Financial stress,sovereign debt and economic activity in industrialized countries: Evidence from dynamic threshold regressions

We analyze how the impact of a change in the sovereign debt-to-GDP ratio on economic growth depends on the level of debt, the stress level on the financial market and the membership in a monetary union. A dynamic growth model is put forward demonstrating that debt affects macroeconomic activity in a non-linear manner due to amplifications from the financial sector. Employing dynamic country-specific and dynamic panel threshold regression methods, we study the non-linear relation between the growth rate and the debt-to-GDP ratio using quarterly data for sixteen industrialized countries for the period 1981Q1-2013Q2. We find that the debt-to-GDP ratio has impaired economic growth primarily during times of high financial stress and only for countries of the European Monetary Union and not for the stand-alone countries in our sample. A high debt-to-GDP ratio by itself does not seem to necessarily negatively affect growth if financial markets are calm.     

房价调控、地方政府债务与宏观经济波动

在地方政府债务高企的背景下,房价调控能否使资本流向非房地产部门？房价调控如果触发地方政府债务违约,宏观政策应如何应对？本文基于中国宏观经济的特征事实,引入地方政府的土地财政行为,将房价变动与地方政府的偿债能力联系起来。研究表明,由于地方政府依赖土地出让和土地抵押贷款筹集收入,房价管控导致的地价下降会带来地方政府收入的下降,直接影响地方政府的偿债能力。如果地方政府债务不出现违约,那么房价管控带来的地价下降会降低地方政府从金融部门获得的抵押融资额,使非基建部门的融资成本下降,非基建部门投资和产出上升。而如果调控房价带来的地价下降导致地方政府出现债务违约,金融部门资产受损,使金融中介减少贷款和提高贷款成本,带来整个社会的信贷紧缩,经济中各个部门的产出大幅下降。进一步的政策分析表明,有必要在避免地方政府债务违约的同时,使用财政资金补充银行资本金等多种方式稳定金融中介的资产负债表,从而将房价调控对经济的负面影响程度降到最低。     

美国经济各部门的负债水平及发展趋势

宏观部门的负债水平与金融市场的发展程度及经济周期高度相关,也是衡量金融风险的重要指标之一。文章用负债／收入（GDP）这一指标来考察美国经济各部门（家庭、企业、金融机构与政府部门）相对负债水平的历史和现状,并对其发展趋势做出初步研判,指出一国债务水平有长期上升的趋势,美国“去杠杆”化过程已降低了私人部门风险,但政府财政风险值得关注。     

Institutions,banking structure and the cost of debt: new international evidence

This paper analyses the effect of institutions and the structure of the banking system on the cost of debt for a sample of firms from 37 countries. The cost of debt decreases with the rule of law, the protection of creditors’ rights and the weight of banks in the economy. Bank financing and bank concentration have a positive differential effect on the cost of debt in those countries where the financial difficulties of banks are greater. Legal enforcement, the protection of creditors’ rights and the weight of bank financing have a greater influence in countries with a lower degree of economic development.     

金融生态环境、审计意见与债务融资成本

本文旨在研究金融生态环境、审计意见对于上市公司债务融资成本的影响。以2006—2009年1555家中国A股上市公司为样本,实证发现,良好的金融生态环境有助于上市公司获得较低成本的债务融资,民营上市公司承担了比国有上市公司显著更高的债务融资成本,而金融生态环境的改善有助于降低这种信贷融资成本差异。同时,被出具非标审计意见的上市公司相比获得标准审计意见的上市公司具有显著更高的债务融资成本,并且无论是对国有企业抑或民营企业来说,良好的金融生态环境都有助于增强审计意见的风险揭示功能。研究结果表明,在我国良好的金融生态环境以及外部审计监督有助于增强债务融资的市场化定价,提高信贷资源的配置效率。     

Measuring financial stress in transition economies

This study constructs a financial stress index for Bulgaria, the Czech Republic, Hungary, Poland, and Russia and examines the relationship between financial stress and economic activity. The financial stress index incorporates banking sector fragility, time varying stock market return volatility, sovereign debt spreads, an exchange market pressure index, and trade credit. These variables seem to capture key aspects of financial stress in sample countries as the index peaks at known financial crises in these countries. We then examine the relationship between financial stress and economic activity. Impulse response functions based on bivariate VARs show a significant relationship between financial stress and some measures of economic activity. Overall, the constructed financial stress index provides valuable information on the state of the economy and economic activity.     

