Some implications of e-Commerce financial services firms are becoming clear. The web drives transparency, and increases the information endowment of all market participants. It is harder to manipulate customers' behavior, or to overcharge them. Transparency drives differential pricing. Not all customers can or should be charged the same prices. Transparency reduces the viability of cross-subsidies between customers can or between products. The differential pricing enabled by the web transforms distribution channels, and enables direct distribution and alternative forms of distribution. Some intermediateraries may be bypassed altogether, while others may rapidly lose their best, most profitable, and previously most loyal customers. 相似文献

We extend prior research on the empirical properties of daily trading volume and methods to detect abnormal trading volume in two ways. We compare the performance of a nonparametric test statistic with the parametric test statistic used in prior research and we study samples of NASDAQ securities as well as samples of NYSE/ASE securities. Prior research has focused exclusively on NYSE securities. We find the nonparametric test statistic is more powerful in detecting abnormal trading volume than the parametric test statistic in both samples of NYSE/ASE and NASDAQ securities. We also document that abnormal trading volume will be detected more often in samples of NYSE/ASE securities compared to NASDAQ securities. 相似文献

Images of the future are essential to a society's survival. According to Polak [1], images of the future reflect and foreshadow society's future; as images go, so goes society. As a visual medium, cities in particular depend on robust images of the future. I submit that our ability to develop useful images of future cities depends on our visual literacy in understanding architectural images. This study explores alternative futures illustrated with future fantasies as an experiment in connecting images, archetypal myths, and alternative futures. Using two variables (strength of the economy and shifts in social values), four scenarios are proposed: Frontier Freedoms, Urban Fortress, Eco-Survival, and Utopian Hopes. Scenarios of future cities depicted by architectural imagery and linked to worldviews and archetypal myths broaden public discourse beyond economics and technology to address qualitative contextual factors such as identity, community, sacredness, and nature. 相似文献

It is well documented that individuals do not spend the Supplemental Nutrition Assistance Program (SNAP) benefits smoothly over the month after receipt. Rather, recipients spend a disproportionate share of benefits at the beginning of the benefit month. This has costs for recipients and stores. There is also evidence that other income streams, such as Social Security and paychecks, are not spent smoothly. The presence of these other income streams may bias estimates of the effects of this SNAP cycle on consumption for working SNAP beneficiaries and those who receive other government benefits. We use data from United States Department of Agriculture's National Household Food Acquisition and Purchase Survey to explore how the SNAP cycle is affected by accounting for these other income streams. We find suggestive evidence that the cycle is more pronounced for workers who are paid on a weekly or monthly basis, but little evidence that cycles in other income streams mitigate or exacerbate the SNAP cycle. 相似文献
