Money,Bonds, and the Liquidity Trap

This paper examines a search model of money and public bonds in which coordination frictions lead to multiple, Pareto ranked equilibria. Whether money and bonds are substitutes or complements, is not a primitive of the economy, but an equilibrium outcome. There exists an equilibrium resembling a liquidity trap, in which money and bonds are perfect substitutes, interest rates are zero, and monetary policy is ineffective; and a superior equilibrium in which money and bonds are complements, interest rates are positive and monetary policy has a liquidity effect. On this view, the liquidity trap is a belief-driven phenomenon.     

The role of liquidity constraints in the response of monetary policy to house prices

We analyse the optimal response of monetary policy to house prices in a New Keynesian framework. A positive wealth effect from housing is derived from liquidity constrained consumers. Housing equity withdrawal allows them to convert an increase in housing value into consumption and we show that monetary policy should react to house prices due to their effect on consumption by constrained agents. Moreover, we allow the share of liquidity constrained consumers to vary with house prices. Consequently, the optimal weights on expected inflation, the output gap and house prices in the optimal interest rate rule vary over time too.     

The Pigou effect: An elaboration

The ‘Pigou effect’ has drawn the attention of monetary theorists for three decades. We argue in this paper that the nature and significance of Pigou's (1943, 1947) comments on Keynes have been frequently misinterpreted. In particular, we suggest that Pigou's logic implies not only that monetary policy will be successful in escaping unemployment in the liquidity trap situation, but also that it is a Pareto optimal means of doing so.     

Bank liquidity creation,monetary policy,and financial crises

This paper examines the interplay among bank liquidity creation (which incorporates all bank on- and off-balance sheet activities), monetary policy, and financial crises. We find that: (1) high liquidity creation (relative to trend) – particularly off-balance sheet liquidity creation – helps predict crises, controlling for other factors; (2) monetary policy has statistically significant, but economically minor effects on liquidity creation by small banks during normal times, and these effects are even weaker during financial crises; (3) monetary policy has very little effects on medium and large bank liquidity creation during both normal times and crises. These findings suggest that authorities may wish to monitor bank liquidity creation closely in order to predict and perhaps lessen the likelihood of financial crises. They might also consider other tools to control bank liquidity creation, such as capital and liquidity requirements.     

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。     

美国货币政策对中国信贷市场的溢出效应研究

本文使用向量自回归误差修正模型(VECM)研究了美国货币政策对中国信贷市场的溢出性影响。研究发现,美国货币政策可以通过影响中国的信贷市场而作用于中国内生的广义货币供给。宽松的美国货币政策对中国信贷供给有正向影响。美元流动性通过该机制形成了对中国过剩流动性的溢出效应。在后危机时代,我们需要对美国货币政策可能的调整进行前瞻性的应对。     

特里芬两难的辨析

通过理论推导和实证分析,本文依次从可兑换性与流动性的关系、国际收支与流动性的关系,以及关键货币国家货币政策目标定位三个角度分析了特里芬两难,结论是特里芬两难并不成立。这意味着,现行国际货币体系并不存在根本性矛盾,经过较大改进后仍然可能在相当长的时期内存在;美国经常账户赤字的根本原因是其国内经济失衡,美国对由此导致的国际经济失衡应负主要责任。     

Scarcity of safe assets,inflation, and the policy trap

A goal of this paper is to make sense of the seemingly puzzling behavior of interest rates and inflation – and the role of central banks in that behavior – during and after the Great Recession, particularly in the United States. To this end, we construct a model in which government debt plays a key role in exchange, and can bear a liquidity premium. If asset market constraints bind, then there need not be deflation under an indefinite zero interest rate policy (ZIRP). Further, ZIRP may not be optimal under these circumstances. A Taylor-rule central banker could be subject to a ZIRP trap and persistently undershoot target inflation. As well, a liquidity premium on government debt creates additional Taylor rule perils, because of a persistently low real interest rate. We make a case that this is the key policy predicament currently faced by many central banks in the world.     

货币政策冲击对股票市场流动性的影响——基于Markov区制转换VAR模型的实证研究

本文首先对货币政策影响股市流动性的机理进行分析,在此基础上,尝试构建了一个新的股票市场流动性指标,通过引入MS-VAR模型,考察了货币政策在不同区制下对股市流动性的动态影响。基于MSIH(3)-VAR(4)模型和累积脉冲响应的结果表明,货币政策扩张有助于提高市场流动性,货币政策收紧,会导致市场流动性降低。但在不同区制下,影响程度存在显著差异,当股市处于膨胀期时,货币政策冲击对市场流动性的影响比股市处于低迷期时表现得更加明显。同时,股市收益率和股市波动率对股市流动性也存在显著影响。     

A Model of Monetary Policy Shocks for Financial Crises and Normal Conditions

Deteriorating economic conditions in late 2008 led the Federal Reserve to lower the target federal funds rate to near zero, inject liquidity through novel facilities, and engage in large‐scale asset purchases. The combination of conventional and unconventional policy measures prevents using the effective federal funds rate to assess the effects of monetary policy beyond 2008. We employ a broad monetary aggregate to elicit the effects of monetary policy shocks both before and after 2008. Our estimates align well with major changes in the Fed's asset purchase programs and yield responses that are free from price, output, and liquidity puzzles that plague other approaches.     

Excess liquidity,bank pricing rules,and monetary policy

This paper studies the implications of excess bank liquidity for the effectiveness of monetary policy in a simple model with credit market imperfections. The demand for excess reserves is determined by precautionary factors and the opportunity cost of holding cash. It is argued that excess liquidity may impart greater stickiness to the deposit rate in response to a monetary contraction and induce an easing of collateral requirements on borrowers – which in turn may translate into a lower risk premium and lower lending rates. As a result, asymmetric bank pricing behavior under excess liquidity may hamper the ability of a contractionary monetary policy to lower inflation.     

