我国商业银行效率分析——基于超效率DEA和Malmquist指数

效率是银行经营管理的核心,是银行竞争优势的集中体现,尤其在后危机时代,提高银行业的效率也是防范金融风险,实现可持续发展的关键。本文基于超效率DEA方法,运用EMS软件对2004—2009年14家商业银行的效率进行分析,对其均值进行排名;并通过Malmquist指数对银行效率进行分解研究,重点分析金融危机前后的商业银行全要素生产率的变化趋势。结果表明,效率水平总体呈现上升趋势,这与社会经济的发展是相一致的。而四大国有银行的效率不及股份制商业银行,可见,四大国有银行并没有因为资产规模大,而带来更高的收益和绩效;2004—2009年商业银行全要素生产率整体上不断提高,主要得益于技术进步和规模效益,但2009年全要素生产率有所下降,受美国金融危机全面升级所导致的国际国内经济发展衰退的影响,经营风险加大,息差收窄,对银行盈利和效率产生不利影响。     

The joint effects of financial development and the business environment on firm growth: Evidence from Vietnam

This work examines the complementary effects of local financial development and the business environment on the growth of Vietnamese firms. For the period from 2009 to 2013, we combine firm-level data covering more than 40,000 firms from the Vietnam Enterprise Survey with province-level data from the Vietnam Provincial Competitiveness Indicators. Our estimation strategy builds upon a novel copula-based estimator that accounts for potential endogeneity biases without requiring external instruments. Our results show that financial development and a favourable business environment generally promote firm growth, but some components of the business environment, such as low entry costs, access to land and business service support, foster firm growth more strongly than financial development. Most importantly, financial development and the business environment interact positively in their effects on firm growth. The impact of local financial development on firm growth is higher in provinces with a competitive business environment. Conversely, improvements in provincial competitiveness have a greater impact on firm growth in provinces with a more developed financial sector. The results clearly show that policies to promote local financial development need to be coordinated with measures to improve the broader business environment.     

跨境资本流动与宏观周期研究述评

实际经济周期理论(RBC)无法解释国内偏好(Home Bias)和资产异质性(Idiosyncratic Asset)问题,因而无法全面阐释金融危机时期国际资本流动。通过大量文献将投资组合理论引入开放动态随机一般均衡(ODSGE)模型较好地解决了以上问题。与此同时,对国际资本流动的研究从一阶矩扩展到二阶矩,即由单独关注收益因素到关注收益因素并关注风险因素,构建了研究国际资本流动与经济周期波动一般性分析框架。这一新进展对于研究中国实施资本管制和构建国际资本流动管理体系具有较强的理论和现实意义。文章对以上研究成果进行了梳理,重点梳理了跨境资本流动与金融危机、周期波动的相关研究并对之进行述评。     

On the role of domestic and international financial cyclical factors in driving economic growth

ABSTRACT

We investigate the effects of (domestic and international) financial cyclical factors on the US business cycle over the period 1890–2013 using an augmented stochastic version of the neoclassical growth model. In our setting, financial factors enter as determinants of the total factor productivity cyclical pattern. By means of static and dynamic estimations we find that (i) the inclusion of financial cyclical factors improves the model’s performance; (ii) the sensitivity of economic growth to financial factors is time-varying; (iii) domestic financial factors have a key role in explaining short-run output fluctuations only in the first half of the 20th century; (iv) US business cycle fluctuations have been mainly driven by global financial factors (i.e., financial integration) over the last three decades.

Euro Area business cycles in turbulent times: convergence or decoupling?

We study the business cycle properties of the four largest European economies in the wake of the recent recession episodes. The analysis is based on the factors estimated from a multi-country and multi-sector data-rich environment. We measure alikeness of business cycles by studying the synchronization of up and down phases, the convergence properties of country fluctuations towards the Euro Area (EA) cycles and the contribution of the EA factor to national GDP volatilities. While the economic fluctuations of the four EA member states were similar before the global financial turmoil, we gather compelling evidence of an asymmetric behaviour of Spanish fluctuations relative to the EA one.     

