A New Typology for Economic Sectors with a view to Policy Implications

This paper is an attempt to tease out a typology of economic sectors based on a systems approach to innovation and economic growth that may be useful for policy analysis. The typology explored here revolves around novel products rather than ethereal knowledge-producing entities. This insight goes back to Allyn Young (1928) and Joseph Schumpeter (1934) who argued that the introduction of new goods was the engine of economic growth. More precisely, our typology of sectors focuses on novel products which are efficiency-enhancing within and between sectors through the market mechanism. The scheme revolves around the relationship between 'Enabling' and 'Recipient' sectors (which gives the typology its name: ER), and offers a lens for viewing and interpreting a substantive part of the mechanics of modern economic growth. The last part of the paper briefly discusses a few immediate policy implications, although it has the potential for greater use and value in this regard.     

关于资产证券化表外化有关问题的分析

资产证券化表外化的实现,要满足两个条件:一是向SPE的转让要满足会计上的真实出售,二是SPE不能成为转让人的连接对象。本文的内容是关于第一个问题的,并以美国的财务会计准则报告(第140号)为背景,通过分类归纳的形式,达到有利于理清脉络、把握原理、借鉴吸收、跟进规制的效果。     

员工的活性化与活性化的组织

职工队伍的活性化（empowerment)是全面质量管理中最为重要的概念之一，是职工参与的一种高级形式。活性化是指这样一种状态，即被激活的职工在规定的限度内，具有做决定和采取行动的知识、技能、职权和欲望。使组织的成员活性化是实现组织目标的关键举措之一。 本文着重讨论了活性化的含义、活性化组织的特征以及组织实现活性的各种途径。     

乌鲁木齐城乡统筹发展问题探讨

乌鲁木齐县作为首府的直辖县,发挥着缓解首府经济、社会与环境矛盾的重要作用。但是基于“大城市、小郊区”的现状,乌鲁木齐存在着城乡分割、二元结构逐步扩大的趋势,影响着首府经济、社会的和谐发展和乌昌经济一体化进程。本文在分析了乌鲁木齐二元结构现状和制约因素基础上,提出了构建乌鲁木齐城乡统筹发展的新机制。     

卓炯的剩余价值观与市场经济二重性

卓炯是我国著名经济学家,自1961年提出社会主义商品经济理论,直至1987年逝世,26年如一日,不懈追求,探索商品经济的本真。他的社会主义商品经济理论终于成为社会主义市场经济理论的一个重要思想来源,对我国,尤其对广东的改革开放起到了积极的思想基础作用。在卓炯的商品经济理论中,剩余价值二重性观点占有突出的地位。剩余价值二重性观点建立在他二重性分析方法的基础上,这种思想方法对我们今天认识、分析现代市场经济二重性特征有重要的价值与意义。     

Dual scaling and correspondence analysis of preferences, paired comparisons and ratings

The methods of dual scaling (DS) and correspondence analysis (CA) are used extensively in marketing research for analyzing categorical data. When applied to preferences, paired comparisons and ratings, dual scaling has been contrasted with correspondence analysis, as if the two techniques operated differently on these data. In this note, we show that correspondence analysis provides exactly the same solution as dual scaling once the data have been transformed by a so-called “doubling” with respect to the respondents.     

Why are shareholders not paid to give up their voting privileges? Unique evidence from Italy

Dual-class share unifications have typically been argued to be beneficial for voting shareholders, who are usually compensated for the loss of their superior voting privileges. However, no covenants exist that make this compensation mandatory for voting shareholders. In this paper, we examine a subset of dual class share unifications from Italy where, in the main, voting shareholders are not offered any compensation in lieu of the loss of their superior voting rights. We present a simple model describing the conditions under which the controlling voting shareholder will choose not to offer compensation to minority voting shareholders as part of a share unification. Our empirical results support the model predictions.     

我国政府投资效应的CGE模型分析——基于“刘易斯”宏观闭合框架下的模拟

以往国内利用可计算一般均衡(CGE)模型进行实证研究的文献,大多是假设中国处在资本充足、充分就业的新古典主义宏观闭合框架下,忽视了我国目前处于二元经济的客观事实。本文基于中国现阶段的基本国情,建立了一个刘易斯宏观闭合下的CGE模型,并利用该方法模拟了2008年末我国启动的政府投资(1.18万亿)对经济各个方面产生的影响。模拟结果显示:政府投资将会在未来几年之内拉动实际GDP增长1.83%、提升总消费2.1%、社会总投资9.89%、进口额2.09%、出口额2.14%,同时将带来约1805万的新增就业机会。     

Managing inventory with two suppliers under yield uncertainty and risk aversion

In this paper, we consider a single-product single-period inventory model in which the retailer can source from two suppliers. The primary supplier is cheaper but unreliable in the sense that it generates supply yield uncertainty, whereas the secondary supplier is perfectly reliable but more expensive. The reliable supplier's capacity is fixed and the retailer cannot order more than the quantity reserved in advance. We study the problem in the context of a risk-averse retailer who has to determine the optimal order quantity from the primary supplier and the optimal reserved quantity from the secondary supplier. We develop the model in the perspective of a low risk averse retailer and quantify the risk via an exponential utility function. We show by numerical experiments how the resulting dual sourcing strategies differ from those obtained in the risk-neutral analysis. We also examine the sensitivity of some model-parameters on the optimal decisions.
