Financial integration and business cycles in a small open economy

The purpose of this study is to examine a dynamic, stochastic, general equilibrium framework with financial and informational frictions and foreign borrowing in the case of money growth and technology shocks for a small open economy and to analyze the implications of varying degrees of financial integration for aggregate fluctuations and propagation mechanisms in the economy. The existence of informational asymmetries among the agents in the model necessitates financial intermediation in the economy. Moreover, there is uncertainty involved in the production process which leads to collateralized borrowing by firms and, therefore, has to be taken into account in the design of the loan contracts between firms and financial intermediaries. It is shown that increasing financial integration amplifies the effect of a positive, temporary monetary shock on output, consumption, investment, labor demand and loans; whereas it has barely any implication for the impact of a positive, temporary technology shock on the economy.     

人力资本偏向金融部门如何影响实体经济增长？

通过构建一个包含银行和生产性企业的两部门增长模型,本文系统考察人力资本偏向金融部门如何影响实体经济增长,并利用2008年中国经济普查数据、2003-2015年地级市数据及2011-2013年中国工业企业数据开展实证检验。理论分析表明,人力资本在金融部门与实体部门之间的配置结构对实体经济增长存在两种效应,依次为资本“挤入”效应和创新“挤出”效应,进而导致人力资本配置情况与实体经济增长率之间呈现倒“U”形关系。随后,计量结果为上述理论推断提供了系列经验证据,且机制检验证实人力资本配置到金融部门有助于促进信贷规模扩张。特别地,反事实框架的测算结果显示,人力资本有效配置将提升实体经济增长率约0.45%,而且贡献率随经济发展更加凸显。本文结论表明,应理性看待人力资本向金融部门的不断聚集,不以简单线性关系进行判断,要综合权衡资本“挤入”效应和创新“挤出”效应的相对重要性。     

Credit risk transfer and financial sector stability

In this paper, we study credit risk transfer (CRT) in an economy with endogenous financing (by both banks and non-bank institutions). Our analysis suggests that the incentive of banks to transfer credit risk is aligned with the regulatory objective of improving stability, and so the recent development of credit derivative instruments is to be welcomed. Moreover, we find the transfer of credit risk from banks to non-banks to be more beneficial than CRT within the banking sector. Intuitively, this is because it allows for the shedding of aggregate risk which must otherwise remain within the relatively more fragile banking sector. Therefore, regulators should act to maximize the benefits from CRT by encouraging the development of instruments favorable to the cross-sectoral transfer of aggregate credit risk (including basket credit derivatives such as collateralized debt obligations). Finally, we derive the optimal regulatory stance for banks relative to non-bank financial institutions. We show that a level playing field approach is sub-optimal. Regulatory stances should be set to actively encourage cross-sector CRT, first because of the higher fragility of the banking sector and second to induce banks to incur the costs of CRT which otherwise lead them to undertake an insufficient amount of CRT.     

Financial frictions on capital allocation: A transmission mechanism of TFP fluctuations

This paper provides a theory of financial frictions as a transmission mechanism for news shocks to drive aggregate TFP fluctuations. We show that in an economy calibrated to U.S. data, variations in financial frictions on capital allocation in response to news about future technology can generate aggregate TFP fluctuations and, thus, trigger business cycles before the actual technological change is realized. Using the COMPUSTAT dataset, we find that the relative capital productivity of financially constrained to unconstrained firms is highly countercyclical. Moreover, our VAR analysis shows that news shocks can account for a substantial fraction of the relative capital productivity fluctuations over business cycle frequencies.     

