信息约束下的金融监管与银行声誉

如何在信息不对称的约束条件下降低金融风险、提高监管绩效,是金融监管中的一项重要课题.本文分析了信息结构对于监管的重要性,认为声誉机制的建立可以降低银行与监管部门之间信息不对称的程度和风险发生的概率,并运用KMFW模型,分析了不对称信息下银行声誉机制减少违规动机的过程,指出应该注重激励相容的制度安排,将外部监管与自律有机结合起来,促使银行自发选择接受监管且减少进行高风险投资的动机,这是信息不对称条件下提高监管效率的重要策略.结合我国实情,本文提出可通过银行风险评级、建立可置信的惩罚机制、完善银行内部治理机构、改进监管人员激励约束机制、构建和完善金融监管信息系统等措施,建立健全银行声誉机制,以进一步改善监管绩效.     

Credit claiming

We consider a leader and a subordinate he appoints who work in a team. The public observes the organization’s performance, but not the separate contribution of the leader or of the subordinate. The leader may therefore claim credit for the good work of his subordinate. We find conditions which induce the leader to claim credit (both truthfully and untruthfully), and the conditions which lead the leader to appoint a subordinate of low ability.JEL Classification: M5Björn Segendorff gratefully acknowledge financial support from The Swedish Council for Research in Humanities and Social Sciences (HSFR, F0357/97).

农村社区公共物品的农户自愿供给——基于声誉理论的分析

农户的声誉不仅能给农户带来直接效用,它还具备信息效应与资本效应,对农户参与农村社区公共物品供给博弈的均衡路径产生重要影响。在独立博弈下,声誉的直接效用能使农户采取合作行动;在关联博弈和重复博弈中,声誉的信息及资本效应对农户的偷懒行为有很强的约束,将导致博弈进入合作均衡。因此基于声誉损益的考虑,由农户自愿供给农村社区内的公共物品会是一个有效的结果。     

市场经济信誉机制的构筑

信誉与市场经济并非对立和互相排斥，相反，信誉是市场经济的基础。良好的信誉可以大大拓宽市场经济的交易范围，大大减少交易费用。产权的明确界定，完善的法治环境和畅通的信息传播机制是建立良好的信誉的必要条件。     

中国国有银行的资本金谜团

本文旨在考察中国国有银行资本金谜团的由来 ,并为破解该谜团提供一种可能的视角。本文的讨论表明 ,国有银行之所以能在真实资本极少得到补充且不良贷款比率居高不下的情况下保持稳定 ,是因为国家与居民在中国特殊的改革背景下建立起了一种奇妙的资本联盟。由于在这种联盟中 ,国家以声誉入股且具有不可分性 ,因此 ,中国国有银行改革的可行方式是谋求改变资产结构 ,而不是试图重组资本结构。     

药价虚高博弈分析

药价问题是关系能否顺利建设和谐社会的大事，“药价虚高”已引起各方高度关注，如何才能根治这个问题呢？本文发现医药定价改革的关键是解决医患之间严重的信息不对称问题，为此本文建立了一个序贯均衡博弈模型，给出了解决医患信息不对称的方法：进行医院专业化及建立医德机制。     

农户声誉对农村借贷市场中逆向选择的约束研究

农户的声誉是信用社借贷决策中主要的考量因素之一.声誉能够反映农户能力与品格的综合信息,那些能力较强、品格好的农户才会有较高的声誉水平.文章利用信号传递博弈模型,阐明在农户与信用社的非对称信息借贷博弈中,农户声誉如何成为信用社识别可信赖的贷款农户的有效信号,从而克服农村借贷中的逆向选择问题.     

Corporate Social Responsibility and Business Value of Multinational Companies: Lessons from a Sub-Saharan African Environment

ABSTRACT

The issue of corporate social responsibility (CSR) as an approach for businesses to independently take actions that lead to better levels of societal development as well as higher value creation for the business, particularly in developing countries has gained much advocacy. Thus, the purpose of this study is to examine the relationship between CSR and business value of multinational companies (MNCs) in sub-Saharan Africa. The study adopted quantitative research methodology and using multiple regression analysis, findings show that CSR can positively and significantly predict business values in the multinational subsidiaries. These values include direct (economic value) and indirect (human capital value and reputational business value). This paper therefore contributes to a novel CSR index from the perspective of business value and sustainability of MNCs in the Sub-Saharan Africa (SSA) environment. Thus, the paper recommends MNCs operating in Africa to enhance their social investment through their CSR strategy with the aim that CSR must not be regarded as a cost center, but an investment instrument that can accrue various dividends.
