混业经营与金融体系稳定性:基于银行危机的全球实证分析

银行混业经营不仅关系到自身效率的提高,更关系到银行体系乃至整个金融体系的稳定性。对全球范围内61个国家的跨国数据进行的实证分析表明,一个国家对银行混业经营的限制越少,该国的金融体系越趋于稳定,发生银行危机的概率也越小。不仅如此,在宏观经济越不稳定的国家,其一般性银行危机演变为系统性银行危机的概率也越大。     

金融危机冲击与企业现金持有的动态调整

运用动态面板模型及系统GMM估计方法,得出不同财务特征的企业在解释现金持有及动态调整速度与成本方面的差异,发现金融危机会显著增加公司调整持有现金的成本。进一步分析显示,正常状况下公司进行现金调整的资金来源主要依靠银行贷款与经营性现金流量,但在金融危机冲击时,中国上市公司对银行融资性资金来源的依赖更为明显,这与我国以银行为主体的间接融资方式相一致。     

Banking System Reform in China: The Challenges to Improving Its Efficiency in Serving the Real Economy

The Chinese banking system reform since the country's accession to the World Trade Organization has yielded remarkable success. The major listed commercial banks have improved their operational performance significantly. However, there are some signs of changes in their financial results recently. The expanding debt of non‐profitable enterprises and local governments raises a question on the achievements of the previous reform. Considering that the competition among banks will become severer with financial liberalization under slower economic growth, the banks and supervisory authorities must continue to make greater efforts towards further reform in order to improve the banks' corporate governance and the risk management system.     

HOW DOES FOREIGN BANK OWNERSHIP IN THE BANKING SECTOR AFFECT DOMESTIC BANK BEHAVIOUR? A DYNAMIC PANEL DATA ANALYSIS

The purpose of this paper is to investigate how foreign bank ownership in the banking sector affects domestic bank behaviour and whether this relationship depends on the economic and financial conditions of the host country. This paper contains 795 individual banks in 39 countries covering the period 1999–2006. Foreign ownership is calculated using bank level data as a proxy for the degree of foreign bank ownership in the banking sector. First, we find that foreign bank ownership is associated with a decrease in both the profitability and overhead expenses of the domestic bank after applying the system panel Generalized Method of Moments model. Second, a lower level of economic development of the host country enhances the positive effects of foreign bank ownership on the income, profit and cost of domestic banks. Third, financial development plays an important role in determining the effect of foreign bank ownership. Fourth, while the use of aggregate foreign ownership data may provide us with a big picture, it may not explain why individual banks in the same country perform differently, which this study will answer.     

Money and the ‘Level Playing Field’: The Epistemic Problem of European Financial Market Integration

ABSTRACT

Financial market integration processes in the European Union (EU) are characterised by an epistemic problem of economic theory. This problem encompasses what ‘the market’ is, how it is to be ‘integrated’, and the nature and role of ‘money’ as infrastructure of the fully integrated market. The EU’s legal framework has imported this epistemic problem along with the competitive conception of the market as described in economic theory – as a ‘level playing field’ for private exchange, under free, fair and ideally unrestrained competition. It manifests itself in European financial market integration processes, as exemplified in the article, via two otherwise disconnected areas of European Central Bank (ECB) activity: (a) the provision of central bank credit for the purpose of financial transaction settlement in the Eurozone; and (b) the conduct of ordinary monetary policy in the Eurozone. While the problem can be stabilised through legal, technical and other means, it remains latent, and may manifest itself again in unexpected ways, as happened in the wake of the 2008 financial crisis. Thus, contrary to ideologies that are widely understood as more or less coherent systems of doctrines, epistemic problems are characterised by specific tensions, contradictions and conceptual uncertainties.     

