This study examines the impact of Regulation Fair Disclosure (FD) on liquidity, information asymmetry, and institutional and retail investors trading behavior. Our main findings suggest three conclusions. First, Regulation FD has been effective in improving liquidity and in decreasing the level of information asymmetry. Second, retail trading activity increases dramatically after earnings announcements but there is a significant decline in institutional trading surrounding earnings announcements, particularly in the pre‐announcement period. Last, the decline in information asymmetry around earnings announcements is closely associated with a lower participation rate in the pre‐announcement period and more active trading of retail investors after earnings releases. 相似文献

The supreme obstacle for sustainable development of natural resources is the scarecity, bottleneck. So how to promote the sustainable utilizing and increase the using efficiency of natural resources is worth studying. This paper suggests that we should improve the model and means of evaluating method and value management based on th~ theory of natural resource compensation. This paper discusses the User Cost Method based on the microeeonomicaspect which can change the evaluating method for natural resources. From the perspective of value managemen model, we should use the User Cost Method to realize the linkage and integration of micro and macro eompensation for natural resources. Based on the evaluating and aecounting idea User Cost Method, this paper presents a theo. retical framework to harmonize and link micro and macro compensation for natural resources. At present, we should seek the new approach and method to manage natural resources, so can we realize the capitalization managemen focusing on the vahte management for natural resources. 相似文献

农产品流通市场化改革,是一个巨大而深刻的制度变迁过程,是效益更高的市场经济制度结构替代计划经济制度结构的过程.正式制度环境与非正式制度环境的协调统一、相互融合是市场经济制度结构得以确立和维持的内在本质要求.农产品流通市场制度变迁的方式只能是在政府领导下局部推进、双轨过渡,体制内与体制外相结合,逐步向市场经济过渡. 相似文献

Evaluation of the performance of GDSSs has been dominated by an experimental and laboratory based approach. Other writers
have argued for evaluation to be based in the “real-world” of decision making teams. The evaluation criteria have tended to
ignore many of the issues that would be paramount for some of the stakeholders in the evaluation process. This article seeks
to explore the criteria that might be used by a wide variety of stakeholders, including developers, facilitators, clients,
key actors, vendors, as well as academics. By drawing together the criteria associated with all of the stakeholders we discover
a broader, and possibly more thorough, framework for evaluation. The evaluation of any particular GDSS in relation to other
GDSSs can then be seen in the context of contingent weighting applied to each of the criteria where each GDSS is able to be
seen in its best light and in relation to its declared aims.
This article argues for a more eclectic and contingent approach to the evaluation of GDSSs which will encourage their future
development to be clearer about purpose and the boundaries of their use. 相似文献
