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。     

Which Vested Interests Do Central Banks Really Serve? Understanding Central Bank Policy Since the Global Financial Crisis

Inspired by Thorstein Veblen’s ideas, I analyze the behavior of central banks from the perspective of how institutions are captured by vested interests. Since the global financial crisis in 2008, there has been a shift in the conduct of monetary policy. Much like the behavior of asset holders themselves, who, in times of crisis, sought to trade off lower returns with more stable asset values, monetary policy changed from a de facto policy of stabilizing rentier income to one of preserving asset prices or rentier wealth. I analyze this particularly through the lenses of what happened with quantitative easing (QE) in the US, which coincided with a collapse of real interest rates, while asset prices were stabilized. This can also be seen in the way the banking sector was supported by QE where the market for mortgage-backed securities was sustained even as it actually meant a lower profitability for the overall U.S. banking sector during the QE interventions.     

The eurozone financial crisis: debt,credit ratings and monetary and fiscal policy

This paper discusses the eurozone financial crisis. It argues that it was largely the result of a common monetary policy not being suitable for individual countries which led to excessive private and public borrowing and a debt crisis. Neither borrowing rates nor credit ratings anticipated the crisis. Fundamental changes to eurozone governance are being proposed. The paper examines whether instead there might be a market solution if financial markets priced risk better. Accordingly, a more timely way of obtaining credit ratings is shown.     

The 2014–15 Financial Crisis in Russia and the Foundations of Weak Monetary Power Autonomy in the International Political Economy

ABSTRACT

This article contributes to international political economy debates about the monetary power autonomy (MPA) of emerging market and developing countries (EMDs). The 2014–15 Russian financial crisis is used as a case study to explore why an accumulation of large international reserves does not provide protection against currency crises and macroeconomic adjustments in EMDs. The analysis centres on the interplay between two dimensions of MPA: the Power to Delay and the Power to Deflect adjustment costs. Two structural factors condition Russia’s low MPA. First, the country’s subordinated integration in global financial markets increases its financial vulnerability. The composition of external assets and liabilities, combined with cross-border capital flows, restrict the use of international reserves to delay currency crises. Second, the choice of a particular macroeconomic policy regime embraced the financialisation of the – mainly state-owned – Russian banking sector, thus making it difficult to transform liquidity inflows into credits for enterprises. Russia’s main comparative advantage, hydrocarbon export revenues, is not exploited. The type of economy created due to the post-Communist transition means that provided ‘excessive’ liquidity remains in the financial system and is channelled into currency arbitrage. This factor increases exchange rate vulnerability and undermines Russia’s MPA.     

A Macro-Level Account of Money and Credit to Explain Gendered Financialization

ABSTRACT

The paper intervenes in the debate on macroeconomics, money, gender, and financialization. Generally, there is an omission in gender studies on gender-specific effects of monetary policy. Not only is there a blind-spot about the role of monetary policy in feminist political economy, there is equally a blind-spot in meso-level analysis which focus on the social construction of institutional mechanisms and the predatory market power of oligopolistic banks. Yet, monetary policy is neither neutral in the short-term nor long-term. Such policies have gender-differentiated effects on employment, income, consumption, savings which in turn have feed-back effects on economic growth. My intent is to focus on the changing role of monetary policy and highlight the omission in gender studies on financialization, as well as argue that the shift of the credit cycle to fictitious capital (future revenue) is one of the central explanatory variables in the predatory banking model of subprime lending. Yet, the financial crisis of 2007 did not usher in a normalisation of the credit and finance system. Exactly the opposite happened. Unconventional monetary policy continues to facilitate a credit system based on future claims which has gendered distributional effects, in the process increasing the wealth inequality on a global scale.     

