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。     

货币供应量、利率与银行系统性金融风险——基于CoVaR方法的实证研究

在常态化疫情防控的背景下,商业银行系统性金融风险有上升迹象,这对央行实施货币政策工具和力度的把握提出了更高要求。本文利用条件在险值模型检验了我国货币供应量、利率与银行系统性金融风险的关系。研究结果表明,货币供应量和利率与银行系统性风险之间的关系不是线性的,而是U型的,即存在最优的货币供应量和利率能够使商业银行的系统性金融风险最低。当货币供应量和利率小于这个最优组合时,增加货币供应量和提高利率能够有效降低商业银行的系统性金融风险;而当货币供应量和利率大于这个最优组合时,增加货币供应量和提高利率反而会增加银行系统性金融风险,进而降低商业银行的金融稳定性。     

The International Bank Lending Channel of Monetary Policy Rates and QE: Credit Supply,Reach‐for‐Yield,and Real Effects

We identify the international credit channel by exploiting Mexican supervisory data sets and foreign monetary policy shocks in a country with a large presence of European and U.S. banks. A softening of foreign monetary policy expands credit supply of foreign banks (e.g., U.K. policy affects credit supply in Mexico via U.K. banks), inducing strong firm‐level real effects. Results support an international risk‐taking channel and spillovers of core countries’ monetary policies to emerging markets, both in the foreign monetary softening part (with higher credit and liquidity risk‐taking by foreign banks) and in the tightening part (with negative local firm‐level real effects).

基于“六月货币荒”现象的反思与启示

自2008年爆发国际金融危机以来,对于金融市场的货币供给而言,中央银行先后实施适度宽松和稳健的货币政策,保证了银行体系流动性的充分供给;商业银行保持着低不良贷款率和正常杠杆率,也不会明显削弱其贷款创造能力以及货币供给水平;个人偏好和支付便利导致公众在特定时段更多地持有通货的行为,即使有削弱货币乘数的作用,其影响也是极其轻微和短暂的.因此可以断定,“六月货币荒”并非真实的货币荒,而是某些货币表象的欺骗性所致.“六月货币荒”现象的重要启示是,中央银行的货币政策意向要更加透明,商业银行要加强流动性风险管理和资产负债管理,公众要权衡个人偏好和支付便利与持有通货的货币性成本等诸多因素.这是消除货币表象的欺骗性,避免类似“六月货币荒”现象的出现,以及防止道德风险和逆向选择的基本要求.     

Sovereign risk and the bank lending channel in Europe

The main purpose of this article is to analyze how sovereign risk influences the loan supply reaction of banks to monetary policy through the bank lending channel. Additionally, we aim to test whether this reaction differs in easy and tight monetary regimes. Using a sample of 3125 banks from the euro zone between 1999 and 2012, we find that sovereign risk plays an important role in determining loan supply from banks during tight monetary regimes. Banks in higher sovereign risk countries reduce lending more during tight regimes. However, we find little evidence to support any relationship between sovereign risk and loan supply reaction to monetary policy expansions. These results are very interesting for the way monetary policy is conducted in Europe. Banking union, banking system strength, and the budget control of governments would be necessary measures to reduce the heterogeneous transmission of the monetary policy in the euro zone.     

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。     

A Model of QE,Reserve Demand,and the Money Multiplier

Quantitative easing (QE) programs have driven unprecedented expansions in the supply of central bank reserves around the world over the past two decades, fundamentally changing the implementation of monetary policy. The collapse in money multipliers following QE episodes has often been interpreted as implying banks are happy to passively hold most of the reserves created by QE. This paper develops a simple microsimulation model of the banking sector that adapts the traditional money multiplier model and allows for bank reserve demand to be inferred from monetary aggregates. The model allows the use of unwanted reserves by banks to play out over time alongside QE purchases and incorporates both significantly higher reserve demand after 2008 and capital constraints. With these additions, the model explains the persistently lower money multipliers seen in the United States following QE, as well as the growth in commercial bank deposits. The model suggests the demand from banks for reserves has increased substantially since the introduction of QE but not to the point where banks are passively absorbing all newly created reserves.     

