This article uses a nonparametric test based on the arc‐sine law (see, e.g., Feller, 1965 ), which involves comparing the theoretical distribution implied by an intraday random walk with the empirical frequency distribution of the daily high/low times, in order to address the question of whether the abandonment of pit trading has been associated with greater market efficiency. If market inefficiencies result from flaws in the market microstructure of pit trading, they ought to have been eliminated by the introduction of screen trading. If, on the other hand, the inefficiencies are a reflection of investor psychology, they are likely to have survived, unaffected by the changeover. We focus here on four cases. Both the FTSE‐100 and CAC‐40 index futures contracts were originally traded by open outcry and have moved over to electronic trading in recent years, so that we are able to compare pricing behavior before and after the changeover. The equivalent contracts in Germany and Korea, on the other hand, have been traded electronically ever since their inception. Our results overwhelmingly reject the random‐walk hypothesis both for open‐outcry and electronic‐trading data sets, suggesting there has been no increase in efficiency as a result of the introduction of screen trading. One possible explanation consistent with our results would be that the index futures market is characterized by intraday overreaction. © 2004 Wiley Periodicals, Inc.

The development of a fast and reliable Internet, new technologies online payment systems, and changes in work structure that enable and demand flexible working patterns have driven a move to a new form of Internet‐enabled labour exchange called crowdsourcing. Evidence from an in‐depth qualitative study is presented, focusing on selected users' interactions and experiences of working on two UK‐based crowdsourcing platforms. The paper shows that workers engaged in this form of labour exchange need to deploy existing employability skills and networks to effectively meet the challenges, and take advantage of the opportunities, that crowdsourcing presents. Individual factors and circumstances emerge as paramount for workers' continued engagement in this form of employment. Using selected components from an employability framework, the findings suggest that crowdsourcing can offer new pathways to practising skills and enhancing employability for some workers. 相似文献

To gain a better understanding of online brand communities, this study has examined why people joined in online brand communities and whether there were some differences in the motivations of Internet users based on different cultures. Open-ended questions were asked to the community members from both South Korean Automobile Online Brand Communities (KAOBC) and American Automobile Online Brand Communities (AAOBC) in the first stage and then generated and utilized an online survey for the study. The study found that KAOBC members tended to have a stronger social network, business, and communication motivations than AAOBC members. As a primary motivation, information seeking is the strongest motivation for members of both KAOBC and AAOBC. They had a similar level of information motivation. 相似文献

This study investigates the relational factors and motivations of Chinese migrant consumers towards financial service providers in New Zealand. Using convergent interviews, a deeper understanding is developed of immigrants’ relational behaviour with service providers. These relationships with service providers are significantly influenced by traditional Chinese values and guanxi and relational embeddedness plays an important role in how they are developed. The research contributes a better understanding of the interplay between Eastern and Western cultures in service relationships among immigrant groups. A general theory of the Chinese perspective of customer relationship management is developed. The implications for how marketing practitioners manage their relationships with migrant customers are explored. 相似文献

In this paper we present estimates of the responses of individuals to marginal tax rates in their reporting of income, using
data from individual tax returns for the year 1995. One estimation method is ordinary least squares regression. A second method
uses quantile regression, which provides evidence on behavioral responses at different points (or quantiles) in the distribution
of income and so is relevant to the question of whether the responses of, say, the rich differ from those at other points
in the income distribution. Our results clearly indicate that marginal tax rates affect the reporting decisions of individuals.
However, there are significant differences in the marginal tax rate reporting responses for the various types of reported
income, there are major differences across income classes, and there are notable differences in the estimated responses across
estimation methods.

Changes in Europe resulting from the unification of EC countries and the accessibility of new Eastern European markets have fundamentally altered the trading environment in which advertising agencies operate. As the advertising industry attempts to get to grips with legislative and media changes, agencies are working hard to create alliances and develop networks which encompass markets in which they did not traditionally have a presence. This article draws on a combination of quantitative and qualitative information collected from secondary sources and extended personal interviews with key agency personnel, advertisers and representatives from the UK's Advertising Association and The Advertising Standards Authority. The objective is to show how the advertising industry and agencies are continuing to gear up to meeting the new demands of the Europeanized market. 相似文献
