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。

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.     

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。     

Publish or Perish? The Increasing Importance of Publications for Prospective Economics Professors in Austria,Germany and Switzerland

Abstract. Tenure decisions depend, among other factors, on a candidate's career age and publication record. We associate publications with journal articles indexed in EconLit and measure publication output in equivalents of both top‐five journal articles and European Economic Review (EER) articles. We find that the average age of a professor in the year of his/her first appointment is 38, i.e. he or she is appointed approximately eight years after completing the PhD. Between 1970 and 2006, the average publication record at the time of the first appointment is equivalent to 1.5 standardized top‐five articles or 2.3 standardized EER articles. Publication records vary across subfields and have become more substantial over time. We predict that someone aspiring to a tenured position after 2011 should aim at an equivalent of four standardized top‐five articles or six standardized EER articles.     

跨国公司与东道国当地企业的合作方式及其经济内涵

跨国公司与东道国当地企业的合作存在五种形式：一是与供给商的合作;二是与客户的合作;三是与竞争者的合作;四是与技术伙伴的合作;五是具有外溢效应的合作。采用何种形式的合作,取决于TNC要实现的目标以及SME的合作能力;为建立与TNC更加紧密的合作关系,在东道国政府制定相关鼓励政策的同时。SME还应努力提高人员素质和技术水平,以增强自身的合作能力。
