对项目评估中＂生产负荷＂问题的探讨

一、现行项目评估方法存在的缺陷 所谓“生产负荷”，是指投产项目某一年度的产品产量与年设计生产能力之比。在评估固定资产贷款项目时，需预测项目投产后各年的生产负荷，并据此测算每一年度的成本和收益情况，     

网络智能化管理的规划与实现

随着商业银行数据的日益集中,计算机网络在商业银行的应用越来越广泛,从日常对外营业系统、OA办公系统、财务报表分析系统到决策支持系统都离不开网络。网络规模的日益庞大使得网络管理维护的工作量呈几何级数增加。传统的网络管理系统主要是对被管理设备进行工作性能指标的收集、观测、统计等,是一种被动式、后置式的管理。如今,这种依靠个人经验的手工管理方式已不能满足实际需要。如何利用计算机软件管理网络,提高网络设备的利用率、可靠性和性能服务质量等是科技部门要解决和改善的问题。本文对在网络智能化管理中引入专家系统、实现网…     

基层央行改善网络环境的几点建议

根据等级保护要求，地市中支的网络设备需定级为二级，如何对网络环境进行改造，使网络设备安全满足二级要求。笔者以所在中支进行网络等级保护采取的措施，谈谈基层央行实施网络保护的几条建议。     

一种网络动态热备的配置与实现

随着网络的日益发展,网络在计算机系统应用中所起的作用越来越大.特别是实时性强的业务系统,其数据要求在网络上进行不间断传输,对网络的可靠性和不间断性提出了很高的要求.以前网络设备为冷备份,网络线路未实现动态热备时,一台网络设备如出现故障要手工更换上冷备设备,网络很难保持高可靠性和不间断性.     

利用网络监控系统提高网络服务水平

随着浦发银行大连分行各项业务的逐步发展，支行和自助网点数目大幅提高。随着分行网络规模的加大，网络维护工作的重要性日益彰显。2006年7月，总行推出网络集中监控系统，该系统通过使用snmp协议采集网络设备信息，通过对信息进行分析加工，得出细节情况进行相关处理。在监控内容上，主要针对网络设备内存、CPU使用情况，指定的端口状况，线路误码率以及网络协议变动等诸多项目进行监控，对使用率超过阀值等异常状况进行及时反馈，缓解了网管人员的维护压力。     

Debt and Taxes and Uncertainty

With a graduated personal tax schedule, Miller showed that there could be an equilibrium debt supply for the corporate sector as a whole. In the presence of uncertainty there is also a unique debt/equity ratio for each individual firm, and this ratio is related to the firm's operational risk characteristics. However, if firms merge and spin off in response to tax incentives, the identity of firms is ambiguous and only the corporate sector is a meaningful construct. These arguments are developed in both discrete and continuous models that employ extensions of the arbitrage-free pricing theory.     

教育与资本怎样的前景怎样的现实

来自政府的声音: "动员各种社会资源,发展教育" 此次论坛上财政部长助理张少春的发言是最受关注的发言之一.他的演讲传达出的信息有这样几方面:第一,谈到现实,他认为全社会对教育的巨大需求与我国公共投入不足已成为我国教育事业发展的突出矛盾.近年来,以公共部门投入为主,多渠道筹措教育经费的教育投入机制成为解决这一问题的重要途径,也使得公共部门与私营部门在教育领域的合作日益密切.第二,谈到前景,他认为,1.中国经济持续、快速的增长对高技能人才产生巨大的需求,这为私营部门的参与提供了广阔空间.2.随着公共财政职能的不断完善,财政资金将在各项教育事业中重新进行分配,进一步优化财政支出结构,提高资金的使用效率.在"十一五"期间,我国将把公共支出的重点转移到农村.我们将逐步把全体农村适龄儿童的义务教育全部纳入公共财政体制.     

East and west and north and south : A preliminary model

The Brandt report and other proposals for a new North-South world order continue to be the focus of lively debate, yet it is often argued that little concrete has emerged from their recommendations. A major reason for this, the author argues, is that the East-West conflict component is not sufficiently taken into consideration-East-West tensions are a severe constraint on and a determining factor of North-South relations. Using influence diagrams, the author develops a flexible framework for discussion and assessment of N/S-E/W relations.     

Director gender and mergers and acquisitions

Does director gender influence CEO empire building? Does it affect the bid premium paid for target firms? Less overconfident female directors less overestimate merger gains. As a result, firms with female directors are less likely to make acquisitions and if they do, pay lower bid premia. Using acquisition bids by S&P 1500 companies during 1997–2009 we find that each additional female director is associated with 7.6% fewer bids, and each additional female director on a bidder board reduces the bid premium paid by 15.4%. Our findings support the notion that female directors help create shareholder value through their influence on acquisition decisions. We also discuss other possible interpretations of our findings.     

Political corruption and mergers and acquisitions

This research examines the relation between political corruption and mergers and acquisitions (M&As). We find that local corruption increases firm acquisitiveness but decreases firm targetiveness. The levels of corruption in acquirer areas relate positively to the bid premiums and negatively to the likelihood of deal completion. Corruption motivates acquiring firms to use excess cash for payment, which mitigates the negative effect of corruption on acquirer shareholder value. The evidence indicates that acquisitions help acquiring firms convert cash into hard-to-extract assets and relocate assets from the high to low corruption areas, thereby shielding their liquid assets from expropriation by local officials.     

Trust and cross-border mergers and acquisitions

A number of studies suggest that social trust matters for investment. Using different measures of trust from World Values Survey, we show that countries where people display higher levels of trust engage in more cross-border M&A activities. When they do, these acquirers pay lower premiums. To the extent that these acquirers also tend to engage in larger acquisitions as well, our findings suggest that a larger selection pool of potential targets and higher value targets enable these acquirers to negotiate for lower premiums. We do not find evidence of the significant effect for target country trust levels. Hence, trust may benefit those acquiring firms in cross-border transactions.     

Tournament-based incentives and mergers and acquisitions

This research examines the relation between tournament-based incentives, which are proxied by the difference between a firm's CEO pay and the median pay of the senior managers, and mergers and acquisitions (M&As). We find that tournament-based incentives are positively related to firm acquisitiveness and acquiring firms' stock and operating performance. Further analysis indicates that positive acquisition performance increases the likelihood of the CEO being promoted from inside the acquiring firm. Our evidence is consistent with the view that tournament-based incentives motivate acquiring firms' managers to make greater efforts and take more risk that result in superior acquisition performance.     

Corporate Innovations and Mergers and Acquisitions

Using a large and unique patent‐merger data set over the period 1984 to 2006, we show that companies with large patent portfolios and low R&D expenses are acquirers, while companies with high R&D expenses and slow growth in patent output are targets. Further, technological overlap between firm pairs has a positive effect on transaction incidence, and this effect is reduced for firm pairs that overlap in product markets. We also show that acquirers with prior technological linkage to their target firms produce more patents afterwards. We conclude that synergies obtained from combining innovation capabilities are important drivers of acquisitions.
