Why is Inflation in China a Monetary Phenomenon？

This paper proposes that inflation in China during the post‐reform era (1978 onwards) is always a monetary phenomenon. We construct a multivariate dynamic model based on Friedman's quantity theory of money and use the standard Granger causality test to show that money growth contains significant predictive power for inflation during the underlying period. The finding is robust to alternative measures of monetary aggregates and both closed and open economy frameworks. The baseline finding of the paper indicates that quantitative tools remain the most important policy instruments for China to manage its inflation effectively.

Analysis of Investment Returns by Computer

This paper concerns itself with providing the means by which a decision-maker may choose among competing projects and arrive at the optimal allocation of the firm's scarce dollar resources. The problem is handled in the mathematical programming framework. The model holds with or without the assumption of capital rationing and permits the incorporation of the effects of growth and of alternative financial mixes on the cost of capital for the firm. When iterated, the model equates marginal revenue to marginal cost, thus yielding the optimal investment level for the firm. Several investment alternatives not considered in the existing literature on the subject are examined, and some novel interpretations of the constraints and results are offered.     

评估机构企业文化建设之我见

随着全球经济的快速发展，企业间的竞争越来越表现为文化的竞争。资产评估机构作为经济鉴证类中介机构，是企业的一分子，在市场竞争中塑造具有评估行业特色的企业文化显得至关重要。笔者从塑造以人为本的“家”文化、塑造“诚信文化”、打造“创新文化”三方面阐述了自己的观点，希望与广大评估人共同探讨、交流。     

聚醚淬火介质的应用研究

利用硬度评定法对聚醚淬火介质的成分进行了优选，结果表明：４５钢试样在浓度为１５％的聚醚水溶液淬火介质中淬火，不但表面硬度高，而且硬度梯度平缓。使用该淬火介质对４５钢轴承套圈淬火，在获得高硬度的同时，显著减小了淬火变形。     

Inflation persistence,inflation expectations,and monetary policy in China

This paper constructs a quarterly series of GDP deflator inflation for China from 1979 to 2009 and tests for a structural break with an unknown change point in the dynamic inflation process. Empirical results suggest a significant structural change in inflation persistence. Employing a counterfactual simulation method, we show that the structural change is primarily attributed to better conduct of monetary policy and the resultant better anchored inflation expectations. This finding implies that the quiescence of inflation in China over the past decade could well be followed by a return to a high inflation era in the absence of a determined effort by the monetary authorities in managing inflation expectations. Therefore, the use of a preemptive monetary policy to anchor inflationary expectations and to keep inflation moderate is warranted in China.     

Price‐matching policy with imperfect information

The model of price‐matching policy emphasizes on the importance of information imperfection. The demand is derived based on the assumptions that consumers have different reservation prices and different preferences over location. When a firm undercuts its competitor's price, it changes the demand structure of the market. The result shows that price‐matching policies are anticompetitive, but they do not facilitate monopoly price. Copyright © 2005 John Wiley & Sons, Ltd.
