国际收支失衡下的中国货币政策——基于结构型VAR的经验研究

本文采用结构型VAR模型,旨在揭示中国国际收支失衡下货币政策的反应及其对于宏观经济波动的影响。我们发现:(1)针对经常项目和资本项目盈余,央行分别采取扩张性和紧缩性政策;(2)紧缩性货币政策会增加经常项目盈余,但对资本流动的影响很小;(3)净出口和净资本流入的正向冲击分别导致CPI的下降和上升。除净出口冲击降低CPI并伴随扩张性货币政策外,其他发现都符合理论判断,说明了央行针对国际收支失衡实施的货币政策的合理性。     

Financial Development,Financial Structure,and the Growth Effect of Monetary Policy: International Evidence

This paper investigates how financial development and financial structure affect the growth effect of monetary policy using panel data from 49 countries over the period 1980–2014. We find robust evidence that financial development has a significantly negative impact on the growth effect of monetary policy. We also find that the growth effect of monetary policy tends to be more pronounced as the financial structure of a country becomes more market-based. These results not only add interesting new evidence to the recent literature on the growth effects of monetary policy, but also provide some important insights into the financial determinants of monetary policy effects on economic growth, which have largely been ignored in the previous literature.     

货币供给、通货膨胀与产出波动的动态效应研究：1992—2013

本文基于包含随机波动率的时变参数向量自回归（SV—TVP—VAR）模型研究了货币供给冲击作用下我国货币政策传导的动态响应机制。实证结果表明：我国的货币传导机制具有明显的时变效应,SV—TVP—VAR模型能够很好的刻画货币传导机制中的时变特征。同时,货币政策传导机制中时变效应大于惯性效应。此外,我国的货币供给过程表现为逐渐增强的产出缺口驱动特征。进一步研究发现,增加货币供给量这种扩张性的货币政策在短期内具有真实效应,能够显著的影响实际利率和产出水平,然而从长期来看对实际利率和产出水平却缺乏永久性影响。     

Assessing the performance of inflation targeting in East Asian economies

This paper examines the implementation and performance of inflation targeting (IT) in four East Asian emerging market economies: Indonesia, Korea, the Philippines, and Thailand. It also examines monetary policy in Malaysia, a country that has not adopted IT. The study estimates policy reaction functions to test the links between the adoption of IT and use of a monetary policy rule. The impulse responses of prices to a monetary policy shock are also estimated to identify monetary policy impacts on prices. The findings on the monetary policies of the five economies can be summarised as follows. Korea has taken an inflation‐responsive and forward‐looking policy stance under inflation targeting, which has had an effect on the stability of prices. Indonesia and Thailand have conducted inflation‐responsive but backward‐looking policy stances, which have had no impact in terms of price stabilisation. The Philippines (which adopted IT but under a pegged exchange rate regime) and Malaysia have neither followed inflation‐responsive rules nor had policy impacts in terms of controlling inflation.     

融资成本能评价新型货币政策工具的有效性吗

提升货币政策效果是近年来我国宏观经济调控改革中的重要任务,而如何正确评价货币政策有效性则是这一任务的前提条件。基于此,结合我国经济新变化,文章在经典的CC-LM模型中纳入了新型货币政策工具,从理论上分析了新型货币政策工具对信贷利率与实际产出的传导机制,并应用具有时变参数的TVP-SV-VAR模型进一步检验了理论分析的结论。理论研究与实证检验一致得出：第一,从对实际产出的影响来看,中期借贷便利为代表的新型货币投放方式是有效的;第二,中期借贷便利仅能降低短期信贷利率,而长期将提升信贷利率;第三,中期借贷便利与LPR报价市场的市场化程度提升可强化货币政策有效性。此外,实证研究还表明,依靠中期借贷便利方式投放基础货币会造成吉布逊谜团的现象,因此能否降低融资成本并不能作为评价货币政策有效性的指标。籍此,文章对如何优化新型货币政策有效性提出了富有建设性的政策建议。     

论中美货币政策差异及其分配效应

本文通过对货币政策的分析,认为货币政策的增长效应是有限的,分配效应是具有破坏性的,其造成的社会财富的剥夺和转移恶化了收入分配。因此,货币主义的单一规则对总量管理仍然具有很强的指导意义。本文认为,货币供给的总量管理应该永远是稳健的,结构调整应更多地依靠利率和财政政策。美元的弱势和中国的强劲增长为人民币国际化打开了空间。中国应该抓住历史机遇,积极推进人民币自由化、国际化进程。     

