中国货币政策利率传导机制有效性的实证研究

本文基于新颖的和交叉性统计数据,通过协整检验与Granger因果关系检验等方法,对中国货币政策的利率传导机制进行实证研究.实证分析结果表明:(1)我国货币政策的利率传导机制是低效的.(2)货币政策在整体上却有效.这从侧面可以证明:相比较于其他几个货币传导机制,我国的利率传导机制的阻塞效用更强,即其对货币政策总体绩效的贡献度相对最小.(3)利率传导机制还存在时滞效应.本文认为,解决目前我国利率传导机制低效性的主要方法还是要通过利率市场化的渐进推进.

Housing,consumption and monetary policy: how different are the first-, second- and third-tier cities in China?

This article presents an empirical analysis of the relationship between house prices and the real economy in China’s first-, second- and third-tier cities. A Structural Vector Autoregression model is applied to study the impacts of monetary policy shocks and housing demand shocks on various housing markets across China. We also investigate the role of house prices in the transmission mechanism of monetary policy. The results reveal that in first-tier cities, raising interest rates has a stronger negative effect on house prices. Also, as house prices decrease in first-tier cities, private consumption declines sharply. There is a stronger role of housing markets in the transmission of monetary policy shocks in these cities. Our findings indicate that interest rate adjustment could effectively curb spikes in housing prices in the first-tier cities, but the impact of such adjustments on household consumption must also be considered.     

货币政策对房地产价格调控的非对称效应——基于STR模型

从货币政策的非对称效应的角度,运用非线性模型——STR模型,探究了中国货币政策与房地产价格的关系。研究结果表明:货币政策对房地产价格的影响确实因所处经济周期阶段的不同而发生变化;货币政策与房地产价格之间存在非线性关系;不同经济增长水平下货币政策对房地产价格的调控效应是不对称的;在调控房地产价格方面,我国货币政策的信贷传导路径比利率传导路径更有效。     

货币政策对房地产市场冲击效力的动态测度

以货币政策传导渠道为理论依据,通过结构向量自回归(SVAR)模型构造货币政策对房地产市场的作用途径,可测度各种货币政策工具冲击对我国房地产市场供求的相对强度.实证分析结果表明,利率政策的冲击效力明显且持久,是调控房地产市场最有效的货币政策工具;紧缩的信贷政策仅能在短期内抑制房地产市场需求,长期效果欠佳;而货币供给量冲击对房地产市场的影响并不显著.相对于房地产需求,房地产市场供给对各种货币政策工具冲击的响应深度高,但响应速度较慢.     

利率市场化视角下的货币政策风险承担渠道问题研究*

利率市场化进程的深入可能会对我国货币政策传导、金融稳定等产生不可忽视的影响。基于此,本文研究了利率市场化对货币政策风险承担渠道的影响。结果表明：（1）我国存在货币政策风险承担渠道,且从利率市场化间接度量的维度来看,在考虑以直接效应来衡量的贷款利率市场化之后,银行的实际风险承担水平上升;但是在考虑以价格约束效应来衡量的存款利率市场化之后,其效果并不明显。（2）从利率市场化直接度量的方法来看,直接引入虚拟变量的研究发现贷款利率市场化会使得货币政策对银行风险承担水平的影响变得明显;进一步从利率市场化综合度量的维度,引入整体的利率市场化指数的方法则发现,随着利率市场化进程的深入,银行的实际风险承担水平会上升。（3）利率市场化对货币政策风险承担渠道的影响在不同类型银行间存在差异。     

Monetary policy channels in Brazil through the lens of a semi-structural model

We develop and estimate a medium-sized, semi-structural model for the Brazilian economy during the inflation targeting period. The model describes fairly well key features of the economy and allows us to decompose the transmission mechanism of monetary policy. In the baseline decomposition, the transmission mechanism is broken down into household interest rate, firm interest rate, and exchange rate channels. In addition, we carry out an alternative decomposition that allows us to evaluate the expectations channel as well. In both procedures, the household interest rate channel is the most important for explaining the response of output to a monetary policy shock. In the baseline decomposition of inflation, both the household interest rate and the exchange rate channels are the main transmission channels. However, in the alternative decomposition, the expectations channel accounts for the bulk of the inflation response.     