中国实业部门金融化的异质性

本文基于实业和金融两类投资组合模型的构建,重点考察不同所有权性质和不同行业企业的金融化驱动机制是否具有异质性,并探究不同类别金融投资对应结果的差异性特征。实证结果与已有研究以及传统印象并不一致:我们发现,风险规避是中国非国有企业和制造业企业金融化的显著驱动因素,而国有企业和非制造业企业则不存在这一特征;同时,非制造业企业的金融投资主要由收益率差驱动,而在其他企业样本中均没有证据显示追逐利润是企业金融化的推动因素。不同企业样本的融资约束、杠杆率、成长性、流动性水平以及资产质量等因素对企业金融资产占比的影响也存在显著差异。进一步区分企业金融投资中货币和非货币类金融资产的不同特性并考虑企业的长期股权投资,结果表明货币类金融资产和非货币类金融资产的驱动机制存在明显差异:对于货币类金融资产投资,国有企业主要受资本逐利因素推动,其他企业则未体现这一特征;对于非货币类金融资产投资,非国有企业、制造业和非制造业企业均受到风险因素驱动,而国有企业则不受影响;将企业长期股权投资纳入金融资产后结果则未产生明显差异。     

Monetary policy and financial (in)stability: An integrated micro–macro approach

Evidence on central banks’ twin objective, monetary and financial stability, is scarce. We suggest an integrated micro–macro approach with two core virtues. First, we measure financial stability directly at the bank level as the probability of distress. Second, we integrate a microeconomic hazard model for bank distress and a standard macroeconomic model. The advantage of this approach is to incorporate micro information, to allow for non-linearities and to permit general feedback effects between financial distress and the real economy. We base the analysis on German bank and macro data between 1995 and 2004. Our results confirm the existence of a trade-off between monetary and financial stability. An unexpected tightening of monetary policy increases the probability of distress. This effect disappears when neglecting microeffects and non-linearities, underlining their importance. Distress responses are largest for small cooperative banks, weak distress events, and at times when capitalization is low. An important policy implication is that the separation of financial supervision and monetary policy requires close collaboration among members in the European System of Central Banks and national bank supervisors.     

Identifying systemically important financial institutions in Turkey

This paper examines the systemic risk of financial firms in Turkey. Using Component Expected Shortfall, we provide estimates of systemic risk in Turkey using daily data from 2005 to 2018 and a comprehensive data set encompassing 54 financial firms. Empirical results show that the preponderance of systemic risk in the sample in Turkey is due to large commercial banks. Top ten systemically important financial institutions dominate systemic risk measures in Turkey and account for more than 90 % of total risk over the sample. Consequently, the risk in the Turkish financial system is concentrated in specific financial institutions and makes close monitoring of the top firms essential. Historical incidence of systemic risk in the sample shows elevated levels of systemic risk correspond to well-known external events. Finally, a bivariate VAR model shows that systemic risk is correlated with measures of global financial risks and has significant negative effects on the real economy particularly on industrial production. This is important from a financial stability point of view in that close monitoring of the systemic risk is important in maintaining a healthy financial system and a well- functioning market economy.     

金融错配、非金融企业影子银行化与经济“脱实向虚”

当前,我国一些非金融企业通过直接或间接的方式从事影子银行业务。本文利用2004-2015年上市公司数据研究发现,金融错配程度的提高整体上会提高企业影子银行化规模,并且这种效应仅在金融深化程度较高、经济资源市场化配置程度偏低的地区显著;僵尸企业和盈利性较差的企业,分别受到"利润追逐"和"投资替代"机制的影响,金融错配对其影子银行化趋势的正向作用更为明显。机制检验发现,金融错配水平的上升通过提高融资约束程度从而降低企业实体投资水平,这种效应在资产专用性较强的企业中更为明显;金融错配主要通过融资约束程度和实体投资规模,而非资本回报率渠道作用于企业影子银行化行为。本文研究对于提高信贷资源配置效率,防范经济"脱实向虚"具有较强的政策意义。