A Dilemma between Liquidity Regulation and Monetary Policy: Some History and Theory

History suggests a conflict between current Basel III liquidity ratios and monetary policy, which we call the liquidity regulation dilemma. Although forgotten, liquidity ratios, named “securities-reserve requirements,” were widely used historically, but for monetary policy (not regulatory) reasons, as central bankers recognized the contractionary effects of these ratios. We build a model rationalizing historical policies: a tighter ratio reduces the quantity of assets that banks can pledge as collateral, thus increasing interest rates. Tighter liquidity regulation paradoxically increases the need for central bank's interventions. Liquidity ratios were also used to keep yields on government bonds low when monetary policy tightened.     

Monetary Policy Transmission with Interbank Market Fragmentation

This paper shows how interbank market fragmentation disrupts the transmission of monetary policy. Fragmentation is the fact that banks, depending on their country of location, have different probabilities of default on their interbank borrowings. Once fragmentation is introduced into standard theoretical models of monetary policy implementation, excess liquidity arises endogenously. This leads short-term interest rates to depart from the central bank policy rates. Using data on monetary policy operations, I show that this mechanism has been at work in the euro area since 2008. The model is used to analyze conventional and unconventional monetary policy measures.     

Monetary policy and distribution

A segmented markets model of monetary policy is constructed, in which a novel feature is goods market segmentation, and its relationship to conventional asset market segmentation. The implications of the model for the response of prices, interest rates, consumption, labor supply, and output to monetary policy are determined. As well, optimal monetary policy is studied, as are the costs of inflation. The model features persistent nonneutralities of money, relative price effects of increases in the money supply, persistent liquidity effects, and a negative Fisher effect from a money supply increase. A Friedman rule is in general suboptimal.     

Does monetary policy determine stock market liquidity? New evidence from the euro zone

The recent financial crisis has been characterized by unprecedented monetary policy interventions of central banks with the intention to stabilize financial markets and the real economy. This paper sheds light on the actual impact of monetary policy on stock liquidity and thereby addresses its role as a determinant of commonality in liquidity. Our results suggest that an expansionary monetary policy of the European Central Bank leads to an increase of aggregate stock market liquidity in the German, French and Italian markets. Furthermore, the effect of monetary policy is significantly stronger for smaller stocks, suggesting a non-linear impact of monetary policy on stock liquidity.     

再析美国金融危机前的利率政策

全球金融危机与美国货币政策的变化密不可分,从低利率货币信贷扩张的流动性过剩到高利率的流动性紧缩,使宏观经济产生剧烈波动,前期低利率带来过剩的流动性,后期利率的提高造成巨量房地产泡沫的破灭。让美联储无视资产泡沫的原因是美联储货币政策一贯秉持的"泰勒规则"指导原则没有纳入资产价格因子,致使美联储货币政策调控失误。     

流动性覆盖率监管会影响货币政策传导效率吗？——来自中国银行业的证据

本文从流动性覆盖率监管要求出发,探讨了流动性监管与货币政策的协调机制问题。我们将流动性覆盖率监管要求纳入传统的Monti-Klein模型中,推导出流动性覆盖率监管对货币政策传导效率的影响及其作用机制。在此基础上,采用手工收集的我国65家商业银行2015—2019年半年度面板数据对理论假设进行实证检验。研究发现,流动性覆盖率监管要求会对货币政策传导效率产生影响,但这种影响取决于流动性监管约束下商业银行流动性管理行为的选择。商业银行主动调整融资结构、增强负债质量的行为在提高银行短期流动性水平的同时,也能显著提高货币政策传导效率,而流动性资产的囤积则可能降低货币政策传导效率。因此,应客观看待流动性覆盖率监管对货币政策传导效率的影响,引导商业银行的流动性管理行为,这将有助于实现流动性监管与货币政策有效传导的“双赢”目标。     

International monetary policy spillovers through the bank funding channel

In this paper, we examine the international transmission of monetary policies of major advanced economies (US, UK, euro area) through banks in Austria and Germany. In particular, we compare the role of banks’ funding structure, broken down by country of origin as well as by currency denomination, in the international transmission of monetary policy changes to bank lending. We find weak evidence for inward spillovers through a bank funding channel. The more a bank is funded in US dollars, the more its domestic real sector lending is affected by monetary policy changes in the US. This effect is more pronounced in Germany than in Austria. We do not find evidence for outward spillovers of euro area monetary policy.     

货币政策应对流动性过剩有效性研究:日本的经验

本文通过对日本流动性过剩与货币政策之间的关系进行实证研究,发现货币政策在应对流动性过剩的问题上缺乏足够的有效性,货币政策能够在一定程度上调节流动性,但宽松的货币政策容易制造过剩流动性而紧缩的货币政策却难以吸收过剩流动性,根除流动性过剩仅靠货币政策是不够的,需要进行产业和金融制度的升级和改革。     

日本超宽松货币政策的历程、效果及启示

日本央行提前启动了开放式资产购买措施,显示了尽快实现2％通胀目标的决心,但其会否重蹈历史的覆辙,还是会一举扭转日本经济长期的窘境,值得关注。文章在梳理日本央行长期实施超宽松政策历程的基础上,分析日本超宽松政策的效果,探究其陷入“流动性陷阱”的原因,并从中总结实施超宽松货币政策的经验和教训,以便能更好地理解货币宽松政策的传导机制、效果与局限性。
