能达到预期效果。     

美联储货币政策对中国货币政策的溢出效应研究

文章主要研究了美国货币政策对中国货币政策的溢出效应,理论部分分析了在开放经济条件下两国模型关于货币政策跨国传输等相关问题。货币供给分为国内供给和外部输入,通过中央银行资产负债表中资产负债的变化可以分析外部货币的输入影响到基础货币的被动投放,在流通过程中由于乘数效应影响了货币供给量。外部货币的输入影响央行调控独立性的发挥,外部货币的输入容易形成对国内货币市场和产品市场某种程度的冲击,央行货币政策调控的难度增加。经验分析发现,美元输入对中国货币政策存在溢出效应,影响到中国的基础货币投放,影响到中国的货币政策的独立性以及执行的效果。     

从金融传导领域分析我国的货币政策传导机制

中央银行的货币政策引起实际经济变量的改变是通过货币政策传导机制实现的。而货币政策的传导机制包括金融传导领域和经济传导领域。其中金融传导是中央银行与金融中介相互影响和相互作用的过程。文章着重通过对金融传导领域中的执行主体、传导中介、市场基础和调节杠杆进行分析,来研究我国的货币政策传导机制。     

The liquidity effect in a flexible-price monetary model

This paper examines the impact of macroeconomic policy shocksin a flexible-price dynamic stochastic general equilibrium (DSGE)model with money. Rather than adopting a money supply rule,monetary policy is modelled as a central bank using a simpleinterest rate rule (Taylor rule). Without assuming price stickinessor frictions in financial markets, this model is found to accountfor liquidity effects, generate higher persistence in outputand inflation, and capture the positive unconditional cross-correlationsrelating inflation and output.     

中国货币政策的福利损失与政策规则选择——基于新凯恩斯DSGE模型的分析

本文在新凯恩斯主义DSGE模型框架下,运用福利损失函数和脉冲响应方法研究我国最优货币政策规则选择的问题。研究结果表明,货币供应量规则相对于利率规则,使外生冲击对产出和通货膨胀的影响更持久,造成更大的福利损失,因此中央银行的货币政策规则应该逐步从货币供应量规则转向利率规则;在一定条件下,前瞻型利率规则、后顾型利率规则和泰勒规则所造成的福利损失相差不大,从便利的角度出发,中央银行应该选择后顾型利率规则。     

DYNAMIC EFFECTS OF MONETARY POLICY SHOCKS IN MALAWI

This paper sets out to investigate the process through which monetary policy affects economic activity in Malawi. Using innovation accounting in a structural vector autoregressive model, it is established that monetary authorities in Malawi employ hybrid operating procedures and pursue both price stability and high growth and employment objectives. Two operating targets of monetary policy are identified, viz., bank rate and reserve money, and it is demonstrated that the former is a more effective measure of monetary policy than the latter. The study also illustrates that bank lending, exchange rates and aggregate money supply contain important additional information in the transmission process of monetary policy shocks in Malawi. Furthermore, it is shown that the floatation of the Malawi Kwacha in February 1994 had considerable effects on the country's monetary transmission process. In the post‐1994 period, the role of exchange rates became more conspicuous than before although its impact was weakened, and the importance of aggregate money supply and bank lending in transmitting monetary policy impulses was enhanced. Overall, the monetary transmission process evolved from a weak, blurred process to a somewhat strong, less ambiguous mechanism.     

紧缩性货币政策下城市商业银行营销策略

受国内外经济环境共同影响,我国央行将在较长的时间内实行从紧的货币政策,它对城市商业银行的基础货币环境、资金运用、信贷结构以及收入的影响是双重的。城市商业银行应该积极应对,运用差异化营销、关系营销等策略,通过树立品牌效应,积极推进金融产品创新和高级人才培养,消除紧缩性货币政策带来的负面效应。     

A Descriptive Model of Banking and Aggregate Demand

We integrate a banking sector into an accessible macroeconomic framework, which then provides new insights on developments around the Global Financial Crisis. The analysis shows that growth of banking sector money supply may help explain the secular decline in long-term interest rates before the crisis. A new bank funding channel of monetary transmission clarifies why increases in central bank policy rates could not reverse this trend. Our analysis highlights the distinction between the zero lower bound and the liquidity trap, and shows that bank recapitalizations can be more effective than fiscal expansions in restoring aggregate demand after a banking crisis.     

