Bank–firm relations and the role of Mutual Guarantee Institutions at the peak of the crisis

We examine the role played by Mutual Guarantee Institutions (MGIs) in the lending policies undertaken by banks at the peak of the Great Crisis of 2007–2009. We address this issue by using a large database on Italian firms built from the credit files of UniCredit banking Group and focusing on small business. We provide an empirical analysis of the determinants of the probability that a borrowing firm will suffer financial tension and obtain two main innovative findings. First, we find that small firms supported by MGIs less likely experienced financial tensions even at that time of utmost financial stress. Second, our empirical evidence shows that MGIs played a signaling role beyond the simple provision of collateral. This latter finding suggests that the information provided by MGIs turned out to be key for bank–firm relations as scoring and rating systems – being typically based on pro-cyclical indicators – had become less informative during the crisis.     

Financial development,government ownership of banks and firm innovation

Using a newly-available World Bank survey of over 28,000 firms from 46 countries, we examine how financial development affects firm innovation around the world. We find that while stock market development significantly enhances firm innovation, banking sector development has mixed effects. We show that the latter result can be explained by different levels of government ownership of banks. Specifically, in countries with lower government ownership of banks, banking sector development significantly enhances firm innovation; while in countries with higher government ownership of banks, banking sector development has no significant or sometimes even significantly negative effects on firm innovation. Such negative effects are significantly stronger for smaller firms. The results are robust to various controls such as firms’ human capital and ownership structure, to estimations using instrumental variable techniques and alternative measures of firm innovation.     

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。

A closer look at financial development and income distribution

This paper analyzes the under-investigated relationship uniting financial development and income distribution. We use a novel approach taking into account for the first time the specific channels linking banks, capital markets and income inequality, the time-varying nature of the relationship, and reciprocal causality. We construct a set of annual indicators of banking and capital market size, robustness, efficiency and international integration. We then estimate the determinants of income distribution using a panel Bayesian structural vector autoregressive (SVAR) model, for a set of 49 countries over the 1994-2002 period. We uncover a significant causality running from financial sector development to income distribution. In addition, the banking sector seems to exert a stronger impact on inequality. Finally, the relationship appears to depend on the characteristics of the financial sector, rather than on its size.     

Banking market structure,liquidity needs,and industrial growth volatility

While the existing literature acknowledges the effect of banking structure on industrial growth as well as the effect of financial development on industrial growth and its volatility, we examine whether banking structure, given financial development, exerts any nontrivial effect on industrial growth volatility. We show that bank concentration magnifies industrial growth volatility, but reduces the volatility in sectors with higher external liquidity needs. The reduction in industrial growth volatility mostly reflects the smoothing in the volatility of real value added per firm growth. A variety of sensitivity checks show that our findings remain for different model specifications, banking market structure measures, liquidity need indicators, and omitted variables.     

Spillover effects of banking systemic risk on firms in China: A financial cycle analysis

This paper investigates the spillover effects of banking sector risk on firms in China and explores the risk transmission channels from the perspective of financial cycle. We use the banking risk-taking and systemic risk as the proxies of financial booms and busts. Our study yields four main findings. First, the banking risk-taking reduces firm risk in financial booms. Higher financing costs and constraints, larger firm size and financing scale, and state ownership inhibit the spillover effects. Second, the banking systemic risk increases firm risk during financial busts. Higher financing costs and constraints, larger firm size and financing scale, and state ownership facilitate the spillover effects. Third, the magnitudes of banking risk spillovers vary across industries, and this effect is more pronounced in the manufacturing industry. Fourth, bank risk-taking affects firm risk differently through various channels in different leading periods. When leading 1 to 3quarters, banking risk-taking reduces firm risk, and channel variables inhibit the spillover effects. However, when leading 4 to 8 quarters, the rising bank risk-taking eventually increases firm risk, and channel variables amplify its spillover effects. Our study offers important policy implications for risk assessment and mitigation in the Chinese loan market.     

Correlation and spillover effects between the US and international banking sectors: New evidence and implications for risk management

This paper quantitatively examines return transmission and volatility spillovers between banking sector stocks in the US and eight other countries by applying our newly extended VAR-DCC-MEGARCH-M model with asymmetric spillovers and Student-t or skew-t errors. Our investigations clarify almost unidirectional stock return transmission from the US banking sector to all other eight international banking sectors. In addition, we also uncover bidirectional volatility spillovers between the US and other eight international banking sector stocks, which are all tied to the leverage effect. Moreover, using the dynamic conditional variances and covariances from our extended model, we derive the time-varying optimal hedge ratios and optimal portfolio weights. These analyses reveal that, except for such extraordinary periods as during financial crises, we can hedge the US banking sector stocks with other international banking sector stocks, and that well-balanced portfolios of the US and other banking sector stocks are optimal. Furthermore, additional analysis using gold, silver, and platinum futures reveals that we can hedge international banking sector stocks with precious metal futures highly effectively, and that well-balanced portfolios of banking stocks and precious metals are optimal. Based on the results from our analyses, this paper derives many significant interpretations and implications for financial and systemic risk management.     