经济政策不确定性视角下宏观杠杆的调控效应及其策略选择

新常态下保证宏观杠杆稳步下降是供给侧结构性改革的重要任务之一。以中国经济政策不确定性为门限变量,构建了包括经济政策不确定性、宏观经济政策以及宏观杠杆在内的门限结构向量自回归(T-SVAR)模型,研究高低两种政策不确定性区制下我国需求端货币政策与财政政策以及供给端金融改革政策对宏观杠杆的调控效应。结果显示,三种政策均存在明显的门限效应且在中长期内均出现逆转,区别在于,虽然货币政策对宏观杠杆的短期作用效果最为显著,但当政策不确定性水平快速攀升时,其调控效果会略微降低,而此时财政政策和金融供给侧结构性改革能有效平抑过高的杠杆率增速,且在长期依旧保持一定的调控效果。因此,央行在对宏观杠杆进行调控时应依据各政策调控效应的阶段性特征进行搭配使用,同时通过推进资本市场基础性制度改革,优化融资结构,为实现宏观政策调控效果的最大化奠定基础。     

金融排斥:货币政策失效的另一种解释

至今为止,关于货币政策有效性的研究一直存在争议并受到学者和政策调控部门的持续关注。各种学派在理论上对货币政策有效与否的争论并没有阻碍学者们对现实货币政策有效性的探讨,大量研究都集中在货币传导机制本身及其影响因素上。本文从金融排斥角度解读货币政策可能失效的原因,并指出忽视金融排斥存在的货币政策可能导致的问题,从而赋予金融包容政策新的职能。     

Sectoral Effects of Monetary Policy: Evidence from Malaysia

The present paper analyzes the effects of monetary policy shocks on aggregate and eight sectoral outputs for Malaysia using vector autoregressive models. In line with many existing studies on Malaysia, the results are supportive of the real effects of monetary policy shocks. More importantly, we find evidence suggesting sector-specific responses to innovations in monetary policy. In response to positive interest rate shocks, we note that the manufacturing, construction, finance, insurance, real estate and business services sectors seem to decline more than aggregate production. By contrast, we observe the relative insensitivities of agriculture, forestry and fishing, mining and quarrying, electricity, gas and water to interest rate changes. The results, therefore, seem to confirm potential disparities in the effect of monetary policy on real sectoral activities.     

Measuring Monetary Policy in a Small Open Economy with Managed Exchange Rates: The Case of Taiwan

We use sign restrictions to identify monetary policy for a small open economy with heavily managed exchange rates. We apply the proposed sign restrictions to the Taiwanese case, where existing studies tend to find no clear effect of monetary policy shocks on the output and price level. Our principal findings are that a contractionary monetary policy shock causes a permanent and significant decline in real gross domestic product, broad money, and price level. Our identification scheme is able to avoid the puzzling impulse responses from which other identification schemes more or less suffer. The fact that monetary policy has not been correctly identified may have led existing studies to conclude that monetary policy is ineffective.     

Monetary Policy and Borrowers’ Loan Defaults: Research Based on Data from Renrendai

This paper uses Renrendai data to study the relationship between monetary policy and the default behavior of borrowers, and analyzes the transmission channels. The research shows that tight monetary policy will lead to a significant increase in a borrower's probability to default, and this effect will continue for several months. There may be two transmission channels: (i) monetary policy changes a debtor's liquidity through credit and balance sheet channels, which directly affects their current repayment behavior; and (ii) monetary policy may affect a borrower's investment, production and profitability, thus changing their long‐term solvency. The paper also finds that the repayment behavior of productive borrowers is more susceptible to monetary policy than consumptive borrowers, and that the default behavior of borrowers in coastal provinces is more susceptible to monetary policy than of borrowers in inland provinces. These findings provide new evidence for understanding how monetary policy affects individual behavior and its transmission mechanisms.     

DSGE模型框架下我国货币政策规则的比较分析

货币政策规则是中央银行为了保持通货膨胀和产出稳定并使经济更快发展所使用的货币政策的指导原则。目前,通行于各个国家的货币政策规则主要有利率规则和货币供应量规则。过去一段时间以来,西方发达国家都已逐渐从货币供应量规则过渡到利率规则,而在我国不管是应用方面还是理论研究方面,对于哪一个货币政策规则更适合我国始终都还没有定论。因此,本文试图在DSGE模型的框架下,对我国的货币政策规则进行比较分析。结果得出,相比于货币供应量规则,利率规则下:(1)货币政策更有效;(2)技术冲击所引起的通货膨胀和产出波动更小;(3)技术冲击对通货膨胀和产出的影响更短暂。因此,研究得出,我国更适合使用利率的货币政策规则。     

The interest rate–inflation relationship under an inflation targeting regime: The case of Turkey

This paper examines the relationship between nominal interest rates and the expected inflation rate for the Turkish economy between 2002 and 2009, a period when the inflation-targeting regime was implemented as monetary policy. We use the test of cointegrating rank with a trend-break (a method introduced by Inoue, 1999) and we also apply exogeneity tests. Empirical findings indicate that monetary policy rates depend on inflationary expectations; long-term interest rates are affected by monetary policy; and the weak form of the Fisher effect is valid. This evidence implies that monetary policy has actually influenced the real long-term interest rates; the inflation targeting regime pursued by the Central Bank of Turkey is reliable; and hence realized inflation has remained close to its targeted level.     