我国央行票据冲销操作的实证研究

随着我国外汇储备的激增,近几年,央行票据已经成为中央银行进行冲销操作、回收基础货币最重要的手段。通过运用VAR模型对央行票据冲销操作进行实证检验,研究表明:央行票据的货币冲销效果在短期内是非中性的,它通过影响基础货币和货币市场利率作用于货币供给量;长期内央行票据冲销操作对货币供给量的影响趋于中性,不具有可持续性。     

后金融危机时代我国货币政策工具的优化

货币政策是我国宏观经济调控的重要途径之一,在特定时期内制定实施合适的货币政策能够促进经济发展目标的实现。在以转变经济发展方式、优化经济结构为目标的后金融危机时代,货币政策的制定不仅要考虑对经济总量的调控,更要兼顾经济结构的调控。本文旨在对当前我国央行货币政策工具的实施情况进行归纳,以期发现新时期在兼顾总量与结构调控的背景下当前货币政策工具的不足,并提出优化货币政策工具的建议。     

分析中国货币政策的有效性

我国货币政策的最终目标是稳定币值,促进经济稳定增长。中央银行是通过货币政策工具控制和调节中介目标———货币供应量来实现这个最终目标的。本文通过探讨货币是中性还是非中性,货币供应量是内生还是外生,我国货币政策的传导机制是否畅通这三个问题,最终得出了我国货币政策     

Monetary theory and monetary policy a central banker's view

Summary In this article attention is paid to monetary theory, the relationship between the instruments of monetary policy and other important macro-economic policy instruments, and finally to the real possibilities of pursuing an effective monetary policy. The conclusion from the theoretical analysis is that the total money supply must be considered one of the most important macro-economic policy instruments. An excessive supply of money will sooner or later lead to inflation, to the debasement of money. Therefore the volume of money should be controlled. The use and effectiveness of monetary policy should always be seen in the context of other policy instruments, especially fiscal policy and, under circumstances, wage- and price policy. The possibilities to pursue an effective monetary policy are not unlimited. The effectiveness of such a policy can,e.g., be hampered by external factors. It is vital for a central bank to have the widest possible range of instruments at its disposal.     

Designing a central bank: Social player,monetary agent,or banking agent?

This paper reviews recent advances on the role of the central bank in the money supply process and its effects on inflation. The literature is presented according to a three-stage process, with the central bank acting first as social player, then as monetary agent, and finally as a combined monetary and banking agent.     

影子银行对货币政策的影响——基于内生货币理论视角

影子银行的迅速发展使其成为我国金融体系的重要组成部分,由于其具有一些与传统银行类似的功能,继而对我国货币政策调控的有效性提出了挑战;后凯恩斯货币理论认为货币本质上属于一种债权-债务关系,是非中性的交易媒介,而央行是否能够有效的控制货币供应量呢?本文基于内生货币理论的视角,重新诠释影子银行对我国货币政策的影响,以期对货币政策的制定提供有益借鉴。     

Monetary Aggregates Targeting,Inflation Targeting and Inflation Stabilization in Ghana

The central bank of Ghana (BoG) has operated monetary aggregates targeting and inflation targeting since the 1980s, to ensure enhanced output growth, low unemployment and stable, low inflation. Under inflation targeting, the inflation rate averaged 13.26 per cent per annum between 2007 and 2015, compared with 29.22 per cent per annum under monetary aggregates targeting. The relatively lower inflation rates notwithstanding, an average inflation rate of 13.2 per cent per annum is far above the medium‐term target of 8 per cent. This paper has examined the effectiveness of monetary aggregates targeting and inflation targeting in keeping inflation at moderate levels. The autoregressive distributed lag (ARDL) model was applied to the data covering the period 1970–2015. The results show that monetary targeting has steered inflation to moderate levels only in the short run while inflation targeting has maintained low inflation rates in both short run and long run. But neither regime has kept inflation at stable levels and within the target band, due to the sluggish transmission of broad money supply and prime rate changes to inflation. We implore the monetary authorities to strengthen the institutional setup for steering short‐term interest rates in Ghana. They should also enhance the BoG Act 2002 (Act 612), to develop secondary anchors and rules around output, money supply and fiscal deficit. Finally, the monetary policy committee should monetary policy credibility and transparency through strengthening its communication framework.     

