EVA在企业应用中的思考

国资委于2009年下发了EVA考核办法,为央企考核提供了新的思路。但由于运行时间短,企业没有可参考的模式进行借鉴,在实际运行中出现了一些值得大家商讨的问题。因此,文章针对企业应用中出现的问题,提出了相应的改进措施。     

实时财务报告技术采纳与资本成本——基于“创新接受”视角的理论模

在资本市场中,公司与其对手为获得更低的资本成本展开竞争。为了达成目标,公司都尝试采用新的信息技术来提高信息披露的透明度。扩展组织"创新接受"理论的内容并整合影响实时财务报告技术采纳和资本成本的主要因素,利用数学模型建构两者之间的约束关系,结果发现,资本成本的节省、不确定性、风险规避、交易、转换成本以及公司治理政策等都对公司何时以及是否采纳实时财务报告技术产生影响。     

定向增发公告效应在股市中的异化现象——关于中国证券市场的实证研究

本文以中国证券市场2006～2008年成功进行定向增发的上市公司为样本,研究了定向增发公告效应在牛市、熊市中的异化现象。研究发现在牛市周期中仅仅公告日当天存在显著的正公告效应,公告日前后都不存在显著的正公告效应;但是在熊市周期中不仅公告日当天存在显著正公告效应,而且从公告日前两天开始一直到公告日后10天都存在显著正公告效应。在不同市场态势下,公告效应与折扣的关系也不相同:在熊市周期中,随着定向增发折扣的增加,公告效应相应减弱,而在牛市周期中公告效应增强。最后,论文给出了基于投资者情绪的理论解释以及相应的启示。

经济转型下的外商直接投资、国内资本与经济增长——基于中国时间序列数据的计量检验与实证分析

经济转型背景下,中国经济持续增长的一个重要原因是引入外商直接投资。本文对1985年-2010年中国外商直接投资、国内投资与经济增长的总量时间序列数据进行了实证分析。结果表明:FDI与国内资本对我国的经济增长的影响显著,都是GDP的格兰杰原因,与经济增长存在长期均衡关系;但FDI对经济增长的影响小于国内资本,并且FDI与国内资本还存在相互挤入效应。     

Global indeterminacy in an endogenous-growth model with public capital

This paper studies the patterns of growth in an endogenous-growth model where the labor supply is endogenous and sustained growth arises because the services derived from public capital increase the economic productivity. It is assumed that these services are congested by the number of households in the economy but they are not congested by the units of time that each household devotes to work. With this assumption, the dynamic equilibrium exhibits multiple balanced-growth paths, local and global indeterminacy, and limit cycles under some plausible fiscal policies. Our analysis points out that a large lump-sum tax is a necessary condition to obtain this complex equilibrium dynamic behavior.     

The Tyranny of Concepts: CUDIE (Cumulated, Depreciated, Investment Effort) Is Not Capital

The cost of public investment is not the increment to the value ofpublic capital. Unlike with private investors, there is no plausiblebehavioral model in which every dollar that the public sectorspends as ``investment' creates economically valuable ``capital.'While this simple analytic point is obvious, it has so far beenuniformly ignored in the empirical literature on economic growth,which uses—at best—cumulated, depreciated, investmenteffort (CUDIE) as a proxy for capital stocks. However, particularlyfor developing countries the difference between investment costand capital value is of first-order empirical importance: governmentinvestment is half of more of total investment, and calculationspresented here suggest that in many countries government investmentspending has created little useful capital. This has implicationsin three broad areas. First, none of the existing empirical estimatesof the impact of public spending has identified the productivityof public capital. Even where public capital has a potentiallylarge contribution to production, public-investment spendingmay have had a low impact. Second, it implies that all estimatesof total factor productivity in developing countries are deeplysuspect as there is no way to empirically distinguish betweenlow growth because of investments that create no factors andlow growth due to slow productivity growth. Third, multivariateregressions to date have not adequately controlled for capitalstock growth, which leads to erroneous interpretations of regressioncoefficients.     

Microfinance and social capital formation- a social network analysis approach

The microcredit program has emerged as an important poverty alleviation strategy over the last three decades, and several studies have examined its economic impacts on the community well-being. However, far too little attention has been paid to the effects of micro credits on community social connection and solidarity. This paper aims to examine the application of Social Network Analysis (SNA) to explore the impact of the rural microcredit fund on community social capitals. In doing so, the data on interactions of four rural development groups' members before and after the microcredit project implementation were collected using participatory workshops in Neyzar village of Qom province in Iran. The data were analyzed by Ucinet software, and the socio-graphs were produced by the NetDraw application. The results show that, more people have been involved in the social interactions after the project implementation and there was statistically significant increase in density and decrease in centralization of cooperation network. Furthermore, there were no important distinctions in centrality of people with various educational levels before and after the project implementation. Overall, it can be concluded that, the microfinance initiative considerably promotes the community social capital and participation in the rural development activities. Moreover, the SNA techniques are applicable as an impact assessment tool to investigate changes in community social capital.     

Optimal investment with vintage capital: Equilibrium distributions

The paper concerns the study of equilibrium points, or steady states, of economic systems arising in modeling optimal investment with vintage capital, namely, systems where all key variables (capitals, investments, prices) are indexed not only by time but also by age. Capital accumulation is hence described as a partial differential equation (briefly, PDE), and equilibrium points are in fact equilibrium distributions in the variable of ages. A general method is developed to compute and study equilibrium points of a wide range of infinite dimensional, infinite horizon, optimal control problems. We apply the method to optimal investment with vintage capital, for a variety of data, deriving existence and uniqueness of equilibrium distribution, as well as analytic formulas for optimal controls and trajectories in the long run. The examples suggest that the same method can be applied to other economic problems displaying heterogeneity. This shows how effective the theoretical machinery of optimal control in infinite dimension is in computing explicitly equilibrium distributions. To this extent, the results of this work constitute a first crucial step towards a thorough understanding of the behavior of optimal paths in the long run.     

Knowledge capital,CEO power,and firm value: Evidence from the IT industry

Disruptive innovation dramatically changes the demand of a product market in the information technology (IT) industry. In response to the impact of disruptive innovation, IT firms that may be eliminated from the competitive race actively develop innovative products and adjust their operating strategies to strengthen their survivability in the fiercely competitive market. Thus, this study explores the factors that affect firm value in the IT industry under the impact of disruptive innovation. The empirical results reveal that knowledge capital and CEO power play crucial roles in explaining firm value. IT firms with powerful CEOs and increased knowledge capital have high firm values. The effects of knowledge capital and CEO power on firm value are especially significant for founder and duality CEO firms. Furthermore, the influence of CEO power is more prominent in periods of financial crisis.
