Merger and acquisitions in South African banking: A network DEA model

Banking in South Africa is known for its small number of companies that operate as an oligopoly. This paper presents a strategic fit assessment of mergers and acquisitions (M&A) in South African banks. A network DEA (Data Envelopment Analysis) approach is adopted to compute the impact of contextual variables on several types of efficiency scores of the resulting virtual merged banks: global (merger), technical (learning), harmony (scope), and scale (size) efficiencies. The impact of contextual variables related to the origin of the bank and its type is tested by means of a set of several robust regressions to handle dependent variables bounded in 0 and 1: Tobit, Simplex, and Beta. The results reveal that bank type and origin impact virtual efficiency levels. However, the findings also show that harmony and scale effects are negligible due to the oligopolistic structure of banking in South Africa.     

打破我国出口信用保险垄断模式的思考

本文从我国出口信用保险的发展现状出发,借鉴国际经验,针对我国国情,对其中已符合市场化运作条件的短期出口业务,分析其商业化优势并思考解决策略及具体步骤。在保持中国信保现有的行业主导模式下,若能针对其中已经发展比较成熟而符合市场化运作条件的短期业务部分,放开一部分市场进入壁垒,允许有条件经营这部分业务的商业保险公司针对严重供需不平衡的中小企业拓展业务,将开发巨大的潜力市场,增进社会福利。     

商业银行引入战略投资者定价行为分析

本文主要分析了商业银行引入战略投资者时,战略投资者与商业银行对所参股的定价问题。通过分析,得出在不同边际成本条件下,商业银行股份的定价在边际成本不变条件下战略投资者所支付的价格高于城市商业银行股份的实际价值,该价格会落在一定的价格区间内,而在边际成本可变的条件下战略投资者和城市商业银行将会达成一个最优定价,当存在投资限制时战略投资者往往会选择投资至最高上限。

商业退回逆向物流网络优化模型研究

针对如何使商业退回成本最小,文中建立了一个数学模型,将商业退回逆向物流系统用一个由顾客、初始回收点和回收中心三类联结点以及它们之间的运输路线组成的网络来表示。为了验证模型的有效性,文中将模型应用于案例分析,最终根据模型求解结果为案例提供了一个具体的解决方案,对案例的求解结果进行了检验。     

Bank exposure to market fear

We find that increases in implied market volatility (a proxy for market fear) have a significant impact on returns of bank stocks, above and beyond systematic risk proxied by the expected excess market return during a bad economic regime. Large bank returns are favorably affected by increases in implied market volatility during the crisis, while small banks are adversely affected by increases in implied market volatility. We attribute the different effects among the size-categorized bank portfolios to the perception that large banks are protected by too-big-to-fail policies. Within the sample of small banks, the adverse share price response to increased implied market volatility is more pronounced for banks that rely more heavily on non-traditional sources of funds, use a high proportion of loans in their assets, have a higher level of non-performing assets, and have a relatively low provision for loan losses. The adverse effect of negative innovations in implied market volatility on small bank returns during the crisis is primarily driven by exposure of their loan portfolio to weak economic conditions.     

商业银行监管与腐败关系研究

政府是商业银行监管的重要力量。本文讨论了监管权力与监管效率的关系,通过模型和数据的分析,指出监管部门的权力必须得到约束,并应进一步完善监管部门的行政架构和激励制度。另外,加强市场监管和促进信息披露对于完善监管体系具有重要意义。     

民营银行并购国有银行的动机、成本与风险探析

当前,在世界范围内特别是在发展中国家,掀起了一股民营银行并购国有银行的浪潮。这种并购容易产生现金流风险、信息不对称风险、政策诱导性风险、管理效率风险、并购失败风险。民营银行应通过以下措施和方法将风险消除,从而实现并购成功:结合银行实际,选用适合自身发展的并购方式;努力消除信息不对称;优化决策程序;妥善处理好与政府的关系。     

我国商业银行利率敏感性缺口分析

金融自由化的迅猛发展使得中国银行业正面临着严峻的利率风险,识别和衡量利率风险并提升国内商业银行的利率风险管理能力,是我国商业银行利率风险管理面临的迫切问题。本文针对目前我国商业银行在利率市场化进程中所表现出来的特征,以中国工商银行为例通过利率敏感性缺口的方法实证分析我国商业银行目前所处的风险状态,并给出利率风险的防范和规避措施。
