双寡头竞争下的反倾销与补贴政策比较

与现有相关研究只注重Cournot模型不同,文章在Bertrand模型中,就反倾销税和生产补贴对进口国产量、进口量、消费量及社会福利等方面影响进行比较,试图理解进口国政府使用反倾销为代表的进口保护手段的动因。分析表明,在进口产品和本国产品差别不大的情况下,如果进口产品对本国产品具有明显的成本（即价格）优势,进口国政府从本国社会福利出发,会倾向使用反倾销税为代表的进口保护政策。根据结论,针对中国遭遇反倾销的现实,提出了调整出口目标和理念、调整和优化出口产品结构、调整中国出口产品的竞争策略等对策措施。     

Water pricing reform analysis: alternative scenarios

This paper compares alternative transition paths to efficient water pricing. The analysis is based on representative agent model, where two sources of water supply exist: exhaustible groundwater stock and a renewable substitute. Two alternative water pricing reforms are considered: gradual tariff increase and multipart pricing with first block sold at the initial pre-reform tariff and additional water sold at higher prices (block pricing reform). Under block pricing reform, the amount of water offered at low price gradually diminishes. The results of comparative analysis prove that under the same reform time horizon block pricing is preferred to the gradual tariff increase.     

Price competition between green and non green products under corporate social responsible firm

This article deals with a newsvendor inventory model in light of green product marketing of corporate social responsible firms. In this model, comparison between green and non green marketing is analyzed including subsidy and tax implementation by Government where the Government offers higher subsidy and lower tax to the green producer unlike the lower subsidy and higher tax to the non green producer. There is also price contest between green and non green producer as the demands of the products are dependent on sales price, carbon emission and corporate social responsibility index. Assuming the cost and profit parameters, an expected profit function of the systems is formulated and maximized analytically. Finally, numerical examples are illustrated to justify the proposed model.     

NO‐ARBITRAGE PRICING UNDER SYSTEMIC RISK: ACCOUNTING FOR CROSS‐OWNERSHIP

We generalize Merton’s asset valuation approach to systems of multiple financial firms where cross‐ownership of equities and liabilities is present. The liabilities, which may include debts and derivatives, can be of differing seniority. We derive equations for the prices of equities and recovery claims under no‐arbitrage. An existence result and a uniqueness result are proven. Examples and an algorithm for the simultaneous calculation of all no‐arbitrage prices are provided. A result on capital structure irrelevance for groups of firms regarding externally held claims is discussed, as well as financial leverage and systemic risk caused by cross‐ownership.     

Quantity price discrimination in the air transport industry: The easyJet case

This paper extends the literature on low-cost carriers' pricing strategies by investigating the presence of quantity price discrimination implemented through a two-part tariff in offered fares. By analysing Internet fares for all easyJet flights departing from the Amsterdam Schiphol airport between March and April 2015, we search for price differentials based on the number of seats booked by a single consumer. We find that the lowest average unit price is associated with a single consumer reserving 5 seats. On average, the per-seat discount for a single consumer reserving 5 seats is €9.48, which is 14% of the single-seat fare. Additionally, a multivariate analysis shows that quantity discounts are greater for flights with a larger fraction of available seats at the time of booking, the seats are booked longer in advance, and the destination's gross domestic product per capita is greater. Conversely, quantity discounts are lower for longer routes, larger destination airports, and routes for which easyJet's market share is higher.     

X射线测量InGaN多量子阱的厚度组分及应变

高分辨率X射线衍射具有不损伤样品,无污染、高精度等优点,能够得到有关晶体的完整信息,是研究薄膜性质的重要手段之一。本文采用高分辨X射线衍射得到InGaN/GaN样品的ω/2θ扫描图和倒易空间图,研究InGaN/GaN样品的应变和组分、InGaN/GaN多量子阱的平均组分级厚度周期。从倒易空间图像得出的晶格常数与由002面和105面摇摆曲线所计算出的晶格常数相比较,垂直晶格常数符合得很好,而水平方向的晶格常数则有较大的差别,可以认为从倒易空间图像中得出的晶格常数更为准确。     

碳关税的违法性及其应对

2009年美国众议院通过的《美国清洁能源与安全法案》规定,美国有权对包括中国在内的不实施碳减排限额国家进口产品征收碳关税。该法案有关碳关税的规定违反了《联合国气候变化框架公约》、《京都议定书》及WTO所确立的相关原则,也不符合WTO的相关条款。对此,我国必须在充分利用WTO现有法律机制的基础上,制定符合国情的碳税制度并积极参与国际规则的制定。     

新金融危机期间的贸易保护：国外研究综述

在全球经济一体化程度不断加深的背景下,始发于美国的金融危机迅速蔓延至全球。在这次危机期间,各国贸易保护措施的使用显著增加。由于经济、政治和法律背景发生了深刻变化,同时各国政府吸取了历史教训,当前的贸易保护主义与以前相比呈现出一些新特点,虽然其并未对当前世界经济和国际贸易产生太大的影响,但其潜在危害性也不可忽视。尤其是中国成为了各国贸易保护措施最频繁的目标指向,我们应深入研究新形势下贸易保护主义的特点与趋势及其对目标国的影响,寻求积极的应对策略。     

贸易壁垒与碳关税政策

国际贸易是在自由贸易与贸易壁垒长期斗争中发展起来的,美国等西方国家为了自身利益,抛开长期帝3定和遵守的自由贸易游戏规则,推出碳关税政策,利用全球对气候的关注抢占道德制高点,以此保护滞缓的经济。利益从来就是人类行动的指南,深度分析碳关税政策,从而制定出应对新贸易壁垒的良策是我们的利益所在。     

我国关税政策效应作用于经济增长路径的研究

理论研究表明,关税政策效应作用于经济增长的路径有可能是通过国际贸易和技术进步实现的。本文采用1978—2009年我国经济相关数据,建立VEC模型进行实证研究,结果表明,我国经济增长与关税政策存在协整关系,关税政策效应作用于经济增长的路径长期依赖于国际贸易,而短期依赖于国际贸易和技术进步。