Japan's productivity stagnation: Using dynamic Hsieh–Klenow decomposition

This study provides a new perspective on Japan's stagnant aggregate productivity by extending the Hsieh and Klenow (2009) framework to account for productivity growth, entry and exit, and product variety change. We measure the technical efficiency (TE) and allocative efficiency (AE) by the aggregate production possibility frontier and the distance from the frontier, respectively. We apply our approach to establishment- and firm-level data sets from Japan and find that the AE among survivors declined during the banking crisis period, while the TE declined during the global financial crisis period.     

The changing international transmission of U.S. monetary policy shocks: Is there evidence of contagion effect on OECD countries

We study the changing international transmission of U.S. monetary policy shocks to 14 OECD countries over the period 1981Q1–2010Q4. The U.S. monetary policy shock is defined as unexpected change in Effective Federal Funds Rate (FFR). We use a time varying parameter factor augmented VAR approach (TVP-FAVAR) to study the EFFR shocks together with a large data set of 265, major financial, macroeconomic and trade variables for U.S., Canada, France, Germany, Italy, UK, Japan, Australia, Spain, Norway, Sweden, Switzerland, Finland and New Zealand. Our main findings are as follows. First, negative U.S. monetary policy shocks have considerable negative impact on GDP growth in the U.S., Canada, Japan and Sweden while most of the other member countries benefits. Second, the transmission to GDP growth has increased in OECD countries since the early 1980s. We also detect a more depressed GDP over medium term in the U.S., Canada, Japan, Australia, Norway and Sweden over the recent global financial crisis. Third, the size of U.S. monetary policy shocks during financial turmoil periods were unusual than normal periods and varies overtime. The financial crisis (2008–2009) is evidenced by decline in residential investment in the U.S. and propagation of this shock to Canada, Germany, Japan, Switzerland and New Zealand over the recent period. U.S. monetary policy shocks reduce share prices in most of the OECD countries; this impact is more pronounced over the turmoil period. Asset prices, interest rates and trade channel seem to play major role in propagation of monetary policy shocks.     

Taking action to close the nursing-finance gap: learning from success

Nurse leaders control the largest part of a hospital labor budget, in some cases the largest part of the overall budget. The effectiveness of overseeing this responsibility can mean the difference between an organization's financial stability and financial turmoil. The nursing department at Northwestern Memorial Hospital took ownership of its financial performance. Over the past 2 years, their financial performance saved $4.9 million in productivity while reducing nurses turnover costs by $7.6 million. Valuable lessons from their experience are offered for improving health care's financial and operational outlook.     

EFFICIENCY AND HYBRIDIZATION IN COOPERATIVE BANKING: THE FRENCH CASE*

ABSTRACT: This paper analyzes how French cooperative banking groups adapted their organization, status and model to develop and grow, until the current financial crisis. It explores how they benefitted from evolutions in cooperative law that lowered financing constraints and increased the scope of their activities, becoming large banking groups, and identifies how these groups tried to develop a model of governance, characterized by internal control, which was partly dedicated to the members, but biased more and more towards the top of the organizational pyramid and to stockholders (the new stakeholders coming from the existence of listed vehicles). While the developing business model for cooperative banks appeared to confer a comparative advantage and was synonymous with efficiency before the financial crisis, it seems that the hybridization of the cooperative model has also been a source of conflict of interest, weakness in strategy and an incentive to increase risk. The third part of the article examines how French cooperative banking groups have been hurt by the recent crisis and whether different organizational and strategic features or choices may explain different levels of resilience to financial turmoil.     

Risk sharing and export performance with firm heterogeneity

We investigate how market uncertainty affects the export performance of a firm through financial frictions. We first extend Melitz's (2003) heterogeneous firm trade model by incorporating demand shocks, linking the demand uncertainties to the financing costs of firms. In this extension, the default probability is endogenously determined by a firm's productivity and demand uncertainty. Hence, firms with higher productivity or lower market uncertainty are offered lower interest rates and thus show better export performance. As an application, we also show that a risk-sharing mechanism, that pools default risk for a certain group of firms, lowers the default risk. This mechanism allows banks to charge lower interest rates to the member firms and therefore ultimately improves their export performance in both extensive and intensive margins. We find a real-world example of such a mechanism from business groups in Korea. Using Korean firm-level data, we show that the more diversified the business group, the greater the likelihood that its member firms export and the bigger their export revenues. We also show that our results are robust to alternative explanations for Korean business groups’ export competitiveness.     

