与收入相关的健康不平等的动态变化与分解——以我国中老年群体为例

本文首先创新性地将衡量健康不平等的Erreygers指数分解为收入增长效应、收入分布效应、收入流动效应和人群老化效应;然后采用2011年和2013年两期CHARLS基线调查微观数据,以中老年群体为研究对象,通过混合区间回归模型估计健康与收入和非收入变量的关系;在此基础上得到全样本和各特征人群的Erreygers指数,并对与收入相关的健康不平等的动态变化进行分解。结果表明:(1)中老年群体存在亲富的健康不平等,且亲富程度正在加剧;女性和沿海农村地区人群的健康不平等程度相对较高;(2)健康不平等问题的加剧主要源于收入增长效应和收入分布效应,收入流动效应可在一定程度上缓解健康不平等程度,人群老化效应的缓解作用则相当微弱;(3)与农村的负向效应不同,城市人群的收入增长效应和收入流动效应均在不同程度上加剧了健康的亲富不平等。     

Wolf in Sheep's Clothing: The Active Investment Strategies behind Index Performance

This paper argues that the commonly used market indices imply forms of active investment management in disguise. The selection and rebalancing rules make these indices highly exclusive and dynamic regarding their underlying components and significantly bias their performance. Any passive investment tracking these indices turns into an active strategy characterised by market timing and state‐dependent performance. Evidence is provided that exclusive indices outperform (underperform) more inclusive peer indices in upward (downward) markets. The constitution and maintenance rules of exclusive indices correspond to a set of active trading and investment rules similar to momentum strategies.     

欠发达省域经济差异的时空演变分析

基于1989—2012年广西89个县域经济数据,利用分解的Theil指数和马尔可夫链方法,探索欠发达省域差异的时空演变。结果表明:广西区域差异对地理尺度很敏感,县域间的差异最大,其次为地市间,区域间的发展最为平衡。三大区域内部差距的增大是促成广西整体差异拉大的主导力量。广西区域经济发展存在俱乐部趋同现象,2000—2012年间的更为显著,欠发达地区极有可能陷入"贫困陷阱"。区域间的两极分化趋势增强,趋同俱乐部总体上呈环状分布特征。高水平趋同俱乐部的分布逐渐由市辖区扩散到邻近的县域。低水平趋同俱乐部主要分布在桂西资源富集区。中高水平趋同俱乐部环绕高水平趋同俱乐部外围,而中低水平趋同俱乐部集中分布在中高水平趋同俱乐部外围。广西县域单元平稳者居多,向上转移有所增加。     

Is there a case for carbon-based border tax adjustment? An applied general equilibrium analysis

Concern that unilateral Greenhouse Gas (GHG) emission reductions could foster carbon leakage and undermine the international competitiveness of domestic industry has led to growing calls for carbon-based Border-Tax Adjustments (BTAs). This article uses a global general equilibrium model to assess the economic effects of BTAs and comes to three main conclusions. First, BTAs can reduce carbon leakage if the coalition of countries taking action to reduce GHG emissions is small, because in this case leakage (while typically small) mainly occurs through international trade competitiveness losses rather than through declines in world fossil fuel prices. Second, even though the economic effects of BTAs vary somewhat depending on how they are implemented, their welfare impact is typically small, and slightly negative at the world level. Third, and perhaps more strikingly, BTAs do not necessarily curb the output losses incurred by the domestic Energy Intensive-Industries (EIIs) they are intended to protect in the first place. This is in part because EIIs in industrialized countries make important use of carbon-intensive intermediate inputs produced by EIIs in other geographical areas. Another, deeper explanation is that EIIs are ultimately more adversely affected by the existence of a carbon price itself than by any international competitiveness losses. These findings are shown to be robust to key model parameters, country coverage, targets and design features of BTAs.     

Working sick and out of sorts: a cross-cultural approach on presenteeism climate,organizational justice and work–family conflict*

Abstract

A climate of presenteeism has important effects on employee well-being and the organization itself. Our study, based on surveys of health sector employees in six different countries (Brazil, Ecuador, Lebanon, Portugal, Russia and Spain) examines whether organizational justice plays a mediating role in the relationship between a presenteeism climate in the organization and work–family conflict (WFC). Our results indicate that the perception of organizational justice and the presenteeism climate do influence WFC. Moreover, higher levels of WFC were found in non-Latin countries. This study contributes to the work attendance and life balance field by providing cross-cultural empirical evidence corroborating the effect of justice and presenteeism climate on the WFC.

Animal foods and climate change: shadowing eating practices

Animal farming exceeds all forms of transport in terms of global greenhouse gas (GHG) emissions. Despite the implications of the seriousness of addressing animal farming in relation to mitigating the effects of GHG emissions, to date, the relationship between consumer behaviour and climate change has tended to neglect the role of animal foods. This paper reports on a pilot study in which six UK households were ‘shadowed’ to facilitate the investigation of the relationship between animal food practices and environmental practices, as they emerge in day‐to‐day life. Results indicate that most participants make no connection between the two issues at present, in terms of awareness or practice. However, animal foods do have an ambiguous and complex status in most participants' food practices; for instance, being viewed as problematic for reasons of health or animal welfare. This finding suggests that further research is needed into the potential for raising awareness of the link between animal‐based foods and climate change. This might have a role to play in shifting food practices towards more plant‐based, less GHG intensive, foods.     

Measuring a boom and bust: The Sydney housing market 2001–2006

The Sydney housing market peaked in 2003. The period 2001–2006 is, therefore, of particular interest since it captures a boom and bust in the housing market. We compute hedonic, repeat-sales and median price indexes for five regions in Sydney over this period. While the three approaches are in broad agreement regarding the timing of the turning point in the housing market, some important differences also emerge. In particular, we find evidence of sample selection bias in our hedonic and repeat-sales data sets (with the former focusing more on better quality dwellings and the latter more on lower quality dwellings). These sample selection biases could in turn cause bias (in opposite directions) in our hedonic and repeat-sales indexes. Median indexes may likewise be biased as a result of an apparent decline in the average quality of dwellings sold in the latter part of the sample. We also find evidence of convergence in prices across regions during the boom and divergence in the subsequent bust.

我国经济增长预测研究新探——基于分类变量的扩散指标法

基于分类变量的扩散指标方法是在Stock and Watson所提出的扩散指标法的基础上,利用变量之间的相似系数先对变量进行聚类分析,根据各变量的相似程度的大小分为几个变量子集,然后分别从变量子集中提取扩散指标。应用基于变量分类的扩散指标方法对我国经济增长的预测结果表明,同扩散指标法相比,该方法更加充分利用了原始数据中的有用信息,预测精度很高,因而是对经济增长进行预测的另一种有效方法。
