财政存款、银行竞争与僵尸企业形成

银行以优惠利率贷款为低质企业“输血”,是企业僵尸化的重要成因。然而,基于中国背景的文献,对银行“输血”动机的研究并不充分,本文从地方财政存款影响银行信贷分配的视角,分析僵尸企业形成的内在机理。首先,通过构建理论模型对银行竞争财政存款及影响企业融资和投资绩效进而僵尸化的逻辑进行刻画,而后依据省份财政存款、银行竞争与微观企业财务数据,对理论推论进行了验证。研究发现,财政存款占当地存款比重越大,企业僵尸化概率越高,并且银行竞争助长了企业僵尸化。此外,基于工具变量估计处理了核心变量的内生性问题,并进行了多种稳健性检验。机制检验表明,财政存款的信贷分配效应,促使企业过度投资,导致经营绩效恶化,进而提高了企业僵尸化概率,银行竞争则会加剧该效应。本文拓展了财政存款的经济效应与僵尸企业形成方面的文献,对于僵尸企业治理有一定参考意义。     

中国银行业市场结构演变的金融稳定效应研究

银行业市场结构模式到底是“集中-稳定”还是“集中-脆弱”观点尚未达成一致,但是通过采用熵值分解指数来刻画我国银行业市场结构可以针对该问题给出较为合理的答案。研究结果表明,我国银行业市场结构的集中程度与风险之间的关系是负相关的,我国较高的银行业市场集中度,某种程度上提高了我国银行业体系的稳定程度。     

Interbank contagion and resolution procedures: inspecting the mechanism

This paper develops a network model of a stylized banking system in which banks are connected to one another through interbank claims, which allows us to study the diffusion of default avalanches triggered by an exogenous shock under a number of different assumptions on the degree of interconnectedness, level of capitalization, liquidity buffers, the size of the interbank market and fire-sales. We expand upon the existing literature by comparing two alternative resolution mechanisms: (i) liquidations triggered by either illiquidity or insolvency-related distress implying asset sales and compensation of creditors; and (ii) a bail-in mechanism avoiding bank closure by forcing a recapitalization provided by bank creditors. Our model speaks to how contagion dynamics unravel via illiquidity-driven defaults in the first case and higher-order losses in the latter one. Within this framework, we show how the liquidity risk externality can be resolved, and we put forward a macro-criterion to assess the adequacy of the liquidity ratio introduced with Basel III.     

The Panzar–Rosse revenue test and market power in banking

The Panzar–Rosse H statistic is a commonly used measure of market power in banking. It is widely believed that $H>0$ is inconsistent with significant market power. This study rigorously disproves that perception. Instead, the possibility of $H>0$ under conditions of substantial market power turns out robust to the timing of banks’ actions, relative costs, choice of strategic variable, degree of product differentiation, strategy (static or dynamic), and degree of heterogeneity in banks’ conduct (collusive versus fringe), and hence may be common in practice.     

Is the Euro-zone on the Mend? Latin American examples to analyze the Euro question

Several European countries face challenges reminiscent of those faced by the emerging economies of Latin America. The economic booms in some peripheral Euro-zone countries financed by large capital inflows; the credit and asset price booms and then the busts including Sudden Stops in capital flows; the strong interaction between sovereign debt and domestic banking systems; the role of foreign banks and contagion; and all in the context of a fixed exchange rate, are familiar plotlines for Latin American audiences. For those Euro-zone countries that built up large Euro-denominated external liabilities, Latin America’s experience is particularly relevant and worrisome. Still, Europe may be in a better position to navigate a path out of the crisis given cooperative mechanisms that were absent in Latin America, particularly the availability of massive liquidity support. Nonetheless, while such support buys time, it does not guarantee success. This paper argues that reflecting on Latin America’s experience provides useful lessons for Europe to improve the chances for a successful resolution.     

中国影子银行发展趋势与展望

在多角度界定影子银行的基础上,总结中国影子银行的主要特征,即处于初期发展阶段、杠杆率相对较低、主体独立性低、金融创新活跃地带。从欧美国家影子银行发展实践来看,中国影子银行是金融体制过渡性的产物,代表了未来金融创新的方向,其发展趋势主要包括：业务发展：由银行表外业务向资产证券化业务转变;运作模式：由＂一对一＂对接向＂多对多＂对接转变;融资结构：由非标债权融资向标准化债权融资转变;体系构成：由商业银行为主向非银行金融机构为主转变;监管动向：由机构监管向机构监管与功能监管相结合转变。     

Do political factors influence banking crisis?

This paper investigates the impending political determinants of banking crisis in advanced economies. In particular, we consider the impact of domestic credit growth on the likelihood of banking crisis and analyse possible constraints on the part of the governments in curbing the unsustainable credit growth. The endogeneity corrected results reveal that the household credit growth has greater impact on the likelihood of banking crisis than the enterprise credit growth. The political channel shows that if governments are concerned about domestic approval rates, then there is a higher chance of credit boom, which in turn increases the prospect of banking crisis. Interestingly, the findings reveal that the presence of an independent and well-functioning central bank mitigates the crisis probability and reduces the opportunistic behaviour of governments.     

The synergistic effect of insurance and banking sector activities on economic growth in Africa

It is widely understood that the insurance and banking sectors of every economy perform some functions in driving economic growth. What is not yet well documented is whether their roles are complimentary or substitutive. With the aid of the dynamic panel generalized method of moments (GMM) estimation technique, this paper evaluates the synergistic effect of both sectors on economic growth in a panel of 10 African countries that are responsible for most of the activities in the continent’s financial sector. The insurance-banking-growth nexus was also examined through bootstrap panel causality tests. The results show that the life insurance market and the banking sector, as well as the non-life insurance market and the banking sector, are complimentary. We find that, overall, the relationship between the insurance and banking sectors in Africa is a complimentary one and that their synergistic impact on economic growth is positive. The feedback hypothesis was also confirmed in the relationship between the insurance sector and economic growth and between the banking sector and economic growth.     

Dynamical macroprudential stress testing using network theory

The increasing frequency and scope of financial crises have made global financial stability one of the major concerns of economic policy and decision makers. This has led to the understanding that financial and banking supervision has to be thought of as a systemic task, focusing on the interdependent relations among the institutions. Using network theory, we develop a dynamic model that uses a bipartite network of banks and their assets to analyze the system’s sensitivity to external shocks in individual asset classes and to evaluate the presence of features underlying the system that could lead to contagion. As a case study, we apply the model to stress test the Venezuelan banking system from 1998 to 2013. The introduced model was able to capture monthly changes in the structure of the system and the sensitivity of bank portfolios to different external shock scenarios and to identify systemic vulnerabilities and their time evolution. The model provides new tools for policy makers and supervision agencies to use for macroprudential dynamical stress testing.
