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.     

Price Rigidity and the Selection of the Exchange Rate Regime

We evaluate and qualify Friedman's, 1953, “case for flexible exchange rates” in the presence of sticky prices in a two country model. We find that a flexible regime performs indeed better when the degree of nominal price rigidity is high while a bilateral peg does better when prices are fairly flexible. This result obtains independent of whether monetary policy is activistic or not and is mostly due to the negative relationship between employment and productivity shocks when prices are relatively sluggish (Gali, 1999). A unilateral peg tends to produce the lowest level of world welfare but it sometimes represents the best monetary arrangement for the pegger. JEL Classification Numbers: E32, E52, F33, F42     

Pure Altruism,Consumer Behavior and Choice Modeling*

An important assumption underlying non‐market valuation is that it is not the environment but the human preference that is valued. This paper attempts to test whether individual consumer behavior is influenced by a purely altruistic motive, examining the attitude of hikers towards the hypothetical removal of the Muju ski resort from the Mount Togyu National Park in South Korea. Data were collected from samples of hikers and skiers who visited the national park. The respondents were forced to consider trade‐offs between the recovery of the lost environmental assets in the Muju ski resort area, skiers’ additional travel time, and willingness‐to‐pay amounts for the hypothetical environmental improvement. It was found that hikers did not take into account skiers’ disutility represented by additional travel time.     

论资产评估与会计的关系

资产评估与会计是既有区别又有联系的专业服务活动,本文通过讨论两者之间的关系,使我们明确会计提供以事实判断为主要内容的服务,资产评估提供以价值判断为主要内容的服务,它们都是现代市场经济赖以正常运行的基础服务行业。使我们更深刻地认识资产评估,更好地利用会计信息为评估服务,从而提高资产评估质量。     

高管连锁网络与股价同步性

本文以2009—2018年中国A股上市公司为研究样本,考察了高管连锁网络对公司股价同步性的影响。研究发现：高管连锁网络会提高公司的股价同步性,处于高管连锁网络越中心位置的上市公司,其股价同步性越高;从趋同性和信息透明度两个方面进一步分析高管连锁网络对股价同步性的作用机制,发现高管连锁网络并非通过降低公司透明度这一途径对股价同步性产生影响,而是因为连锁高管加强了上市公司间的行为学习、信息和资源的共享,促使公司间基础特征趋同,进而提高了公司的股价同步性;根据联结类型的不同将高管连锁网络划分为董事网络、监事网络和高管网络,实证结果表明高管网络对股价同步性的提升效应最大,董事网络次之,监事网络对股价同步性无显著影响;区分产权性质和法治环境后发现,在国有企业和所处法治环境较差的企业中,高管连锁网络提高股价同步性的效应更显著。研究结论为提升资本市场信息效率提供了理论支撑。     

Debt rescheduling and the choice between bonds and loans for LDCs' foreign debt

This paper examines less developed country (LDC) borrowers' choice of financing methods. I devleop and test the hypothesis that ex-ante consideration of rescheduling affects LDC borrowers' choice between bonds and commercial loans. Banks can monitor and distinguish between permanent and temporary shocks, while bondholders cannot. Therefore, debt rescheduling based on the nature of economic shocks is feasible with loan financing. Our empirical findings indicate the debt rescheduling is considered exante in LDC lending. In addition, default risk and contract size affect the choice of financing instruments.     

西部大开发对西部地区碳排放演变的影响

西部大开发后西部地区经济增长加快、人民生活水平提高,但产业结构、技术水平以及生态环境质量却并未表现出同等程度的改善或提升。采用30个样本省份1995—2011年的面板数据,运用双重差分法进行分析,结果发现：西部大开发在促进西部地区经济增长以及地区经济趋同的同时,也使得西部地区的碳排放（尤其是人均碳排放）与其他地区相比增长更快,与此同时,西部地区与碳排放相关的因素和条件（如产业结构、技术水平、市场化程度等）未得到显著改善。在既有的资源禀赋、发展阶段、产业结构以及经济发展方式下,西部大开发初期着力于固定资产投资和资源、能源开发,忽视教育事业、市场化改革、技术创新等软环境建设,导致西部地区在经济增长的同时碳排放相对增加。因此,在今后的西部大开发规划中,应当着力于转变经济发展方式,加强软环境建设,重视人力资本积累和技术创新,提升市场化水平,才能在发展地区经济的同时实现节能减排。     

欧美农产品价格支持政策的演变与启示

欧美农产品最低价格和目标价格在农产品市场供求关系、进出口政策和政府财政能力等约束之下,长期密切配合,共同促进了欧美农产品产量和农民收入的稳定增长。保护性收购方式下的最低价格干扰了市场价格的形成,非保护性收购方式下的最低价格对市场价格的形成没有影响,目标价格有效维护了供求关系决定价格的市场机制。最低价格和目标价格的使用与农产品供求状况没有必然联系,而最低价格的执行方式由农业资源禀赋和农产品供求关系决定。我国农产品的最低收购价抬高了市场价格,但其“拖市”功能有利于稳定农产品生产,而目标价格的反周期功能可稳定农民收入。因此,为保障国家粮食安全,我国不能以农产品目标价格取代最低价格,而应分品种施策不同的农产品价格支持政策。     

从马克思主义经济学看庇古分析与科斯分析之异同及其政策启示

针对外部性市场失效引发的生态环境问题,文章从讨论庇古分析与科斯分析的本质着手,运用马克思主义经济学关于个别生产与社会生产之关系的观点,引入价值体系与价格体系的数学规划模型,通过模型分析,从产权过程的角度,讨论庇古分析与科斯分析之并同和不完备性,从制度工具论的角度,归纳了两大分析的政策启示。
