Modeling Guarantees,Over-Indebtedness and Financial Crises in an Open Economy

This work develops a simple framework to analyse how financial intermediaries’ balance sheet problems combined with financial guarantees make an economy more vulnerable to financial crises. A ‘double default’ problem – that is, the default of financial intermediaries on their debt repayments and of the government on its guarantees to bailout intermediaries’ losses – is modelled in this study. The possibility of multiple equilibria, including a crisis equilibrium where the government is not able or willing to honor its guarantees towards the domestic financial sector, arises from the interplay of all the above elements: financial intermediaries’ level of indebtedness, government implicit guarantees and high-risk creditors’ lending. This work also produces predictions concerning the vulnerability to a financial crisis: multiple equilibria are possible only in certain ranges of the fundamentals.     

华尔街“欺诈门”事件对中国衍生品市场制度完善的意义

2010年4月6日,美国证券交易委员会以涉嫌欺诈投资者对高盛公司提起民事诉讼,4月29日,SEC将高盛案移交美国司法部提起刑事侦查。随后,SEC联手美国司法部对华尔街更多大投资银行和评级机构展开了更大范围的调查,华尔街因此陷入＂欺诈门＂事件,并经受着前所未有的信用危机。华尔街＂欺诈门＂事件对中国衍生品市场制度完善具有非常重要的启示和意义,包括衍生品市场金融监管与金融创新应该同步协调、完善信息披露制度、加强对经纪商的行为规范、加强衍生品市场参与企业的内控机制建设以及要建立多元化的违法违规行为处理机制。     

How has the financial crisis affected earnings management? A European study

The article aims to investigate whether and how in the European Union (EU), the burst of the 2008 financial crisis affected misrepresentation of financial information due to earnings management. By analysing a sample of 11 844 firm-year observations listed in the EU over the period 2006–2012, an event study methodology allows us to calculate and compare country-by-country abnormal accruals over the estimation period and over the event period. Our findings validate our research hypothesis and suggest a decrease of misrepresentation in the large majority of the European countries after the burst of the financial crisis. The results take part in the debate in the accounting literature about the change of earnings management over a financial crisis and have several implications for standard setters and regulators that could learn how the common incentives of entities to attract potential investors during a crisis could lead them to provide a high-quality financial reporting.     

Determinants of corporate default risk in China: The role of financial constraints

Corporate default risk can affect financial stability and the macroeconomy. However, the determinants of corporate default risk in China are not well defined in the literature. We address this issue by using a rich credit event dataset of 981 Chinese listed firms over the period 1998–2013 and study the factors that affect default risk. We demonstrate that leverage, liquidity, firm size are the key firm-specific factors in determining default risk in China, along with macroeconomic factors like interest rate and stock return. Moreover, ‘Too big to fail’ only applies to non-SOEs, as default risk of SOEs is not affected by the firm size. We further find that high liquidity fails to reduce firms default risk, because small-sized firms which are financially constrained have limited cash to prevent financial distress, whereas large firms with greater cash holdings are able to mitigate their default risk as they are unconstrained.     

基于可流动性资产负债表的我国政府债务风险研究

政府资产是政府债务顺利偿还的基础,当政府资产低于其负债时,政府债务将面临一定风险,因此基于政府资产负债的视角,本文结合中国实际首先编制了一个简化的政府"可流动性资产"负债表,然后,分析了1998—2008年我国政府仅考虑直接债务时的政府债务风险,并且对2009—2010年的政府债务风险进行了分析。研究表明,2003—2006年因外汇储备急剧增长使我国政府债务风险总体较小且比较稳定,但因金融危机的爆发,我国政府债务风险在此期间前后的两次金融危机中都比较大,金融危机对政府债务风险的影响显著。研究还表明,积极的财政政策对短期降低政府债务风险具有明显效果,且1997年亚洲金融危机和2007年美国次贷危机对我国政府债务风险的影响具有相似性,即金融危机爆发后的几年内政府债务风险会因积极的财政政策而经历"大—小—大"的变化过程。最后,通过引入政府或有债务,分析了具有或有债务时的政府债务风险。本文认为,只要我国政府的或有债务规模不超过24万亿元人民币,则我国的政府债务风险较小。     

Worldwide impact of IMF policies during the Asian crisis: who does the IMF help,creditors or crisis countries?

