监管防范BEPS 基层税务机关应该做什么

跨国企业利用税务筹划方案侵蚀税基或进行利润转移的行为十分普遍,对我国税收主权造成了很大的威胁,然而目前我国基层税务机关还不能很好地应对BEPS带来的挑战。本文介绍了BEPS的基本形式、对我国的影响及OECD防范BEPS的最新进展,并从基层税务机关的角度出发,提出了关于监管防范BEPS的工作建议。     

坚持"儿童优先",关注儿童健康

引言 儿童是祖国的未来,民族的希望.中国有三亿六千万儿童,占世界儿童总数的六分之一.关注儿童健康,保护儿童成长,是全社会共同的责任.正如温家宝总理所言,使每一个儿童都幸福地生活,受到良好的教育,健康地成长,是我们最为崇高的使命.

试析棉纺企业供应链采购成本

本文通过透视我国棉纺行业现状,在进一步分析棉纺企业供应链采购成本影响因素的基础上提出了控制供应链采购成本的几点可行性建议。     

一体化供应链组合战略的构建

随着供应链之间竞争的加剧,单一地采用精细思想和敏捷思想设计供应链已经不能满足客户的要求。只有合理地运用精细思想和敏捷思想的组合战略,才能使供应链能够同时达到满足终端顾客的产品可获性和有能力购买性的双重需求。同时,使用模块化设计能够降低供应链组合策略的复杂性,增强供应链的适用性和通用性,使供应链结构变得简单化。

HIGH‐ORDER SHORT‐TIME EXPANSIONS FOR ATM OPTION PRICES OF EXPONENTIAL LÉVY MODELS

The short‐time asymptotic behavior of option prices for a variety of models with jumps has received much attention in recent years. In this work, a novel second‐order approximation for at‐the‐money (ATM) option prices is derived for a large class of exponential Lévy models with or without Brownian component. The results hereafter shed new light on the connection between both the volatility of the continuous component and the jump parameters and the behavior of ATM option prices near expiration. In the presence of a Brownian component, the second‐order term, in time‐t, is of the form , with d₂ only depending on Y, the degree of jump activity, on σ, the volatility of the continuous component, and on an additional parameter controlling the intensity of the “small” jumps (regardless of their signs). This extends the well‐known result that the leading first‐order term is . In contrast, under a pure‐jump model, the dependence on Y and on the separate intensities of negative and positive small jumps are already reflected in the leading term, which is of the form . The second‐order term is shown to be of the form and, therefore, its order of decay turns out to be independent of Y. The asymptotic behavior of the corresponding Black–Scholes implied volatilities is also addressed. Our method of proof is based on an integral representation of the option price involving the tail probability of the log‐return process under the share measure and a suitable change of probability measure under which the pure‐jump component of the log‐return process becomes a Y‐stable process. Our approach is sufficiently general to cover a wide class of Lévy processes, which satisfy the latter property and whose Lévy density can be closely approximated by a stable density near the origin. Our numerical results show that the first‐order term typically exhibits rather poor performance and that the second‐order term can significantly improve the approximation's accuracy, particularly in the absence of a Brownian component.     

价格听证会的效率分析--以中国首次铁路客运价格听证会为例

一、引言 价格听证制度最早出现在美国,经过50多年的发展,该制度已经成熟.我国的价格听证制度体现于<价格法>第23条:"制定关系群众切身利益的公用事业价格、公益性服务价格、自然垄断经营①的商品价格等政府指导价及政府定价,应当建立听证会制度,由政府价格主管部门主持,征求消费者、经营者和有关方面的意见,论证其必要性、可行性."2001年出台的<政府价格决策听证暂行办法>规定了听证会的具体程序.

绿色贸易措施的政治博弈

随着贸易自由化和全球经济一体化,世界各国出于维护本国国际竞争比较优势战略目标和实现贸易与环境协调发展的客观需要,以可持续发展为口号,以保护环境和人类健康为目的或借口,以产品标准、环境标志、绿色包装、贸易制裁等为手段的绿色贸易措施正在成为国际社会特别是发达国家越来越频繁使用的新的国际贸易保护手段。形形色色的绿色贸易措施正在向系统化、制度化和国际化方向演进。本文通过对近期一些国外经济学家的相关文献回顾,对绿色贸易措施产生的政治博弈过程进行简单的综述,为我国参与新一轮的WTO谈判提供一些理论参考。
