Bank loans for private and public firms in a liquidity crunch

Bank reliance on short-term funding has increased over time. While an effective source of financing in good times, the 2007 financial crisis has exposed the vulnerability of banks and ultimately firms to such a liability structure. We show that banks dependent on wholesale funding contracted their lending the greatest during the crisis. Our results suggest, however, that in the financial crisis vulnerable banks passed the liquidity shock only to public firms and not to private firms. Loans to private firms were affected through a different channel, largely through higher retained shares by lead arrangers. Consistent with standard models of financial intermediation with information asymmetry, vulnerable banks increased their monitoring of informationally opaque firms for which the potential for informational rents is the highest.     

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.     

Finance and growth in a bank-based economy: Is it quantity or quality that matters?

Most finance–growth studies approximate the size of financial systems rather than the quality of intermediation to explain economic growth differentials. Furthermore, the neglect of systematic differences in cross-country studies could drive the result that finance matters. We suggest a measure of bank’s intermediation quality using bank-specific efficiency estimates and focus on the regions of one economy only: Germany. This quality measure has a significantly positive effect on growth. This result is robust to the exclusion of banks operating in multiple regions, controlling for the proximity of financial markets, when distinguishing different banking sectors active in Germany, and when excluding the structurally weaker East from the sample.     

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.

Dealing with financial instability under a DSGE modeling approach with banking intermediation: A predictability analysis versus TVP-VARs

In the dynamic stochastic general equilibrium (DSGE) literature there has been an increasing awareness on the role that the banking sector can play in macroeconomic activity. We present a DSGE model with financial intermediation as in Gertler and Karadi (2011). The estimation of shocks and of the structural parameters shows that time-variation should be crucial in any attempted empirical analysis. Since DSGE modelling usually fails to take into account inherent nonlinearities of the economy, we propose a novel time-varying parameter (TVP) state-space estimation method for VAR processes both for homoskedastic and heteroskedastic error structures. We conduct an exhaustive empirical exercise to compare the out-of-sample predictive performance of the estimated DSGE model with that of standard ARs, VARs, Bayesian VARs and TVP-VARs. We find that the TVP-VAR provides the best forecasting performance for the series of GDP and net worth of financial intermediaries for all steps-ahead, while the DSGE model outperforms the other specifications in forecasting inflation and the federal funds rate at shorter horizons.

Alternatives to blanket guarantees for containing a systemic crisis

This paper seeks to explain how policy actions undertaken at the outset of recent crises—particularly the issuance of extensive liquidity support and government guarantees—absorb off-budget fiscal resources and inappropriately constrain officials’ subsequent options for restructuring their country’s troubled financial and corporate sectors. Empirical evidence supports the commonsense view that the damage a crisis works on a country’s financial sector and on its real economy is lessened by taking market-mimicking actions that promptly estimate and allocate losses during the early stages of a crisis. The most important steps are to plan to call a timeout to separate hopelessly insolvent institutions from potentially viable ones and to provide haircuts, guarantees, and liquidity support in ways that protect taxpayers and avoid subsidizing insolvent institutions’ longshot gambles for resurrection.     

Bank capital shortfall in the euro area

We quantify the bank capital shortfall that results from a financial crisis by estimating a macro-finance dynamic stochastic general equilibrium model that captures the interactions between the financial and real sectors of the euro-area economy. The introduction of both deposit and shadow banks captures several characteristics of the banking system and reveals a financial amplification mechanism. By using a combination of a large positive risk shock and a large negative investment shock, we show that a crisis similar to that observed in 2008 would generate a bank capital shortfall between 2.2% and 3% of euro-area GDP, which corresponds to approximately 207–282 billion euros.     

Monetary policy and financial stability in a banking economy: Transmission mechanism and policy tradeoffs

The 2008 global financial crisis demonstrated that monetary policy and financial stability policy are more highly interrelated than previously thought. This paper analyzes the interactions between these policies using a non-linear overlapping-generations model with financial frictions in the form of banking financial intermediation. The paper embeds negative externalities due to contagion effects in physical investments which creates the need for financial stability policy. We show how the monetary policy transmission mechanism depends on financial stability policy tools as well as on regulatory and institutional constraints.We find policy tradeoffs in trying to accomplish both monetary and financial stability targets. The central bank must take these tradeoffs into account when selecting the tools in its policy toolbox. Another important finding is the interchangeability of price stability and financial stability policy tools.     

