Choice of Portfolios and Fee under Principal -Agent Framework with Uncertain Exit - Time

In the real world, an investor is usually not sure about when he or she will exit investment. She can only make estimation prior. With the growth of the scale of open - end funds which can be subscribed and redeemed at any time. Investors began to pay more attention on problems such as whether the fee is reasonable, the payment can encourage the agent or not. Others would consider if the portfolio that the agent chooses is the best one. This paper considers the principal - agent problem with uncertain exit - time under two cases： the action of the agent is observable and unobservable. We derive close - form expressions of the optimal portfolio and the best fee. Finally an empirical analysis is given based on the data of some open - end funds in China.

Geodemographic and socioeconomic characterization of the retail attraction of leading hypermarket chains in Spain

This paper aims at examining the impact on demand of the competitive positioning strategies developed by the leading hypermarket chains in Spain. Specifically, the purpose is to carry out a geodemographic and socieconomic characterization of the potential consumers of each chain. As retail attraction has traditionally been divided into three components, distance, mass and image, a gravitational model is proposed which distinguishes them and facilitates the evaluation of existing differences across any a priori segmentation base. The empirical test identifies significant geodemographic differences in the retail attraction of hypermarket chains. Chains seem to target the whole market by developing an image balanced against the advantages and disadvantages derived from the spatial coverage strategy. Social class is not as good an indicator of hypermarket choice as expected, although some interesting patterns have been detected.

Towards an Integrated Statistical System at Statistics Netherlands*

Changes in circumstances put pressure on Statistics Netherlands (SN) to redesign the way its statistics are produced. Key developments are: the changing needs of data‐users, growing competition, pressure to reduce the survey burden on enterprises, emerging new technologies and methodologies and, first and foremost, the need for more efficiency because of budget cuts. This paper describes how SN, and especially its business statistics, can adapt to these new circumstances. We envisage an optimum situation as one with a single standardised production line for all statistics and a central data repository at its core. This single production line is supported by generic and standardised tools, metadata and workflow management. However, it is clear that such an optimum situation cannot be realised in just a few years. It should be seen as the point on the horizon. Therefore, we also describe the first transformation steps from the product‐based stovepipe‐oriented statistical process of the past to a more integrated process of the future. A similar modernisation process exists in the area of social statistics. In the near future both systems of business and social statistics are expected to connect at pivotal points and eventually converge on one overall business architecture for SN. Discussions about such an overall business architecture for SN have already been started and the first core projects have been set up.

对中国信用卡消费群体特征的多元统计分析

本文在北京地区调查问卷的基础上设计了一套信用卡评价量表,通过多元统计中的因子分析、方差分析、卡方检验等手段分析信用卡评价变量与人口统计变量的相互关系,从量化的角度得出中国信用卡市场的基本现状和特点:信用卡各项服务的水平有很大的提升空间,开发潜力很大;信用卡的年费普遍过高;年轻群体相比于其他年龄群体对于信用卡的接受度、认同度、透支程度、及时还款程度都是最高的;信用卡的功能有待进一步开发;新功能的宣传所达到的效果较小;营销的细分市场应该主要通过透支额度和服务程度等来划分.最后文章还提出了相应的政策建议.     

Introduction: Globalization and the Workplace in Pacific Asia

Hong Kong's economic successes are evident. As ever, the interpretation of this phenomenon at the level of politics, culture, human capital and business organization is less obvious, though a familiar list of the ‘usual suspects’ of ‘explanations’ has emerged. Hong Kong now faces new and renewed challenges which are linked to shifts in the industrial structure, emerging market demands and the interconnected upgrading of both production and human resources, in addition to the implications of reunification. Key themes of national competitiveness, deindustrialization and the upgrading of production facilities and human resources are all shown to be important, but also multi-layered and hazy concepts.
