A股市场过度反应的新证据——基于A股和H股估值变化的视角

传统的检验市场过度反应的方法是采用De Bondt和Thaler构造的赢家组合和输家组合,通过检验赢家组合和输家组合的超额收益率来判断市场是否存在过度反应。有别于传统的检验市场过度反应的方法,本文基于我国股票市场上A股和H股估值变化的特殊视角,实证分析了我国A股市场存在的过度反应现象。     

TOWARD BRIDGING THE GAP BETWEEN THEORY AND EMPIRICAL REALITY

Introductory (i.e. first year) undergraduate learners often perceive economics to be remote from reality and overly theoretical, leading to a lack of motivation and enthusiasm to study economics. A general survey of curriculum practice reveals that lecture materials and the pedagogic approach to teaching introductory economics often do not place the current “mainstream” economic theory into its philosophical context. The result being that the learners are unable to bridge the gap between abstract economic theory and empirical reality. This paper argues that research into effective teaching and learning should focus not only on learner characteristics but also on curriculum content and its philosophical underpinnings, in order to research why students hold these negative perceptions. The paper recommends that introductory undergraduate teaching needs to engage in a critical examination, with the learner, of the philosophical underpinnings of “mainstream” economic theory and to introduce debates about the implications of these into the curriculum. This would create exciting new opportunities for teachers and learners to explore the connections between economic theory and social science in general and should come a long way in changing the negative perceptions of introductory undergraduate economics.     

股权结构对上市公司并购绩效影响的实证研究

本文结合我国上市公司股权结构特征,分析了股权结构对并购绩效的作用机理,并对其进行实证研究。研究表明:国有股东属性与公司并购绩效正相关;第一大股东持股比例越高,并购绩效越差;其他大股东的制衡能力越强,公司并购绩效越好。     

CORRECTING FOR SAMPLING BIAS IN EDUCATION PRODUCTION FUNCTIONS

Sample selectivity bias arises in the estimation of education production functions when the process of selecting the sample is not independent of the value of the dependent variable. In this study, the dependent variable was a student's retention of microeconomics knowledge after a period of 6 weeks following the final examination. Potential sampling bias arises from a student's decision to participate or not to participate in the research. Results obtained from the Heckman selection model indicated minor sampling bias. Student ability and the male dominance in economics performance were overestimated in the OLS model. Student effort was underestimated.

Waves and Determinants in Mergers and Acquisitions: The Case of Latin America

This article contributes to the current literature on mergers and acquisitions (M&As) by identifying the existence of waves and the determinants of M&A activity in the economies of Argentina, Brazil, Chile, Colombia, Mexico, and Peru. From a sample of 2,391 M&A announcements reported by Thomson One on these countries, applying the methodology proposed by Harford (2005), evidence of M&A waves is found for the periods 1995–2002 and 2003–2010, as reported for other regions in various international studies. After controlling for economic and business environment variables, as well as for profitability and book-to-market variables at the industry level, we find evidence that supports neoclassical theory as a main explanation for M&A activity but not for the misvaluation effect.     

Measurement of Quality of Life and Well‐Being in France: The Drivers of Subjective Well‐Being

Ever since the publication of the Stiglitz Report, France has been heavily involved in the measurement of well‐being. The French Statistical Institute (INSEE) has expanded the scope of its existing surveys. It has also launched an innovative experimental survey which, drawing upon a single statistical source, aims for the first time to explore the different dimensions of both objective and subjective quality of life, as highlighted in the Stiglitz Report. It allows us to study, at the individual level, correlations between these dimensions and the accumulation of deprivations. It has enabled us to better understand the links between determinants generally referred to as objective dimensions of quality of life (such as health or education) and subjective well‐being. This information is of paramount importance for policy makers who cannot act directly on the level of people's satisfaction but can only act upon the levers of objective dimensions. This paper presents the main findings of the experimental survey.     

恶劣环境对船舶焊接的影响

在船舶建造过程中焊接工作量约占全部的30%~40%，焊接是保证质量的重中之重。焊接质量出问题，就可能造成严重的后果。我厂沿江堤而建，空气中湿度大，工作条件差。密集性气孔很严重。所以，在这种情况下，对我厂焊接质量控制提出更高的要求。     

What is extreme about Mises’s extreme apriorism?

There is something extreme about Ludwig von Mises’s methodological apriorism, namely, his epistemological justification of the a priori element(s) of economic theory. His critics have long recognized and attacked the extremeness of Mises’s epistemology of a priori knowledge. However, several of his defenders have neglected what is (and what has long been recognized by his critics to be) extreme about Mises’s apriorism. Thus, the argument is directed less against Mises than against those contributions to the secondary literature that assert his methodological moderation while overlooking what the most prominent critics have found extreme about Mises’s apriorism. Defending Mises as a merely moderate apriorist because he held only a narrow part of the foundation of economics to be a priori is a straw-man defense against criticisms of his apriorism as epistemologically extreme.
