Does competitive pricing cause market breakdown under extreme adverse selection?

We study market breakdown in a finance context under extreme adverse selection with and without competitive pricing. Adverse selection is extreme if for any price there are informed agent types with whom uninformed agents prefer not to trade. Market breakdown occurs when no trade is the only equilibrium outcome. We present a necessary and sufficient condition for market breakdown. If the condition holds, then trade is not viable. If the condition fails, then trade can occur under competitive pricing. There are environments in which the condition holds and others in which it fails.     

星级酒店客房定价策略分析

客房是酒店收入的主要来源,而对于经济型酒店来说就更加重要了。酒店经济效益的好坏关键就取决于是否能够制定出合理的客房价格。在酒店经营中,也会有很多的因素制约着客房价格的制定,通过对客房价格制定方面的分析,来探讨增加酒店营业收入和利润的定价策略。     

转让定价、公平性感知和子公司业绩

基于组织公平理论的研究成果和转让定价现状,首先用组织公平理论的三维模式从分配公平、程序公平和互动公平三个维度分析了影响转让定价公平性感知的因素,如利润分配、发言权、信任、尊重等,然后探讨了转让定价公平性感知对子公司经理的行为和态度及子公司业绩的影响:公平性感知通过影响子公司经理的态度,如信任及满意度等影响子公司的业绩。最后提出了提升转让定价公平性感知的策略,如建立双向交流的机制、协商式的市场定价方法等,这些对集团转让定价政策机制的制定以及达成其战略目标有一定的指导意义。     

CONVERTIBLE BOND PRICING MODELS

Convertible bonds are an important segment of the corporate bond market, with worldwide outstandings approaching US$235 billion. Simple pricing models value a convertible bond as being equivalent to a straight bond with an embedded option that enables the bond holder to convert to a specific amount of common stock. The straight bond is subject to both interest rate and credit risk, whereas the option to convert is dependent on the underlying stock price, which exposes the convertible bond holder to equity risk. The complexity of these features means that convertible bonds tend to be treated casually in major derivatives and corporate finance textbooks. This paper presents a survey of the theoretical and empirical aspects of convertible bond pricing. The limitations of these studies are highlighted to identify those areas of research that may improve the valuation process and facilitate the application of these securities for corporate financing.     

基于中等收入人群的阶梯电价改革对其经济利益影响的实证分析

实施居民阶梯电价制度的根本目的是为了促进节能减排,电价改革会极大地影响居民的生活成本。本文以四川省仁寿县视高镇为研究对象,从中等收入人群的角度出发,实地调查收集大量数据,通过建立数学模型,定量分析了阶梯电价改革对其经济利益的影响,并提出了相应的对策建议,以期能为相关部门制定改革方案提供参考。     

基于Bertrand模型的区域港口双寡头定价策略

基于Bertrand模型的数理分析研究了区域港口双寡头的最优定价策略,指出双寡头在定价策略上的合作有利于提高双方的价格和利润。当寡头存在强弱之分时,强势的寡头定价高一些,弱势的寡头定价低一些,在双方价格的纳什均衡点,双方可以获得最大化的均衡利润。并以上海港与宁波-舟山港为案例进行了实证分析。     

普通高校收费定价模型研究

高等教育收费问题已经成为社会关注的热点问题。本文综合考虑了政府、家庭、学校及社会对高等教育成本的分担能力,制定了一个合理的承担比率,并以此为基础建立了学费定价模型,最后利用相关数据对模型进行了实证分析。     

开放条件下国际资产定价模型的解析与检验

随着经济全球化的不断深入，国际资本市场的一体化程度也在不断加强，敌对国际资产定价问题的探讨显得颇为重要。尤其对开放条件下的国际资产定价理论与实证研究进行系统的梳理与分类，并对该领域现有研究中存在的问题提出未来研究的方向，更有学术价值。     

Carbon pricing and terms of trade effects for China and India: A general equilibrium analysis

Using country-specific dynamic computable general equilibrium (CGE) models, this paper estimates carbon prices in China and India, and compares the effects of carbon pricing policies under terms of trade effects. Estimated carbon prices are higher in China due to differences in emission intensity and in the rate of deployment of new technologies in the models. Differences in carbon prices open up the possibility of carbon trading between the two countries to achieve mitigation objectives. Further, under assumptions about different exchange rate regimes and international fossil fuel prices, the effects of carbon pricing policies on the two economies are mostly similar in terms of direction but, expectedly, different in terms of magnitude. Terms of trade effects could exacerbate carbon pricing effects to a greater degree in China as the country is significantly more dependent than India on external trade and investment. Policymakers should factor in terms of trade effects while designing or evaluating carbon pricing policies in the two countries.
