Ethnic divisions and the effect of appropriative competition intensity on economic performance

This paper features a growth model with an appropriative contest and a common-pool investment game between politically organised rival ethnic factions. I determine how the long-run equilibrium coalition shapes incentives to invest, show the existence of a unique steady state, and investigate how the ease to capture rents affects economic performance. The use of numerical simulations concerning a global sample of countries demonstrates that contest intensity can sometimes be beneficial, despite wasteful grabbing behaviours, due to a mechanism related to the concentration of power. When rents become easier to capture, dominant groups have an incentive to expand their influence further. This adjustment can be beneficial as these groups contribute most to capital accumulation.     

Management in production: from unobserved to observed

Are productivity estimates good proxies for unobserved management? And, does management affect production in a neutral and monotonic fashion as assumed by these proxies? We use Bloom and Van Reenen’s management data to show that two popular proxies, fixed effects and inefficiency scores, correlate with observed management practices. We find that the correlations are positive but weak. Also, management explains only a fraction of the proxies’ variances. The data rejects the assumptions of neutrality and monotonicity. Last, our results suggest that management has characteristics both of a technology and an input.     

Measuring populist discourse with semantic text analysis: an application on grassroots populist mobilization

Populism is a concept employed to qualify the political behavior of a large number of actors at a worldwide scale, with scientists classifying the latter into populists and non-populists according to dimensions such as ideology, strategy, discourse, economic policy, and even style. This article analyzes existing schools of thought on the nature of populism and argues that conceptualizing populism as a specific type of anti-elite discourse in the name of the People is both conceptually and methodologically the most coherent and useful way to understand the phenomenon. Additionally, it suggests discarding crude, dichotomous classification in favor of a gradated view of populist mobilization by means of quantifying populist discourse and observing its spatial and temporal variation. It adds value to current methods of measurement by demonstrating why and how clause-based semantic text analysis can provide optimal quantitative results while retaining qualitative elements for mixed-methods analysis. Aiming, moreover, at expanding the scope of populism studies by overcoming a narrow view that focuses exclusively at party system developments, it applies semantic text analysis to the study of grassroots mobilization during the Great Recession. Results point to the wide use of populist discourse on the part of movement activists seeking an inclusive language when framing disparate social grievances in a given constituency, a finding with important implications with regards to how populism can facilitate straddling the divide that purportedly distinguishes institutionalized party system behavior from the social movement milieu.     

基于建构主义理论的大学英语词汇教学

建构主义理论认为:知识是个体主动建构的,是个体与他人通过磋商并达成一致的构建过程。在这种理论的指导下,学习观和教学观都发生了深刻的变化,这种理念强调以学习者为中心,注重互动、合作的学习方式,尊重个人意见和学习者已有的知识经验;同时教师的作用转变为设置适当的学习情境,鼓励学生反省与思考,帮助学生进行知识的意义建构。本文以第二版的《新视野大学英语》第二册第七单元TextA的课文为例,以建构主义学习理论为指导,在把握课文篇章意义和结构的基础上,遵循认知规律,设计不同层次的学习活动,让学习者循序渐进地完成这些任务,在头脑中构建词汇的意义和应用,最终培养同学的创造性,提高同学自主学习的积极性。     

国际证券市场联动程度的实证分析

20世纪80年代以来,通过国际证券投资分散风险已经形成一种可行手段,然而,随着全球经济一体化趋势的强化,国际证券市场也正在经历着一体化趋势,证券市场联动关系越来越明显,这必然会使国际投资多样化空间变小,进而会侵蚀掉国际多样化投资收益.有鉴于此,本文使用协相关参数分析、平稳性检验、多元协整检验、协整向量参数零配载限制检验、基于VECM的Granger因果性检验等计量技术测度国际证券市场联动程度,为国际证券投资提供量化参考.