Liquidity risk and financial competition: Implications for asset prices and monetary policy

This paper studies the implications of banking competition for capital markets and monetary policy. In particular, I develop a two-sector monetary growth model in which a group of agents is exposed to liquidity shocks and money is essential. Banks insure depositors against such risk and invest in the economy's assets. In this setting, I compare an economy with a perfectly competitive banking sector to an economy with a fully concentrated financial sector. Unlike previous work, banks can have market power in both deposits and capital markets. Compared to a perfectly competitive financial sector, I demonstrate that a monopolistic banking system can have substantial adverse consequences on capital formation, assets prices, and the degree of risk sharing. Furthermore, multiple steady-states can emerge and the economy becomes subject to poverty traps. More importantly, market power in financial markets may overturn the Tobin effect present under a perfectly competitive financial sector. This necessarily happens in economies with high degrees of liquidity risk and low levels of capital formation.     

Public good,collective action and financial regulation

The economy‐wide liberalization reforms implemented from the 1980s onwards in major capitalist economies had deep impact on financial markets. Public financial regulation has been replaced by self‐regulation, financial innovations proliferated and gave rise to many diversified and complex speculative operations that financialized most economic decisions and actions. Recurrent instabilities and crises became common ground in advanced as well as in emerging market economies and converged on the global systemic crisis in 2007–08, notwithstanding the efficient market doctrine that kept supporting financial liberalization. This crisis raised concerns about the relevance of market‐based financial regulation with regard to the systemic viability of capitalist economies and brought forward the central role of financial regulatory framework in the sustainable working of open societies. This article considers financial stability as a collective action problem through the lens of the literature on the commons and public goods. It seeks to contribute to the development of a relevant paradigm of collective action in the provision of a particular public good, financial stability, through a particular public action, financial regulation. After recalling the broad outlines of the evolution of financial markets and the institutional environment in the last decades, the monetary and financial characteristics of a capitalist economy are presented. The monetary and financial structure turns out to be a public infrastructure. The criticalness of financial transactions for the whole economic society together with the non‐rivalrousness and non‐excludability of financial stability determine the very publicness of the latter. The continuity of financial relations fundamentally needs a viable financial system. However, this is a complex issue as it falls into the classical opposition “private vs public” and calls for a collective action framework consistent with the characteristics of a financialized economy. This article argues that financial stability cannot be ensured through individual‐decision‐based market relations because of the endogenous limits of individual actions and the systemic nature of instabilities they can provoke. A specific treatment of finance as a public utility and of financial stability as a public good is then required. The study on the organization and management of financial markets, namely financial governance issue, ultimately leads to consider financial regulation as a collective action problem that calls for a public supervision framework through an extra‐market macroregulation, apt to allow economy to work in a viable way.     

Alternative Monetary Targets,Instruments and Future Monetary Policy Frameworks

ABSTRACT

This article expands on the debate of whether merely controlling inflation can be considered a good outcome in terms of monetary policy, discussing proposals for adopting alternative monetary targets (e.g., price level, nominal GDP), alternative instruments (e.g., monetary finance, central bank digital currencies), for enlarging central banks' mandates (e.g., incorporating employment, wages, inequality, environmental objectives) and for the design of future monetary policy frameworks.

We argue that in the coming years, central banks should not simply maintain their pre-2008 standards by de-implementing unconventional monetary policies. Instead, they must take advantage of their past and recent experiences in order to improve, under an evolutionary perspective, future monetary policy and financial stability frameworks. Based on this, measures implemented since the 2008 crisis would have three possible treatments in new frameworks: i) be discarded, due to their predominantly adverse effects; ii) not be regularly implemented, but be used as backstop mechanisms if needed; iii) be incorporated as regular measures of monetary policy/financial stability frameworks. Accordingly, monetary and financial stability authorities will increasingly need to evolve and engage in a continuously adaptive and innovative process in order to face challenges posed by financial markets that are becoming more dynamic, innovative, complex, interconnected and globalised.     

Financial market segmentation,stock market volatility and the role of monetary policy

We study a segmented financial markets model where only the agents who trade stocks encounter financial income risk. In such an economy, the welfare-maximizing monetary policy attains the novel role of redistributing the traders' financial market risk among all agents in the economy. In order to do that, optimal monetary policy reacts to financial market movements; it is expansionary in bad times for the financial markets and contractionary in good ones. In our quantitative exercise, a dividend shock generates different policy responses and consumption paths among the optimal and the 2% inflation targeting policy. The latter implies large distributional welfare losses and risk sharing losses of similar magnitude with those generated by business cycle fluctuations. In addition, the optimal monetary policy does not minimize stock price volatility and implies lower inflation volatility than other commonly used policies.

