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。     

长期协议、价格指数和铁矿石定价研究

在长期协议市场和现货市场并存的条件下,当市场存在不确定性和信息不对称时,可以减小随机交易波动,这不仅有利于保持长期协议供给方的领先优势,还能有效降低市场的均衡价格。在我国进口铁矿石定价体系中,国外厂商铁矿石价格指数和中国铁矿石价格指数存在差异和共同点,因此,只有建立运行高效的铁矿石市场交易机制,我国才能获得国际铁矿石定价权。     

Beauty contest,bounded rationality,and sentiment pricing dynamics

We present a dynamic asset pricing model that incorporates investor sentiment, bounded rationality and higher-order expectations to study how these factors affect asset pricing equilibrium. In the model, we utilize a two-period trading market and investors make decisions based on the heterogeneous expectations principle and the “sparsity-based bounded rational” sentiment. We find that bounded rationality results in mispricing and reduces it in next period. Investor sentiment produces more significant effects than private signals, optimistic investor sentiment increases hedging demand, thus causing prices to soar. Higher-order investors are more rational and attentive to the strategies of other participants rather than private signals. This model also derives the dampening effect of higher-order expectations to price volatility and the heterogeneity expectation depicts inconsistent investor behavior in financial markets. In the model, investors' expectations about future price is distorted by their sentiment and bounded rationality, so they obtain a biased mean from the signal extraction.     

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.     

排污权有偿使用阶梯式定价研究——以化学需氧量排放为例

依据河南省2010年污染源普查数据,分析了不同行业化学需氧量排放的公平性问题,基于不同行业经济贡献与排污量之间的差异性的基础上,参考阶梯水价和电价的制定思路,提出了排污权阶梯式定价,并对其内涵与经济学特征进行了分析,最后,在恢复成本法定价的基础上制定了河南省化学需氧量有偿使用阶梯式价格。     

非线性定价的福利再分配效应研究——基于非对称双寡头市场的分析

较之"线性定价","非线性定价"在社会福利方面的优势被现有理论反复证明。在肯定"非线性定价"方式能够改进社会总福利的同时,指出并不是每一个市场主体的福利水平都能够通过"非线性定价"方式得到改进。通过建立模型、计算和比较分析,提出了在上述两种情况下,"非线性定价"可能会对特定的市场主体产生"福利剥夺",从而出现福利再分配效应。     

Pro-cyclical effect of sovereign rating changes on stock returns: a fact or factoid?

This article examines the effect of changes in sovereign credit ratings and their outlook on the stock market returns of European countries at different phases of business cycle. Using standard four-factor model, it records a significant average marginal effect of credit rating announcements on stock market returns. Both magnitude and significance of the effect vary with business cycle and across announcement types. However, we do not find evidence of pro-cyclical effect of sovereign rating and outlook changes on stock returns. Our results show that stock markets react more negatively to rating downgrades in recovery phases and more positively to rating upgrades in contractionary period. Both results are statistically significant and robust to various sensitivity tests.     

双边间接网络效应对平台产品扩散与定价的作用研究

本文在BASS扩散模型的基础上,引入双边间接网络效应的作用,建立平台产品的扩散模型。研究发现:双边间接网络效应产生潜在的市场规模扩张,其和市场单边自扩散共同作用,使得平台产品的扩散形态可能呈单峰或多峰形状。按双边扩散表现为相互制约还是相互促进,平台产品市场扩散可分为潜在市场规模扩张起飞前和潜在市场规模扩张起飞后两个阶段。平台运营者需要正确判断产品扩散所处的阶段,谨慎制定正确的定价策略。     

政府与企业在排污权定价中的演化稳定策略研究

本文从动态博弈的视角分析了政府与企业在排污权价格制定上的策略演化,获得了与现实世界较为拟合的演化稳定策略,对政府制定公平有效的排污权定价模式提供了可资借鉴的参考。     

基于Merton模型的存款保险定价研究

存款保险制度的核心是存款保险费率的厘定。本文以Merton存款保险定价的看跌期权模型为基础,引入监管宽容和未保险存款的利率两个参数,给出了商业银行存款保险定价公式。选择不同的银行对其保险费率进行估算,所得的保险费率之间有一定的差距,表明不同银行的存款保险费率是不同的,中国不适合单一费率,而适合风险费率。本文对我国正在酝酿出台的存款保险制度具有一定的指导意义。