Heteroscedasticity of deviations in market bubble moments – how the goods and bads lead to the ugly

We conjecture that market bubbles may be the results of the interplay of Goods and Bads (toxic products) which develop through three interlocking moments – herding, swarming and stampeding, with deviations marked by heteroscedasticity. We use our stylized model of financial predation, the Consolidated Model of Financial Predation, and data we have accumulated through in-the-field eight-year research and the study of 30 years of U.S. market history in order to explore the foundations of market crises. We find that blind trust (or the positivity bias) and of the fear to miss out on an opportunity to enter/exit a market impacts the investors’ decisions to invest or retract. We show how markets are driven towards a make-or-break predatory dynamic that creates winners and losers due in part to weak regulations and identify a constant k that permeates market behaviours.     

Does financial cooperation agreement improve the cointegration among ASEAN+3 money markets?

This paper aims to empirically examine the degree of cointegration among ASEAN+3 money markets in order to determine and adopt remedial actions pursuant to vulnerabilities in the region’s money markets that indicate an inability to prevent possible financial crises. In order to validate vulnerabilities, this paper investigates the degree to which money markets are integrated. Inter-bank lending rates are divided based on agreement periods as well as on income levels of regional economies. The VAR-based Cointegration test and the VECM have been applied in the investigation process. The findings are: (1) weak integration during the pre-agreement period; (2) substantial progress toward the post-agreement period; (3) both high- and low-income markets integrate in a cooperative way; and (4) the agreement produces an impact that is incomplete in so far as integrating the region’s money markets. The finding of this study offers implications for the regional makers.     

Identifying the global transmission of the 2007–2009 financial crisis in a GVAR model

The paper analyses and compares the role that the tightening in liquidity conditions and the collapse in risk appetite played for the global transmission of the financial crisis. Dealing with identification and the large dimensionality of the empirical exercise with a Global VAR approach, the findings highlight the diversity of the transmission process. While liquidity shocks have had a more severe impact on advanced economies, it was mainly the decline in risk appetite that affected emerging market economies. The tightening of financial conditions was a key transmission channel for advanced economies, whereas for emerging markets it was mainly the real side of the economy that suffered. Moreover, there are some striking differences also within types of economies, with Europe being more adversely affected by the fall in risk appetite than other advanced economies.     

The linkages,persistence, asymmetry in the volatility,the price discovery and efficiency,and the effect of the US subprime mortgage financial crisis on the spot and the futures market’s returns: the case of India

This article examines the effects of persistence, asymmetry and the US subprime mortgage crisis on the volatility of the returns and also the price discovery, efficiency and the linkages and causality between the spot and futures volatility by using various classes of the ARCH and GARCH models, and through the Granger’s causality. We have used two indices: one for spot and the other for futures, for the daily data from 12 June 2000 to 30 September 2013 from Nifty stock indices. We have then tested for ARCH effects, and subsequently employed various models of the ARCH and GARCH conditional volatility. The GARCH(1,1) model is found to be significant, and it implies that the returns are not autocorrelated and have ‘short memory’. It supports the hypothesis of the efficiency of the markets. The negative ‘news’ has more significant effect on volatility, corroborating the ‘leverage impact’ in finance on market volatility. We have also tested the volatility spillover effects. The two methods we employed support the spillover effects and the causality is bidirectional. We also have used the dummy variable for the US subprime mortgage financial crisis and found that they are statistically significant. Indian stock market is thus integrated to the world stock markets.     

CAN INFORMATION AND COMMUNICATION TECHNOLOGY IMPROVE STOCK MARKET EFFICIENCY? A CROSS‐COUNTRY STUDY

The rapid advance of information and communication technology (ICT) has revolutionized the dissemination of stock market information. Based on the noise trading theory, this study discusses whether the changes brought by ICT have promoted the transparency of stock market information or instead flooded the stock market with misinformation. A cross‐country panel dataset of 71 countries from 2002 to 2014 was established. The empirical methodologies include panel unit root tests, panel variance ratio tests, and panel multiple regressions. The results of panel unit root tests and panel variance ratio tests show that stock markets in countries with high ICT diffusion are efficient while stock markets in countries with low or medium ICT diffusion are not all efficient. The results of panel regressions further show that the effect of ICT diffusion in reducing market noises was more significant than its effect in magnifying the noises.
