农村金融机构经营效率测算及影响因素的空间计量分析——兼论农村金融机构改革

农村金融改革的目标之一在于提升农村金融机构的经营效率,但相关研究较少考虑不良贷款约束,对农村金融机构经营效率及其影响因素的空间计量也很少涉及。基于此,本文以较具代表性的沿海地区G省为例,运用非径向EBM-Undesirable模型从多个视角测算分析了农村金融机构的经营效率,并基于空间相关性检验和空间计量模型,对经营效率进行了空间效应分析与影响因素估计。结果显示:农村金融机构经营效率总体水平较高,但起伏较大;农商行效率高于农信社,但2015年后差距有所缩小;经营效率具有空间相关性,经济水平、产业结构、行业竞争、资产规模和盈利能力是驱动因素,隐形风险是阻碍因素。鉴此,本文提出了加快推进农商行治理能力建设和产品服务创新、将经营效率作为农信社改制的重要参考指标、监管部门和省联社给予针对性经营指导、深化邻近协同经营等政策建议。

Diversity and relative arbitrage in equity markets

An equity market is called diverse if no single stock is ever allowed to dominate the entire market in terms of relative capitalization. In the context of the standard Itô-process model initiated by Samuelson (1965) we formulate this property (and the allied, successively weaker notions of weak diversity and asymptotic weak diversity) in precise terms. We show that diversity is possible to achieve, but delicate. Several examples are provided which illustrate these notions and show that weakly-diverse markets contain relative arbitrage opportunities: it is possible to outperform or underperform such markets over any given time-horizon. The existence of this type of relative arbitrage does not interfere with the development of contingent claim valuation, and has consequences for the pricing of long-term warrants and for put-call parity. Several open questions are suggested for further study.Received: January 2004, Mathematics Subject Classification (2000): 60H10, 91B28; 60J55JEL Classification: G10We are grateful for the helpful remarks offered by seminar audiences at Columbia, Yale, Princeton, the Sloan School of MIT, Boston University, the Mathematical Institute in Oberwolfach, and the Universities of Athens, Connecticut/Storrs and Texas/Austin.

金融资本国际化绩效与条件分析

金融资本国际化一方面促进利率水平提高,从而促进储蓄增加;另一方面影响投资规模和投资效率,进而影响经济绩效。一国实施金融资本国际化的条件可以分为国内条件,即初始条件和对外条件,即可实施条件两个方面。     

财务动态治理论纲

传统财务治理理论侧重于财务治理结构和权利分布状态等静态范畴的研究,而忽略了财务动态治理的专门研究.财务治理可分解为基于企业公平的财务静态治理和基于企业效率的财务动态治理,它在本质上是一个二元价值体系,在实践上表现为企业公平和效率的并行与平衡.财务动态治理是对传统财务治理的继承和超越,它是剩余公司治理的集中领域和公司动态治理的核心,其理论基础溯源于企业产权契约理论、公司治理理论、公允价值会计计量理论和财务治理理论.以不完全合同中的完备部分和不完备部分为标准,财权可划分为通用财权和剩余财权.剩余财权配置是财务动态治理的核心,财务动态治理的基本内容包括动态治理结构、治理机制和治理行为规范.     

The role of ICT in reducing information asymmetry for financial access

This study assesses the role of ICT in complementing private credit bureaus (PCB) and public credit registries (PCR) in reducing information asymmetry for financial access. The empirical evidence is based on Generalised Method of Moments with 53 African countries for the period 2004–2011. The following findings are established. First on financial access: (i) the marginal effects from interactions between ICT and PCR (PCB) are consistently positive (negative); (ii) net effects from interactions are negative with the higher magnitude from PCR and (iii) only thresholds corresponding to interactions between PCR and internet penetration are within range. Second, findings on financial allocation efficiency reveal positive marginal and net effects exclusively for mobile phones and PCR. Third, allocation efficiency may be constrained by increasing financial deposits. Overall, the complementarity between information offices and ICT in boosting financial access is still very limited. Policy implications are discussed with emphasis on improving the engaged complementarity and fighting surplus liquidity.     

The role of managerial risk‐taking in the ‘rise and fall’ of the CDS market

Since the innovation of credit default swaps (CDSs) in 1997, the market for CDSs grew dramatically to $62 trillion in 2007 (ISDA 2010). However, this market declined significantly with the onset of the GFC, prompting the question, ‘What lies behind the phenomenal growth and the eventual collapse of the CDS market?’ Using CDS spread data from 319 bank and non‐bank financial institutions across 33 countries over the period 2001–2010, I provide evidence of the determinants that affect risk‐taking by financial institutions, proxied by CDS spreads, and argue within an agency theoretical framework that managerial risk‐taking contributed to the ‘rise and fall’ of the CDS market.     

次贷危机以来中央银行的作为——对中美两国央行资产负债表的考察和分析

随着次贷危机及之后蔓延全球的金融危机不断发展,对危机的研究也从不同角度展开。由于中央银行是负责一国货币政策的政府部门,也是危机中能够做出迅速有力反应的机构,因此对中央银行的研究非常重要。本文以中、美两国的中央银行作为观察对象,以它们的资产负债表作为切入点,研究中央银行在危机以来的行为。本文首先对2007年以来两国中央银行资产负债表的基本情况进行观察;然后对两个央行的资产负债表中所表现出的一些特征进行分析;进而对形成这些特征的原因及相关问题进行深入的探讨;最后对全文进行总结。     

建立和完善农村地方中小金融机构:一个适应中国农村经济发展的金融制度变迁

企业规模较小甚至以农户为单位的农村经济发展,对农村中小金融机构的建立和完善提出了强烈的需求,而以政府主导的农村金融改革却成效甚微。本文从农村经济发展引发对农村中小金融机构的诱制性制度需求与政府代表的强制性制度供给两方面的分析得出:农村地方中小金融机构制度建设,是农村经济发展的客观要求,同时也符合国家的效用函数。     

Social networks in the global banking sector

We show that banks with shared social connections partner more often in the global syndicated loan market and that central banks in the network play dominant roles in various interbank transactions, indicating that social connections facilitate business connections. However, more centralized banks in the network also contribute significantly to the global systemic risk. Moreover, we find the soft information generated by social networks is particularly valuable when potential partners operate under different accounting and regulatory standards. Finally, we show that the recent banking crisis significantly limited the positive soft information effects of social networks in the global banking system.
