Existing studies using low-frequency data have found that macroeconomic shocks contribute little to international stock market covariation. However, these papers have not accounted for the presence of asymmetric information where sophisticated investors generate private information about the fundamentals that drive returns in many countries. In this paper, we use a new microstructure data set to better identify the effects of private and public information shocks about U.S. interest rates and equity returns. High-frequency private and public information shocks help forecast domestic money and equity returns over daily and weekly intervals. In addition, these shocks are components of factors that are priced in a model of the cross-section of international returns. Linking private information to U.S. macroeconomic factors is useful for many domestic and international asset-pricing tests. 相似文献

We document negative stock returns and elevated trading volumes around executives’ early option exercise disclosures post‐SOX, but not pre‐SOX. This stock price reaction is incomplete, and the negative stock price drift is smaller post‐SOX compared to pre‐SOX. We also show effects of media coverage in the stock price response to exercise disclosures in the post‐SOX period. These findings provide evidence that the requirement mandated by SOX to disclose executives’ stock option exercises within two business days, and the increased media coverage, improves investors’ ability to incorporate into stock prices in a timely fashion the information conveyed by these exercises. 相似文献

Do internal (administrative human capital) and external (social capital) resources work to reinforce the effects of each other? Work from multiple disciplines has approached this question, and we advance this literature with a theory of social and administrative resources as potential substitutes for each other in the production of public education outcomes. We argue that social capital benefits some groups more than others and that it interacts with management to improve performance. We therefore expect the benefits associated with social capital to be non-uniform across community groups. Using education as our area of study, we find that social capital offers the most direct and unconditional benefits to white students but that management can use human capital resources to compensate disadvantaged students who may lack support and resources outside of the classroom. We do not find support for the expectation that social capital and human administrative capital reinforce the benefits of each other, but we find evidence that the two resource types are substitutable. This implies that management may substitute human capital resources when social capital is low to benefit public program performance. 相似文献

私募股权基金文献综述 总被引:7,自引:0,他引:7
私募股权基金首先在美国,其次在欧洲大陆和英国,得到了充分的发展。因此对美国和欧洲大陆私募股权基金市场的研究给亚洲新兴经济体,尤其是中国PE产业的发展提供了参考依据。本文首先界定私募股权基金的定义,然后从影响私募股权基金发展的因素、委托人-代理人风险控制、退出模式这三个层面对国内外文献进行梳理,最后对该如何培养有利于私募股权基金发展的外部环境提出了几点建议。 相似文献

实施创新驱动战略,事关经济社会发展和强军兴军进程。科技资源是科技创新的物质基础,随着军民融合的深度发展,承制军品民营企业成为国防科技创新与武器装备科研生产的新生力量,其所拥有的科技资源也成为国防科技创新与武器装备科研生产的重要物质基础。承制军品民营企业科技资源配置效率的高低,直接影响到我国武器装备科研生产水平的高低和国防科技自主创新能力的强弱。利用DEA模型测算了87家承制军品民营企业的Malmquist指数及其分解情况,对承制军品民营企业科技资源配置效率进行了评价分析,最终提出了相应优化建议。 相似文献

Our results show that the post-offering performance of private equity issuers is related to growth opportunities. We find significant long-run underperformance in stock returns following private placements only for firms with high Tobin's q. High-q firms experience not only poor stock price performance but also poor operating performance. Low-q firms, in contrast, do not display significant stock price or operating underperformance. We further examine three potential explanations for this relation: over-investment in assets by managers, investor skewness preference, and over-optimism about earnings prospects. Our results are consistent with the view that investors are overly optimistic about the prospects of high growth firms. 相似文献

In this paper, we consider the possibility of identifying peaceful mechanisms such as bargaining protocols, international
institutions, or norms that can enable countries to settle disputes in the absence of binding contracts. In particular, we
are interested in the existence of mechanisms with zero probability of war. Here, we focus on situations where the countries’
payoffs to war are interdependent or correlated and where efficient settlements are not required but subsidies are unavailable.
Most importantly, countries can choose to go to war at any time and can use information learned from the negotiation process
in making this choice. We characterize the conditions under which no peaceful mechanisms exist and discuss how weakening our
war consistency condition can change this result.
We thank Massimo Morelli, Adam Meirowitz, Hein Goemans and two anonymous reviewers for helpful advice and comments and John
Duggan and Dan Bernhardt for encouraging this direction of inquiry. 相似文献
