Making Sense of Marketing Data: Some MIS Perspectives on the Analysis of Large Data Sets

Despite the growth in the size and complexity of corporate data, the technology for analyzing it has not kept up with the advances in data collection, in that managers mostly need to rely on marketing research and information systems experts to generate the analysis and reports they need. We review some useful approaches here from the computer science and information systems fields for the analysis of large data sets, viz. good data organization and the use of flexible analysis tools, for making the analysis more tractable and user-friendly. These methods are increasingly being adopted by practitioners who are hard-pressed to generate business intelligence from large corporate databases. However, the benefits of these approaches may not be confined only to practitioners, and may apply to academic researchers working with large data sets, as well.

企业间互供石脑油价格研究

企业间互供石脑油受计划经济、相关产品价格、石脑油质量标准及供货时间的影响，供需双方存在许多矛盾，关键在于石脑油价格。根据定价原则确定企业间互供石脑油的价格。尽快制定石脑油质量标准，调节７０＾＃汽油消费税，使石脑油与７０＾＃汽油价格差别趋于合理化，才能真正发挥集团优势。     

对西方财政职能理论的反思

西方财政三职能理论只是界定了财政的职责而没有说明财政的功能,把三项职能并列还容易引起逻辑混乱.完善三职能理论应首先寻找财政职责的功能基础,然后确定财政功能在市场经济条件下的职责体现.市场经济条件下财政的职能可以界定为是满足公共需要、提供公共产品,该职能可以从三个层次展开.

Estimating the Impacts of Outlet Rationalization on Retail Prices,Industry Concentration,and Sales: Empirical Evidence from Canadian Gasoline Markets

The retail gasoline industry in both Canada and the United States experienced a significant rationalization of outlets from the late 1970s through the 1990s. We estimate the impacts of reduced outlet density by exploiting the 27% decline in retail gasoline outlets across 10 Canadian cities between 1991 and 1997. Ordinary least squares and instrumental variables estimates suggest that rationalization resulted in a significant increase in retail prices, market concentration, and average outlet sales. The decline in retail outlets led to a 9% increase in retail prices, a rise in market concentration between 16% and 22%, and a 22% increase in average outlet sales.

关于构建纳税服务评价体系的几点思考

服务兴税,建立"服务型"和谐税务是当今税务工作的发展趋势。纳税服务工作的重要性逐步突显出来,纳税服务评价已成为提高税务机关管理服务水平和工作效率的重要手段。但目前,税务机关内部对纳税服务评价体系的建设和科学运用还不够完善,专门的内部考核制度和机构还不够健全。本文通过调查研究,结合税务部门的工作实践,重点分析了建立纳税服务评价体系的必要性、如何构建纳税服务评价体系以及发展趋势等问题。     

The persistence of the small firm/January effect: Is it consistent with investors’ learning and arbitrage efforts?

Using improved methodology and an expanded research design, we examine whether the small firm/January effect (Keim, D. B. (1983). Size-related anomalies and stock return seasonality: further empirical evidence. Journal of Financial Economics 12:13–32), is declining over time due to market efficiency. First, we find that January returns are smaller after 1963–1979, but have simply reverted to levels that existed before that time. Second, we show that the January effect is not limited to mature markets but also appears in firms trading on the relatively new NASDAQ exchange in the 1970s. Third, trading volume for small firms in December and January is not different from other months, implying that traders are not actively arbitraging the anomaly. Together, our results suggest that this anomaly continues to defy rational explanation in an efficient market.     

Transfers, the terms of trade, and capital accumulation

Abstract .  In the context of a two-sector overlapping-generations model it is demonstrated that a steady-state transfer paradox may arise under commodity trade with stability and without distortions or bystanders. The existence of the paradox is due to the effect of the transfer on world capital accumulation, which is shown to always (i.e., for any ranking of factor intensities and savings rates) improve the donor's terms of trade. Transfers may also improve steady-state welfare for both donor and recipient and produce paradoxical welfare results along the transition path.
