会计准则的供给与需求

会计信息是一种典型的公共物品,由于存在“市场失灵”、“政府失灵”,无法从根本上回答是政府制定会计准则还是由民间机构制定准则。从准则的供需角度出发,我国会计准则与美国以及国际会计准则的不同具有必然性,因为供给与需求不同,导致各国会计目标不完全相同。目标如不一致,所采用的会计政策与会计方法就会有侧重。

Uncertain Climate Change in an Intergenerational Planning Model

A three-generation planning model incorporating uncertain climate change is developed. Each generation features a production activity based on capital and an exhaustible resource. An irreversible climate change may occur in period two or three, reducing the productivity for this and the remaining generation. The model is solved by stochastic dynamic programming. If the climate impact and climate change probability is constant, the optimal period one (and two) resource extraction is larger than for the reference case of climate stability. If, however, climate impact and climate change probability increases with increased aggregate resource use, this result is reversed.     

惟平惟准 近知近仁——兼评山东工商学院校训

“惟平惟准,近知近仁”含义丰富,对于人生、市场乃至各类管理,都是一个极则。平准是平均、平衡、协调。平,有平衡、平和、平均、平等、太平、和平等意;准,有准的、准则、准绳、标准等意。知是智慧,仁是仁慈。“惟平惟准,近知近仁”要求思维处事讲究利用高标准力求平衡,自强不息。高标准就是大智慧、大仁义和大勇猛等品性,是高级人才的优秀素质。     

美国GE公司CEO继任规划的启示

继任规划在企业追求长期战略和持久业绩的过程中起着关键作用。而CEO继任规划则是企业最重大的战略决策。美国GE公司由于建立了一套行之有效的CEO继任规划程序，从而保证企业能够培养合适的CEO候选人。公司CEO继任规划包括内部接班继任、内部竞争继任、突然政变继任和广泛选择继任等4种方式。每一种继任方式都有其优势和劣势。不存在适用于所有公司的继任方式。不同的公司如何选择适合的继任方式取决于公司本身的条件。目前，我国企业正在进入经营者大换班高峰期，可以借鉴美国GE公司CEO继任规划的成功经验，进一步完善继任机制。     

新围海涂土地利用结构优化模型及其应用

为了进一步探讨数学规划模型在新围海涂土地利用结构优化中的应用,在模型分析与实例应用相结合的基础上,选择浙江沿海新围海涂作为典型研究区,根据当地滩涂开发利用总体规划要求,结合实际开发需要,应用数学规划方法构建土地利用结构优化决策模型,对规划范围内新围海涂的土地利用结构进行优化配置。研究结论:应用数学模型对研究区内土地利用结构优化配置是可行的。但是今后需要进一步研究空间优化配置方法,实现定性、定量和定位三者的统一。     

Portfolio Optimization under Lower Partial Risk Measures

Portfolio management using lower partial risk (downside risk) measures is attracting more attention of practitioners in recent years. The purpose of this paper is to review important characteristics of these riskmeasures and conduct simulation using four alternative measures, lower semi-variance, lower semi-absolute deviation, first order below targetrisk and conditional value-at-risk.We will show that these risk measures are useful to control downside risk whenthe distribution of assets is non-symmetric. Further, we will propose a computational scheme to resolve the difficultyassociated with solving a large dense linear programming problems resulting from these models. We will demonstrate that this method can in fact solve problems consisting of10⁴ assets and 10⁵ scenarios within a practical amount of CPU time.     

Planning Your Own Debt

We model the Danish market for mortgage backed securities with a two-factor interest rate model and use a stochastic programming approach to analyse how an individual home-owner should initially compose and subsequently readjust his mortgage in an optimal way. Results show that the 'rules of thumb' used by financial institutions are reasonable, although best suited for more aggressive mortgagors, for whom the delivery option is of some value. More risk-averse investors should also re-adjust frequently, but use more diversified portfolios. Results are insensitive to whether a one- or two-factor model is used, provided the former is suitably calibrated.

可持续增长率与财务管理目标相关性分析

可持续增长率是企业现有财务资源所能够支持的销售收入的最大增长率,代表企业最适宜的增长速度。企业的财务管理目标是企业价值最大化,而决定企业价值的重要因素是由销售收入增长所带来的未来现金流量。企业以可持续增长率作为销售增长目标,有利于企业价值的持续增加;而将企业价值最大化作为财务管理目标又有利于企业的可持续增长,可持续增长率与财务管理目标密切相关。本文将以可持续增长率与财务管理目标的相关性作为研究起点,试图从财务管理目标的角度来进一步认识可持续长率。
