Diversity Analysis of Structural Change Based on the Canadian Input–Output Tables

This article presents some of the results of a study conducted at Statistics Canada that involved the analysis of the variability through time of input–output structures. All structures have been analyzed in current and constant prices over the period 1961–84, but only the results about the industries' input structures in current prices are reported in this article. Structural changes are assessed over time horizons of 1, 2 and 5 years, using the Kullback, cross-entropy index formula. Structural changes in the current prices input structure are decomposed into a price and a quantity component, following a new decomposition of the entropy formula. It is shown from that decomposition that the traditional analysis of the variability of constant prices input–output structures may be quite misleading. The authors have found that structural changes generally follow a smooth path through time and tend to be cumulative in the long run, with some cyclical fluctuations in the short term. Some of the structural changes appear to be due to statistical events (establishment moves across industries, changes in methodologies, etc.) rather than reflecting real phenomena. The quantity component of structural change appears to be more important than the price component in almost all time periods and time spans, except when the Canadian economy was subjected to important price shocks during the 1970s.     

人民币汇率波动对NFDI波动的影响及其检验

本文通过对我国NFDI资本流动性及其波动性的计算,检验了人民币/美元汇率波动对NFDI波动性的关系。通过实证分析表明,人民币汇率的波动将导致NFDI资本流动的明显不稳定。在理论研究的基础上,引申出其政策含义：在国际资本流动不断加大的今天,我们必须维护人民币/美元汇率的稳定,这样对于有效引导NFDI的资本流动和维护金融稳定都具有重要的意义。     

Reciprocity,Multiplexity, and Exchange: Measures

We introduce measures and statistical tests for multiplexity and exchange that are modeled on similar ideas developed for reciprocity quite early in the history of social network research. As properties of a multi-relation network, multiplexity, and exchange have almost as ancient a history as reciprocity, but have not been as intensively investigated from a methodological perspective. Multiplexity refers to the extent to which two ties, for example, advice and friendship, coincide over population; that is, do respondents name the same people as friends as the persons they nominate as individuals from who they seek advice. Exchange refers to the extent to which a tie of one type directed from person i to person j is returned by a tie of another type from j to i. We conceive of the current paper as the first part of a two-part paper, wherein the second part explores specific theoretical models for multiplexity and exchange.

Investor Relations （IR） in Business Communication on the Example of Poland

This paper focuses on investor relations （IR） as an element of companies＇ communication with the external environment. It shows the place and role of IR in communication with the general market, and the stock exchange market in particular. The study is illustrated with an example of IR in Poland, a relatively new European Union （EU） member state and an emerging market. As can be seen, IR goes beyond the traditionally understood maintenance of communication with the capital market. It is also shown that the main role of IR ought to be the reduction of investment risk and enhancement of the companies＇ value, which is of particular significance in light of the current globalization of capital markets. It has been found that Polish companies, especially those listed on the Warsaw Securities Exchange （WSE）, commonly rely on IR as a means of communication with the environment. And yet, as the results of the analysis show, the quality of that communication is still far from satisfactory, despite efforts undertaken by various external entities to encourage more focus on the development of IR, or understanding of the company＇s relevant staff of its important role.     

人民币资本项目可自由兑换目标下的“双Q”制度研究

我国QFII和QDII制度是人民币资本项目可自由兑换的重要阶段。QFII和QDII近年取得较快发展,但亦面临QFII规模偏小、我国资本市场对其吸引力不够,QDII缺乏海外投资经验、亏损严重等问题。需要完善资本市场功能,为QFII制度的实施营造良好的投资环境;加强QDII风险管理,提高QDII境外投资管理能力;加强监管,健全和完善＂双Q＂制度,促进跨境证券投资持续健康发展。     

市场结构、汇率转嫁与出口

汇率变化是影响出口贸易的重要因素。在传统的国际贸易理论中,虽然对汇率变化影响出口贸易的机制进行了详细分析,但它没有考虑到市场结构的影响。本文从市场结构的角度出发,分析在不完全竞争的市场结构下,拥有市场势力的企业的决策怎样影响到汇率的变动和产品的出口。本文的研究结果表明,在不完全竞争的市场结构下,汇率转嫁是不完全的,因此,只有大的持久的汇率贬值或升值才会对出口贸易量产生明显的效应。     

对当前我国外汇储备基金实现投资增值的思考

外汇储备必须在满足流动性和安全性前提下,拓展投资渠道,控制投资风险,提高投资收益.近几年来,我国外汇储备持续高企,而外汇储备基金投资却只有3%的营运收益率.本文分析了我国外汇储备基金投资增值的现状,从区分管理功能和投资功能,组建高效基金运营模式;设定投资基准和投资限额,控制和规避投资风险;优化外汇储备的货币结构和资产结构,拓宽投资渠道;加快培养吸纳国际金融市场操作人才,完善有关法规等几个方面提出了改进外汇储备基金投资增值的对策.     

开放条件下国际资产定价模型的解析与检验
