Effect Sizes in Qualitative Research: A Prolegomenon

The American Psychological Association Task Force recommended that researchers always report and interpret effect sizes for quantitative data. However, no such recommendation was made for qualitative data. Thus, the first objective of the present paper is to provide a rationale for reporting and interpreting effect sizes in qualitative research. Arguments are presented that effect sizes enhance the process of verstehen/hermeneutics advocated by interpretive researchers. The second objective of this paper is to provide a typology of effect sizes in qualitative research. Examples are given illustrating various applications of effect sizes. For instance, when conducting typological analyses, qualitative analysts only identify emergent themes; yet, these themes can be quantitized to ascertain the hierarchical structure of emergent themes. The final objective is to illustrate how inferential statistics can be utilized in qualitative data analyses. This can be accomplished by treating words arising from individuals, or observations emerging from a particular setting, as sample units of data that represent the total number of words/observations existing from that sample member/context. Heuristic examples are provided to demonstrate how inferential statistics can be used to provide more complex levels of verstehen than is presently undertaken in qualitative research.

美联储前瞻性指引对新兴市场国家的溢出效应研究

基于前瞻性指引溢出效应的相关理论,选取17个代表性新兴市场国家为研究对象,运用面板向量自回归(PVAR)模型实证分析美联储前瞻性指引对新兴市场国家的溢出效应.结果表明:美联储前瞻性指引在短期内对新兴市场国家金融市场具有一定的冲击,在长期内对新兴市场国家经济增长存在滞后的正向作用.新兴市场国家应采取应对策略,做好风险识别和预警,加强预期管理,增强货币政策协调和合作,有效防范和化解外溢影响.     

Institutionalism and Econometrics: Toward a Meaningful Synthesis

For the last twenty years, the world economy has evolved at a great speed. Every good, capital asset, and knowledge is mobile and induces more competition. Innovation in commodities is a complex process that requires more cooperation. To innovate in the knowledge economy, firms nowadays must establish “win-win situations” for individuals in creating networks. These networks are useful for firms in order to come up with innovative strategies. The building of networks enables the interactions between agents, the environment, and institutions. The interdependence of agents and institutions is not new to evolutionary theory (Commons 1931 Commons, John R. “Institutional Economics.” American Economic Review 21, 4 (1931): 648–657. [Google Scholar]; Veblen 1898 Veblen, Thorstein. “Why Is Economics Not an Evolutionary Sciences?” Quarterly Journal of Economics 12, 2 (1898): 373–397.[Crossref] , [Google Scholar]). However, I argue that institutions must be more flexible than ever before in order to help agents adapt to the modern knowledge economy. On the basis of the role of meso-networks, I propose new long-run specialization and short-run competitiveness that will promote greater efficiency and equality around the world in relation to firms and countries exporting industrial goods into world markets. Within the innovative networks, I analyze the role of two different actors: (i) the “economic leader” who has a long-run strategy and (ii) the “go-between leader” who knows how to diffuse “useful information” to actors to help them innovate in new products, services, or processes.     

FDI溢出效应对我国流通服务业自主创新的影响研究

本文从流通服务业FDI溢出途径入手,研究了FDI溢出效应对我国流通服务业自主创新的影响机制。FDI溢出效应通过示范、竞争、产业关联和人力资源流动四个途径对我国流通服务业的自主创新产生影响。而本土流通企业通过企业的社会网络,利用自身的吸收能力消化外资企业的溢出成果并实现再创新。本文认为,要有效利用FDI溢出效应,提高本土流通企业自主创新能力,需要政府在保护知识产权、改良产业政策等方面做出努力,创造良好的政策环境,同时需要流通企业更新观念、引进人才、提高自身吸收能力。     

Static and dynamic efficiency of pollution control strategies

A great deal of the economic literature on pollution control strategies concentrates on the efficiency of environmental policy instruments. Most analytical studies in this field show that market instruments are more efficient with respect to the cost of pollution abatement of a given number of polluters than non-market instruments. According to several analytical studies, market instruments should also be more efficient with respect to innovation in pollution abatement equipment than non-market instruments. In the empirical literature a great number of case studies exist with estimations of the savings of abatement costs of market instruments in a situation without technological progress. Empirical studies about the impact of environmental policy market instruments on the abatement costs in situations with technological progress are lacking.The purpose of this paper is to fill this gap. The paper deals with an empirical estimation of abatement costs for the emission of SO₂ of coal-fired electricity units in the Netherlands from 1985 to 2000. First, the working of market instruments and non-market instruments (the existing environmental policy of the Dutch government) is simulated in a static situation. Second, we analyse the learning effects of flue gas desulphurization. The efficiency advantage of market instruments turns out to be larger in a situation of technological progress than in a static situation.

我国经济增长对二氧化碳排放影响的实证分析——基于一般均衡模型的分解方法

文章基于动态的一般均衡模型分析框架,利用中国1997--2040年的宏观经济数据和CO2排量数据,试图回答以下两个问题：第一,中国未来三十年的经济增长对CO2污染排量会有怎样的影响？第二,如何制定合理的政策实现中国政府承诺的CO2减排量？研究结论表明,如果实行正确的控污措施,在未来的30年里中国经济增长将不会造成CO2排量大量增加。通过对CO2排放量进行Divisia分解所得的结构效应和技术效应显示,污染排放量的有效控制可以通过重点减排活动、发展清洁燃料产品以及改进其使用技术得以实现。