Interest rate derivatives at commercial banks: An empirical investigation

I analyze the effects of bank characteristics and macroeconomic shocks on interest rate risk-management behavior of commercial banks. My findings are consistent with hedging theories based on cost of financial distress and costly external financing. Banks with higher probability of financial distress manage their interest rate risk more aggressively, both by means of on-balance sheet and off-balance sheet instruments. As compared to the derivative users, the derivative non-user banks adopt conservative asset-liability management policies in tighter monetary policy regimes. Finally, I show that the derivative non-user bank's lending volume declines significantly with the contraction in the money supply. Derivative users, on the other hand, remain immune to the monetary policy shocks. My findings suggest that a potential benefit of derivatives usage is to minimize the effect of external shocks on a firm's operating policies.     

货币政策对银行间市场流动性影响效应的实证研究及启示

银行间货币市场是央行实施货币政策的重要平台，研究货币政策对银行间市场流动性的影响对于完善商业银行日常流动性管理具有重要意义。文章在设定银行间市场流动性测度指标与梳理货币政策工具对市场流动性的影响机制的基础上，分别使用事件分析法和时间序列模型对不同政策工具的影响效应进行实证分析，得出相关分析结论，并总结其对于完善商业银行日常流动性管理的启示。     

支付系统发展对货币政策操作效果的影响

在以货币供给量为中介目标的情况下,支付系统发展提高了公开市场操作投放或回笼基础货币的效率,增加了货币乘数及货币流通速度。为达到相同的货币供给量目标,支付系统运行效率越高,公开市场操作投放(或回笼)的基础货币可越少。此外,支付系统的发展提高了资金周转效率,增加了银行体系的流动性,支付系统发展将弱化法定存款准备金率提高的效果。本文还探讨了支付系统发展对以利率为中介目标的货币政策操作效果的影响。     

On the role of Islamic and conventional banks in the monetary policy transmission in Malaysia: Do size and liquidity matter?

This paper empirically investigates the impact of monetary policy on the credit supply of Islamic versus conventional banks of Malaysia using an unbalanced panel dataset over the period 2005-2016. While estimating the effects of three alternative measures of monetary policy on banks' credit supply, we include several bank-specific and macroeconomic variables in the specification as control variables. We provide strong evidence on the existence of the credit channel of monetary policy transmission mechanism in Malaysia. Yet, we show that Islamic banks respond considerably less to changes in monetary policy instruments as compared to their conventional counterparts. We also find that the monetary policy measures affect small-sized banks and less-liquid banks more as compared to large-sized and more-liquid banks. Our findings suggest that for an effective monetary policy, there is a vital need to consider the nature of Islamic banking while devising any monetary policy instruments to manage credit supply in the economy.     

货币政策对流动性风险的影响——基于银行信贷行为视角

本文基于我国现实背景和《巴塞尔协议Ⅲ》,利用2008年至2017年间194家商业银行的相关数据,对我国银行净稳定资金率进行了度量,并在此基础上,检验了货币政策对我国商业银行流动性风险的影响,探究了其影响机理和传导渠道。研究表明:扩张型货币政策会提高商业银行的流动性风险;不同经济环境下,货币政策对流动性风险的影响存在差异但不具备异质性;不同类型的商业银行中,货币政策对流动性风险的影响不具有异质性;在货币政策对流动性风险的影响中,银行信贷行为是重要的传导渠道。因此,央行可基于货币政策对流动性风险的影响差异进行相机抉择;商业银行则要加强信贷规模和质量的管理,优化资产结构,通过弱化信贷渠道作用来降低货币政策对银行流动性风险的不良影响。     

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。     

Aggregate uncertainty and the supply of credit

This paper presents a model in which a bank can exhibit self-insurance with loan supply contracting when uncertainty increases. This prediction is tested with U.S. commercial banks, where identification is achieved by looking at differential effects according to banks’ capital-to-assets ratio (CAR). Increases in uncertainty reduce the supply of credit, more so for banks with lower levels of CAR. These results are weaker for large banks, and are robust to controlling for monetary policy, to different measures of uncertainty, and to breaking the dataset in subsamples. Quantitatively, the effect of uncertainty shocks on credit supply is about as important as that of monetary policy shocks.     