金融发展与全要素生产率增长* ——基于中国省际面板数据的实证分析

本文以2000-2012年中国省际平衡面板数据为样本,从金融规模发展和金融效率发展两个维度衡量金融发展水平,实证检验金融发展与全要素生产率增长的联系以及中间渠道。研究结果发现,2000-2012年中国全要素生产率出现正增长且主要是由技术进步推动的;无论是从金融规模发展角度还是从金融效率发展角度去分析,都证实了金融发展显著地促进了全要素生产率的增长,金融效率发展的全要素生产率增长效应显著地高于金融发展规模的全要素生产率增长效应,且金融发展促进全要素生产率增长的中间渠道是技术进步效应而非技术效率增长效应;通过引入衡量金融发展缺陷程度指标（民间金融发展规模）,证实了中国金融发展体系效率低下。民间金融发展具有TFP增长效应,且民间金融发展TFP增长效应要显著地大于正规金融发展的TFP增长效应。     

The Short‐term Determinants of Capital Flows for a Small Open Economy: The Case of Greece

This paper presents the factors driving capital flows inwards and outwards of a small open economy such as Greece during the period 1983–2009. Apart from the determinants of capital flows the possibility of speculative attacks is also considered. Applying the ordinary least squares (OLS) method it is found that variables linked to external factors such as the differential of domestic and foreign interest rates and financial crises, such as the Asian and Russian financial turmoil of 1997 and 1998 respectively, are the main factors influencing capital inflows and outflows in Greece during the period 1983–2009. Additionally the results of probit analysis support that the same factors are significant in determining the probability of speculative attacks to the Greek economy.     

The countercyclical role of Italian local banks during the financial crisis

The article analyses the role of local banks in Italy during the 2008–2009 crisis from the perspective of the relationship lending model. During the crisis, the risk of cascading failures of financial organizations has dramatically increased, thus causing a return of attention to local banking as a possible source of countercyclical behaviours in the financial markets thanks to their ability to establish fiduciary long-term relationships with small businesses.

The purpose of this article is to test this hypothesis and to disentangle the response of local banks during the financial turmoil according to their governance structure and location. Our results show that non-independent local banks and, to a limited extent, cooperative banks located in the rural area actually played a significant countercyclical role across the crisis. Policy implications suggest that prudential supervision should rethink the indicators of systemic risk in order to differentiate banks according to their capability of mitigating it.     

Modeling,analysis and mitigation of contagion in financial systems

Recent financial turmoil (e.g., the 2008–2009 global financial crisis) has resulted in financial contagion-induced instability becoming one of the major concerns in the fields of economics and finance. In this paper, we extend the network analysis of financial contagion from three perspectives. First, given that cross-holding of claims and obligations among financial institutions can be viewed as input-output linkages, we model the financial system and the contagion mechanism by introducing the classic Leontief input–output framework. Second, based on this modeling process, we propose a simple contagion algorithm to study how financial system heterogeneity influences its stability. Third, to mitigate financial contagion, we propose several concrete intervention policies based on two widely used prudential approaches—forced mergers and capital injections. The performance of these intervention policies is then evaluated by comprehensive numerical experiments. Our study has significant implications for financial regulation and supervision.     

Typology for flight-to-quality episodes and downside risk measurement

We propose a total return-based framework to measure downside risk associated with phenomenon of capital outflows from riskier to safer financial markets. The proposed method consists of three elements: (i) the general definition of the flight-to-quality (FtQ) phenomenon, (ii) the typological classification of the flight-to-quality occurrences for associating them with the phases of the business cycle and (iii) the automated technique to diagnose the time frames and to measure the impact of flight-to-quality on financial instruments. The proposed framework is applied to analyse the global-scale capital inflows/outflows from emerging markets public debt to the US Treasuries and vice versa. The results show that different phases of business cycles and GDP growth rates, including turning points, could be associated with flights-to-quality of different types and causality origins. Addressing downside risk crystallizations in flight-to-quality occurrences, new perspectives of integrated interest rate risk and credit risk management are discussed. For strengthening financial stability, we suggest the use of flight-to-quality windows as scenarios for stress testing, both for banks and financial institutions.     

CAN INVESTMENT IN INTANGIBLES EXPLAIN THE SWEDISH PRODUCTIVITY BOOM IN THE 1990s?

