网络组织流程协同效应的生成机理研究

文章主要对网络组织流程协同效应的生成机理进行深入研究。鉴于学术界对网络组织流程没有统一的认识，文章在文献分析和逻辑推理的基础上，首先明确界定了网络组织流程的内涵，进而构建了网络组织流程协同效应的概念模型，最后应用多层次回归分析对所采集的数据进行实证分析，验证网络组织流程协同效应的研究假设。结果表明，网络中结点企业间的关系强度正向影响流程协同效应，而网络组织的治理机制在关系强度与流程协同之间起着调节作用，跨组织信息系统起着部分调节作用。该结论对于网络组织的治理实践具有一定的理论和现实意义。

Media coverage and investment efficiency

We examine the effect of media coverage on firm-level investment efficiency. We find that media coverage reduces under-investment but increases over-investment. The negative effect of media coverage on under-investment is more pronounced in firms affected by greater information asymmetry and poorer corporate governance. The positive effect of media coverage on over-investment is driven by media-induced CEO overconfidence. Additional results show that both investment- and non-investment-related news coverage decrease under-investment, while non-investment-related news coverage is more influential in increasing over-investment. In general, higher news optimism is associated with less under-investment but more over-investment. Moreover, media coverage affects investment efficiency through its information dissemination rather than information creation function. Collectively, our results suggest that firms’ media visibility promotes more over-investment than under-investment.     

Private information in currency markets

Using daily abnormal currency returns for the universe of countries with flexible exchange rates, we show local currency depreciations ahead of unscheduled, public sovereign debt downgrade announcements. Consistent with the private information hypothesis, the effect is stronger in lower institutional quality countries and holds after we control for concurrent public information and for publicly available rumors about the forthcoming downgrades. Our results persist when abnormal currency returns are adjusted for global carry and dollar risk factors, world equity and bond returns, as well as local stock market returns. Finally, the currency depreciations are permanent, providing evidence for a link between fundamentals and currency markets.     

基于专利信息的产业技术竞争优势测度模型构建与实证研究

提出产业技术竞争优势的概念，并探讨其"规模-质量-价值"三维模型和测度指标体系；构建产业技术竞争优势指数，利用熵值法设置权重，采用合成指数法计算产业技术竞争优势指数。以世界生物医药产业主要国家（中、美、德、日）1996-2016年样本数据进行实证研究。结果表明：中国生物医药产业技术竞争优势指数及分指数总体保持上升趋势，其中规模指数增长较快，价值指数次之，质量指数发展居于末位；美国、日本和德国竞争优势指数相近，均具有较强的竞争优势；中国产业技术竞争能力处于劣势地位，规模维度方面中国与其它三国差距较小，价值维度差距次之，质量维度差距较大。     

家族控制与企业创新投入

家族企业对社会情感财富目标的追求是其区别于非家族企业的重要特性，社会情感财富目标与企业经济利益间冲突对企业R&D投入的影响不容忽视。以社会情感财富为理论基础，基于573家上市家族企业2011-2015年的面板数据，分析受市场化程度影响时，家族涉入情境下信息透明度对企业R&D投入的影响。结果显示：信息透明度可以有效缓解信息不对称和代理冲突，促进企业R&D投入；家族控制对R&D投入有消极影响；当企业信息透明度较高时，会抑制家族所有者为个人谋取私利的动机，进而增强其对企业R&D投资的积极作用。在市场化程度更高、产权保护力度较大的地区，信息透明度会缓解家族控制权对R&D投入的消极作用。     

Mandatory IFRS adoption and management forecasts: The impact of enforcement changes

We examine how concurrent enforcement changes affect the positive relationship between mandatory IFRS adoption and firms’ voluntary disclosure. We show that the increase in the issuance of management forecasts after IFRS adoption is smaller for firms from IFRS-mandating countries with concurrent enforcement changes than for those from countries without such changes. We find no difference in the increase of forecast informativeness between firms from IFRS-mandating countries without concurrent enforcement changes and firms from non-IFRS-mandating countries; however, firms domiciled in IFRS-mandating countries with concurrent enforcement changes exhibit a significantly smaller increase in forecast informativeness. Our findings suggest that better IFRS enforcement distinctly weakens (strengthens) the positive effect of IFRS adoption on voluntary (mandatory) disclosure.     

Reverse Payments and Risk of Bankruptcy Under Private Information

Abstract

In the pharmaceutical industry, a reverse payment (pay-for-delay) is a payment from an originator to a generic producer to delay her entry. In some recent cases, the US and EU antitrust authorities have banned these agreements per se, while in others they have used a rule of reason. This paper analyzes their dynamic effects and shows that a ban per se may reduce consumer surplus when the generic producer may go bankrupt and her financial situation is private information. Reverse payments are more beneficial when competition among few players is soft, the economy is in a downturn, and the period of drug usage after patent expiry is long. Results suggest that a rule of reason is more suited than a ban per se.
