国际商务交易中的预付卡制度研究——基于沃尔夫斯堡规则视角

在美债危机与欧洲危机的背景下，预付卡作为刺激金融服务业发展的手段之一，在国内外快速发展。伴随预付卡在我国的广泛使用，其风险问题也日趋严峻。研究分析我国预付卡制度对推动金融机构反洗钱监管、遏制反洗钱犯罪具有重要的现实意义。本文在阐述我国预付卡现状的基础上，初步分析了我国预付卡行业的相关法律、法规并不健全等问题。通过借鉴沃尔夫斯堡组织中预付卡发展和管理的先进经验，提出从立法、交易监控等方面完善我国预付卡制度的建议。     

对会员卡法律关系性质的探究

会员卡源于西方会员制,在高档场所实行,体现身份和地位。根据不同标准,中国会员卡有准入式与非准入式、预付式与非预付式之分类。会员卡与信用卡、公交IC卡不能等同。准入式与预付式会员卡法律关系是继续性合同。准入式下的持卡人既是会员也是成员,其身份具有双重性;而非预付式会员卡法律关系构成两个相互关联且具有一定独立性的联立合同。

我国预付式代币卡规制法律制度之反思

法律是一个因时而化的问题,其好与坏、精致与拙劣在于能否适应社会发展的内在要求。虽然预付卡存在一些内生的缺陷,但是这并不能成为法律对其永久断然"说不"的理由,因为在本质上,预付卡是科技化时代下市场发展的必然产物。从市场需求、预付卡的特征、内在风险等角度来因势利导、趋利避害地规范预付卡的发展才是应有的法律思维。     

Forecasting client retention — A machine-learning approach

In the age of big data, companies store practically all data on any client transaction. Making use of this data is commonly done with machine-learning techniques so as to turn it into information that can be used to drive business decisions. Our interest lies in using data on prepaid unitary services in a business-to-business setting to forecast client retention: whether a particular client is at risk of being lost before they cease being clients. The purpose of such a forecast is to provide the company with an opportunity to reach out to such clients as an effort to ensure their retention.We work with monthly records of client transactions: each client is represented as a series of purchases and consumptions. We vary (1) the length of the time period used to make the forecast, (2) the length of a period of inactivity after which a client is assumed to be lost, and (3) how far in advance the forecast is made. Our experimental work finds that current machine-learning techniques able to adequately predict, well in advance, which clients will be lost. This knowledge permits a company to focus marketing efforts on such clients as early as three months in advance.     

Cost allocation of WCDMA and wholesale pricing for mVoIP and data services

This study estimates cost-based prices for wholesale voice and data services provided to 3G (WCDMA) MVNOs according to their distinct types. For estimation, 3G MVNOs are classified into different types, and the overall cost of WCDMA facilities are separated into voice and data components based on their subscriber rates, actual traffic rates, as well as efficiency consideration of traffic rates. The study then calculates cost-based wholesale prices of voice and data services for each of the 3G MVNO types. The result of this study shows that a cost-plus pricing scheme can help achieve the policy goals of the regulator, namely, lowering telecommunications tariffs and facilitating the introduction of new convergent-type services, far more effectively than the current retail-minus pricing scheme. The findings of this study may assist firms in developing business models based on 3G networks and telecom regulators in designing policies related to interconnection, mVoIP, prepaid calls, wholesale services, and network neutrality.     

宏观投资核算的类型及其改进——兼与微观投资的比较

本文简要分析了微观投资的类型,并从对象、主体等角度对宏观投资进行类型化分析,指出宏观投资核算存在的问题及其改进策略。以此为基础,本文比较了两类投资的差异,指出微观投资可以是存量,也可以是流量;宏观投资一般是流量,也可以用宏观投资存量表示存量。因此,只有微观流量对应宏观流量,微观存量对应宏观存量,才能实现两类投资的转换。