Does overcapacity prompt controlling shareholders to play a propping role for listed companies?

A major risk currently facing the Chinese economy is overcapacity, which affects the efficiency of social resource allocation (Xi et al., 2017; Huang et al., 2019). When a company is in crisis, the internal capital market often plays a propping role. This study approached this issue from the perspective of the controlling shareholder and examined whether controlling shareholders provide financial support to enterprises in industries with excess capacity. According to the data for China’s A-share listed companies from 2007 to 2019, companies in industries with excess capacity received more financial support from controlling shareholders compared with those in non-overcapacity industries. Analysis of the mechanism revealed that state-owned enterprises and companies with relatively poor financial status received more financial support from controlling shareholders. This study also examined the economic consequences of such support and found that it is conducive to enhancing enterprise value. This study enriches the literature on overcapacity and internal capital markets by demonstrating that internal capital markets play a propping role for companies facing industry-level crises. This finding has both theoretical value and practical implications related to supply-side reform and capacity reduction.     

现代金融中介理论视角下的我国金融体系模式选择

现代金融中介理论表明,商业银行等金融中介与经济增长之间存在密切的相关性。金融中介在促进经济增长的同时,也面临着许多复杂问题。本文从现代金融中介理论的视角出发,对银行导向型金融体系与市场导向型金融体系进行了国际比较,并从融资关系、风险管理、信息生产、公司治理等角度进行对比分析,得出在中国现实的环境下中介与市场发挥着不同作用,但金融中介的优势明显。因此,我国应选择以金融中介为主、资本市场为辅的金融体系,并加紧推出金融机构的混业经营模式。     

Macro-Networks: An application to euro area financial accounts

This paper develops a financial network, designated the “Macro-Network”, that depicts the connections between the main financial and non-financial sectors of the economy in the various financial instruments of the euro area. The Macro-Network comprises of linkages across financial and non-financial sectors in each country. These country-level sector networks are then connected by the cross-border links between the individual banking sectors. Using the Macro-Network to simulate financial shocks, we find that the propagation effects depend on the underlying network structure, which evolves over time. After the financial crisis, bilateral linkages contracted sharply, reflecting the surge in counterparty risk and the de-leveraging processes. Nonetheless, our analysis suggests that even after this process, vulnerabilities remained in the euro area financial system, while a more diversified portfolio of cross-border exposures might mitigate the shock effects. We identify sectors which are most relevant for the propagation of financial shocks in the Macro-Network.     

International transmission and business-cycle effects of financial stress

We analyze the international transmission of financial stress and its effects on global economic activity. Our analysis is based on country-specific monthly financial stress indices (FSIs) over the sample period 1970–2012 for 20 major economies. First, we show that co-movement between the FSIs increases during major financial crises and towards the end of our sample period. Second, we show that the risk of large financial stress spillovers to an economy increases with its level of economic openness. Third, we show – using a global VAR (GVAR) model – that (i) a financial stress shock in the US quickly transmits internationally, (ii) financial stress shocks have lagged but persistent negative effects on economic activity, and (iii) that a negative US demand shock induces only limited financial stress on a global scale. Finally, we show that spillovers of financial stress run mainly from advanced to emerging economies and not in the opposite direction.     

Financial crises,bank risk exposure and government financial policy

A macroeconomic model with financial intermediation is developed in which the intermediaries (banks) can issue outside equity as well as short term debt. This makes bank risk exposure an endogenous choice. The goal is to have a model that can not only capture a crisis when banks are highly vulnerable to risk, but can also account for why banks adopt such a risky balance sheet in the first place. We use the model to assess quantitatively how perceptions of fundamental risk and of government credit policy in a crisis affect the vulnerability of the financial system ex ante. We also study the effects of macro-prudential policies designed to offset the incentives for risk-taking.     

