Intraday jumps and US macroeconomic news announcements 总被引:1,自引:0,他引:1
Kevin P. Evans 《Journal of Banking & Finance》2011,35(10):2511-2527
This paper applies recent non-parametric intraday jump detection procedures to investigate the presence and importance of intraday jumps in US futures markets. More importantly, the paper investigates the extent to which statistically significant intraday jumps are associated with US macroeconomic news announcements. Jumps are prevalent, large and contribute heavily to total daily price variation. Approximately one third of jumps correspond to US macroeconomic news announcements, with pure announcement effects causing large increases in the absolute sizes of jumps and the informational surprise of the announcement explaining large proportions of the jumps. The statistical and economic significance of news-related jumps is confirmed by results that show higher volatility persistence, predictability of lower frequency returns, larger effects on microstructure variables, jump clustering and co-jumps from these jumps versus non-news-related jumps, although there are some interesting variations across asset classes. 相似文献

Educators continue to utilize add-ons, extensions, or replacements to traditional Learning Management Systems (LMSs) to supplement capabilities and improve the classroom experience. This work resulted in the design and development of the Education Dashboards for Enhanced Learning (EDEL) template. The EDEL template enables faculty members to create dynamic web spaces called Knowledge Portals (KPortals). A semester-long introduction of KPortals proved to be positive and useful. Students tended to view the KPortal as a “go-to” webspace. The authors hope to refine the template in future studies and examine its usefulness in other countries. 相似文献

This paper advances the conception of social entrepreneurs as caring entrepreneurs. We argue that the care ethics of social entrepreneurs, implying the pursuit of caring goals through caring processes, can be challenged when they engage in the process of scaling up their ventures. We propose that social entrepreneurs can sustain their care ethics as the essential dimension of their venture only if they are able to build a caring enterprise. Organizational care designates the set of organizing principles that facilitate the embedding of care ethics at an organizational level, beyond the imprinting induced by social entrepreneurs’ personal ethics. 相似文献

We investigate how firms strategically vary their disclosure policies in response to labor unemployment concern. Using changes in state unemployment insurance laws as exogenous variations of labor unemployment concern, we show that firms provide more bad news forecasts when unemployment concern is low. This relation is stronger when firms are financially constrained, when CEOs and CFOs have higher equity incentives, and when workers are likely to be affected more by unemployment. Our findings are not driven by earnings management reversal or underlying performance changes, and are robust to a battery of identification tests. Finally, we find a similar effect of unemployment concern on disclosure using the tone of 10‐K and 10‐Q filings as an alternative proxy for corporate disclosure. Overall, our findings suggest that labor unemployment concern is an important consideration for corporate discretionary disclosure. 相似文献

We use a version of the Global Projection Model covering the United States, Euro area and Japan to assess options for dealing with the looming risk of international deflation. The zero floor to interest rates constrains monetary policy. Confidence intervals, derived from stochastic simulations, indicate ranges of uncertainty. The results suggest a high probability of a declining price level for a couple of quarters in 2009. Suitable policy adaptations reduce the risk that this might turn into a prolonged, global deflation. These include: a price level path target for monetary policy, which would respond to previous, as well as expected, shortfalls from the desired inflation rate; a more stimulative fiscal policy; and an increase in the long-run target for inflation. 相似文献

This paper analyses contemporary tourism management issues in India’s national parks. It begins by setting India’s national parks in the context of national parks globally, before examining the historical development of national parks in India itself. Based upon the author’s extensive qualitative research, the paper then discusses in general terms the tourism conflicts that have recently emerged in India’s national parks. It goes on to examine in detail the tourism management issues as they apply to a specific case study, namely the Rajiv Gandhi (Nagarahole) National Park located in the state of Karnataka. It is concluded that the voices of indigenous communities needs to be recognised in the management of the park and in terms of tourism development efforts. 相似文献

Does the presence of corporate headquarters in a city affect the incomes of local charities? To address this question we combine data on the head office locations of publicly traded U.S. firms with information on the receipts of local charitable organizations. Cities like Houston, San Jose, and San Francisco gained significant numbers of corporate headquarters over the past two decades, while cities like Chicago and Los Angeles lost. Our analysis suggests that attracting or retaining the headquarters of a publicly traded firm yields approximately $3–10 million per year in contributions to local non-profits. Likewise, each $1000 increase in the market value of the firms headquartered in a city yields $0.60–1.60 to local non-profits. Most of the increase in charitable contributions is attributable to an effect on the number of highly-compensated individuals in a city, rather than through direct donations by the corporations themselves. The increased private sector donations from the presence of corporate headquarters do not seem to crowd out government grants to local charities. 相似文献

在"多中心"理论之前,社会上主要存在市场秩序和国家主权秩序.多中心的产生源于集体行动理论的局限性,它颠覆了公共财产只有交由中央权威机构管理或完全私有化后才能有效管理的传统观念.本文对当代公共选择学派和公共经济学的代表人物埃莉诺·奥斯特罗姆的"多中心"理论做了解读,并从奥斯特罗姆个人学术研究经历出发,追溯多中心思想形成的全过程,最后就"多中心"理论的重要意义与发展方向做了展望. 相似文献

We provide empirical tests of a general version of targeting theory that greater scrutiny could lead to executive abuses. Our results show that new CEOs under higher expectations or pressure are more likely to report meeting analyst forecasts; however, this apparent superior performance dissipates after excluding firms having characteristics synonymous with earnings manipulation. We find evidence that new CEOs under greater pressure are considerably more likely to engage in manipulation while the link between expectations and manipulation is much weaker. The results are strongest for new CEOs whose firms report meeting forecasts and do not “walk down” earnings estimates. 相似文献

We find that, from 1970 to 2006, the GDPs of 181 countries are described by a log-normal with a power law tail before 1992, but by a kinked power law distribution after 1992. In the 15 years from 1992 to 2006, there are two obvious scale-free zones for annual GDPs, ranked from the largest to smallest. If the countries in each scaling region are regarded as a group, the world is divided into two groups, each with a roughly stable number of members. The power exponents of the two groups are different and hence lead to different inequalities. Therefore, the basis for classification is the macro-consistent inequality within each group. The wealth grows in a synchronous nonlinear manner within groups that have a stable wealth distribution and rank structure. If each group is considered as a club, we name it a ‘synchronization club’. 相似文献