股票价格、实体经济与货币政策研究——基于我国1997-2011年的经验证据

本文运用格兰杰因果关系检验和向量自回归方法分析了1997年1月至2011年6月我国股票价格、GDP、通货膨胀率和货币政策的关系,实证结果表明,在中国,股票价格对通货膨胀的效应为正向,即股市上涨能带动通货膨胀水平的上涨。股票市场对GDP的影响短期内主要表现为替代效应,长期来看,则是财富效应和投资效应占主导;同时,货币供应量和利率对股票价格均有影响,但影响均不显著。通过格兰杰因果关系检验发现,利率变动导致货币供应量和股票价格发生变化。而货币供应量的变化影响着通货膨胀,也一定程度影响利率和股票价格。通过广义脉冲响应发现,中国人民银行紧缩性的利率政策并不能抑制股票价格上涨。增加货币供给短期内能够推动股市上涨,但长期对股市仍没有效果。     

The impact of Chinese monetary policy on co-movements between money and capital markets

From 2010 to 2017, with interest rate liberalization and capital market development in China, the impact of monetary policies on China’s financial markets underwent continuous evolution. Using the DCC-GARCH model, this study investigates the transmission process of monetary policies from the money market to capital markets (stock and bond markets). The results show that in the early stage the instability of the money and stock markets and the downturn in the bond market are primarily caused by the block of monetary policy transmission and the paucity of fund sources in the capital markets. Subsequently, the outbreak of the 2013 money shortage and the 2015 stock market crash are also closely related to monetary policies. In the later periods, the money and stock markets maintain a low degree of correlation for a long time, reducing the impact of destabilizing factors on the stock market. By contrast, with the advancement of interest rate reform and the optimization of bond market structure, the bond market is highly relevant to the money market. The central bank regulates the bond market more effectively using both traditional and innovative monetary policy tools.     

Bank behavior, incomplete interest rate pass-through, and the cost channel of monetary policy transmission

This paper employs a New Keynesian DSGE model to explore the role of banks within the cost channel of monetary policy transmission for shaping the interest rate pass-through from money market rates to loan rates. Banks extend loans to firms in an environment of monopolistic competition by setting their loan rates in a staggered way, which means that the adjustment of the aggregate loan rate to a monetary policy shock is sticky. We estimate the model for the euro area by adopting a minimum distance approach. Our findings exhibit that (i) financial costs are an important factor for price changes, (ii) frictions in the loan market have an effect on the propagation of monetary policy shocks as the pass-through from a change in money market rates to loan rates is incomplete, and (iii) the strength of the cost channel is mitigated as banks shelter firms from monetary policy shocks by smoothing loan rates.     

Transmission of monetary policy in times of high household debt

This paper explores whether the degree of household indebtedness can affect the effectiveness of monetary policy. We take an interacted panel VAR approach, using a panel of 23 countries, thereby obtaining several interesting findings, such as the responses of consumption and investment to monetary shocks are stronger in high levels of household debt. Furthermore, such responses become larger in a contractionary monetary policy stance rather than in an expansionary one, which suggests that monetary policy shocks have asymmetric effects. We have also found that monetary policy has a relatively larger impact in countries with higher share of adjustable-rate loans. Finally, we have found that when a country is in a high-debt state and in a contractionary policy stance, monetary policy is more powerful in countries with a higher share of adjustable-rate loans. We conjecture that these findings support the presence of a cash-flow channel with respect to the transmission of monetary policy in a high household debt state.     

股票市场的货币政策传导分析

货币政策的传导机制不是唯一的，金融市场的种种特征造成了货币政策传导的多样性，股票市场中的货币政策传导就具有独特的规律，在不与银行信贷的创造机制相连的前提下，信贷资金和股市资金的沟通是合理的，目前中国信贷市场和股票市场之间千丝万缕的关系，并没有为货币政策传导创造更加有效的机制基础，股票市场还不能成为货币政策的有效传导渠道。     

The effectiveness of monetary policy in steering money market rates during the financial crisis

The financial crisis has deeply affected money markets and thus, potentially, the proper functioning of the interest rate channel of monetary policy transmission. Therefore, we analyze the effectiveness of monetary policy in steering euro area money market rates by looking at (i) the predictability of money market rates on the basis of monetary policy expectations and (ii) the impact of extraordinary central bank measures on money market rates. We find that during the crisis money market rates up to 12 months still respond to revisions in the expected path of future rates, even though to a lesser extent than before August 2007. We attribute part of the loss in monetary policy effectiveness to money market rates being driven by higher liquidity premia and increased uncertainty about future interest rates. Our results also indicate that the ECB’s non-standard monetary policy measures as of October 2008 were effective in addressing the disruptions in the euro area money market. In fact, our estimates suggest that non-standard monetary policy measures helped to lower Euribor rates by more than 80 basis points. These findings show that central banks have effective tools at hand to conduct monetary policy in times of crises.     

Time-varying transmission efficiency of China’s monetary policy

This paper tries to investigate the time-varying characteristics of China’s monetary policy transmission from the impulse response evidence of both open-economy DSGE model and TVP-VAR model. We find that the transmission efficiency of price-based monetary policy has significantly improved over the sample period, while quantity-based monetary policy is weakening. The resume of exchange reform in 2010 also strengthens the exchange rate channel especially in terms of price-based monetary policy. Combining with the evidence from DSGE model underlines the importance of further interest rate liberalization and price-based monetary policy Taylor rule should also consider the exchange rate stability.     

