Real Options, (Dis)Investment Decision-Making and Accounting Measures of Performance

This paper suggests that a residual income-type measure of performance can be designed which supports optimal investment and disinvestment decision-making in a real options framework involving the options to wait before investing and to abandon. The measure has a number of advantages and disadvantages. Nonetheless, the balance of advantage versus disadvantage for the proposed measure must be set against the inadequacies of other competing measures of performance and associated organisational designs. Even if the measure of performance suggested is not regarded as practically useful, it has another general advantage – it can be used as a benchmark against which to evaluate other performance measures with regard to their support of optimal investment and disinvestment decision-making in a real options framework.     

对生产资料所有制问题的政治经济学思考

生产资料所有制实际上是一个积累主体的选择问题。不同的积累主体具有不同的积累动力和积累效率，从而决定着生产资料积累的状况，进而成为人们考虑选择积累主体的重要因素。由于生产资料所有者承担着积累主体的职能，因此他必然要凭借生产资料的所有权参与社会产品的分配，获得一个相应的份额，做为进行生产资料积累的物质基础。生产资料所有者的社会福利水平应以他用于消费的部分为依据，将其同社会的一般福利水平进行比较，由此来     

Consumption externalities and the effects of international income transfers on the global environment

In this paper, we extend the standard model of private provision of public goods by including consumption externalities to characterize a situation in which economic activities pollute the environment. We consider a case in which there are an industrial country which can afford to invest in the environment and a developing country which cannot. Then, we show that international income transfers in both directions can improve the global environmental quality as well as the welfare of each country. We also show that the results have important implications for policies such as official development assistance or the assignment of tradable emission permits.     

三主桁连续钢桁拱桥整体节点有限元分析

东平水道桥是武广高速铁路上一座四线铁路桁架拱桥,主跨结构为99m+242m+99m的三主桁连续钢桁拱,主桁采用整体节点形式,三主桁内力分析表明中桁处受力最大。节点板联结着主桁、腹杆、横梁、平联等各类杆件,结构及受力均较复杂,节点应力分布是设计中的关键问题之一。文章利用有限元程序对其特殊位置节点板进行应力分析,研究了其应力分布及传力特性,为设计提供依据和给同类桥梁提供参考。研究表明通过调整节点构造和板件刚度,节点具有足够的受力与传力功能。     

Must we choose? European unemployment, American inequality, and the impact of education and labor market institutions

In the last 15 years, two equilibria have arisen in the advanced world. On the one hand, wage dispersion has widened in those countries where unemployment has remained low (with cyclical variations). On the other hand, wherever income inequality has remained unchanged, unemployment has shot upwards. To account for these distinct patterns, we develop a political–economic model showing that, controlling for the skills of the population, the effects of technological and trade shocks (that have affected OECD nations) that are contingent on the institutional rules in place. Economies with generous unemployment allowances adjust through subsidized unemployment. By contrast, low levels of social protection lead to less unemployment but wider wage dispersion. The level of qualifications of the labor force determines the extent of the adjustment for a given institutional arrangement. We derive, in turn, the institutional structure of each country from the political conditions in place at the time of the shock. The empirical part successfully tests the model for the sample of European regions and US states.

试论按劳分配与按劳动力价值分配

随着市场经济体制改革的深入，解决旧的问题的同时又不断地产生一些新的问题。这些问题的产生是体制转轨过程中的必然现象，如果不及时解决，必将影响我们改革成果的巩固和改革的进程。因此，必须对这些问题给予重视并从理论上使其得到合理的解释。例如：现阶段我国的劳动力是否为商品 ?生活资料的分配是否仍坚持按劳分配 ?按劳分配与按劳动力分配的关系又是如何 ?这些问题都将在本文中得到阐释，以为我国的改革进程廓清迷雾。     

长期股权投资权益法核算下会计与税法的差异

由于我国实行的是税会分离模式,因此税法上在确定应纳税所得额和会计在确认利润的时候,二者之间必然有很多的差异,既有永久性的差异也有时间性的差异,长期股权投资权益法导致的差异比较难以把握,因为当会计对长期股权投资采用权益法核算的情况下从取得长期股权投资到最后的处置每一个环节都存在会计处理和税法规定不相一致的地方。     

陕西省城乡居民收入差距的实证分析

自1981～2005年的25年间,以5年为一个考察期,对陕西省城乡居民平均绝对收入差距、平均相对收入差距进行考察和分析,发现在5个考察期中,陕西城乡居民平均绝对收入差距呈现指数增长的趋势,平均相对收入差距也在不断的上升。笔者认为只有不断对二元制度进行一元化改革和调整,以及在对农业方面进行持续和力度足够投资的基础上,才能在根本上缩小陕西城乡居民收入差距,缓解由城乡收入差距带来的各种社会矛盾,从而有利于和谐陕西早日实现。     

Foreign enclaves and economic development: A theoretical analysis

We consider an urban foreign enclave with sector-specific foreign capital in an otherwise mobile-capital Harris-Todaro model. We consider the taxation of foreign capital. A dynamic version of this model is considered. The long-run equilibrium and the comparative steady-state effects are analyzed. We get some interesting effects of reduction in tax rate on foreign capital on the short-run and the long-run equilibrium levels of domestic factor income and national income under some meaningful conditions.