Capital account liberalization and income inequality

This article makes both a theoretical and an empirical contribution to the literature on financial liberalization and income inequality. In the first part, we develop a tractable model that features agents with varying investment abilities and a banking sector. There are two possible interventions to liberalize the banking sector: first, a reduction in reserve requirements, and, second, an increase in the amount of foreign funds that can be used to finance domestic loans. Financial liberalization leads to enhanced banking sector efficiency and adjustments in interest rates affecting income of investors and savers, and, therefore, income inequality. Theoretically, the impact of financial liberalization on income inequality is ambiguous. Yet, the model suggests that financial liberalization will improve income distribution in countries where financial depth is high. Our empirical estimates confirm this conditional effect. More precisely, the estimates suggest that capital account liberalization only tends to lower income inequality if the level of financial depth, as measured by private credit over GDP, exceeds 25 percent.     

Default Predictors in Retail Credit Scoring: Evidence from Czech Banking Data

Credit to the private sector has risen rapidly in European emerging markets, but its risk evaluation has been largely neglected. Using retail-loan banking data from the Czech Republic, we construct two credit risk models based on logistic regression and classification and regression trees. Both methods are comparably efficient and detect similar financial and socioeconomic variables as the key determinants of default behavior. We also construct a model without the most important financial variable (amount of resources), which performs very well. This way, we confirm significance of sociodemographic variables and link our results with specific issues characteristic to new EU members.     

Does interest rate and its volatility affect banking sector development? Empirical evidence from emerging market economies

This study investigates the relationship between interest rate, interest rate volatility, and banking sector development in 12 emerging market economies located around the world. For this purpose, panel data analysis was conducted using annual data from 1980 to 2014. In parallel to the financial development literature, which asserts that banking sector development, as a broad and complex concept, cannot be measured by a single indicator, this study adopts a set of measures of banking sector development. The empirical results reveal that while interest rate has a positive impact on all banking sector indicators, this relationship weakens at higher interest levels, showing a concave relationship between interest rate and banking sector development. In addition, the empirical results provide evidence that interest rate fluctuations have a negative impact on most banking sector development (BSD) indicators, suggesting that the banking sectors of emerging countries are vulnerable to interest rate risks. Furthermore, all measures of the banking sector indicators are positively affected by economic growth rates, while this association weakens at higher levels of income, confirming a nonlinear relationship. Thus, the results have important implications for policymakers in improving the banking system and promoting the economic growth of these emerging economies.     

Predicting banking distress in the EMEAP economies

This study develops a panel probit model to identify the leading indicators of banking distress and to estimate the banking distress probability for EMEAP economies. Macroeconomic fundamentals, currency crisis vulnerability, credit risks of banks and non-financial companies, asset price gaps, credit growth, and the occurrence of distress in other economies are found to be important leading indicators. The model is applied to stress test the Hong Kong banking sector. Simulation results suggest that compared with the period before the Asian financial crisis, the banking sector is currently more capable of withstanding shocks similar to those that occurred during the crisis.     

Stock market risk in the financial crisis

In this paper, we look at the effect of the financial crisis from an angle overlooked to date in the finance literature by investigating composition effects arising from the financial crisis. A composition effect is a change in the market risk of a sector that is caused not by a direct change in that sector but by a change in another sector that affects the composition of the stock market. In the paper we investigate the pre and during crisis market risk of the industrial, banking and utilities sectors. Amongst other results, we find a positive relationship across the G12 countries between the increase in the market risk of industrials during the crisis and both the pre-crisis market risk of the banking sector and the scale of the systemic crisis in a country. The six G12 countries that experienced a major systematic banking crisis are amongst the seven countries with the largest increases in the market risk for industrials. Results drawn from our detailed analysis using US data are consistent with these findings. Finally, we show how the results add to our understanding of the linkages between the financial and real sector and conclude that composition effects of the financial crisis could have a significant chilling effect on investment in industrials, which is in addition to the effect of other linkages already documented.     

