Risk Aversion,Uncertain Information,and Market Efficiency

Abstract. We reexamine and extend tests of the uncertain information hypothesis (UIH) proposed by Brown, Harlow, and Tinic (1988, 1993). We find that their empirical results are sensitive to the sampling procedure employed and that their particular methodology does not sufficiently distinguish between event and nonevent periods. When the sampling procedure is modified to identify only relatively large, isolated events, the test results generally do not support the UIH. Instead, significant price shocks are consistently followed by short-lived price reversals. We observe this behavior following positive and negative events regardless of whether the event is classified as risk increasing or risk decreasing.     

Dynamic analysis of stock return volatility in an integrated international capital market

This paper examines the dynamic behavior of the stock return volatility for Canada, Japan, Germany, and the United Kingdom. The evidence indicates that international stock return volatility is mainly influenced by the U.S. stock return volatility and the exchange rate volatility, supporting the international capital market integration hypothesis. There seems to be some correlation between stock return volatility and macroeconomic volatility, but the effect is relatively weaker. In addition to the economic fundamentals, the noise component is found to be time varying, confirming the AR(MA)CH specifications in the stock return models.

不完全竞争、交易效率和证券风险

本文提出了一种崭新的理论观点———不完全竞争的市场结构是证券风险的一个重要来源,并利用市场数据进行了实证分析。此外,本文还发现不完全竞争的市场结构会通过影响买卖双方的交易策略而降低市场的交易效率。     

我国股市与货币需求的相互影响分析及政策涵义

运用协整、弱外生性和因果关系检验对我国股票市场与货币需求的关系进行的实证研究发现,股市不影响M2的总量但影响其结构;M1对股市不产生直接影响,而M2对股市的直接影响处于有与无的临界状态;M1、M2均通过GDP对股市产生间接影响,但没有形成利率传导机制,我国股市是关于协整向量的弱外生变量.基于以上结论提出了相应的政策建议.

Research on Basic Design Education: An International Survey

This paper reports on the results of a survey and qualitative analysis on the teaching of ‘Basic Design’ in schools of design and architecture located in 22 countries. In the context of this research work, Basic Design means the teaching and learning of design fundamentals that may also be commonly referred to as the Principles of Two- and Three-dimensional Design. The body of knowledge associated with Basic Design may be regarded as part of the general theory of teaching and learning design as practiced in many design schools and which has its origins in the classical design schools such as the Bauhaus. In the author’s perception and practice, the pedagogy of Basic Design promotes a holistic, creative and experimental methodology that develops the learning style and cognitive abilities of students with respect to the fundamental principles of design. This includes an understanding of the elements of shape, colour, texture, light, and rhythm in a manner complementary but usually unrelated to the common design methods teaching approach. As is well known among design practitioners, including architects and industrial designers, a deep understanding of the purpose of these fundamental design elements and principles is still relevant to contemporary design practice. The main objective of the research described in this paper was to determine the status and development of Basic Design pedagogy in a significant number of contemporary design schools. On the basis of the results of two surveys conducted in 2001–2002, this paper will identify and illustrate interesting aspects concerning the programmes and organisation of courses delivered by teachers of ‘Basic Design’. This work will also survey the viewpoints of Basic Design teachers in elementary years of design courses and of those teaching design through projects during the subsequent years of the same courses. Interestingly, the design project teachers surveyed in this research expressed a desire to be more involved in the teaching of Basic Design fundamentals which indicates strongly that Basic Design principles are still relevant in contemporary design education terms as they have ever been and that more research is needed in order to better understand and apply the related pedagogy.     

基于资本配置效率的资本市场发展与经济增长——以汽车制造业上市公司为例的实证研究

研究资本市场发展与经济增长的关系,是揭示资本市场对资本配置效率的一个重要研究视角。以汽车制造业上市公司为例,对投资增长与资本回报率之间关系的实证检验,发现我国股票市场的资本配置效率低下,并导致其促进经济增长的功能微弱。造成我国资本市场资本配置效率低下的直接原因是上市公司绩效的非稳定性和经营非持续性。因此,要实现我国资本市场引导资金流向、优化资源配置,促进经济增长作用的功能,必须提高上市公司业绩稳定性和经营持续性。     

基于融资视角的中国金融结构与金融稳定研究

通过对中国金融运行的实证检验和分析发现,以银行中介和金融市场划分的两种金融结构各有优势,只要能够满足金融资源高效配置的金融结构都符合经济发展的需要,不必对金融结构进行人为的割裂。中国的金融体系存在着转化投资的高效率和资源配置的低效率这样一对突出矛盾,其主要原因是金融资源的配置失当,这是当前中国金融稳定的潜在威胁,解决问题的关键是要对金融体系进行市场化改革并完善基础设施建设。     

国际收支与金融市场效率问题的探讨

以“逆差 顺差”为特点的美国国际收支结构是很难长期持续的,美国经常项目很可能会经历趋向平衡的调整过程。由于中美两国国际收支结构存在较强的互补性,美国国际收支结构的调整对目前中国国际收支结构提出了严峻挑战。金融市场的行政分割、金融资源结构及流向的不合理是影响中国国际收支结构失衡的重要因素,因此中国应该完善和发展金融市场,积极主动地调整目前失衡的国际收支结构以应对美国国际收支结构调整可能给中国经济发展带来的不利影响。