Measuring the effectiveness of US monetary policy during the COVID-19 recession

The COVID-19 recession that started in March 2020 led to an unprecedented decline in economic activity across the globe. To fight this recession, policy makers in central banks engaged in expansionary monetary policy. This paper asks whether the measures adopted by the US Federal Reserve (Fed) have been effective in boosting real activity and calming financial markets. To measure these effects at high frequencies, we propose a novel mixed frequency vector autoregressive (MF-VAR) model. This model allows us to combine weekly and monthly information within a unified framework. Our model combines a set of macroeconomic aggregates such as industrial production, unemployment rates, and inflation with high-frequency information from financial markets such as stock prices, interest rate spreads, and weekly information on the Fed's balance sheet size. The latter set of high-frequency time series is used to dynamically interpolate the monthly time series to obtain weekly macroeconomic measures. We use this setup to simulate counterfactuals in absence of monetary stimulus. The results show that the monetary expansion caused higher output growth and stock market returns, more favorable long-term financing conditions and a depreciation of the US dollar compared with a no-policy benchmark scenario.     

The role of exchange rate in inflation targeting: the case of Turkey

ABSTRACT

The role of the exchange rates in emerging market economies that have adopted inflation targeting (IT) is a critical and contentious issue in the relevant literature. This article investigates whether an exchange rate-augmented Taylor rule describes the Central Bank of Republic of Turkey’s (CBRT) monetary policy. Covering the period from 2002:1 to 2017:8 it also explores possible nonlinearities in the reaction function of the CBRT by employing a Threshold Vector Autoregressive (TVAR) model. The linear estimation of the model highlighted the importance of the exchange rate in monetary policy under IT. The results of the nonlinear model indicate that the stance of monetary policy was asymmetric with respect to exchange rate movements during the conventional IT period. However, the asymmetric monetary policy stance disappeared in the aftermath of the Global Financial Crisis. Increasing considerations of financial stability undermined the asymmetric policy stance of the CBRT in the post-crisis period.     

Beyond Brenner's investment overhang hypothesis: the case of the steel industry

This article challenges the way liberal economic governance has come to be theorised as a passive and depoliticised form of governance. Using the classic case of the gold standard, it shows how state intervention came to be shaped by considerations of state power and diverged considerably from the traditional emphasis on free markets and stable conditions of investments. As I argue, the gold standard was constructed through political struggles over monetary governance which involved significant constraints for capitalist investors. Its institutions helped establish a new structure for exerting control over finance. By resituating the gold standard in a broader historical perspective, I show how nineteenth-century monetary governance, far from leading to a retreat of the state, established in fact the foundations of a new form of state intervention: modern central banking.     

Cumulant instrument estimators for hedge fund return models with errors in variables

We revisit the factors incorporated in asset pricing models following the recent developments in financial markets – i.e., the rise of shadow banking and the change in the transmission channel of monetary policy. We propose two versions of the Fung and Hsieh (2004) hedge fund return model, especially an augmented market model which accounts for the new dynamics of financial markets and the procyclicality of hedge fund returns. We run these models with an innovative Hausman procedure, tackling the measurement errors embedded in the models factor loadings. Our empirical method also allows for confronting the drawbacks of the instruments used to estimate hedge fund asset pricing models.     

Bank Deregulation, Supervision, and Agency Problems

This article argues that the financial instability of the 1980s following financial deregulation in Australia can be partly traced to a lack of attention to agency problems in banking. Because the market for corporate control and corporate governance structures in banking were unsatisfactory, the benefits of increased competition in financial product markets were offset by inadequate monitoring and controls on bank management. It is also argued that the current emphasis of prudential supervision on capital adequacy requirements can provide only a partial solution to achieving efficiency and stability in the financial sector—because it focuses only upon the agency relationships between owners and government/depositors. Complementary developments in corporate governance and control are required to address agency relationships involving bank management. Some recent developments in this area and in supervision of non-bank financial markets are assessed from the perspective developed in this article.     