This paper examines the effects of International Monetary Fund (IMF) policy announcements on financial markets worldwide. We investigate reactions from stock, bond, foreign exchange and futures markets and banking and financial companies during the Asian crisis. We explore the impact of IMF bailouts not only on crisis countries, but also on main creditor countries. We study the impact of local governments’ and public responses in crisis countries to account for interaction between the IMF and local parties. We show IMF involvement and local governments’ co-operation actually helps crisis countries but not creditors. We show that in crisis countries, financial markets generally react unfavourably to their governments’ initial demands for IMF assistance, while compliance of the crisis countries with the IMF policy action is commonly perceived as good news. Financial markets in crisis countries react negatively to prolonged negotiations and government actions against IMF policy. Creditor countries’ financial markets are not responsive to IMF actions in crisis countries. We discuss policy implications of findings.     

Spillover effects of the 2008 financial crisis on NIE stock markets

This article estimates dynamic conditional correlations of stock returns across countries by using DCC–GARCH model and analyse spillover effects of the 2008 financial crisis on the NIE’s stock markets. The results show that there is no regime shift in mean equation of the correlation coefficient during the financial crisis. It may imply there are no mean spillover effects of the US financial crisis on the NIE’s stock markets. However, there are volatility spillover effects of the financial crisis sparked in 2008 from the US to the NIE’s markets.     

The Korean financial crisis and the soft budget constraint

A panel of Korean firms is used to test for the soft budget constraint (SBC) in bank lending before and after the 1997–1998 financial crisis. SBC is present if a firm can borrow from its bank despite being in financial distress, which we define by a low Altman's z-score. We find that prior to 1997 financially distressed firms were able to borrow while after the crisis their ability to borrow declined substantially. We also demonstrate that SBC was a significant factor in the firms’ propensity to default during the crisis.     

Markets contagion during financial crisis: A regime-switching approach

Within a Markov regime-switching VAR framework, we investigate the contagion effects among the stock market, real estate market, credit default market, and energy market covering the most recent financial crisis period when markets experience regime shifts. The results demonstrate that the watershed of regimes occurs around the start of the subprime crisis in 2007, after which the “risky” regime dominates the evolution of market chaos. During the financial crisis, excluding their own shocks, stock market shock and oil price shock are the main driving forces behind the credit default market and stock market variations, respectively. The energy market also appears to be more responsive to the stock market movements than the shocks originating from housing and credit markets. However, the impacts from the credit default market on the real estate market are not significant as expected.     

BANK COMPETITION AND FINANCIAL STABILITY: LIQUIDITY RISK PERSPECTIVE

We study whether competition affects banks' liquidity risk‐taking, which was at the heart of the 2008 financial crisis. We find that banks with greater market power take more liquidity risk, implying that decreased competition leads to financial fragility. During a financial crisis, however, the effect of market power on liquidity risk varies across bank size. Small banks with greater market power reduce liquidity risk while large banks with greater market power do not change their liquidity risk‐taking behavior. This suggests that enhanced charter values due to reduced competition lowers small banks' risk‐shifting incentives when their default risk significantly increases during a crisis.

Detroit’s Municipal Bankruptcy: Racialised Geographies of Austerity

ABSTRACT

Urban geographer Jamie Peck theorises austerity urbanism as a dominant state practice of financially ‘restructuring’ the fiscal agendas of local governments in order to reduce government budget deficits in times of economic recessions. This project seeks to investigate the role of race in the context of austerity urbanism in Detroit following the subprime mortgage crisis in 2008. What is clear is that subprime lending in Detroit was explicitly a raced event. Analysis of austerity politics in Detroit demonstrates that the city is clearly spatially divided along racialised lines. Black city pensioners, former public sector employees, and ‘deliquent taxpayers’ were blamed for Detroit’s municipal bankruptcy in narratives centering on their bloated and generous benefits during the city’s financial decline. The policy outcomes of austerity programmes during the city’s financial crisis impacted racialised, poor communities, specifically the outcomes of privatising the city’s water services that led to state-sanctioned water shut-offs. This paper explores the ways in which race figures in the causes (race-based credit redlining/subprime super-inclusion lending practices) in the way the crisis was narrated to wrongly apportion blame to the racialised poor and city pensioners, and in the effects of the crisis, where water shut-offs wrought punishment on the racialised poor.     

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.     

