Natural resources, capital accumulation and the resource curse

Early concern by economists for the effect of natural capital on economic growth gave way to complacency and neglect during the nineteenth century. Evidence has emerged, however, that since the 1960s the economic performance of low-income countries has been inversely related to their natural resource wealth. This relationship is not a deterministic one so policy counts. SEEA can help improve the policy and performance of resource-abundant low-income countries by reinforcing the rationale for the sound management of natural resources and also by providing an index of policy sustainability in the form of the net saving rate. This policy index, along with other measures such as a capital fund for sterilizing the rent, initiatives to increase the transparency of rent flows and the rigorous evaluation of alternative uses of additional public sector revenue can improve the efficiency by which natural resource rent is transformed into alternative forms of capital to sustain rising social welfare. Chad and Mauritania provide case studies to illustrate how SEEA and net saving can be used to diagnose policy failure and improve economic performance.     

股权分置改革前后上市公司绩效变化的研究

选取了177家股改公司,通过对股改前后绩效的分析发现:每股净资产在股改前后不存在显著差异;每股收益、资产利润率、净资产收益率均表现为股改后第一季度指标值显著高于股改前的指标值、股改后第二和三季度的指标值显著低于股改前的指标值、股改后第四季度的指标值与股改前的指标值没有显著差异,并对该结论进行了简单分析。     

Does the Company Lawyer Have Your Back? A Brief Look at the Need for Personal Private Liability Insurance

There are four traditional uses of private personal liability insurance dating from the 1970s to the present (Hayes 1979; Sommers 2005) which pertain either to individuals or corporations. There is insurance to cover damage to rental cars, umbrella insurance to cover any injury to a guest at one’s home, insurance bought by corporations to cover potential corporate responsibility for actions of company representatives and insurance including misadventures with financial information and morally hazardous behavior as well as corporate required actions which are later deemed to be wrong or inappropriate. Employees need to find out if the employee manual provides for coverage for legal liabilities resulting out of performing job responsibilities. Due to a need to reduce company costs, many companies are reducing or eliminating coverage for employees for many types of actions. Private personal liability insurance gives you the peace of mind to know what you are covered for and for how long. Employee rights versus corporate budgets are at the core of this discussion.     

Building the Knowledge Stock: Lags,Depreciation, and Uncertainty in R&D Investment and Link with Productivity Growth

The search for an appropriate methodology to investigate the relation between R&D investment, knowledge stock and productivity growth is the main purpose of the paper. In analogy with physical assets, we present a model of knowledge capital formation which allows the calculation of the relevant user cost, as well. The proposed model accumulates R&D investment based on a stochastic gestation lag and a geometric depreciation of the stock. The basic parameters underlying the lag structure differ according to the types of research expenditure. The approach is applied to public R&D investment in Italian agriculture; the results provide interesting information about the economic structure of public research effort in Italian agriculture and plausible estimates of its internal rate of return.

论平衡记分卡的"不平衡"

国内对平衡记分卡的认识,与发达国家相比还存在很大差距。许多人还没有真正认识到平衡记分卡的含义和用法,仅仅追求形式,使平衡记分卡成为组织"看起来好看,用起来无用的装饰品"。本文提出根据企业实际情况建立精简的"不平衡"记分卡的观点,借以与大家进行深入讨论。     

数量指标和质量指标理论与应用评析

在各类《统计学》教科书中,对数量指标和质量指标概念的解释不大一样,但基本的含义却是相同的。两者从概念上区别并不困难,也容易理解,但在对一些特殊问题的分析时,却不易把握,特别是在比较复杂的统计分析中,那就更不容易做出准确的判断了。怎样才能对数量指标和质量指标的应用做出科学的评价和分析。本文拟就这方面的问题做些初步探索。     

经济增长、收入分配对农村贫困变动的影响

文章利用了基于Lorenz曲线进行贫困测度及其分解的方法,实证研究了1985～2003年中国农村的贫困变动,以及经济增长和收入分配对贫困变动的影响.结果表明,经济增长使农村居民收入增加,大幅度减少了贫困,但农村居民的收入差距逐渐拉大,收入不平等加剧部分地抵消了经济增长的减贫成效.

工序能力指数的新定义及其应用

本文简述工序能力指数的传统定义及其不合理性,其根源是偏移系数的定义有缺陷。改进偏移系数的定义后,将使工序能力指数的定义更加科学、合理,进而给出不合格品率p与C_p、k之间的计算公式和常用数值表,供企业应用时选用。
