BUSWORLD ASIA之沧桑

参展主体正在从整车企业变成零部件企业吗?获得那些名头甚大、内容可疑的大奖还是参展目的吗?到底谁来观展,是看门道还是看热闹?曾经作为国内客车业最高规格的展会——BUSWORLD ASIA迎来了自己的十周年。在这十年间,经由一间原本名不经传的行业外展览公司的成功商业运作,此展赫然位列国内客车业的主流展会之首。几乎每年春季,都会在客车行业掀动一轮热议话题。

WILL BUSINESS CYCLES IN THE EURO AREA CONVERGE? A CRITICAL SURVEY OF EMPIRICAL RESEARCH

Abstract.  This survey of business cycle synchronization in the European monetary union focuses on two issues: have business cycles become more similar, and which factors drive business cycle synchronization. We conclude that business cycles in the euro area have gone through periods of both convergence and divergence. Still, there is quite some evidence that during the 1990s business cycle synchronization in the euro area has increased. Higher trade intensity is found to lead to more synchronization, but the point estimates vary widely. The evidence for other factors affecting business cycle synchronization is very mixed.

不稳定的GO世界

当今世界,从理论上讲,全球经济、政治大权握于G20手中。但实际上,全球领导力并不存在,G20内部纷扰不断,分歧严重,举凡贷币与财政政策、汇率与全球经贸不平衡、气候变化、贸易金融稳定、国际贷币体系、能源、食品和全球安全问题,莫不如此。     

GO跟着萌货去旅行

萌货1号：国宝熊猫推荐地一：成都·大熊猫繁育基地其实,国内最著名的看熊猫去处是卧龙熊猫基地,不过,去成都的大熊猫繁育研究基地看熊猫对于绝大部分游人来说更方便。在成都熊猫基地,可以近距离地接触到各种或卖萌、或不停埋头吃竹子的熊猫,还有机会看到他们的产房、别墅和剧场等很多新鲜的事物。     

GO含量对GO/NBR/MMA复合材料组织和性能的影响

目的:研究氧化石墨烯(GO)含量对氧化石墨烯/丁腈橡胶/甲基丙烯酸甲酯(GO/NBR/MMA)复合材料组织和性能的影响。方法:通过球磨法制备不同GO含量的GO/NBR/MMA复合材料,并通过自然沉降实验、Zeta电位测试、Raman光谱测试、热失重测试和红外光谱测试表征分析了GO/NBR/MMA复合材料的组织和性能。结果:当GO添加量为3%时GO/NBR/MMA复合材料的分散稳定性最佳,Zeta电位值最高且大于40mV,GO缺陷程度最大,热失重剩余质量最高。结论:GO/NBR/MMA复合材料的最佳GO添加量为3%质量分数。     

GO!到非洲去赚钱

HOUSEHOLDS’ BEHAVIOUR AND ENVIRONMENTAL EMISSIONS IN A REGIONAL ECONOMY

Households have significant demand-side potential to drive reductions in atmospheric emissions, including both direct and indirect emissions. Our analysis focuses on the behaviour of a regional economy (Aragon, Spain) and its impact on greenhouse gases (GHG) and sulphur dioxide (SO₂). Using a CGE model, we simulate scenarios and evaluate the environmental impact of adopting changes considered in the Aragonese Climate Change and Clean Energy Strategy. Specifically, we analyse the impact of electricity savings and the promotion of public transport (bus or train) versus private car use. The results indicate that 1 MWh of saving in electricity consumption by households could reduce emissions of GHG by 0.112 kt of equivalent CO₂ and 8.209 kg of SO₂ with a shift in demand preferences and 0.022 kt of equivalent CO₂ and 7.612 kg of SO₂ with an efficiency improvement. Moreover, household changes in demand preferences regarding private/public transport, also contribute to reduce emissions.

WILL THE “TRUE” LABOR SHARE STAND UP? AN APPLIED SURVEY ON LABOR SHARE MEASURES

Labor's share of income is a key variable in economics. It plays a leading role in analysis of (in)equality, globalization, technical change, growth theories, etc. Notwithstanding this broad application, there are many different definitions of the labor share. Understanding and synthesizing those differences is the purpose of this applied survey. Empirical measures may vary reflecting the allocation of income components that cannot be directly ascribed to capital or labor. We examine the alternative assumptions made in the literature in this regard and quantify and motivate the resulting discrepancies. Focusing (mostly) on US data, we show that different measures can have very distinct properties in terms of the observed stochastic trends, shares of short‐, medium‐, and long‐run variation and volatilities, persistence and mean‐reversion properties, and susceptibility to structural breaks. For instance, while “short‐run” properties of the surveyed labor share measures are relatively consistent across all definitions (and countercyclical), their “medium‐” and “long‐run” trends may diverge substantially (and are procyclical). To substantiate our analysis, we document the implications of discrepancies in the empirical labor share definition for growth accounting, analyzing the effect of technology shocks, and for estimating inflation dynamics.
