Acquisitions of private vs. public firms: Private information,target selection,and acquirer returns

The acquisition of privately held firms is a prevalent phenomenon that has received little attention in mergers and acquisitions research. In this study, we examine three questions: (1) What drives the acquirer's choice between public and private targets? (2) Do acquisitions of private targets elicit a more positive stock market reaction than acquisitions of public targets, which, on average, destroy value for acquirers' shareholders? (3) Do acquirers gain when their selection of a public or private target fits the theory? In this paper, we argue that the lack of information on private targets limits the breadth of the acquirer's search and increases its risk of not evaluating properly the assets of private targets. At the same time, less information on private targets creates more value‐creating opportunities for exploiting private information, whereas the market of corporate control for public targets already serves as an information‐processing and asset valuation mechanism for all potential bidders. Using an event study and survey data, we find that: (1) acquirers favor private targets in familiar industries and turn to public targets to enter new business domains or industries with a high level of intangible assets; (2) acquirers of private targets perform better than acquirers of public targets on merger announcement, after controlling for endogeneity bias; (3) acquirers of private firms perform better than if they had acquired a public firm, and acquirers of public firms perform better than if they had acquired a private firm. These results support the expectation that acquirer returns from their target choice (private/public) are not universal but depend on the acquirer's type of search and on the merging firms' attributes.

《中国人民银行电子信息系统机房建设规范》的应用实践与体会

随着国家相关标准的更新、安全生产要求的提高、架构转型的内在驱动,以及机房建设技术的不断发展,机房建设要求出现了较大变化,落实最新的《中国人民银行电子信息系统机房建设规范》(Q/PBC 00018-2019)的要求,对人民银行系统机房建设具有很强的指导和实践意义。本文通过对该规范发布后的地市中心支行机房改造案例进行研究,分析机房建设贯标实施的关键点和难点,提出了运用优化德尔菲法提升机房建设贯标实践效果的建议。     

前交叉韧带个性化康复支具的数字化设计

为了帮助膝关节前交叉韧带损伤或断裂患者快速康复,设计了一款个性化康复支具。首先,采用膝关节CT及MRI图像,使用Mimics,3-matic等软件构建了前交叉韧带正常和断裂情况下的三维膝关节模型。其次,利用Ansys软件分析了膝关节屈曲0°,30°,60°,90°时,在固定外载荷作用下内、外侧副韧带和后交叉韧带的应力变化情况。最后,根据最新循证医学证据和临床经验,应用正、逆向建模技术设计了一款针对前交叉韧带损伤的膝关节康复支具,并通过虚拟穿戴支具分析了膝关节组织的受力情况。结果表明：前交叉韧带断裂会显著增加膝关节内、外侧副韧带和后交叉韧带的应力和股骨相对于胫骨的位移。所设计的支具能有效减少膝关节因前交叉韧带断裂而产生的过度位移和其他韧带的应力,对患者康复具有积极的促进作用。     

落实科学发展观的公共收入制度与政策研究

作为政府筹集公共资金的基本制度，政府公共收入制度是国民收入分配的重要工具和调控手段。建立一个规范、合理的政府公共收入制度和机制，是目前我国促进科学发展观贯彻落实的配套条件和保障因素。从现实看，除了要继续调整税制结构，完善税制体系，包括调整流转税税率和结构、改进和完善所得税、开征物业税、改革税收征管体制外，还应当从改革和完善政府非税收入体系，特别是改革地方政府土地出让和土地收入制度，改革和完善资源、环境税费制度，深化政府间财政收入分配体制的改革等方面加大力度，以促进资源节约型、环境友好型社会建设，促进落实科学发展观。     

Participation in Philanthropic Activities: Donating Money and Time

The 1994 Independent Sector Survey of Giving and Volunteering conducted by the Gallup Organization was used to study the propensities with which people are solicited for money or time as well as the probabilities that people will volunteer time or donate money or property, given they have been solicited or not solicited, utilizing a two-stage probit analysis. Forty-five percent of respondents were asked by philanthropic organizations to volunteer time in 1994. Of those, 80% did volunteer. Some 78% of respondents were asked to donate money or property in 1994. Of those, 85% donated some money or property. Human, social, and cultural capital explained those who were solicited to volunteer. The same variables plus income variables determined whom to be solicited for donating money or property. Human, social, and cultural capital and income variables accounted for more variation in the probabilities to volunteer or donate, given respondents were not asked to contribute, than the probabilities to volunteer or donate, given respondents were asked to contribute.

FISCAL MULTIPLIERS DURING THE GLOBAL FINANCIAL CRISIS: FISCAL AND MONETARY INTERACTION MATTERS

This study investigates the fiscal multipliers of 21 Organization for Economic Co‐operation and Development countries during the global financial crisis using panel vector auto regression methodology. Our findings suggest that the 1‐year fiscal multiplier was greater than 1 during the crisis, whereas it was less than 1 before the crisis because of different fiscal and monetary interactions. The combination of expansionary monetary and fiscal policies during the crisis boosted gross domestic product more effectively through internal and external transmissions: investment crowding‐out was limited, and net exports were spurred by the policy interaction. In addition, our results are robust to various specifications. (JEL E61, E63, E65)     

内科重症监护病房耐药鲍曼不动杆菌流行病学分析

目的探讨内科重症监护病房(MICU)耐药鲍曼不动杆菌流行病学。方法收集2011年1月至2013年12月MICU送检的菌株标本637株,进行菌株分离鉴定及药敏试验,再行细菌菌谱及耐药性分析。结果 3年来分离出的鲍曼不动杆菌株占所有分离菌株总数的40.0%。除了替加环素,鲍曼不动杆菌几乎对所有抗生素的耐药率在70.0%以上,且有逐年增加的趋势;对碳青霉烯类耐药率达95.0%以上。结论 MICU鲍曼不动杆菌是主要流行病菌,其耐药率极高,除了鲍曼不动杆菌本身的属性外,还与交叉感染、消毒隔离及抗生素的应用有关。