后金融危机时期的金融创新策略与风险监管

金融创新与金融风险两者之间是一种相互促进、相互发展的关系。金融创新在为转移和分散金融风险做出了巨大贡献的同时也带来了新的风险。后金融危机时期我们不能停止金融创新的步伐,但一方面应注意处理好虚拟经济与实体经济的关系、处理好市场导向与加强监管的关系、处理好交易所市场与场外市场的关系;另一方面应通过实施有效的监管安排来防范和化解市场的宏观风险。     

Is more finance better? Disentangling intermediation and size effects of financial systems

Financial systems all over the world have grown dramatically over recent decades. But is more finance necessarily better? And what concept of financial system – a focus on its size, including both intermediation and other auxiliary “non-intermediation” activities, or a focus on traditional intermediation activity – is relevant for its impact on real sector outcomes? This paper assesses the relationship between the size of the financial system and intermediation, on the one hand, and GDP per capita growth and growth volatility, on the other hand. Based on a sample of 77 countries for the period 1980–2007, we find that intermediation activities increase growth and reduce volatility in the long run. An expansion of the financial sectors along other dimensions has no long-run effect on real sector outcomes. Over shorter time horizons a large financial sector stimulates growth at the cost of higher volatility in high-income countries. Intermediation activities stabilize the economy in the medium run especially in low-income countries. As this is an initial exploration of the link between financial system indicators and growth and volatility, we focus on OLS regressions, leaving issues of endogeneity and omitted variable biases for future research.     

Bank capital and economic activity

Banks argue that holding higher capital will have adverse implications on their lending activities and thereby on economic growth. Yet, the effect of a stronger capital base on economic growth remains largely unsettled. We argue that better capitalized banks improve financial stability conditions and, in dire times, they are able to sustain credit to the economy thereby containing adverse macroeconomic implications. Using various methods, we test for the presence and strength of a financial stability channel and a bank lending channel by drawing evidence from 47 advanced and developing countries over close to two decades. We find that higher capital ratios improve financial stability and help sustain bank lending, ultimately exerting a positive influence on economic activity. These effects on real GDP growth are economically significant, reaching up to 1¼ percentage points for each percentage point acceleration in capital. Our main results are robust to various sensitivity checks, supporting the conclusion that safer banking systems do not bridle economic activity.     

金融周期对房地产价格的影响——基于SV-TVP-VAR模型的实证研究

本文利用2004-2016年的季度数据构建金融周期综合指数,用以描述金融市场景气程度;使用SV-TVP-VAR模型,围绕金融周期对我国房地产价格的影响进行实证研究。结果表明,金融周期对房地产价格的影响具有明显的时变性特征:2008年以前金融市场繁荣对房价有稳定推升作用,2008年后该影响持续弱化;与之类似,实体经济对房价的影响同样自2008年起逐渐减小。这意味着,在经济增长方式转变和经济结构调整的过程中,我国房地产价格对经济金融冲击的敏感度已经大幅下降,金融扩张可能难以再通过房地产市场有效带动实体经济的繁荣,相反,其反而可能导致银行贷款不良率的攀升,在金融系统内积累系统性风险。我国针对房地产的宏观调控政策不仅对控制贷款不良率的提高体现出积极作用,而且自2008年国际金融危机以来,产出及房价的随机波动率均呈显著下降趋势,风险得到有效控制。未来应更加重视房地产市场调控在宏观审慎政策框架中的重要地位,遏制房地产金融化泡沫化势头,防范房地产市场引发金融危机。     

实体杠杆对经济增长的影响研究——基于金融稳定的调节效应

本文以全球43个国家和地区2001-2020年的动态面板数据为研究样本,实证检验不同实体部门杠杆对经济增长的影响差异及作用机制。通过构造金融稳定指数,进一步论证金融稳定对实体杠杆与经济增长之间关系的调节效应。结果表明:实体杠杆与经济增长之间存在“倒U形”关系,不同部门杠杆对经济增长影响的“拐点”有所不同。机制检验发现,居民杠杆、企业杠杆和政府杠杆分别通过“消费”“投资”和“政府支出”渠道影响经济增长;金融稳定性的提升能够正向调节实体杠杆对经济增长的影响,提高实体杠杆对经济增长影响的“拐点”。上述结论对我国经济增长和杠杆调控具有一定政策启示。在经济运行过程中,应充分考虑各部门杠杆异质性,细化实体杠杆的调控方向,进一步优化杠杆结构,以期实现经济增长与金融稳定双重目标下的动态平衡。     