In the early 1990s the Swedish economy experienced a severe economic and financial crisis which resulted in a substantial GDP decrease. Even though the crisis was not a complete surprise for many economists, almost no one expected that the Swedish economy would be prospering with booming productivity growth only a few years later. Economists have presented three explanations for the fast recovery and productivity growth in 1995–2006: market reforms, crisis recovery, and the impact of ICT. This paper offers an alternative view, emphasizing instead firms' substantial investment in intangible assets such as R&D, design, and advertising. Based on the growth accounting framework, intangible capital accounted for more than 30 percent of the labor productivity growth in the Swedish business sector from 1995 to 2006. Thus, Swedish TFP growth, one of the highest among OECD countries, is reduced substantially when investment in intangibles is included in the growth accounting analysis.     

中国金融发展与经济增长的关系分析

古典经济学家大多认为金融发展能促进经济增长,以往国内外文献的研究中也不乏此类观点,但是随着近些年我国信贷市场、股票市场以及债券市场的不断扩张,金融市场也在快速繁荣的发展,其在整个经济体系中的影响也越来越重要,我们有必要在新的发展阶段重新验证其在经济增长中的作用。文章特选取1992—2009年间的数据进行实证研究,结果显示:经济增长是金融发展的格兰杰成因,但随着滞后期的延长,这种作用越发不明显,同时金融发展对经济增长的作用也是显著的。     

Development of internal resources and capabilities as sources of differentiation of SME under increased global competition: A field study in Mexico

This paper draws on the resource-based view of the firm and contributes to our understanding of how the development of internal resources and capabilities in SMEs can provide sources of competitive advantages in the international arena and improve their business performance.This research found statistical evidence to suggest that business performance measured by growth rate, efficiency, productivity and shareholder's financial returns, is positively related with the development of internal capabilities such as soft technology (methods and processes that support the firm) and hard technology (externally acquired equipment, in-house development of machinery and innovation in raw materials) and a strategy of continuous improvement, innovation and change.A number of relevant contributions are proposed in this piece of research that expands our understanding of how SMEs can compete in the international context: (1) firms whose explicit business strategy emphasizes innovation and knowledge creation have been able to successfully participate in global contexts; (2) even though financial resources are important for a firm to leverage performance it was found that development of internal capabilities has been more important than limited financial resources in order to develop competitive advantages to compete with larger and multinational competitors; (3) results of this research support the proposition that from an associational economy perspective the development of a geographical region or country should be an interaction among a number of constituents namely government policies, the firms themselves and universities and research centers among others.     

Grant Assistance and Small Firm Development in Northern Ireland and the Republic of Ireland

Small business support is an important element of industrial development policy in both Northern Ireland and the Republic of Ireland. This paper examines the effect of grant support on small business performance from 1991–94. Around 50% of small businesses in Northern Ireland and 30% of small businesses in the Republic of Ireland received financial support over this period. In Northern Ireland, three clusters of assisted companies were identified who received support for marketing, training and capital investments. In the Republic of Ireland, two assisted clusters of firms were identified who received marketing and training grants. In each case, firms in the assisted clusters grew faster, tended to be more profitable, were more active in terms of sales and market development and adopted more ambitious strategic directions than those in the non‐assisted clusters. Selection models are used to explore whether these differences are due to differences in the characteristics of the assisted and non‐assisted groups or can be directly attributed to the effect of government financial support. In the Republic of Ireland there is no evidence of any effective targeting of assistance at better performing firms. In Northern Ireland, there is some evidence that assistance was targeted at firms with higher productivity growth. Grant aid had no effect on either the turnover growth or profitability of small businesses in either area. It did, however, boost employment growth. This is good‐news for job creation but has potentially worrying implications for firms' longer‐term competitive position through its negative effect on productivity.     

The evolution of firm-level distributions for Ukrainian manufacturing firms

We document rich variation across observed firms’ characteristics, and the accompanying macroeconomic volatility, often related to political turmoil for Ukrainian manufacturing firms. We use a unique annual firm-level data for the period from 2001 to 2009 compiled from the Derzhkomstat. To understand the evolution of distributions we utilize functional principal component analysis while accounting for the effects associated with firms’ region, industry, trade status, and firm turnover. The overall improvements in firm productivity in Ukraine’s manufacturing in 2001–2009 vary substantially by industry, trade status and with firm turnover, while regional effects are less important.