中国家庭偿债能力:衡量与影响因素

居民部门债务的快速增长和过度累积可能导致经济体系产生潜在的金融风险。本文以2011-2017年中国家庭金融调查(CHFS)数据为研究样本,选取了综合衡量家庭偿债能力的指标,并根据宏观层面的不良贷款率对该指标进行校准。进一步地,本文基于衡量结果分析了我国家庭偿债能力的影响因素。研究发现:第一,2011-2017年期间我国金融脆弱性家庭占比呈逐年上升趋势,且现阶段我国金融脆弱性家庭变动状况存在明显的人群异质性和地区异质性。应警惕居民部门杠杆率过快上升的透支效应和潜在风险,关注低收入家庭的偿债风险。第二,购房预期收益上升使家庭产生加杠杆行为,导致家庭过度负债从而使家庭偿债能力进一步恶化。本研究对我国居民部门的金融风险监测、评估和预警有一定启示。     

Sovereign debt markets in turbulent times: Creditor discrimination and crowding-out effects

In 2007, countries in the euro zone periphery were enjoying stable growth, low deficits, and low spreads. Then the financial crisis erupted and pushed them into deep recessions, raising their deficits and debt levels. By 2010, they were facing severe debt problems. Spreads increased and, surprisingly, so did the share of the debt held by domestic creditors. Credit was reallocated from the private sector to the public sector, reducing investment and deepening the recessions even further. To account for these facts, we propose a simple model of sovereign risk in which debt can be traded in secondary markets. The model has two key ingredients: creditor discrimination and crowding-out effects. Creditor discrimination arises because, in turbulent times, sovereign debt offers a higher expected return to domestic creditors than to foreign ones. This provides incentives for domestic purchases of debt. Crowding-out effects arise because private borrowing is limited by financial frictions. This implies that domestic debt purchases displace productive investment. The model shows that these purchases reduce growth and welfare, and may lead to self-fulfilling crises. It also shows how crowding-out effects can be transmitted to other countries in the euro zone, and how they may be addressed by policies at the European level.     

Private sector share of external debt and financial stability: Evidence from bank loans

In the last two decades, the private sector has contracted a substantially larger share in the total amount of foreign-currency international debt (private sector share of external debt), especially in developing countries. In this paper, I empirically examine the effect of this phenomenon on bank loan prices. I find that the private sector share of external debt negatively and significantly impacts the price of bank loans. This result supports the hypothesis that private sector debt contributes to international financial stability to a greater degree than sovereign debt. Nevertheless, this impact is canceled out in the presence of fixed exchange regimes that are unsuitable with respect to fundamentals. In such circumstances, the private sector may take advantage of capital market distortions that are maintained by official authorities and thus exposes the country to further financial instability. Additional results corroborate the observation that the gain in financial stability stems from more efficient use of funds and reduced monitoring costs.     

Investments,Credit, and Corporate Financial Distress: Evidence from Central and Eastern Europe

Although they are instrumental for economic development, productivity-enhancing corporate investments may increase the financial vulnerability of companies, especially in an economic and financial crisis. We employ an instrumental probit model with the aim of finding evidence for the investment and credit patterns that led companies into financial distress during the global financial crisis 2009–2010. The company-level micro-data for our study on three Central and East European countries—Hungary, Bulgaria, Romania and two Baltic countries, Latvia and Lithuania—originates from two independent surveys, the Business Environment and Enterprise Performance Survey conducted in 2008 and the Financial Crisis Survey conducted in 2009/2010. Both were carried out jointly by the EBRD and the World Bank. Our results emphasize a substantial adverse impact from investment intensity and debt financing on company financial soundness during a crisis. On top of that, we discover a strong non-linear pattern in the sensitivity of company distress to its investment-financing nexus.     

当前国际政府债务问题的影响与警示

为应对席卷全球的国际金融危机,各国政府纷纷采取经济刺激措施,代替民间企业和金融机构承担危机成本,这不可避免带来一定的政府债务问题。随着时间的推移,部分政府债务问题逐步凸显,成为全球经济走出危机阴影的障碍。文章分析认为,当前国际上政府债务问题呈现脆弱性、复杂性、集中性和长期性特征,成为全球经济复苏的绊脚石,甚至会给世界各国经济带来灾难性影响。文章同时总结了国际政府债务问题带给我国的启示。     

主权债务风险跨国溢出研究——来自频域的新证据

本文从国家间主权债务风险溢出的持续期角度出发,采用基于广义方差分解谱表示的BK溢出指数方法,首次从频域视角对短期和长期下的主权债务风险跨国溢出效应进行研究。研究发现:第一,短期和长期下的主权债务风险跨国溢出效应均较为显著,并且时域下的总溢出主要由短期的风险溢出主导。第二,14个国家的短期和长期风险输出水平呈线性关系,但对于风险输入,不同类型国家出现分化并形成两个聚类,新兴市场国家的短期风险输入水平远高于长期,其具有较强的“短期脆弱性”。第三,风险输出国的自身风险越大,对他国的长期溢出水平越高,风险输入国的自身风险越大,接收他国的短期溢出水平越高,并且两两国家间的进出口规模、金融市场一体化水平和经济周期协同性与其长期风险溢出水平呈正相关关系,而与其短期风险溢出水平的关系并不显著。第四,短期和长期的主权债务风险溢出网络都呈现明显的区域聚集特征,并且各国在短期溢出网络中主要与同区域以及经济金融环境相似的国家连接,在长期溢出网络中则通过经贸关系将连接范围扩大至不同区域甚至经济金融环境差异较大的国家。     

A Conference on Postcrisis Banking

This article provides an introduction to the special issue. We focus on four themes that are important for policymakers and researchers alike in view of the experiences of the global financial crisis of 2007–09 and the ensuing sovereign debt crisis in the euro area: the relevance of the banking sector for the real economy, the future structure and regulation of the banking sector, the efficacy of past and current regulatory reforms, and the impact of cross‐border banking on economic stability and financial development.