International capital flows and the boom-bust cycle in Spain

We study the joint dynamics of foreign capital flows and real activity during the recent boom-bust cycle of the Spanish economy, using a three-country New Keynesian model with credit-constrained households and firms, a construction sector and a government. We estimate the model using 1995Q1-2013Q2 data for Spain, the rest of the Euro Area (REA) and the rest of the world. We show that falling risk premia on Spanish housing and non-residential capital, a loosening of collateral constraints for Spanish households and firms, as well as a fall in the interest rate spread between Spain and the REA fuelled the Spanish output boom and the persistent rise in foreign capital flows to Spain, before the global financial crisis. During and after the global financial crisis, falling house prices, and a tightening of collateral constraints for Spanish borrowers contributed to a sharp reduction in capital inflows, and to the persistent slump in Spanish real activity. The credit crunch was especially pronounced for Spanish households; firm credit constraints tightened later and more gradually, and contributed much less to the slump.

金融同业活动与实体企业经营风险——来自地区层面同业存单业务的证据

本文研究了地区层面金融同业活动对实体企业经营风险的影响。基于各省份金融机构开启同业存单业务的研究表明,地区层面金融同业活动显著提升了当地上市企业股价大幅下跌的风险。进一步研究表明,随着同业存单业务的发展,当地上市企业债务融资成本和风险水平有所上升,而业绩表现和市场价值有所下降。上述发现表明,企业融资链条变长后,信贷市场道德风险上升,部分企业因风险偏好增强导致经营风险上升,更容易突然出现负面事件而导致股价大幅下跌。本文的发现揭示了金融同业活动存在监管规避的可能性及其影响实体企业的潜在路径,凸显了完善金融监管以更好服务实体经济发展的重要现实意义。

Relevance of Differences between Net Income based on IFRS and Domestic Standards for European Firms

Net income adjustments resulting from mandatory 2005 IFRS adoption in Europe are value relevant for financial and non‐financial firms. Differences in relevance of the aggregate adjustment and adjustments related to several IFRS standards, for financial and non‐financial firms and across country groups, suggest differences in domestic standards and institutions affect investors’ assessment of the relevance of IFRS accounting amounts. Despite these differences, except for French/German non‐financial firms, investors view net income measured using IAS 39 Financial Instruments: Recognition and Measurement as more relevant than that measured using domestic standards, which is notable because IAS 39 was highly controversial in Europe.     

Financial frictions and real implications of macroprudential policies

I model a number of imperfections in financial intermediation that have implications for real economic activity in a production economy with technological risk. Partially opaque firms are financed by both debt and insider equity. Banks have market power over borrowers. There can be a prior bias in public beliefs about aggregate productivity (business sentiment). I investigate the dependence of equilibrium on the biased business sentiment and a prudential policy instrument (a convex dependence of bank capital requirements on the quantity of uncollateralized credit). Loss given default can be reduced by both a monetary restriction and a macroprudential restriction. Real implications of both are very similar in the aggregate, but macroprudential policies are more advantageous for bank earnings. On the other hand, the policies considered here are unable to reduce the number of defaulting firms (default frequency). Economic activity is highly sensitive to ??leaning against the wind?? actions on both fronts, so that using a macroprudential instrument to intervene against an asset price bubble has tangible welfare costs comparable to those of a monetary restriction. The costs can be offset by fine tuning capital charges as a function of corporate governance on the borrower side (specifically, by discouraging limited liability of borrowing firm managers).
