HOW DO RATING AGENCIES’ DECISIONS IMPACT STOCK MARKETS? A META‐ANALYSIS

The purpose of this study is to examine how credit rating agencies’ decisions impact the stock market using a systematic and quantitative review of existing empirical studies. Specifically, we employ a meta‐regression analysis (MRA) to investigate the extent and nature of the effect of rating agencies’ decisions on the stock market. We survey 62 studies published between 1978 and 2015. Our first finding is that the cumulative average abnormal returns calculated from this empirical literature are affected by publication bias. After controlling for publication bias, the main findings of our meta‐analysis indicate that negative rating decisions cause statistically significant negative abnormal returns. This evidence suggests an informational effect. Our results also indicate that positive rating decisions do not have a significant effect. Finally, the MRA results reveal the importance of several factors related to primary study design, as well as to the nature of the data.     

Hybridization: Understanding the microdynamics of a postacquisition integration process

There is no shortage of theoretical or empirical research on mergers and acquisitions (M&A). Knowledge on the subject has grown substantially in recent decades. However, the integration of firms involved in M&A remains a challenging and often unsuccessful process. In addition, there is a scarcity of research on temporal dynamics within integration projects. This article reports on the postacquisition integration of a business school into a university using the concept of organizational hybridization as a theoretical lens. The aim was to identify the microdynamics that occurred during integration. We conducted an inductive case study, interviewing professionals involved in the integration process, analyzing a wide range of documents, and conducting participant observation over 6 years. Field research revealed that different organizational components underwent distinct hybridization processes that were characterized by different degrees of conflict. This study contributes to the understanding of the microdynamics that occur in postmerger or postacquisition integration processes, focusing on the complex adjustments inherent in these developments.     

我国知识产权壁垒研究现状及成因、对策简析——基于文献计量学的视角

随着针对知识产权壁垒研究的开展,学者们当前的研究热点及现状成为需要关注的方向。本研究基于文献计量学的视角,对2005.01-2015.03间CSSCI期刊中收录的以知识产权壁垒为研究主题的研究论文进行统计与关键词归类,并利用Ucinet软件,对知识产权壁垒的研究现状展开分析。研究结果显示,关于知识产权壁垒的研究尚处于起步阶段,研究热点主要集中于知识产权壁垒的定义与表现形式、337调查及应对策略等,而对于知识产权壁垒的成因分析却涉及较少。因此,本文继续以337调查事件为基础,结合我国现实,对知识产权壁垒形成的原因进行归纳,最终为打破知识产权壁垒提供了相应的对策建议。     

Considering the nuclear option: Hidden benefits and social costs of nuclear power in the U.S. since 1970

Although burning fossil fuels has environmental consequences, many countries have switched away from nuclear power in favor of fossil-fuel fired electricity production after incidents at Three Mile Island, Chernobyl, and Fukushima. This study estimates the substitution between nuclear and fossil-fuel fired electricity generation in the United States. Using an event-study framework, we leverage nuclear plant openings from 1970 to 1995 and forced nuclear plant outages from 1999 to 2014. Plant openings (nuclear outages) reduce (increase) monthly net coal-fired generation by approximately 200 GWh, implying a considerable reduction (increase) in emissions. We find that the substitution between nuclear and coal is not one-to-one, as has been assumed in prior literature. After establishing these stylized facts, we explore the potential underlying forces driving the observed substitution between coal and nuclear.     

高质量发展视角下区域创新能力的提升路径 ——以南京市江宁区为例

我国经济已由高速增长阶段转变为高质量发展阶段,实现高质量发展是新时代我国经济发展的根本要求。高质量发展与创新驱动紧密关联,必须多举措协同提升区域创新能力。区域创新能力是指一个地区将知识转化为新产品、新工艺、新服务的能力,代表了创新要素在一定区域内聚集、整合以及推动区域可持续发展的基本能力。为了有效提升区域创新能力,必须强化区域创新的综合保障、构建区域创新综合生态体系、促进创新创业项目孵化与成果转化、强化区域制造业发展相关的创新活动等。以南京市江宁区为例对此进行了分析,该区积极实施战略科技引领计划,不断强化创新工作,通过促进区域创新平台建设、区域创新的服务支撑体系构建、高端创新资源在区域的聚集、区域制造业创新发展及合理布局等,不断增强区域创新能力,有效支撑了区域高质量发展。     

Moving markets? Government bond investors and microeconomic policy changes

Do sovereign bond markets react systematically to microeconomic policy reforms? Some observers suggest that investors are very attentive to supply‐side policies such as those related to labor markets, corporate taxation, and product standards. They argue that, along with macroeconomic outcomes and broad financial market conditions, such reforms affect sovereign bond premiums, for developed as well as emerging economies. In contrast, we predict few systematic effects of supply‐side policy reforms on sovereign bond market outcomes. Our theory draws on a standard three‐equation model of the economy, widely accepted among economic and finance professionals. That model makes few clear predictions regarding the anticipated effects of microeconomic policy changes; as a result, we expect that such reforms will not generate systematic market reactions. Our analyses, based on daily data from 37 countries from 2004 to 2012, indeed reveal little evidence of a systematic bond market reaction to the 47 most significant reforms to corporate taxation and labor market regulation. These results call into question the notion that “bond market vigilantes” play a central role in compelling governments to enact specific microeconomic policy changes.

大断面强流变软岩硐室加固技术相似模拟试验研究

针对鹤煤九矿井下硐室出现浆皮开裂、底臌等类似现象,采用相似模拟的方法,以鹤煤九矿31采区避难硐室临近硐室群实际地质资料为基础,研究分析了给定应力环境下不同支护方式时硐室围岩的变形破坏情况、失稳过程。作者认为,随着顶部压力的逐渐改变,顶板裂隙逐渐增加,裂隙深度和宽度逐步增加,巷道出现离层、底鼓,进而呈现大面积破坏。该结果对区段巷道布置与加固方案优化有一定的参考价值。
