思想政治课教学的反思与回归

政治课教学的课堂不应该是没有生命力和灵性的“心灵屠宰场”,反思一下教学最终的价值取向如何,教学活动是预设还是生成,是否带有“绿色”,使政治课教学回归生活之中,让学生享受学习的乐趣,张扬自己的个性,体验人生的价值。     

课堂环境中加大口语语言输入的效果研究

如何有效地提高学生口语能力是大学英语教学中重要课题。本实验以非英语专业学生为研究对象,在有限的课堂教学时间内通过加大口语语言素材的输入,提高学生的口语交际能力,以寻求一种有效的教学模式。     

如何让学生带着情感上好英语课

基础教育课程改革的一个重要方面是把培养学生的情感列入课程教学目标。现代大学英语教学要求我们在英语教学中不但要重视培养学生的语言知识和语言技能,更要关注学生情感态度的发展。     

Pricing-to-market tests in instrumental regressions: Case of the transportation equipment industry

Pricing-to-market (PTM) theory suggests that exporting monopolistic firms adjust their destination-specific mark-ups in the face of exchange rate shocks. A large proportion of the existing evidence for PTM comes from Wald tests applied to OLS- and IV-estimated parameters of single-equation models. Such tests can seriously over-reject in the presence of endogeneity and weak instruments so that some of the available results supporting PTM could be spurious. In this paper we revisit the PTM evidence for Japanese and German exporting firms in the transportation equipment industry. Using the model of Marston (1990), we apply exogeneity and LR-LIML-based tests for which the error probability is controlled irrespective of the quality of the available instruments. Our results show right-hand-side endogeneity in almost all of the examined PTM equations. In addition, we find that statistical decisions often differ depending on whether they are based on the traditional Wald test or on our proposed test.The authors would like to thank Philippe Barla, Jean-Thomas Bernard, Christos Constantatos, Larry Schembri, seminar participants at the Bank of Canada, and two anonymous referees for useful comments and suggestions.

Policy matters. The long run effects of aggregate demand and mark-up shocks on the Italian unemployment rate

This paper estimates a VAR including labor productivity, real wage and unemployment rate, to identify the dynamic effects of technology, demand, and mark-up shocks, respectively, on the Italian labor market. Identification is achieved by imposing recursive restrictions on the matrix of long run multipliers. Our results show that both mark up and aggregate demand shocks permanently reduce the unemployment rate. Finally, technology shocks do not significantly affect the unemployment rate in the long run. These findings convey important policy implications: expansionary aggregate demand and deregulation policies reducing the mark up permanently decrease the Italian unemployment rate.Jel classification: C32, E32, J29This paper has been produced as part of a CEPR Research Network on New Approaches to the Study of Economic Fluctuations.

“知识分子负担”与家务劳动——劳心与劳力、性别与阶级之一

20世纪80年代关于“知识分子负担”的讨论凸显了脑力劳动（业务工作）和体力劳动（家务劳动）的矛盾,使家务劳动的问题成为一个阶层的特有负担,而遮蔽了性别的问题。重读80年代的小说《人到中年》可以读出以下问题：家务劳动在话语上怎样变成了一种负担？陆文婷为什么只能代表知识分子,而不是女性？谁是家务劳动理想的、合适的承担者？“知识分子负担”的话语如何为保姆进城搭台？对小部分家庭而言,雇佣家务劳动是用阶级的关系“解决”家务劳动中性别分工的问题和家务劳动社会化不足的问题。社会主流对家务劳动的定位、认识和处理反映出改革时代的现代化进程中,脑体、城乡和男女这三组社会差别的重构。     

Stock prices,production and interest rates: Comparison of three European countries with the USA

This paper investigates the relationships between stock returns, changes in production, and changes in interest rates in three European countries: France, Germany, and the United Kingdom. The results obtained using annual data are much more conclusive than those obtained using quarterly data. Stock returns are affected by current changes in interest rates and by future changes in production. The dependence on changes in interest rates seems to be higher than on changes in production. Furthermore, the influence of future changes in production on stock returns diminishes substantially when contemporaneous changes in interest rates are taken into account. With reference to these points, the European markets behave in a similar fashion, but are in sharp contrast with the U.S. market.I am very grateful to Kay Davidson, Patric Hendershott and two anonymous referees for useful comments and suggestions.

当代农民工生活状况分析

当代农民工的生活面临着很多困境,如工资拖欠、子女教育问题等。这些状况的存在,不仅给农民工带来了经济损失和精神痛苦,也对正常的社会经济秩序带来了不良影响,引起了政府的高度重视。     

职业技能培训对农民阶层地位获得影响的实证研究

我国在由计划经济向社会主义市场经济转型的过程中,个人自致性因素对阶层地位获得的影响日益突出。在众多的个人自致性因素中,职业技能培训是最重要的个人自致性因素之一,其对阶层地位获得发挥着举足轻重的作用。笔者通过实证研究证实：职业技能培训对农民阶层地位的获得存在显著影响。为了更好地推进农民的职业技能培训,一方面要充分发挥政府、企业、社会组织和农民个人等各个方面在农民职业技能培训中的作用,建立社会协同培训的格局;另一方面,在开展农民职业技能培训内容的设计和实施时,必须充分考虑到不同培训对象的不同需求,增加职业技能培训的针对性。     

New evidence on the convergence of international income from a group of 29 countries

This paper updates and extends the time-series evidence on the convergence of international incomes using a set of 29 countries over the period 1900–2001. Time-series tests for stochastic convergence are supplemented with tests which provide evidence on the notion of “β-convergence” predicted by the Solow model. The evidence indicates that the relative income series of 21 countries are consistent with stochastic convergence, and that β-convergence has occurred in at least 16 countries at some point during the twentieth century. Further examination of the properties of the β-convergence test provides anecdotal evidence of conditional convergence in three additional countries for which the convergence hypothesis was initially rejected. Consideration of convergence clubs strengthens the evidence in favor of convergence. Analysis of the cross-country dispersion of incomes over time also suggests that convergence has occurred over the 1900–2001 period, particularly within certain clubs, with structural breaks associated with World War II in many countries causing a break in the convergence process.
