论本币升值对国内物价的影响路径

本币升值可通过实体经济、虚拟经济以及货币政策三个途径影响一国的国内价格;本币升值通过国内物价影响经济稳定存在一个正反馈机制;从短期来看,人民币升值不仅不能抑制国内物价上涨,还可能推动国内物价的上涨。     

中国郑州棉花期货市场的国际定价功能研究

本文借助计量经济学的分析方法,对郑州商品交易所、纽约期货交易所期棉价格与国内棉花现货价格这三者的关系进行了研究,并测算了郑州商品交易所与纽约期货交易所在价格发现中的贡献份额。研究结果表明,三者之间存在协整关系,纽约期货市场在国际棉花定价体系中占有主导地位,而导致郑州棉花期货市场国际定价功能弱化的原因则是国内棉花期货市场与现货市场缺乏有机联系。     

Advertising,Price and Quality in Self–regulating Professions: A Survey

This paper surveys the theoretical and empirical literature on the relationship between advertising, fees and quality in the self–regulating professions. Much of the literature is derived from the perspective of advertising as an information–enhancing device, helping to reduce the information asymmetry between professional and client. This is consistent with the majority of the empirical studies which suggest that advertising tends to have a downward effect on professional fees, with little if any adverse effect on quality. There are, however, important issues of method and measurement which may lessen the force of this conclusion     

Learning-by-doing and input demand of a rate-of-return regulated firm

The significance of learning by doing to input demand of a cost-minimizing rate-of-return-regulated firm is examined. Using a panel data, the results indicate that the firm's cost and input demand decisions are both influenced by learning-by-doing. The firm's cost and the rate-base (capital) input requirements decline as learning-by-doing measured by cumulative production expands. However, LBD may have different effects on the non-rate-base inputs (labor and fuel) considered in this study. While LBD ambiguously reduces fuel usage, it moderately increases labor employment. In addition to changing input intensity, LBD also influences returns to scale and elasticity of substitution.     

The Analysis and Improvement on the Lowest Price Method

The book of Modem Consulting Method and Practice is the appointed teaching material for registered consulting engineer qualification examination （investment） of China. Its Lowest Price method in evaluating mutually exclusive project has some problems, which contradict the delta IRR and NPV methods. We improve the method and recommend Good-Bad Boundary Price Method to solve problem of this type.     

Some Evidence on the Adjustment of Producer Prices*

We document producer price adjustment using a low‐inflation micro price dataset. On average 24% of prices adjust each month, with an average increase/decrease of 6%. Producer prices adjust more frequently than consumer prices, but their size of adjustment is typically smaller. Sectoral heterogeneity in the frequency of price adjustment is strongly related to heterogeneity in the cost structure. Fluctuations in aggregate producer price inflation occur to a large extent through variation in the relative share of upward and downward price adjustment.     

公司价值评估中管理者柔性的价值评估研究

现在公司价值评估方法往往没有考虑到对管理柔性价值定价问题。由于管理柔性价值定价是一种类似期权的定价，因此本运用Black—Scholes期权定价模型和买权卖权平价关系，定价管理柔性价值，来完善公司价值评估中的折现现金流量模型。     

边疆民族地区经济增长与就业关系比较研究

通过建立GDP就业模型揭示经济增长与就业的内在关系。要增加就业降低失业率，必须保持快速和稳定的经济增长和提高GDP就业弹性。比较分析边疆少数民族地区和东部发达地区的GDP就业弹性，发现由于东部发达地区经济更依赖于资本和技术进步，其GDP就业弹性、GDP对就业的“指数效应”比边疆少数民族地区的小。同时随着边疆少数民族地区经济的资本有机构成逐渐提高和进一步的资本深化，GDP就业弹性也在逐渐下降。东部发达地区GDP对就业的“乘数效应”比边疆民族地区的大，说明了东部发达地区依然是吸收就业和农村剩余劳动力的主要地区，并提出增加就业的对策建议。     

Winner-take-all price competition

Summary. We analyze an oligopoly model of homogeneous product price competition that allows for discontinuities in demand and/or costs. Conditions under which only zero profit equilibrium outcomes obtain in such settings are provided. We then illustrate through a series of examples that the conditions provided are “tight” in the sense that their relaxation leads to positive profit outcomes.

货币政策的粘性均衡汇率效应模型及人民币汇率定价的弹性分析

本文以开放的宏观经济为框架、以厂商利润最大化为微观经济基础、以严格的数学推导为逻辑纽带、以粘性价格为理论依据、以购买力平价的微分冲击形式为理论基础，提出并构建了两国货币政策的粘性均衡汇率效应模型。应用模型，本文对1992～2002年的人民币粘性均衡汇率进行了定价，并对2003年的定价进行了预测。以定价汇率及其预测为标准，对1992～2003年的人民币汇率偏离与经常性项目的关系，进行了弹性分析。根据模型与实证分析，获得了一些重要结论。
