湖南经济增长与消费、投资、出口的长期均衡和短期波动关系

利用协整技术分析了湖南消费、投资、出口与经济增长的长期均衡与短期动态关系.在协整检验的基础上,建立了各变量之间的长期均衡关系模型.并通过自回归模型和误差修正模型,对各变量之间的长期和短期因果关系进行了Granger检验.研究结果表明,投资与湖南经济增长之间存在显著的长短期因果关系,因此保持投资的持续稳定增长是湖南经济增长的最重要的宏观经济政策.

TEM-4完形填空的考点效度分析

本文以TEM-4改革后至今的6年完形填空试题（2005-2010年）作为研究对象,从考点层次和考点因素的角度,分析和探讨TEM-4完形填空的考点效度及其对英语专业基础阶段教学的启示。分析结果表明改革后的TEM-4完形填空具有较高的考点效度,在考点层次上侧重对受试者句子和语篇层次的考查,而在考点因素方面意义因素占据了主导地位。从2005-2010年TEM-4完形填空的变化趋势来看,TEM-4完形填空正逐步将其考查重点更多地移向语篇层次和意义因素,这一变化将使它的考点效度进一步提高。

不同来源地外资对中国技术进步影响的实证分析

首先测算出中国的技术进步指数,然后应用协整理论检验技术进步与来源地为香港、美国、日本和欧洲的4组外资的长期均衡关系,并建立误差修正模型考察4组外资对中国技术进步的短期影响,最后利用Granger因果关系检验识别4组外资对中国技术进步的影响程度。得出的结论是:4组外资在长期对中国技术进步都有积极的影响,在短期对中国技术进步的影响不显著且具有较大的波动性,其中美资对中国技术进步的影响最强。     

Fiscal policy and stock market efficiency: An ARDL Bounds Testing approach

The aim of this paper is to investigate the semi-strong market efficiency hypothesis with respect to fiscal policy information, in the context of the Bucharest Stock Exchange. Taking into account that macroeconomic data series of emerging countries usually have a limited size and may be plagued by inconsistencies and structural breaks, this paper proposes an ARDL Bounds testing approach for studying the relationship between stock returns and lagged macroeconomic variables. Moreover, this approach allows us to examine both the long and short-term relationship between fiscal policy and stock returns. The results indicate that, in the long run, stock prices fully and efficiently reflect information on past fiscal policy. However, in the short run, the Romanian stock market reacts efficiently only to unexpected fiscal policy news, while anticipated fiscal policy information displays a significant lagged relationship with current stock returns. In addition, the results also showed that monetary policy information is not incorporated efficiently into stock prices, both in the short and the long run, and its impact on stock returns is larger than the one exerted by fiscal policy.

Preparing undergraduate students for the Major Field Test in Business

Many business programs address the learning of undergraduate students with an exit exam. A reference librarian and the business school faculty created an online test preparation study guide (or LibGuide) which included no-cost resources that were readily available yet academically authoritative to aid students in studying for the Educational Testing Service Major Field Test in Business at an Association to Advance Collegiate Schools of Business–accredited college in northwest Georgia. The findings indicated that while some graduating business seniors did use the LibGuide materials, many were overwhelmed with the amount of material available and believed studying would not be beneficial to their performance on the exit exam. Discussion and areas for future research are presented.
