This paper investigates whether, and through which channel, the active use of credit derivatives changes bank behavior in the credit market, and how this channel was affected by the crisis of 2007–2009. Our principal finding is that banks with larger gross positions in credit derivatives charge significantly lower corporate loan spreads, while banks׳ net positions are not consistently related to loan pricing. We argue that this is consistent with banks passing on risk management benefits to corporate borrowers but not with alternative channels through which credit derivative use may affect loan pricing. We also find that the magnitude of the risk management effect remained unchanged during the crisis period of 2007–2009. In addition, banks with larger gross positions in credit derivatives cut their lending by less than other banks during the crisis and have consistently lower loan charge-offs. In sum, our study is suggestive of significant risk management benefits from financial innovations that persist under adverse conditions – that is, when they matter most. 相似文献

The current financial crisis has arisen as a result of entrepreneurial and business error rather than because of inappropriate incentives within the private sector. However, government failure has exacerbated the problem. The case for responding to government failure by greater international co-ordination of banking regulation is weak. The IMF is particularly ill-suited for this job. 相似文献

温家宝总理在2011年3月的政府工作报告中一再强调,2008年金融危机是百年罕见的国际金融危机。对于2008年金融危机产生的原因,各国学者似乎已达成一致共识。文章结合相应的经济理论基础与各国应对金融危机的成效,创新性地提出2008年金融危机产生的原因是科技创新遇阻,认为里程碑式的科技创新成果将是本轮金融危机成为过去的标志。 相似文献

We analyze the conditions of emergence of a twin banking and sovereign debt crisis within a monetary union in which: (i) the central bank is not allowed to provide direct financial support to stressed member states or to play the role of lender of last resort in sovereign bond markets, and (ii) the responsibility of fighting against large scale bank runs, ascribed to domestic governments, is ensured through the implementation of a financial safety net (banking regulation and government deposit guarantee). We show that this broad institutional architecture, typical of the Eurozone at the onset of the financial crisis, is not always able to prevent the occurrence of a twin banking and sovereign debt crisis triggered by pessimistic investors’ expectations. Without significant backstop by the central bank, the financial safety net may actually aggravate, instead of improve, the financial situation of banks and of the government. 相似文献

国际上金融危机发生后,其影响会传导到我国,影响我国的金融渠道各个指标,但对金融渠道整体的影响情况没有直观的指标反映,本论文合成的金融渠道传导综合指数可以反映金融危机的传导对我国金融渠道综合情况的影响,为危机发生后的调整工作提供基础.本文以最近一次世界金融危机——美国次贷危机为例,首先选取了危机传导指标集,其次运用SPSS相关分析,研究14个参考指标间的关系,确定我国金融渠道传导的合成指标,最后将其合成金融危机金融渠道传导综合指数,并根据合成结果绘制了走势图,实证结果表明此综合指数能够反映金融危机传导中我国金融市场的综合情况.本文的研究对减小金融危机的传播范围有着重要理论价值,对开放中的中国具有重要的现实意义. 相似文献

This paper examines the potential for contagion within the Czech banking system via the channel of interbank exposures of domestic banks, enriched by a liquidity channel and an asset price channel, over the period March 2007 to June 2012. A computational model is used to assess the resilience of the Czech banking system to interbank contagion, taking into account the size and structure of interbank exposures as well as balance sheet and regulatory characteristics of individual banks in the network. The simulation results suggest that the potential for contagion due to credit losses on interbank exposures was rather limited. Even after the introduction of a liquidity condition into the simulations, the average contagion was below 3.8% of the remaining banking sector assets, with the exception of the period from December 2007 to September 2008. Activation of the asset price channel further increases the losses due to interbank contagion, showing that the liquidity of government bonds would be essential for the stability of Czech banks in stress situations. Finally, the simulation results for both idiosyncratic and multiple bank failure shocks suggest that the potential for contagion in the Czech banking system has decreased since the onset of the global financial crisis. 相似文献

How did DSGE model forecasts perform before, during and after the financial crisis, and what type of off-model information can improve the forecast accuracy? We tackle these questions by assessing the real-time forecast performance of a large DSGE model relative to statistical and judgmental benchmarks over the period from 2000 to 2013. The forecasting performances of all methods deteriorate substantially following the financial crisis. That is particularly evident for the DSGE model’s GDP forecasts, but augmenting the model with a measure of survey expectations made its GDP forecasts more accurate, which supports the idea that timely off-model information is particularly useful in times of financial distress. 相似文献

Recent empirical evidence based on surveys and experimental activities within the fields of behavioral finance and financial education has offered economists new empirically based insights into how individuals use information in making financial decisions. Specifically, the importance of information in financial decisions may be reduced or eliminated by psychological aspects of the individual, such as a state of overconfidence that is individual or shared with a group, or by the individual's limited ability to process complex and abundant information. This paper aims to complement this emerging body of literature by studying how individuals perceive and process information when making financial decisions. We review these contributions and suggest a number of broad guidelines that can provide a framework for future discussion of this topic within financial decision theory. 相似文献

This paper considers the impact of the 2008 short selling bans on the cross-market dynamics of stock indices across a wide range of countries. We measure the transmission of shocks between markets using a modified version of the spillover index of Diebold and Yilmaz (2009). The results show that the transmission of shocks between countries which did impose short sale bans was reduced and transmissions from countries with bans to countries without bans were also generally lower. In contrast, short sale bans did not provide protection from shocks emanating from countries which did not impose bans, as shocks from non-banning markets tended to have an increased impact on other markets during periods where bans were in place. Overall, the evidence supports the redirection of volatility in the system affecting the relationships between the groups of markets with bans and those without. 相似文献

A Primer on Financial Contagion 总被引：8，自引：0，他引：8
Abstract. This paper presents a theoretical framework to highlight possible channels for the international transmission of financial shocks. We first review the different definitions and measures of contagion adopted by the literature. We then use a simple multi-country asset pricing model to classify the main elements of the current debate on contagion and provide a stylized account of how a crisis in one country can spread to the world economy. In particular, the model shows how crises can be transmitted across countries, without assuming ad hoc portfolio management rules or market imperfections. Finally, tracking our classification, we survey the results of the empirical literature on contagion. 相似文献
