Comparing the impacts of Internet technology and national culture on online usage and purchase from a four-country perspective

The Internet has successfully generated an ever-expanding cohort of users for all its major concomitant activities, including information gathering, communications and transactions. So far no attempt has been made to validate whether such a success is so deep as to transcend national cultures. Nor any work has been conducted to compare the internationalisation¹ performances between online usage activities. The current study addresses these two research gaps from the perspective of four countries, i.e. Britain, Germany, Japan and Taiwan. Results show that although the technological forces have been quite successful in internationalising overall online usage activities, they succumb to the cultural forces as far as only the transactions activity, or more colloquially online purchase, is concerned. This indicates the relative difficulty in internationalising online purchase vis-à-vis other online usage activities. Further research on locating a series of step functions or kick-off time points regarding the development of online purchase is suggested.

Optimal Contracts for Central Bankers: Inflation versus Money Supply and Exchange Rate Targets

Some recent papers have shown how a simple contract can eliminate the inflationary bias of discretionary monetary policy. This paper shows that if the central banker is risk averse, a contract in terms of money is superior to one in terms of inflation. The paper also shows that, if the central banker cares about his reappointment, an exchange rate target might always leads to the implementation of the optimal policy.     

Probability theory in fuzzy sample spaces

This paper tries to develop a neat and comprehensive probability theory for sample spaces where the events are fuzzy subsets of The investigations are focussed on the discussion how to equip those sample spaces with suitable -algebras and metrics. In the end we can point out a unified concept of random elements in the sample spaces under consideration which is linked with compatible metrics to express random errors. The result is supported by presenting a strong law of large numbers, a central limit theorem and a Glivenko-Cantelli theorem for these kinds of random elements, formulated simultaneously w.r.t. the selected metrics. As a by-product the line of reasoning, which is followed within the paper, enables us to generalize as well as to bring together already known results and concepts from literature.Acknowledgement.

消费者与组织购买行为的比较研究

消费者购买行为是消费者为满足个人或家庭生活需要而发生的购买商品的决策或行动，组织购买行为是组织与组织之间的营销活动。组织购买与消费者购买有着较大的差异，因规模远比后者大而对市场经济的作用巨大，在市场营销理论中也占看重要的地位。对消费者与组织购买行为进行比较研究，对组织购买决策模型加以对比分析，有助于更好地理解组织购买活动与购买决策过程。     

我国央行控制货币供给能力的分析

本文首先从货币供给过程中的基础货币和货币乘数这两个环节入手,从理论上分析了我国央行对货币供给的控制能力.同时我国正处于社会主义市场经济的发展和转轨阶段,市场经济体制还很不完善,这些特殊国情使得我国的货币供给量更加难以控制.而且在当今金融创新、金融放松管制和全球金融市场一体化的背景之下,各个层次的货币供应量之间的界限更加不易确定,基础货币的扩张系数也失去了以往的稳定性,这又进一步强化了我国货币供给的内生性.通过对上述复杂因素的综合分析,探讨了我国央行对货币供给不可控性的深层次原因.

出口退税分税制:未竟的改革

2004年开始实施的旨在减轻中央政府退税负担的出口退税分税制，在执行过程中会遇到诸如地方政府财政困难而无力承担退税义务、难以有效抑制地方政府的出口冲动和跨地区退税难以协调等问题。为保证出口退税分税制的顺利实施，就要平衡地方政府的事权与财权，建立健全政府信用体系，坚持增值税征收权利与退还义务相平衡的原则，同时还要保持政策的灵活性。