中国货币政策数量效果的实证研究

文章主要运用了单位根检验、协整检验、格兰杰因果关系检验、脉冲响应函数和方差分解等计量经济学方法,利用1994年到2004年的季度数据,对货币供应量、利率这两个重要货币政策变量与GDP之间的关系进行了计量分析,利率对实体经济的影响不显著;不同层次的货币供应量都能对经济产生影响,但它们对GDP的作用效果是有差异的.为提高我国货币政策的效果,实现我国货币政策的目标提出了相关的政策建议.     

中国货币政策非对称效应形成机理研究——基于价格传导机制的视角

中国货币政策具有显著的非对称效应,紧缩性货币政策对产出的影响力度强于扩张性货币政策。本文以价格粘性为核心构建菜单成本模型,从货币政策价格传导渠道分析货币政策非对称效应的形成机理。研究表明,货币政策非对称效应的主要成因是非对称的价格传导渠道。企业面临货币政策冲击时,遵循菜单成本和扭曲成本孰低原则决定调整价格还是产量。降价的菜单成本低于涨价成本以及扭曲成本随通货膨胀趋势呈非线性变化共同导致了非对称的价格粘性,由此产生的非对称货币政策传导机制是货币政策非对称效应的形成机理。因此,货币政策效果随通货膨胀率而变,货币政策效应非对称程度在不同的通货膨胀率区间存在差异,随通货膨胀率的上升呈现出先减后增再减的驼峰形趋势。本文进一步通过构造状态空间模型实证检验了理论模型在中国的适用性。为了实现经济稳定增长,中央银行制定货币政策时不仅要决定政策实施方向和力度,还应考虑经济所处的通货膨胀率区间。     

人民币国际化对货币政策有效性的影响

人民币国际化是否影响货币政策有效性?是人民币国际化程度提高之后货币大规模跨境流动而引起的担忧。文章研究发现,在给定其他因素不变的情况下,人民币国际化程度的提高放大了境外汇率变动对国内经济产出和价格的影响。因此,人民币国际化背景下,中央银行应将境外汇率失衡纳入货币政策的反应函数,反应系数取决于境外利率、产出和价格对境外货币需求的决定系数。理论分析还表明,人民币国际化程度不影响货币政策对国内价格的有效性,而是否影响货币政策对国内经济产出的有效性,则取决于经济结构特征。实证结果表明,目前人民币国际化未对国内利率、产出和价格带来明显冲击,且无论是在M0层次,还是在M2层次,人民币国际化均未明显影响国内货币政策有效性。     

Monetary Policy and Sectoral Bank Lending in Malaysia

Abstract

Unlike most studies on the effect of monetary policy on bank lending, this article intends to answer the question whether the tightening of monetary policy in Malaysia before and after the financial crisis in 1997 affected differently the commercial bank lending to various sectors of the economy. To achieve the objective, Vector Autoregressive Regression (VAR) method was used to generate impulse response function and variance decomposition to trace the impact of a shock in monetary policy on bank lending in Malaysia. The results show that a monetary policy tightening in Malaysia gives a negative impact on all the sectors. Analyzing sectoral responses to monetary shocks, evidence is found that some sectors are more affected than the others. The manufacturing, agricultural, and mining sector seems to decline more than the aggregate bank lending in response to interest rate shock.     

Monetary Policy in the Industrial World: Reflections on some Basic Issues

Abstract

This paper is a general assessment of monetary policy in major OECD countries during the 1990s. Within a simple policy framework that combines money growth, nominal income, and an open economy IS-LM type Mundell-Fleming model, the paper discusses the major strands in the conduct of monetary policy in developed industrial economies. It throws light on such problems as “rules versus discretion”, management of exchange rates, the effect of monetary changes on income and prices, and the rupture of monetary policy with other instruments of economic policy that also affect the economy.     

A role model for China? Exchange rate flexibility and monetary policy in Japan

A substantial number of papers have proposed to allow for more exchange rate flexibility of the Chinese yuan. But few papers have tried to project how Chinese monetary policy will behave under flexible exchange rates. As Japan provides an important role model for China, this paper studies the role of the yen/dollar exchange rate for Japanese monetary policy after the shift of Japan from a fixed to a floating exchange rate regime. In contrast to prior studies, we allow for regime shifts in the impact of the exchange rate on monetary policy. The results show that the exchange rate had a substantial impact on Japanese monetary policy in periods of appreciation. This implies that repeated attempts to soften the appreciation pressure by interest rate cuts have led Japan into the liquidity trap. The economic policy conclusion for China is to keep the exchange rate pegged (to the dollar).     

The transmission mechanism of monetary policy in Japan: Evidence from banks' balance sheets

We examine how banks' responses to monetary policy vary according to their balance sheet using Japanese bank data from 1975 to 1999. We find that the effect of monetary policy on lending is stronger for banks that are smaller, less liquid, and more abundant with capital. The effects of bank balance sheet on monetary transmission are different by bank types, policy stances and borrowers' industries. Our results imply that a lending channel of monetary transmission exists, that the effect of expansionary monetary policy is attenuated if banks' capital is scarce, and that the effect of monetary policy on the allocation of funds depends on banks' balance sheets.
