基于要素分析的生态产业发展与对策

生态产业是实现循环经济的产业基础。面对环境的压力和国际技术壁垒的挑战,在我国建立生态产业具有十分重要的意义。生态产业能否顺利推行取决于制度、技术、市场、人才、管理等相关因素的综合作用。     

人力资本概念产生的分析

人力资本概念自从20世纪60年代由西奥多.舒尔茨正式提出以来,在经济学界受到了广泛的关注。按照英国著名经济思想史学家马克.布劳格的说法,"在鲍曼确切地把人力资本的概念的提出称为20世纪60年代的‘经济思想上的人力投资革命’以前,把在诸如保健和教育这样的社会服务上的支出当作与在物质资本上的投资一样的投资,是一件非同寻常的事情。"人力资本概念的提出无可厚非是观念上的创新与突破,但是在面对这种创新与突破的同时,许多的学者似乎误入歧途,仅仅对人力资本的概念做表面上的理解,脱离了它产生的社会背景、技术背景和理论背景。许多人置资本的内在规定性于不顾,牵强地对人力资本下定义。在这样的视角下,不仅工业时代有人力资本,就连远古时期也存在人力资本。文章希望通过从人力资本概念产生的角度分析人力资本概念的内涵,从而真正解释什么才真正属于人力资本的范畴。

Role of culture in water resources management via sustainable social automated negotiation

Increased competitions for water resources in many regions worldwide call for cooperative approaches. The competitions are complex for humans to resolve due to numerous alternatives and different or conflicting preferences of multiple stakeholders over multiple criteria, which might even oppose desirable environmental objectives. Parties also have incomplete information about the preferences of the counterparties. Electronic negotiation, empowered by intelligent agent technology, is a combination of artificial intelligence, economics, and psychology to find beneficial joint agreements in complex paradigms such as this. This study investigates a multilateral sustainable automated negotiation among intelligent agents representing stakeholders, including the legal party ‘nature’ as one of the stakeholders. It defines decision criteria and alternatives in the framework of cultural factors, elicits preferences of the stakeholders regarding the criteria without their intervention using a multi-criteria decision-making method, prunes the solution space before starting the negotiation by recognizing a general social treaty, determines the multi-issue specific treaty by learning the stakeholders, and demonstrates bidding and acceptance strategies.

Introducing Environmental Variables in Nonparametric Frontier Models: a Probabilistic Approach

This paper proposes a general formulation of a nonparametric frontier model introducing external environmental factors that might influence the production process but are neither inputs nor outputs under the control of the producer. A representation is proposed in terms of a probabilistic model which defines the data generating process. Our approach extends the basic ideas from Cazals et al. (2002) to the full multivariate case. We introduce the concepts of conditional efficiency measure and of conditional efficiency measure of order-m. Afterwards we suggest a practical way for computing the nonparametric estimators. Finally, a simple methodology to investigate the influence of these external factors on the production process is proposed. Numerical illustrations through some simulated examples and through a real data set on Mutual Funds show the usefulness of the approach.JEL Classification: C13, C14, D20     

UNDERSTANDING THE INTERACTION BETWEEN INTERNATIONAL AND EURO AREA OUTPUT VOLATILITY

This paper addresses two main questions. First, it seeks to establish whether the stylized facts of the ‘great moderation’ that have been documented for the UK and US economies can be found for the Euro area. Second, it explores possible explanations for any changes that have occurred in the volatility of Euro area output fluctuations. In examining why business cycles have moderated, much of the existing literature has tended to concentrate on a few key factors. These include shifts in the structure of the economy, improved monetary policy and a ‘good luck’ factor. This paper, however, follows a relatively new branch of the great moderation literature by focusing on whether international business cycle linkages have changed in a way that may have perpetuated the dampening in Euro area output fluctuations. The results show Euro area output fluctuations to have significantly reduced in variability over the last quarter of a century. The results go on to highlight that, although Euro area cycles differ little from rest of the world cycles, the moderation in Euro area output fluctuations is only marginally due to changes in international business cycle linkages and smaller international and domestic shock variances.     

北京市房地产价格影响因素分析及限购政策绩效评估

随着经济的高速发展,城市的房价也呈现出急剧攀升的态势,脱离了正常的价格波动轨道,大大增加了城市居民的生活成本。以首都北京为例,房价的上升幅度远远超过预期。在经济理论的基础上,运用近几年北京房地产行业的统计数据建立回归模型,可以对影响北京房价的因素进行分析,并且可以对北京市政府2011年2月出台的＂京八条＂限购政策进行绩效评估。
