基于利他行为下的闭环供应链决策研究

随着行为运营管理的发展,利他、公平、信任等行为得到广泛的关注。文章构建一个由供应商和零售商的闭环供应链,供应商负责旧产品回收再加工。将利他行为引入到供应链中,研究利他属性对供应链决策的影响。研究发现,在该模型的供应链中,供应商的利他属性,对于供应链的回收率、零售商的利润、供应商的效用、供应链的整体利润都是有益的。而零售商的利他行为,有利也有弊,带来的效益是局部的。然后通过数值分析对结论作出解释和说明。     

Product-market strategies in the minicomputer industry

The minicomputer industry has undergone rapid technological change over the last decade and is now characterized by high growth, the emergence of new markets, and intense competition. This article addresses the marketing strategies employed by large and small firms in the minicomputer industry and identifies trends and dimensions that are important for success in such a rapidly changing environment.     

Some order relations between selection and inclusion probabilities for PPSWOR sampling scheme

In this paper we study some order relations between the selection and the inclusion probabilities for PPSWOR Sampling Scheme. We also establish some interesting bounds on the inclusion probabilities in terms of the selection probabilities.     

Estimation problems for rectangular distributions (or the taxi problem revisited)

The problem of estimating the unknown upper bound on the basis of a sample of sizen from a uniform or rectangular distribution on [0, ] has considerable interest. This or the analogous discrete version is variously known as the Taxi-problem or the German bomb (or Tank) problem and has a long history. The emphasis here is on estimation of through the lengths of the observed gaps or spacings which seem natural for this problem.     

中国两缺口不缺情况下的外资引进:1994-2004——一个金融视角下的微观解释

本文在两缺口理论的分析框架下,分析了我国金融系统转化国内储蓄为投资的过程,发现由于金融系统对内资企业的融资支持效率低下和外汇市场的不完善,导致我国在企业层面上还存在一定程度的储蓄缺口和外汇缺口,还存在着引进外资的微观基础.从金融角度解释了我国大量引进外资与两缺口不缺的矛盾.     

A COMPARISON OF POUND STERLING-AUSTRALIAN DOLLAR PURCHASING POWER PARITIES FOR SELECTED POPULATION SUB-GROUPS IN AUSTRALIA AND THE UNITED KINGDOM1

This paper utilizes Household Expenditure Survey and Consumer Price Index data supplemented by private survey data in an attempt to compare the purchasing power parities of the pound sterling and the Australian dollar for a range of population sub-groups in the United Kingdom and Australia. In spite of the close political, economic, social and cultural ties that exist between these two countries, there have been no attempts to measure differences in living costs and real expenditures. Further, Australia has not been a party to the International Comparisons project of the Statistical Office of the United Nations. This study derives purchasing power parities which explicitly account for variations in expenditure patterns of different population sub-groups. For example, a household living in London intending to move to Sydney will find it useful to have a comparison of cost-of-living between households living in these two cities which takes into account explicitly the general expenditure patterns in these two cities. Due to the nature of the data, it was necessary to employ a new index number method derived by one of the authors.     

A forecasting model of the Kenyan economy

A demand-oriented macroeconometric model of the Kenyan economy is developed and estimated in line with the cointegration technique. The estimated structure of the model is used to perform policy simulation experiments to determine the sensitivity of key macroeconomic variables to changes in exchange rate, net government current expenditure and nominal interest rate. The results of policy simulation experiments reveal that the exchange rate and fiscal policies are relatively more effective than the monetary policy, i.e. changing the nominal interest rate, in influencing the level of economic activity. The results point to the possibility of devaluation improving the international trade balance.     

ECONOMIC ACCOUNTS FOR DEVELOPING COUNTRIES

This paper has three parts. The first part attempts to analyse the prevailing situation in developing countries. The second part presents a feasible accounting system for such countries, by and large within the framework of the SNA. The third part goes beyond this and tries to obtain a more concise matrix (covering, in concept, those given in the accounting system) furnishing minimal sets of variables and classifications which one has, in any case, to play within the context of policy issues of developing countries. All three authors are jointly responsible for the first part. Uma Datta Roy Choudhury has drafted the second part. The third part has been drafted by the other two authors.     

Comparisons of real output and productivity of Chinese and Indian manufacturing, 1980–2002

The principal objective of this paper is to compare the real output and labour productivity of Chinese and Indian manufacturing from 1980 to 2002. Using an industry-of-origin approach, purchasing power parities (PPPs) for the benchmark year 1985 are derived from the Chinese and Indian industrial censuses. In turn, the PPPs are used to convert Indian manufacturing GDP into Chinese yuan for direct comparisons. Secondary objectives are twofold: first, to set this direct comparison within the general context of the economic policy reform process followed in each country, and second, to compare and contrast the organisation and structure of both countries' manufacturing sectors. The analysis shows that since 1980, real value added and labour productivity growth for Chinese manufacturing has been well above Indian levels.     

国外纳税遵从研究动态

国外有关纳税遵从的研究主要从以下两条途径展开:一是起始于Allingham & Sandmo的A-S分析模型,运用预期效用理论来分析纳税人的纳税遵从决策;二是基于Tversky & Kahneman提出的期望理论分析风险选择偏好以及框架效应等对纳税人纳税遵从行为的影响,并解释预期效用理论下分析纳税人纳税遵从行为的一些困惑.本文借鉴国外纳税遵从的研究并结合我国实际情况,提出了完善我国的税务稽查与处罚制度、提高社会整体税收道德水平、增强财政公平度及优化税款预缴制度以提升我国的纳税遵从水平的建议.
