The impact of country risk ratings on U.S. firms in large cross-border acquisitions

This study investigates the impact of country risk ratings on the wealth gains to large U.S. bidders involved in cross-border acquisitions. The findings indicate that U.S. bidders experience positive wealth gains during the merger announcements, though this is concentrated in transactions involving European targets. There are also differences in wealth gains to bidders with respect to industry classification and location of foreign targets. The country risk factors including economic, political, and financial risk ratings all play a significant role in explaining the wealth gains to bidders. Furthermore, the wealth gains are higher for the firms with acquisitions in developed countries and are significantly related to GNP growth rate.     

Effects of Transparency in Procurement Practices on Government Expenditure: A Case Study of Municipal Public Works

This paper examines the effect of improved transparency in the bidder qualification process, using the experience gained from a case study of municipal public works auctions. A difference-in-differences analysis reveals that improved transparency reduces procurement cost by up to 8%. This finding is robust with regard to the concerns of both endogeneity and sample selectivity. The bidding-function estimates, combined with features of Japanese procurement system, imply that the introduction of transparent practices is insufficient to bring about efficiency in public procurement.

Performance Volatility and Wage Elasticity: An Examination of Listed Chinese A-share Enterprises

The management of future financial risk on the part of managers and changes in firm finances are two of the fundamental reasons for upward and downward rigidity of wages. The proxy variable for firm financial risk is volatility, the past performance of which is among the principal indicators of wage rigidity. In firms whose current performance is on the upswing, the greater the volatility in past performance, the smaller the elasticity ratio and the more acute the upward rigidity; the more stable past performance, the larger the elasticity ratio and the more acute the upward elasticity. In firms in which current performance is declining, greater past performance volatility leads to a larger elasticity ratio and more acute downward rigidity, whereas more stable such performance leads to a smaller elasticity ratio and more acute downward rigidity.

Linear Correlation and EVT: Properties and Caveats

Due to the current credit crisis, critical questions are beingasked concerning some of the quantitative methods used in riskmanagement under the Basel II proposals. In this paper I havegiven a critical look at Extreme Value Theory and Copulas. Boththeir potential applications and the possible caveats are discussed,and this mainly with the subprime crisis as a background.     

Hedge funds and financial stability: Regulating prime brokers will mitigate systemic risks

We review key characteristics of the hedge fund industry, and identify conditions under which this sector can pose a threat to financial stability. Direct regulation of hedge funds that increases transparency does not appear feasible, may create a moral-hazard problem, and may reduce market liquidity. Indirect regulation by prime brokers and market discipline by creditors, counterparties, and investors have been effective in limiting the risks from the hedge fund sector. To reduce systemic risks, more regulation of prime brokers is warranted to avoid competitive dynamics from undermining counterparty risk management practices.

供应链管理环境下军用物资多品种采购的多供应商选择研究

为解决供应链管理环境下军用物资采购多供应商选择问题,建立了以供应综合成本最低为目标函数,满足多个约束条件的组合优化模型。为解决求解的困难,采用变换分解算法,将原模型转换为整数规划问题。根据不同迭代方式,给出了两种基本运算步骤。算例分析表明:该新方法克服了常规供应商选择评价方法只针对单一物资供应过程和面向单一供应商选择过程的局限性。
