We use the financial crisis of 2007–2009 as a laboratory to examine the costs and benefits of teams versus single managers in asset management. We find that when a fund uses complex trading strategies involving the use of CDS team-managed funds outperform solo-managed funds. This may be due to the greater diversity of expertise, experience and skill of teams relative to single managers. During the financial crisis, however, the performance premium of teams becomes negative, which may be because of the slower decision times of teams, which are especially costly during times of rapidly changing market conditions.  相似文献

We revisit the stock market anomaly documented by Thomas and Zhang (2008) and show that the apparent mispricing of information transfers has decayed over time, as the US markets experienced rapid improvements in the efficiency of the underlying price formation processes. Utilizing recent advancements in market microstructure research to estimate firm-specific proxies for market efficiency, we demonstrate that the existence of the overreaction anomaly (where stock prices of late announcers in response to the earnings reported by early announcers in the same industry are negatively related to subsequent price responses of late announcers to their own earnings reports) is specific to an earlier sample period and results from the inefficient incorporation of information into prices, largely attributable to an environment with high barriers to arbitrage. Our results indicate that the pricing efficiency of intra-industry information transfers has increased in the recent years of increased liquidity and markedly higher trading activity.  相似文献

本文利用CHIPS2007数据库,基于随机前沿模型对我国城镇就业市场上劳动力的工资扭曲程度进行测度。研究结果表明:(1)在城镇就业市场上,由于工资扭曲现象的存在,劳动力实际获得的工资要比他们的边际生产率低45%~60%;(2)已婚、子女个数较少、本地、拥有失业保险、男性、大中型企业的劳动力工资扭曲程度要低于未婚、子女个数较多、外来、没有失业保险、女性、小型企业的劳动力;(3)中低工资水平的劳动力工资扭曲程度要比高工资水平的劳动力严重,且中低工资水平劳动力工资扭曲程度的方差更大。由此,本文提出推进就业市场的市场化改革,完善就业市场信息网络,从而减轻劳动力工资扭曲程度。  相似文献

In this paper we study market environments where information is costly to acquire and is also useful to potential competitors. Agents may sell, or buy, reports over the information acquired and choose their trades in the market on the basis of what they learnt. Reports are unverifiable – cheap talk messages – hence the quality of the information transmitted depends on the conflicts of interest faced by the senders. We find that, when information has a prevalent horizontal differentiation component, in equilibrium information is acquired when its costs are not too high and in that case it is also sold, though reports are typically noisy. The market for information is in most cases a monopoly, and there is underinvestment in information acquisition. We also show that regulatory interventions, in the form of firewalls, only make the inefficiency worse. Efficiency can be attained with a monopolist selling differentiated information, provided entry is blocked.  相似文献

经济全球化的大背景下,投资体制、资源和利益分配体制都快速的摆脱原来计划经济的轨道,越来越受市场规律的引导和制约,在投资渠道越来越多元的今天,建设程序也有了很大的不同,这些变革都要求我们在规划过程中打破原来以物质空间规划为重心的规划方式,全方位的革新规划的技术方法和思路.为了在规划过程中真正理解规划实施的最重要因素“市场需求”,我们尝试在同里景区控制性规划中借鉴市场营销等方面的理论,引入市场策划的思想,力求让规划成果兼顾投资方利益以及公共利益,使之在实施过程中具有更高的可行性和可操作性。  相似文献

By profiling demographic characteristics, perceived general adoption attributes, perceived value-based adoption attributes, motivational needs, mass media use, and content interest, this exploratory study examines the nature of four categories of mobile TV adopters — current, potential, continuous non-, and discontinuous user groups. Despite the limited sample size (N = 214), there are some meaningful findings. First of all, the non-adoption rate of mobile TV of the continuous non-, and discontinuous user groups is higher than the adoption rate of the current and potential user groups. Less than half of the respondents (N = 34) who had used TV on a mobile device were unwilling to use it again in the next twelve months, and almost half of those (N = 102) did not have the intention of using it within the coming year. The results suggest that the discontinuous group seems to have been dissatisfied with the actual mobile TV use when compared with their expectations and evaluations, while the potential user group is more likely to have high expectations and positive evaluations before the adoption and use of mobile TV. All user groups were unwilling to pay the fee, despite the current and potential user groups perceiving the exceptional values. No differences were found in the personality trait of innovativeness and mass media use behaviors among the four groups.  相似文献

随着金融市场理论研究和实践检验的不断发展,资本市场的许多基础理论受到了极大的挑战,与现有理论相悖的异象不断涌现。新近兴起的实验经济学为人们研究资本市场提供了一条更为有效的途径。本文分析了实验方法在资本市场研究中的利与弊,介绍了部分资本市场实验的设计过程,并应用该方法分析了风险与收益、资本市场的效率、市场泡沫的产生和破灭、CAPM理论,以及交易制度等。文章指出,在资本市场中运用实验方法进行研究,具有可控性、可比性以及可重复性等优点,为我们对于资本市场诸多理论进行检验提供了可能。在资本市场实验的设计中,我们不但需要考虑实验的各种交易制度,还需要考虑到被试人员的选择、交易资产的确定以及市场信息的设计等很多问题,只有对这些问题进行全面地考虑,才能保证实验结果的可信度,进而为我们对于各种金融理论的检验提供可能。  相似文献

The first goal of the paper is to define the concept of micro-marketing, overcoming the 'specialized' perspectives and definitions that have prevailed so far. Micro-marketing relates to ways of controlling environment complexity, facilitated by information technology and required by highly competitive markets. Such control has three forms: segmentation , which reduces complexity to a controllable number of variables; organization , which absorbs a certain amount of complexity by modelling the structure onto the environment; technology , which explores complexity and dominates it through simplification. The second goal is to demonstrate that micro-marketing can build a sustained competitive advantage. Finally, the theoretical implication of the diffusion of a micromarketing approach in the retailing industry is discussed. The areas of strategy, organization, channel relationships, and customer satisfaction are examined. Should micro-marketing become widespread in the retailing industry, we argue that its final result would be increased welfare for the consumer, as long as retailers capitalize on the power of information and stand as a 'countervailing power' to suppliers in the channel.  相似文献

Abstract

In this paper, we offer some insights about Polish consumers with varying levels of general marketplace expertise, their role in diffusing product information, and their views of advertising. Market mavens are consumers who exhibit heightened interestin and knowledge about the marketplace. Because of their interest in communicating with others about the many aspects of the marketplace, these consumers can play an integral role for companies interested in diffusing marketing information. Our study results indicate that market mavens do indeed exist in Poland and they exhibit similar characteristics to market mavens identified in the U.S. They have more favorable attitudes toward advertising than other consumers. Additionally, they consider advertising as an important source of product and social image information. Although Polish mavens are less critical of advertising being misleading and confusing, they are concerned about advertising promoting materialistic values. Our findings imply that firms doing business in Poland would be well advised to target market mavens because they pay attention to advertising, have favorable attitudes toward advertising, and like to talk about marketplace phenomena with others.  相似文献

运用事件研究法和多元回归法考察 “深化增值税改革”(2018年3月28日国务院常务会议)的市场反应及其影响因素。结果表明:尽管中美“贸易战”对股市产生了较大的负面影响,但投资者仍将“深化增值税改革”视为利好消息,且试点行业的市场反应都显著为正。从市场反应影响因素来看,研发支出越多、融资约束越强的公司市场反应更好。此外,进一步细分公司特征发现,高税收敏感度和高产品市场竞争程度的公司市场反应更加积极,存在超额雇佣且研发支出较高以及不存在超额雇佣但融资约束较高的公司市场反应也更加积极。  相似文献