The Effects of Corporate and Country Sustainability Characteristics on The Cost of Debt: An International Investigation

We investigate the relationship between corporate and country sustainability on the cost of bank loans. We look into 470 loan agreements signed between 2005 and 2012 with borrowers based in 28 different countries across the world and operating in all major industries. Our principal findings reveal that country sustainability, relating to both social and environmental frameworks, has a statistically and economically impactful effect on direct financing of economic activity. An increase of one unit in a country's sustainability score is associated with an average decrease in the cost of debt by 64 basis points. Our international analysis shows that the environmental dimension of a country's institutional framework is approximately twice as impactful as the social dimension, when it comes to determining the cost of corporate loans. On the other hand, we find no conclusive evidence that firm‐level sustainability influences the interest rates charged to borrowing firms by banks. Our main findings survive a battery of robustness tests and additional analyses concerning subsamples, alternative sustainability metrics and the effects of financial crisis.     

Firm Internationalization and Capital Structure in Developing Countries: The Role of Financial Development

We investigate the relationship between internationalization and the level of debt financing for more than 18,000 firm/year observations from thirty-one developing countries in the period 1991-2006. We argue that this relationship can be affected by both country-level and firm-level factors. The results show that in developing countries with relatively higher financial development, firm internationalization corresponds with a greater level of debt when firms have more growth opportunities (which also indicate a higher level of asymmetric information). This evidence suggests that relatively developed financial markets in developing countries at least partially mitigate the effect of asymmetric information and decrease the agency cost of debt for firms with higher levels of internationalization.     

Does sovereign risk matter? New evidence from eurozone corporate bond ratings and zero-volatility spreads

In this paper, we empirically examine if sovereign risk matters for corporate bonds in developed economies. Using a unique panel data sample of 897 corporate bonds from eleven countries within the Economic and Monetary Union (EMU), we investigate sovereign and corporate ratings as well as zero-volatility spreads (z-spreads). In the time period from March 2006 to June 2012, we find sovereign risk to be a significant driver of corporate risk. The effect is stronger for companies with domestic revenue structure, for companies that are (partly) owned by the government, and companies active in the utility and transportation sector. Interestingly, the impact of sovereign risk on corporate risk during the acute European sovereign debt crisis period decreases if ratings are examined, but increases if z-spreads are utilized. Rating agencies seem to take a more differentiated view on individual company risk during the sovereign debt crisis, while institutional investors might want to reduce their exposure to a country in financial distress as a whole, regardless of whether sovereign or corporate bonds are held.     

基于宏观资产负债表的居民债务问题及其风险研究

本文从宏观资产负债表的编制出发,对比世界主要经济体的居民债务演变,有效度量中国居民部门的债务杠杆水平。通过宏观部门经济间的关联,构造基于存量-流量一致的部门结构化均衡模型,剖析居民部门债务风险的传导机制,分析货币、财政和地产政策在居民债务风险防范中的作用。结果表明:中国居民部门金融资产负债率和偿债比例偏高,偿债压力逐步加大。但适中的资产负债率和较高的潜在经济增速为我国居民部门债务风险的化解提供了足够的空间。紧缩性货币政策有利于居民部门去杠杆化,但由此引发的消费减速和经济下行将导致企业和政府部门债务攀升;减税较政府直接支出更能激发消费内需、降低居民和企业债务杠杆,同时,长期经济的好转利于政府债务风险稳定。紧缩性地产政策虽然有助于长期经济结构的调整,但需防范短期经济下滑。     

主权评级对市场影响的实证分析

主权评级作为市场信息传递中介备受质疑。本文考察了目前欧洲债务危机中的主权评级,采用固定效应模型分别研究三大评级机构主权评级观察及评级降级对欧元区国家融资成本的市场影响。结果表明,主权评级对于市场长期影响不是很大,其中独立的降级影响不显著;评级负面观察的市场影响较评级降级的独立影响显著;评级观察及降级变化尽管对高级别国家的影响有限,但对A级以下的国家有明显的冲击影响。评级结果可能加剧了欧洲债务危机的解决难度。     

Trade Credit, Corporate Groups, and the Financing of Belgian Firms

We investigate the role of trade credit as a source of financing. Using a sample of 661 large non-financial Belgian firms for the 1989–1991 period, we find that the amount of trade credit a buyer takes is determined by his need for funds and the internally available funds. Trade credit is primarily used to finance short-term assets. As such, it seems to be an important alternative not only for short-term bank debt but also for long-term financial debt, including intragroup debt. We find no evidence that the amount of trade credit taken is influenced by affiliation with the supplier.
