环境会计核算体系总体框架研究——基于林纸一体化企业资源的视角

森林资源资产价值没有得到应有的实现和补偿,是我国林纸一体化改革进程缓慢的原因之一。本文运用资源和环境价值核算和成本分析方法,对该问题进行了系统结构分析,构建了林纸一体化企业REA的体系框架。研究了该体系中林纸一体化企业REA的目标、基本前提、一般原则、信息质量要求和核算对象等,并指出林纸一体化企业REA的过程包括资源——环境要素的确认、计量、记录和报告等步骤。所构建的林纸一体化企业资源——环境核算体系将为企业进行森林资源资产和环境成本核算提供理论和方法指导。     

Nonlinear effects of monetary policy on stock returns in a smooth transition autoregressive model

This paper employs smooth transition autoregressive (STAR) models to investigate the nonlinear effect of monetary policy on stock returns. The change in the Federal funds rate is used as an endogenous measure of monetary policy, and the growth rate of industrial production is also considered in the model. Our results show that the relationship between the monetary policy and excess returns on stock prices is positive and nonlinear. A decrease in the Federal funds rate causes a larger increase in excess returns if excess stock returns are located in the extreme low excess returns regime.     

A note on the decomposition (at a point) of aggregate excess demand on the Grassmannian

This paper analyzes the properties of aggregate excess demand functions for economies with an arbitrary finite set of N commodities where agents face trading restrictions of a general, abstract form: their budget set is defined by K-dimensional planes in ^N. It is shown that, if there are at least K agents in the economy, the only general property satisfied by the value of aggregate excess demand and its derivative, at any arbitrary point, is Walras Law. The result is established by considering an economy where agents' preferences are of a ‘generalized Leontief' type.     

需求价格弹性和销售收入关系的数学探析

文章认为,许多经济学教材中关于需求价格弹性对销售收入影响的结论存在明显缺陷,通过严格的数学分析,无论如何都不能得出需求价格弹性大于1时,降价会使销售收入增加这样的结论。正确的结论应该是:对同一条需求曲线,对应不同的点有不同的弹性,中点的价格弹性为1,是销售收入最大点,销售收入的变化由销售点在需求曲线上的位置及移动方向共同决定。

从特变电工看欠发达地区非优势资源依托企业的成长模式

优势资源是一个地区经济发展的重要条件,拥有优势资源的地区通常通过实施优势资源转换战略来实现地区经济的快速发展。然而,特变电工给我们提供了一个欠发达地区非优势资源依托企业的成功范例。这说明:(1)在欠发达地区,只要发展思路正确,发展战略得当,管理措施到位,非优势资源依托企业不仅可以生存,而且可以发展壮大;(2)企业家精神是欠发达地区企业成长的原动力;(3)地缘因素是欠发达地区制造类企业的重要制约因素。     

南京市老年人养老服务需求研究

本文通过对南京市老年人口养老服务需求的调查研究,发现:在健康状况和生活自理能力弱化的预期下,选择机构养老的老年人口比例增加;高收入老年人的机构养老的意愿明显高于低收入或没有收入的老年人;市区老人在各项居家养老服务的知晓率上明显高于郊区老人;空巢老年人的居家养老服务需求率明显高于非空巢老人;老年人对水电气维修服务、医疗咨询和保健服务、精神慰藉等居家养老服务的需求比例较高。最后,针对上述结论提出完善南京市养老服务体系建设的对策。     

The impact of ICT on the demand for skilled labour: A cross-country comparison

This paper provides a unique cross-country comparative perspective on the impact of information and communication technology on the demand for skilled labour. It employs panel data for the US, the UK and France, comprising several skill categories for each country for the 1980s and 1990s. The paper considers the issue of whether skill bias is transitory or permanent both by considering changes through time and by dividing the highly skilled into IT specific and other occupations. The results indicate that the impact of technology on the demand for skilled labour is slowing down, at least in the US, supporting a transitory interpretation.     

基于灰色评判的低需求型车辆器材需求函数确定模型

为解决器材管理人员在确定低需求器材需求分布函数时没有进行假设检验而采用过于主观的方法从而导致需求预测不准的的问题．本文运用模糊灰色评判的方法构建了低需求车辆器材需求函数确定模型。并通过实例验证了其正确性和可行性。事实证明该方法可充分刺用灰色理论在处理小样本数据和模糊数学的优点来较客观的确定器材的需求函数．从而有效提高预测效率。     

A review of the literature on environmental innovation management in SMEs: implications for public policies

The aim of this article is to collect and make up the most important contributions in the economic literature in relation to the special characteristics of the management of the environmental innovation in the SMEs. Specifically, we want to show their strengths and weaknesses in order to make up the main conclusions of these analyses with the literature in relation to the way Public Administrations face this situation. The scarce development in the SMEs in respect to their environmental strategy may be a consequence of the links among some of the following factors: limited financial resources, the type of organizational structure, a little influence of the strategic adaptation competence against the changes in the SMEs, the managers’ scarce environmental training and short term orientation, the staff’s scarce environmental awareness and training, the status of the environmental issues in the company, the SMEs’ lower ability to obtain highly radical innovations, the scarce influence of manufacturing process flexibility in the most advanced states of the environmental strategy in the SMEs and their lack of relation ability with external stakeholders—very important in the success of the most advanced environmental approaches. Besides, the lack of regulation neutrality must be added as a key difference among companies of different sizes. So specific actions seem be necessary, such as technological advice and awareness, and training programs in order to cooperate with external stakeholders.

股权分置改革后,非流通股转为受限股票,取消受限股票的流通限制而实现全流通是股改后中国证券市场面临的又一重大课题。本文介绍了雀巢公司在1988年取消受限股票限制的方案及市场对该方案的反应,并通过建立数学模型对方案进行理论分析,结果表明,股票需求价格弹性(e)及受限股本与不受限股本比值(q)是影响取消限制后全体股东利益的关键因素。最后,根据模型的研究结论,本文对中国上市公司“股改”后受限股票全流通问题提出了相应解决对策。

A note on the closed-form solution to the Lucas–Uzawa model with externality

Ruiz-Tamarit [2008. The closed-form solution for a family of four-dimension nonlinear MHDS. Journal of Economic Dynamics and Control 32, 1000–1014] provides a closed-form solution to the two-sector model of endogenous growth with externalities. He assumes that the coefficient of the relative risk aversion is equal to the physical capital share, but this assumption is empirically and theoretically implausible. This note uses the result of Boucekkine and Ruiz-Tamarit [2008. Special functions for the study of economic dynamics: the case of the Lucas–Uzawa model. Journal of Mathematical Economics 44, 33–54] and derives a closed-form solution without setting the parametric assumption. The solution path is expressed in terms of the Gauss hypergeometric functions.     

A method for estimating the timing interval in a linear econometric model, with an application to Taylor's model of staggered contracts

This paper describes and implements a procedure for estimating the timing interval in any linear econometric model. The procedure is applied to Taylor's model of staggered contracts using annual averaged price and output data. The fit of the version of Taylor's model with serially uncorrelated disturbances improves as the timing interval of the model is reduced.