The determinants of vulnerability to the global financial crisis 2008 to 2009: Credit growth and other sources of risk

In this paper, we identify initial macroeconomic and financial market conditions that help explain the distinct response of the real economy of a particular country to the recent global financial crisis. Using four measures of crisis severity, we examine a data set with over 90 potential explanatory factors employing techniques that are robust to model uncertainty. Four findings are of particular note. First, we find empirical evidence for the pivotal role of pre-crisis credit growth in shaping the real economy's response to the crisis. Specifically, a 1% increase in pre-crisis lending translates into a 0.2% increase in the cumulative loss in real output. Moreover, the combination of pronounced growth in lending ahead of the crisis and the country's exposure to external funding from advanced economies is shown to intensify the real downturn. Economies with booming real activity before the crisis are found to be less resilient to the global shock. Buoyant growth in real GDP in parallel with strong growth of credit particularly exacerbated the effects of the recent crisis on the real economy. Finally, we provide empirical evidence on the importance of holding international reserves in explaining the response of the real economy to the crisis. The accumulation of international reserves mitigated the harmful effects of financial stress on the real economy, in particular when domestic funding via credit is abundant. The results are shown to be robust to several estimation techniques, including those allowing for cross-country spillovers.     

Financial instability contagion: a dynamical systems approach

We build a multi-agent dynamical system for the global economy to investigate and analyse financial crises. The agents are large aggregates of a subeconomy, and the global economy is a collection of subeconomies. We use well-known theories of dynamical systems to represent a financial crisis as propagation of a negative shock on wealth due the breakage of a financial equilibrium. We first extend the framework of the market instability indicator, an early warning signal defined for a single economy as the spectral radius of the Jacobian matrix of the wealth dynamical system. Then, we formulate a quantitative definition of instability contagion in terms thereof. Finally, we analyse the mechanism of instability contagion for both single and multiple economies. Our contribution is to provide a methodology to quantify and monitor the level of instability in sectors and stages of a structured global economic model and how it may propagate through its components.     

A model of unconventional monetary policy

We develop a quantitative monetary DSGE model with financial intermediaries that face endogenously determined balance sheet constraints. We then use the model to evaluate the effects of the central bank using unconventional monetary policy to combat a simulated financial crisis. We interpret unconventional monetary policy as expanding central bank credit intermediation to offset a disruption of private financial intermediation. Within our framework the central bank is less efficient than private intermediaries at making loans but it has the advantage of being able to elastically obtain funds by issuing riskless government debt. Unlike private intermediaries, it is not balance sheet constrained. During a crisis, the balance sheet constraints on private intermediaries tighten, raising the net benefits from central bank intermediation. These benefits may be substantial even if the zero lower bound constraint on the nominal interest rate is not binding. In the event this constraint is binding, though, these net benefits may be significantly enhanced.     

房价波动、金融稳定与最优宏观审慎政策

本文通过构建包含家庭住房抵押借款摩擦和银行贷款摩擦的动态随机一般均衡模型,重点考察了异质性冲击下房价波动对金融稳定的影响。研究发现,房价上涨会导致银行风险溢价及杠杆率显著上升,进而加剧金融体系的内在不稳定。为降低房价波动及维护金融稳定,选取两类宏观审慎政策工具进行逆周期调控实验,结果表明,在住房需求冲击下,金融管理部门应选取贷款价值比政策,且应对房贷积极调控,而对房价进行中性调控。在最终产品部门生产率冲击、房地产部门生产率冲击及跨期偏好冲击下,应选取资本充足率政策,但对房贷和房价调控力度的把握则存在差异。本研究为厘清房价波动对金融稳定的动态传导机制,以及金融管理部门如何选取宏观审慎政策工具以稳定房价并降低系统性金融风险提供了启示。     

重启资产证券化与我国的发展路径

传统金融监管不能有效应对资产证券化风险,是导致2008年次贷危机的主因。资产证券化在一国金融市场中占据重要地位,其发起-分流业务模式引发的风险需要金融监管者通过强化金融中介的激励机制和信息披露制度予以解决。美国已通过金融监管改革,在更安全、稳固的基础上重启资产证券化市场。我国有必要立足国情,完善试点法制和发挥自律组织的作用,重启并推广风险可控的资产证券化模式,以受益其功用和加快多层次资本市场的建设。
