Corporate governance in banking: The role of the board of directors

We use a sample of large international commercial banks to test hypotheses on the dual role of boards of directors. We use a suitable econometric model (two step system estimator) to solve the well-known endogeneity problem in corporate governance literature, and demonstrate the empirical and theoretical superiority of system estimator over OLS and within estimators. We find an inverted U-shaped relation between bank performance and board size, and between the proportion of non-executive directors and performance. Our results show that bank board composition and size are related to directors’ ability to monitor and advise management, and that larger and not excessively independent boards might prove more efficient in monitoring and advising functions, and create more value. All of these relations hold after we control for the measure of performance, the weight of the banking industry in each country, bank ownership, and regulatory and institutional differences.     

中国商业银行宏观绩效与微观绩效相关性研究

本文以商业银行的不良贷款率和对经济增长的贡献度分别作为其微观绩效和宏观绩效的代理变量,建立了宏观绩效与微观绩效相关性的误差修正模型,通过对我国13家商业银行1995-2005年的数据进行分析．揭示两者之间的关系。本文研究结果表明：商业银行对经济增长的贡献度越大,不良贷款率越高,两重绩效之间存在替代关系,均衡误差项存在反向修复机制。最后,本文分析了误差修正模型的政策含义,提出缓解两重绩效冲突的政策措施。     

上市公司董事会特征对公司绩效影响的分析

文章以沪深两市百强名单中的董事会作为研究对象,借助SPSS统计软件,分析上市公司董事会特征对公司绩效的影响。结果表明：四项董事会特征与公司绩效均没有明显的相关关系。这表明目前我国上市公司还未能通过优化董事会特征来提高董事会效率进而提高公司绩效,上市公司治理存在很大的改进空间。文章提出了优化董事会成员结构、优化薪酬制度、建立健全董事任用和绩效评估机制等对策建议。     

董事会行为与公司业绩关系研究——一个理论框架及我国上市公司的实证检验

本文研究了董事会行为与公司业绩之间的关系。我们首先从董事会成员的能力、努力程度和董事会组织认同与和谐等三个方面提出了董事会行为与公司业绩相关性的逻辑框架。然后,利用我国沪市上市公司的数据对董事会行为与公司业绩之间的相关性进行了实证检验。研究结果表明,董事会成员的能力、努力程度与公司业绩正相关,董事会成员之间的和谐程度与公司业绩相关。这表明董事会行为确实影响着公司业绩,而且这种影响比起董事会结构与特征更为直接。     

我国商业银行绩效考核机制现状及改革策略

Board diversity,firm risk,and corporate policies

We examine the effects of diversity in the board of directors on corporate policies and risk. Using a multidimensional measure, we find that greater board diversity leads to lower volatility and better performance. The lower risk levels are largely due to diverse boards adopting more persistent and less risky financial policies. However, consistent with diversity fostering more efficient (real) risk-taking, firms with greater board diversity also invest persistently more in research and development (R&D) and have more efficient innovation processes. Instrumental variable tests that exploit exogenous variation in firm access to the supply of diverse nonlocal directors indicate that these relations are causal.     

商业银行董事会治理：特征与绩效——基于美国银行业的实证研究

本文以1996—2005年间美国43家商业银行为样本,实证分析了商业银行董事会治理的特征及其对绩效的影响。研究表明:平均而言,商业银行董事会的规模略大于非金融性企业的这一指标,且外部董事的比例较高;董事会规模与银行绩效之间存在非线性的倒U型曲线关系,但外部董事的比例对银行绩效的影响不显著;董事长与总经理两职合一、董事会次级委员会的数量、外部董事拥有的董事席位数均与银行绩效显著负相关;董事会会议频率对当年度银行绩效的影响不显著,但与前一会计年度的绩效之间存在显著的负相关关系;董事持股比例与银行绩效之间存在非线性的关系,而总经理任职年限对银行绩效的影响不显著。     

Board size and firm performance: the moderating effects of the market for corporate control

We examine whether takeover threats affect the importance of board size using the passage of state antitakeover laws enacted in mid-to-late 1980s as our empirical setting. While the Complement Hypothesis predicts that board size matters more before the passage of the laws, the Substitute Hypothesis predicts the opposite. For a sample of 350 Forbes 500 firms over the period 1984–1991, we find a significant association between smaller boards and better firm performance before passage of antitakeover laws, but a much weaker relation (reduced by more than one-third) after the takeover restrictions were in place. Consistent with the Complement Hypothesis, this finding suggests that decreasing board size is more valuable when the market for corporate control is more active.

Comparative Performance of Chinese Commercial Banks: Analysis,Findings and Policy Implications

This paper investigates the financial performance of Chinesebanks by using financial ratio analysis. The analysis shows that the lowprofitability of state-owned commercial banks results from their higherratio for non-interest expenses and lower interest margin thanjoint-equity banks. The much lower profit margin in state-owned banksdraws down their levels of ROE and ROA, even with the offsetting effectsof more efficient utilization of their assets and higher financialleverage. Although data limitations prevent us from studying the riskprofiles of the banks in detail, it is clear that these Chinese banksgenerated lower returns with higher financial risks than their Westerncounterparts. The paper concludes with a discussion of major issuesaffecting Chinese bank performance. Significant difficulties encounteredin assessing bank performance are also identified anddiscussed.     

董事网络、独立董事治理与高管激励

独立董事的治理行为受到所处社会网络的影响。基于"董事在董事会同时任职的直接或间接联结关系"而形成的董事网络,本文利用社会网络分析方法检验了独立董事的网络特征对其发挥在促进高管激励有效性影响中的作用机理。结果发现:公司独立董事网络中心度越高,高管薪酬-业绩敏感性越强;与非国有上市公司相比,国有上市公司中独立董事网络中心度与高管薪酬-业绩敏感性的正相关关系更弱;进一步研究发现,用独立董事网络中心度解释的高管薪酬部分对未来业绩有促进作用。结论丰富了"网络和治理"研究的证据。