Modeling the dependence structure between default risk premium,equity return volatility and the jump risk: Evidence from a financial crisis

This paper investigates the dependence structure between default risk premium, equity return volatility and jump risk in the equity market before and during the subprime crisis. Using iTraxx CDS index spreads from Japanese and Australian markets, the paper models the different relationships that can exist in different ranges of behavior. We consider several Archimedean copula models with different tail dependence structures, namely, Gumbel, Clayton, Frank, AMH and Joe copulas. Although the dramatic change in the levels of the iTraxx CDS index, we find strong evidence that the dependence structure between CDS and stock market conditions is asymmetric and orienting toward the upper side. In addition, we find that the Japanese CDS market is more sensitive to the stock return volatility than the jump risk and the magnitude of this sensitivity is related to the market circumstances. However, Australian CDS market is more sensitive to the jump risk than stock return volatility before and during the financial crisis. This result has important implications for both global financial stability and default risk management. Specifically, the heterogeneity of markets, coupled with the diversity in the risk exposures cause the default risk premium and equity markets to exhibit different levels of sensitivity.     

Credit Chains and Mortgage Crises

Here I examine a production economy with a financial sector that contains multiple layers of credit. The latter constitute credit chains that include a simple mortgage market. The focus is on the nature and contagion properties of credit chains in an economy where the financial sector plays a real allocating role, and agents have a serious choice of whether to default on mortgages or not. Multiple equilibria with different rates of default are observed, due to the presence of strategic complementarities. A liquidity crunch is associated with higher rates of default that can trigger a financial crisis as well as constrain the purchase of production factors, leading to reductions in welfare, together with potentially serious effects on real economic activity with the potential of causing deep and widespread recessions.     

An unlikely Phoenix: The recovery of Argentina’s monetary and financial system from its ashes in the 2000s and its lessons

The study discusses the recovery of the Argentine financial system after the crisis of the so called convertibility regime of the 1990s. The Argentine macroeconomic regime established in 1991 and based on the hard peg of the peso to the dollar at a 1 to 1 parity ended in a multiple crisis in 2001–2. Beyond the default on the public debt, the crisis also involved the breakdown of the domestic financial system, and an almost complete isolation of the country from the international financial markets as a consequence of the default. Under such a deep crisis and the consequent uncertainty, the recovery of the solvency of the financial institutions was an almost insurmountable enterprise. However, with a gradualist approach (contrary to the advice of the International Monetary Fund) and a degree of “regulatory forbearance,” the financial and monetary authorities were able to recover the health of the financial system, which became much more resilient to shocks, even if its development has been very slow and, as a consequence, the contribution of domestic credit to the economic expansion of the 2000s can be considered almost negligible.     

Dynamic relationship between Turkey and European countries during the global financial crisis

This study examines the relationship between time-varying risk perceptions of investors towards major European countries and Turkey. In that manner, we first obtain the dynamic conditional correlations between the credit default spreads (CDSs) of Turkey and 13 European countries from September 2004 to April 2013. Next, we endogenously detect the shifts in these dynamic correlation levels using a penalized contrast methodology. Accordingly, we find positive level shifts in all correlations following the US crisis. The upward trend in all CDS correlations holds during the eurozone debt crisis, but positive changes in correlations are not flagged as level shifts by the model, except in a few cases. The results suggest that Turkey is not immune to global financial conditions and there is integration between Turkey and the major European economies in terms of risk perception after the global financial crisis.     

金融危机背景下信用违约互换道德风险研究

2007年爆发的金融危机中,信用违约互换蕴含的道德风险使其成为危机发生和发展的助推器。本文通过构建信用违约互换交易的合约设计模型,研究该产品的作用以及控制其道德风险的最优合约设计。分析发现:交易双方资金成本差异决定了信用违约互换具有优化配置信用风险、提高银行收益和拓宽市场主体投资渠道等有利作用,但信用违约互换交易会降低银行监督信贷资产的努力水平,导致信用风险积聚和增加。通过引入不完全保护机制,我们给出了有效控制信用违约互换道德风险的最优合约。本文的研究结论为防范和控制信用衍生品隐含的道德风险提供了借鉴,有利于促进其发挥分散信用风险等积极作用。

Financial constraints on export market exit of domestic firms versus foreign multinational corporation subsidiaries in South Korea

Using a Korean manufacturing firm-level data set covering a range of years from 2006 to 2013, this study investigates how the financial condition of firms, such as liquidity, leverage, and cash flow ratio, affects exit from export markets. It also analyses whether the financial status of foreign multinational corporation (MNC) subsidiaries differs from that of domestic firms with respect to the hazard of export market exit, especially during a global financial crisis. The empirical results confirm that, for domestic firms, the hazard of export market exit is affected by the firms’ financial condition only during a financial crisis. In other words, the financial vulnerability of domestic firms increases during the crisis, resulting in the hazard of export market exit. However, financial situations for foreign MNC subsidiaries do not affect exits from export markets, indicating a ‘finance-factor comparative advantage’.
