Globalization,Gender And The Davos Man

Using Karl Polanyi's analysis of the social construction of markets in nineteenth- and early twentieth-century Europe, the paper applies his analysis to the formation of global markets in the late twentieth century. The paper argues that Polanyi's work needs to be engendered in order to take into consideration women's and men's different links to the market and to understand the construction of "economic man" gone global. The paper also addresses the feminization of the labor force across the globe and the possible effects on women's behavior and on the construction of "economic woman." The concluding section discusses alternative interpretations of this behavior.     

我国银行和地产类股价波动性对比研究

本文通过描述性统计和建立GARCH族模型,以2008年1月2日至2013年7月11日的银行和地产类股票日收盘价数据作为样本,对我国银行和地产类股指日收益率的波动性进行了对比研究。得到以下结论：银行和地产两类股票收益率序列都是平稳的,具有“尖峰厚尾”的特点,具有波动聚集性;两类收益率的波动均具有“长期记忆性”;均存在非对称效应。     

中日韩FTA的潜在经济影响研究——基于动态递归式CGE模型的研究

区域性FTA已经成为世界贸易自由化的新趋势,中韩日FTA的构建对于3国经济融合将产生巨大的推动作用。本文首先回顾了中日韩FTA的相关研究与谈判进程;然后分析了中日韩3国的贸易结构、特征与趋势;最后,结合FTA资本聚集效应,按时间序列构建动态递归式一般均衡模型,分析了中日韩FTA对3国国内生产总值、福利(EV)、外贸进出口、贸易条件等产生的各种潜在经济影响。     

广东省良种补贴绩效分析

本文概述了广东省良种补贴政策的实施情况,对由广东省农业厅和华南农业大学经济管理学院组成的调研组在广东省内韶关、清远、梅州、河源、湛江、茂名共6个市开展的问卷调查进行分析,共回收501份有效问卷。调查结果表明农村务农劳动力中中老年人占绝对主体,农民的受教育程度偏低;农民对良种补贴政策比较满意,对其认知情况良好,希望该政策能够保持且加大力度实行;大多数农民认为良种补贴政策有利于提高自身的种粮积极性和粮食产量,并提高和稳定他们的种植收入。同时,农民也认为良种补贴政策主要存在补贴金额不足和良种补贴品种单一这两个不足之处。     

A Frontier Approach to Testing the Averch–Johnson Hypothesis

The mathematical programming technique Data Envelopment Analysis is used to test the famous hypothesis of Averch and Johnson that utility regulation leads to overuse of capital because the regulated firm earns a return s greater than its cost of capital r, an implicit capital subsidy resulting in allocative inefficiency. Technical and allocative inefficiency are based on cost and production frontiers from 337 electric generating plants using 1970 data, and r is based on the Capital Asset Pricing Model. Significant capital overuse and general failure to minimize costs is detected, but a second‐step regression analysis finds no relationship between the overuse and the s–r subsidy. A small updated data set covering the period 1980–2004 suggests that overuse of capital is no longer a problem, a result that may be owing to recente deregulation and restructuring.     

深圳多功能自由贸易区的模式选择与制度设计

近年来，全球范围内的自由贸易区发展迅速，并且出现了向多功能综合型转型等新的趋势。我国各类特殊经济功能区面临着向规范的自由贸易区转型的选择。在深圳建立多功能、综合型自由贸易区，符合发展中国家自由贸易区转型的新趋势，有利于促进深港经济融合。借鉴国际自由贸易区的做法，深圳自由贸易区要建成一个规范的自由贸易区，需要对其进行科学合理的政策和制度设计。     

The Role of Local Agglomeration Economies and Regional Characteristics in Attracting FDI: Italian Evidence

The objective of this paper is to test for the importance of local agglomeration externalities in determining inward foreign direct investment (FDI) intensity, viewed as a measure of regional attractiveness to FDI. The links between the degree of FDI inflow penetration into Italy and its determinants at the regional level are examined using alternative fixed effects panel data model specifications, also extended to include spatial effects. It is found that sectoral and regional specificities are relevant in attracting inward FDI into Italy and the different effects of intra‐sector and inter‐sector spillovers can be distinguished. There is also evidence that the importance of agglomeration spillovers connected to the geographical distance varies across regions, indicating both substitution and complementarity effects from FDI inflows into neighboring regions.     

On the Application of Conditional Independence to Ordinal Data

A special log linear parameterization is described for contingency tables which exploits prior knowledge that an ordinal scale of the variables is involved. It is helpful, in particular, in guiding the possible merging of adjacent levels of variables and may simplify interpretation if higher-order interactions are present. Several sets of data are discussed to illustrate the types of interpretation that can be achieved. The simple structure of the maximum likelihood estimates is derived by use of Lagrange multipliers.