Korean bank governance reform after the Asian financial crisis

We discuss corporate governance reforms in the Korean banking sector, which include reforms in board composition and executive compensation, implemented after the Asian financial crisis in 1997 and examine the stock market's response to the reforms. We find that the banking returns and volatilities became more Granger-causally prior to both KOSPI and finance sector returns after 1998. The announcements of banking governance reforms are generally associated with significant increases in banking sector stock returns. The KIF survey finds that board governance is considered essential in assessing the value of the firm. The participants in the McKinsey survey indicate that they are willing to pay a premium of 24% on average for firms with outstanding corporate governance systems.

Freeing Greece from capital controls: Were the restrictions enforced in time?

Recent developments in Greece have caused for the implementation of banking capital controls on the outflow of funds, a policy decision not uncommon, especially in emerging markets. However, the issues of the Greek economy, which seem to stem from the public sector but have been passed on to the banking sector, pose a unique challenge to researchers. In this paper, we employ VBanking, an object-oriented model for banking simulations to examine whether capital controls in Greece were enforced at the appropriate time. Additionally, we propose that the banking sector will not purge this regulation soon. Finally, we demonstrate the destructive effects of capital controls both on the financial system and on the real economy. We present the empirical results of our work, which suggest that the Greek authorities’ response to the deterioration of the banking sector was lagged.     

Financial Exposure and the International Transmission of Financial Shocks

This paper analyzes the transmission mechanism of banking sector shocks in an international real business cycle model with heterogeneous bank sizes. We examine to what extent the financial exposure of the banking sector affects the transmission of foreign banking sector shocks. In our model, the more exposed domestic banks are to the foreign economy via lending to foreign firms, the greater are the spillovers from foreign financial shocks to the home economy. The model highlights the role of openness to trade and the dynamics of the terms of trade in the international transmission mechanism of banking sector shocks: spillovers from foreign banking sector shocks are greater the more open the home economy is to trade and the less the terms of trade respond to foreign shocks.     

中国金融部门间系统性风险溢出的监测预警研究——基于下行和上行ΔCoES指标的实现与优化

为了对我国金融部门间的系统性风险溢出进行实时监测和有效预警,本文基于Adrian and Brunnermeier (2016) 的CoES指标构想,在左尾视角的基础上进一步引入右尾视角,构建下行和上行ΔCoES分别作为系统性风险的同期度量指标和前瞻预警指标,并提出了更为有效合理且同时适用于下行和上行ΔCoES的计算方法。本文一方面采用下行和上行ΔCoES对我国银行、证券、保险三个金融部门间的系统性风险溢出进行监测预警研究,另一方面还基于我国的经验数据检验上行和下行ΔCoES的性质。研究结果显示,我国金融部门间具有显著的系统性风险溢出效应,且三个部门间的风险溢出存在非对称性,银行部门是系统性风险的主要发送者,证券部门是系统性风险的主要接收者;三个部门两两间的风险溢出水平表现出明显的协同性和周期性,且上行的风险溢出水平高于下行。同时,基于我国的经验数据发现,上行ΔCoES对下行ΔCoES具有显著的先导性、前瞻性,上行ΔCoES可以作为系统性风险的前瞻预警指标。此外,下行ΔCoES能够引领ΔCoVaR和基于MES估计方法计算的短期ΔCoES指标,表明本文构建的下行ΔCoES实时性更强,更适合作为系统性风险的实时监测指标。     

Sell-side analysts’ career concerns during banking stresses

We propose a new approach to examine sell-side analysts’ career concerns by relating their forecast boldness to their employers’ news flows. Specifically, we use banking sector news to proxy for the severity of career concerns. Analysts follow more closely the consensus forecast when the prospects of the banking sector are negative (and vice versa). The effect is both economically and statistically significant after controlling for various firm, analyst, brokerage house, and forecasting characteristics, as well as sector and economy wide effects. The more established analysts, in terms of reputation and experience, are generally unaffected by banking sector news. In contrast, their less established peers tend to cluster their forecasts near the consensus after a sequence of negative news flows for banks. Collectively, our results support the notion that during banking stresses when job security is low analysts’ tendency to imitate others increases.     

How does greater bank competition affect borrower screening? Evidence from China's WTO entry

We analyze the relationship between greater bank competition and the screening of potential borrowers. Using a large sample of Chinese private firms and China's entry into the WTO as a unique setting leading to greater bank competition, we find the following. First, the sensitivity of bank credit to prior borrowing-firm performance increases after China's WTO entry. This sensitivity increase is greater in more bank-dependent industries and smaller in Chinese regions with greater financial sector development. Second, the increase in the sensitivity of bank credit to firm performance is much greater for state-owned firms compared to private firms. Third, the effect of bank credit on subsequent firm productivity and performance is greater for loans given after China's WTO entry compared to those given prior to WTO entry. Overall, the results of our empirical analysis suggest that the stringency of bank screening of borrowers in China increased with greater banking sector competition.
