湖北省碳排放与经济增长脱钩分析

以2000-2014年湖北省GDP、能源消费和碳排放为基础数据,从能源结构、能源消耗强度和碳排放强度方面分析在此期间湖北省能源利用现状以及变化趋势,并且利用Tapio脱钩模型,分析湖北省2001 -2014年间经济增长与碳排放之间脱钩关系,将能源消费作为中间变量说明脱钩状态变化的原因。结果表明湖北省在此期间经济增长与碳排放绝大多数处于弱脱钩状态,并有向强脱钩转变的趋势,并且分析原因主要是经其二者与能源消费结构的改善和能源能利用率的提高有密切关系。最后就区域层面、企业层面以及个人层面提出相关建议。     

基于排队论的公交站点停车位优化及实证分析

优化设计公交站点停车位数是站点建设的一步重要工作,停车位数过多或过少都会影响公交系统的运营效率和服务质量。鉴于此,此文将探讨基于排队理论的公交站点停车位数优化方法,并以武汉市街道口站为例,运用该方法进行了实证分析,以期对武汉市的公共交通建设提供理论上的参考。     

安徽非公经济发展研究

在当代中国,非公经济发展与改革开放及制度变迁原本是相通的,欠发达地区经济发展的实质就是非公经济的发展;安徽非公经济发展滞后的深层机理在于既定制度格局下的路径依赖。本课题深入分析了既定制度格局影响安徽非公经济发展的机制过程,以此为基础,提出了进一步加快发展的思路和对策。     

企业融资偏好解析——基于农业上市公司的实证数据

自MM理论以来,企业融资行为的理论与实证研究不断深入.大多国内研究文献认为我国企业融资行为具有明显的股权融资偏好.文章运用新的研究思路与方法,对我国农业上市公司的融资偏好与融资结构特征分别进行了实证研究,结果发现虽然融资结构特征体现出明显的股权融资依赖性,但企业并不具有股权融资偏好.

"资源诅咒"视角下的西部地区经济增长

西部地区自然资源富集,但经济增长相对缓慢,出现了"富饶的贫困",存在着所谓的"资源诅咒"。自然资源丰富在某种程度上确实是经济增长的优势,但如果开发利用不当,或仅仅将眼光集中在资源上,就很容易转化为经济发展的劣势。资源丰富的西部地区必须跳出资源诅咒,实现经济快速健康增长。     

Marx,Sraffa, and Surplus: Observations Prompted by Garegnani (2018)

ABSTRACT

In a posthumously published article, Pierangelo Garegnani (2018. ‘On the Labour Theory of Value in Marx and in the Marxist Tradition.’) depicts Marx’s project in Capital as that of ‘developing systematically the theory of Ricardo and [the] implications of social conflict’ implied by Ricardo’s ‘surplus approach to value and distribution’. This paper argues to the contrary that Marx’s theory of surplus value and exploitation differs from (neo-)Ricardian surplus theory in fundamental ways, and modifies Garegnani’s simple Sraffian model to illustrate the distinctive implications of Marx’s theory.     

Forecasting portfolio-Value-at-Risk with nonparametric lower tail dependence estimates

We propose to forecast the Value-at-Risk of bivariate portfolios using copulas which are calibrated on the basis of nonparametric sample estimates of the coefficient of lower tail dependence. We compare our proposed method to a conventional copula-GARCH model where the parameter of a Clayton copula is estimated via Canonical Maximum-Likelihood. The superiority of our proposed model is exemplified by analyzing a data sample of nine different bivariate and one nine-dimensional financial portfolio. A comparison of the out-of-sample forecasting accuracy of both models confirms that our model yields economically significantly better Value-at-Risk forecasts than the competing parametric calibration strategy.     

When profession trumps potential: The moderating role of professional identification in employees’ reactions to talent management

Abstract

This study aimed to investigate the role that a professionalized context plays in shaping employee reactions to talent management decisions. We examined the mediating role of felt obligation in the relationship between talent ratings and organizational citizenship behavior. Further, the study tested whether professional identification moderates the relationship between talent ratings and felt obligation towards the organization. Five hundred and ninety-eight teachers that had recently received ratings of their talent status responded to a survey questionnaire. Felt obligation mediated the relationship between talent ratings and organizational citizenship behavior. Furthermore, professional identification moderated the relationship between ratings of potential and felt obligation in such a way that the relationship was strongest for the teachers expressing the lowest professional identification. At high levels of professional identification, the relationship was not significant. These results indicate that conventional talent management might be less effective for increasing favorable attitudes and behaviors among employees in highly professionalized contexts, such as the education sector.     

The accountable governance of provincial governments of a Pacific island country

ABSTRACT

Using the theory of indigenous alternatives and a benchmark of indigenous financial reporting expectations, this paper examines the challenges to accountable governance of the nine provincial governments of the Solomon Islands for the years 1998 to 2017. Every provincial government consistently received disclaimed or qualified opinions from the state auditor. The author explains why the regional development of all provinces of the Solomon Islands could be improved if rudimentary forms of financial reporting were to be addressed.
