银行脆弱性与我国银行脆弱性治理

从银行的自身特征来看,银行机构天然具有脆弱性。当这种脆弱性累积到一定程度后,就有可能引发银行危机。银行危机的生成机理,可以概括为银行体系内脆弱性聚集、临界点冲击、银行危机爆发三个阶段。根据我国银行业发展现状,政府部门为了有效治理银行体系脆弱性,一方面要将传统的行政约束转变为法律约束,另一方面要将银行分支机构的经营主体地位法律化。在加强法律约束的同时,重建储蓄银行序列,进一步加强银行组织体系建设。     

Risk pricing of wholesale funds and the behavior of retail deposit rates

We explore the relationship between bank risk and retail deposits. Predicted risk premiums on wholesale funds explain retail rate heterogeneity through two channels. First, increased bank risk premiums encourage the bank to substitute from wholesale funds to small certificates of deposits (CD) by increasing small CD rates. Second, increased rival risk premiums in a local market require the bank to increase small CD rates even more. Our results are consistent with risk encouraging the use of small CDs as a marginal source of funds and promoting local market competition for small CDs. As risk premiums rise, banks also reduce rates on other retail deposits. Our approach has implications for regulatory and monetary policies and financial stability.     

Informational Contagion of Sudden Stops in a Global Games Framework

This paper highlights the cross-country spread of self-fulfilling financial crises through an informational channel. It sets up a two-country framework of investment with strategic complementarities and incomplete information about economic fundamentals. Each market may be subject to sudden stops, triggered by agents preemptively withdrawing their investments for fear others do so. After observing a massive capital outflow from one country, agents downgrade common fundamentals, and therefore have higher requirements regarding factors specific to the other country. This in turn may induce a crisis in the latter, which is not justified by idiosyncratic events or economic interdependence.     

The Effect of Bank Debt Downgrades on Stock Prices of Other Banks

We find that debt downgrades of money center banks elicit negative stock price responses in nondowngraded money center banks. Stock prices of larger regional banks also react to these downgrades. Although downgrades of regional banks evoke negative stock price responses for regional banks in the same geographic region, the importance of geographic region as a factor determining the extent of intra‐industry reactions has diminished since 1989. Our results indicate that the merger and expansion activities triggered by interstate banking have blurred differences between regional and money center banks as interstate banking activity has moved towards nationwide banking     

Regulatory Uncertainty and Financial Contagion: Evidence from the Hybrid Capital Securities Market

This paper examines the negative market impact that resulted from the insurance regulators’ potential reclassification of 140 hybrid capital securities in spring and summer 2006. It illustrates how financial contagion can spring from a regulatory policy change that lacks transparency. We investigate the impact of the uncertainty surrounding the regulators’ true classification criteria by measuring the effect of the reclassification announcements on hybrid new issue volume, cumulative average abnormal returns, bid‐ask spreads, and yield spreads. The financial contagion adversely affected the entire hybrid capital securities market for six months. The effect was most pronounced among those hybrids that were eventually reclassified as common equity equivalents. It was greater for Yankee Tier 1 hybrids, which had been more popular with insurance firm investors prior to the reclassifications, than among non‐Tier 1 hybrids.     

Beliefs, Bailouts and Spread of Bank Panics

This article highlights the spread of bank panics across countries, as the public reassesses governments' propensity to bailouts. Policymakers decide whether to save collapsing banking systems by weighing social costs of crises against the costs associated with raising taxes to finance rescue packages. Policymakers know those social costs of bank liquidation whereas the public does not. In this setup, financial crises may result from the public's self‐fulfilling prophecies about equilibrium outcomes, as lenders' expectations impinge on the taxation cost of bailouts. It follows that a banking crisis in a country leads creditors to reexamine policymakers' willingness to bailouts in other countries, which eventually makes their banks more vulnerable to self‐confirming depositors' runs.     

Financial Modernization in US Banking Markets: A Local or Global Event?

Abstract:   We test the hypothesis that the passage of the Financial Services Modernization Act (FSMA) of 1999 has spillover effects cross‐nationally, using a sample of US, non‐US transactional (Australian, Canadian, and UK), and relationship (German, Japanese, Dutch, and Swiss) banks. Our results suggest that financial modernization in the US has limited cross‐national effects. We find strong evidence that US banks were affected favorably. Although we detect some evidence of significant reactions by banks in certain countries, a closer examination reveals that the reaction is most likely attributable to events in the respective countries during the event period. We do find, however, that non‐US transactional banks have been more likely to elect financial holding company status compared to relationship banks, suggesting they are positioning themselves to exploit the expanded opportunity set created by the FSMA. Nonetheless, the majority of elections have been made by US banks. In general, the results suggest that the respective banking markets are efficient in filtering events that are largely country‐specific with only limited implications for other international banks.     

资产负债表的直接传染--一种银行与企业信用链上的信贷冲击乘数效应

文章立足于中国垄断竞争型的信贷市场,以直接金融对银行间接金融的替代性较弱为前提,深入分析了在经济或金融紧缩时期,银行贷款收缩或变动通过资产负债表的直接传染可能产生的一种信贷冲击乘数效应,并且指出,这种乘数效应可能与现有文献所研究的信用渠道中的银行借款渠道和金融加速器效应形成相互强化机制,进一步放大信贷变动对经济造成的冲击.     

The more others care,the more you share? – Social contagion as a stardom trigger of social media superstars –

Emerging superstars on social media platforms reshape the media landscape. This research analyses social contagion as a stardom trigger of social media superstars (SMS). We argue that in addition to serving as a quality indicator, the number of observed consumers of SMS performances also indicates the suitability of discussing the SMS performances with others. We experimentally manipulated the number of previous views of a YouTube video and find that a high number of previous views significantly increases the perceived quality and the video’s discussion suitability even when holding all objective video characteristics constant. We discuss implications for aspiring SMS and (online) marketers.     

国内外黄金市场风险传染的实证研究

以国际黄金市场上具有代表性的伦敦黄金现货价格和我国上海黄金交易所的黄金现货价格作为研究对象,利用多元GARCH模型对国内外黄金市场的风险传染机制进行了实证研究。结果表明：伦敦黄金市场对我国黄金市场存在单方向的均值溢出效应;从波动溢出效应来看,伦敦黄金市场对我国黄金市场的风险传染强于我国黄金市场对伦敦黄金市场的风险传染,存在着风险传染的非对称性。
