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。     

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。     

货币政策对股票价格行为的影响实证分析

文章以影响股票价格的理论为基础,采用现代计量技术,采用2005年1月至2007年6月的月度时间序列数据,研究了汇率、存款准备金率以及利率、货币供应量等宏观经济因素对股票价格的影响。从2005年6月以来我国A股市场股票价格的持续上涨,其主要原因是经济的高速增长、人民币升值以及充足的货币供应量;而加息与提高存款准备金率对股票价格变化的影响有限。     

Quote inefficiency in options markets

In an arbitrage-free economy with non-zero bid-ask spreads the existence of payoffs whose price is lower than the price of a dominated payoff cannot be discarded in general. However, when the former price corresponds to trivial portfolios which involve buying or selling one unit of the basis assets, its presence, although not an arbitrage, is a severe market anomaly which we refer to as an inefficient quote. In an empirical study, we report evidence that indicates that in options markets both the frequency and the magnitude of these anomalies are substantial and we document puzzling patterns in their behavior.     

我国煤炭资源税从价计征的局限性研究——基于征税效果和效率的预评价

从征税效果和效率的视角,对资源税从价征收进行了预评价。评价结果表明,从价计征改革存在2大局限性,一方面无法达到"地方政府摆脱资源大省、财政小省困境"和"提高回采率、保护煤炭资源"等预期效果;另一方面,会造成征税的双重超额负担,导致征税低效率。在此基础上,建议应从整体而非局部推动煤炭资源税费改革,系统地进行煤炭资源税收体系再设计。