中国货币政策的二元传导机制——"两中介目标、两调控对象"模式研究

The research, using VAR model and economic and financial data starting from January 1998 and expiring by June 2006, by econometric methods and theoretical analysis, examines the intermediate target and transmission channel of China’s monetary policy. The results are as followings: (1) Monetary supply M2 is a good indicator for China’s monetary policy, its prediction ability to economic variables is far above other monetary variables; (2) M2 is China’s monetary intermediate target because M2 reacts systematically to the industrial added value and CPI, and M2 innovation is made by the People’s Bank of China (PBC); (3) Monetary transmission channel does not exist in China basically, the main transmission channel is bank loans, credit quota is a de facto intermediate target, which regulates macroeconomy directly and induces the changes in M2, so there are two intermediate targets—credit quota and M2, which is fundamentally the same as the situation before 1998; (4) The two intermediate targets function in different fields—credit quota for real economy and M2 for the financial market, which is a realistic choice and PBC has successfully coordinated them. These conclusions are meaningful for the practices of China’s monetary policy, which indicates that we should pay more attention to the credit quota and take it as the core variable to regulate macroeconomy. Of course, this monetary transmission mode is only effective temporarily because there are many limitations in it. In the future, it is necessary to adopt the interest rate, which is more informative, as the intermediate target, which takes the marketization of the interest rate and exchange rate as the preconditions. __________ Translated from Jingji Yanjiu 经济研究 (Economic Research Journal), 2008, (10): 37–51     

The transmission of euro area monetary policy to financially euroized countries

This paper provides a comprehensive analysis of the interest rate pass-through of euro area monetary policy to retail rates outside the euro area, contributing to the literature on the consequences of unofficial financial euroization and on the transmission channels of monetary policy spillovers. The results suggest that in the long run, more than the one-third of all euro retail rates in euroized countries of central, eastern, and south-eastern Europe is linked to the euro area shadow rate. Compared with euro area monetary policy, the share of cointegration of the domestic monetary policy rate is on average lower, suggesting that domestic central banks in euroized countries with independent monetary policy can only partially control the “euro part” of the interest rate channel. Furthermore, euro area monetary policy shocks are fast and persistently transmitted into euro retail rates outside the euro area, which constitutes an additional channel of international shock transmission.     

The bank lending channel of monetary policy in EU countries during the global financial crisis

The study examines the existence of the bank lending channel of monetary policy in European Union (EU) countries. The paper advances current research on the monetary transmission mechanism in the following ways: Firstly, we analyze the differences between ‘old’ Economic Monetary Union (EMU) and ‘new’ EU countries. Secondly, we examine the key bank characteristics and monetary policy indicators that may have an impact on the bank lending channel. We assume that short-term market interest rates and monetary aggregate M2 affect banks' activities. We apply the generalized method of moments (GMM) with pooled data from 1999 to 2012. We show that in the pre-crisis period the effect of changing the short-term market interest rates on the bank lending channel of monetary policy is more pronounced among ‘old’ EMU countries, whereas the effect of M2 is significant during the period of the global financial crisis (GFC) among ‘old’ EMU countries. Last but not least the important finding is that banks in ‘new’ EU countries react differently to monetary shocks.     

REGIONAL EFFECTS OF MONETARY POLICY IN CHINA: EVIDENCE FROM CHINA'S PROVINCES

This study examines the provincial effects of monetary policy from 1978 to 2011 in China. We used the SVAR method to measure the magnitude and timing of each province's response to monetary policy shocks when considering the influences of spillover effects among provinces. Then we also explored the regional effects of monetary policy employing multiple linear regressions. The results confirm that provinces respond differently to monetary policy actions. It was found that in the short run, the influence of spillover effects on a province's response is very important, but in the long run, the negative influence of deposit transfers overtake the positive impact of the spillover effect. For the factors causing the regional effects on monetary policy, the results show that the interest rate channel is rather weak at the regional level in China. The bank lending channel can explain the regional effects of monetary policy to some extent. Thus in China, the bank lending channel is more effective than the interest rate channel at the regional level.     

基于标准泰勒规则的我国货币市场利率偏离估算

本文利用泰勒规则方法对我国货币市场利率偏离程度进行了估算。对我国货币政策反应函数的经验分析表明,我国货币政策并不符合稳定货币政策规则要求。标准泰勒规则具有良好的稳健性。根据泰勒规则原式及稳定货币政策规则最低条件计算结果表明,我国货币市场利率长期存在负的利率缺口,货币政策对通胀和产出缺口并不是稳定的,更不是最优的,货币政策存在着长期偏误。这对进一步理解我国的通货膨胀和宏观经济波动,合理评价货币政策,提供了新的视角。