Implications of a negatively sloped LM curve

Conclusion This paper has shown that the LM curve could be downward sloped if the rate of interest on money (specifically liquid deposits) is sufficiently flexible. If so, the momentary equilibrium could be unstable, especially if the LM curve is far from the vertical (i.e., if the interest rate on money is very flexible). Prospects for instability are enhanced if output adjusts slowly or if the central bank varies the money supply strongly over time in response to the general interest rate. If stability obtains with a downward sloped LM curve, fiscal policy has an unconventional direction of effect on income. Three policy implications follow directly. (1) The rate of interest on deposits which are part of the money supply used as the central bank control tool, should not be allowed to be too flexible (to avoid instability). (2) If the monetary deposit rate is quite flexible, the central bank should not have the money supply react too strongly to the general interest rate—i.e., should not come too close to a pure interest rate policy (again, to avoid instability). (3) If the monetary deposit rate is very flexible, fiscal policy should be used with caution (due to the unconventional direction of effect in the event LM is downward sloped).     

Is There a Bank Lending Channel in Southern African Banking Systems?

Abstract: Macroeconomic models currently used by policymakers generally assume that the functioning of financial markets can be fully summarized by financial prices, because the Modigliani and Miller (1958) theorem holds. However, the assumption that this theorem holds is questionable. This paper argues that there are frictions in the market which traditional models based on the Modigliani and Miller theorem fail to take into account in explaining how monetary policy and other shocks are transmitted to the economy and points to new directions. A comprehensive macroeconomic model should incorporate financial market interactions to enhance the understanding of the transmission mechanisms of monetary policy and other shocks. If market dynamics are not taken into account, macroeconomic models used by policymakers may point to wrong policy choices. Motivated by the lack of assessment of the recently launched financial reforms, deregulation, consolidations, financial innovations and joint payment systems, the paper assesses the process of monetary transmission mechanism by investigating evidence of a bank lending channel in SADC during the period 1990–2006 using data from the banking sector. Data from a panel of banks is used to identify shifts in the loan supply curve in response to changes in monetary policy using a vector autoregression (VAR) model. Although the results are mixed the paper generally reports the existence of a bank‐lending channel in all SADC countries in the sample. The take‐off point for monetary policy effects differs from one country to another.     

Monetary Policy Implementation in Japan: What They Say versus What They Do

Since the 1970s, many central banks – including the Bank of England, the Bank of France, the Bank of Korea and the Bank of Japan – have announced that they have ceased direct credit controls. Researchers have tended to accept 'what they say', without gathering empirical evidence on 'what they do'. The Bank of Japan announced that it was abandoning direct credit controls in 1982. Since then, the monetary policy literature on Japan has focussed on formal policy tools, such as interest rates. This paper presents empirical research on the actual implementation of monetary policy by the Japanese central bank. The emphasis is on the period in the mid- to late-1980s when monetary policy was stimulatory and real-estate-related lending expanded rapidly, and the period in the early 1990s, when asset prices fell, resulting in the subsequent banking crisis and recession. The paper first briefly surveys the literature. Empirical research is then presented in three parts. Secondary sources are accessed to gain information on the mechanism of monetary policy conduct. New field work is then presented, which uses primary sources to probe the details of monetary policy implementation. Finally, econometric evidence is gathered to test various hypotheses concerning monetary policy procedures. The research successfully establishes the details and nature of the Bank of Japan's monetary policy implementation during the 1980s and early 1990s. The findings suggest the need for a modification of the generally prevailing view, as well as the need for further research on the actual implementation of monetary policy in other countries.     

数量型还是价格型货币政策比较——基于利率市场化角度的分析

利率市场化进程中,数量型还是价格型货币政策合适?文章考虑金融市场上的金融加速器特征,将其引入DSGE模型,通过校准、模拟,从宏观经济波动幅度、不同货币政策下冲击效应以及福利损失函数三方面综合分析了利率市场化过程中数量型和价格型货币政策有效性问题。研究结果显示,随着存款利率的上升,在熨平经济波动方面,价格型货币政策更有优势;在促进经济增长方面,数量型货币政策更有优势;对央行损失而言,价格型货币政策的损失更小。因此,中央银行应根据需要灵活的运用数量型和货币型搭配使用,做好数量型向价格型转变。     

金融二元结构与货币政策有效性

金融二元结构的存在是金融管制的必然结果,即正规金融与非正规金融并存。为了研究非正规金融对货币政策有效性的影响,首先利用改进的?值法估测出1994-2012年非正规金融的规模,结果显示,近几年,其已占正规金融规模的1/3左右。在此基础上,利用多种实证计量方法重点分析了非正规金融与货币政策有效性的关系,结果表明:非正规金融与作为货币政策中介目标的货币供给量M2存在长期稳定的协整关系,而且是促进M2扩张的Granger原因;同时,正规金融、货币当局债券发行与其国外资产均对货币供给量M2产生不同程度的影响。金融二元结构的存在造成中央银行无法精确观测和调控货币供给总量,削弱了央行货币政策制定和实施的效果。