预期管理理论的形成、演变与启示

本文从货币政策视角梳理了预期管理理论的形成与演变历程,探讨了对通胀预期管理的现实启示。本文研究发现,预期管理理论以货币政策可信度为核心,历经从规则与相机抉择之间的摇摆到融合政策承诺与中央银行沟通并形成前瞻性引导的过程,各种预期管理思想的引入均通过对货币政策施加各种约束,促进政策的动态一致性,提高公众预期形成的精确性。构建以新凯恩斯主义DSGE模型为基础的预期管理框架,改进以预期形成机制和金融体系的模型化为代表的模型结构,采用机制设计方法完善货币政策框架成为未来预期管理理论发展的重要方向。对于我国而言,加快以利率与汇率市场化改革为代表的金融改革,强化以价格稳定为核心的货币政策调控,并通过有效权衡稳增长、调结构与反通胀之间关系,塑造坚定的反通胀立场,形成以通胀目标为代表的名义锚。同时构造兼顾价格稳定与金融稳定的宏观审慎管理框架和中国特色的新凯恩斯主义DSGE模型,提高预期管理的可信度。     

European policy and markets: Did policy initiatives stem the sovereign debt crisis in the euro area?

We investigate how European policy initiatives influenced market assessments of sovereign default risk and banking sector fragility during the sovereign debt crisis in four adversely affected countries — Portugal, Ireland, Spain and Italy. We focus on three broad groups of policies: (a) ECB policy actions (monetary and financial support), (b) EU programs (financial and fiscal rules as well as financial support in crisis countries), and (c) domestic austerity programs. We measure immediate market impact effects: what policies changed risk perceptions, using CDS spreads on sovereign bonds and banks in this assessment. We employ dynamic panel and event study methodologies in the empirical work. We find that a number of programs initially stabilized sovereign and bank bond markets (e.g. Outright Monetary Transactions program), although announcement and implementation impacts on markets differed in some cases (e.g. second Covered Market Bond Program). Actions designed to shore up sovereign markets often lowered risk assessments in bank bond markets and policies designed to ensure safety and soundness of the European banking system in some cases significantly impacted sovereign debt markets. Finally, a number of policies designed to stabilize markets had surprisingly little immediate impact on either sovereign or bank bond market risk assessments.     

控风险与稳增长挤压下的中国货币政策*

当前“名稳实紧”的货币政策已经不能适应我国宏观经济现状,货币政策总体思路亟待调整。过高的债务率所导致的债务-紧缩效应以及目前市场上所采取的“杠杆率硬着陆”的方式不仅加剧了金融市场的潜在系统性风险,而且还导致货币政策陷入传导困境。金融市场上财务软约束、刚性兑付现象大量存在,抬高了无风险利率,而且导致市场丧失风险定价功能。基于上述分析,我们认为当前货币政策取向应该从“名稳实紧”调整为“适度宽松”。在“杠杆率软着陆”的思路下,通过创新货币政策目标,配合市场化改革,尝试探索新型货币政策工具并结合市场监管体系的完善,早日实现经济复苏。     

Nonlinear monetary policy reaction functions in large emerging economies: the case of Brazil and China

This article estimates monetary policy rules for two key emerging market economies: Brazil and China. It analyses whether the monetary authority reacts to changes in economic activity, financial markets, monetary conditions, the foreign exchange market and the commodity price. We assess the importance of nonlinearity using a smooth transition regression (STR) model. Using quarterly data over the time period 1990:1 to 2008:4, we find that considerations about the output gap and the real effective exchange rate (in the case of Brazil), and the inflation rate (for China) explain the nonlinear adjustment of the central bank rate. Moreover, the results suggest that central banks pursue a target range for the threshold variable rather than a specific point target. In the case of China, the McCallum rule shows that the GDP growth, the interest rate and the commodity price drive the response of the growth rate of the relevant monetary aggregate.
