Corporate discourse and environmental performance in Argentina

There is substantial research and policy interest in the relationship between firms and the natural environment, including how this relationship is influenced by regulators, international pressures, rival firms and stakeholder demands. With some exceptions, the ‘softer’ dimensions of environmental aspect management – how attitudes, beliefs and perceptions and the human factors drive corporate behaviour – have been understudied. The work that exists tends to be informal, and allows little scope for the statistical validation that is required for robust inference. This paper examines whether corporate values towards the environment affect a firm's environmental performance. It uses survey methods as well as content and discourse analyses of interview text and corporate reports and web sites to explore the links between managerial ‘mindsets’ and the environmental performance of the firms of which they are a part. Though the application is Argentina, the lessons learned can be generalized to other developing and industrialized countries. Copyright © 2006 John Wiley & Sons, Ltd and ERP Environment.

The stock closing calland futures price behavior: Evidence from the Taiwan futures market

This study examines the behavior of futures prices around stock market close before and after changes to the batching period of the stock closing call. On July 1, 2002, the Taiwan Stock Exchange expanded the length of the batching period roughly 10‐fold, from an average of 30 seconds to 5 minutes. This change presents an opportunity to analyze how a stock closing method affects the behavior of index futures prices. Empirical results indicate that an increase in the length of the batching period affects the return volatility and trading volume of index futures contracts around stock market close. Furthermore, preclose stock returns have a great impact on extended futures returns when the batching period of the stock closing call is long. © 2007 Wiley Periodicals, Inc.

Multinational firms, exclusivity, and backward linkages

How does the nature of contractual relationships between a multinational and its local suppliers affect backward linkages and welfare in the local industry? We address this question in a two-tier oligopoly model where a multinational transfers technology to its suppliers if they accept an exclusive contract that precludes them from serving its local rivals. Invited suppliers balance the benefits of gaining access to new technology and the derived demand of the multinational against the opportunity of selling to other local firms. Exclusivity reduces competition among local suppliers and can lower backward linkages and local welfare relative to autarky.     

不同所有制部门的代际收入流动性研究——基于劳动力市场分割的视角

代际收入流动性反映父代收入对子代收入的影响程度,是衡量机会公平的重要指标。研究结果显示,我国不同所有制部门的代际收入流动性存在显著差别。在党政机关、事业单位和国有企业等体制内部门工作的父代对子代收入的影响最大,其次为私营企业、外资企业和自我雇佣者等体制外部门,而来自集体经济部门的父代对子代收入的影响最小。子代个人特征差异对体制外部门和集体经济部门的子代收入差距的贡献超过65%,而对体制内部门与其他两个部门间子代收入差距的贡献只有不到50%。同时,代际收入流动性的程度差别和个人特征对收入差距的贡献在子代收入分布的不同位置上有不同表现。     

德国以色列国际科技合作情况研究

本文对德国和以色列国际合作关系进行了梳理,总结了两国主要的合作领域和合作项目,并运用科学计量学方法,对1996-2013年SCI收录的德国和以色列合著论文的时间序列、合作领域、主要的合作机构等进行了统计分析,揭示德以两国合作论文的特征,探讨两国科教合作特点。两国主要通过政府间、科研机构和大学进行合作,并成立了相关的基金会,为科研项目提供资金支持。我国应该在保持政府间合作的基础上,促进科研机构、大学之间的相互交流合作,设立相应的合作基金会,加强民间合作,积极发展多领域、多层次、多学科的全面合作,提升我国的科技创新实力。     

Localisation of Industry in Chile, 1895–1967: Mining Cycles and State Policy

Mining cycles have had an enormous impact in the evolution of the localisation of economic activity, in particular of industry, in Chile. The nitrate cycle was characterised by a labour‐intensive extraction process and activity which was geographically very concentrated. The copper cycle was geographically more dispersed and its activity more capital‐intensive. We stress the role played by the State in the latter de‐concentration due to the impact of regional development policies and assess the importance of factor endowments and agglomeration economies, in the localisation of the manufacture.     

Mozambique Metical Exchange Rate Dynamics: Evidence of Fractional Co‐Integration in the USA and South African Rates

This paper studies the exchange rate dynamics of the Mozambique metical with respect to the US dollar and the South African rand. However, instead of using standard I(0)/I(1) techniques, we use long memory and fractionally integrated and co‐integrated models. Our results indicate that the two exchange rates are highly persistent, with orders of integration equal to or above 1. They also seem to be co‐integrated, with an order of integration close to albeit above 0 but with an AR coefficient very close to 1. Thus, although the two series seem to be fractionally co‐integrated, shocks in the long‐run relationship between the two variables are persistent and take a long time to disappear.