Financial Dampening

We propose a novel mechanism, “financial dampening,” whereby loan retrenchment by banks attenuates the effectiveness of monetary policy. The theory unifies an endogenous supply of illiquid local loans and risk sharing among subsidiaries of bank holding companies (BHCs). We derive an instrumental variable (IV) strategy that separates supply-driven loan retrenchment from local loan demand by exploiting linkages through BHC internal capital markets across spatially separate BHC member banks. We estimate that retrenching banks increase loan supply substantially less in response to exogenous monetary policy rate reductions. This relative decline has persistent effects on local employment and thus provides a rationale for slow recoveries from financial distress.     

The Effects of the Sharing Economy: How Does Internet Finance Influence Commercial Bank Risk Preferences?

In this article, we provide an evidence on the effects of the sharing economy by studying internet finance. It aims to explore how internet finance affects the relationship between commercial bank risk preferences and monetary policy, and discusses whether this impact varies across heterogeneous banks. The results suggest that having a loose monetary policy encourages a preference for risk. In addition, internet finance alters the sensitivity of bank risk behavior to monetary policy. Internet finance has a heterogeneous influence, depending on a bank’s ownership (i.e., state or private) and size. At privately owned banks, internet finance has only a moderate impact on the bank risk-taking transmission channel of monetary policy, unlike the subsample of large banks.     

国库库存纳入货币统计口径的可行性分析

货币供应量是我国货币政策的中介目标,目前我国货币供应量调控成本巨大,调控目标越来越难以实现,一些经济学家提出扩大货币统计口径的范围,给出了M3、M4等货币供应量指标,以引起货币当局对全社会资金的重视。与此同时,我国国库库存余额逐年加大,季节性波动明显,国库库存变动对与货币供应量和宏观经济的影响越来越大,在货币政策操作中需要密切关注国库库存的运行变化。本文首先描述了我国国库库存与货币供应量的特征,并分析了两者关系;接着探讨了将国库库存纳入货币统计口径的理论依据;然后利用近十年的数据检验将国库库存纳入货币统计口径后的实际效应;最后得出:货币当局将国库库存变量纳入中介目标监控体系,将有助于提高货币政策的有效性,并在结论的基础上给出相应的政策建议。     

外资银行信贷行为对我国货币供应量影响的实证分析

目前,同业往来是外资银行人民币资金的重要来源,短期贷款是外资银行资金运用的主要渠道。外资银行信贷行为不受信贷调控指导,增加了货币供给的不确定性,对货币供应量的可控性产生了影响。外资银行对我国各个区域货币供给影响程度差异也很大。实证分析发现,外资银行贷款已经开始对我国M1产生了一定的影响,需要引起宏观金融调控部门的关注。     

The competition for deposits and the impact of monetary policy

Financial intermediation in Britain can be said to have reached maturity before the war, since when the growth of banks has been critically a question of market share. Until the shift in monetary policy away from direct restriction of bank lending that began about nine years ago, credit restriction added to other factors, like taxation and the bank cartel, limiting the ability of the banks to compete. The author argues that an open-market policy directed toward money supply control need not discriminate against banks. However, the re-introduction of bank lending restrictions through the use of Special Deposits and, even more so, through the use of Supplementary Special Deposits has worked to favour non-bank deposit intermediaries. The distortions caused by the Supplementary Special Deposits not only discriminate against the banks; they are also likely to undermine the use of monetary policy itself. What are required are government policies, especially with regard to the size of the public sector borrowing requi rement, that make possible the goal of a non-discriminatory open-market policy, without the need for direct controls on lending by financial institutions.
